  • 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.

  • Publication number: 20170066030
    Abstract: A hot forming line for producing hot formed and press hardened sheet metal products made from metal plates includes a heating station and a forming station. The heating station has a bottom tool and an top tool between which a metal plate is received. The metal plate is heated in the heating station by indirect resistance heating. The heat is generated outside the metal plate and is transmitted by heat conduction into the metal plate itself. For this the bottom tool and/or the top tool has an electric resistance heating with at least one surface heating element. The surface heating element is a heating plate with a plate body made of an electrically conductive material, wherein the plate body is configured as heat conductor. For this the plate body is slotted and is for example provided with a slot, which extends over the thickness of the plate body.

  • Publication number: 20150352753
    Abstract: The invention relates to a motor vehicle component and a method for producing a motor vehicle component having a metallic basic element and at least one reinforcing element made of a fiber composite material. An endless fiber strand of dry fibers is deposited here on a former, in a meandering manner around the extensions such that the two-dimensional fiber semi-finished product is formed. The fiber semi-finished product is trimmed and is brought into contact with the metallic basic element, wherein the fiber semi-finished product which is saturated with resin is cured by subjection to pressure and heat and thus the at least one reinforcing element is produced and is connected nonreleasably to the basic element.
