Specifications

hydraulic punching press machine
1.four-column double drive
2. used for metal drawing, curling, flanging, cold-extruding

hydraulic punching press machine

1). This machine is applied in pressing malleability material. Such as blanking, curving edges, drawing press for sheet metal. It can be used to straighten, assembling, grinder wheel forming, cold-extruded metal parts forming, plastic and power forming.

 

2) Independent drive system and electric system; Center control buttons; Auto, manual and semi-automatic operation methods. The work pressure, press speed and stroke range can be adjusted by different technical requirement. And it can finish constant pressure and ting-ching forming. Constant pressure forming can suppress post-packing and delay auto-return action.
