Method for fabricating press forming die and method for fabricating press forming punch
A press forming die is fabricated by initially fabricating a die forming panel, by press forming, which provides a die surface for the press forming die. During fabricating the die forming panel, a shaped panel is obtained by initially press forming a first blank material with a die forming prototype and a punch forming prototype. Next, the shaped panel is mounted onto the punch forming prototype again and, thereafter, a die forming panel is obtained by press forming a second blank material. The die forming panel is then mounted on a frame body and a backup material is formed between a space between the frame body and the die forming panel, thereby fabricating the press forming die. Since the die surface of the press forming die can be shaped by press forming, the press forming die can be simply fabricated.
