Abstract

PURPOSE:To easily correct the width camber of a banded product by forming a surface of curvature most suitable for correcting a width camber from a roll capable of varying the curvature of an external circumferential surface. CONSTITUTION:Axial compression is given to an elastic roll 2 by reciprocating an axial rod 1a. When this compression increases, the roll 2 contracts elastically and expands in its radial direction and when the compression decreases, an entirely contrary trend is developed structurally. Then, when a width camber is generated in a banded product, the compression of a compression device 1 is adjusted to set the curvature of the external circumferential surface of an elastic roll 2 to the optimum curvature to correct the width camber. Thus, the width camber of the banded product can be easily corrected.

[Prior art] When manufacturing thin metal sheets by roll rolling, the rolls may be insufficiently adjusted, or even if the adjustment is sufficient, the rolls may be deformed by the rolling blade, resulting in edge elongation, warping, meandering, etc. . In particular, when the thin plate is a composite metal strip made by rolling and pressure welding of dissimilar metals, the mechanical
Due to the difference in physical properties, curling, which is warping in the longitudinal direction, and camber, which is warping in the middle direction, as shown in FIG. 2, are likely to occur.

As shown in FIG. 2, if a width warpage occurs in the rolled strip product 3, rather than correcting it with the leveler, a drum-shaped roll having a peripheral curved surface opposite to the rlJ warp is used. It is easier to correct the r1 warp by letting it pass through and forcibly bending the width warp to the opposite side.

This lick and width warp correction device combines a drum-shaped mouth and a roll with a matching drum-shaped surface into a pair.
The belt-shaped product having rlr warpage is held between these rolls and bent in the opposite direction to correct it. (For example, Utility Model Application No. 6L - [Problem to be solved by the invention] Width warping that occurs during rolling varies depending on the material being rolled and the rolling conditions, and even if it is corrected by bending it to the opposite side. , the degree of bending must be changed depending on the elastic and plastic properties of the target material even if the degree of warp is the same.For this reason, in the conventional device, the curvature of both the drum-shaped roll and the drum-shaped roll is There is a problem in that it is necessary to prepare a large number of different items, and these must be replaced frequently.

[Means for Solving the Problems 1] The present invention uses an elastic roll instead of a conventional metal roll as a straightening roll. For example, a drum-shaped elastic roll is compressed in the axial direction. The curvature of the roll can be changed freely by applying compression force by a device and adjusting the compression force appropriately, and during straightening, the curvature of the roll can be adjusted according to the degree of warpage and rlj of the product to be straightened. It is possible to freely set the most appropriate curvature for the material, so that even if the products have different ri+curvatures, optimal correction can always be performed using one straightening roll.

(2) Compression devices 1 are placed opposite each other, and are constructed so that the shaft rods la, la can be moved forward and backward as indicated by arrows in the figure, using, for example, hydraulic pressure or a screw. Reference numeral 2 denotes a drum-shaped roll made of an elastic material and installed between the compression devices 1, 1. As shown in the figure, the elastic roll 2 is installed between the compression devices 1 and 1, and as mentioned above, when the shaft rods la and la are moved forward or backward, a compressive force is applied in the axial direction, and the compressive force is large. If this happens, the roll 2 will elastically contract in the axial direction and expand in the radial direction, reducing the radius of curvature of the outer circumferential surface of the roll 2. On the other hand, if the compressive force is reduced, it will expand in the axial direction and the radius of curvature of the outer circumferential surface will decrease. It is designed to be large.

Since the device according to the present invention is configured as described above, the compression force of the compression devices 1, 1 is adjusted in consideration of the degree of width warping of the band-shaped product 3 to be straightened, so that the outer peripheral surface of the elastic roll 2 is adjusted. The curvature is set to the optimum curvature for correcting the width warpage, and the product 3 is passed through the roll 2 in this state. Next, when trying to straighten products with different width warpages, the best straightening work can be performed continuously by simply adjusting the compression force without replacing the rolls one by one as in the conventional example.
