摘要:
The invention relates to a method for producing a hardened sheet steel component, wherein sheet steel sheet bars are cut from a coil made of a hardenable steel alloy or steel strip, formed into sheet steel component blanks in a cold forming process, and the blanks are heated in a continuous furnace to a temperature above the austenitization temperature required for the hardening and pressed and quench hardened in a form hardening tool. The blanks have point-shaped or linear beads, raised bumps, or flanges whose free ends or partial lengths are bent relative to the contact element so that the blanks rest on the contact element using only the point-shaped or linear beads, raised bumps, or free ends or partial lengths of the flanges. During form hardening, the beads, bumps or bends are pressed or deformed into the desired geometry of the finished component.
