Abstract
A mechanical press having a very precise shutheight control system. 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.
Claims6
A mechanical press comprising:
- a frame;
- a bed connected to said frame;
- a slide connected with said frame for reciprocating motion opposing said bed, said slide and said bed defining a shutheight of said press when said slide is at bottom dead center;
- a drive mechanism attached to said frame for driving said reciprocating slide, said drive mechanism including a drive piston and a tie rod;
- and
- a shutheight control system having a chamber located between said piston and said tie rod, said shutheight control system further including a pressurizing means in communication with said chamber for selectively pressurizing said chamber with a predetermined pressure, said pressurizing means causing said tie rod to one of expand and contract to thereby control shutheight.
