Features:
* 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 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 impact and wear of the stress parts. The whole machine adopts PLC centralized control, the gas circuits adopts imported safety dual valve, which can achieve jog, inch, single and continuous punching; the key parts such as sliding block, guideways, worktable plate, connecting rod and all castings are made of resin sand, which improved the surface roughness 1-2 level, and improve the size accuracy 2-3 level.
* The 60T-level machine adopts the electrical control device to adjust the die height. Fine configuration, the key parts like pneumatic components, electrical components, sealing parts, buttons etc. all adopt imported parts.
* There are optional dry or wet friction clutch, and optional hydraulic overload protection device or press-down type safety device, all of them can be equipped with automatic lubrication, photoelectric protection, frequency conversion and speed control, air blowing device and etc. according to customers' needs.
