Publication number: 20130313763Abstract: Light metal components and/or plates are transported through a furnace in a clocked or continuous transport process and heated and optionally cooled inside the furnace by an air or gas flow. For this purpose, a continuous air-/gas circulation is generated, wherein circulating air-/gas flow flows across the light metal components and/or plates, heating and cooling them as necessary. The light metal components and/or plates entering into or exiting from the furnace perform a sealing function and prevent the air-/gas flow circulating in the furnace from escaping from the furnace.Type: ApplicationFiled: May 24, 2013Publication date: November 28, 2013Applicant: Benteler Automobiltechnik GmbHInventor: Jochem Grewe

Publication number: 20130127197Abstract: A motor vehicle sheet metal molding of the invention is produced by hot forming from a metal sheet composed of an aluminum alloy which cannot be precipitation hardened, which sheet is in the material state H12, H14, H16, H18, H19, H22, H24, H26, H28, H32, H34, H36 or H38 in accordance with the European standard EN515:1993 and contains at least magnesium and optionally manganese in addition to aluminum as alloy component. The motor vehicle sheet metal molding after forming has, at least locally, degrees of deformation which are above the forming limit curve of the aluminum alloy at room temperature. To produce the motor vehicle sheet metal molding, the metal sheet is heated at least locally to a temperature in the range from 200° C. to 400° C. over a period of from 1 to 60 seconds. The heated metal sheet is subsequently placed in a forming tool of a forming press and formed to produce the motor vehicle sheet metal molding.Type: ApplicationFiled: July 29, 2011Publication date: May 23, 2013Applicant: Benteler Automobiltechnik GmbHInventors: Holger Diersmann, Jochen Dörr, Jochem Grewe, Andreas Hitz

Publication number: 20100319428Abstract: A method for hydroforming hollow metal workpieces includes submerging the same in a reservoir of hydraulic fluid. A press is provided having a hydroforming station located within the reservoir and includes a forming cavity configured to receive the fluid filled workpiece and create a fluid cushion spaced between the outside of the workpiece and the inside of the forming cavity. Sealing mandrels supply high-pressure hydraulic fluid to the interior of the workpiece which hydroform the same to the shape of the final part. The outward flow of fluid from the fluid cushion space is controlled, along with the associated pressure, to maintain the fluid cushion at least until such time as the mandrel pushing step concludes, thereby alleviating friction and adhesion between the formed part and the forming cavity.Type: ApplicationFiled: June 21, 2010Publication date: December 23, 2010Inventors: Rafael Garcia Gomez, Jochem Grewe
