Main features of pneumatic power press

  1. The pneumatic power press features fine steel plates welded machine body, tempering treatment (or vibration relief), shot blasting, rigidness, accuracy and stability.
  2. Vertical located crank shaft, compact structure; the crank shaft undergoes grinding treatment after high frequency quenching, which has a good smooth finish and rotates flexibly; lengthened rectangle hex guide-way with a surface of bronze plate, which has high guide accuracy.
  3. Pneumatic dual balance cylinder, balanced sliding block and punch weight, which reduce impact and noise, eliminate the clearance between connecting rod and sliding block, reduce the impact and wear of the stress parts.
  4. The whole machine adopt PLC centralized control. The gas circuits adopt imported safety dual-valve, which can achieve jog, inch, single and continuous punching.
  5. The key parts such as sliding block, guide-ways, worktable plate, connecting rod, and are all castings made of resin sand, which improved the surface roughness 1-2 level, and improve the size accuracy 2-3 level.
  6. The 60T-level machines adopt the electrical control device to adjust the die height. Fine configuration, the key parts like pneumatic components, electrical components, sealing parts, buttons and etc all adopt imported parts.



Pneumatic steel punch machine uses the high pressure gas generated by the compressor and deliver it to the solenoid valve through the pipeline, controlling the function of solenoid valve by the foot switch thus control the working of the air cylinder to achieve the purpose of punching. The compressed air can be stored in the air tank and used at any time, it can avoid energy waste during the idling time. Using the cylinder as the working part and the solenoid valve as the control element make the machine structure simpler, with low failure rate, high safety, simple maintenance, lower maintenance cost and high production efficiency.
