COMBINATION OF PEDAL–POWERED HACKSAW ,CHARGER AND WASHING MACHINE

Introduction

The power hacksaw machine, which runs on electric power, works on the principle of the conversion of rotational motion to oscillatory motion. The bicycle also uses the same principle. To give shape to his idea, firstly buy an old bicycle from a scrap market, then cut the pedals of the bicycle from 12 cm to 8 cm and welded it as per requirement and re-affixed the pedals to it.

To use a guide to control the hacksaw blade which is used to cut the metal. Metal slabs were fitted on the hacksaw blade to ensure pressure on the object to be cut and linear movement of the blade. A clamp, with 360 degree rotation, was fixed to hold the metal pieces while cutting, and to allow them to be cut in any shape and angle.

Since a lot of energy is produced during the pedaling process, we will envision utilising it productively. We will fix a dynamo and a 12-volt battery to store the energy. To transfer the energy generated from dynamo to the battery, a forward-biased diode will use. The saved energy can be use to light a 12-volt bulb, which comes in handy while working in the dark.

Since a lot of energy is produced during the pedaling process, we will envision utilizing it productively. We will use the rotation of the cycle to rotate the attached bucket (PEDAL POWERED WASHING MACHINE).

Design and fabrication of drill tool dynamometer-Mechanical Project

Introduction:

Dynamometers are devices used to measure cutting forces in machining operation. The cutting force cannot be detected or quantified directly but their effect can be sensed using Transducer. For example, a force which can neither be seen nor be gripped but can be detected and also quantified respectively by its effect and the amount of those effects (on some material) like elastic deflection, deformation, pressure, strain etc.

These effects, called signals, often need proper conditioning for easy, accurate and reliable detection and measurement. In other words,

Design and fabrication of drill tool dynamometer

Measurement involves three stages

Conversion into another suitable variable (deflection, expansion etc)
Amplification, filtration and stabilization
Reading or recording

Measurement of cutting force(s) is based on three basic principles:

measurement of elastic deflection of a body subjected to the cutting force
measurement of elastic deformation, i.e. strain induced by the force
measurement of pressure developed in a medium by the force.

Requirement of a cutting force dynamometer

The dynamometer should have sufficient mechanical rigidity to avoid excessive deformation of the cutting edge under the action of cutting forces
It should have sufficient sensitivity to enable measurement of cutting forces with sufficient accuracy
It should have high stiffness and low mass, ensuring 100 percent transmissibility of force by its very high natural frequency. This feature will also enable the recorded force to be unaffected by the exciting vibration due to machining process itself. Example : milling , grinding and shaping
It should be capable of indicating individual force components without any cross effect, while measuring such forces simultaneously
The measuring system should be stable with reference to time, temperature and humidity, requiring only occasional checking after calibration.

Drilling dynamometer

Physical construction of a strain gauge type 2 – D drilling dynamometer for measuring torque and thrust force is typically shown schematically in Fig.and pictorially in Fig.. Four strain gauges are mounted on the upper and lower surfaces of the two opposite ribs for PX – channel and four on the side surfaces of the other two ribs for the torque channel. Before use, the dynamometer must be calibrated to enable determination of the actual values of T and PX from the voltage values or reading taken in SMB or PC.

Schematic view of construction of a strain gauge type drillin dynamometer.

Schematic view of construction of a strain gauge type drilling dynammometer

Increasing deflection, δ enhances sensitivity of the dynamometer but may affect machining accuracy where large value of δ is restricted, the cutting forces are suitably measured by using the change in strain caused by the force.

The strain, ε induced by the force changes the electrical resistance, R, of the strain gauges which are firmly pasted on the surface of the tool-holding beam as

Gauge Factor = (Change in resistance /original resistance )

Force Measurement by strain gauge based Transducer

The gauge connections may be

• full bridge (all 4 gauges alive) – giving full sensitivity

• half bridge (only 2 gauges alive) – half sensitive

• quarter bridge (only 1 gauge alive) –1/4 th sensitivity

Design and Fabrication of a Universal Coupling (Hooke's Joint ) Report Download

Abstract

A coupling is a device used to connect two shafts together at their ends for the purpose of transmitting power. The primary purpose of couplings is to join two pieces of rotating equipment while permitting some degree of misalignment or end movement or both.

A Universal coupling is a special type of coupling in which misalignment of shafts is allowed.

Shafts are free to move any direction in order to transmit torque or power from one shaft to another.

In this project work a Universal coupling was designed, in which safe torque on shafts and pin size of cross determined.

Finally the Universal coupling made by Mild Steel, which is low cost and available in every

workshop.

Introduction:

Couplings are mechanical elements that ‘couples’ two drive elements which enables motion to be transferred from one element to another. The drive elements are normally shafts. We tend to see lot of applications of the couplings mainly in the automobiles, for example the drive shaft which connects the engine and the rear axle in a bus or any automobile is connected by means of a universal joint.

The primary purpose of couplings is to join two pieces of rotating equipment while permitting some degree of misalignment or end movement or both. By careful selection, installation and maintenance of couplings, substantial savings can be made in reduced maintenance costs and downtime.

There are various types of coupling based on area of application and misalignment or degree of freedom to move in any direction. Such as the universal coupling allows the shafts to move in any directions.

Universal Coupling or Hooke’s coupling:

A universal joint, (universal coupling, U-joint, Cardan joint, Hardy-Spicer joint, or Hooke's joint) is a joint or coupling that allows the shafts to 'bend' in any direction, and is commonly used in shafts that transmit rotary motion. It consists of a pair of hinges located close together, oriented at 90° to each other, connected by a cross shaft. The universal joint is not a constant velocity joint.

Basic of Universal Joint

A universal joint is like a ball and socket joint that constrains an extra degree of rotational freedom. Given axis 1 on body 1, and axis 2 on body 2 that is perpendicular to axis 1, it keeps them perpendicular. In other words, rotation of the two bodies about the direction perpendicular to the two axes will be equal.

In the picture, the two bodies are joined together by a cross. Axis 1 is attached to body 1, and axis 2 is attached to body 2. The cross keeps these axes at 90 degrees, so if you grab body 1 and twist it, body 2 will twist as well.

A Universal joint is equivalent to a hinge-2 joint where the hinge-2's axes are perpendicular to each other, and with a perfectly rigid connection in place of the suspension.

Universal joints show up in cars, where the engine causes a shaft, the drive shaft, to rotate along its own axis. At some point you'd like to change the direction of the shaft. The problem is, if you just bend the shaft, then the part after the bend won't rotate about its own axis. So if you cut it at the bend location and insert a universal joint, you can use the constraint to force the second shaft to rotate about the same angle as the first shaft.

Types of Universal coupling:

The universal couplings are categorized as-

i. Single joints

ii. Double joints

iii.Telescopic or assembled joints

Field of Applications of Universal Coupling:

Typical applications of universal joints include-

AUTOMOBILE
Aircraft
Appliances
Control mechanisms
Electronics instruments
Medical & optical devices
Ordinance radio
Sewing machines
Textile machineries etc

Universal Coupling (Hooke's Joint )

Conclusion:

Mechanical design is a complex undertaking, requiring many skills. Design and fabrication of a Universal coupling was done in this project work. In designing problem safe torque on shaft was determined. The cross pin size (diameter) was determined considering bearing stress, shearing stress and bending stress taken into account. The application of a universal coupling also studied in this project work.

PNEUMATIC SHEET PUNCHING MACHINE

Synopsis

A pneumatic machine can be thought of as a large flexible mechanical structure that is moved by some sort of control system. The control system takes its input from a human operator and translates this command into the motion of actuators, which move the mechanical structure. The high performance and highly powerful, Pneumatic punching machine vice with the capacity for high volumes of punching has done.

Punching is a operation of producing permanent impression over a job, it historical day it is done by hammering, where nowadays it is done pneumatic machine with accessories

One form of inefficiency in current systems is due to the link between the flows of the two ports of the cylinder. This is because most valves use a single spool to control the flow in both ports. Because of this link, it is impossible to set the pressure levels in the two sides of the cylinder independently.

Therefore, the outlet side will develop a backpressure, which acts in opposition to the direction of travel, which increases the pressure required on the inlet side to maintain motion. Since the force generated by the actuator is proportional to the pressure difference between the two sides, the actual pressures in the cylinder don't affect the action of the cylinder.

Generally, Pneumatic cylinder operations are based on Pneumatic pump operation. Air is pumping to the Pneumatic cylinder by using Pneumatic pump system. It’s the manual operation.

Pneumatic Punching Machine

Advantages:

1)More efficient

2)Power can be easily transmission.

3)Less loss in transmission.

4)Very Easy Holding Process

DESIGN AND FABRICATION OF TOGGLE JACK REPORT DOWNLOAD

ABSTRACT

Toggle jacks are simple mechanisms used to drive large loads short distances. The power screw design of a common Toggle jack reduces the amount of force required by the user to drive the mechanism. Most Toggle jacks are similar in design, consisting of four main members driven by a power screw. In this report, a unique design of a Toggle jack is proposed which is very easy to manufacture. Each member, including the power screw sleeves, is made of the common c-shape. This eliminates the need for machined power screw sleeves, which connect the four members and the power screw together. The manufacturability of the proposed Toggle jack lowers the cost of production.

See Also: 7 Hydraulic Jack Related Mechanical Projects Report Download

INTRODUCTION

The most basic Toggle jack design is truly engineering at its finest. With the power to magnify input forces, Toggle jacks allow us to raise vast loads using only a fraction of the force ordinarily needed. Our goal in this project is to design an efficient Toggle jack capable of raising a 10000N load. As a screw-driven mechanical system, the jack will be manually operated and have at least 7 inches under load. The design will be transportable and storable, have a removable crank handle, and operate with a factor of safety of n = 5 using standard mechanical design methods for all components. The design itself has gone through multiple stages of development. We have taken several possible failure modes into account and are confident that our design is efficient and safe.

Catia Model Of Toggle jack

SPECIFICATION

The Toggle jack design, shown in Figure 1, consists of four main lifting members, eight connection members, a power screw. Members 1 to 8 are all primarily bar shapes with ideal pin connections. Members 10 and 12 both have additional details to account for the contact surfaces. The power screw is double threaded with a collar at the member 12 connection. All members are EN8(C40) steel.

Components used in the fabrication of Toggle Jack:-

a) Power Screw

b) Nuts

c) Top plate

d) Base plate

e) Links

f) Pins

g) Spanner

Power screw

A power screw is a drive used in machinery to convert a rotary motion into a linear motion for power transmission. It produces uniform motion and the design of the power screw may be such that. Either the screw or the nut is held at rest and the other member rotates as it moves axially. A typical example of this is a screw clamp. Either the screw or the nut rotates but does not move axially. A typical example for this is a press. Other applications of power screws are jack screws, lead screws of a lathe, screws for vices, presses etc. Power screw normally uses square threads but ACME or Buttress threads may also be used. Power screws should be designed for smooth and noiseless transmission of power with an ability to carry heavy loads with high efficiency.

DESIGN AND FABRICATION OF TOGGLE JACK

Conclusion :

Our proposed design is similar to common Toggle designs in some aspects, but also advantageous in others. Similar to others, our proposed design can safely raise a load of 10000N to the required heights with relative ease on the user. Unique to our design, however, is the manufacturability of our design, which is much simpler. Since only Bar-shapes are utilized, bulk material can be more efficiently purchased and used. Also, less machining is required since there are no complex sleeves for the power screw. Only simple attachments which can be welded on are proposed. Therefore, when compared to similar Toggle jack designs that perform equally as well, our proposed design is recommended for its manufacturability and lower cost with high efficiency.

DESIGN AND FABRICATION OF PORTABLE PNEUMATIC FUEL PUMP

ABSTRACT

This project“DESIGN AND FABRICATION OF PORTABLE PNEUMATIC FUEL PUMP” is an outcome of basic instinct to increase the discharge rate and decrease the time of pumping the fuel from storage barrels to the machine or equipment especially industries where machineries are placed in second or third floor.

By utilizing simple pneumatic mechanism, fuel can be pumped especially with less power consumption and minimum human labour. When compared to traditional fuel pumping the time taken is also dramatically reduced, as the discharge rate is increased drastically.

Added advantage in this is portable and occupies less space. It is ideal for fuel pumping, as no electric field around the fuel pumping area.

This project is of great use to companies where pumping of fuel is everyday duty, even this project can be used in ration shops.

PROJECT OVERVIEW

In the pursuit of excellence, the manufacturing industries are seeking now in a new technology to improve productivity, quality of the product and reduce product cost. The cited subjects are seriously discussed in these days.

Most of the manufacturing industries use centrifugal pumps for pumping fuel from barrels to the required location. The discharge rate of centrifugal pump is low. The discharge head has also some limitations which restrict the use of centrifugal pump where high head is required.

As a fuel pump, the centrifugal pump is always risky because of electric motor placed just behind the impeller, which may lead to fire accidents.

Hence having this in mind, usage of reciprocating pump instead of centrifugal pump looked like the best alternate. Rather than keeping the idea in mind we brought it to reality. We tested the performance of both the pumps.

In this work a double acting reciprocating pump is used as fuel pump.

PARTS OF THE FUEL PUMP

The following are the parts of the fuel pump,

Pressure gauge
Air adjustment screw
Cylinder
Suction pipe
Filter
Air hose
Locknut
Grease nipple
1/4 inch gate valve
O Rings
Cylinder head
Tube couplers

DESIGN AND FABRICATION OF PORTABLE PNEUMATIC FUEL PUMP

WORKING PRINCIPLE

Initially starting with air compresses, its function is to compress air from a low inlet pressure (usually atmospheric) to a higher pressure level. This is an accomplished by reducing the volume of the air.

Air compressors are generally positive displacement units and are either of the reciprocating piston type or the rotary screw or rotary vane types. The air compressor used here is a typically small sized, two-stage compressor unit. It also consists of a compressed air tank, electric rotor and pulley drive, pressure controls and instruments for quick hook up and use. The compressor is driver by a 10HP motor and designed to operate in 145 – 175 PSI range. If the pressure exceeds the designed pressure of the receiver a release value provided releases the excesses air and thus stays a head of any hazards to take place.

The stored air from compressor is passed through an air fitter where the compressed air is filtered from the fine dust particles. However, before the suction of air into compressor a filter process take place, but not sufficient to operate in the circuit here the filter is used.

Then having a pressure regulator where the desired pressure to the operated is set. Here a variable pressure regulator is adopted.

Through a variety of direction control value are available, a hand operated solenoid Valve with control unit is applied.

The solenoid valve used here is 5 ports, 3 positions. There are two exhaust ports, two outlet ports and one inlet port. In two extreme positions only the directions can be changed while the Centro ore is a neutral position and no physical changes are incurred.

The 2 outlet ports are connected to an actuator (Cylinder). The pneumatic activates is a double acting, single rod cylinder. The cylinder output is coupled to further purpose. The piston end has an air horning effect to prevent sudden thrust at extreme ends.

ADVANTAGES

Even if all the other pumps are similar in use the Pneumatic water pump is more advantageous than the other pumps.

1.This is of compact in size

2.Less Maintenance is enough

3.The oil or water pumped is of higher pressure

4.Quite running and smooth operation is achieved.

5.Higher efficiency

6.Full efficient positive displacement pump

7.Effective working principle

8.It does not have any Prime mover, like electric motor related to the unit.

9.As the air is freely available, we can utilize the air to pumping the water and hence it is economical.

10. Less Maintenance

LIMITATIONS

1.It is costlier than the other types of pump because of compressor unit.

2.Less efficiency when compressed to other device.

3.Leakage of air affects the working of the unit.

DESIGN AND FABRICATION OF PNEUMATIC DRILL JIG FOR REDUCING LEAD TIME

ABSTRACT

Our project is based on the need for the work holding devices. This design and fabrication which will enable the operation like drilling, reaming, tapping process easier. Our project is mainly composed of design and fabrication of the“PNEUMATIC DRILL JIG” which cover the absolute design to the specified dimensions of the work piece. This box jig is economical means to produce

This pneumatic drill jig is provided with pneumatic clamping arrangement. This type of clamping arrangement saves the setting time, marking time, punching time etc. when compressed air is taken from a convenient medium to provide pope clamping force and good gripping to the component. As the quantity to produce is large the proposed pneumatic drill jig fulfills the mass production requirement in the shop. Clamping can be done by releasing the pressured air using valves.

The component is placed in between the Jig plate and the locator, which is on the piston rod. When the valve is opened, the compressed air from the compressor will enter into the cylinder through a hole at the bottom of the cylinder. The piston inside the cylinder is made to push in the upward direction. When the piston moves the locator clamps the component rigidly. Now the component is ready for drilling operation.

When the two-way valve is closed the piston will return to bottom position to release the clamps. When we close the valve, the piston will come in very high force in downward direction. So these are chances for the damage of piston. To avoid this, we are using FLOW CONTROL VALVE to control the flow of piston. This can be repeated with the same procedure as described above.

DESIGN AND FABRICATION OF PNEUMATIC DRILL JIG FOR REDUCING LEAD TIME

ADVANTAGES:

It eliminates the individual marking, positioning and frequent checking.
The operation time is reduced due to increase in speed, feed and depth of cut because of high clamping rigidity.
It is very much useful in mass production.
It makes possible to employ unskilled or semi skilled operator to make savings in labor cost.
It partially automates the tools.
It reduces the expenditures on quality control of machine parts.

LIMITATIONS:

It is only used for small size components.
Forces causing deflection may come from handling

What Is Honing Machine Process used For Super Surface Finishing

Honing is a finishing process, in which a tool called hone carries out a combined rotary and reciprocating motion while the workpiece does not perform any working motion. Most honing is done on internal cylindrical surface, such as automobile cylindrical walls. The honing stones are held against the workpiece with controlled light pressure. The honing head is not guided externally but, instead, floats in the hole, being guided by the work surface . It is desired that

1. honing stones should not leave the work surface
2. stroke length must cover the entire work length.

In honing rotary and oscillatory motions are combined to produce a cross hatched lay pattern as illustrated in Fig

Honing tools and Honing Operations

Honing is an operation that is used primarily to improve the surface finish of holes produced by processes such as boring, drilling, and internal grinding.

The honing tool consists of a set of aluminum oxide or silicon-carbide bonded abrasive sticks, usually called stones (Fig. ). They are mounted on a mandrel that rotates in the hole at surface speeds of 45 to 90 m/min, applying a radial force. The tool has a reciprocating axial motion, which produces a crosshatched pattern on the surface of the hole.

The stones can be adjusted radially for different hole sizes. Oil- or water-based honing fluids generally are used to help flush away the debris. Honing is also done on external cylindrical or flat surfaces and to manually remove sharp edges on cutting tools and inserts.

The quality of the surface finish produced by honing can be controlled by the type and size of abrasive used, the pressure applied, and speed. A fluid is used to remove chips and to keep temperatures low. If not performed properly, honing can produce holes that are neither straight nor cylindrical, but rather in shapes that are bell mouthed, wavy, barrel shaped, or tapered.

The honing stones are given a complex motion so as to prevent every single grit from repeating its path over the work surface. The critical process parameters are:

1. rotation speed

2. oscillation speed

3. length and position of the stroke

4. honing stick pressure

With conventional abrasive honing stick, several strokes are necessary to obtain the desired finish on the work piece. However, with introduction of high performance diamond and cBN grits it is now possible to perform the honing operation in just one complete stroke. Advent of precisely engineered microcrystalline cBN grit has enhanced the capability further. Honing stick with microcrystalline cBN grit can maintain sharp cutting condition with consistent results over long duration.

Advantages:
The workpiece need not be rotated by power, there are no chucks, faceplates, or rotating tables needed, so there are no chucking or locating errors.
The hone is driven from a central shaft, so bending of the shaft cannot cause tapered holes as it does when boring. The result is a truly round hole, with no taper or high or low spots, provided that the previous operations left enough stock so that the hone can clean up all the irregularities.
Honing uses a large contact area at slow speed compared with grinding or fine boring, which use a small contact area at high speed. Because of the combined rotating and reciprocating motion used, a crosshatched pattern is created which is excellent for holding lubrication. Diameters with 0.001 to 0.0001 inch and closer accuracies can be honed by using diamond stones similar to diamond wheels.
Limitations:
Honing is though of as a slow process. However, new machines and stones have shortened hone times considerably.
Horizontal honing may create oval holes unless the work is rotated or supported. If the workpiece is thin, even hand pressure may cause a slightly oval hole.

PROBLEM STATEMENT

Lathe is suitable for operations like turning, boring, facing taper turning, thread cutting, knurling, etc. but not suitable for operations like key way cutting etc. Because in a conventional lathe as soon as the machine is switched on, the workpiece fixed to the chuck rotates. This is a major limitation of the conventional lathe keeping in view of the present project work.

Gear cutting is a specialized form of milling, and the lathe is quite suited to this job for smaller work (6" diameter or so) with the help of attachment.

INDEXING

Indexing is an operation of dividing the periphery of a piece of work into any number of equal parts, for e.g. this operation can be adopted for producing hexagonal and square headed bolts, cutting spines on shafts, fluting drills and in gear cutting. All these works require a holding device which will permit the rotation of the work about the axis so that periphery of the work piece can be divided equally and accurately. Such a work holding devices is known as DIVIDING HEAD OR INDEXING HEAD.

Laser cutting
Incremental sheet forming etc.

Sheet Rolling machine

Roll bending

A continuous form from of three-point bending is roll bending, where plates, sheet and rolled on each end, one of the support can often be swung clear to permit the removal of closed shapes from the rolls shapes can be bent to a desired curvature on forming rolls. These machines usually have three roll in the of a pyramid, with the two lower rolls being driven and the position of the upper roll being adjustable by a frame.

DESCRIPTION OF THE MACHINE

The Sheet Metal Rolling Machine works according to the principle of three point bending. The rotation of the driven rolls being utilized to feed the metal through the rolls by means of the frictional forces present between the surface of the rolls and sheet. No lubricant is used at its presence interference with the ability to grip. Sheet Metal Rolling Machine essentially consists of three rollers, used to manufacture circular components like cylinders. Sheet Metal Rolling Machine is classified into two types based on the arrangement of the rollers.

They are as follows.

1. Pinch type machine

2. Pyramidal type machine

This machine is of pinch type here only the top roll serves as a driven, bottom roller are idler and rotates on friction with the work metal blank.

WORKING PRINCIPLE

The Sheet Metal, which is to be formed in cylindrical shape, is present atm the edge by hammering. To start the operation easily and to avoid flats at the beginning and at the ends of the rolled form. In rolling cylindrical shapes a gradual curve is to be put in the metal rather than sharp bends. Now the sheet metal is introduced between the top and the bottom rolls, the gap between the top and bottom rolls are adjusted as per the required diameter by regulating the screw rods.

The rollers were arranged in triangular form; two sets of rollers below and one above. The upper roller provide the bending force while the back base roller provides the required driving force and the front end Roller bends the metal according to set radius of bend. Aperture adjuster on each block assembly ensure loading of workpiece and adjustment to required radius of bent. The free end of the top bearing block is spring loaded to increase or to reduce top-base roller clearance. Two other bores on each bearing blocks provide an adjustment for the roller gap variability. Top roller Provides the bearing load (bending force)and also compliments the driving roller when working on thick materials.

The lower back roller provides the necessary driving forces while the idler roller does the bending and material delivery. There are two crank levers, one on the top roller and another on the front end

roller. The lever (handle) coupling head has a square configuration which fits into the square end of the roller shaft.

The frame structure made of(50×50×5)mm angle iron for the purposes of strength. The tool table is provided below the rollers for safe keeping of tools and cranks. The roller head assembly is detachable from the frame and can be mounted on a table to be used as a table top machine for tinkering works.

DESIGN AND FABRICATION OF PNEUMATIC LIFTING TABLE

ABSTRACT

The rod connected with the piston pushes the zig-zag frame so that the lift moves up. When the other ball valve is opened, the air inside the cylinder is released. Therefore the lift comes down.

Introduction:

A hydraulic fluid power system is defined as a means of power transmission in which relatively in compressible fluid is used as the power transmitting media. The primary purpose of pneumatic system is the transfer of energy from one location to another location and this energy into useful work.

In this project of the fabricated model of will describe the working principles as well as hydraulic machines application and its advantages. Efforts have been taken to show the path of hydraulic fluid as it is applied and released. The system pressure can be generated in the form of any physical action which result a compression over the pneumatic pressure which is developed in the form of air compressing externally can be applied to activate system. There is a constant relation between pressure density, and volume, According to Bernoulli’s equation.

Source DESIGN AND FABRICATION OF PNEUMATIC LIFTING TABLE

Lift tables are used to raise and position work pieces for ergonomic access. They are used for material positioning, load positioning, or lifting. This lifting has a pneumatic power source and is safe for heavy paint applications and other hazardous locations. This lift comes with alternative power sources

CONSTRUCTION AND WORKING

This project is developed for the users to lift any weight using air pressure. High pressure air is stored in a tank. A cylinder with piston arrangement is connected with a zig-zag pattern. Two pipes connected with ball valves connect the air tank with the cylinder. When one valve is opened, the air rushes out into the cylinder. Therefore the piston moves in one direction. The rod connected with the piston pushes the zig-zag flame so that the lift moves up. When the other ball valve is opened, the air inside the cylinder is released. Therefore the lift comes down. The main objective of Zig-Zag Pneumatic Lift project is developing a lift system for lifting any weight using air pressure.

In this project, we stored high pressure air in a tank. A zig-zag pattern is connected with a cylinder with piston arrangement.

The cylinder and the air tank are connected by the two pipes with ball valves. When one ball valve is opened, the high pressure air will enter into the cylinder. Hence, the piston will move in one direction. The rod connected with the piston pushes the zig -zag frame so that the lift moves up. When we open the other ball valve, the air inside the cylinder is released. So, the lift comes down.

Low Cost Automation Sensor Based Continuous Cut-Off Machine | Automation In Cut-off Machine Project

In the process of production of any components from steel bar stock , the preliminary process is that of cutting-off of bar stock to length according to the finished size requirements of work piece. This process is normally done by an power hacksaw machine.

The sequence of operation is as follows:

1.Feed bar stock to stopper that is set according to length of work piece to be cut.

2. Clamp the bar stock

3. Feed the cutter blade to cut the required length.

4, Retract the cutter

6. De-clamp the work piece

Introduction Of Electro Hydraulic Forming | Advantages And Application

Electro Hydraulic Forming is type of high energy rate forming processes

Electrohydraulic forming is a type of metal forming in which an electric arc discharge in liquid is used to convert electrical energy to mechanical energy and change the shape of the workpiece. A capacitor bank delivers a pulse of high current across two electrodes, which are positioned a short distance apart while submerged in a fluid (water or oil). The electric arc discharge rapidly vaporizes the surrounding fluid creating a shock wave. The workpiece, which is kept in contact with the fluid, is deformed into an evacuated die.

HIGH ENERGY RATE FORMING PROCESSES

The parts are formed at a rapid rate, and thus these processes are also called high – velocity forming processes. There are several advantages of using these forming processes, like die costs are low, easy maintenance of tolerances, possibility of forming most metals, and material does not show spring-back effect. The production cost of components by such processes is low. The limitation of these processes is the need for skilled personnel.

There are three main high energy rate forming processes: explosive forming, magnetic forming, and electro hydraulic forming. We shall discuss these processes.

Electro Hydraulic Forming

Electro hydraulic forming (EHF), also known as electro spark forming, is a process in which electrical energy is converted into mechanical energy for the forming of metallic parts. A bank of capacitors is first charged to a high voltage and then discharged across a gap between two electrodes, causing explosions inside the hollow work piece, which is filled with some suitable medium, generally water. These explosions produce shock waves that travel radially in all directions at high velocity until they meet some obstruction. If the discharge energy is sufficiently high, the hollow work piece is deformed.

Electro Hydraulic Forming

Principle

A sudden electrical discharge in the form of sparks is produced between electrodes and this discharge produces a shock wave in the water medium. This shock wave deforms the work plate and collapses it into the die.
The characteristics of this process are similar to those of explosive forming. The major difference, however, is that a chemical explosive is replaced by a capacitor bank, which stores the electrical energy.
The capacitor is charged through a charging circuit. When the switch is closed, a spark is produced between electrodes and a shock wave or pressure pulse is created. The energy released is much lesser than that released in explosive forming.

Process Characteristics:

i) Stand off distance: It must be optimum.

ii) Capacitor used: The energy of the pressure pulse depends on the size of capacitor.

iii) Transfer medium: Usually water is used.

iv) Vacuum: the die cavity must be evacuated to prevent adiabatic heating of the work due to a sudden compression of air.

v) Material properties with regard to the application of high rates of strain.

Limitations:

i) Suitable only for smaller works

ii) Need for vacuum makes the equipment more complicated.

iii) Proper SOD is necessary for effective process.

Advantages of EHF

A single-step process (rather than progressive stamping)
Fine details and sharp lines can be easily formed
Forming of male and female shapes (negative and positive)
Only a single one-sided die is required
Enables extremely deep forming (much more than is possible with conventional stamping)
Even distribution and higher strength of thin material
Extremely fast
Equipment has small footprint
No need for a press – the forming chamber is a self-balanced system
Allows forming of parts up to a few square meters in size.

Accuracy of parts produced

Accuracy of electro hydraulically formed parts depends on the control of both the magnitude and location of energy discharges and on the dimensional accuracy of the dies used. With the modern equipment, it is now possible to precisely control the energy within specified limits, therefore the primary factor is the dimensional accuracy of the die. External dimensions on tubular parts are possible to achieve within ± 0.05 mm with the current state of technology.

Applications:

They include smaller radar dish, cone and other shapes in thinner and small works.

PNEUMATIC POWER STEERING MECHANICAL PROJECT

Introduction

Power steering systems have contributed to reduced driver fatigue and made driving a more pleasant experience. Nearly all power steering systems at the present time use fluid pressure to assist the driver in turning the front wheels. Since driver effort required to turns the front wheels is reduced, driver fatigue is decreased. The advantages of power steering have been made available on many vehicles, and safety has been maintained in these systems.

There are several different types of power steering systems, including integral, rack and pinion, hydroboost, and linkage type. In any of these systems, the power steering pump is the heart of the system because it supplies the necessary pressure to assist steering.

The power steering pump drive belt is a simple, but very important, component in the power steering system. A power steering pump in perfect condition will not produce the required pressure for steering assist if the drive belt is slipping.

Integral power-assisted steering system

In the integral power-assisted steering system, the pump is bolted to a bracket on the engine, and the recirculating ball steering gear is mounted on the frame beside the engine. This type of steering system is used on many rear-wheel-drive cars and light-duty trucks. The pump is driven by a belt from the crankshaft and an integral reservoir is mounted on the pump. A high-pressure hose and a return hose are connected from the pump to the steering gear

POWER STEERING

Introduction

Pneumatic machinery are machines and tools which use air power to do work. Heavy equipment is a common example. In this type of machine, high pressure Compressed air is transmitted throughout the machine to various Pneumatic motors and Pneumatic cylinders. The air is controlled directly or automatically by control valves and distributed through hoses and tubes.

Scope objective

The popularity of Pneumatic machinery is due to the very large amount of power that can be transferred through small tubes and flexible hoses, and the high power density and wide array of actuators that can make use of this power. These machinery are based on the Cylinders, Compressor and Pump.

Working

Pneumatic cylinders are pressurized by Pneumatic pressure and get their power for the Pneumatic air under pressure. They transform the air’s energy to linear work. A Pneumatic cylinders works in a Pneumatic system and is the motor side of this system. The generator side of the air Pneumatic system is the pump or Compressor that brings a fixed or regulated air flow into the system. The Pneumatic cylinder initiates the pressure of the air, which can never be larger than the pressure that is asked by the load. The cylinder consists of a cylinder barrel, in which a piston connected to a piston rod is moving. The barrel is closed by the cylinder bottom at the bottom side and by the cylinder head at the side where the piston rod comes out of the cylinder. Mounting bracket or clevises are mounted to the cylinder bottom as well as the piston rod. The piston has sliding rings and seals. The piston divides the inside of the cylinder in two chambers, the bottom chamber and the piston rod side chamber.

PNEUMATIC POWER STEERING MECHANICAL PROJECT

By pumping Pneumatic air to the bottom side of the Pneumatic cylinder, the piston rod starts moving out. The piston pushes the air in the other chamber back to the air reservoir. If we assume that the air pressure in the piston rod chamber is zero, the pressure in the cylinder is now Force/Piston area.

If the air is pumped into the piston rod side chamber and the air from the piston area flows back to the air reservoir without pressure, the pressure in the piston rod area chamber is Load/(piston area - piston rod area). In such a way the Pneumatic cylinder can push and pull.

When the vehicle weight increases, the power required to steer the vehicle also increases. Most of the vehicles are have fluid power for steering.

In this project pneumatic power (compressed air) is used in place of Mechanical power.

Application

1.Used in all light duty vehicles like cars

Expected outcome

1.Very easy to drive vehicle than fluid power.

2.No moving parts.

3.Easy maintenance.

4.No separate drive is required to drive the compressor as the brake system has the compressed air for operation.
