ABSTRACT:
The drive cylinder component of a hydraulic press is reciprocable relative to a fixed ram to drive the press slide toward the press bed for the performance of work on a workpiece between the slide and bed. The cylinder component is provided with an integral radially outwardly extending flange about the periphery thereof at the open end of the cylinder, and the press frame is provided with a stop plate surrounding the cylinder and disposed in the path of the flange so as to be engaged thereby as the cylinder approaches its lowermost position with respect to the press bed. The stop plate and flange are adapted to take a full press tonnage load. The flange also supports guide components engaging gibbing on the press frame for guidance and support of the cylinder and thus the slide during reciprocation thereof.
