Description

Detailed Description of the Invention 3. Detailed Description of the Invention C Industrial Application Field The present invention relates to a leveler capable of controlling the shape of a strip in the width direction.

[Prior Art] Conventional levelers are used to ensure straightness in the longitudinal direction of the strip, and this is done by passing the strip in a zigzag pattern between a number of rolls of the required length. .

However, in recent years, as shown in FIG. 8, single-tapered crown rolls 7 having a tapered surface at one end of the roll are arranged alternately on the upper and lower sides of the strip along the longitudinal direction of the strip. It has been proposed to control the shape of both ends of the strip by arranging them so that they alternately contact both ends of the strip.

[Problems to be solved by the invention] However, the above-mentioned conventional single-tapered crown roll,
The purpose of this method is to control the shape of both ends of the strip along the longitudinal direction of the strip, and it is not possible to actively control the shape of the strip in the width direction.

SUMMARY OF THE INVENTION An object of the present invention is to provide a leveler that can effectively control the shape of the strip according to changes in conditions such as width, thickness, and shape of the strip, and can perform processing in the width direction of the strip. .

(Means for Solving the Problems) The present invention provides a leveler that corrects the flatness of a plate by passing a strip between upper and lower rolls and imparting a plastic ridge with a predetermined radius of curvature. A roll body is constructed by providing a plurality of drum-shaped rolls at a required interval in the width direction of the strip, and the drum-shaped rolls provided on the roll body are adjacent to each other in the longitudinal direction of the strip, and the opposite side of the strip is The drum-shaped rolls are arranged so as to be located between the drum-shaped rolls of the roll body arranged on the side, and the positions of the drum-shaped rolls are individually adjustable in the board width direction while maintaining the above state, The roll body is provided with a position adjustment device that moves the roll body in the width direction of the strip according to the widthwise position of the strip, and the upper and lower roll bodies are arranged so as to overlap at the same position. This is a leveler that does this.

[Function] Therefore, in the present invention, the distance between the drum-shaped rolls is changed depending on the thickness of the strip, and the roll body is moved in the width direction of the strip depending on the shape and widthwise position of the strip. Leveling in the width direction is possible.

[Example] Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a diagram illustrating the shape of a roll body in an embodiment of the present invention. A drum-shaped roll 2 is inserted into the small diameter shaft 1 so that its position can be adjusted in the board width direction. The drum-shaped roll 2
Locking devices 3 for fixing the position of the drum-shaped roll 2 are provided on the left and right sides of the drum-shaped roll 2. At one end or both ends of the small diameter shaft 1, there is provided a position adjustment device 4 such as a cylinder that moves back and forth in the width direction of the strip 5 to follow the shape of the strip 5. Further, all of the small diameter shafts 1 are provided with a distance adjusting device (not shown) for changing the distance between the small diameter shafts 1 in the longitudinal direction of the strip.

When using the leveler of the present invention, as shown in FIG. 1, the strip 5 whose shape is to be controlled is Depending on the width and thickness, the number and spacing L of the drum-shaped rolls 2 are determined as shown in FIGS. 3 to 5.

The drum-shaped rolls 2 are moved in the board width direction by a required number, and the drum-shaped rolls 2 that are adjacent to each other are placed at equal intervals and fixed by a locking device 3. In the small diameter shaft 1 of the next stage, the strip 5 is shown as a solid line and a broken line in FIG.
In order to reverse the bending direction, the drum-shaped roll 2 is fixed at an intermediate position between the drum-shaped rolls 2 of the small diameter shaft 1 of the previous stage. Thereafter, the drum-shaped roll 2 of the small-diameter shaft 1 is successively fixed so as to be located at an intermediate position with respect to the drum-shaped roll 2 of the roll in the previous stage.

A position adjusting device 4 provided at one end or both ends of the small diameter shaft 1 according to changes in the width dimension and shape of the strip 5.
The roll body can also be moved in the width direction of the plate.

Further, in order to enhance the effect of controlling the shape of the strip 5 in the width direction, it is possible to move the distance L2 between the rolls in the longitudinal direction of the strip 5 using a spacing adjustment device (not shown).゛Figure 6 shows the small diameter shaft l above the strip 5.
FIG. 3 is a diagram illustrating a case where the distance between the small diameter axis I on the lower side of the strip 5 and the longitudinal direction of the strip 5 is set to 0, and the strips 5 and 5 are overlapped at the same position. In this case, the drum-shaped roll 2 of the small-diameter shaft 1 is fixed at an intermediate position with respect to the drum-shaped roll 2 of the small-diameter shaft 1 that is in contact with the adjacent small-diameter shaft 1.

Further, FIG. 7 is a diagram illustrating a case where the apparatus shown in FIG. 3 is combined with the tray 1 and the roll 6. When the thickness of the strip 5 is relatively thin, a straight roll 6 is combined with the small diameter shaft 1 having the drum-shaped roll 2 to prevent wrinkles from forming in the thin strip 5.

It should be noted that the present invention is not limited to the above-mentioned embodiments,
It is possible to use an integrated drum-shaped roll fixed to a small diameter shaft, and it is also possible to replace the position adjustment device, locking device, etc. with a separately manufactured device having the same type of function. It goes without saying that various changes may be made without departing from the gist of the invention.

[Effects of the Invention] As described above, according to the apparatus of the present invention, by leveling the strip in the width direction, it is possible to change the strip width and improve the material quality, and it is also possible to change the strip width and improve the material quality. Various excellent effects can be achieved, such as being compatible with strips of different thickness and being usable even with strips whose shape is not bilaterally symmetrical.
