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

摘要

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