摘要： A method for hot-forming and hardening a sheet-metal component with flanges in a cooled forming tool and an apparatus for carrying out the method are disclosed. A heated sheet-metal blank is inserted in a forming tool having a hollow form, with the sheet-metal blank projecting over the hollow form in marginal regions. The sheet-metal component formed from the sheet-metal blank is hardening of in the hollow form. A first flange having an X-bending axis is formed in a first marginal region with an auxiliary tool, and a second flange having a Y-bending axis is formed in a second marginal region with the auxiliary tool. The auxiliary tool has a plurality of dies, and the X- and Y-bending axes are not collinear and may be orthogonal to each other. Bending axes with a substantially perpendicular mutual orientation can be produced simultaneously in a single forming step.

摘要： In a method of making a hardened sheet metal part, a blank is cut to form a region defined by at least one cutting edge having a cutting depth which is smaller than a material thickness of the blank. The blank is subjected to a hot forming step and at least in one area is allowed to harden. After the hot forming step, the region is pushed along the cutting edge.

摘要： A method and apparatus for making sheet metal components includes heating a sheet of hardenable steel to its austenitizing temperature and hot forming the same in a hot forming tool to define a formed workpiece. The formed workpiece is held in the hot forming tool for a first holding time. The formed workpiece is then removed from the hot forming tool and immediately placed in a cooled, form holding tool and is held therein in a closed condition for a second holding time. The form holding tool may be constructed from a material that has greater heat conductivity than that of the hot forming tool.

摘要： A hardenable steel workpiece having two regions is first hardened so that both regions are of generally the same low ductility. Then only one of the regions is hot coated so as to increase the ductility of the one region while not heating and changing the ductility of the other region. The workpiece can be hardened by hot working or tempering. The hot coating can be done by dipping the one region in molten zinc.
