Wire rod wrapping method and wire rod wrapping device around the body

摘要

PROBLEM TO BE SOLVED: To provide a method of winding a wire rod around the outer periphery of a body portion by sequentially bending the wire rod from the tip end to the proximal end side along the circumferential direction on the outer peripheral portion of the body portion to plastically deform the wire rod without damaging the outer peripheral portion of the body portion. Wrap the wire around the outer circumference of the body. SOLUTION: A fitting hole 11 is formed in which a portion around which a copper wire 20 of a pipe 30 is wound can be fitted, and along a circular outer circumference of a portion where the copper wire 20 of the pipe 30 is wound around the inner circumference of the fitting hole 11. A block body 10 having an annular groove 11a formed therein is provided, and the copper wire 20 of the pipe 30 fitted in the fitting hole 11 is linearly formed in the block body 10 in the tangential direction of the circular outer circumference of the portion around which the copper wire 20 is wound. An insertion hole 12 is formed in which a linear copper wire 20 extending and wound around the outer periphery of the pipe 30 can be inserted from the outside, and the copper wire 20 inserted into the insertion hole 12 is blocked by the block body 10. A pressing rod 40 for pressing from the outside is provided. [Selection diagram] Fig. 3
