  • Method for the production of a cold formed piece part made out of a steel plate
    Patent number: 6883218
    Abstract: This invention relates to a procedure for manufacturing cold-formed components (R) out of sheet steel and use of a sheet bar comprising the following steps: Generation of a sheet bar (P) out of a base plate (G), which consists of a first steel material; replacement of at least one section of the base plate (G) with a sheet steel blank (1, 2) whose thickness (D1, D2) or at least one material property differs from the first sheet steel (G), wherein the thickness (D1, D2) and/or deviating material property and the geometry of the sheet steel blank (1, 2) and its position in the sheet bar (P) are determined by the material flow during the ensuing cold forming process; and cold forming of the sheet bar (P) to fabricate the component (R). The procedure according to the invention ensures an improved result of cold forming, or even enables the manufacture of specific component shapes in the first place.
