本考案はワークロールをその軸心方向にシフト
し、この状態でロールベンデイングする様にした
圧延機のロールベンデイング装置に関する。[Detailed Description of the Invention] The present invention relates to a roll bending device for a rolling mill that shifts a work roll in its axial direction and bends the roll in this state.
圧延板はロールの熱分布等によつて圧延板の幅
方向板厚分布が様々なパターンで不均一となるこ
とがあり、又圧延板の板幅も狭幅のものから広幅

記種々の状況に対処し得る形状制御能力が要求さ
れる。 Rolled plates may have uneven thickness distribution in the width direction in various patterns due to the heat distribution of the rolls, etc., and the width of rolled plates also varies from narrow to wide. It is in. Therefore, rolling mills are required to have shape control capabilities capable of dealing with the various situations mentioned above.

なベンデイング荷重を得ることができなかつた。 A reaction force receiving beam d provided in the housing c allows the work rolls a and b to slide in the axial direction.
The bending load was applied by pressing hydraulic pistons e and f against the cylinder. However, in the case of this method, since the pushing positions of the hydraulic pistons e and f change due to the axial sliding of the work rolls a and b, strain is placed on the reaction force receiving beam d, and it is difficult to maintain a uniform bending load. I couldn't get it.

ことを特徴とするものである。 The present invention has been made to correct such problems, and is a rolling mill that shifts the work rolls in the axial direction of the work rolls. A block is fitted into the recessed portion by interposing a pressure fluid, and appropriate sloped portions are provided at both corners of the surface of the support block opposite to the recessed portion, and a pair of opposing wedge blocks are fitted into the sloped portion. This invention is characterized in that the wedge blocks are connected to a driving device that causes the wedge blocks to approach and separate from each other.

平方向に移動可能に構成する。 A semicircular recess 14 having a diameter slightly larger than the outer diameter of the neck 11 is formed in the support blocks 12 and 13, and an oil reservoir 15 of a required depth is provided along the inner surface of the recess 14. A sealing material 18 is arranged around the oil reservoir chamber 15 so as to communicate the oil supply path 16 and the oil return path 17. Then, connect the recess 14 to the neck 1.
1 to make the oil reservoir chamber 15 liquid-tight, and further supply pressurized oil to the oil reservoir chamber 15 through the oil supply path 16 to reduce the load acting between the necks 11, 11 and the support blocks 12, 13. Make it supportable. Both corner portions of support blocks 12 and 13 facing each other are cut out at appropriate slopes, and wedge blocks 19 and 19 are wedged into the slope portions. Further, a cylinder 20 is connected to the wedge block 19, and the cylinder 20
The wedge blocks 19, 19 are configured to be movable in the horizontal direction by the operation of the wedge blocks 19, 19.
次に上記構成に於けるベンデイング作動を説明

望の状態に制御することができる。 Pressure oil is supplied to the oil reservoir chamber 15 from a pressure oil source (not shown) via the oil supply path 16, and is returned to the oil tank or the like through the return oil path 17 while maintaining the oil reservoir chamber 15 at a required pressure. Next, the upper and lower work rolls 3 and 4 are shifted to required positions by a roll shift device (not shown) (see FIG. 3), and rolling is performed. Next, depending on the shape of the rolled plate 21, the cylinder 20 is driven to move the wedge blocks 19, 19.
The wedge engagement depth between support blocks 12 and 13 and support blocks 12 and 13 is changed. Due to this change in wedge depth, the distance between support blocks 12 and 13 changes,
The bending state of the upper and lower work rolls 3 and 4 can be controlled to a desired state.

できる。 Furthermore, the distance between support blocks 12 and 13 is
Since it is determined by the wedge depth of the wedge block 19, by detecting the horizontal position of the wedge block 19 and adjusting the pressure of the cylinder 20 with a pressure regulating valve or the like 22, the pressure of the support blocks 12, 13 can be adjusted. The position is determined. That is, the block position is determined by the cylinder 20, and the work roll bending load is determined by the supply pressure of the oil reservoir chamber 15, which is different from the conventional bearing box type work roll bending. Incidentally, a conventional bearing box type work roll bending system is shown in FIG. 6, for example. 22 and 23 are upper and lower work rolls 3 and 4
The axle box 23 (or 22) has a built-in hydraulic piston 27 that applies a load for roll bending, and pressurized oil is supplied to the piping 26 and the hydraulic piston 27. The work roll bending load is supplied through the valve 25 and the work roll bending load is set by the hydraulic valve 25. Therefore, in this system, the role of applying the bending load is performed by the hydraulic piston 27, and the position of the block containing the hydraulic piston 27, that is, the axle box 23, is fixed at the position of the roll neck 11 via the bearing 24. ing. Furthermore, as is clear from their structure, the support blocks 12 and 13 support the vertical load acting between the necks 11 and 11 and the support blocks 12 and 13, but the axial directions of the upper and lower work rolls 3 and 4 are completely free. Therefore, the work roll can be shifted extremely smoothly, and the bending force on the work roll can be applied directly to the work roll.
