HOT PRESS PROCESSING METHOD AND PROCESSING DEVICE

A hot press processing device 1 is provided with a heating step for heating a workpiece W; a press step for loading the workpiece W heated by the heating step between an upper die 11 and a lower die 12 and then performing press-forming by using the upper die 11 and the lower die 12; and a cooling step in which the surface of the workpiece W press-formed by the press step and in a pressed state isbrought into contact with a coolant to cool the workpiece W into a quenched state, wherein a clearance c2 is provided between the workpiece W formed by the press step and in a pressed state and both the upper die 11 and lower die 12 in order to allow portions of the workpiece W other than an accuracy-guaranteed portion Wr to be deformed in the cooling step. 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，将通过加热工序加热后的工件(W)运送到上模(11)与下模(12)之间后，利用该上模(11)和下模(12)进行冲压成型，在冷却工序中，使制冷剂与通过冲压工序成型且处于冲压状态的工件(W)的表面接触，由此对该工件(W)进行冷却而使该工件(W)变为淬火状态，通过冲压工序成型且处于冲压状态的工件(W)，在该工件(W)的精度保证部位(Wr)以外的部位与上模(11)和下模(12)这二者之间都形成间隙(c2)，以便在进行冷却工序时允许变
