Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a tape guiding method for manufacturing cladding materials. In particular, the present invention relates to a tape guide method for manufacturing a cladding material that can always guide the base metal and cladding tape in a constant position.

Conventionally, when manufacturing clad strips continuously by overlapping base metal and clad tape, the base metal guide and the clad tape guide are fixed separately, so it is difficult to keep the relative position constant and supply the clad strip. It was difficult. This is also
There are also aspects in which it is not possible to sufficiently follow changes in the tension of the pre-treatment line and the rolling conditions of the clad rolling mill.
There were drawbacks such as the difficulty of always supplying the cladding tape in a constant position relative to the base metal.

For guides for clad tape, please see
For example, a method of guiding with grooved rolls has been proposed, but this method has disadvantages such as rolling fluctuations causing the tape to swing from side to side, causing damage to the tape edges.

Furthermore, a method has been proposed in which the position of the cladding tape is quantitatively checked after rolling, and the position of the cladding tape is tracked and controlled to match the base metal position through feedback, but this also involves delays in control and poor positioning accuracy. I can't expect much. Also,
Fluctuations in the mating material before rolling become a factor that impairs rolling conditions, making positioning increasingly difficult.

From this point of view, it is necessary to guide the base metal and the clad tape so that their mutual positions are always constant before rolling. That is, it is necessary for both to be guided at a constant position regardless of rolling variations, and to be guided by a guide with a long contact length that is not affected by pretreatment.

As a result of various studies to eliminate these conventional drawbacks, the present inventors have developed a tape guide method that can always guide the base metal and clad tape in a constant position in order to manufacture clad materials. Achieved an invention.

That is, the present invention provides a tape guide method for manufacturing a cladding material that determines and guides the running position of a base metal and a cladding tape clad thereon, in which the base metal is guided by a plurality of slide rollers, and the cladding tape is guided by a plurality of slide rollers. This is a tape guide method for manufacturing a cladding material, characterized in that the cladding tape is guided integrally with the base metal using a groove provided in the guide for the cladding tape or a groove cut into the base metal.

Hereinafter, the present invention will be explained together with a conventional method with reference to the drawings.

FIG. 1 is a schematic explanatory diagram showing an example of a conventional clad manufacturing apparatus, in which a clad tape 1 made of a metal such as copper and a base metal 2 made of a metal such as iron are fed out from respective feed reels 11 and 12. After being pretreated by the pretreatment device 10, the material is rolled into a cladding by the clad rolling rolls 3 and 4, and then wound onto the take-up reel 7. In addition,
5 and 6 are rolled back-up rolls.

Conventionally, as shown in the figure, the positioning of the clad tape and base metal is regulated by guide rolls 8 and 9, but as mentioned above, the positional relationship between the two is affected by fluctuations during rolling, fluctuations in pretreatment, etc. It was difficult to maintain a constant position due to the impact.

FIG. 2 is a cross-sectional view showing one embodiment of the guide used in the present invention, and FIG. 3 is a longitudinal cross-sectional view thereof.

The base metal 2 from a delivery roller and a pretreatment device (both not shown) is guided by a plurality of slide rollers 14 and a guide plate 15, and is sent to the clad rolling rolls 3 and 4. A clad tape 1 (not shown) is guided while regulating its position by a groove 16 provided in a clad tape guide 13, and guided to clad rolling rolls 3 and 4 integrally with the base metal 2. .

With this configuration, the traveling position of the base metal is regulated by the plurality of slide rolls, and the traveling position of the clad tape is regulated by the groove provided in the clad tape guide. The clad material can be guided to the rolling section in a constant positional relationship, and clad material of desired size and shape can be continuously obtained.

In addition, in order to prevent the base metal and the clad tape from coming into contact with each other during guidance and affecting each other, a second
As shown in the figure, the entrance of the tape guide is wide.
It is preferable to have a tapered shape so that the outlet part becomes narrow so that the clad tape 1 does not come into contact with the base metal 2 when it enters the clad tape guide 13. Further, the groove at the entrance end of the clad tape guide 13 is curved as shown in the figure, and it is preferable that the clad tape is guided along this curved portion.

FIG. 4 is a longitudinal sectional view showing another embodiment of the guide used in the present invention, in which the guide groove of the clad tape 1 is not provided in the clad tape guide but is previously provided in the base metal. That is, the guide groove 17 of the clad tape is formed on the surface of the base metal 2.
are provided in advance, and the base metal 2 is guided by the slide roll 14, and the clad tape 1 is inserted into the groove 17 provided in the base metal 2.
We will guide you while regulating it. In this case as well, it is desirable to make the entrance part wide so that the clad tape can be accommodated in the groove 17 of the base metal 2 as close to the exit part as possible.

Since the present invention is as described above, the base metal and the cladding tape are guided while always keeping the positional relationship constant, without being affected by fluctuations during rolling or material fluctuations during pretreatment, and the desired cladding tape is guided. Articles can be obtained.

Further, according to the present invention, the guide itself has a simple structure and is easy to attach and remove, so a desired guide can be easily assembled depending on the size of the base metal or clad tape.
