Description

[Detailed description of the invention] The present invention relates to a stranded wire manufacturing device, in which multiple strands of wire necessary for a stranded structure are drawn simultaneously while being drawn at the same time, and then the stranded wires are continuously drawn. The purpose of this is to improve quality and economic efficiency by processing.

As shown in FIG. 1, a conventional stranded wire manufacturing apparatus involves two processes: a wire drawing machine and a stranding machine.

To explain this based on the drawings, Figure 1A shows the mechanism of a general wet wire drawing machine, in which a raw wire 2 is drawn out from a supply wire reel 1, and a die 4 placed between each take-up cone 3 is drawn out. After passing through one by one and turning to Chiyapustan 5, the traverser
The film is wound up onto a winding reel 7 via a winding reel 6.

Several reels wound with strands of required thickness drawn by this wire drawing machine are supplied to the wire twisting machine shown in FIG.

That is, the winding reel 7 after wire drawing is set in the cradle 8 of the cylindrical wire twisting machine for the number of water changes, and each strand 9 (the figure shows the case of three stranded wires) is placed around the outer periphery of the twisting machine rotor 10. After passing through the mirror plate 11, the fibers are gathered at the voice 12 and twisted together.

The twisted strands 13 are taken off by a take-up capstan 14, passed through a traverser 15, and wound up into a winding loop 16 to form a finished stranded wire.

However, in the above-mentioned conventional manufacturing equipment, the wire drawing machine draws only one strand through several dies at a high speed of several hundred meters per minute, resulting in unreasonable plastic working. Become,
As a result, wire breakage occurs during wire drawing, causing the machine to stop, resulting in short, defective products, which negatively affects operating rates and yields.

Furthermore, winding 1) - The winding tension of the wire can cause the reel's Francia winding body to become distorted or damaged, or winding failures may occur due to a faulty trapper, which can lead to tangles and breakage when used in a wire twisting machine. bring up

On the other hand, in terms of quality, the wire is drawn at high speeds, which accelerates the wear of the dies, which can damage the wire surface or cause the wire to not be drawn into a perfect circle, resulting in defects in size.

In addition, the winding reel is stored due to the supply and demand relationship with the wire twisting machine, which causes the problem of rusting during storage.

Because of this problem, a humidity control device must be installed in the factory.

Next, since the wire twisting machine is a cylindrical wire twisting machine, the reel diameter of the supplied strands is limited, which means that the reel has to be changed more frequently, and the wire threading work involved. The operating rate will be greatly reduced, and at the same time, the number of machines per person will be restricted, and personnel costs will increase.

Table 1 below shows the conventional operating rates.

As is clear from the above table, the overall operating rate is 50%, which shows that the efficiency is very low.

The present invention solves the above-mentioned problems associated with conventional manufacturing, and aims to shorten the process and achieve economical and quality effects.

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

Embodiment As shown in FIG. 2, the raw wires 2 are drawn out from the supply wire reel 1 for the number of twisted fibers (three twists are shown in the drawing), and the dice 17- are placed between the respective take-up cones 3. A single die with a plurality of holes is formed into a plurality of dies or a set of dies is made into a set, and this is sequentially passed through a plurality of sets (three-hole dies are shown in the drawing). The original wires 2 are simultaneously drawn while being taken up by the same double-coat stan 18, and then drawn at a constant speed by the capstan 18, and each strand is converged by the twisting roller 19. After winding the wire several times, the wire is wound around an overtwist roller 20 several times to give an overtwist to the wire.

The above-mentioned overtwisted strands are guided from the axis of the flyer 24 via the guide roller 25 to the flyer guide roller 21, and further guided from the flyer guide roller 21 arranged on the flyer 24 on the opposite side to the guide roller 2.
5, the fibers are guided from the axis of the fryer 24 to a cradle 26 which is swingably suspended between the fryers 24 and 24, and are twisted twice by the rotation of the fryers 24 and 24.

The twice-twisted wire is taken off at a constant tension take-off station 22 arranged in a cradle 26, and transferred to the traverser 1.
5 and is rolled up on a winding rail 16.

In addition, the constant tension take-off Chiyapustan 22 is the torque motor 2.
1 is driven by 3.

As mentioned above, the present invention uses a multi-hole die or a plurality of dies to wind a plurality of strands of wire around the same wire, and draws the wire at the same time. The present invention provides an apparatus for producing twisted wires using a machine.

Therefore, by adjusting the wire drawing speed to the twisting speed, wire drawing can be performed at a low speed, which reduces wear on the dies, eliminates wire breakage during wire drawing, and improves the fatigue limit due to uniform wire drawing in terms of quality. Conventional problems such as drawing wire to a perfect circle size can be largely resolved.

In terms of operation, it is possible to sufficiently increase the operating rate since it is possible to omit replacing the intermediate take-up reel and stopping the machine due to various troubles.

Next, in the case of twisted wire, even if various reels were collected and adjusted to a uniform tension as in the past, there was still a problem of poor twisting. This is simultaneous wire drawing, in which the actual wire is wound and drawn at the same time, and since the wire is drawn uniformly and the wire is twisted under uniform tension,
It is possible to completely eliminate twisting and wire adjustments, etc.
The synergistic effects of improving the operating rate and yield of wire drawing and stranding will be very large.

That is, according to the present invention, the overall operating rate is approximately 90% as shown in Table 2.

As mentioned above, the present invention involves simultaneously drawing multiple wires to the required thickness in the same wire drawing section, feeding the wires directly into the wire twisting section, and twisting the wires in a high-speed double twist type puncher twisting machine. As a result, the overall operating rate is improved by about 80% compared to the conventional method, and it is possible to reduce the number of dies, improve quality, and reduce product loss.
