Abstract

The present invention relates to an apparatus for guiding a sheet material fed on a feed roll to a calibrating machine, the apparatus comprising: a frame unit spaced apart from both sides of the feed roll; And a leading unit disposed on a rear surface of the frame unit and leading the sheet material to the calibrating unit.

Description

{Apparatus for leading plate}

[0001] The present invention relates to a device for guiding a sheet material, and more particularly, to a device for guiding a sheet material to be bent in an upward direction when the sheet material is bent upward.

In a steel manufacturing process, a slab, which is a high-temperature material produced by a casting process and passed through a heating furnace, is produced as a rear plate having a predetermined thickness through a rolling process such as rough rolling and finish rolling.

Such a plate material is subjected to an accelerating cooler, which is a cooling device, to improve the strength, and after cooling, it is passed through a calibrator to produce a final thick plate.

The plate-like material passing through the cooling process and passing through the calibrator is an undesirable phenomenon, and upward bending occurs. Such a phenomenon causes a problem of moving to a roller or the like of the calibrator in the course of entering the calibrator.

FIG. 1 is a schematic view of a conventional facility showing a phenomenon in which a plate-like material fed on a conveying roll is upwardly bent and collision occurs without being properly drawn into a calibrator.

As shown in FIG. 1, the tip portion of the plate, which is the plate-like material 1, is bent upward due to various factors, but no separate adjustment means for stably correcting it is disclosed.

As a result, a process for additional flatness or warpage is required while passing through a separate correction line. Such a work itself not only lowers the productivity of a steel manufacturing process, but also complicates equipment and unnecessarily costs.

Figure 3 is a partial enlarged view of the leading unit of Figure 2; 4 is a perspective view showing a plate-shaped workpiece guiding apparatus according to an embodiment of the present invention. 5 is an exploded perspective view showing a plate-shaped workpiece guiding apparatus according to an embodiment of the present invention.

The sheet material guiding apparatus according to the present invention is a device for guiding a sheet material 1 fed on a conveying roll 2 into a calibrating machine 10, comprising a frame unit 110; And a leading unit (120).

First, as shown in Fig. 2, the frame unit 110 is arranged on both sides of the conveying roll 2 and spans up to the top of the conveying roll 2. [

The frame unit 110 supports most of the components described below, and preferably has a strength enough to withstand the loads of these supporting structures.

The reading unit 120 is designed to allow the sheet material 1 to be drawn into the calibrator 10 naturally while being brought into contact with the sheet material 1 in which the upward bending phenomenon occurs. And is disposed on the back surface of the unit 110.

Here, the rear surface refers to the surface of the frame unit 110 facing the calibrator 10, that is, the surface in the same direction as the moving direction of the plate-like material 1.

In the case of the frame unit 110, a pair of vertical bars 111, as shown in Figs. 2, 4 and 5, are provided so as to have the above-described supporting function and the holding function of the reading unit 120; And a loop 112.

Here, as shown in Fig. 2, the vertical bar 111 is arranged vertically and vertically apart from both ends of the conveying roll 2.

And the upper end of the vertical bar 111 may be configured to be interconnected by a loop 112 such that the loop 112 is not bar shaped but may cover the feed roll 2 like a roof, So as to be spaced apart from the upper portion of the feed roll 2 and the plate-like material 1. [

As shown in FIG. 3, the reading unit 120 has a predetermined angle in order to lower the impact with the upwardly bending plate-like material 1 which is in contact with the plate material 1, An acute angle and an obtuse angle with respect to the advancing direction of the plate-like material 1 are preferably formed, and the obtuse angle is preferably from 150 to 170 degrees.

First, when the obtuse angle is less than 150 degrees, the phenomenon that the plate-like material 1 having the upwardly bent portion collides with the reading unit 120 perpendicularly is undesirable, and when the obliquely angle is more than 170 degrees, However, there is a problem that the reading unit 120 needs to be elongated unnecessarily.

In the case of the reading unit 120, it may include a leading plate 121 to have the function as described above.

The leading plate 121 has an angle as shown in FIG. 3, and contacts the plate-like material 1, so that the plate-like material 1 can be correctly drawn into the straightening device 10.

One end of the leading plate 121 is hinged to the rear surface of the frame unit 110, and the other end of the leading plate 121 can be configured to contact the plate-like material 1 by its own weight.

In addition, the reading unit 120 may further include a leading cylinder 122, which is a structure capable of expanding and contracting its length, such as a hydraulic cylinder.

The upper part of the reading unit 120 is attached to the frame unit 110 and the lower part of the reading unit 120 is provided at the other end of the leading plate 121 so that the leading plate 121 is brought into contact with the plate- To provide a pressing force to be able to. That is, although the leading plate 121 may contact the plate-like material 1 by its own weight, the leading cylinder 122 acts so that constant force and constant contact can be maintained.

The lower surface of the leading plate 121, that is, the portion facing the sheet-like material 1, may include a leading roller 123. As shown in FIGS. 3 and 4, the leading roller 123 may be composed of an idler roller that is rolled according to the contact of the plate-like material 1. [

2, the present invention may further include a guide unit 130 as an auxiliary to the reading unit 120. As shown in FIG.

The guide unit 130 has a configuration in which the sheet-like material 1 having an upwardly bending phenomenon is guided by the reading unit 120 at a more relaxed angle.

The guide unit 130 is disposed on the front surface of the frame unit 110 and includes a guide plate 131, And a guide cylinder 132.

One side of the guide plate 131 is hinged to the vertical bar 111 in more detail than the frame unit 110 and the other side is connected to the guide cylinder 132.

The guide cylinder 132 has a function of raising or lowering the other end of the guide plate 131. The guide cylinder 131 is a kind of hydraulic cylinder and adjusts the upward flow of the other end of the guide plate 131 by the expansion and contraction of the length.

The sheet material guiding apparatus according to the present invention may further include a cooling unit 140 as shown in FIG.

The cooling unit 140 is disposed so as to be spaced apart from both sides of the conveying roll 2 and injects a cooling liquid, that is, cooling water, toward the plate-

As shown in FIG. 5, the cooling unit 140 includes an injection nozzle 142; And a cooling water supply unit 141. First, a plurality of the injection nozzles 142 may be provided. The injection nozzles 142 are opposed to the plate-like material 1 and spray a cooling liquid.
