Abstract (en)
Provided is a forming device that forms a heated metal material. The forming device includes a die that performs quench forming by coming into contact with the metal material; and a cooling unit that cools the die. The cooling unit suppresses deterioration in hardenability to the metal material resulting from accumulation of heat to the die caused by repeated forming.
