JH21-400T CNC sheet metal punching machine

CNC sheet metal punching machine, JH21-400T pneumatic punch press machine for sale. The design principle of the punch press is to convert circular motion into linear motion. The main motor generates power to drive the flywheel. The clutch drives the gear, crankshaft, connecting rod, etc., to achieve the linear motion of the slider. The movement from the main motor to the connecting rod is Circular motion.

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

●Vertical located crank shaft , compact structure the crank shaft undergoes grinding treatment after highfrequency quenching , which has a good smooth finish and rotates flexibly ; lengthened rectangle hexguideway 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 noiseeliminate the clearance between connecting rod and sliding block , reduce the impactand wear of the stressparts.

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

●The key parts such as sliding block , guideways , worktable plate , connecting rod , and are all castings made ofresin 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 , thekey parts like pneumatic components . lectrical components , sealing parts , buttons and etc all adopt imported.
