Steel material composite, method for producing a component, and use

The invention relates to a device and method for producing at least partially closed profiles from metal sheet, having a first tool part, a second tool part, and at least one supporting core. The insertion movement of the supporting core between the bending jaws is limited by a stop and, in its insertion position limited by the stop, protrudes with respect to the bending jaws in the direction of the die, in that the supporting core is arranged on a carrier that is movable relative to the die, and in that the bending jaws are assigned at least one displacement element connected rigidly thereto, the displacement element coming into contact with the carrier when the bent metal sheet portion engages around the supporting core.
