In this regard, a cooling device 8 is fitted airtightly so as to extend over the twisting port plate 19 and a die holder 21, and the atmosphere is adjusted and cooled to prevent a generation of scale of the strand 20.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an m-wire, particularly a method for manufacturing a multi-core stranded wire, and an improvement in the apparatus thereof.

In the conventional maw manufacturing method, in the case of the post-annealing method, the drawing and stranding wires are separated, which requires a large amount of installation space for manufacturing equipment, and wastes power in transferring semi-finished products between each process. It had the disadvantage of contributing to Therefore, the present applicant has proposed a patent application for the purpose of integrating the wire drawing, annealing, and wire twisting processes, thereby converting the entire device into a shed, reducing the installation area, reducing power consumption, and improving productivity. 55-55478
．． 55-737111 etc. was proposed.

However, in both of these, the structure is such that the internal pressure of the annular path is high and high temperature is confined, which is a container composed of walls that fit together while moving the materials, so the generation of frictional heat becomes large.
As a result of the material becoming hotter than other parts and reducing the deformation resistance of the material, there was a drawback that a large amount of heat was inevitably generated. In addition, the ability of a wire twisting machine is determined by the twisting speed, that is, the number of rotations, so in order to perform surface twisting at even higher speeds, it is necessary to
Keep rotating parts as small as possible! I needed to IIK.

The present invention has been made with attention to the above points, and includes: 1) minimizing the high temperature and high pressure region; 2) cooling the rod by supplying the rod in the opposite direction to the flash flow direction. 3) In order to make the container even smaller and faster, the rods are fed in the axial direction of the container. Through improvements such as: 3) feeding rods in the axial direction of the container, continuous higher speeds can be achieved! In other words, the twist 1w manufacturing method of the present invention continuously supplies rods in the axial direction of a rotating container provided with a plurality of cutting blades. [An orifice consisting of a container and a container] 1# mold is made by continuously cutting wires with a small cross-sectional area and twisting these wires together.

In addition, the rounding device #ItIri of the present invention that implements the above method

The armpit holder 21 is removably attached to an acupuncture groove 211 provided at the tip of the armpit holder 21, and the armpit holder 21 is supported by the twisting die 9 so as to be movable backwards. The cooling device 11B is installed to maintain airtightness of both the twisting plate 1 and the die holder 21], and performs atmosphere adjustment and cooling to prevent scaling of the twisted wires 20. . A part of the cooling medium (g1 element, water, etc.) in this cooling device a18 is connected to the twist plate II.

g5)). Also, a must! Accordingly, the stranded wire 10 is cooled in the die holder 21.

In FIG. 2, when the field and field 2 are pushed into the container 14 by the pinch rolls 6, consideration must be given to the pinch rolls 6 and the container 144C to prevent the field and field 2 from buckling and twisting. - Attaching guides to the rolls, shortening the distance between the final roll and the container, setting the roll shape and rolling blade to prevent twisting, cooling the fourth board, increasing the rotation speed of the container, etc.] adjust. Also, the twisted wire 1 obtained in the 3rd figure
The shape is as shown in FIG. 4, but by changing the twisting die 22, it is possible to easily produce compression-molded twisted strands 1123.

Furthermore, by changing the shape of the cutting edge 25 (FIG. 5), which will be described later, or adjusting the feed amount of the rod 2, it is possible to easily obtain the code 2.
Twisted wires having shapes such as those shown at 6 and 27 can be manufactured.

The XS diagram shows the bond detail diagram of container 14. After the opening and the opening 2 are pushed into a container 14 in which a plurality of cutting blades 25 are installed, they are cut and formed into a strand of 1!20.

That is, the container 14 is connected to the threaded cylinder portion 2 of the hollow adapter 28 which is non-rotatably fitted to the tip of the hollow shaft 15.
A cutting blade holder 2s having a cutting blade 25 therein is connected to the cutting blade holder 2s with a cutting blade 25 inside.

As shown in FIG. 6, this cutting blade holder 29 has a cylindrical body 2s having a screw 29b on its outer periphery, a truncated conical head 2110 at one end of the cylindrical body, and a plurality of blade fitting grooves 29d in the other layer.

The 20 groups of strands pass through the hollow shaft 15 that rotates simultaneously with the container 14, and are combined (1a) by the twisting plate 19 and the twisting die 22 as described above.

FIG. 8 shows a control system diagram for keeping the twisting pitch of the stranded wire 10 constant. The twisting pitch of the stranded wire by the cutting forming machine 7 is determined by the cutting length of the rotation of the container 14, so the cutting amount must be controlled to always be constant in order to keep the twisting stiffness and tension constant. . That is, the rotation of the container 14 may be arbitrarily changed while the feed amount of the vinyl roll 6 is kept constant, or the rotation of the container 14 may be kept constant and the feed amount of the vinyl roll 6 may be arbitrarily changed. However, the latter control method, which is easier to stabilize the device, is used in Part 8.

On the other hand, the Vinci roll 6 is synchronized with a motor 30 via a continuously variable transmission 31, a gear box 36, and a timing belt, and the continuously variable transmission 31 is arbitrarily changed in speed by a pilot motor 35 operated by a command from a control panel 32. can do. That is, the pitch of the stranded wire 10 is detected by the pulse generator 33 and used as a reference voltage, and the rotation speed of the continuously variable transmission output is also detected by the tachogenerator 34, and both are used as the generated voltage in the control panel 32. A command signal is given to the pilot motor 35 to increase or decrease the rotation speed of the continuously variable transmission up to a preset nine ratio.
Therefore, the pitch of the twisted wires is always constant.
