Radialpresse zum Verpressen von rotationssymmetrischen Hohlkörpern

摘要

Radial press (1) comprises a press frame with press yokes (2, 3) that move relative to each other, and a press drive with a press jaw assembly (14) forming a press tool. The press jaw assembly has at least four press surfaces (8a-11a) which are arranged together with their support bodies (8-11) so that they can be moved relative to a workpiece axis. Each press yoke has a recess (4, 5) with first sliding surfaces (6a, 7a) on which at least two support bodies lying opposite each other are displaceably arranged relative to a separating gap (T). The first sliding surfaces are parallel to each other and perpendicular to the press direction (P) and form a control square. Two of the support bodies interact with a wedge-shaped pressure body (12) moving parallel to the separating gap. The pressure body is mounted in the recesses between two second sliding surfaces (6b, 7b). The second sliding surfaces enclose an angle ( alpha ) selected so that the path of the pressure body paralle l to the separating gap is the same length as that of the press path of the press yokes perpendicular to the separating gap.
