FOUR WAY HACKSAW

Abstract

This project is developed for the users for pneumatic hacksaw machine. It consists of pneumatic cylinder, piston, air tank, solenoid valves, gate valve, timing control, hacksaw, vice etc. A non-return valve is fixed with the air tank so that the user can add compressed air in the air tank. An air gauge is connected with the air tank to display the air pressure in the tank. The delivery hose is connected to the cylinder through a solenoid valve. Another solenoid valve is connected with the cylinder for releasing the air pressure in the returning stroke. The two solenoid valves are alternatively energized by timing control. When the first valve is opened, the compressed air pushes the piston and when the second valve is opened, the air pressure is stopped and due to the force of restoring spring, the piston comes back. Thus an alternative linear movement is produced. The hacksaw is connected with the other end of the piston. The work piece is kept using the vice with auto gear motor attachment.
