ABSTRACT:
A device for adjusting the shut height of a press includes a rotatable dial (16) interposed between a ram mounting block (6) fixed to a press ram (2), and a tooling ram (14). The dial (16) is keyed to a screw bushing (12) which is rotatable in a screw threaded bore in the block (6) for vertical movement relative to the block (6). Facing surfaces (46 and 48) of the block (6) and the dial (16) are formed with opposed helical ramps (54 and 56, and 58 and 60). The angular position of the dial (16) is adjustable to cause the ramps (54 and 56, and 58 and 60) to cooperate to alter the distance between ramps (2) and 14) to adjust the shut height of the press.
