Stamping PRESS Abstract of the Disclosure A stamping press in which a frame supports a ram for reciprocating movement thereof and one or more wobble plates mounted on a main shaft operate a pivoted yoke for reciprocating the ram, and a die section mounted thereon. The ram is normally operated through two com- plete reciprocating movements for each revolution of the main shaft, and a counter-weight operated by the yoke is preferably included in the press structure for balancing the movement of the ram. The wobble plates may have a means for adjusting the angularity to vary the length of the ram stroke, and the crown of the press is pre- ferably hydraulically separated with respect to the base to provide a safety overload feature and easy ac- cess to the work pieces or tooling. In a modification, cams operated by the yoke may be used to drive the ram from the yoke as it is operated by the wobble plate to provide one complete reciprocating movement for each revolution of the main shaft. 1.
