PROCESS FOR PRODUCING A LOCALLY HARDENED PROFILE COMPONENT, LOCALLY HARDENED PROFILE COMPONENT AND USE OF A LOCALLY HARDENED PROFILE COMPONENT

摘要

The present invention relates to a process for producing a profile component (i) which at least in sections has a structurally increased strength from a semifinished sheet metal part (2), in which the semi-finished sheet metal part (2) is formed in an at least one-stage bending process and the bending process and also subsequent parting and cutting operations on the semifinished sheet metal part (2) are combined with a thermal treatment of at least one geometrically delineated region (A, C, D) of the semifinished sheet metal part (2), which comprises at least one heating step and a subsequent cooling step, in such a way that the at least one geometrically delineated region (A, C, D) has a structurally increased strength after cooling. Bending can be effected by means of roller profiling or swage bending. The rollers are preferably cooled.
