Abstract

PURPOSE:To increase the pressure receiving area of the thrust forces acting upon bearing boxes through work rolls and to increase shifting length by using rotatable blocks in place of semicircular liners at the preceding ends of the bearing boxes mounted with work rolls. CONSTITUTION:Pillow blocks 5 are contained via a pins 6 in bearing boxes 3, 4 holding the work rolls 1, 2 contained in housing 12. On the other hand, brackets 13 hold clamps 10 and cylinders 11 via pins 9 and are held in the housing 12. If the rods of cylinders 11 are moved to the head side in the case of shifting the roll to the state of 2, the clamps 10 shift the boxes 3 to the position 4 via the pins 6 while grasping clamps 7 and blocks 5 via the pins 9. Since the blocks 5 are in contact with the clamps 7, 10 on planes, the thrust force per unit area is decreased. Since the blocks 5 are supported by means of the pins 6, longer shift length is taken.

Description

【発明の詳細な説明】 本発明は作業ロール移動装置に係り、特に、軸受箱にか
かるスラスト力の受圧面積の拡大による摩耗の苅処及び
ロングシフトに好適な作業ロール移動装置に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a work roll moving device, and more particularly to a work roll moving device suitable for long shifts and for reducing wear due to an enlarged pressure receiving area of thrust force applied to a bearing box.

従来の作業ロール移動装置は、第１図の５Ａのように、

又、シフト長さも多くとれない欠点があった。The conventional work roll moving device, as shown in 5A in Fig. 1,
Since the liner was in the shape of a kamabok, the thrust load applied to the bearing box 3.4 caused severe wear on the liner.
Also, there was a drawback that the shift length could not be increased.

くする作業ロール移動装置を提供するにある。SUMMARY OF THE INVENTION An object of the present invention is to provide a work roll moving device that increases the pressure receiving area of the thrust force applied to the bearing box via the work rolls and increases the shift length.

により、クランプ１０に保持されている。An embodiment of the present invention will be described below with reference to FIGS. 2 and 3. The housing 12 contains a bearing box 3.4 which holds the work roll 1.2. A block 5 is housed in the bearing box 3.4 via a pin 6. On the other hand, the bracket 13 holds the clamp 10 and the cylinder 11 via the pin 9, and is held by the housing 12. Further, the clamp 7 and cylinder 8 are held by a clamp 10 with bolts and brackets.

ているため、シフト長さが多くとれる効果がある。When shifting work roll 1 to work roll 2,
When the rond of the cylinder 11 is moved to the heside side, the clamp 10 shifts the bearing box 3 to the position of the bearing box 4 via the pin 6 with the clamp 7 and block 5 sandwiched therebetween via the pin 9. According to this embodiment, since the block 5 is in plane contact with the clamp/7.9, the thrust force per unit area is reduced. Further, since the block 5 is supported by the pin 6, there is an effect that a long shift length can be obtained.

本発明によれば、スラスト受のブロックの窄耗が少ない
ため、ブロック交換回数が少なくなり経済的である。又
、シフト量が多くなれば圧延材幅の種類が多く作れる効
果がある。According to the present invention, since the block of the thrust receiver is less worn out, the number of block replacements is reduced, which is economical. Furthermore, if the shift amount is increased, there is an effect that more types of rolled material widths can be produced.
