Pneumatic punch clutches generally use composite dry pneumatic clutches. The flywheel has built-in bearings and clutches, and the sealing plate is fixed and combined. When the start control button is pressed, the solenoid valve presses the air into the clutch and transmits the power of the flywheel to the crankshaft for work. Select the kinetic energy button of the control panel to achieve safe movement and continuous stroke work.The slider of the pneumatic punch is a connecting rod and the ball head adjustment screw to transform the circular motion of the crankshaft into reciprocating motion. The ball head screw can adjust the clamping force and cooperate with the adjustment of the height of the mold. The lower end of the slider is made of a mold shank hole, which can be fastened during decoration. The mold can be fastened. Large molds can use template holes on both sides. The slider adjustment hole is equipped with a return device, and the ejector seat on both sides can be adjusted according to the height of the mold to achieve automatic discharge.
