Pneumatic cylinder, also known as air cylinder, is a mechanical device which uses the power of compressed gas to produce a force in a reciprocating linear motion. [ 1 ] : 85 Like in a hydraulic cylinder , something forces a piston to move in the desired direction.
Blanking is the operation of cutting flat shapes from sheet metal. The outer area of metal remaining after a blanking operation is generally discarded as waste. Size of blank or product is the size of the die & clearance is given on punch. It is a metal cutting operation. In blanking, metal obtained after cutting is not a scrap if it is usable.
In the animation above, ~30 degree dies are being used to produce 90 degree bends. The air gap which remains between the lower die and the sheet metal after the bend is completed is the reason for the term "air bending". Rotary bending dies—a cylindrical shape with an 88-degree V-notch cut along its axis is seated in the "saddle" of the punch.
An air-operated valve, also known as a pneumatic valve, is a type of power-operated pipe valve that uses air pressure to perform a function similar to a solenoid. As air pressure is increased, the compressed air starts to push against the piston or diaphragm walls which causes the valve to actuate. Whether the valve opens or closes depends on ...

Pneumatic actuator operating a valve through a rack-and-pinion mechanism. [7] A pneumatic actuator is similar to a hydraulic one but uses a gas (usually air) instead of a liquid. [8] [9] Compared to hydraulic actuators, pneumatic ones are less complicated because they do not need pipes for the return and recycling of the working fluid. On the ...
