Abstract
The invention relates to a method for producing partially-hardened components from steel sheets, in which a component that is cold-formed from a hardenable steel sheet material is heated, in a furnace, to a temperature below the austenitization temperature (<AC3), and a radiating element acts upon the component in sections where said component is to be austenitized (<AC3), this radiating element having a component-side contour that corresponds to the contour of the component in the section to be austenitized. The invention also relates to a device for carrying out said method.
Claims9
A method for producing partially hardened components out of sheet steel, comprising:
- heating a component that is cold formed out of a hardenable sheet steel in a furnace to a temperature below an austenitization temperature (<Ac3);
- and
- acting on the component with a radiating element in regions in which the component should be austenitized (>Ac3);
- wherein the radiating element has a three-dimensional contour on a side oriented toward the component, which approximately corresponds to a contour of the component in the region to be austenitized.
