Product Description

JH21 series open fixed table pneumatic punch  

JH21 series pneumatic punch produced by Woda Heavy Industry is mainly divided into open single point and open double point, with multiple models ranging from 25 tons to 400 tons.  Mainly suitable for blanking, punching, forming, bending, shallow drawing and other cold stamping process realization, widely used in electrical vehicles, agricultural machinery, tractors, mining machinery, hardware tools, machinery manufacturing and other industrial fields.  The use of pneumatic punch processing production is more sanitary, clean!  The use of advanced photoelectric protection technology, can achieve a significant improvement in safety performance, computer counting and program cooperation, can achieve unattended processing process, greatly improve the work efficiency, reduce the cost of production.  Welcome to inquire!  

 The working principle of pneumatic punch:  

1, pneumatic punch is pneumatic clutch will flywheel inertia force to the crankshaft, connecting rod, slider work;  Crankshaft connecting rod is rigid, so the slide block movement is mandatory, the same speed, the slide block stroke times and motion curve are fixed.  

2, compressed air can be stored in the air storage tank, ready to use, so the motor does not waste idle energy.  Using cylinder as working parts, using solenoid valve as control components, the machine structure is more simple, low failure rate, high safety, simple maintenance, lower maintenance cost, high production efficiency.  Use 220V power supply to realize the control of solenoid valve, simple and convenient operation.
