    摘要: The invention relates to a method for producing a half-shell part with a drawing punch and a drawing die. The object of providing a method for the process-reliable and cost-effective production of highly dimensionally stable half-shell parts is achieved in that, in a single work step, the drawing punch is advanced into the drawing die, a sheet metal blank is preformed into a sheet metal raw part with at least one base section, at least one frame section and optionally a flange section, wherein during the preforming with the drawing punch a material excess is introduced either into the base section and the frame section or into the optional flange section of the sheet metal raw part, and the sheet metal raw part is finished to form a half-shell part and calibrated.
