Claims17
A forming device that forms a metal pipe with a flange, comprising:
- a forming tool for forming the metal pipe,
- wherein the forming tool includes a first die and a second die that face each other in a first direction in a cross-sectional view, and a third die for regulating a planned flange portion of a metal pipe material, and
- the third die continues to correct misalignment of the planned flange portion until the first die and the second die are clamped.
A metal pipe comprising:
- a hollow pipe portion;
- and
- a pair of flange portions protruding from the pipe portion to both sides in a width direction,
- wherein sizes of the pair of flange portions in the width direction are predetermined sizes different from each other.
A forming device that forms a metal pipe with a flange, comprising:
- a forming tool for forming the metal pipe,
- wherein the forming tool includes a first die and a second die facing each other in a first direction in a cross-sectional view, and a third die disposed on at least one side of a metal pipe material in a second direction intersecting the first direction, and
- the third die moves away from the metal pipe material as the first die and the second die approach each other.
