Japanese Patent JP6875341
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a molding system and a molding method capable of improving a sealing property when supplying fluid to a metal pipe material.SOLUTION: In a molding system 100, a control part 20 controls a heating part 6 so as to heat edge parts 14a and 14b of a metal pipe material 14 at least on a stage prior to supply of fluid by at least a fluid supply part 10. Therefore, at least on the stage prior to the supply of fluid by at least the fluid supply part 10, the edge parts 14a and 14b of the metal pipe material 14 are heated by the heating part 6 and, thereby, are turned to an easily deformable state. Because the edge parts are turned to such a state, the edge parts 14a and 14b of the metal pipe material 14 can be easily expanded by pressing force generated by pressing nozzles 7 and 8 against the edge parts 14a and 14b of the metal pipe material 14. Accordingly, the nozzles 7 and 8 can secure satisfactory air-tightness via expansion parts 14c and 14d of the metal pipe material 14.SELECTED DRAWING: Figure 2
