ABSTRACT:
During press operation, the die gap is adjusted by adjustment members extending between the crown and the bed of the press, which adjustment members act in direction to move the two parts apart.
The adjustment members have a hydraulic fluid piston-cylinder means therein, and the distance between the dies is adjusted by expanding or contracting the adjustment members in the axial direction by supplying hydraulic fluid pressure thereto, thereby improving the operation of the press, and making it quite easy to deal with die gap variation during operation of the press and to restore the press to normal operation after a so-called "sticking" condition occurs.
