Abstract
The invention relates to a method for producing a press-hardened molded sheet metal part (100) having at least one press-in element (200), comprising the following steps: heating a sheet metal blank; punching at least one form-locking recess (120) in the region of the press-in element (200) to be fixed; hot-forming the sheet metal blank into a sheet metal molded part (100) and press-hardening the sheet metal molded part (100); forming a hole (110) in the sheet metal molded part (100) such that the punched form-fitting recess (120) lies next to the hole (110); and pressing a press-in element (200) into the bore (110), the press-in element (200) having a flange (220) with at least one anti-torsion feature (230) which is pressed into the punched form-fitting recess (120). The invention also relates to an alternative method and to a press-hardened sheet metal molded part produced according to the invention, comprising at least one press-in element (200).
