FORGING DEVICE, AND METHOD FOR MANUFACTURING FORGED PRODUCT

WIPO Patent Application WO/2020/217916

A1

The objective of the present invention is to provide a forging device and a method for manufacturing a forged product in which a decrease in the temperature of a forging space and the temperature of forging stock is prevented, uniformity of the temperature of upper and lower dies is maintained efficiently, and forging operational efficiency is improved. In this forging device and method for manufacturing a forged product, upper and lower dies are heated by means of a heating mechanism inside a housing in a state in which an introduction port of an integrally formed housing main body is closed by a door, the upper and lower dies are moved relative to one another in the facing direction thereof, and the heating mechanism is moved relative to at least one of the upper and lower dies, which are moving relative to one another, in the facing direction thereof, thereby subjecting the forging stock to forging between the upper and lower dies. In addition, in the method for manufacturing a forged product, the forged product is manufactured from the forging stock.
