Method for producing components using a flowable active medium and a forming tool.

Abstract

The present invention relates to a method for producing components from a blank (P1-P4) made of a deep-drawable material, particularly steel using a free-flowing action medium. In the course of this method, the blank (P1-P4) is clamped in a forming device (U1, U2) and an action medium is applied to it. The blank (P1-P4) is then preformed by elevating the pressure (P) exercised by the action medium in a region of the blank (P1-P4) which is restricted to a section (V1, V2) of the blank surface and which partially covers the surface section (B1, B2) of the blank (P1-P4) from which the final form of the component is generated. Subsequently, the preformed blank (P1-P4) is finish formed using a forming tool (F1, F2). In this way, components having complex shapes may be produced with optimum exploitation of the properties of the material used.
