Description

[Detailed Description of the Invention] [Industrial Field] The present invention relates to a plate holding device for preventing buckling of a rolled plate during width reduction by an edger.

[Prior Art] Conventionally, width reduction of a rolled plate has been carried out using an edger.

[Problems to be solved by the invention] However, when the rolled plate is width-reduced by an edger, buckling is likely to occur if the rolled plate is thin, and for this reason, the flat surface of the rolled plate being width-reduced by the edger is held down by a roll. Although it has been considered to use a presser roll, it is difficult to install a presser roll and a device for operating it on the pass line of an existing rolling mill.

The present invention has been developed in view of these conventional problems, and is intended to simplify the equipment by attaching the presser roll to the rolling mill housing.

[Means for Solving the Problems] The present invention is an attempt to solve the above-mentioned technical problem, and includes a main shaft rotatable in the housing of the rolling mill at the upper part of the edger provided on the entrance side of the rolling mill. In addition, a presser roll configured to press the flat surface of the rolled plate near the width reduction position by the edger is attached to the main shaft via an arm, and further the main shaft is rotated via a lever, and the rolled plate is removed by the presser roll. The present invention relates to a plate holding device characterized in that a hydraulic cylinder for pressing and releasing the plate is attached to the housing.

[Function] Therefore, in the present invention, by operating the cylinder attached to the housing, the presser roll is rotated up and down via the main shaft and arm attached to the housing, and the area near the lower part of the width compression by the edger is pressed. buckling of the rolled plate can be prevented.

[Example] An example of the present invention will be described below based on the drawings.

As shown in FIGS. 1 and 2, on the entry side of the rolling mill 1, the vertical rolls 3 are
An edger is provided to reduce the width of the rolled plate 4 through the edge.

Further, the rolling mill housing 5 above the edger
A main shaft 6 parallel to the rolling plate 4 is rotatably provided on the front surface by a support fitting 7, and a hydraulic cylinder 9 is attached to the housing 5 by a bracket 10, and the main shaft 6 is rotated via a lever 8. . Further, a presser roll 11 for preventing buckling of the rolled plate 4 is attached to the main shaft 6 via an arm 12.

The presser roll 11 is misaligned with respect to the vertical roll 3 when the rolled plate 4 is pressed, so that even if the width of the rolled plate 4 changes, the presser roll 1
1 makes it possible to always keep the full width down. Further, the main shaft 6 is provided at a height that also serves as a guide for the rolled plate 4, as shown in FIG. 13 in the figure is a plate biting signal 14 of the rolling mill 1
A reduction signal 15 is sent to the hydraulic pressure reduction cylinder 2.
and a command device which outputs a presser signal 16 to the rotating hydraulic cylinder 9, respectively, and 17 is a guide plate.

When the rolled plate 4 enters the rolling mill 1, the presser roll 11 is rotated upward as shown in FIG. Waiting in the designated position.

At this time, the main shaft 6 and the arm 1
2 can serve as a billy roll to guide the tip of the incoming rolled plate 4 to the guide plate 17 side if it is lifted up, or to prevent the rolled plate 4 from jumping up. In order to perform this action more effectively, a freely rotatable collar 18 may be provided around the main shaft 6, as shown in FIG.

The rolled plate 4 is bitten by the rolling machine and the rolled plate 4 is
When tension is generated, the cylinders 2 and 9 are actuated by the signals 15 and 16 sent by the command device 13, and the width reduction by the vertical roll 3 and the presser roll 11 are performed.
At the same time, buckling is prevented by pressing.

As described above, since the presser roll 11 and the device for operating it are attached to the housing 5, it can be easily applied to existing rolling mills.

Note that the present invention is not limited to the above-mentioned embodiments, and various changes may be made without departing from the gist of the present invention.

[Effects of the invention] As described above, according to the plate holding device of the present invention, the plate holding device consisting of a presser roll and a device for operating the presser roll is attached to the rolling mill housing. It can be easily applied as a plate holder for an edger between stands, etc., and can have an excellent effect in that the rolled plate can be simultaneously guided by the main shaft and arm attached to the housing.
