|1. (WO2017020888) DEVICE AND METHOD FOR TEMPERING SECTIONS OF METAL COMPONENTS|
|Applicants:||BENTELER AUTOMOBILTECHNIK GMBH
|Title:||DEVICE AND METHOD FOR TEMPERING SECTIONS OF METAL COMPONENTS|
The invention relates to a device for tempering sections of hot-formed and/or press-hardened metal components (13), comprising a support structure (43) and a work head (8), said work head (8) having at least one contact element (11, 12) consisting of an electrically-conductive material, for heating sections of a metal component (13) using a flow of heat. Electrodes (15, 15a, 16, 16a) for resistively heating the contact element are connected thereto, and to a current source. According to the method, a hot-formed and/or press-hardened metal component (13) is first provided, and at least one contact element (11, 12) mounted on a work head (8) is heated to a temperature greater than a target temperature to which a section of the metal component (13) is to be heated. A contact surface of said contact element (11, 12) then comes into full-surface contact with the metal component (13) section to be heated, with a predetermined pressing force, such that the metal component (13) is heated to a target temperature in at least some sections by a flow of heat. The contact element (11, 12) is thus heated using resistive heating.
