ABSTRACT:
A universal cam unit for use in a power press comprising a driver assembly, a slide block to which the working tool is mounted, and a mounting bracket for coupling the slide block to the ram for movement therewith. The slide block is slidably mounted to move between a retracted and an extended position. The slide block and the driver assembly include parallel inclined bearing surfaces which abut when the pressure pad and the ram are lowered. As the ram motion continues, the inclined bearing surfaces slide against each other thereby causing the slide block to move from the retracted to the extended position. The movement of the slide block brings the tool into engagement with a workpiece disposed between the pressure pad unit and the lower die to perform a desired operation. The components of the universal cam unit may be disassembled and selectively replaced, so that the unit may be quickly and easily adapted for use in a desired application.
