Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a wire guiding method for a wire winding device, and in particular,
Suitable for use in wire rod rolling installations with stelmore lines, horizontally transported wire rods are transported by a chain wrapped between wheels or by a number of guiding rollers.
The present invention relates to an improvement in a method for guiding a wire in a wire winding device in which the wire is brought into pressure contact with a main wheel, changes direction in the vertical direction, and is guided to a wire winding device.

Generally, in a wire rod rolling installation having a stelmore line for directly heat-treating the wire rod, as shown in FIG. For example, a pair of rotatably driven grooved main wheels 16 and a freewheel case 18c rotatably supported by a free wheel case 18c for drawing in the wire rod 10 and pressing it against a 1/4 circumference of the main wheel 16. Wrapped between IJ-Heuherl 18a and b,
A wheel that rotates together with the main wheel 16: [
- cone guide 22 for guiding the wire rod 10 whose direction has been changed in the vertical direction by the 1/4 circumference of the main wheel 16 to a loading type laying type cone 24 which is a wire H winding device. J2 is attached to the chain guide type feed guide 14, 1. / - is guided to the laying type cone 24, wound up into a ring shape by the laying type cone 24, and conveyed on the C1 Stelmore conveyor 26 while being spread out on a plane in a non-concentrically overlapping state, and is forcedly cooled. There is.

Conventionally, in the feed guide 14 of such a wire rod rolling equipment, the chain 20 is connected to a frill wheel 18a.
Simply pressurize, for example by compressed air, via s b! ii) Since the air cylinder was crimped onto 1/4 of the circumference of the main wheel 16 with a constant pressure, and the positional relationship between the freewheel 18a1b and the main wheel 16 was always fixed, the wire rod 10 If the angle of approach of the wire 10 to the cone guide 22 changes depending on the diameter or longitudinal position, the wire 10 may not be guided smoothly.

That is, for example, when the maximum rolling speed is 5.5〆, 40η
In the case of a wire rod rolling mill of '7 S e C, when the diameter of the wire rod 10 is 70 or less (for example, 5.5y to 796 mm) and the rolling speed is relatively high, when the tip of the wire rod 10 passes, VC1
As shown in FIG. 2, the tip of the line IJ'IO sometimes hit point A on the front (left side of the figure) wall of the upper cone guy 22, causing a misroll. On the other hand, when the diameter of the wire rod 10 is 896 mm or more (for example, 896 to 120 mm) and the rolling speed is relatively slow, the tip of the wire rod 10 passes through the cone guide 22 as shown in FIG. At the rear (right side of the figure), there were cases where the product accidentally hit point B on the wall surface and caused a burnt stain roll.Also, when winding up the main body of the wire rod 10 with the 1/- ing type cone 24, the As shown in Fig. 4, the wire rod 10 is loose as shown by arrow C between the exit side of the main wheel 16 and the cone guide 22, and this bends, causing misroll.・Ha, cone guide 2
The life of the silicone guide 22 is shortened due to wear due to constant contact of the wire rod 10 with the specific splicing point of 2, and scratches are added to the wire rod 10 due to protrusions generated at the worn portion, resulting in damage to the product. There were problems such as a decline in quality.

The present invention has been made to solve the above-mentioned conventional drawbacks, and it is possible to optimally maintain the angle of entry of the wire into the cone guide regardless of changes in the diameter or longitudinal position of the wire. It is an object of the present invention to provide a wire guiding method for a wire winding device that can prevent misrolls, shortened cone guide life, and product quality.

The present invention changes the direction of a horizontally transported wire rod vertically by pressing it against a main wheel using a chain wrapped between wheels or a large number of guide rollers,
In the wire drawing method of the wire winding device which is designed to avoid the wire winding device, at least the exit wheel or the final guiding roller is movable in the horizontal direction, and the exit wheel or the final guiding roller is movable in the horizontal direction. The above object is achieved by changing the position according to the diameter of the wire, the position in the longitudinal direction, etc.

Further, the horizontal position of the exit wheel or the final guide roller is set so far away from the main wheel that the diameter of the wire becomes a dog.

Alternatively, the horizontal position of the exit wheel or the final guide roller is made closer to the main wheel when winding up the main body of the wire than when passing through the tip.

Furthermore, the smaller the diameter of the wire, the greater the distance to which the wire can be brought closer to the main wheel.

The present invention was developed by the inventors in the process of investigating the material and the amount of wear as a countermeasure against wear of cone guides, and noticed that the wear points differ depending on the product size. It is important as a countermeasure against misrolls and product scratches, and in a chain guide type feed guide in which the wire is pressed against the main wheel by a chain wrapped between the wheels, the t-nig, the entire freewheel, or the outlet hole is・By moving the r-ru in the horizontal direction, on the other hand, in a wheel guide in which a large number of guide rollers are pressed against the main wheel, by moving the final guide roller in the horizontal direction. This method was developed based on the fact that it is possible to change the angle at which the wire enters the cone guide.
