Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of manufacturing a composite ring for use as a snow ring.

Conventionally, to manufacture composite rings, a steel pipe was cut into seven rings, and then a single piece of low-strength material was brazed together, but this method was time-consuming and expensive, and mass production was required. I was not prepared for this.

In view of the above points, the present invention aims to provide a manufacturing method that allows mass production of composite rings, and its characteristics are as follows:
A ferromagnetic metal alloy pipe with a large magnetic hysteresis loss is divided into two in the axial direction or a slit is made, and a ferromagnetic metal alloy with a low single point temperature of 00C or more is continuously joined to at least the cross section or the slit location to make a long pipe. The idea is to create a composite length and cut it perpendicular to its axis to create the desired ring.

The present invention will be explained based on the drawings.

Figure 1 (A) is a perspective view of the two-part copper vibrator 1, and Figure 2 (A) is a perspective view of the two-part copper vibrator 1.
A) is a perspective view of a steel pipe 2 with a slit 2a.

In the case of Fig. 1 (a), if the pipe is divided into two in the axial direction, one cross section like 1a is created, but as shown in Fig. 1 (b), a single piece of low-cutting material 6 is brazed to this, and a half-HJ Attach by attaching, welding, pressure welding, or organic adhesive 4. Thereafter, this is cut into desired shapes and combined with the other two-piece vibrator to form a composite ring.

In the case of Figures 2 (a) and (b), a low-cut single-point material filter is joined (brazing, soldering, welding, pressure welding) to one side or both sides of the slit 2a provided in the axial direction of the pipe.

(using an organic adhesive).

In this case, the desired ring is made by cutting it into a suitable size.

Both Figures 1 and 2 have been explained using steel pipes, but in addition to steel, there are other ferromagnetic metal alloys with large magnetic hysteresis losses, such as iron and permalloy.
Ii'e-Ni, Fe-Ni-Or, N
i-All.

Examples include Ni-8i alloy.

It is best to use low-strength one-piece materials with a thickness of 10 mm or less. The reason for this is that when /Qrnm is exceeded, the magnetic loss becomes small, and the ice and snow effect decreases.

When a single low-pressure ring manufactured by the method of the present invention was attached and a current of 20 OA was passed, the temperature near the composite ring relative to the wire temperature was +3°C at low temperature (atmosphere -7°C), -1100°C. , -100, +300,

An advantage of the method of manufacturing a composite ring of the present invention is that the ring can be made by cutting from a long object, so the cost is low.
