Description

TECHNICAL FIELD The present invention relates to a method for supplying a lubricant / rust preventive agent to a wire in a twisting process.

[Conventional technology and its problems]

Stranded wire production, for example, by a gauge type stranding machine, has a cage 20 rotated by a motor 23, as shown in FIG.
The required number (six in the figure) of bobbins 22 are mounted at equal intervals in the circumferential direction via the cradle 21, and while rotating the cage 20, the wires a are drawn out from the respective bobbins 22 and each wire a is marked. It converges on the die 2 through the plate 3 and is twisted on the central conductor 1 from the hollow shaft S.

In this twisted wire manufacturing process, in order to prevent rusting of the twisted wire after manufacturing, a rust preventive agent is supplied to the twisted wire, or a lubricant is applied to the twisted wire when the twisted wire is compression molded in a subsequent step. To supply. This conventional feeding method is generally carried out by dropping just before or after each strand a is passed through the twisting die 2 (see Japanese Utility Model Publication No. 41-4029).

However, what is supplied immediately before the die is dripping directly on each thin wire a, so it is easy to supply an extra lubricant and rust preventive, which is uneconomical and the twisted wire is sticky. . Further, it is impossible to avoid uneven supply, and unevenness in the degree of coating is conspicuous, and there is a problem that spots are found on the product at a later date.

The latter, which is supplied after twisting, is supplied to the outer surface of the twisted wire but is difficult to be supplied to the internal strand a. If it is difficult to supply it inside the stranded wire, it may cause rusting at a later date.

[Object of the Invention]

The present invention has been made in view of the above points, and an object thereof is to provide a method capable of uniformly applying an appropriate amount of a lubricating rust preventive agent to each strand of a stranded wire.

[Means for achieving the object of the invention]

In order to achieve the above-mentioned object, in the present invention, a liquid absorbing material is provided on the eye plate of the twisting machine, and the wires fed from each bobbin of the twisting machine are slid on the liquid absorbing material. While contacting and penetrating, also penetrating the eye plate, a lubricant / rust preventive agent tank is attached to the hollow shaft of the twisting machine, and the liquid absorption through the tube from the radially outer part of the hollow shaft of the tank. It is configured to supply a lubrication and rust preventive agent to the conductive material.

Felt can be used as the liquid absorbent material.

[Action]

The lubrication / rust preventive agent supply method configured in this way is such that the centrifugal force generated by the rotation of the hollow shaft causes the lubricant / rust preventive agent in the tank to be impregnated by the outside through the tube to reach the liquid absorbent material. Since each wire is in sliding contact with each other, the lubricant and rust preventive agent is surely and uniformly applied to each wire.

〔Example〕

 Embodiments of the present invention will be described below with reference to the accompanying drawings.

In the twisting machine shown in FIG. 2, as shown in FIG.
An annular liquid-absorbent material 4 made of felt is provided on the rear surface of the eye plate 3 at the tip of the hollow shaft S, and each wire a is slidably penetrated through the liquid-absorbent material 4. Further, an annular tank 8 is integrally attached to the hollow shaft S, and an outer portion of the tank 8 is connected to the liquid absorbent material 4 via a tube 9. When the hollow shaft S rotates with the lubricant / rust preventive contained in the tank 8, the centrifugal force causes the lubricant / rust preventer to move closer to the outer side of the tank to cause the tube 9 to move.
The liquid-absorbent material 4 is passed through and is impregnated.

Therefore, the wire a fed from the bobbin 22 mounted on the cage 20 is converged while advancing in the direction of the twisting die 2, but in the path, the wire a slidably penetrates the liquid absorbent material 4. The lubricant / rust preventive agent is surely and uniformly applied, and then twisted by the twisting die 2, taken up by the capstan 24 and taken up by the winder 25.

In this case, the lubricant / rust preventive agent is not supplied to the central conductor 1, but if necessary, as shown by the chain line in FIG. 1, a liquid absorbing material such as felt is provided downstream of the eye plate 3. 5 may be provided side by side with the holding plate 6 via the bolt 7. Further, only the liquid absorbent material 5 on the downstream side may be provided without providing the liquid absorbent material 4 on the upstream side.

In this way, since the lubrication / corrosion preventive agent is supplied by the rotating force of the hollow shaft S, the twisting machine is effective for a rotating shaft of the hollow shaft S, for example, a rigid type.

〔effect〕

As described above, according to the present invention, the lubricant / rust preventive agent can be uniformly applied and supplied to each strand without excess or deficiency, and the lubrication / rust preventive agent can be saved and the quality of the twisted wire can be improved.

Further, since the lubrication / rust preventive agent is supplied by the rotating force of the hollow shaft, a separate supplying means such as a pump is not required and the cost is low.
