Abstract:
1. A method for manufacturing hardened components out of sheet steel, comprising: a) forming formed parts out of a steel sheet; b) before, during, or after forming the formed part, carrying out an end trimming of the formed part; c) after end trimming the formed part, heating at least some regions of the formed part to a temperature that permits an austenitization of the steel material; and d) after heating at least some regions of the formed part, transferring the component to a form hardening die, and in the form hardening die the component undergoes a form hardening in which the component is cooled and therefore hardened by virtue of the fact that at least some regions of the component are contacted and pressed by the form hardening die, wherein the component is supported by the form hardening die in the vicinity of a positive radii and at least in some regions and in the vicinity of cut edges, is clamped in a secure manner without distortion; in the regions in which the component is not clamped, the component is spaced apart from at least one forming die half by a gap.
