Product Details

Pneumatic punching machine , also known as pneumatic press, among which JH series pneumatic punching machine refers to open fixed table press, which is different from open tilting press and closed press. JH21 pneumatic punching machine has a simple structure and adopts pneumatic technology, which is more energy-saving than electric punching machine. It is easy to operate and has high safety. It uses foot switch to control the solenoid valve, which has simple structure, low failure rate and improves production efficiency. The slider of pneumatic punching machine can move in inches and can stop movement in an emergency, which is safer to operate. The air circuit adopts double valve control, which is sensitive and meets the safety standards of composite press.

Pneumatic punch production line

Most of the common open fixed table presses are open single point presses, and the main models are JH-25T, JH-45T, JH-63T, JH-80T, JH-125T, JH-160T, JH-200T, etc. Open single point fixed presses are suitable for cold stamping processes such as blanking, stamping, forming, bending, and shallow wire drawing, and are widely used in electrical appliances, vehicles, agricultural machinery, tractors, mining machinery, hardware tools, machinery manufacturing and other industrial fields.
