The present invention relates to a guide device for adjusting the transfer state of the hot rolled sheet manufactured in the form of a strip (STRIP) through the hot rolling and rolling process before coiling the coil, more specifically, the coiled rolled sheet subjected to the hot rolling and rolling process Winding hot-rolled sheet guide which minimizes friction by maintaining the contact between the guide device and the rolled plate to guide the transfer of hot-rolled sheet with a suitable force before winding it with Relates to a device.

In general, in the hot rolling process, a slab heated in a heating furnace is rolled thinner through a ROUGHING MILL to be manufactured in a bar shape, and then a plurality of driving units installed on a transfer tail. Surface treatment is performed through a cutter for cutting the front end and the end of the rolling bar by using a roll and a scale remover (FSB, FISHING SCALE BRAKER) generated on the surface of the rolling bar. It is produced as a plate product, and then to produce the coil product by winding the hot rolled sheet to facilitate transport.

However, in order to perform such a series of hot rolling processes precisely, in order to perform various cutting and surface treatment of the rolling bar and hot rolled plate during transfer, they must always be constantly transferred along the center line of the transfer line. It is important to adjust the centerline of a hot rolled sheet with a thin plate shape.

Such a conventional hot rolled sheet guide device is illustrated in FIGS. 1 and 2.

That is, as illustrated in FIGS. 1 and 2, guides the hot rolled plate 100 to be transferred inward along the transfer table 110 to both sides of the transfer table 120 on which the transfer roller 110 is installed. The guide plate 130 is installed, in which case the guide plate 130 is installed to be adjusted in accordance with the width of the hot rolled plate 100 by connecting the cylinder 140 to the rear.

Therefore, in the conventional hot rolled sheet guide device as described above, when the hot rolled sheet 100, which has undergone the whole process of the hot rolled line, enters the transfer table 110 provided with the winding machine at its end, the guide plate 130 is appropriate. After adjusting to the position is to guide the hot rolled sheet 100 to be transported inward to match the center of the winder.

However, in the conventional hot rolled sheet guide device as described above, the guide plate 130 and the hot rolled sheet 100 are excessive by guiding the hot rolled sheet 100 to be conveyed by narrowing or spreading the plate-shaped guide plate 130. It is easy to be guided under the force, and in this case, the edge portion of the hot rolled sheet 100, which is a thin iron plate, and the guide plate 130 are in close contact with each other, so that the edge portion of the hot rolled plate 100 or the contact surface of the guide plate 130 is provided. In the chip (CHIP) is generated, such a chip is to be damaged between the surface of the hot rolled sheet 100 or the coil wound during the next hot rolled sheet winding operation between the various equipment such as rolls.

On the other hand, the conventional hot rolled sheet guide device for solving the problems occurring in the conventional hot rolled sheet guide device is schematically shown in FIG.

That is, as shown in Figure 3, another conventional guide device is to guide and install the guide rolls 200 to both sides of the transfer table 110 instead of the guide plate 130, such a conventional hot rolled plate The guide device may be guided while stably reducing friction as the guide rolls 200 which operate in rotation as compared to the conventional guide device.

However, in another conventional hot rolled sheet guide device, a contact portion of the guide roll 200 in which the corner portion of the hot rolled sheet 100 contacts is limited so that grooves due to the hot rolled sheet are easily generated in the guide roll 200. In this case, it becomes impossible to precisely guide the hot-rolled sheet 100, as well as the maintenance and maintenance costs are increased by the replacement of the guide roll 200.

The present invention has been made in order to improve the various problems as described above, the purpose is to guide the hot rolled plate in the transfer before the winding operation of the hot rolled plate undergoes a hot rolling process to the center of the transfer line, as well as a unique guide As the device is guided while rotating in the conveying direction of the transfer hot rolled sheet, the generation of chips due to over-contact between the guide device and the hot rolled sheet is minimized, and the winding hot rolled to prevent surface damage of the winder and the hot rolled sheet due to the chip. It is to provide plate guide device.

Referring to the operation and effects of the present invention made in the above configuration in more detail as follows.

As shown in FIGS. 4 to 8, an important feature of the guide device 1 of the present invention will be described in detail below, but the hot rolled plate 10 enters the guide device 1 by being transferred on the transfer table 22. When the width of the hot rolled sheet 10 is appropriately adjusted according to the width of the hot rolled sheet 10, the edge of the hot rolled sheet 10 by guiding the rotation method, friction between the hot rolled sheet 10 and the guide block 72 in direct contact therewith This is minimized, but explained in more detail as follows.

First, as shown in FIGS. 4 and 5, when the screw bar 38 connected between the bearings 36 installed on both lower sides of the transfer table 22 is rotated by the driving motor 34 installed on one side. , The guide block 40 is fastened to each other by the right screw portion and the left screw is narrowed or widened with each other to match the width of the hot rolled plate 10 to enter the guide device (1), such as of the drive motor 34 Although not shown in the drawing, the driving is controlled by receiving a signal from a sensor that senses the width of the hot rolled sheet 10 before the guide device 1 enters.                     

At this time, the guide block 40 is inserted and fixed inside the moving block 32 having a U-shaped cross section extending along a predetermined length along the transfer table 22, such a moving block 32 and a screw Bars 38 are approximately two pairs installed.

Accordingly, the guide block 40 moving when the driving motor 34 is driven is to narrow or widen the elongated moving block 32 integrally, and as shown in FIG. 6, front and rear of the moving block 32. After the fixing shaft 52 of the connecting means 50 is fixed by a screw method, the cylindrical guide block 56 is fixed to the outside of the upper head 54 via a bearing.

On the other hand, as shown in Figure 5, two suitable feed rolls 20 on which the guide device 1 is installed are disassembled and the guide block which is screwed to the housing 74 of the guide portion 70 on both sides thereof ( 72 are fitted opposite each other.

Accordingly, the guide block 56 of the connecting means 50 installed on the moving block 32 is provided in the guide groove 76 integrally formed on the outer circumferential surface of the housing 74 in which the feed roll 20 is inserted. Is inserted.

That is, when the moving block 320 is narrowed by the operation of the drive motor 34, the housing 74 and the guide block 72 is integrally moved in the transverse direction along the feed roll 20, and at the same time It also supports the rotation of the housing 74 and the guide block 72 in front of it.

Next, as shown in FIGS. 5, 7 and 8, when the housing 74 and the guide block 72 are fixed to both sides of the feed roll 20, the feed roll 20 is formed of a housing ( The housing 74 is integrally rotated together with the feed roll 20 when the straight roll is moved inside the 74 and the hot rolled plate 10 enters and the feed roll 10 is driven. Guide rolls 77 are installed on the inner circumferential surface of 74.

That is, the guide roll 77 is fixedly positioned at an angle, that is, 120 degrees, on the inner circumferential surface of the housing 74, and when the pair of brackets 78 are installed, a mounting groove formed in the center of the brackets 78. First, the plate spring 82 is fixed to the lower portion 80 and the rectangular rectangular bushing 84 is seated thereon. Then, the guide rolls 77 are inserted into the bushing 84, and then the bushing 84 is mounted. The cover plate 86 is screwed to the upper portion of the, it is important that the guide rolls 77 are installed in the linear movement direction of the feed roll (20).

Therefore, as shown in FIGS. 7 and 8, when the initial feed roll 20 is inserted into the housing 74, guide rolls 77 installed in the same direction as the insertion direction guide the feed roll 20. After the insert is fixed, the hot rolled sheet 10 is brought into contact with the guide block 72 fixed to the front surface of the housing 74 such that the hot rolled sheet 10 is guided. As a result, the guide rolls 77 in a direction perpendicular to the rotational direction of the feed roll 20 rotate integrally by friction with the surface of the feed roll.

That is, the housing 74 rotates by friction between the guide rolls 77 and the outer circumferential surface of the transfer roll 20, and thus, the guide block 72 coupled to the front surface of the housing 74 integrally rotates. While guiding the side edge portion of the hot rolled plate (10).

Accordingly, the guide plate 72 is guided while rotating while the hot rolled sheet 10 is fixed in a fixed state, thereby minimizing friction between the guide block 72 and the hot rolled sheet 10. This is to prevent the winding process from being poor after the chip.

At this time, as shown in Figure 8, the guide rolls 77 are able to flow in the vertical direction for the elastic force of the leaf spring 82 to reduce the excessive impact with the transfer roll 20, the leaf spring Although 82 is used, it is also preferable to use guide balls in which spring is loaded instead of guide rolls 77. The bushing 84 is provided with a protrusion and groove structure that is not shown in the drawing but is not detached from the bracket 78. It is desirable to have.

In addition, during the rotational movement of the housing 74, the upper guide block 56 of the connecting means 50 inserted into and fixed to the outer circumferential guide groove 76 also smoothly rotates by a bearing interposed therein while the housing 74 To guide).

As a result, by adjusting the hot rolled sheet 10 with a proper force before the winding operation so that the transfer line coincides with the winding center, not only the guide operation of the hot rolled sheet 10 but also chip generation are prevented.

As described above, according to the present invention, the hot-rolled sheet guide device of the present invention smoothly guides the hot-rolled sheet being conveyed before the winding operation of the hot-rolled sheet, which has undergone the hot rolling process, to the center of the conveying line, as well as the specific guide device in the conveying direction of the conveyed hot-rolled sheet. By rotating and guiding, chip generation due to over contact between the guide device and the hot rolled sheet is minimized to prevent surface breakage of the winder and the hot rolled sheet due to the chip, and thus the product quality of the hot rolled sheet and the coil wound thereon. To improve.

In addition, the hot rolled sheet is not guided by excessive force, thereby preventing damage to the guide apparatus due to the edge of the hot rolled sheet, thereby greatly extending the life of the guide apparatus, and having an excellent effect of easily repairing and maintaining the equipment.

While the invention has been shown and described with respect to specific embodiments thereof, it will be apparent to those skilled in the art that various changes and modifications can be made without departing from the spirit or scope of the invention as set forth in the claims below. I would like to know that those who have knowledge of this can easily know.
