Abstract: A molding device supplies a fluid and performs expansion molding of a metal material using at least a part of members of an existing press device.

Abstract: Provided is a forming device including a die, a lower base portion, an upper base portion, a pillar portion, and an electrical heating unit, in which, at a time of electrical heating performed by the electrical heating unit, a magnetic flux density inside the pillar portion is higher than at least one of a magnetic flux density at a center of a lower surface of the lower base portion and a magnetic flux density at a center of an upper surface of the upper base portion.

Abstract: Provided is a display device for a forming device that forms a heated metal material using a metal member. The display device proposes and displays a variable parameter that is adjustable.

Abstract: A forming apparatus which forms a metal pipe by expanding a metal pipe material, includes: a forming die for forming the metal pipe; a first electrode and a second electrode which clamp the metal pipe material at both end sides and heat the metal pipe material by causing an electric current to flow through the metal pipe material; and a first fluid supply unit and a second fluid supply unit which supply a fluid into the metal pipe material heated by the first electrode and the second electrode to expand the metal pipe material, wherein at least one of the first electrode and the second electrode is provided with a movement restriction mechanism which restricts a movement of the metal pipe material in an axial direction of the metal pipe material.

Abstract: A leveling technique that produces a high degree of flatness of strips and gives strips a characteristic such that parts cut from the strips by etching do not warp. Also, a method of leveling strips including the steps of rectifying a trip by tensioning and bending the strip with a tension leveler. The load acting on the strip by the tensioning and bending being 70% or more of the yield or proof stress of the strip. The method also including rectifying the strip by tensioning the strip with a roller leveler. The tension acting on the strip by the roller leveler being 50 N/mm2 or less.
