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.

Abstract: Press systems for manufacturing hot formed structural components are provided. The systems comprise a fixed lower body, a mobile upper body and a mechanism configured to provide upwards and downwards press progression of the mobile upper body with respect to the fixed lower body. The system further includes a cooling tool configured to cool down a previously heated blank. The cooling tool includes upper and lower mating dies, the lower die connected to the lower body with one or more lower biasing elements and/or the upper die connected to the upper body with one or more upper biasing elements. The system further includes a press tool configured to draw the blank, wherein the press tool is arranged downstream from the cooling tool. Moreover, methods for hot forming structural components are also provided.
