Patent ID: 8590353

Claim:
A process for producing shaped components from high-strength and ultra high-strength steels with tensile strengths >780 MPa, comprising: feeding a steel sheet-metal strip having longitudinal edges to a roll-forming installation and in the roll-forming installation passing the steel sheet-metal strip through roll stands and deforming the steel sheet-metal strip using deformation rollers acting on the steel sheet; in order to avoid hydrogen embrittlement in plastically deformed regions of the deformed steel sheet-metal strip, introducing compressive stresses to the steel sheet-metal strip by overbending and bending-back to a desired component geometry; for the over-bending, in particular of flange regions, of profiled sections, using straight or conical rollers, which are arranged between the deformation roll stands; wherein the over-bending rollers are used to carry out bending which is greater than would be required for the shaping, and a subsequent roll stand then bends the over-bending back to the desired component geometry; and removing an oversize in the plastically deformed regions of the longitudinal edges by chip-forming or grinding machine.
