  • Patent number: 10151009
    Abstract: A method for producing a structural and/or safety-related motor vehicle component having at least one hot-formed and press-hardened part constructed from high-strength steel includes the steps of partially heat-treating a region of the motor vehicle component by heating the region to a heat-up temperature in a temperature range between 500° C. and 900° C.; maintaining the heat-up temperature for a duration of a holding time; and cooling down from the heat-up temperature in one or more phases. A body component constructed as a structural and/or safety-related motor vehicle component from a steel sheet blank that has been hot-formed and press-hardened includes joining flanges and/or coupling locations and/or safety-related parts, wherein the joining flanges, coupling locations and/or safety-related parts are partially heat-treated in several steps with the disclosed method.

  • Patent number: 8733144
    Abstract: A blank cut from a strip of hardenable hot-formed steel is heated in a furnace to a temperature which is smaller than an Ac3 transformation point in an iron carbon diagram. A first region of the blank is then heated in a conductive heating station to a temperature above the Ac3 transformation point and subsequently hardened in a hot forming and hardening tool to produce a steel part with at least two microstructured regions of different ductility.

  • Publication number: 20120309247
    Abstract: In a method of making a hybrid part, a reinforcement element of fiber composite is placed upon a base member in a press tool. A strip-shaped cover having a resin absorbing absorbent layer is withdrawn from a supply unit and placed in the press tool between the reinforcement element and the press tool. As the base member and the reinforcement element are compressed with one another and joined any resin issuing out from the reinforcement element is absorbed by the absorbent layer of the cover and kept away from soiling the press tool or the base member. After the compression process, the cover is removed.

  • Publication number: 20120192611
    Abstract: 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.

  • Publication number: 20120060982
    Abstract: In a method, a blank of unhardened steel sheet is subjected in a press tool to a hot forming and press-hardening process to produce a structural part. After press-hardening, at least one linear zone of the structural part is heat treated in order to increase ductility and reduce strength in the linear zone in relation to adjacent regions of the structural part. After heat treatment, a bending or cutting operation is carried out on the structural part along the linear zone.
