Embodiment Construction

[0067] Combine below Figure 1 to Figure 3 Three different advantageous embodiments of the method for producing a shaped part 1 from a preferably strip-shaped sheet metal semi-finished product 2 are specified. to this end, Figure 1 to Figure 3 Schematically shows the thermomechanical process sequence for producing a shaped part 1 according to a particularly preferred roll-forming method according to the invention in a combined heating and forming process of a sheet metal semi-finished product 2 in a roll-forming device implement.

[0068] The three preferred exemplary embodiments shown here differ in particular from the different process sequences in which the semi-finished sheet metal 2 is heated at least in regions before, during or after the deformation. The graphs each show time-dependent temperature profiles that occur in predetermined (spatially defined) regions A, B, C, D of the sheet metal semifinished product 2 before, during or after the individual forming steps. ...

Abstract

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 thesemi-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 subsequentcooling 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 orswage bending. The rollers are preferably cooled.

Description

technical field [0001] The invention relates to a method for producing a shaped part from a sheet metal semi-finished product, said shaped part having an increased structural strength at least in sections. Furthermore, the invention relates to a profiled part having at least one spatially defined region of increased structural strength, and also to the use of such a profiled part. Background technique [0002] Molded parts with high structural strength are used, for example, in automotive engineering for the production of structural components such as side impact beams, bumpers or for stiffening the A-pillar, B-pillar or C-pillar of a motor vehicle. Since very high demands are placed on such molded parts with regard to strength, high-strength, higher-strength and highest-strength steels are frequently used in their manufacture. Various deformation methods can be used for shaping the shaped part. For example, it is referred to herein as a bending method, in particular a rol...
