Abstract: The invention is for a method to produce components from a blank made of deep-drawable material using a free-flowing action medium. The method consists in clamping the blank in a forming device in which the action medium applies a pressure to the blank, preforming the blank be elevating the pressure exercised by the action medium in restricted areas of the blank and finish forming the preformed blank with a forming tool.

Abstract: A method for producing components from a blank (1) made of a reshapable material, particular steel, in which the blank (1) is supported by a fluid cushion (F) against a shaping tool (5) during the deformation, and a device particularly intended for performing this method are disclosed. In the course of the method, the blank (1) is reshaped into an intermediate shape using the tool (5). Subsequently, the blank (1) deformed into the intermediate shape is locally deformed using a counter mold piece (6) which is moved against the blank (1) against the action direction (R) of the tool (5). In this way, exactly shaped components may be produced cost effectively without the danger of reduction in quality.

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.
