Abstract

PURPOSE:To reduce the resistance received by a pipe expanding member and to reduce the tensile force by providing a bearing bracket through a thrust bearing on the backside of the pipe expanding member and by shifting the pipe expanding member while rotating in a pipe have internal spiral groove. CONSTITUTION:When the pipe expanding of a heat transfer pipe is performed, after a pipe expanding device is passed through a lubricating oil tank to dip a wire 1 and the pipe expanding member 2 to the lubricating oil, the wire 1 of the pipe expanding device is inserted through the heat transfer pipe 10. Then, when the top end of the wire is pulled by a proper device, the pipe expanding member 2 is advanced into the pipe 10, and following this, the pipe 10 is expanded. On the rear face of the pipe expanding member 2, as the bearing 4 is provided through a sliding bearing 3, when the pipe expanding member 2 is advanced and an axial force is loaded on the pipe expanding member 2, the rotation of the pipe expanding member 2 is not prevented. Therefore, the resisting force for the advance of the pipe expanding member is reduced and distortion of the pipe 10 is not generated.
