Abstract (en)

[origin: WO2013013803A1] The invention relates to a press-hardening tool (100) for producing hardened shaped sheet metal parts from a sheet steel material (400), comprising at least two tool parts which are movable in relation to each other in a working direction (D) and between which, under application of a pressure force (F) acting in the working direction (D), a heated sheet steel material (400) can be shaped and cooled and in the process hardened. It is provided that at least one of the tool parts (220) is formed in a segmented manner and has at least a first segment (221) having a shaped section extending transversely to the working direction (D) and at least a second segment (223) having a shaped section extending steeply with respect to the working direction (D), wherein the first segment (221) is arranged in a movable manner on the relevant tool part (220) and, when a particular pressure force (F) is exceeded, can yield (A) counter to the pressure force (F) applied, in order as a result to allow continued moving together of the tool parts and associated intensified pressing (B, C) of the second segment (223) against the sheet steel material (400).
