【発明の詳細な説明】
［産業上の利用分野］
本発明は、バーチカルエツジヤーの押えロール
装置に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a presser roll device for a vertical edger.
［従来の技術］
従来、例えばホツトストリツプミルの粗ミル又
は仕上ミルの入側に設置のバーチカルエツジヤー
において板材の幅圧下を行う時、押えロールがな
い場合板材が座屈しない限界内に幅圧下量を制限
して圧延を行うか、より強幅圧下を行う場合に
は、板材の座屈を防止するため、板材を押えロー
ルによつて上下から挟持するようにしている。[Prior Art] Conventionally, when reducing the width of a plate material using a vertical edger installed at the entry side of a hot strip mill or a finishing mill, for example, if there is no presser roll, the plate material cannot be rolled within the limit without buckling. When rolling is performed with a limited width reduction amount or when a stronger width reduction is performed, the plate material is clamped from above and below by presser rolls in order to prevent buckling of the plate material.
［発明が解決しようとする問題点］
しかしながら、前記押えロールは単に板材の幅
方向中央位置に配置する構成としてあるため、板
材の板厚や板幅が変化した場合、最適位置にて座
屈の発生を防止していることにはならなかつた。[Problems to be Solved by the Invention] However, since the presser roll is simply arranged at the center position in the width direction of the plate material, when the thickness or width of the plate material changes, buckling can be prevented at the optimum position. This did not mean that the outbreak was being prevented.
一方、板材の先端及び尾端の非定常部（先・尾
端から数ｍ）はエツジヤー及びミルでの圧延にお
ける塑性流動が定常部（中央部）と異なり特異な
形状（第３図、第４図）となるため、オフゲージ
量が多くなり歩留低下の原因たなつている。 On the other hand, the unsteady part (several meters from the tip and tail) of the tip and tail of the plate material has a unique shape (Fig. 3, 4 As a result, the amount of off-gauge increases, which is the cause of a decrease in yield.
又、前記押えロールは、板材の先端が竪ロール
間に噛込んでからはじめて板材を挟持するように
しているので、板材の先端部には板幅変動をなく
し、板幅精度と歩留向上を図るための強幅圧下を
掛けることができず、そのため、第３図に示すよ
うに、板材ａの先・尾端部にはバチ形部分ｂ、又
は第４図に示すような先細り部分ｃが形成されて
しまい、この特異な形状部分は切断する必要があ
ることから、歩留りの低下をもたらしていた。 In addition, the presser rolls clamp the plate only after the tip of the plate is caught between the vertical rolls, so the tip of the plate can eliminate plate width fluctuations and improve plate width accuracy and yield. Therefore, as shown in Fig. 3, the tip and tail ends of plate material a have a drumstick-shaped part b, or a tapered part c as shown in Fig. 4. This uniquely shaped portion needs to be cut, resulting in a decrease in yield.
本発明はこのような実情に鑑み、板材の先・尾
端の塑性流動を予測し、特に第３図に示すバチ型
形状を補正するため、座屈を発生させることなく
板材の先端から直ちに強幅圧下を掛けられるよう
にしたものである。 In view of these circumstances, the present invention predicts the plastic flow at the tip and tail of a plate, and in particular, in order to correct the drumstick shape shown in Fig. 3, it is possible to immediately strengthen the plate from the tip without causing buckling. This allows width reduction to be applied.

In addition to arranging multiple sets, the upper presser roll is supported by a reduction cylinder operated by the drive of a servo valve, and each presser roll is connected to a shift cylinder installed in the housing, and each presser roll is moved by the expansion and contraction movement of the shift cylinder. The rolls are configured so that they can each move in the width direction of the plate, and a tip position detector for detecting the tip position of the plate is installed at a position upstream of the vertical edger, and furthermore, a signal from the detector and a plate transfer speed are installed. The servo valve has a configuration including a controller that calculates the signal and sends a drive command to the servo valve.

The movement position of this presser roll is selected to be a position that improves the buckling limit in accordance with the thickness and width of the plate material. Also, when the position of the tip of the plate is detected by the position detector, a drive command is sent from the controller to the servo valve, the reduction cylinder is activated, and the presser roll that was waiting is lowered by a predetermined amount to clamp the plate. . As a result, the plate material is subjected to a strong width reduction from the tip.

係合せめてある。 FIGS. 1 and 2 show an embodiment of the present invention, in which vertical rolls 3, 3 supported on the window portions of upper and lower housings 1, 2 via axle boxes are moved by lowering mechanisms 4, 4. The plate material 5 is constructed so that it can approach and move away from each other, and is axially rolled down by the vertical rolls 3, 3.
Two sets of upper and lower presser rolls 6 and 7 are arranged in the width direction of the plate so as to sandwich the plate from above and below, and the upper presser roll 6 is equipped with a servo valve so that the interval between the presser rolls 6 and 7 can be adjusted according to the plate thickness. A shift cylinder is connected to a lowering cylinder 9 driven by the lowering cylinder 8, and is configured to be able to raise and lower the upper presser roll 6 via a guide 10 by the expansion and contraction movement of the lowering cylinder 9, and the guides 10 are respectively installed in the upper housing 1. 11 so that the upper presser roll 6 can be moved in the sheet width direction by the telescoping movement of the shift cylinder 11. Furthermore, a shift cylinder 12 installed in the lower housing 2 is also connected to the lower presser roll 7. , so that it can similarly move in the board width direction. Incidentally, both the upper and lower pressing rolls 6 and 7 are engaged with a movement guide (not shown) in the width direction of the sheet.

When 1 and 12 are expanded and contracted, the upper and lower presser rolls 6 and 7
are respectively moved to arbitrary positions in the board width direction. Therefore,
When rolling down the width of the plate material 5 with the vertical rolls 3, 3, the position of the material 5 to be clamped is adjusted according to the thickness and width of the plate material 5.
It is possible to select a position where buckling is likely to occur. Therefore, the buckling limit of the plate material 5 is improved.

れる。 On the other hand, before the plate material 5 reaches the vertical rolls 3 and 3 of the vertical edger, the upper presser roll 6 is set at a distance of the plate thickness + α from the lower presser roll 7. When the plate 5 is transferred in this state and the position of the tip of the plate 5 is detected by the position detector 13, the signal is input to the controller 15, where it is calculated as the speed signal 14. A drive command is sent to the servo valve 8. In the servo valve 8, the plate material 5 is a vertical roll 3,
When the third part is reached, the cylinder 9 is actuated, and the presser roll 6 descends almost simultaneously with the biting of the plate material 5, and presses the plate material 5.
be held from above and below. Therefore, the upper and lower surfaces of the plate material 5 are restrained when the tip ends are bitten by the vertical rolls 3, 3.

切断長さが短くなり歩留りが向上する。 As described above, the plate material 5 can be subjected to a strong width reduction immediately from its tip without causing buckling, and a large amount of width reduction can be achieved. In addition, since a strong width reduction is applied from the tip, the drumstick-shaped portion b shown in FIG. improves.
