Abstract (en)
[origin: US4774828A] A radial press having a plurality of dies concentrically arranged about an axis of the press is described. In particular, the dies are movable in a radial direction relative to the press axis by means of a cam member axially displaced relative to a pressure pad by an hydraulic drive mechanism. The drive mechanism having a piston, piston rod and bearings is attached to a pressure pad and to the cam member in a manner providing a large clearance space accommodating a variety of workpieces in the rear portion of the press. During the pressing operation, the piston rods are stressed in tension eliminating the need for an end plate and tension rods of prior art radial presses.
