INTRODUCTION

This project is about cutting the wood, metal, pipe, angle, channel, flat plates, rods and such other things.

It is very simple mechanism but very useful to produce the many type of component in less time. The main advantage of project is produce four part in single time.

ELEMENTS

HACKSAWELECTRIC MOTORMODEL FRAME

HACKSAW

A saw with a narrow fine-toothed blade set in a frame, used especially for cutting metal. They can also cut various other materials, such as plastic and wood.

TYPES OF SAW

Coping saw Tenon saw Rip-saw

COPING SAW

Coping saws are used to remove complicated shapes and cut curves in wood and plastic.

TENON SAW

Tenon saws are used to make straight cuts in wood and occasionally some plastics.

RIP-SAW

Large panels or sheets of materials, for example plywood or MDF, require larger ripsaws in order to cut them by hand.

Ripsaws are used to cut along the grain of large panels of real timber.

ELECTRIC MOTOR

An electric motor is an electrical machine that converts electrical energy into mechanical energy.

MODEL FRAME

Model frame is the main supporting structure of the model to which all the component are attached.

SCOTCH YOKE MECHANISM

The Scotch yoke is a reciprocating motion mechanism, converting the linear motion of a slider into rotational motion, or vice versa.

WORKING

Working principle of hacksaw machine is very

simple.it works on scotch yoke mechanism. First of

all the hacksaw machine is put on ground and after

that the whatever metal , wood, pvc, is cut is fixed

on vice at required length, after that the electric

motor is connect with electricity.

Now start the electric motor so due to that the shaft of motor and hollow disc will be rotate and also rotate the eccentric center and link connect to it.

Due to rotation of links the hacksaw frame will be reciprocate on the metal and cutting of metal is done.

ADVANTAGES

Weight of machine is less. It reduce the work of labor. Easy to make because of simple construction. High production rate. Cost is less.

DISADVANTAGES

Time consume more.Speed variation is required for cutting the

different metal.

APPLICATIONS

In engineering industry.In construction industry.In workshop

CONCLUSION

We learnt how the theoretical design is possible in practical. Other hacksaw machine is only cut one part at one time but this machine cut the four part at a time, this hacksaw machine has lighter weight compare to other machine. The cost of machine is less and easy to operate so it affordable for all industry.

FUTURE SCOPE

We try to change the speed of motor for cutting the different metal at various speed if it possible.
