ABSTRACT:
In a radial press having a press axis (A) , a plurality of outer cam surfaces (1, 2, 3, 4) at an angle to one another are grouped in two press yokes (18, 19) which are driven radially against one another. The planes of symmetry of the cam surfaces (1-2 and 3-4) disposed in the same press yoke are parallel with the drive direction. A number of outer cam follower bodies (31) lying between each pair of the outer cam surfaces serve for the radial advancement of press jaws (30) toward the press axis. Inner cam follower bodies (37) with additional press jaws (41) are driven synchronously by the outer cam follower bodies (31). To reduce weight and size the one press yoke (18) is guided with respect to the other press yoke (19) by traction posts (25, 26) which pass through the guiding press yoke (19) at its extremities lying outside of the cam surfaces (1, 2, 3, 4 ), are fixedly joined to the other, guided, press yoke (18), and are joined on the other side of the guiding press yoke to a traction-producing drive (52) which is preferably in the form of a hydraulic jack (47/51, 48/50) associated with each traction post.
