Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a wire coil focusing device, and more particularly to a wire coil focusing device with less occurrence of flaws.

In recent years, various efficient methods have been adopted as methods for producing steel wire rods, in which a wire rod rolling process and a subsequent heat treatment process are directly connected.

In this method, the wire rod exiting the final rolling mill passes through a water cooling device, is made into a ring shape by a laying type winder, and is dropped onto the next conveyor (chain conveyor, roller conveyor, etc.), and each ring is passed on the conveyor. The wire rods are conveyed while unfolding in a non-concentric polymerized state, and after being cooled at the desired cooling rate during conveyance, they are bundled into a wire convergence device (convergence tab, convergence carrier) at the end of the conveyor, and transferred to the next process. It consists of

The bundled wire rod coils are then subjected to inspection, weighing, and other processes at another location, and finally bundled, and then loaded onto a suitable means of transportation and shipped.

Naturally, coils shipped as finished products are required to have as few defects as possible in terms of quality, and for this reason various improvements have been made to reduce the occurrence of defects in the manufacturing process of wire rods. This problem can occur due to various causes even after focusing, and the reality is that in the past, almost no effective measures have been taken to prevent the occurrence of flaws after focusing.

In other words, when we examine in detail the occurrence of flaws after coil focusing, we find that the causes of flow are contact between the binding hoop material and the coil, contact between the coils, contact between the coil transfer hook and the coil, and contact with the focusing carrier. etc.

In addition, in the wire coil 2 directly bound with the binding hoop material 1 shown in Fig. 1, the occurrence rate of flaws at both ends of the coil (a, l) accounts for nearly half of the total. It became clear.

This flaw on both ends of the coil is caused by contact between the hoop material and the coil.
Contact between the coils (when the coils are stacked) and hooks caused by the hooks are thought to be caused by the following reasons.

In view of the above points, it is an object of the present invention to provide a wire coil convergence device that can prevent the occurrence of flaws on both end faces of the coil and thereby improve the quality of the wire.

Another object of the present invention is to provide extremely efficient wire coil focusing equipment (process) that can easily incorporate a flow prevention process without any changes to the conventional wire focusing process. be.

Therefore, the focusing device of the present invention, which is distantly related to this purpose, is equipped with two coil end face protection materials at the focusing position before and after the wire material is focused, and both end faces of the coil are covered with these protection materials. It is characterized by being coated.

In other words, the specific configuration of the present invention is to provide a protective material supplying material that is provided below the terminal end side of a conveyor that conveys wire rods in a non-concentric polymerized ring state, approximately parallel to the conveyor, and whose tip is provided in a wire rod fall guide tube whose tip is at the end of the conveyor. a guide plate attached to the mouth position; a protected forest extrusion plate disposed on the rear end side of the guide plate so as to move forward and backward along the surface of the guide plate;
A protective material storage accommodating portion provided at a position within the movement range of the extrusion plate in the middle of the guide plate, and a pair of protective material storage accommodating portions installed between the accommodating portion and the protective material supply port, one of which is freely retractable from an opening formed in the guide plate. This is a protective material supplying device for wire rod coils, which consists of a protective forest pinching and supplying roller.

FIG. 2 shows an example in which a protective material supply device 5 is installed near the end of a wire rod conveyor 4 (which performs a cooling function) placed behind the wire winder 3.

A convergence device (convergence tab) 6 is provided below the terminal end of the conveyor 4 to receive the falling wire ring, and the supply device 5 also supplies coil end face protection material to the convergence tab 6. be.

FIG. 3 shows the details of the protective material supply device 5, in which a guide plate 7 is provided on the terminal end side of the conveyor 4, almost parallel to the conveyor, and the tip of the plate 7 is a guide for guiding the fall of the wire ring. It is attached to the protective material supply port 9 formed in the tube 8.

Further, on the rear end side of the guide plate 7, a protected forest extrusion plate 11 having an arc-shaped tip that moves forward and backward by an extrusion cylinder 10 is provided.
A cylindrical storage chamber 12 is provided in the middle of the guide plate 7 to store the protective material extruded one by one by the extrusion plate 11, and the storage chamber 12 intersects with the guide plate 7. It is connected to a protective material falling chute 12' extending in the direction shown in FIG.

Furthermore, an opening 14 is formed in the guide plate 7 between the storage chamber 12 and the protective material supply port 9, through which the lower roller 13 of a pair of protected forest pinching rollers appears. 13 is connected to a motor 16 via a speed reducer 15, and rotates to eject the protective material.

The focusing operation of the wire coil using the feeding device shown in FIGS. 2 and 3 will be explained in accordance with FIGS. 4A to 4E.

First, the protected forest 17 is sent to the storage room 12 from the falling chute 12'.
At the same time, the extrusion cylinder 10 is operated to push out a piece of protected forest 17A by the extrusion plate 11 to the position of the protected forest holding roller 13 on the guide plate 7 (FIG. 4A).

mouth).

Next, the motor 16 is operated to expose the pair of lower protected forest clamping rollers 13 that had been retracted under the guide plate 7 through the opening 14, and rotate together with the upper protected forest clamping roller 13 to move the protective material 17A into the guide cylinder. 8 inward from the supply port 9 (see Figure 4).

The protective material 17A that has been kicked out is set by fitting into the lower part of the focusing tab 6 that is waiting below the guide cylinder 8, and then the wire ring 18 begins to fall (FIG. 4-2).

The wire rod coils 19 dropped and accumulated around the collecting tab 6 have their lower end surfaces in contact with the protected forest 17A, and when the predetermined accumulation of wire rod rings 18 is completed, the same operation as that for supplying the protected forest 17A is performed next. As a result, the second protective material 17B is supplied, and this protective material 17B is attached to the bundled wire coil 19.
(Fig. 4 E).

After the wire rod coil 19 is bundled with the protective forests 17A and 17B in contact with both end faces in this way, the process moves to an appropriate inspection and weighing process, and the bundled coil is bound together with the protective material using a binding hoop material. do.

The wire rod coil after bundling is as shown in Fig. 5, and since both end faces of the coil are protected by the protective forest 17A and 17B, there are no contact scratches with the hoop material, scratches due to the coils rubbing against each other, and hook protrusions. Occurrence of scratches etc. is prevented.

In the present invention, as described above, the protective material for covering the lower end surface of the coil must be set on the focusing tab 6 before the first wire ring falls onto the focusing tab 6. In addition to the method of placing the focusing tab 6 in a predetermined position and then dropping the protective forest 17 onto the tab 6 as shown in FIGS. It is also possible to set the material and then move the tab 6 to a predetermined position.

Furthermore, the setting of the protected forest 17 is not limited to a method that relies entirely on an automatic feeding device, but depending on the case, it is also possible to combine an automatic feeding device and manual labor of working tools.

On the other hand, the protected forest 17 is shown as a donut-shaped circular plate having a hole in the center with a diameter sufficient to fit into the focusing tab 6, but in the present invention, the shape of the protected forest 17 is not limited to this. It can be in the shape of

For example, as shown in Figure 6A, a circular protective plate with radial and circumferential liquid parts alternately provided, a circular protective plate with the entire part formed into a rectangular shape as shown in the opening of Figure 6, or As shown in the figure, one that is large enough to cover not only the end face of the coil but also the side face can be considered.

As explained above, according to the convergence device of the present invention, it is possible to significantly reduce the occurrence of flaws during convergence of the wire, and it also leads to an improvement in the appearance of the coil packaging, which has a very large practical effect.

Furthermore, the process of the present invention can be easily incorporated into the online wire manufacturing process, which follows the wire rolling process, wire heat treatment process, and convergence process, without any problems, and greatly contributes to quality assurance.
