Patent number: 8261591Abstract: A semifinished hardenable-steel workpiece is introduced into a gap between a punch tool and a complementary die tool while the workpiece is heated above the AC3 point. Then one of the tools is vertically shifted toward the other tool so as to deform the workpiece to a predetermined shape. Subsequently the workpiece is gripped between the punch and the die tools while cooling at least one of the tools to press-quench the workpiece. Finally, but before the press-quenching is completed, an edge is cut off the still hot workpiece by relatively shifting an upper die and a lower die vertically past each other.Type: GrantFiled: July 24, 2009Date of Patent: September 11, 2012Assignee: Benteler Automobiltechnik GmbHInventor: Christian Hielscher

Publication number: 20120192611Abstract: In a method for producing a sheet metal part, a sheet metal blank is rolled to have at least two regions of different material thickness to define a thick region and a thin region, with a thickness profile of the sheet metal blank extending in substantial symmetric relationship to a central plane of the sheet metal blank. The sheet metal blank is inserted into a forming tool having a punch and a die and a punch-proximal side of the sheet metal blank is contacted with a pressing cam formed on the punch. The sheet metal blank is formed into the sheet metal part by pressing the punch against the die and thereby forming an embossment by a die cam provided on the die on a die-proximal side of the sheet metal part.Type: ApplicationFiled: January 30, 2012Publication date: August 2, 2012Applicant: Benteler Automobiltechnik GmbHInventors: Christian Hielscher, Otto Buschsieweke

Patent number: 8043681Abstract: In a method of making a hybrid structure, at least one support body is fixed in a tube component which is then placed in an injection molding tool. An injection-molded part is injection-molded to an outer surface of the tube component in an area of the support body. As a result, the tube component is inwardly deformed, when regions adjacent to the support body are exposed to an injection pressure, and forms indentations for engagement of the injection-molded part.Type: GrantFiled: December 15, 2008Date of Patent: October 25, 2011Assignee: Benteler Automobiltechnik GmbHInventors: Christian Handing, Christian Hielscher, Andreas Hitz, Andreas Wille
