Abstract

A device for shaping a blank into a hollow profiled element can include at least one base plate, onto which the blank that is to be shaped can be placed, at least one die core for the hollow profiled element, and at least two die halves for shaping the blank into the hollow profiled element. A method can include producing a hollow profiled element with at least one molded-on stiffening and/or functional element made from a blank. Hollow profiled elements can be produced at low cost, but at the same time ensure high reliability of a process where different hollow profiled elements are joined together by a generic device, wherein at least one form punch is provided for introducing an element structure into the planar blank that can be shaped and/or fixed into a stiffening and/or functional element.
