    Abstract: A forming device includes a blow-forming die and a shielding member. The blow-forming die includes a first die that protrudes from a first die holder towards a second die holder and a second die that protrudes from the second die holder towards the first die holder. The shielding member is configured to extend from the first die holder to the second die holder before the blow-forming die commences forming a flange part of a pipe in a sub-cavity part. The sub-cavity part is between a main cavity part and the shielding member. The shielding member is separated from the first die and the second die.

    Abstract: A molding apparatus capable of improving the quality of a molded article is provided. A control section controls a blowing mechanism to expand and mold a metal pipe material by supplying gas into the metal pipe material held between an upper mold and a lower mold by a pipe holding mechanism. The control section controls a driving section to mold a flange portion by crushing a second molded portion of the expanded metal pipe material in a sub-cavity portion between the upper mold and the lower mold. In a molding apparatus, the control section changes movement speed of a slide during the molding of the flange portion by controlling a servomotor. Accordingly, it becomes possible to control an operation of pressing at an appropriate movement speed according to the shape or the like of the flange portion. Accordingly, it is possible to improve the quality of a molded article.

    Abstract: A forming system includes: a forming apparatus which supplies gas into a cylindrical metal pipe material having a welded portion to expand the metal pipe material; a supply device for supplying the metal pipe material to the forming apparatus; and a control device for controlling an operation of the supply device, in which in a case where a position where a distance from a center of the metal pipe material is the longest, on a surface of the die, when viewed from an extension direction of the metal pipe material in a state where the metal pipe material is disposed between the dies, is a longest position, the control device includes a control unit which controls supply of the metal pipe material to the forming apparatus such that the welded portion is not located on a straight line connecting the longest position and the center of the metal pipe material.

    Abstract: A molding apparatus that molds a metal pipe with a flange is disclosed. The molding apparatus includes a first mold and a second mold that are paired with each other, a slide that moves at least one of the first mold and the second mold, a drive unit that generates a driving force for moving the slid, a holding section that holds a metal pipe material between the first mold and the second mold, a gas supply section that supplies gas into the metal pipe material held by the holding section, and a control unit that controls the drive unit, the holding section, and the gas supply section. The first mold and the second mold are provided with a first cavity portion that molds a pipe portion of the metal pipe, and a second cavity portion that molds a flange portion.

    Abstract: By the control of a controller, a gas is supplied into a metal pipe material from a gas supply part so as to expand a part of the metal pipe material in sub-cavity parts, and then a driving mechanism is driven such that expanded parts of the metal pipe material are pressed by an upper die and a lower die to form flange parts. In addition, by the control of the controller, a gas is supplied into the metal pipe material after the formation of the flange parts from the gas supply part so as to form a pipe part in a main cavity part. In this manner, the controller controls the gas supply part and the driving mechanism, and thus flange parts and a pipe part having a desired shape can be easily formed.
