DESIGN AND FABRICATION OF PEDAL POWERED HACKSAW

Submitted By: Ankur Goyal(10109033) Ashish Jindal(10109037) Ankit Singla(10109032)1The pedal powered hacksaw set up, has a simple mechanism, as by pedalling the wheel, rotary motion is converted into the To and Fro motion of the cutting tool (hacksaw). The rotary motion is converted in to linear motion by crank and pinion arrangement.

The size and shape of this setup is similar to cycle. It is like a cycle is added with a bed for cutting a work piece. As it required very low pedalling power it can be operated by very low power.INTRODUCTION:The principle of pedal power hacksaw, is to change circulatory motion or cycling motion into translatory motion with the help of metal connecting rod .1. The working medium adopted is Mechanical power.2. The machine work without the help of electricity.3. The Rotary motion of pedaling operation performed to our required oncutting the job.4. The work piece is clamped on the work table using suitable clampingdevice like vice.5. After clamping, by pedaling the cutting operation takes place on thework piece.6. After machining the work piece is removed and cleaned.WORKING PRINCIPLE:HACKSAW:A hacksaw is a fine-tooth hand saw with a blade held under tension in a frame, used for cutting materials such as metal or plastics. Hand-held hacksaws consist of a metal arch with a handle, usually a pistol grip, with pins for attaching a narrow disposable blade.

A screw or other mechanism is used to put the thin blade under tension. The blade can be mounted with the teeth facing toward or away from the handle, resulting in cutting action on either the push or pull stroke.

BLADES:

Blades are available in standardized lengths, usually 10 or 12 inches for a standard hand hacksaw. "Junior" hacksaws are half this size. Powered hacksaws may use large blades in a range of sizes, or small machines may use the same hand blades.

The blade chosen is based on the thickness of the material being cut, with a minimum of three teeth in the material. As hacksaw teeth are so small, they are set in a "wave" set.

HACKSAW BLADE

Handle:There are three types of Hacksaw Handle used:FABRICATION OF MACHINE:

There are few types of fabrication methods that are done on the machine. They are as follows:

Arc cutting.WeldingDrillingTurningGrindingFURTHER OPERATIONS:CleaningAssembling

MACHINING OPERATIONS:In this project it is used to cut the raw material such as plates, rod. This is done by arc cutting machine.

DRILLING:Drilling is used to produce holes in objects. In this project the pipes and plates required the holes for making assembly. These holes are done by vertical type drilling machine.

FINE GRINDING:It is nothing but a grinding process, which is done as smooth with fine grains. It is done by convention grinding machine.

WELDING:It is the process, which is used to join two, is more similar materials as well as dissimilar materials. This is done by gas welding process.

TURNING:It is used in this project to make the groove on the both sides of topcover plate. This is done by conventional lathe.

FURTHER OPREATIONS:

CLEANINGIt is the operation to clean the all machined parts without burrs, dustand chip formals. By meaning the parts they are brightened and goodlooking. ASSEMBLINGIt is the operation, its deals with the assembling of various partsproduced by above operations.DRAWINGS:

FINAL DRAWINGAPPLICATIONS OF PEDAL POWERED HACKSAW:1. In a furniture making industry at production department it is widely used.2. Cutting performs in all types of industries.3. This machine applied in carpentry shops and plumbing works.ADVANTAGES:1. No need electricity.2. More efficient3. Power can be easily transmission.4. Less loss in transmission.5. Time saving as compared to simple hacksaw6. Comfortable then ordinary hacksaw.LIMITATIONS:1. Leads to physical ill.2. High thick wood cannot be cut.3. Time consuming as compared to electrical power hacksaw.4. Not fit for heavy production.5. Its totally manually operated.6. Without human effort it is not operated.
