Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to an outlet guide position control device capable of adjusting a twist angle of a roller guide and adjusting a guide roller interval.

(Prior Art) Conventionally, as a device for adjusting the twisting angle of the exit guide, there is one described in Japanese Utility Model Publication No. 57-29931 proposed by the present applicant. In this conventional example, a worm formed in a roller holder rotatably held in a guide box is engaged with a pinion provided in the guide box, and the pinion is rotated to adjust the twist angle of the roller holder. At the same time, a pair of guide rollers are rotatably supported on the roller holder by eccentric shafts, and the worms formed on the eccentric shafts are engaged with the shaft-integrated pinions by the reverse screws to rotate the pinions. The distance between the rollers can be adjusted.

(Problems to be solved by the invention) In the conventional example, in order to guide the roller holder by twisting 90 degrees from the rolling roll equipped with the roller guide device for the rolled material to the next rolling roll, the roller holder has a predetermined twisting angle. The rolling material is pre-twisted from the rolling roll by the friction guide, guided to the guide roller and bound, and guided to the rolling roll of the next stage. Therefore, when the rolled material is pre-twisted, it is easily scratched because it causes friction with the friction guide, and when the friction guide is worn, the pre-twisted angle is insufficient and the rolled material collides with the guide roller to cause flaws. There was a problem to turn on.

The purpose of this invention is to eliminate the problem of the rolling material colliding with the guide roller and causing a flaw when the friction guide is worn and the pre-twist angle is insufficient.
The purpose is to easily and accurately adjust the interval between the guide rollers.

(Means for Solving the Problem) In the position control device for an outlet guide according to the present invention, a roller holder is rotatably inserted and held in a guide box. A worm wheel portion is formed in this roller holder, and a drive device that applies a rotational force to the worm meshing with the worm wheel portion is provided. A rotation amount detector that measures the rotation amount of this drive device is provided. It is provided in the guide box, and the drive machine can be operated remotely.

A pair of guide rollers are rotatably supported on the roller holder by an eccentric shaft, and worms formed on the eccentric shaft are engaged with shaft-integrated pinions by mutually reverse screws to give a rotational force to the shaft. A drive machine is provided in the roller holder, and a rotation amount detector for measuring the rotation amount of the drive machine is provided in the roller holder. The drive machine can be operated remotely.

(Operation) When the pre-twist angle is insufficient, the roller holder can be rotated by operating the driving machine to set a desired twist angle. The interval between the guide rollers is automatically adjusted by operating the roller holder driving machine. The rotation amount detector is used to detect and control the position of the roller holder and the position of the guide roller to set the twist angle and adjust the guide roller interval.

(Embodiment) An embodiment of the present invention will be described with reference to the drawings. In FIGS. 1 and 2, a guide box 1 is fixed to a rest bar (not shown) via a base 2, and inside the guide box, from the rear end of the rolling mill (left side in the figure) to the guide box. The twist guide 3a is inserted up to the intermediate portion of the above, and the twist guide 3b is inserted from this intermediate portion to the tip on the guide roller side described later. Further, the roller holder 4 is rotatably inserted from the tip of the guide box 1 toward the intermediate portion, and this insertion portion is held by the retaining nut 5 in the guide box. Roller holder 4
As shown in FIGS. 1 and 3, the worm wheel portion 6 is formed on the base plate. The worm wheel portion 6 has a pinion shaft 7 that is axially supported by the bearing of the guide box 1.
The pinion 7a formed on the meshes with each other. At one end of the pinion shaft 7, a worm 7b (Fig. 3)
The worm has a guide box 1
The pinion 9 attached to the tip of the shaft of the drive unit 8 fixed to the gear meshes with it. A rotation detector 10 for measuring the rotation amount of the pinion 9 is provided adjacent to the driving machine 8.

Therefore, due to the rotation of the pinion 9 driven by the driving machine 8, the rotational force is transmitted to the roller holder 4 through the worm wheel portion 6 and rotated, whereby the roller holder shown in FIG. 3 can be set to a predetermined twist angle θ.

A pair of upper and lower guide rollers 11 and 12 are rotatably supported by eccentric shafts 13 and 13 at the tip of the roller holder 4. At the end of the eccentric shaft 13, there is a pinion 1 with a reverse screw relationship with each other.
4,15 are installed. Each pinion 14, 15 has a worm mounted on a shaft 17 rotatably supported by a bearing 16.
18,19 are in mesh.

A worm 20 is provided at the end of the shaft 16. The worm 20 meshes with a pinion 22 attached to the tip of the shaft of a driving machine 21 fixed to the roller holder 4. Driven a rotation amount detector 23 for measuring the rotation amount of the pinion 22.
It is located adjacent to 21.

Therefore, due to the rotation of the pinion 22, its rotational force is transmitted to the shaft 17 through the worm 20, the pinions 14 and 15 rotate via the worms 18 and 19, and the guide rollers 11 and 12 move the eccentric shafts 13 and 13. Rotating about the center, the roller spacing is adjusted.

Next, the usage will be described.

The twisting angle θ of the roller holder 4 is set in advance so that the twisting angle required to guide the rolled material from the former rolling mill to the next rolling mill by 90 degrees is set to the twisting angle of the rolled material. When the excess or deficiency occurs, the twist angle of the roller holder is adjusted to a desired angle.

In this adjusting operation, the driving force of the driving machine 8 is applied to the worm wheel portion 6 to rotate the roller holder 4. The measurement data from the rotation amount detector 10 is calculated by a calculation device to detect the position of the roller holder 4 and control its position.

Further, the drive machine 21 is operated between the guide rollers 11 and 12, and the pinion 22 is rotated by a predetermined number of rotations to adjust the roller interval. In this adjustment, the rotation amount detector 23 is used to control the position. The drive machines 8 and 21 are operated by remote control.

(Effect of the Invention) According to the present invention, since the twisting angle of the roller holder and the interval between the guide rollers are adjusted by using the driving machine and the rotation amount indicator, the work of setting the twisting angle and adjusting the roller interval are performed. The position control can be performed automatically without any manual operation, and the position control can be performed quickly and easily and accurately by remote control.
