  • Patent number: 10954575
    Abstract: A device and method for tempering sections of hot-formed and/or press-hardened metal components is disclosed having a support structure and a work head, the work head having at least one contact element consisting of an electrically-conductive material, for heating sections of a metal component using a flow of heat. Electrodes for resistively heating the contact element are connected thereto, and to a current source. A hot-formed and/or press-hardened metal component is first provided, and at least one contact element mounted on a work head is heated to a temperature greater than a target temperature to which a section of the metal component is to be heated. A contact surface of said contact element then comes into full-surface contact with the metal component section to be heated, with a predetermined pressing force, such that the metal component is heated to a target temperature in at least some sections by a flow of heat. The contact element is thus heated using resistive heating.

  • Patent number: 9694408
    Abstract: A hot forming line for producing hot formed and press hardened steel sheet products, includes: a forming device; a heating device having a temperature treatment station, wherein the temperature treatment station includes an upper tool and a lower tool, and at least one temperature treatment source; and exchangeable temperature treatment plates for conductive temperature treatment of a blank or part inserted into the temperature treatment station, wherein the exchangeable temperature treatment plates are constructed for arrangement on the upper tool and/or the lower tool, and the temperature treatment source is constructed for heating or cooling the temperature treatment plates. The temperature treatment station is constructed for treating different regions of the blank or part with different temperatures by conductive contact of the temperature treatment plates with the blank of part.
