The following description will be given taking the case of fastening the rubber hose H as an example, but the present invention is not limited to this. Note that the sleeve portion 1 and the nipple portion 3 cooperate to form a hollow cylindrical space 2 into which the hose H is inserted. The sleeve 1 and the nipple 3 are made of a conductive material such as aluminum or low carbon steel. When the coil for diameter expansion described later is not inserted into the nipple portion 3, it is not necessary that the nipple portion 3 be a conductive material.

ある。The coils 11 and 16 for diameter reduction and diameter expansion in each of the electromagnetic forming devices 13 and 18 need to have a strength to withstand a repulsive force generated during molding. For this reason, the outer diameter and the inner diameter of the coil for diameter reduction / expansion processing are usually buried in reinforced plastics (epoxy resin or the like) 14, 19, respectively, and the shape thereof is maintained. The first shock current generator 12 includes a high-voltage power supply 21, a charging switch 22, a capacitor 23, and a discharging switch 24, and can be represented by an equivalent circuit as shown in FIG.
The high-voltage power supply voltage in the first impact current generator 12 is usually 5 to 10 kV, and the capacitor capacitance is usually 50 to 150 kV.

Is turned off, the discharge switch 24 is turned on, and a large current is instantaneously passed through each machining coil. Then, the strength of the magnetic field also changes in response to a sudden change in the current flowing through each of the coils 11 and 16. An induced current flows through the sleeve portion 1 in a direction that hinders the change in the magnetic field, and the sleeve portion 1 receives a force according to Fleming's left-hand rule by the induced current and the magnetic flux density generated by the machining coil. The diameter is reduced as shown in FIG.

効果を奏する。<Function / Effect of the Invention> The method for fastening a hose joint according to the present invention is, as described above, a method for fastening a hose member to a hose joint having a nipple portion and a sleeve portion forming a hollow cylindrical space,
After the hose member is inserted into the hollow cylindrical space, the sleeve portion is reduced in diameter and the hose member is fastened to the hose member. In order to reduce the diameter by the electromagnetic force generated by instantaneously passing a large current through the coil, the diameter of the coil is reduced.
It works.
スリーブ部が非接触で縮径されるため、従来のかしめ
ダイスをスリーブ部の表面に直接接触させて縮径加工す
る場合の如く、スリーブ部表面のメツキがはがれたり、
スリーブ部表面が傷付いたりすることがない。Since the sleeve part is reduced in diameter in a non-contact manner, as in the case where the conventional caulking dies are brought into direct contact with the surface of the sleeve part to reduce the diameter, the surface of the sleeve part is peeled off,
The surface of the sleeve is not damaged.

来のダイスかしめの如く、ホース縮径率が周方向でのば
らつきが大きくなるおそれがない。The diameter reduction processing on the sleeve is completed at the moment when the ripple deformation does not occur in other parts, and the force acts uniformly over the entire circumference. For this reason, even if the hose is uneven in thickness, there is no fear that the variation in the diameter of the hose in the circumferential direction increases in the circumferential direction as in the conventional die crimping.
また、ニツプルの内側に拡径加工用コイルを配設した

ともにニツプルが変形するおそれをなくすことができ
る。Further, when the diameter-enlarging coil is provided inside the nipple, it is possible to eliminate the possibility that the nipple is deformed together with the sleeve when the diameter of the sleeve is large.
