Abstract (en)
[origin: WO0176787A1] The invention relates to a method for producing components from a blank (P1 - P4) consisting of a deep-drawable material, especially steel, using a flowable active medium. During this method, the blank (P1 - P4) is clamped in a forming device (U1,U2) and exposed to the active medium. The blank (P1 - P4) is then preformed by increasing the pressure (P) exerted by the active medium in an area of the blank (P1 - P4) which is limited to a partial 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 produced. The preformed blank (P1 - P4) is then finished using a forming tool (F1,F2).
