Abstract
A hot press processing apparatusincludes: a heating step of heating a workpiece W; a pressing step of press-molding, by an upper dieand a lower die, the workpiece W heated in the heating step after loading the workpiece W between the upper dieand the lower die; and a cooling step of bringing the coolant into contact with a front surface of the workpiece W that is molded and placed in a pressed state by the pressing step, to thereby cool the workpiece W and place the workpiece W in a quenched state. In the hot press processing apparatus, the workpiece W molded and placed in the pressed state by the pressing step forms gaps cwith respect to both of the upper dieand the lower dieso as to allow deformation at time of the cooling step except for an accuracy-guaranteed section Wr in the workpiece W.
