Abstract: A method for producing a wheel disk of a vehicle wheel may involve producing the wheel disk produced from a steel blank by hot forming. The blank may be at least partially hardened, preferably press-hardened, during or after the hot forming. The blank may be hot formed using at least one punch and at least one die, and at least one opening may be introduced into the blank using hot trimming means. At least one opening may be introduced during the hot trimming using at least one trimming bolt and an application bolt, wherein the application bolt may have at least one region having a cross-sectional shape that is variable in a longitudinal direction of the application bolt. Using the application bolt, the at least one opening may be calibrated via the variable cross sectional shape.

Abstract: A chassis component for a motor vehicle is disclosed. The chassis component (1) is manufactured at least partially from a multi-layer steel sheet (10, 20, 30). The multi-layer steel sheet (10, 20, 30) includes at least three steel layers, including two outer steel layers (11, 12; 21, 22; 31, 32) and one inner steel layer (13, 23, 33). At least one outer steel layer (11, 12; 21, 22; 31, 32) of the multi-layer steel sheet (10, 20, 30) has a tensile strength of at least 1200 MPa. A method for producing a chassis component for a motor vehicle, in particular a wheel (1) or a part thereof, is also disclosed.

Abstract: The invention relates to a method for the forming of a workpiece, in particular a blank, composed of sheet steel, in which method the following steps are performed in succession: providing a workpiece composed of multiple steel layers which have been non-detachably connected to one another by roll-bonding and of which at least two steel layers have a different strength and/or elongation at fracture, heating the workpiece, and subjecting the workpiece to hot forming. To ensure a high strength and at the same time the easiest possible formability, the invention proposes that at least one section of the hot-formed workpiece is hardened, and that the workpiece is subsequently subjected to cold forming in the region in which the hardening has been performed. The invention also relates to a corresponding workpiece.
