Technical introduction of JH21 power press

1 Suitable for various cold stamping process :blanking, punching, molding, bending, pulling and stretching etc Widely used in the field of electrical appliances, vehicles, agricultural machinery, tractors,mining machinery, hardware and tools, machinery manufacturing, and other industrial field

2 Welded body with steel plate, higher stiffness and accuracy, Adopts longitudinally placed crankshaft, compact structure and beautiful appearance.

3 Adjust die height adjustment electrically by CNC controller. Slider square figure long guide with six frictions and bronze liner, which is higher precision.

4 Adopts combined friction clutch and brake, engages stably and runs sensitively, Fixed with the slide, the mechanical overload protector will protect the machine from overloading.

5 Lift balance cylinder, makes the slider rod balance.
