Abstract (en)

[origin: WO2011083008A1] The invention relates to a method for producing a half-shell part having a drawing mandrel (1) and a drawing die (2). The aim of creating a method for the process-secure and cost-effective production of highly dimensionally stable half-shell parts is achieved by the invention in that, in a single work step, the drawing mandrel is advanced into the drawing die, a sheet metal blank is preformed to a sheet metal raw part having at least one base section (4), at least one frame section (15) and optionally one flange section (23'), wherein during preforming with the drawing mandrel a material excess is introduced either in the base section and the frame section or in the optional flange section of the sheet metal raw part and the sheet metal raw part is finished so as to form a half-shell part (3) and calibrated.
