Abstract
A tool for hot forming die quenching boron steel structural components having locally different microstructures and mechanical properties is described. The tool includes upper and lower mating dies, each die being formed by two or more die blocks including a working surface that in use faces the structural component to be formed, and side faces. The upper and lower dies include at least two neighboring die blocks adapted to operate at different temperatures corresponding to zones of the structural component to be formed having locally different microstructures and mechanical properties, wherein the neighboring die blocks are arranged with a gap between their side faces and end portions of the side faces of the neighboring die blocks that are close to the working surface are designed such that in use they are in contact.
