摘要
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.
