DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a method for producing a flat wire having different vertical and horizontal dimensions in a bar and wire rolling mill. The present invention relates to a method of winding a flat wire used in the method.

[0002]

2. Description of the Related Art When a flat wire having different vertical and horizontal dimensions is manufactured in a bar and wire rolling mill, a flat wire that has been rolled by a finishing mill is output from a pinch roll in a horizontally long direction, and then is fed by a plurality of flat wire guides. It is guided and then wound in a portrait orientation by a poling type winder.

[0003] In this case, using a number of flat wire guides having a fixed shape (for example, an elliptical shape, etc.) flat wire passing portion, a flat wire coming out of a pinch roll in a horizontally long direction is used for a polling type winder. The guide was guided to a nearby position, and the poling type winder was wound in a portrait orientation.

Therefore, the pinch roll is wound by a poling type winder in a portrait orientation by twisting 90 ° flat wires having different dimensions in a landscape orientation.

[0005]

However, in the conventional case, since a large number of flat wire guides having a fixed-shaped flat wire passing portion are used, the flat pinch rolls having different vertical and horizontal dimensions protruding in the horizontal direction are used. Because the twisting direction of the wire cannot be regulated properly, both ends are restricted at the middle of the flat wire, so the flat wire that comes out of the pinch roll in the landscape orientation is a poling type winder. Although it is possible to wind in a vertically long direction at, the twist direction is not specified because the leading and trailing ends of the flat wire are free ends, so the winding direction cannot be regulated. As a result, there is a problem that the defect is caused, and the yield loss at the leading end portion and the trailing end portion of the flat wire is increased. It has been a problem to solve such a problem.

[0006]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned conventional problems, and is intended to restrict not only a middle portion of a flat wire but also a winding direction of a leading end portion and a trailing end portion. A flat wire winding method in which the front end portion and the rear end portion of the flat wire can be wound in a vertically oriented direction with a poling type winder, and the yield loss can be reduced. It is intended to provide.

[0007]

According to the method of winding a flat wire according to the present invention, a pinch roll is wound in a horizontal direction and twisted by 90.degree. In a flat line having different vertical and horizontal dimensions, thereby forming a polling type winding in a vertical direction. When winding in a coil shape by a machine, a plurality of flat wire guides with variable roller spacing are provided between the pinch roll and the poling type winder, from the pinch roll side to the poling type winder side. A plurality of flat wire guide rollers between which the passing material is pinched with a passing material to guide the flat wire while twisting it from the horizontal direction to the vertical direction, and the poling type winder winds the flat line in the vertical direction. It is characterized in that it is configured to be wound in a coil shape.

[0008]

In the method for winding a flat wire according to the present invention,
A plurality of flat wire guides with variable roller spacing are provided between a pinch roll in which flat wires having different vertical and horizontal dimensions are projected in a horizontally long direction and a poling type winder in which the flat wire is wound in a vertically long direction, By pinching the passing material with the rollers of the plurality of flat wire guides between the pinch roll side and the poling type winder side, the flat wire is guided while twisting from the horizontal direction to the vertical direction. Therefore, not only in the middle portion of the flat wire but also in the front end portion and the rear end portion, the pinch roll exits in a horizontally long direction, and after passing through a plurality of flat wire guides, it is gradually twisted in a vertically long direction, When the final flat wire guide exits, the poling winder enters the poling type winder in a portrait orientation, so the poling type winder applies all the front, middle and rear ends of the flat wire. Te becomes possible to be wound in a portrait orientation, so that the occurrence of yield loss in the tip portion and the rear end portion of the Tairasen is avoided.

[0009]

1 to 3 show one embodiment of a method for winding a flat wire according to the present invention. In the case where flat wires having different vertical and horizontal dimensions are manufactured in a bar and wire rolling mill, the finishing is performed. A case where the flat wire that has been rolled by a rolling mill is used to wind up a coil will be described.

As shown in FIG. 1, a flat wire 1 that has been rolled by a finishing mill is guided by a number of flat wire guides 3a, 3b,. Then, it is gradually twisted in a vertically long direction, and is wound in a coil shape in the vertically long direction in the poling type winder 4.

The plurality of flat wire guides 3a to 3a
Of the v, the fourth, twelfth, and eighteenth flat line guides 3d, 3l, and 3r use flat line guides with adjustable roller spacing, and other flat line guides 3a to 3r.
For c, 3e to 3k, 3m to 3q, and 3s to 3v, those having a fixed shape flat line passing portion are used.

FIGS. 2 and 3 show the flat wire guides 3d, 3l, 3r with variable roller spacing. The flat wire 1 enters the trumpet 10 from the direction indicated by the arrow in FIG.

The flat line guides 3d, 3l and 3r have upper and lower rollers 11 and 21, respectively.
1 is rotatably supported by a fixed roller holder 16 by a bearing 12, a lower roller shaft 13, a bush 14, a grooved nut 15, and the like.

The upper roller 21 is supported by a lifting roller holder 26 by a bearing 22, an upper roller shaft 23, a bush 24, a grooved nut 25 and the like so as to be able to move up and down.

In this case, the upper roller shaft 23 passes through vertically long holes 16a and 16b formed in the fixed roller holder 16, and an air cylinder 27 is fixed to the upper surface of the fixed roller holder 16 by bolts 28. The piston shaft 27a of the air cylinder 27 is fixed to a lifting roller holder 26 by a nut 29 and can be raised and lowered.

That is, air is supplied and exhausted through the air supply port 27b and the air discharge port 27c of the air cylinder 27,
As a result, when the piston shaft 27a is raised, the lifting roller holder 26 is raised to the imaginary line position, whereby the upper roller shaft 23 is raised in the vertically long holes 16a, 16b, and the upper roller 21 is also raised, and the upper and lower rollers are raised. The interval between 11 and 21 increases.

Conversely, by lowering the piston shaft 27a, the lifting roller holder 26, the upper roller shaft 23,
The upper roller 21 and the like descend, and the distance between the upper and lower rollers 11 and 21 decreases, thereby pinching the passing material.

Therefore, by gradually changing the roller spacing of the flat wire guides 3d, 3l, 3r with variable roller spacing, the flat wire 1 which has come out of the pinch roll 2 in the horizontal direction is changed from the horizontal direction to the vertical direction. The flat wire 1 is wound into a coil shape by the poling type winder 4 in a vertically long direction while being guided while twisting.

As shown in FIG. 1, in the poling type winder 4, a flat wire winding space 43 is formed between an inner frame 41 and an outer frame 42, and the flat wire 1 has an annular flat wire winding shape. It enters into the take-up space 43 at an inclination angle of about 45 ° from the tangential direction and is wound into a coil.

Therefore, when winding the flat wire 1 that has come out of the pinch roll 2 in a horizontally long direction into a coil shape in a vertically long direction using a poling type winder 4, first, a flat wire guide with a variable roller interval is used. In each of 3d, 3l and 3r, the piston shaft 27a of the air cylinder 27 is raised to maximize the interval between the rollers 11 and 21, and each of the flat wire guides 3d, 3l and 3r immediately after the tip of the flat wire 1 passes. Supply / exhaust air to / from the air cylinder 27, the upper roller 21
Are sequentially lowered and pinched by a roller, and the flat wire 1 is guided while being twisted from the horizontal direction to the vertical direction, so that the poling type winder 4 can be wound in the vertical state.

After the winding of the flat wire 1 in the longitudinal direction is sequentially performed, the rear ends of the flat wire 1 are flat wire guides 3a to 3a.
Immediately before passing through v, in the flat line guides 3d, 3l, 3r with variable roller spacing, the piston shaft 27a is raised to sequentially maximize the roller spacing.

By doing so, the flat wire 1 that exits the pinch roll 2 in a horizontally long direction is guided while the twist direction is regulated by the flat wire guides 3d, 3l, 3r with variable roll spacing, and polling is performed. The winding direction of the flat wire 1 is regulated not only at the middle portion but also at the front end portion and the rear end portion of the flat wire 1 so that the winding direction is regulated. Irregular torsion does not occur in the part, and the yield loss is small.

[0023]

According to the method for winding a flat wire according to the present invention,
Between the pinch roll and the poling type winder, a plurality of flat wire guides with variable roller spacing are provided, and between the pinch roll side and the poling type winder side, the plurality of flat line guide rollers are provided. Since the flat wire is wound by a poling type winder in the portrait orientation while guiding while twisting the flat wire from the landscape orientation to the portrait orientation by pinching the passing material, By regulating the winding direction of the front and rear ends as well as the middle part of the flat wire, the front and rear ends of the flat wire can be wound vertically by the polling winder. It is possible to achieve a remarkably excellent effect that the yield loss can be reduced.
