摘要： The invention relates to a four-die press tool (1), comprising a lower die assembly (4) and an upper die assembly (6) displaceable relative thereto, comprising four rams (10, 11, 12, 13) spaced apart and supported on the lower die assembly (4) or the upper die assembly (6) and carrying forging dies (29), and a ring (20) on which are mounted the four rams (10, 11, 12, 13) concentrically around the central press axis (28) of the four-die press tool (1) in such a way that they can be displaced relative to the central press axis (28) whenever the upper die assembly (6) is moved relative to the lower die assembly (4), wherein protecting means (35) are mounted on the ring (20) to secure a workpiece in a centered position on a central predetermined position of the workpiece relative to the central press axis (28) independently of a workpiece manipulator.
