Title:
熱間成形された構造部材のための道具
Document Type and Number:
Japanese Patent JP6649384
Kind Code:
B2
Abstract:
A tool for manufacturing hot formed structural components having locally different microstructures and mechanical properties, the tool comprising upper and lower mating dies, each die being formed by two or more die blocks comprising one or more working surfaces that in use face the structural component to be formed and one or more supporting blocks, the upper and lower dies comprising die blocks are adapted to operate at different temperatures corresponding to zones of the structural component to be formed having locally different microstructures and mechanical properties, the die blocks including one or more warm die blocks adapted to operate at a higher temperature, and one or more cold die blocks adapted to operate at a lower temperature, and wherein at least one of the warm die blocks is an electrically conductive die block which is electrically connected to a current source configured to provide a DC current through the die block to control the temperature of the die block. Furthermore, a method for manufacturing hot formed structural components is also provided.
