Product Description


JH21-45 CNC Carbon/Stainless Steel Metal Foil Pneumatic Power Punch Machine

Product Description:

The Pneumatic Punching Machine is a high-performance automatic punching machine designed to provide adjustable stroke length with low noise and vibration levels. It also features a high punching accuracy with a PLC electrical control system. The machine is equipped with an air cushion to ensure a smooth operation and reduce vibration. The Pneumatic Punching Machine is the perfect tool for a wide variety of applications including industrial production, maintenance, and repair.



Pneumatic punch press is mainly composed of body, pneumatic clutch, slider and micro-control system.

1. Body: It is casted together with the workbench. The slider reciprocates up and down in the guide rail on the pneumatic punching machine body. The gap between the guide rail and the slider is adjusted by the top wire, and it is tightened after adjustment.

2. Clutch: The composite dry pneumatic clutch is adopted. The built-in bearing of the flywheel is fixedly combined with the clutch and the sealing plate. When the start control button is pressed, the air is pressed into the clutch by the solenoid valve, and the power of the flywheel is transmitted to the crankshaft for work. The kinetic energy of the control panel is selected. The key can realize inching safety and stroke continuous work.

3. Slider: The connecting rod and the ball head adjustment screw convert the circular motion of the crankshaft into a reciprocating motion. The ball head screw can adjust the clamping force and adjust the mold height. The lower end of the slider is formed by the handle hole, which can be tightened during decoration. Solid mould, large mold can use both sides of the template hole, slider adjustment hole is equipped with a material ejection device, adjust the top material seat on both sides according to the height of the mold, to realize automatic material removal work

4. Operating mechanism: controlled by a microcomputer, and the status mode is displayed on the panel. When the status bar shows inching, the machine can be started synchronously with both hands to realize arbitrarily stopping at 360 degrees. Movement, the synchronous start time is 0, 2-0, 3 seconds. When starting the safety stroke or continuous work, you must use the inch kinetic energy to point the hour hand of the display to 12 o'clock, or observe the angle table at 12 o'clock, and it can be started at plus or minus 20 degrees ; When working continuously, you must press and hold the start button with both hands to make the machine run continuously for 5-7 hours before continuous work can be achieved.
