Design and Fabrication of Automatic Pneumatic Ramming Machine

Abstract

This project is a study about the design and fabrication of automatic pneumatic ramming machine, which shows the capability to design a concept using variety of components. As the name implies, pneumatic systems use pressurized gases to transmit power. Typically, pneumatic systems use air as the fluid medium, because it is low cost, safe and easily available fluid. The automatic pneumatic ramming machine is designed using various components. The components are MS Frame, MS Plate, Air Compressor, Solenoid Valve, Timing Control Unit, Pneumatic Cylinder and Ramming Box, The pneumatic cylinder is used to obtain the ramming action. The pneumatic rammer used for ramming the sand uniformly and plastic water bottles folding around the pattern has wide applications in small scale industries. To operate this rammer, an air compressor is required. For the operation of ramming a butt is attached to the bottom of the piston rod. In this project, the solenoid valve is used as a direction control valve. This solenoid valve management is led by the electronic control timing unit. The compressed air passes through the pneumatic double acting cylinder. The ram is fastened at one end of the pneumatic cylinder. The compressed air pushes the pneumatic cylinder in order that the piston moves downward by giving air supply in one direction of the pneumatic cylinder. The solenoid valve changes the airflow in the opposite way by the small-time delay. Due to the changing of the airflow direction, the pneumatic cylinder piston moves upward in this time. This airflow direction is controlled by the solenoid valve
