Design and Fabrication of Pneumatic Cutter Machine.

Abstract

Pneumatics systems are extensively used in a wide range of industries, factories and manufacturing sector entities. Pneumatics system are noted for their simplicity, reliability, and ease of operation. Also they are suitable for fast and rapid application of force. The purpose of this project is to therefore design a simple, easily operated pneumatic sheet metal cutting and bending machine that is sturdy and strong. A pressure of 8-10 bar is enough for operating the unit. The pressurized air passing through the tubes to the cylinder, forces the piston out whose power through the linkage is transmitted to the punch. The work piece thus got is for required dimensions and the piece can be collected through the land clearance provided in the die. The die used in this is fixed such that the die of required shape can be used according to the requirement. Automation of machine is achieved with the help of pneumatic system. This involves the design of an efficient system which reduces the human effort and help to increase production output. Usually the sheet metal cutting machine is manually hand operated for medium and small scale industries. The piston is connected to the moving cutting blade which his used to cut metal. This sheet cutting machine can cut sheet maximum 1 mm thickness with shearing blades which length is 375 mm and width 38 mm at a pneumatic pressure of 3 bar and its material is mild steel. The design and fabrication of pneumatic sheet cutting machine is totally economical in human effort and useful in small and medium sheet metal industries
