Abstract

Official abstract text for this publication.

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.

First claim

Opening claim text (preview).

What is claimed is: 1. A forming method for forming a metal formed material having a main body part, a pipe part, and a flange part, the method comprising: preparing a heated metal material between a first die and a second die; moving at least one of the first die and the second die in a direction in which the dies are combined together to form a first cavity part and a second cavity part communicating with the first cavity part between the first die and the second die, and forming the main body part and the flange part in the first cavity part and the second cavity part, respectively; and crushing the flange part by a flange forming member that can be allowed to advance or retreat in the second cavity part and forms the flange part, wherein the flange part is crushed such that a thickness of the flange part is smaller than a thickness of the pipe part.
