METHOD FOR PRODUCING LOAD-OPTIMISED SHEET-METAL COMPONENTS

摘要

The invention relates to a method for producing sheet-metal components from a material, in particular for a car body, comprising the following method steps: pre-forming a workpiece to form a pre-formed component, wherein excess material is introduced into the pre-formed component at least in regions; and calibrating the pre-formed component to form an at least partially finally formed component using the excess material, wherein the pre-formed component is compressed in particular at least in sections, characterised in that the material has a yield strength R_p0.2 to tensile strength R_m ratio of R_p0.2 / R_m ≥ 0.53.
