Objective The objective of this project is to design and fabricate a model of double acting hacksaw machine . There are numerous types of cutting machines in engineering field. To satisfy the needs of the industries we have designed a machine. Abstract In this project we design a double acting hacksaw machine. which are used to fulfill the requirements . scotch-yoke mechanism is used in this project.This new machine is used to avoid energy loss and save time. The machine is exclusively intended for mass production and they represent fast and more effective way to cut a pipe. In industries saving the time and man power is an important thing all over the world. . . This project employs the Scotch yoke mechanism in power hacksaw machine which enables it to cut two components at a time thereby improving the productivity.Introduction Increasing the productivity is one of the main requirements of production engineering in any kind of manufacturing industry. Either by reducing the operation time or by improving the capability of the machine to produce the components in an increased number at the same time is very essential for an industry to achieve the same. LAYOUT . If the motor is turned on the pulley is getting rotating motion .MECHANISM This project is worked under by the scotch yoke mechanism. The hack saw connected to the each shaft at the end. The scotch yoke mechanism convert the rotary motion into the reciprocating motion. The clamp is fixed with the two shaft at the two end The each shaft is act the reciprocating motion through the each shaft. The machine has the prime mover at the bottom of the machine The pulley is attached to the body at the top and the end of the side portion The pulley is connected with the disc type plate The pulley and the disc has separate connection with the one small metal rod through the bearing The motor and pulley is connected with one V-type belt The clamp is fixed with the disc. CAD DRAWING . this wheel 1 is connected with belt driven wheel 2. This movement of hacksaw is used to cut the work pieces. Electrical motor is transfer the reduced rotational force to flywheel through the belt driven wheels. The flywheel is mounted with belt driven wheel 2. These wheels also used to give reduced and correct speed to the fly wheel mechanism. Electrical motor is directly connected with belt driven wheel 1. This flywheel is connected with hacksaw through some mechanical arrangement. The fly wheel mechanism will give operating force to the hacksaws. Belt driven wheels are connected with electrical motor to drive the system. . Fly wheels and two belt driven wheel is used in this project.WORKING In this project one electrical motor is used to drive the system. This flywheel mechanism will give the front and back horizontal movement to the hacksaw through mechanical arrangement. 1080 3. gas cutting cost Labour cost = Rs. drilling.1400 2.5400 Overhead Charges = 20% of the manufacturing cost = Rs. LABOUR COST: Lathe.6480 Total cost for this project = Rs. TOTAL COST: Total cost = Material Cost + Labour Cost + Overhead Charges = 4000 + 1400 + 1080 = Rs. power hacksaw. OVERHEAD CHARGES: The overhead charges are arrived by “manufacturing cost” Manufacturing Cost = Material Cost + Labour Cost = 4000 + 1400 = Rs. welding.7000 .COST ESTIMATION 1.
