Abstract In this paper we have designed an automated
Four Way Hack-saw Machine which uses Motor, Linkages, Saw mechanism, Steel rods, etc. which are used to mount the linkages on the Hack-saw mechanism. In small scale industries the raw materials such as PVC pipes, wooden blocks, metal pieces need to cut into pieces foe various applications. For such work hack saw blade is used to cut the work-piece into desired pieces. In some industries this work is done manually by labors working there. This results in decreasing the efficiency of the industry as labors are not able to work all day in any industry. In some industry hacksaw machines are used for cutting purpose. But the biggest drawback of those machines is that only one work piece can be cut at a time on a single machine. This reduces the load on labors but is not so efficient as only one work-piece can be cut at a time. To deal with this problem we have designed a four way hack-saw machine. This machine consists of four hack-saw blades mounted in four directions. At a time four work-pieces can be mounted on the machine. We have used a D.C. motor for rotating the Cam which is linked with the Connecting Rods. The motor is used to rotate the linkages on which the hack-saw is mounted. This mechanism helps in reducing time of cutting the work-piece and also gives a better efficiency and provides safety.
Key Words: D.C. Motor, Linkages, Connecting Rods,
conversion of rotary motion into sliding motion used for cutting the tool. We are using single motor which will be centrally mounted and on which all the linkages would be connected which would help in transferring the motion to the hack-saw blade. This machine will basically do multi-purpose work at a time which will increase the efficiency of the industry and on the other hand will increase the rate of production by almost four times. It can be used in a small workshop and industry as it is available in very low price and its smaller size and high efficiency. Disc is rotated with DC motor, rotary motion of wheel is converted into the reciprocating motion of the cutting tool (hacksaw).This reciprocating notion is used to obtain the linear motion of blades and material is cut. Bed is provided for placing the work-piece to be cut.

1. INTRODUCTION:-
In small scale industries, due to more demand workers usually face huge work load and they reach a stage of fatigue. To reduce such work load industry implements new machineries. It is a conventional machining process which works on the principle of metal cutting. One motor is used for doing four number of operations at a time. The demand of hacksaw blade is considerably increasing day by day with the growth of industrialisation, engineering sector, real estate, etc. This mechanism will reduce the time required for cutting . The basic principle we are using is Š 2017, IRJET
