JH21-200T punch press machine for sale

JH21-200T punch press machine for sale, CNC punching machine manufacturers. The pneumatic punching machine uses the high-pressure gas generated by the compressor to deliver the compressed gas to the solenoid valve through the pipeline, and controls the action of the solenoid valve through the foot switch to control the work and return of the cylinder, so as to achieve the purpose of punching.

Technical principle

Compressed air can be stored in the air storage tank and can be used at any time, so the motor has no energy waste of idling. The cylinder is used as the working part and the solenoid valve is used as the control element, so that the structure of the machine is simpler, the failure rate is low, the safety is high, the maintenance is simple, the maintenance cost is lower, and the production efficiency is high. The 220V power supply is used to realize the control of the solenoid valve, and the operation is simple and convenient.

●The machine features fine steel plates welded machine body, tempering treatment (or vibration relief), shot blasting, rigidness, accuracy and stability.

●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 guideway with a surface of bronze plate, which has high guide accuracy.

●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 impactand wear of the stress parts.

●The whole machine adopt PLC centralized control. The gas circuits adopt imported safety dualvavle, which can achieve jog, inch, single and continuous punching.

●The key parts such as sliding block, guideways, 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.

●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.
