Apparatus for seperating by breaking

摘要

The dividing device includes a half-mandrel (7) with radius of curvature (RHD) constantly smaller than or variable relative to the radius (RD) of the breakthrough (4). The relatively soft sector, e.g. bearing cover (2'), in the breakthrough has resting surfaces (8, 9) on a further one-piece half-mandrel (7') or on guided punches (10).
