Abstract
The invention relates to a method and to a device for heat treating a metal component. The method comprises at least the following steps: a) heating the component; b) setting a temperature difference between at least one first sub-region and at least one second sub-region of the component; c) at least partially forming and/or cooling the component in a press hardening tool; and d) mechanically post-processing the at least one first sub-region of the component.
Claims7
A method for heat treating a metal component, comprising at least the following steps:
- a) heating the entire component in a first furnace;
- a1) moving the component from the first furnace to a temperature control station,
- b) within the temperature control station, thermally treating the component by subjecting at least one first sub-region to cooling and/or by subjecting at least one second sub-region to heating with a heating element so that the temperature control station affects a temperature difference between the at least one first sub-region and the at least one second sub-region of the component, the temperature difference between the at least one first sub-region and the at least one second sub-region not having been present prior to step b);
- b1) moving the component from the temperature control station to a second furnace,
- b2) heating at least the at least one first sub-region of the component in the second furnace,
- c) at least partially forming and/or cooling the component in a press hardening tool;
- and
- d) mechanically post-processing the at least one first sub-region of the component.
