Steel door embossing press

1 Usage: an ideal machine for embossing steel door sheets. Has inching and semi-automatic functions.
2 Machine structure: three-beam, eight-column, single action. 
 

Three beams adopt high quality steel plates. Oil cylinder block is made of #35 forge piece. Oil cylinder's plunger piston is made of chilled cast iron, surface hardness: above HRC45.
 

Eight columns is made of #45 steel, quenched and tempered to HBS255-275, surface hardness after hard chrome plating: above HRC55. 
 

Guide sleeve: H59 copper bush, 8 pieces in total.
 

Hydraulic system adopts cartridge valve: simple structure, reliable without leakage, able to meet the need of high pressure and large flow, good heat dissipation, reduce reactive power loss to the lowest.
