摘要： To provide a forming device and a forming method capable of easily forming a flange part and a pipe part having a desired shape. By the control of a controller, a gas is supplied into a metal pipe material (14) from a gas supply part so as to expand a part of the metal pipe material (14) in sub-cavity parts (SC1 and SC2), and then a driving mechanism is driven such that expanded parts (14a and 14b) of the metal pipe material (14) are pressed by an upper die (12) and a lower die (11) to form flange parts (100b and 100c). In addition, by the control of the controller, a gas is supplied into the metal pipe material (14) after the formation of the flange parts (100b and 100c) from the gas supply part so as to form a pipe part (100a) in a main cavity part (MC). In this manner, the controller controls the gas supply part and the driving mechanism, and thus flange parts (100b and 100c) and a pipe part (100a) having a desired shape can be easily formed.

摘要： To provide a forming system and a forming method capable of improving sealing properties when a fluid is supplied to a metal pipe material. In a forming system (100), a controller (20) controls a heater (6) so as to heat end parts (14a and 14b) of a metal pipe material (14) at least before the supply of a fluid by a fluid supply unit (10). Therefore, at least before the supply of the fluid by the fluid supply unit (10), the end parts (14a and 14b) of the metal pipe material (14) are likely to be deformed by being heated by the heater (6). In such a state, the end parts (14a and 14b) of the metal pipe material (14) can be easily expanded by a pressing force generated by pressing nozzles (7 and 8) against the end parts (14a and 14b) of the metal pipe material 14, respectively. Accordingly, the nozzles (7 and 8) can secure sufficient airtightness via expanded parts (14c and 14d) of the metal pipe material 14.
摘要翻译：提供一种能够改善向金属管材供给流体时的密封性的成形系统和成形方法。在成形系统（100）中，控制器（20）至少在通过流体供给装置供给流体之前控制加热器（6）以加热金属管材（14）的端部部分（14a和14b）单元（10）。因此，至少在由流体供应单元（10）供应流体之前，金属管材（14）的端部（14a和14b）容易通过由加热器（6）加热而变形。在这样的状态下，金属管材（14）的端部（14a，14b）能够通过将喷嘴（7,8）按压在金属的端部（14a，14b）上而产生的推压力管道材料14。因此，喷嘴（7,8）能够经由金属管材14的膨胀部（14c，14d）确保充分的气密性。
