Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for guiding a rolled material for easily changing the size of a roller guide accompanying a change in rolling size.

[0002]

In Japanese Utility Model Publication No. 50-10440, a guide provided with a cylinder drive type guide fixing device and a guide shift device is driven by a cylinder so that the position of the guide can be adjusted to a required caliber in a short time. An apparatus is disclosed.

Japanese Utility Model Laid-Open No. 54-6331 discloses a technology in which a roller guide provided with a guide moving table engaged with a screw shaft so as to be movable in the axial direction of a rolling roll can be adjusted in position according to a desired caliber. Is disclosed.

[0004]

According to the above-mentioned prior art, although it is possible to easily change the caliber of the roller guide due to the change of the rolling size, the guide of the guide is aligned after the guide is aligned with the required caliber. When it is necessary to change the interval, there is a problem that the interval of the guide cannot be resized in a short time. Also, for example, as in flat steel rolling, 1
When it is necessary to change the width dimension of the rolled material to be rolled by the book rolling rolls from an extremely narrow width to a wide width in units of several hundreds of mm, these prior art techniques require a large adjustment of the interval between the roller guides. There is a problem that can not be done.

The object of the present invention is to efficiently move the rolling size change required for high-mix low-volume production, and the time for moving the roller guide along the path line and the guide roller according to the path line. It is to shorten the time to adjust the interval. Another object of the present invention is to enable a large gap adjustment of roller guides from a narrow width to a wide width, which is required when a rolling size is changed, such as flat steel rolling.

[0006]

The method for guiding a rolled material according to the present invention uses a set of two roller holders, and a guide roller is rotatably supported by each of the roller holders. .. Each roller holder is independently movable between one end side and the other end side in the axial direction of the rolling roll, and the distance between the roller guides can be adjusted from a narrow width to a wide width. .. The pass line of the rolled material to be rolled by the rolling roll, and the distance between the guide rollers required in this pass line, by independently moving the roller holder to a required position in the axial direction of the rolling roll, The rolling line is guided by adjusting the pass line and the guide roller interval of the guide rollers provided in the pair of two roller holders to change the rolling size.

[0007]

Operation: To change the rolling size, adjust the position of each roller holder at the same interval from the path line so that one roller holder and the other roller holder are centered around the required path line. To do. When the rolled material is displaced from the pass line to one of the positions, the respective roller holders are moved in parallel to the direction for correcting the displacement. Further, when it is desired to tightly bind and guide one of the guide surfaces of the rolled material with the roller guide, one of the roller holders may be moved in a direction approaching the pass line.

As described above, by individually moving each pair of two roller holders, it is possible to freely change the pass line according to the change in rolling size and adjust the interval between the guide rollers with respect to the pass line. If necessary, the roller holders can be arranged asymmetrically with respect to the pass line.

[0009]

Embodiments of the present invention will be described with reference to the drawings.
Two in the guide box 1 arranged on the rolling roll R 1
A guide roller 4 is rotatably supported by a pair of roller holders 2 and 3 via roller pins 2a and 3a, respectively.
The roller holders 2 and 3 are slidably fitted to slide shafts 5 and 5 provided on the guide box 1,
Further, the feed screws 6 and 7 rotatably supported by the guide box are screwed together at the connecting portions 2b and 3b in which the screw nuts of the roller holder are screwed. Are connected to the servomotors 8 and 8 each equipped with a pulse transmitter provided in the.

The servomotors 8 and 8 are connected to a controller 9 having a positioning function, and the amount of rotation can be controlled in accordance with a command from the controller, so that the amount of rotation of the servomotor is used as a parameter. The roller holders driven by the servomotors via the feed screws 6 and 7 can be individually positioned.

In order to align the roller holders 2 and 3 with a required path line at a required interval, the control device is provided with three position command digital switches 9a, 9b and 9c, one of which is provided. The digital switch 9a is for the pass line command, and the remaining two are the roller holder 2,
Digital switch 9 for commanding the distance from the 3rd pass line
b and 9c.

For example, a pair of two roller holders 2 and 3
As shown in FIG. 4, when the rolling size is changed, the pass line is 700 mm from the one end side of the rolling roll R and the distance between the guide rollers 4 is 200 mm.
When the path line is 400 mm and the distance between the guide rollers is changed to 300 mm as shown in (4), the path switch command digital switch 9a is set to 400, and the roller holder 2 position command digital switch 9b and the position of the roller holder 3 are set. Input 150 to each of the command digital switches 9c, press the movement start button 9d of the control device 9,
The servo motor 8 is driven to move it to a desired position.

For example, when it is desired to set the roller holder 2 to be narrower than the path line by 2 mm, 148 is input to the digital switch 9b for commanding the position of the roller holder 2 and the movement start button of the control device 9 causes the servo motor 8 to move.
Can be driven, and the positions of the roller holders 2 and 3 can be arbitrarily changed.

The roller holders 2 and 3 which have completed the position adjustment associated with the change in the rolling size are provided with the hammer bolt 1 on the roller holder.
It is fixed to the guide box 1 by hydraulic clamps 11 and 11 provided via 0 and 10.

Further, in this embodiment, a horizontal roller 12 (FIG. 2) is provided to assist and guide the rolled material to the guide roller, and the control device 9 and the servomotors 8 and 8 are connected to the electric wires 13 and 13.
Is connected with.

In the case of rolling a rod or the like, when it is not possible to share the hole shape of the guide roller with the plurality of hole shapes provided in the rolling roll R, the guide box 1 has four holes.
If two sets of roller holders are provided and position adjustment is possible,
It is possible to support a plurality of hole types.

In the above example, a servomotor is used as a means for independently moving each pair of two roller holders. However, the invention is not limited to this example, a hydraulic motor may be used, and a feed screw is used instead. A hydraulic cylinder may be used.

[0018]

According to the present invention, by individually moving each pair of two roller holders, it is possible to freely change the pass line according to the change in rolling size and adjust the distance between the roller guides relative to the pass line. Since it is possible to significantly adjust the interval between the roller guides, it is possible to change the rolling size of the flat steel rolling, and it is possible to change the size of the roller guides in accordance with the rolling size change in a short time.
