Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a wire laying device for forming a wire into a coil. The present invention can be used in a laying device that bends a wire made of general steel, stainless steel, special steel, etc. into a coil shape.

[Prior Art] This wire rod laying device is formed by bending a continuous pipe so as to be continuous from the apex of the cone to the bottom edge of the cone, as in the substantially conical slope of the cone. Then, while rotating the continuous pipe at high speed around the axis of the cone, the wire is introduced from the inlet of the continuous pipe,
The wire W led out from the outlet of the continuous pipe is continuously bent into a coil shape. However, since the wire W is violently rubbed by the inner circumferential wall of the continuous pipe, there is a problem in that the surface of the wire W is burned and a first stage occurs.

In addition, as a special laying device, JP-A-58-318
There is one shown in Publication No. 64.

The laying neck of this wire is carried out from the apex 105b of the imaginary cone 105 to the bottom edge 105c of the imaginary cone 105, as shown in FIGS. up to the straight short cylinder 106
It is constructed by consecutively arranging the V-shaped parts at intervals with slightly different angles. As shown in FIG. 12, a rotatable guide roller 107 is provided at the tip of each short cylinder 106.
．． 108, 109, are arranged in three directions.

Then, the wire rod W is conveyed by a pinch roller or the like, and the wire rod W is passed through the wire rod guide 110 arranged in front of the wire rod laying device, and the wire rod W is inserted into each short cylindrical body 106. In addition, the wire laying device is rotated at high speed around the axis of the virtual cone 105, thereby coiling the wire W led out from the rear short cylinder 106. It is decided to bend continuously.

By the way, in the above-described wire rod laying necking, the curvature of the wire rod laying device as a whole must be ensured by gradually shifting the angle of the straight short cylinders 106 at predetermined intervals. As the wire rod W slides through the straight short cylinder body 106, the wire rod W is rubbed violently by the inner circumferential wall of the short cylinder body 106, and as a result, the wire rod W is burned onto the surface of the wire rod W.
There is a problem with scratches. In particular, the wire W is heated at 100m/se.
When the wire is passed through the wire at a high speed of about c, the problem of burning and scratches on the surface of the wire W is serious. In addition, when the wire W passes through the short cylinder 106 immediately after being hot-worked to have a predetermined diameter, the wire W has heat, so seizure occurs between the wire W and the short cylinder 10G. is likely to occur.

[Problems to be Solved by the Invention] The present invention has been made in view of the above-mentioned problems, and its purpose is to provide a wire laying device that can reduce burning and damage to the wire.

[Another Means for Solving the Problems] The wire rod laying device according to the present invention uses a continuously extending wire rod laying head pipe, and a guide roller is arranged in the side hole of the wire rod laying head pipe. It is characterized by

That is, the wire laying device according to the present invention includes a base;
An inlet that continues from the apex of the cone to the bottom edge of the cone as in the substantially conical slope of the substantially cone, and an inlet through which the wire is introduced to the If point of the cone, and an outlet through which the wire is led out to the bottom edge of the cone; A wire laying head pipe is formed with a guide hole connecting the inlet and outlet, and is held on a base so as to be rotatable around the axis of the cone. In the wire rod laying device, the wire rod laying head pipe includes a pipe body having an inner circumferential wall that partitions most of the guide hole and a side hole provided in a part of the inner circumferential wall, and a side hole of the pipe body. The guide roller is provided in the hole, the roller partitions a part of the guide hole, and the guide roller is rotated by a wire passing through the guide hole.

The base rotatably holds the wire laying head pipe.

The wire laying head pipe has a long cylindrical shape through which the wire passes, and continues from the apex of the virtual cone to the bottom edge of the cone, just like the substantially conical slope of the virtual cone. The wire laying head vibrator has an inlet at the apex of the cone through which the wire is introduced, an outlet through which the wire is led out at the bottom edge of the cone, and a guide hole connecting the inlet and the outlet.

The wire laying head pipe is formed of a pipe body that forms most of the guide hole and has a side hole in a part of the peripheral wall, and a rotatable guide roller disposed in the side hole of the pipe body. The main body of the vibrator is usually formed as a round vibrator.

As mentioned above, the wire rod laying head vibrator is curved and continuous from the apex of the virtual cone to the bottom edge of the virtual cone, as in the substantially conical slope of the virtual cone. When the wire passes through the guide hole, a portion with a large degree of laminar movement and a portion with a small degree of sliding occur.

The side hole for arranging the guide roller is usually formed at the back of the pipe body of the radvib for wire laying, in a part where the degree of sliding with the wire is large. Forming in this manner is advantageous in suppressing seizure and damage to the wire.

Therefore, it is desirable to form a side hole in a portion where the pipe body of the wire laying head pipe is largely curved, and to arrange a guide roller in the side hole at -. The mounting structure of the guide roller can be selected as appropriate. In this case, Guy 1
:The roller can also be installed so that it can move freely in the axial direction of the pipe body. The guide 1 cola has a structure that can be freely replaced with respect to the pipe body of the wire laying head pipe. By shifting in this manner, the guide roller can be replaced when the roller surface of the guide roller becomes worn out. Select the guide roller size, ill't fill, etc. as appropriate.
Ru.

The guide roller can be cylindrical or spherical, or later)!
As shown in the embodiment, it may be in the shape of a bundle.

The guide roller may be hollow in order to reduce the weight.

Guide 1 cola can be made of metal materials such as steel and aluminum alloys, or ceramic materials such as alumina and silicon nitride.The roller surface of the guide roller is made of tungsten carbide, alumina, zirconia, silicon nitride, silicon carbide, etc. It is also possible to form an I!J resistant layer of titanium carbide or the like.

In this case, the wear resistance of the roller surface can be improved.

The wear layer can be a molten tA layer. Further, the roller surface of the guide roller can be coated with a solid lubricant layer formed of a solid lubricant such as carbon, disulfide-libdenum, fluorinated graphite, boron nitride, or fluororesin. In this case, lubricity can be ensured. The solid lubricant layer may be formed of a composite material reinforced by mixing a solid lubricant with fibers such as carbon fiber N. The direction in which the fibers are oriented is preferably the direction in which the wire passes, in order to ensure the passage of the wire.

The angle of the guide roller can also be adjusted as appropriate with respect to the pipe body. In this way, by adjusting the angle of the guide roller according to the sliding resistance when the wire passes through,
This is advantageous for ensuring the passage of the wire rod. In order to ensure cooling performance of the guide roller, a cooling vibrator may be embedded in the guide roller.

As the drive unit, a known drive unit can be used, such as an electric motor or a hydraulic drive unit. Considering that the wire laying head pipe is rotated at high speed, ′? A Pi rib motor is preferred.

In the laying device according to the present invention, in addition to arranging guide rollers in the side holes of the pipe body, if necessary, a large number of vibrators and rings whose main component is a solid lubricant are fitted in series in the pipe body. It may be crowded.

In a special case, a large number of air jet holes are formed in the wall of the pipe body of the wire rod laying head pipe, and the air jet holes are connected to a fluid supply device such as a compressor, and the guide holes of the wire rod laying head pipe are connected to the wire rod laying head pipe. If the structure is such that air is ejected from the air ejection hole toward the KA 44 when the wire passes through, it is easy to secure the required gap between the inner circumferential wall of the pipe body of the wire laying head pipe and the wire, This is more advantageous in terms of suppressing scratches on the wire. This air is normally discharged to the outside air from the outlet of the wire laying head vibe. It is preferable to form the air outlet in a place where the wire is likely to be burned and damaged.

[Operation] In the wire rod laying device according to the present invention, the wire rod laying head vibrator is rotated about the axis of the cone by the driving section. Then, while rotating the wire laying head pipe, the wire is introduced from the inlet. Then, the wire passes through the guide hole and is bent into a coil as in the conventional method.

As described above, when the FA material passes through the guide hole, the outer surface of the wire comes into contact with the roller surface of the guide roller, and the friction force causes the guide roller to rotate. Since the guide roller rotates in this manner, the sliding resistance between the IG and the wire laying head vibe is reduced.

It is said that

As shown in FIG. 2, the wire laying head pipe 17

is retained. The wire laying head pipe 17 is inserted into the hole 10a of the cylindrical body 1o, and the pipe body 21 on the one outlet side extends around the outer periphery of the cylindrical body 10 in a slightly spiral shape and is held by the fin portion 16. And the second
As shown in the figure, the outlet 19 side of the wire laying head pipe 17 is fitted into the groove 24a of the U7 plate 24, and the spacer 40 is inserted into the groove 24a1. : Fit together, insert the pin 41 into the mounting hole of the U7 plate 24, and fix the pin 41 with the washer 43 and pins 1 to 42. This U7 plate 24 is attached to the base 2 via other members, although not particularly shown.

As a result, as in the conventional case shown in FIG.
continues from the apex of the virtual cone 22 to the bottom edge of the virtual cone 22, and an inlet 18 is located at the apex of the virtual cone 22, and an outlet 19 is located at the bottom edge of the virtual cone 21. Here, the wire laying head pipe 17 is rotatable around the axis of the imaginary cone 21, that is, around the axis of the cylindrical body 8.10.

Here, when the drive motor 15 rotates, its rotational force is transmitted to the gear 13 via the shaft 12, the gear 13 rotates in the direction of arrow B, and therefore the gear V14 rotates, the cylinder 8 rotates, and the wire rod Laying head pipe 17 is arrow F
Rotate in the direction. Note that in this embodiment, the guide roller 3
One material is 5UJ2.

As shown in FIG. 5, in front of the wire rod laying device 1, a wire rod finish rolling device 25, a water cooling zone 26, a driven roller 27, a pinch roller 28, and a wire rod guide 29 are arranged. A cooling conveyor 30 is arranged at the rear of the device 1. The wire guide 29 is
As shown in FIGS. 6 to 9, it is formed of an outer vibe 31 and a lubricating vibe 32 held inside the outer pipe 31 by screws 33. The outer pipe 31 is made of metal. The lubricating vibe 32 is made of carbon. The lubricating vibrator 32 is formed with a guide portion 34 whose inner diameter gradually increases. A groove 35 is formed in the inner peripheral wall of the outer vibrator 31 to prevent rotation. Note that the groove 35 may not be formed.

A stopper part 36 is attached to the end of the outer vibrator 31.

Now, the case where Laying II according to this embodiment is used will be explained. First, the wire rod W hot-rolled by the wire rod finish rolling device 25 is pulled by the pinch rollers 28. Then, the wire rod W is cooled to about 800 to 1000°C in the water cooling zone 26, and the wire rod W is inserted from the guide portion 34 side of the wire rod guide 29 via the driven roller 27, and is inserted into the inner peripheral wall of the lubricating pipe 32 of the two wire rod guides. The wire is fed lfi while being in contact with the wire rod, and further reaches the wire laying device 1.

Then, the wire W enters the guide hole 20 from the inlet 18 of the vibe body 21 of the wire lay ink head vibe 17 of the laying device 1, passes through the guide hole 20, and exits from one outlet of the pipe body 21. It is discharged towards the direction. At this time, the wire rod laying vibrator 7 is rotated at 230 to 1500 revolutions per minute about the axis of the cone 22 by the rotation side FiJ of the drive motor 15. As a result, the wire W fed into the wire laying head pipe 17 is continuously bent into a coil shape and discharged from one outlet. The wire W bent into a coil shape is conveyed to a predetermined location by a cooling conveyor 30.

By the way, the guide roller 39 is rotated by the I'JtH force with the wire W. Therefore, the one-strain resistance of the wire W can be reduced.

In this embodiment, the pipe body 21 through which the wire rod W passes is continuous from the inlet 18 to one outlet.

Therefore, the curvature of the pipe body 21 can be changed little by little. Therefore, the surface of the wire rod W is less likely to be scratched compared to the conventional structure in which the straight short cylinders 106 are arranged in a row with predetermined intervals and are shifted little by little. Of course, since the guide roll 22 rotates upon contact with the wire rod W, the wire rod W passing through the guide hole 20 of the pipe body 21 of the wire rod laying head pipe 17
and the inner surface of the wire laying head vibrator 17.
Habits can be reduced or eliminated.

Further, in this embodiment, the roller surface 22 of the guide roller 22
Since the roller a is coated with a wear-resistant layer made of tungsten carbide, it is advantageous in preventing wear of the roller surface 39a.

FIG. 10 shows another embodiment of the invention. In this example, the wire laying head pipe 17 is fitted into the groove 24a of the U-shaped plate 24, and the threaded portion 52a at the tip of the bottle 52 passed through the hole 24e of the U-shaped plate 24 is inserted into the U-shaped plate 24. 24 into the dovetail hole 24f, and thereby arrange the guide roller 39 in the side hole 21b of the wire laying head pipe 17.

[Effects of the Invention] According to the wire laying device according to the present invention, the sliding resistance of the wire can be reduced (q) by rotation of the guide roller, and seizing and curling of the wire can be suppressed.

In addition, in the wire rod lay ink device according to the present invention, since the pipe body of the wire rod lay vibrator is continuous with a constant curvature from the inlet to the outlet, the straight short cylindrical body 106 is used as shown in FIG. Compared to the conventional method, which ensures curvature as a whole, H is less likely to form on the surface of the wire.
