In a radial press with a press spindle (A), a plurality of external control surfaces (1, 2, 3, 4) at an angle to one another are arranged in groups in two press yokes (18, 19) which are driven radially in relation to one another. The planes of symmetry of the control surfaces (1, 2 or 3, 4) which are arranged in the same press yoke extend parallel to the direction of drive. A plurality of external control bodies (31), which are situated between two of the external control surfaces in each case, are used for the radial advancing of pressing jaws (30) towards the press spindle. Internal control bodies (37) with further pressing jaws (41) are driven synchronously by the external control bodies (31). To reduce weight and size, one press yoke (18) is guided in relation to the other press yoke (19) by tie rods (25, 26), which penetrate the leading press yoke (19) on its ends situated outside the control surfaces (1, 2, 3, 4), are fixedly connected to the other guided press yoke (18) in each case and are connected on the opposite side of the leading press yoke to a pulling drive (52) which is preferably designed as a dedicated hydraulic drive (47/51, 48/50) which is assigned to each tie rod (25, 26). <IMAGE> |
