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 vehicle body structure includes a support member of a vehicle body, and a reinforcement member disposed along a longitudinal direction of the support member of the vehicle body to reinforce the support member of the vehicle body. The reinforcement member is a processed product formed by shaping a tubular body, and includes a flange portion that protrudes on an outer peripheral portion and that is formed in the longitudinal direction of the support member of the vehicle body. The flange portion is joined to the support member of the vehicle body at a location other than locations where the support member of the vehicle body is joined to other members different from the reinforcement member.

摘要： 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.
