Patent number: 10954575Abstract: 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.Type: GrantFiled: July 28, 2016Date of Patent: March 23, 2021Assignee: BENTELER AUTOMOBILTECHNIK GMBHInventors: Stefan Konrad, Max Sander, Dieter Wulfes, Dimitri Schneider, Simon Werneke, Stefan Horn

Publication number: 20170066030Abstract: 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.Type: ApplicationFiled: February 6, 2015Publication date: March 9, 2017Applicant: BENTELER AUTOMOBILTECHNIK GMBHInventors: Georg Frost, Max Niesse, Jan Lackmann, Stefan Konrad, Hans-Gerd Lambers
