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 evenly applying and supplying an appropriate amount of a lubricant / rust preventive agent to each strand of a stranded wire.

[Means for achieving the object of the invention]

In order to achieve the above object, in the present invention, an eye-piece of the twisting machine is provided with an annular liquid-absorbent material around the entire circumference thereof, and the strands fed from each bobbin of the twisting machine, The liquid absorbent material is slidably contacted with the liquid absorbent material and penetrates through the eye plate, and a lubricant / rust preventive agent is supplied to the liquid absorbent material from the outside of the twisting machine.

Felt can be used as the liquid-absorbent material, and a lubricant / rust inhibitor can be supplied to the liquid-absorbent material by an external pump.

[Action]

With the lubrication and rust preventive agent supply method configured in this way, the liquid absorbent material is impregnated with the lubricant and rust preventive agent, and each element wire makes sliding contact with it, so the lubricant and rust preventive agent is surely attached to each element wire. And evenly applied.

At this time, since the liquid absorbent material is provided around the entire circumference of the eye plate and rotates together with the eye plate, the lubricant / rust preventive agent supplied to the liquid absorbent material is spread over the entire area of the liquid absorbent material by the rotation. It spreads smoothly, that is, it smoothly reaches each wire penetration portion and is reliably applied to the 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. The liquid absorbing material 4 has a microtube pump 8
As a result, the lubricant / rust inhibitor is supplied through the tube 9 and 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.

〔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.
