摘要： A disclosed forming system is a forming system which expands and forms a metal pipe in a die. The forming system includes a preliminary forming apparatus which preliminarily forms a metal pipe material, a forming apparatus which includes a gas supply unit which supplies gas into the preliminary-formed and heated metal pipe material to expand the metal pipe material and a main body portion to which the die is attached, and a cutting device which cuts at least a portion of the formed metal pipe. The gas supply unit is provided so as not to be disposed on a first straight line which connects the preliminary forming apparatus and the main body portion in a plan view and a second straight line which connects the cutting device and the main body portion in a plan view.

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 gas supply part supplying a gas into a metal pipe material held and heated between a first die and a second die paired with each other. A driving mechanism moves at least one of the first die and the second die in a direction in which the dies are combined together. A first cavity part is formed between the first die and the second die to form the pipe part. A second cavity part communicates with the first cavity part to form the flange part. A flange forming member can be allowed to advance or retreat in the second cavity part, and forms the flange part. A controller controls the gas supply of the gas supply part, the driving of the driving mechanism, and the advance or retreat of the flange forming member.
