| 摘要 |
The present invention relates to a method for producing a shaped sheet metal component (15) having wall thicknesses (W, W1) differing from each other, in particular a motor-vehicle component, made from a steel material or light metal material, characterized by the following steps: - providing a sheet metal material having a constant wall thickness (W), - pre-shaping the sheet metal material into a preform (6) by means of a hold-down press (2), wherein at least one bulge (4) is produced in an inner region such that the material is stretched and has a reduced wall thickness (W1), - flattening and/or extending the produced preform (6), - wherein the sheet metal material is cut in order to form a blank (7) before, during, or after the pre-shaping, - optionally cutting and/or punching the blank (7), and - shaping the blank (7) into the shaped sheet metal component (15). A thereby produced axle subframe (201) is likewise disclosed. |
