Title:
MOLDING DEVICE AND MOLDING METHOD
Document Type and Number:
WIPO Patent Application WO/2016/093147
Kind Code:
A1
Abstract:
Provided are a molding device and molding method whereby a pipe part and a flange part can easily be molded into a desired shape. Through control by a control unit, a gas is fed into a metal pipe material (14) from a gas feeding part so as to cause a portion of the metal pipe material (14) to expand into sub-cavity parts (SC1, SC2), after which a drive mechanism is driven so that portions (14a, 14b) of the expanded metal pipe material (14) are pressed by an upper die (12) and a lower die (11) and flange parts (100b, 100c) are molded. Through control by the control unit, the gas is fed from the gas feeding part into the metal pipe material (14) after the flange parts (100b, 100c) are molded, so as to cause a pipe part (100a) to be molded in a main cavity part (MC). The control unit thus controls the gas feeding part and the drive mechanism, whereby the pipe part (100a) and the flange parts (100b, 100c) can easily be molded into a desired shape.
