この発明は圧延ロールスラスト方向調整装置に
関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a rolling roll thrust direction adjusting device.
Ｈ形鋼は、一般に粗圧延機で造形された粗形Ｈ
形鋼を第１図に示すような上下の水平ロールＡ，
A′と左右堅ロールＢ，B′から構成されたユニバ
ーサルミルにより圧延することにより製造され
る。 H-beam steel is generally a rough shape H shaped using a rough rolling mill.
The section steel is rolled into upper and lower horizontal rolls A as shown in Figure 1.
It is manufactured by rolling with a universal mill consisting of A' and right and left hard rolls B, B'.
この上下水平ロールＡ，A′のセンターライン
に第２図に示すようなズレαが生じていると、圧
延後のＨ形鋼Ｘは第３図に示すように各フランジ
厚t1〜t4に偏差のあるものとなり、品質的に大き
な問題となる。 If the center lines of the upper and lower horizontal rolls A and A' have a deviation α as shown in FIG. 2, the H-shaped steel X after rolling has a thickness of each flange t 1 to t 4 as shown in FIG. 3. This results in a deviation in the quality of the product, which poses a major problem in terms of quality.
このズレの発生原因としては、ロール組入時の
誤差や圧延時のロールスラスト方向のズレ等があ

移動させてこのズレを解消していた。しかし手動
による方法では調整時間がかかること、調整精度
が良好でないことなどから製品のフランジ厚偏差
が発見された後の敏速かつ正確な調整を行うこと
は出来なかつた。 The causes of this misalignment include errors when assembling the rolls and misalignment in the roll thrust direction during rolling, but conventionally this misalignment has been resolved by manually moving the rolls in the thrust direction. However, manual methods require time for adjustment and have poor adjustment accuracy, making it impossible to perform prompt and accurate adjustment after a deviation in the flange thickness of a product is discovered.
本発明は上記した従来の欠点を改善するために

いる。 The tapered bodies 11 and 12 are tapered so that the upper side is wider and the tapered bodies are tapered toward the lower side. Tapered body 1
1 is inserted between the housing 1 and the choke yoke 4, and is configured to abut a protrusion 40 and sandwich the protrusion 40 between one pressing point 10a of the thrust holding device 10. The other tapered body 12 is inserted between the thrust holding device 10 and the housing 1,
It comes into contact with another pressing point 10b of the holding device 10. Each of the tapered bodies 11 and 12 is provided with a driving device 13 and 14, respectively, to move the tapered bodies 11 and 12 up and down, that is, to raise and lower them. Although motors or the like can be used as the drive devices 13 and 14, hydraulic cylinders are used in this embodiment.
次に使用方法を説明する。 Next, how to use it will be explained.

を押下げれば良い。 The case where the rolling rolls are moved in the direction of the arrow in FIG. 5 will now be explained. First, the left and right tapered bodies 11, 11 of the choke yoke 4 are pulled upward by the drive devices 13, 13. The amount of pulling up is determined depending on the required amount of movement of the rolling rolls. Tapered body 1
When 1 and 11 are pulled up, a gap is created between them and the protrusion 40. Next, the tapered bodies 12 and 12 are pulled up to
4 and 14, the thrust holding device 10 rotates and presses the protrusion 40 toward the tapered body 11 to move the choke yoke 4. This movement of the choke yoke causes the rolling roll to move in the direction of the arrow. To move the tapered bodies 11, 11 in the opposite direction, pull up the tapered bodies 12, 12.
All you have to do is press down.

る。 Note that the amount of movement of the rolling rolls may be adjusted with high precision by detecting the amount of displacement of the tapered body using a suitable sensor such as a magnescale and controlling the drive device in a feed pack manner. It is also possible to predict the amount of axial displacement of the rolls from the data of the previous pass, etc., and adjust the roll positions in advance by computer control.
