DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a side guide zeroing device for a rolling mill.

[0002]

2. Description of the Related Art A rolled material such as a hot slab is rolled to a predetermined width,
In order to obtain a product having a large thickness, it is usually necessary to perform a rough rolling step before performing a finish rolling step.

[0003] The conventional equipment for performing the above-mentioned rough rolling step is, as schematically shown in FIG. 4, in which a rolling device 3 comprising an edging mill 1 and a horizontal mill 2 is arranged in multiple stages along a pass line L, and A transport table 5 in which a large number of transport rolls 4 are arranged at positions before and after each rolling device 3.
Further, on the upper side of the transport table 5, side guides 6 shaped to avoid the respective transport rolls 4 are disposed so as to face left and right with the pass line L interposed therebetween. Is provided with a cylinder 7 as an interval adjusting device on the back surface thereof, and guides the rolled material 8 such as a slab conveyed on the conveying table 5 to the rolling device 3 while regulating the position by left and right side guides 6. 1 and the thickness reduction by the horizontal mill 2 are repeatedly processed to a predetermined size. Reference numeral 9 denotes left and right table frames constituting the transfer table 5, and 10 denotes a bearing of the transfer roll 4.

[0004]

However, the rolling mill 3
The left and right side guides 6 arranged at the front and rear positions need to be accurately set in accordance with the plate width because errors due to sensor malfunctions and the like are accumulated. Although the zero to be checked (correctly resetting) is performed, the conventional method of zero adjustment is to insert a measuring plate between the left and right side guides 6 or to operate the space between the left and right side guides 6. Since the measurement is performed by a worker, the measurement accuracy tends to be inaccurate even though the measurement work is difficult.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a side guide zero-adjusting device for a rolling plant, which can easily and accurately perform zero adjustment of a side guide.

[0006]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, according to the present invention, left and right side guides are provided above a transport table in which transport rolls arranged in the direction of a pass line are supported between left and right table frames. The support beam is erected between the left and right table frames of the transfer table in the rolling equipment that is arranged close to and releasable so as not to interfere with the transfer rolls, and based on the center of the pass line on the support beam. A zero-adjustment seat for being sandwiched between the right and left side guides by the proximity movement of the left and right side guides is fixed at a predetermined width interval.

[0007]

When performing the zero adjustment of the side guides, the left and right side guides are moved in the approaching direction to abut against the zero adjustment seat so that the left and right side guides sandwich the zero adjustment seat. Since the width of the zero-tone seat is set based on the center of the pass line, the zero-tone is accurately performed.

[0008]

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

FIGS. 1 to 3 show an embodiment of the present invention. Similar to the rolling equipment shown in FIG. A transport table 5 supporting the transport rolls 4 arranged in the direction of the pass line L is installed between the table frames 9 of
In addition, left and right side guides 6 are arranged on the upper side of the transfer table 5 so as to be able to approach and separate from each other, so that the left and right side guides 6 can regulate the position of the rolled material 8 transferred on the transfer table 5 in the left and right direction. The left and right table frames 9 constituting the transfer table 5
Between the transport rolls 4 arranged in the direction of the pass line L, the support beam 11 is bridged, and the side guide zero adjustment for the side guide zero adjustment is performed at the position A at the right and left intervals from the center C of the pass line on the support beam 11. The seat 12 is protruded at a height lower than the upper surface level of the transport roll 4, and
Are moved in directions approaching each other, the lower end portions 6a of the side guides 6 interposed between the transport rolls 4 can be brought into contact with the zero adjustment seats 12, respectively. The dimension (= A × 2) between the right and left zero adjustment seats 12 is set to be the minimum sheet width of the rolled material 8 or smaller than the same.

1 to 3, the same parts as those in FIG. 4 are denoted by the same reference numerals.

When the rolling material 8 is sequentially rolled by each rolling device 3, when the interval between the left and right side guides 6 arranged on the transfer table 5 is set in accordance with the width of the rolling material 8, the cylinder 7 is used. The left and right side guides 6 are temporarily moved in the approaching direction by the extending operation of the side guides 6, and the lower end portions 6 a of the side guides 6 are brought into contact with the respective zero-adjustment seats 12 on the support beam 11 as shown by the two-dot chain line in FIG. The right and left side guides 6 are sandwiched between the left and right side guides 6 so as to be in contact with each other. At this time, the above-mentioned zero adjustment seat 12 is distributed to the position A at the right and left equal intervals from the center C of the pass line, and the side guides 6 are respectively set to the zero adjustment seat 12.
Since the backlash of the drive system has disappeared at the time of contact, the zero adjustment has been performed accurately. Therefore, the interval can be set accurately by expanding the left and right side guides 6 to a predetermined position after the zero adjustment.

In the above, the zero adjustment of the side guide 6 is
This can be performed automatically by simply sandwiching the zero-adjustment seat 12 with the side guide 6, so that workability and efficiency can be improved, and reliable operation can be performed in a short time even during operation. Since it is possible, it is advantageous also in terms of productivity.

In the above-described embodiment, a case has been described in which a pair of the zero adjustment seats 12 are provided with the pass line L interposed therebetween. However, a plurality of pairs may be provided in order to cope with the generation of a couple when the side guide 6 abuts. In addition, although the embodiment has shown the case where the zero adjustment seats 12 are respectively protruded from the pass line center C at the width interval positions, an integral block-shaped zero adjustment seat having a predetermined width may be used. Further, in the embodiment, the case where the cylinder 7 is used as the interval adjusting device of the side guide 6 is shown. However, a rack and pinion system, a screw rod system, or the like may be used. Of course, various changes can be made without departing from the scope.

[0014]

As described above, according to the side guide zeroing device of the rolling equipment of the present invention, the support beam is bridged between the left and right table frames, and the zero adjustment device having a predetermined width is set on the support beam. Since the seat is fixed, it is possible to automatically and accurately perform zero adjustment just by moving the left and right side guides once to sandwich the zero adjustment seat, thereby shortening the time required for zero adjustment work , The workability and efficiency can be improved, and an excellent effect of contributing to an improvement in productivity can be exhibited.
