摘要： A punch (27) and ram assembly (13, 36, 40) for a punch press (10) which clamps a workpiece prior to punching with the same mechanism used to strip the workpiece from the punch (27) as the punch is retracted. The elements of the clamping and stripping mechanism (36, 40) are carried and actuated by the ram (13) and its motion. The invention allows for adjusting the clamping and stripping force.
