— The pneumatic system has gained a large amount of importance in last few decades. Pneumatic is vastly
used in transmission of energy. It is basically a science of compressed air. However, till now it has developed its scope in
a wider area & succeeded over conventional power transmission method. This importance is due to its accuracy and
cost. This convenience in operating the pneumatic system has made us to design and fabricate this unit as our project.
This project will focus on build of low force punching tool with using a pneumatic System. It is because, in the real
industry, most company needs to buy a hydraulic machine whether they only need a small force to punch. Whether
hydraulic machine can used for low or high force, high cost of machine and maintenance are needed. Therefore, this
pneumatic punch also can help small company to use semi auto puncher than using manual puncher. The paper implies
principle of converting pendulum movement of toggle by applying air pressure into linear motion of ram with suitable
linkage for the operation. It works on the principle of compressed air. The compressed air with a pressure of 4-6 bar
passing through the punching machine and the punch will be done. The material is sheared to the required profile of the
punch and blank is moved downwards through the die clearance. For alternate operation of air in the ports we are using
the 5/3 direction control valve. Pneumatic toggle press is mainly use for operations on sheet metal such as piercing,
riveting, stamping, clinching, etc. This machine is used in mass production and more efficient way to form metal into
finish product.
