Optional Accessories for 4 Column Double-Action Press
Movable workbench, buffer device for blanking, photo-electric safety device, oil cooling device, displacement sensor, industrial touch screen, hydraulic or mechanical material smashing device, die clamping mechanism, die protection device, imported PLC

Main Features of 4-Column Double-Action Press
1. The double-action press follows a computer optimization design, which simplifies the structure and improves price-performance ratio.
2. On the basis of the welded-steel plate construction, the 4 column press does well in high accuracy and eccentric loading resistance.
3. Fitted with a cartridge valve, the hydraulic control system is proud of good reliability, long working life and small hydraulic shock. It has reduced connecting pipelines and leakage points.
4. Controlled by an imported PLC, its electrical system comes with compact structure, high sensitivity, reliable operation and easy maintenance. There are hydraulic cushions in the floor beam. Through an operation panel, the operator can choose operating cycle modes, namely blank pressing with ejection, blank pressing without ejection, and blank pressing with hydraulic cushion.
5. Operating mode of hydraulic press: Adjusting, manual, semi-automatic
6. Forming process specification: Stroke setting and pressure setting
