When producing a flat stranded wire as a superconducting stranded wire using a wire twisting machine, as shown in FIG. The strands pass through the collecting plate 1b and are collected in the hole of the collecting die 3, which has a rectangular hole shape with a nipple 6 having a rectangular tip as a guide, and are collected while making a circular motion based on the rotation of the stranding machine 1. A large number of core wires 2 are twisted together in a vertically and horizontally aligned manner in a hole shape with a rectangular cross section in a collective die to form a flat twisted wire 10 that essentially does not involve compression molding, and then the die is removed. The resulting flat stranded wire 10 is sequentially compressed in the upper and lower directions by a pair of compression rolls 4 1 facing each other vertically, and compressed in the left and right directions by a pair of compression rolls 4 2 facing left and right. Finishing compression processing is performed using Turks head rolls 5, which are arranged in four directions on the surface and combined to form rectangular forming passage holes, to produce stranded superconducting wires 10' having predetermined dimensions and density. Was. Note that 2' is the finished shape of the core wires 2 assembled and twisted by the assembly die 3 after compression processing.

As such a gathering die 3, polyether resin or UD, which was conventionally known under the trade name of Zyuracon, can be used.
It was manufactured using hard plastic such as nylon (trade name) or wood, but when the cores are assembled, abrasion occurs particularly at the twisting opening on the core wire insertion side, causing the die hole shape to collapse, and a large amount of damage is caused by such wear. It was not possible to produce a satisfactory flat stranded wire because the scum got into the valleys between the stranded core wires.

断線してしまう現象が生じ、失敗に終わつた。 The inventors made such dies from a hard-to-wear metal, such as a cemented carbide such as Tungaloy (trade name), and tried to use this to create collective twisting, but while the dies did not wear out, they did not result in collective twisting. A large number of core wires may not be properly aligned vertically and horizontally within a hole with a rectangular cross section, resulting in some of the core wires being disorganized and crossing each other, or some of the core wires may be damaged. In addition, along with these phenomena, it became difficult to pull out the wires from the assembled die in the twisted state, and if an attempt was made to forcefully pull them out, the core wires would break at the twisting end, resulting in failure.
考案者等は、上記のように心線が傷や断線に至
るメカニズムを解析した結果、次のような原因に
基づくものであることを突き止めた。 As a result of analyzing the mechanism by which the core wire becomes damaged or disconnected as described above, the inventors discovered that the cause is as follows.

いたのである。 In other words, a large number of bobbins attached to a cage are moved in a circular orbit around the rotational axis of the cage, so that the core wire drawn out from each bobbin is rotated in a circular orbit while passing through the rectangular hole of the collecting die. However, when the wires are gathered and twisted in the rectangular die hole, the core wires are vertically dislocated and twisted on both short sides of the rectangular die hole's twisting opening. The short edge forming part of the stranded wire that is being inserted is not easily inserted into the die hole, and the twist accumulates on the core wire that is about to enter the die hole (the core wire gets stuck at the twisting opening). As a result of this phenomenon, the core wires cross each other or are damaged, and the friction between the die hole and the twisted core wires becomes too large, causing a pull-out force in front of the die. This caused large tension to be applied to the wires, causing the wires to break.

造用の集合ダイスを提供することに目的がある。 The present invention solves the problems of the conventional technology as described above, and manufactures a flat stranded wire in which a large number of core wires fed out from a stranding machine are arranged vertically and horizontally in a rectangular cross section, assembled, and twisted. In the set of dice,
A set of dies for producing flat stranded wires that significantly improves its own lifespan and can produce long lengths of high-quality flat stranded wires without damaging or breaking the stranded core wires. There is a purpose in providing.

The assembled dice of the present invention that achieves this purpose are:
It consists of a twisting opening provided on the stranded core wire insertion side and a straight section extending from the twisting opening to the stranded cored wire exit side, and the straight part is made of a plastic cylinder. A through hole with a rectangular cross section is formed in the straight part, and one twisting part is made of a short cylinder made of cemented carbide, and the shape of the twisting opening is on the rear end side which is connected to the through hole of the straight part. The hole gradually expands from the hole to the end of the stranded wire insertion side, and the rectangular hole has a rounded shape as a whole so that both short sides of the hole bulge out on the stranded wire insertion side. The shape of the hole is configured so that the shape of the hole converges with the hole on the rear end side.

To explain the situation of wire twisting in the above-mentioned collecting die of the present invention, a large number of core wires are fed out from the bobbin of the wire twisting machine, and together with the bobbin, which moves circumferentially in a circular orbit based on the rotation of the wire twisting machine. At that time, the pieces are gathered together with a circumferential movement in a circular orbit, and at that time, from the circumferential movement in a circular orbit, they are gathered into a rectangular shape and arranged vertically and horizontally, and are twisted into the twisting hole of the gathering die. Then, by sliding through the through holes of the straight part, the wire is pulled out from the straight part as a flat stranded wire that is not substantially subjected to compression processing while maintaining the twisted state in a rectangular shape, and is then subjected to compression processing in the subsequent stage. It will be transferred to the process.
しかして、集合ダイスは、心線を撚り込む撚口
部を超硬合金により製作してあるので、その撚口
穴が摩耗して変形するようなことが無くなる。 Since the collecting die has a twisting opening for twisting the core wires made of cemented carbide, the twisting opening is prevented from being worn out and deformed.

つていた撚口部で心線の撚りが溜まるような現象
が生ずることが無くなる。 In the process of entering the twisting hole in the twisting part made of cemented carbide, the large number of core wires
Twisting is started from the gourd-shaped part, which has a hole shape based on a rectangle at the end of the core wire insertion side and has a rounded shape with both short sides bulging, to the rear end side where the shaped part gradually converges. Because of this, the upper and lower dislocation twists required on both short sides in order to form a rectangular shape and twist them in a vertically and horizontally aligned state are caused by the swollen portions on both short sides of the gourd-shaped part. This is done smoothly while rotating, and therefore, the phenomenon in which the twist of the core wires accumulates at the twisting end, which has been a problem in the past, does not occur.

り撚合せ中の心線が断線することもなくなる。 In addition, the core wires, which are twisted at the twisting end and arranged vertically and horizontally in a rectangular shape as described above, can be inserted into the rectangular through hole in the straight part of the hard plastic while maintaining the twisted state. Since the twisted core wires are passed through while sliding, the twisted core wires are not subjected to large friction and can be easily pulled out toward the front of the die without large pulling resistance. There will be no possibility of the core wire breaking.

過できるように縦横の幅を選定してある。 Thus, the cluster die 3 is constructed by connecting a twisted end part 7 and a straight part 8 of the core wire in a square hole 3b of a half-split die casing 3a. It is made of hard plastic such as nylon and shaped into a rectangular tube shape, and has an outer shape that matches the rectangular hole 3b of the die casing 3a so that it can be fitted into the die casing 3a. , a through hole 8a with a rectangular cross section is formed, and the through hole 8a is arranged vertically and horizontally so that a flat stranded wire in which a large number of core wires are gathered and twisted, but which is not substantially subjected to compression processing, can pass through the through hole 8a. The width is selected.

うになつている。 One of the twisting openings 7 is made of a cemented carbide such as Tungaloy (trade name) and shaped into a short cylinder, and has a rectangular hole 3c on the wire insertion side of the die casing 3a.
The casing 3a has an outer shape corresponding to
It is designed to be set in a fit-in manner, and a twisting hole 7a for twisting the core wire is formed. This twist hole 7a forms a hole 7b connected to the through hole 8a of the straight portion 8 on the rear end side, and gradually expands from the hole 7b to the end on the core wire introduction side. However, on the core wire introduction side, a gourd-shaped part 7c is formed, which is based on a rectangular hole shape and rounded as a whole so that both short sides thereof bulge, and the rear end where this shaped part 7c extends. The hole 7b is gradually narrowed so as to converge on the hole 7b.

埋め込みハンダ付けされるため、圧縮加工による
成形形状には正確な長方形形状が要求される。 However, in the case of superconducting stranded wires, since they are embedded in stabilized copper and soldered, the molded shape by compression processing requires an accurate rectangular shape.
