摘要： 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.

摘要： A reduction gear includes a reduction mechanism and a component which constitutes the reduction gear and in which a cavity portion is provided. The reduction mechanism is not provided in the cavity portion. The component includes a reinforcement structure which is provided to partially fill an inside of the cavity portion and forms a void, which is filled with air or fluid, in the cavity portion. The cavity portion includes only one opening with respect to a space in which the reduction mechanism is accommodated or with respect to an external space, or the cavity portion is provided so as to form a closed space inside the component.

摘要： The controller controls the gas supply of the gas supply unit so as to maintain a pressure in a metal pipe material at a first pressure when a gas is supplied into the metal pipe material which is formed into a pipe portion in a main cavity portion in a state where an upper die and a lower die are joined to each other. It is possible to prevent pressure drop in the pipe portion caused by cooling of the pipe portion due to a contact between the dies, and the pipe portion. Thus, it is possible to suppress a decrease in a force for pressing the pipe portion against the dies. It is possible to suppress a decrease in adhesion between the pipe portion and the dies when the metal pipe is formed, and it is possible to suppress occurrence of variations in hardenability in the pipe portion.

摘要： There is provided a reinforcement member for a vehicle which includes a cylindrical body section having a continuously closed cross section intersecting with a longitudinal direction. The cylindrical body section has a first surface, a second surface, and a third surface. The third surface has a fourth surface extending away from the second surface, and a fifth surface connecting the fourth surface and the first surface to each other. In a sectional view when viewed in the longitudinal direction, in a case where a virtual line connecting a first intersection portion where the first surface and the third surface intersect with each other and a second intersection portion where the second surface and the third surface intersect with each other is set, a third intersection portion where the fourth surface and the fifth surface intersect with each other protrudes outward with respect to the virtual line.

摘要： 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.

摘要： 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.

摘要： A forming device includes: a first cavity portion in which a pipe portion is formed and a second cavity portion in which a flange portion is formed, the first cavity portion and the second cavity portion being formed between a first die and a second die; a flange adjusting member which is capable of being advanced into the second cavity portion and is capable of being retreated from the second cavity portion, and which adjusts a length of the flange portion; and a control unit. The control unit sequentially performs a first control of allowing the flange adjusting member to be advanced into the second cavity portion, a second control of allowing the gas supply unit to supply a gas so as to temporarily form the flange portion, and a third control of allowing the flange adjusting member to be retreated from the second cavity portion.

摘要： A forming device includes: an upper die and a lower die having forming surfaces corresponding to outer surfaces of a pipe with protrusions; a moving mechanism that moves the upper die and the lower die such that a forming space for forming the pipe with protrusions is defined between the forming surfaces of the upper die and the lower die; and a gas supply unit that supplies gas to a forming material which is the base of the pipe with protrusions to expand the forming material. A control unit controls the movement of the upper die and the lower die by the moving mechanism and the supply of gas to the forming material by the gas supply unit such that the forming material is formed into the pipe with protrusions in the forming space.
