METHOD FOR MANUFACTURING PIPE WITH FIXED MEMBER

To provide a method for manufacturing a pipe with a fixed member which manufactures a pipe with a fixed member into a desired shape while shortening a manufacturing time of the pipe with the fixed member.SOLUTION: A plurality of pipe fixed members are arranged outside of a pipe member at a plurality of fixing positions in an axial direction for a plurality of pipe fixed members of a pipe member, and an electromagnetic coil is arranged inside of the pipe member at the plurality of fixing positions of the pipe member. In this state, the plurality of pipe fixed members are caulked to the pipe member by applying a pulse to the electromagnetic coil so that the pipe fixed member of a first coupling part where the pipe fixed members are coupled to the outside of an engagement part of first and second pipe elements of the pipe member is caulked to the pipe member prior to a pipe fixed member of a second coupling part where the pipe fixed members are coupled to a position different from the engagement part of at least one pipe element out of the first and second pipe elements.SELECTED DRAWING: Figure 2 【課題】被固定部材付パイプの製造方法において、被固定部材付パイプの製造時間の短縮を図りつつ、被固定部材付パイプを所望の形状に製造することである。【解決手段】パイプ部材の複数のパイプ被固定部材についての軸方向の複数の固定位置におけるパイプ部材の外側に複数のパイプ被固定部材を配置するとともに、パイプ部材の複数の固定位置におけるパイプ部材の内側に電磁コイルを配置する。この状態で、パイプ部材の第１及び第２パイプ素子の嵌合部の外側にパイプ被固定部材が結合された、第１結合部のパイプ被固定部材を、第１及び第２パイプ素子の少なくとも一方のパイプ素子の嵌合部とは異なる位置にパイプ被固定部材が結合された、第２結合部のパイプ被固定部材より先に、パイプ部材にかしめ固定するように、電磁コイルにパルス通電することによりパイプ部材に複数のパイプ被固定部材を電磁成形でかしめ固定する。【選択図】図２
