| titleOfInvention | Manufacturing method of press-molded products |
| abstract | Provided is a method of manufacturing a press-formed product that can manufacture a press-formed product having a complicated shape even when an iron-based material that is excellent in high-temperature strength but difficult to form is used. First, an iron-based metal plate 20 (for example, a stainless steel plate) having a planar shape before press processing of a press-formed product is prepared. Next, the whole metal plate 20 is heated to a high temperature of 700 to 950 ° C. Subsequently, in the heated metal plate 20, the cooling block 30 is brought into contact with a local portion 23 of the metal plate that will form a crotch portion after press working, and the contact portion of the cooling block 30 and the periphery thereof are 100 to 600 ° C. Partially cool to low temperature. Finally, the metal plate 20 after partial cooling is pressed to give the three-dimensional shape of the crotch. [Selection] Figure 2 |
