Abstract
A coil unit is inserted into a tube member, an electromagnetic-forming coil part is arranged at a tube member forming position, a coil-side terminal is connected to a power-supply-side terminal of an end part of a high-voltage power supply cable, the electromagnetic-forming coil part is energized by a power supply part to electromagnetically form the tube member, the coil-side terminal and the power-supply-side terminal are separated, and the coil unit is removed from the tube member. Thus, the tube member can be separated from the high-voltage power supply cable during transport.
Claims6
A tube-member-forming method comprising, in the following order:
- inserting a bar-shaped coil unit having an electromagnetic-forming coil portion into a tube member from a distal part of the coil unit;
- positioning the electromagnetic-forming coil portion at a forming position of the tube member;
- connecting a coil-side terminal and a power-side terminal to each other, the coil-side terminal being provided in a proximal part of the coil unit and being electrically continuous with the electromagnetic-forming coil portion, the power-side terminal being provided at an end of a power cable extending from a power source;
- electromagnetically forming the tube member by supplying a current from the power source to the electromagnetic-forming coil portion;
- separating the coil-side terminal and the power-side terminal from each other;
- and
- removing the coil unit from the tube member.
