Abstract (en)

[origin: WO0176786A1] The invention relates to a method for producing structural elements from a blank (1) consisting of a deformable material, especially steel, according to which the blank (1) is supported during the deformation process by a fluid pad (F) against a shaping tool (5). The invention further relates to a device for carrying out the inventive method. According to the inventive method, the blank (1) is shaped to an intermediate shape by means of the tool (5). The blank (1) shaped to an intermediate shape is then deformed in a locally limited manner by means of a counter mold (6) which is moved against the blank (1) counter to the effective direction (R) of the tool (5). The invention provides a method for producing exactly shaped structural elements at low costs and without any loss in quality.
