JH25 SERIES OPEN-BACK DOUBLE-POINY PRESS

JH25 SERIES OPEN-BACK DOUBLE-POINY PRESS

It is designed through adopting the high-rigidity frame structure. In addition, it is manufactured though welding the superior - quality steel plates and intimal stress is removed by means of annealing, so stability and reliability of precision of the complete machine are improved.

JH25 SERIES OPEN-BACK DOUBLE-POINY PRESS

It is designed through adopting the high-rigidity frame structure. In addition, it is manufactured though welding the superior - quality steel plates and intimal stress is removed by means of annealing, so stability and reliability of precision of the complete machine are improved.

The double crank shafts are designed in the reverse way, which counteracts side force of the linkage side block and improves stationary of transmission.

It adopts the symmetrical design method of the balancer device, which guarantees relative stationary of the machine's operation.

Combination of pneumatic wet-type friction plate clutch and brake and double solenoid valve with the famous brand are adopted, so machine have a long service life, lower noise.

The precision of die adjustment can reach 0.1mm and the die adjustment is safe, convenient and reliable; heat treatment quenching and precision grinding are conducted for the gear pair and sliding pair, so the transmission is stable, the precision is high and the durability is strong.  

The hydraulic overload protective device is adopted, so the machine can respond rapidly and sensitively and have high security. This machine adopts PLC control method, and it can be provide with the automatic production line uncoiling leveling device to achieve automated stamping of a single machine or many machines.
