Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a twisting method and a twisting apparatus for a deformed wire having a non-circular cross section and a directivity.

[0002]

2. Description of the Related Art FIG. 5 shows, as a conventional example, a twisting device for obtaining a non-circular electric wire 7 having a steel core aluminum stranded wire as a base and having protrusions at the top and bottom in a transverse section. In this twisting device, a press roll 2 is attached above and below a collecting plate 1,
The diffuser plate 3 and the assembly die 5 are sequentially arranged on the downstream side. Reference numeral 4 denotes a diffusion tube that fixes and supports the collecting plate and the diffusion plate 3 at a specific position. Therefore, the deformed wire 6 made of aluminum and having a non-circular cross section is pressed by the pressing roll 2 arranged on the front surface of the collecting plate, passed through the hole 31 of the diffusion plate 3 on the downstream side thereof, and then twisted together into the collecting die 5. Was.

By the way, the presser roll 2 has a pair of grooved rolls 21 and 21 so as to surround the irregular shaped wire 6 from above and below.
And is mounted on the collecting plate 1 in accordance with the number of twisted wires of the odd-shaped wire 6. When the atypical aluminum wires twisted with each other are different and have different rigidity, the twist amount is changed according to the rigidity. At that time, since the upper and lower presser rolls 2 are used, only adjustment of twist in every 180 ° is required.

The diffuser plate 3 is used to stably insert the irregular shaped wire 6 into the assembly die 5. By passing the diffusion tube 4 into the inner wire for twisting the irregularly shaped wire, more stable assembly is possible. In order to stabilize the irregular line 6 by the diffusion plate 3, the diffusion plate 3 is adjusted to move between the diffusion tubes 4.

[0005]

The above-mentioned conventional twisted wire technique for atypical wires has the following problems. Since the upper and lower presser rolls have a special groove shape corresponding to the irregular line, a roll is required for each type of irregular line. A collecting plate is also required for each number of twists. Assembling a collecting plate and a presser roll is required for each size of the irregular wire, which requires setup time. In the above-mentioned press roll type, the plastic deformation of twisting is not given to the deformed wire itself, which is the strand, and the plastic deformation is given by the assembly die, so a large die pressing pressure is required at the time of twisted wire forming, and the inner layer is nicked. growing. In the case of twisting different types of wires with different rigidity, the twist can be adjusted only every 180 °, and the twist amounts do not match.
Adjustment with the diffuser takes time.

In view of the above-mentioned problems of the prior art, the present invention can be commonly used for each size, the number of twists and the twist can be easily adjusted, and a certain degree of plastic deformation can be preliminarily added.
An object of the present invention is to provide a twisted wire method and a twisted wire device for irregularly shaped wires, which contributes to reduction in setup time and device cost.

[0007]

According to the method of twisting atypical wire provided by the present invention, the pressing portion is made a separate type corresponding to the number of twists, and the atypical wire is formed by three-stage rolls arranged in zigzag for each separate type. While holding it while sandwiching it, twisting is applied to the profile line by the 4th stage roll, and the diffusion plate can be moved back and forth along the profile line supply direction and the passage position of the profile line can be changed in the radial direction. It is a method of passing a wire.

Further, in the twisting device for atypical wire provided by the present invention, the pressing portion is a separate type according to the number of twisted wires of the atypical wire, and each separation type has a zigzag-arranged three-stage roll as a main body of the pressing portion and four rolls. The diffusing plate has a twisting roll at the stage and is capable of reciprocating itself along the profile line supply direction, and at the same time, the profile line passing position can be varied in the radial direction.

In a preferred embodiment of the above twisted wire device, the diffusing plate is itself supported by a diffusing tube which is capable of expanding and contracting in the direction of feeding the modified wire, and has a three-stage hole extending in the radial direction at the position where the modified wire passes. Is. Further, each separation type support base of the pressing portion is constituted by a guide plate fixed on the collecting plate and a rotating plate pivotally supported by the guide plate, and supports the guide roll on the guide plate. In addition, the third stage roll and the fourth stage roll are supported on the rotating plate. Further, the guide plate is provided with removable mounting legs on the periphery of the collecting plate.

[0010]

According to the method and apparatus for twisting atypical wire according to the present invention, a three-stage roll having a zigzag arrangement is used as the main body of the pressing portion to press the atypical wire while giving directionality to the zigzag arrangement. The position of the corrugated rolls, for example, the position of the roll of the second corrugation, can be adapted to the irregular lines of each size. In order to correspond to each number of twists, the pressing part of the irregularly shaped wire can be attached and detached as a split type, and the even number of twists can be arranged. Since the deformed wire is twisted by the fourth roll and plastically deformed in advance, the load on the assembly die can be reduced. Further, since the amount of twist can be freely changed for each irregular wire, various irregular wire mixed twists are also possible.

In addition to the above-mentioned pressing portion, the diffusing plate can be reciprocated along the feeding direction of the profile line, and the passing position of the profile line can be changed in the radial direction. No replacement is required and setup time can be reduced.
