摘要： PROBLEM TO BE SOLVED: To provide a coil for electromagnetically expanding a tube, which has no part where the bend radius of a conductor is small, which is less prone to cause breakage due to the concentration of electromagnetic repulsive force despite repeated use and which is lightweight and compact for space saving.
SOLUTION: The conductor 2 enters the inside of an axis 1 through the hole 3 of the axis 1, in a bend radius a little smaller than that when being wound around the circumferential face of the axis 1. The conductor 2 does not bend in the longitudinal direction of the axis 1. In the inside of the axis, the conductor 2 is extended toward the base end of the axis 1 while being curved smoothly and is guided toward the base end of the coil through the center (centerline 5) of the axis 1. In this case the bent portion 101 of the conductor inside the axis touches the inner face of the axis. If R1 is defined as the radius of the circumferential face of the axis 1 around which the conductor is wound and R2 is defined as the inner radius of the axis, the following relationship is satisfied: 0.5≤(R2/R1)≤0.95.

摘要： PROBLEM TO BE SOLVED: To provide an electromagnetic forming coil of excellent durability and an electromagnetic forming method which enable magnetic field to be concentrated without using any magnetic flux concentrator. SOLUTION: A conductive wire 1 having a structure in which a surface of a core wire 6 of square section is covered with an insulating material 7 of a thickness of T is tightly wound in aligned condition around a shaft part 2 made of an insulating material so that the interval of the core wire 6 is 2T. A flange part 3 made of an insulating material is formed on a proximal end part of the shaft part 2. The sectional area of the core wire 6 wound around an end part of the shaft part 2 is smaller than the sectional area of the core wire 6 wound around other parts. In other words, a portion 6a wound around the end part of a shaft part 12 of the core wire 6 is thinner than the other portion 6b. Electromagnetic forming is performed by arranging the portion 6a of the small sectional area and a portion to be formed of a work 4 so as to be close to each other. COPYRIGHT: (C)2005,JPO&NCIPI
