ABSTRACT:
A simplified heavy-duty press having a bed and a support head mounted from the press bed for limited vertical movement under predetermined spring preload. The entire drive (less motor) and rams are carried from the press head and these components are movable away from the bed when the tools between the ram and bed encounter an obstruction beyond the preload. The preload limits maximum operative force that will be transmitted in the mechanisms where precise control of the components/dimensions may be difficult to maintain because of manufacturing limitations or because of thermal expansion.
