ABSTRACT:
A mechanical press having a very precise shutheight control system is disclosed. The press includes a bed connected to a frame with a slide connected with the frame for reciprocating motion opposing the bed. The slide and bed together define a shutheight of the press. A drive mechanism is attached to the frame for driving the reciprocating slide, the drive mechanism includes a drive piston and a tie rod. The shutheight control system includes a chamber located between the drive piston and tie rod with a pressurizing mechanism in communication with the chamber for selectively pressurizing the chamber with a predetermined pressure. The pressurizing mechanism causes the tie rod to one of expand and contract to thereby control press shutheight.
