There is a A door frame pneumatic punching machine is a modern machine for punching and embossing sheet metal. It is an indispensable part of the production, as well as the press brake and shearing machine. Compared with traditional machinery, it has below benefits.

1 Steel plate welding bed, good precision, and strength

2 6 guide rails with good accuracy

3 Pneumatic clutch with double solenoid valve is safer

4 Hydraulic overload protection system can be used without vulnerable parts

5 The accuracy is good and the service life is long

6 The price is expensive, but the service life and safety are good

Principle of frame pneumatic punching machine

Pneumatic punch press uses a pneumatic clutch to transmit inertia force of flywheel to crankshaft, connecting rod, and slide block for working. High-pressure gas produced by the compressor is used to deliver compressed gas to the solenoid valve through the pipeline. The pedal switch is used to control the action of the solenoid valve to control the working and returning of a cylinder, so as to achieve the purpose of punching. The crankshaft and connecting rod are rigid, so the sliding block movement is mandatory. At the same speed, the stroke times and motion curves of the slider are fixed.

Main features

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

2 Vertical located crankshaft, compact structure; the crankshaft undergoes grinding treatment after high-frequency quenching, which has a smooth finish and rotates flexibly; lengthened rectangle hex guideway with a surface of bronze plate, which has high guide accuracy.

3 Pneumatic dual balance cylinder, balanced sliding block and punch weight, which reduces impact and noise, eliminate the clearance between connecting rod and sliding block, reduces the impact and wear of the stress parts.

4 The whole machine adopts PLC centralized control. The gas circuits adopt imported safety dual valves, which can achieve jog, inch, single and continuous punching.

5 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 levels, and improved the size accuracy 2-3 levels.

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.
