Fabrication of Four Way Hacksaw Machine by Using Radial Crank Mechanism

Abstract

The aim of present work is to fabricate a new high speed 4-Way Hacksaw Machine, to automate and modify the conventional power hacksaw machine in order to achieve high productivity of work pieces than the 1-way power hacksaw machine using crank mechanism. This machine is built with the 4 hacksaw machines such that all the machines are operated simultaneously with the help of a Motor and Radial Cam Mechanism

There are many industrial applications where round or square bars are required to be operated on different machines to make machine components such as Shafts, Bolts, and Screws etc. This needs more number of pieces to be cut for mass production of those components. Four-way hacksaw machine is basically a cutting device, which cut in four directions at a same time. A hacksaw is a fine–toothed saw, originally made principally for cutting metal. They can also cut various other materials, such as plastic, wood and steel etc. This paper proposes the prototype model of four-way hacksaw machine which can cut four pieces simultaneously without any jerk and minimum vibrations. The prototype model implies conversion of rotary motion into the reciprocating motion for proper working of hacksaw. In present condition many electrically operated power hacksaw machines. The hacksaw is a metal cutting machine tool designed to cut multiple metals simultaneously by applying cam mechanism. The operation of the unit is simple to a few simple operations involving a motor and simple mechanism. There are numerous types of cutting machines in Engineering field, which are used to fulfil the requirements.
