本発明は圧延機に係り、特に操作側又は駆動側ハウジン
グの一方がロール軸方向に移動する移動側ハウジングの
移動、固定に好適な圧延機に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a rolling mill, and particularly to a rolling mill suitable for moving and fixing a movable housing in which either an operating side housing or a driving side housing moves in the roll axis direction. It is related to.

寄せる装置が設けてなかった。In conventional rolling mills, as described in Japanese Patent Application Laid-Open No. 54-139866, the movement of the moving side housing is a sliding movement due to surface contact, and the path between the moving side housing and the housing shoe (rolling There was no device installed to shift the gap in the direction of material passage) to one side.

グの高さ方向の相違が生じやすく、このため、ロールの
レベリングが悪く、また、窓面の位置ずれのため、ロー
ルが傾き、圧延材が蛇行しやすいという問題があった。The above conventional technology does not take into consideration the wear of the moving housing and the alignment of the window surfaces of the fixed housing and the moving housing, which tends to cause a difference in height between the fixed housing and the moving housing. There was a problem in that the leveling of the rolls was poor and the rolls were tilted due to the positional shift of the window surface, making the rolled material easy to meander.
本発明の目的は、移動側ハウジングの摺動面が摩耗した

延材が蛇行することがないようにできる圧延機を提供す
ることにある。SUMMARY OF THE INVENTION An object of the present invention is to provide a rolling mill that prevents the rolling material from meandering due to wear of the sliding surface of the moving housing or poor alignment of the window surface of the stationary housing. .

した構成として達成するようにした。The above object is such that the upper surface of the housing shoe and the moving housing are in surface contact during normal times other than when the moving housing is moving, and when moving, the moving housing has a floating device and a roller that can roll and move. This is achieved by equipping the housing shoe or the moving housing with a hydraulic cylinder for moving the moving housing and bringing the moving housing into contact with one side of the inlet or outlet housing shoe.

る。The moving side housing usually has a wide surface in contact with the top of the housing shoe, and when moving, the rollers installed on the moving side housing are pressed with a floating device to separate the surfaces that are normally in contact, and the moving side housing is placed in several pieces. Lift it up with rollers and move the moving side housing in this state. Therefore, it is possible to eliminate wear on the upper surface of the housing shoe and the contact surface of the moving side housing, and also to maintain a gap in the path direction between the moving side housing and the housing shoe so that the window surfaces of the fixed side housing and the moving side housing match. Since the housing shoe or the moving side housing is equipped with a hydraulic cylinder that moves to one side, the inclination of the rotor can be eliminated and the meandering of the rolled material can be prevented.

In FIG. 7, the solenoid valve 32 is switched to move the cylinder 21 backward, and then the spacer 22 is opened as shown in FIG. Next, the block 14 is moved back by the cylinder 13 shown in FIG. 5, and the cylinder 12 shown in FIG. 4 is also moved back. Next, as shown in FIG. 6, which is a cross-sectional view showing the state in which the housing 1 in FIG. , as shown in FIG. Natsuto 35
Then, the operation side housing 1 is moved toward the drive side housing 2 by the cylinder 5 held on the bracket 6 fixed to the foundation. The wheels 16 rotate on a highly hard liner 11 (see FIG. 6) attached to the upper surface of the housing shoe 4. Further, since the wheel width is less than a fraction of the contact width between the operation side housing 1 and the housing shoe 4, the mounting height of the operation side housing 1 does not change even if this width is worn out.
