Abstract: Methods for using a mold to partially harden semifinished products, which are comprised of hardenable steel and have at least partially an open-profile or closed-profile cross section, may involve a number of steps. For example, such methods may involve heating regions of a semifinished product above an AC1 temperature, positioning the semifinished producing in a mold, positioning an active mold cooling element adjacent to or in contact with the heated regions of the semifinished product, and cooling the regions of the semifinished product at a defined cooling rate so that a hardened microstructure in the cooled regions. These methods and corresponding devices provide low cost solutions that dispense with complete hardening of semifinished products and/or employing welded connections to provide various mechanical properties.

Abstract: A method for producing a wheel disk of a vehicle wheel may involve producing the wheel disk produced from a steel blank by hot forming. The blank may be at least partially hardened, preferably press-hardened, during or after the hot forming. The blank may be hot formed using at least one punch and at least one die, and at least one opening may be introduced into the blank using hot trimming means. At least one opening may be introduced during the hot trimming using at least one trimming bolt and an application bolt, wherein the application bolt may have at least one region having a cross-sectional shape that is variable in a longitudinal direction of the application bolt. Using the application bolt, the at least one opening may be calibrated via the variable cross sectional shape.

Abstract: A tailored semifinished part (5, 6, 7, 8, 9) is disclosed in the form of a metal sheet or strip which is formed from a first blank (1) and at least one second blank (2) and the first and at least one second blank are physically, frictionally and/or adhesively (3) joined to one another. The first blank (1) may be an ultrahigh-strength, monolithic material. A motor vehicle component (5′, 6′, 7′, 8′, 9′) may be made of the tailored semifinished part (5, 6, 7, 8, 9).

Abstract: Disclosed herein is a wheel, in particular for vehicles, such as motor vehicles, with a rim ring having an opening defined there through, and with a main support at least partially arranged in the opening in the rim ring. The wheel, despite having a low weight, provides adequate rigidity and strength and can be produced in a simple manner, while maintaining design flexibility. The main support of the wheel has a plurality of spokes, and a plurality of covering parts for at least partially covering the spokes, wherein the main support and the covering parts support the rim ring.
