Abstract

PURPOSE:To uniformly coat a lubrication/rust preventive on each element wire in good yield by penetrating an element wire through the liquid absorbing material impregnating a lubrication/rust preventive with its sliding at the fore step of a die and feeding it to the liquid absorbing material by utilizing the centrifugal force of the hollow shaft for feeding a center conductor rotating the lubrication/rust preventive, in case of twisting plural element wires by a wire twisting machine. CONSTITUTION:The necessary number of bobbins 22 are mounted in the peripheral direction via a cradle 21 on the cage 20 rotated by a motor 23, an element wire (a) is delivered from each bobbin 22 with rotating the cage 20 with its convergence to the die 2 via a butt strap 3 and twisted on the center conductor 1 from a hollow shaft S. A tank 8 for the lubrication/rust preventive is fitted to the hollow shaft S and the lubrication/rust preventive inside the tank 8 is fed to a felt made liquid absorbing material 4 via a tube 9 with the centrifugal force caused by the rotation of the hollow shaft S. The lubrication/rust preventive is stuck on the surface of each element wire (a) uniformly and in high yield with each element wire (a) penetrating through this liquid absorbing material 4 by its sliding.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is based on I2! This invention relates to a method for supplying lubrication and rust preventive agent to strands in a wire process.

[Conventional technology and its problems]

! 2! For wire manufacturing, for example, by using a gauge-type wire twisting machine, as shown in FIG.
) bobbins 22 are mounted at equal intervals in the circumferential direction, and the cage 2
While rotating the wire 0, the strands a are drawn out from each bobbin 22, converged on the die 2 through the batten 3, and twisted onto the center conductor 1 from the hollow shaft S.

In this stranded wire manufacturing process, in order to prevent the stranded wire from rusting after production, a rust preventive agent is supplied to the stranded wire, and when the stranded wire is compression molded in a later process, a lubricant is applied to the stranded wire. supply. This conventional supply method is generally carried out by dropping the wires just before or after each strand a is converged and passes through the combustion die 2.

However, when it is supplied just before the die, it is dropped directly onto each thin wire a, which tends to supply excess lubricant and rust preventive agent, which is not only uneconomical but also causes stickiness to be seen in the stranded wire. . In addition, it is impossible to avoid uneven supply, and unevenness in the degree of application becomes noticeable, resulting in problems such as spots appearing on the product at a later date.

The latter, which is supplied after twisting, is supplied to the outer surface of the stranded wire but is difficult to be supplied to the inner element wAa, and if it is difficult to be supplied to the inside of the stranded wire, there is a risk of rusting later.

[Purpose of the invention]

In view of the above points, it is an object of the present invention to provide a method that can uniformly apply an appropriate amount of a lubricant and rust preventive agent to each strand of a stranded wire.

[Means for achieving the purpose of the invention]

In order to achieve the above object, in the present invention, a liquid-absorbing material is disposed at a stage before the strands are converged and fed out from a bobbin mounted on a twisting machine and reach a twisting die, and the liquid-absorbing material At the same time, a lubricant/rust preventive agent tank is attached to the hollow shaft of the wire twisting machine, and the lubricant/rust preventive agent is absorbed from the outside of this tank through a tube. It was designed to be supplied to liquid materials.

[Effect]

The lubricant and rust preventive agent supply method configured in this way uses the centrifugal force generated by the rotation of the hollow shaft to impregnate the lubricant and rust preventive agent inside the tank through the tube and into the absorbent material. Since each wire is in sliding contact, lubricant and anti-corrosion agent can be reliably and uniformly applied to each wire.

〔Example〕

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

In the fi&1) machine shown in FIG. 2, as shown in FIG. Each strand a
Penetrate through sliding contact. Further, an annular tank 8 is integrally attached to the hollow shaft S, and the outer side of the tank 8 is connected to the liquid-absorbing material 4 via a tube S. When the hollow shaft S rotates with the lubricant/rust preventive agent in the tank 8, the lubricant/rust preventive agent moves toward the outside of the tank due to the centrifugal force, passes through the tube 9, reaches the absorbent material 4, and is impregnated. be done.

Therefore, the strand a fed out from the bobbin 22 mounted on the cage 20 is converged while traveling in the direction of the twisting die 2, but during its path, it slides into contact with and penetrates the liquid-absorbing material 4. The lubricant and rust preventive agent is applied reliably and evenly.
After that, it is twisted with the twisting die 2, and the capstan 2
4 and winding 1) is wound up by 25.

In this case, no lubricant or anti-corrosion agent is supplied to the center conductor 1, but if necessary, a liquid-absorbing material such as felt is provided on the downstream side of the batten 3, as shown by the chain line in FIG. 5 may be provided on the side by means of a holding plate 6 via bolts 7, or only the liquid-absorbing material 5 on the downstream side may be provided without providing the liquid-absorbing material 4 on the upstream side.

Since the lubricant and rust preventive agent are supplied by the rotational force of the hollow shaft S in this manner, the wire twisting machine is effective for those in which the hollow shaft S rotates at a high speed, such as the Zint type.

〔effect〕

As explained above, according to the present invention, it is possible to uniformly apply and supply the lubricant and rust preventive agent to each strand without excess or deficiency, thereby saving on the lubricant and rust preventive agent and improving the quality of the stranded wire.

Furthermore, since the lubricant and rust preventive agent are supplied by the rotational force of the hollow shaft, there is no need for a separate supply means such as a pump, and the cost is low.
