The present invention relates to improvements in a correction method and device for correcting camber.

るキャンバを生じ易い。[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.
圧延条に上記のような形状不良か生じた場合には、一連

する作業を行なうのが通常である。When a rolled strip has a shape defect as described above, it is normal to correct the defect by passing it through a leveler consisting of a series of correction rollers.

容易である。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.

してやらねばならないという問題かある。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.
また、これらのロールは金属製であるから、無理な曲げ

いう問題もあった。Furthermore, since these rolls are made of metal, there is also the problem that they tend to scratch the surface of the strip-shaped product when applying excessive bending.

To provide a novel method and device for correcting rlJ warpage of a strip-shaped product, which does not require the preparation of a large number of rolls for correction, and which eliminates the risk of inadvertently damaging the product.

うにするものである。[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.
[実施例1 以下に、本発明について実施例図面を参照し説明する。[Example 1 The present invention will be described below with reference to the drawings.
第1図は、本発明に係る矯正装置の具体的構成を示す説

くなるように構成されている。(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.

.. 4 is a presser roll for applying the above-mentioned forced reverse direction, and 5, 5 is a spring that applies a pressing force to the presser rolls 4, 4.

続的に最良となる矯正作業を施すことができる。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.
なお、ロール2の材質については、必要な弾性変形能と
金属条に逆反りを与え得るなl−1の機械的強度、それ

などが適当である。Regarding the material of the roll 2, it is necessary to consider the necessary elastic deformability, the mechanical strength of 1-1 that can cause reverse warpage to the metal strip, and the abrasion resistance. For example, urethane rubber is suitable. be.

なものとして、適宜必要な構成を選択すれはよい。Such an elastic material may be used in any suitable configuration, such as a solid body, a hollow body, or a hollow body filled with a liquid such as water.
さらに、上記の具体例は圧縮装置によりロール= 6−

る矯正方法を実施するにはそれのみに限定はされない。Furthermore, although the above specific example has a configuration in which the curvature of the outer circumferential surface of the roll 6- is changed by the compression device, the correction method according to the present invention is not limited to this.

を用いるよりも有効化できる場合がある。That is, the elastic roll may be configured to have both ends in a rigid state and apply internal pressure to the inside of the roll, and the internal pressure may be used to adjust the expansion of the outer circumferential surface to change the surface of curvature. According to this, by selecting the material of the internal pressure imparting substance, it may be more effective than using the compression device described above.

A compressive force is applied to this to cause a drum-shaped deformation on the urethane rubber roll, and the Fe-42%/Ni alloy strip with a thickness of 0.1 mm, medium 50 mm, and width warpage of about 1 nm is straightened. When we performed this, we were able to obtain very good correction results.

It has been demonstrated that good straightening can be achieved continuously with one roll.

1- is installed, and the curvature of the drum-shaped roll 4- is configured to be changeable according to the change in the curvature of the drum-shaped roll 2, thereby making it possible to match both curvature surfaces. The pressing force between the roll 2 and the roll 4- is provided by the springs 5, 5 as in FIG. There is no problem in using air pressure or mechanical pressure such as a screw.
