1. A forging apparatus comprising:
an upper die;
a lower die facing the upper die;
a heating mechanism configured to be able to heat the upper die and the lower die; and
a housing in which the upper die, the lower die, and the heating mechanism are arranged, the upper die and the lower die being configured to be movable relative to each other in a facing direction of the upper die and the lower die so as to be able to forge a forging material between the upper die and the lower die,
wherein the housing is integrally formed so as to surround the upper die, the lower die, and the heating mechanism, and comprises a housing body having a charging port opened so as to allow the forging material to pass therethrough, and a door configured to be able to open and close the charging port of the housing body, the housing body having an upper die passage port that is opened to allow the upper die to be inserted therethrough so as to be movable in the facing direction and a lower die passage port that is opened to allow the lower die to be inserted therethrough so as to be movable in the facing direction,
wherein an entirety of the housing is configured to be movable in the die facing direction,
wherein the heating mechanism is disposed so as to partially or entirely face outer peripheral side surfaces of the upper die and the lower die, and
wherein the heating mechanism is configured to move in the facing direction relatively with respect to the upper die and the lower die moving relatively.
