Description

DETAILED DESCRIPTION OF THE INVENTION <Field of Industrial Application> The present invention relates to a power supply body used for rotating bodies such as wire drawing machines, plating equipment, and commutators.

<Prior Art> Conventionally, materials such as phosphor bronze, aluminum alloy, and cast iron have been used as power feeders for feeding power to rotating bodies.

<Problems to be solved by the invention> However, many of the conventional power feeders of this type have poor power feeding characteristics due to poor wear resistance and Φh1 such as high-speed rotation power feeders. and!,:.

<Means for resolving the problems> In view of the above-mentioned deficiencies of conventional power supply bodies, we have investigated the possibility of obtaining a power supply body that is lightweight, has excellent wear resistance, and has no change in power supply characteristics even during high-speed rotation. This is what led to this invention.

That is, the present invention uses a three-dimensional network structure, which can be integrally processed with AQ or A0 alloy, as a main component of Ni- or Ni-gold alloy, to be composited by casting with Al or A&alloy. The structure is lightweight and has wear resistance by using the above structure and a cast body made of 80 or A4 alloy in which 80 forms an intermetallic compound containing Ni as a main component.

<Operation> The present invention will be explained below based on the drawings showing one embodiment thereof.

FIG. 1 is a smaller front view of the main part showing the rotary power supply A to the wire rod 1, and FIG. 2 is a sectional view thereof. The power is supplied to this power feeder by high-speed rotation to a wire in contact with the outer periphery, and a three-dimensional network structure 3 made of N or Nj gold alloy 1-component is arranged on the periphery of the JV2. What kind of cast body is it made of?

In addition, in FIGS. 3 and 4, a three-dimensional 4ft structure 3 similar to the above is arranged in the center of the peripheral edge 5 of the rotating body 4, and a J
The rotating body is made of a cast body in which V 2 is cast, and the three-dimensional I! The brush E3 of the power supply section 7 is in contact with the surface of the four-structured body 3 to supply power.

The layer of the three-dimensional structure 3 in the center is J in FIG.
It is preferable that the outside of the sea urchin be flush with the aluminum cast/v.

Next, Fig. 6 shows a rotary body 91\power supply body 10 that supplies power, a body is placed in a three-dimensional mesh M4i at the contact part 11 with the rotary body 9, and ui/v is cast with Al 2 on the outside. It is a body.

<Practical example> Examples will be described below based on the above-described drawings.

Example 1 A three-dimensional network structure mainly composed of Ni was arranged around the peripheral edge of a rotating power supply body as shown in Fig. 1, and an M alloy with an AC4G composition was cast, followed by solution treatment at about 510°C for 8 hours. Then, annealing treatment was performed at 160° C. for about 6 hours to obtain a rotating body.

Example 2 AN alloy of AC4G composition was cast into a disc-shaped three-dimensional network structure mainly composed of Ni, and treated under the same conditions as Example 1 to form a power supply body 4 as shown in FIG. 3. I got it.

Example 3 AC8AC10/V gold alloy was cast into a plate-like three-dimensional network structure mainly composed of Ni Cr alloy, AC8A T
6 treatments, i.e. solution treatment at 520°C for 4 hours and 170°
C for about 10 hours to obtain a power supply body 10 as shown in FIG.

The electrical conductivity and usage results of the power feeders obtained in Examples 1 to 3 above were compared with those of conventional phosphor bronze, /V gold alloy with AC40 composition, and cast iron manufactured as shown in the following table. The results were obtained.

Table 1 (Song Dynasty) As mentioned above, a three-dimensional network structure mainly composed of Nj or N1 alloy was cast with Ap or M alloy to form a composite.
The power feeder of the present invention is lightweight and wear-resistant. It was recognized that the power supply characteristics were good, and the power supply characteristics were also excellent.
