Patent number: 9895734Abstract: A device for manufacturing at least one undercut in a sheet-metal profile that is slotted or closed may include an inner core portion and an outer core portion, which together can be inserted within the sheet-metal profile and/or may support a semi-finished sheet-metal product from which the sheet-metal profile is formed. The inner core portion and the outer core portion may have faces that mate with one another such that when the inner core portion rotates or translates relative to the outer core portion, the outer core portion is forced away from the inner core portion. To cause this behavior, the faces may be undulating, inclined, or cam-like, for example. In effect, a cross-sectional profile of the device may be reduced at least for purposes of extracting the device from the sheet-metal profile after the undercuts have been formed.Type: GrantFiled: May 2, 2014Date of Patent: February 20, 2018Assignee: THYSSENKRUPP STEEL EUROPE AGInventors: Thomas Groβerüschkamp, Thomas Flöth, Michael Brüggenbrock

Publication number: 20160186280Abstract: Methods for producing subassemblies comprised of at least two metal components, at least one of which is comprised of a heat-treatable steel, may involve a number of steps. For example, a thermal joining technique may be employed to join the two metal components at one or more connection points to form the subassembly. One or more regions of the subassembly may then be hardened to cause one or more of the connection points to have at least partially a hardened microstructure.Type: ApplicationFiled: July 30, 2014Publication date: June 30, 2016Applicant: THYSSENKRUPP STEEL EUROPE AGInventors: Andreas BREIDENBACH, Jörg GORSCHLÜTER, Michael BRÜGGENBROCK, Ralf STEGMEYER, René HAMPE
