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
