Abstract (en)
[origin: CA2940676A1] The invention relates to a process and a device for producing a wheel nave (1) of a vehicle wheel, in which the wheel nave (1) is produced from a sheet (6) of steel by hot forming, the sheet (6) is at least partially hardened, preferably press-hardened, during or after the hot forming, wherein the sheet (6) is hot-formed by using at least one punch (7) and at least one die plate (8), and at least one opening (3, 4, 5) is introduced into the sheet (6) using hot trimming means (9, 10). The object of providing a process for producing a wheel nave (1) of a vehicle wheel with which a wheel nave (1) can be produced in a simple manner with high precision in such a way as to achieve a further weight reduction and meet the expected geometrical and safety requirements for the wheel nave (1) is achieved in a process and a device for producing a wheel nave (1) of a vehicle wheel by at least one opening (3, 4, 5) being introduced in the hot trimming by using at least one trimming pin (9) and a shutdown pin (10), wherein the shutdown pin (10) has at least one region (10a) with a cross-sectional shape that is variable in the longitudinal direction of the shutdown pin (10) and the at least one opening (3, 4, 5) is calibrated over the variable cross-sectional shape by using the shutdown pin (10).
