Abstract: A two-blow heating and forming tool for the simultaneous production of two hot-formed and press-hardened motor vehicle components is provided. The tool includes a heating device and a forming device, with at least two contact heating tools and at least two hot-forming and press-hardening tools being arranged next to one another in parallel in a press such that, during a closing movement, two blanks are heated and two heated blanks are hot-formed and press-hardened to form two motor vehicle components. A method for producing hot-formed and press-hardened motor vehicle components using a two-blow heating and forming tool is also provided, the method including producing two mirror-inverted motor vehicle components simultaneously in one press cycle.
