ABSTRACT:
An internal high-pressure deformation method for the production of in particular bulging out closed hollow bodies and a corresponding device are disclosed. At least two workpiece parts (1,2) are employed, wherein at least one of the two workpiece parts (1,2) preformed of cup shape and exhibits a flange, and are pressure agent sealingly pressed in the region of the flanges (1.1,1.2) in the deformation tool according to the invention such that the two work tool pieces (1,2) are together deformed by the internal high-pressure deformation method and are further processed separately or jointly after the internal high-pressure deformation. The apparatus is subdivided in tool regions (E1, E2, E3, E4) corresponding to the work piece forms to be generated and corresponding to the number of the workpiece parts (1,2), wherein the tool regions (E1,E2,E3,E4) are disposed in different planes (FIG.2).
