The present invention relates to a method for producing a hot-formed and quench-hardened tubular motor vehicle component (7) by way of internal high-pressure forming, a metallic starting material being at least partially heated to a heating temperature, in particular to a temperature above Ac3, being subjected to internal high-pressure forming in the hot state, and subsequently being quenched, preferably quench-hardened, wherein the internal high-pressure forming is performed as high-speed forming in a time of between 1 and 30 seconds, and the still-hot, formed motor vehicle component (7) is transferred into at least one separate quenching tool (5, 10) and is in particular quench-hardened, the motor vehicle component (7) being braced in a fixed position in the quenching tool (5, 10) and the cycle time of the quenching tool (5,10) corresponding to the cycle time of the internal high-pressure forming.
A method for producing a hot-formed and quench-hardened tubular motor vehicle component by way of internal high-pressure forming, a metallic starting material being at least partially heated to a heating temperature, in particular to a temperature above Ac3, being subjected to internal high-pressure forming in the hot state, and subsequently being quenched, preferably quench-hardened, wherein the internal high-pressure forming is performed as high-speed forming during a time of between 1 and 30 seconds, and the still-hot, formed motor vehicle component is transferred into at least one separate quenching tool and is in particular quench-hardened, the motor vehicle component being braced in a fixed position in the quenching tool and the cycle time of the quenching tool corresponding to the cycle time of the internal high-pressure forming.
A method for producing a hollow elongate shaped component from a steel material, in particular a motor vehicle pillar, characterized by the following method steps:
A motor vehicle pillar formed from a closed hollow profile with a cross section which varies over its longitudinal extent, the motor vehicle pillar being hot-formed and hardened and having a coating, wherein the hollow profile is formed from two sheet-metal blanks which are connected by way of a longitudinal weld seam which runs so as to be oriented in the direction of longitudinal extent, with two flanges, which protrude in an outwardly oriented direction and which at least partially overlap, being formed in the region of that side of the hollow profile which is situated opposite the longitudinal weld seam.
