Abstract

The invention relates to a method for producing a component, said method comprising: preforming a workpiece to a preformed component having a base region, a side-plate region, and optionally a flange region, such that the preformed component has a material surplus for the side-plate region and/or the base region and/or optionally the flange region; and calibrating the preformed component to an at least in regions finally formed component having a base region, a side-plate region, and optionally a flange region; wherein the base region of the preformed component has substantially the geometry and/or the local cross sections of the base region of the at least in regions finally formed component. The invention moreover relates to a device for producing a component, in particular for carrying out the method.
