| description | A hot press processing device (1) includes a heating step in which a workpiece (W) is heated, a press step in which the workpiece (W) heated in the heating step is press-molded, and a cooling step inwhich the workpiece (W) heated in the press step is press-molded. A hard region (Zh) is generated in a workpiece (W) by cooling a portion of the workpiece (W) press-molded in a press step and causingmartensite transformation to occur in the portion, and a soft region (Zs) is generated in the workpiece (W) by cooling the other portion of the workpiece (W) and causing ferrite and bainite transformation to occur in the other portion. When the hot press processing device (1) performs the cooling process, the rigidity and the hardness of a specified part (Zb) in the soft region (Zs) are improved,and then the specified part (Zb) is cooled.
热压加工装置(1)包括加热工序、冲压工序以及冷却工序，在加热工序中，对工件(W)进行加热，在冲压工序中，对通过加热工序加热后的工件(W)进行冲压成型，在冷却工序中，对通过冲压工序冲压成型的工件(W)的一部分进行冷却而使该部分发生马氏体转变，由此在工件(W)内生成硬区(Zh)，另一方面，对该工件(W)的其他部分进行冷却而使该其他部分发生铁素体及贝氏体转变，由此在所述 |
