Technical Field
Certain embodiments of the present invention relate to a forming system and a forming method adapted to form a metal pipe.
Description of Related Art
Forming systems that perform forming by expansion with the supply of a fluid into a metal pipe material have been known. For example, a forming system disclosed in the related art is provided with a pair of upper and lower dies, a holding unit that holds a metal pipe material between the upper die and the lower die, and a fluid supply unit that supplies a fluid into the metal pipe material held in the holding unit. In this forming device, the metal pipe material is expanded by supplying a fluid into the metal pipe material held between the upper die and the lower die, and thus can be formed into a shape corresponding to a shape of the die. Such a forming method is referred to as hydroforming.
