ABSTRACT:
A punch press has first and second sets of tooling mounted longitudinally of a press conveyor belt. The second set of tooling is located externally of the usual press columns. A second ram slidably mounted on the outside of the columns is driven by a connecting arm eccentrically mounted on a crankshaft extension. The second ram drives the upper tooling of the second tooling set in a reciprocating manner. The second ram can be operated out of phase with the main ram to reduce the total tonnage required of the press.
