As a conventional vertical rolling mill, there is one shown in FIG. 1 and FIG. 2, which is shown in the direction of the - arrow in FIG. 1. In the figure, 1 is a rolled material such as a slab, and both sides of the rolled material 1 are subjected to wide reduction rolling by vertical rolls 2, 2, and the upper end is connected to a spindle 3, and the vertical rolls 2, 2 Roll jocks 4, 4 supporting the housing 5 are mounted on both the upper and lower sides of the housing 5 so as to be movable in the horizontal direction.

を行なうことができる。 In FIG. 2, reference numeral 6 denotes a reduction screw connected to the roll chock 4, which is screwed into a reduction nut 9 housed in a nut case 8 fixed to the housing 5 with a keeper plate 7 so as to be slidable in the axial direction. The roll gap of the vertical rolls 2, 2 is set by the amount of screw engagement. In addition, 10 is a responsive hydraulic cylinder that advances and retreats the reduction nut with a force that overcomes the rolling reaction force in order to eliminate strip width fluctuations caused by skid marks during rolling.

ウトするのが通常である。 When carrying out wide reduction rolling of a rolled material 1 such as a slab using a vertical rolling mill with such a configuration, a horizontal rolling mill for correcting dog bones on both edges of the slab caused by wide reduction rolling is placed in a position close to the downstream side of the line. It is usually laid out.

強固に連結するためのポストである。 FIG. 3 is a plan view schematically showing the housing 5.
5a and 5b are posts for firmly connecting an adjacent horizontal rolling mill (not shown).

発生し、この作用力はハウジング５に大きな影響
を与える。 During rolling, a rolling reaction force P is applied to the housing 5.
acts, and the rolling speeds of the horizontal and vertical rolling mills are different, so an acting force that pushes or pulls each housing is generated between the two rolling mills, and this acting force has a large effect on the housing 5. give.

ン上流側方向への作用力F2が負荷される。 That is, when the rolling speed of the horizontal rolling mill is high,
The housing 5 is loaded with an acting force F 1 in the downstream direction of the line using the posts 5a and 5b as the points of force, and conversely, when the rolling speed of the vertical rolling mill is high, the force is applied on the bonding points of the roll jocks 4 and the housing 5 as the points of force. An acting force F 2 is applied in the upstream direction of the line.

トのアームとなり、各々の長さをl1，l2とする。 Here, beams 5 located on both sides of the housing 5
The distances from the inner end surfaces 5c' and 5d' of portions c and 5d to the respective force points become arms of bending moment based on the acting forces F 1 and F 2 , and the respective lengths are defined as l 1 and l 2 .

重量及び容量が大きく、装置据付時の施工性が悪
くまた圧延機長も長くなるという問題がある。 Generally, in a vertical rolling mill, since the opening dimension lw of the housing window W is long, the above-mentioned bending moment arms l 1 and l 2 also become large, and when the acting forces F 1 and F 2 are applied, the housing 5 is bent to a large extent. Moment acts. Therefore, in order to withstand this load force, the rigidity of the housing 5 must be increased, the dimensions of each part must be increased, the weight and capacity of the device are large, and workability during installation of the device is poor. There is also a problem that the length of the rolling mill becomes longer.

It is an object of the present invention to reduce the capacity of the having housing by substantially reducing the frontage dimensions of the housing window and by reducing the length of the bending moment arm under the applied force to reduce moment forces.

The configuration of the present invention is that, in a vertical rolling mill, openings to which hydraulic cylinders for rolling reduction adjustment can be attached are provided on both sides of the housing window, and a rolling nut is installed between the end of the housing window and the opening. It is equipped with a lowering nut mounting section for mounting.

ことができる。
In the vertical rolling mill according to the present invention, since the rolling nut mounting portion is integrally formed with the housing, the frontage size of the housing window can be made small, and the load is applied in correlation with the rolling speed of the horizontal rolling mill attached thereto. Since the distance to the point of force, that is, the length of the bending moment arm can also be reduced, the load force on the housing can be reduced. Therefore, since the bending moment can be reduced for the same amount of acting force, the housing can be designed with low strength, and the weight and capacity of the housing can be reduced.
以下、第４図に示す実施例に基いて本考案を説
明する。
The present invention will be explained below based on the embodiment shown in FIG.
同第４図はハウジング５の概略を示す平面図で
左右対称に形成され、中央に間口寸法Lwのハウ
ジングウインドウＷ、及び両側に油圧シリンダ１
０内蔵用の開口部２０，２０を設けている。 FIG. 4 is a plan view schematically showing the housing 5, which is formed symmetrically, with a housing window W with a width Lw in the center, and hydraulic cylinders 1 on both sides.
Openings 20, 20 for storing 0 are provided.
そして、ハウジングウインドウＷ端部と開口部

ナツト９に圧下スクリユー９を螺合している。 A lowering nut mounting part 21 is formed between the end of the housing window W and the openings 20, 20, and a nut case 8 is disposed within the mounting part 21, and a lowering nut 9 is slidably mounted therein. , a reduction screw 9 is screwed into the same reduction nut 9.

容易に開口部２０内に着脱することができる。 A hydraulic cylinder 10 is attached to each of the openings 20, 20, and an actuator 10a receives pressure from the nut case 8. This hydraulic cylinder 10 alone can be easily attached to and removed from the opening 20.

部の強度はハウジングウインドウ部の強度と変わ
らない。 FIG. 5 is a cross-sectional view taken along the line -- in FIG. Therefore, the strength of the rolling nut mounting portion 21 is approximately the same as that of the beam 22 portion. On the other hand, the cross section of the rolling nut installation part of the conventional housing shown in FIG. 2 shows the rolling screw 6, the rolling nut 9, and the nut case, as shown in FIG. The entire portion where 8 is attached is hollow, so the strength of the rolling nut attachment portion is the same as the strength of the housing window portion.

法Lwは、第２図に示した従来のハウジングの間
口寸法lwに較べて、第２図におけるキーパプレ
ート７の間口寸法の２倍近く小さくなる。 In the housing 5 of this embodiment, the strength of the reduction nut mounting part 21 is almost the same as that of the beam 22, so the frontage dimension Lw of the housing window W is the same as the frontage dimension lw of the conventional housing shown in FIG. Compared to this, the frontage dimension of the keeper plate 7 in FIG. 2 is nearly twice as small.
ここで、第４図において、水平圧延機との相関
に基く作用力F1，F2の力点とハウジングウイン
ドウＷの端部２１ａ間の距離L1，L2は従来例の
曲げモーメントアームl1，l2よりも小さくなる。
従つて、作用力F1，F2が同じである場合、ハウ
ジング５に負荷される曲げモーメントを小とする
ことができ、同じ作用力に対してハウジング５の
剛性を小とすることができる。 Here, in FIG. 4, the distances L 1 and L 2 between the force points of the acting forces F 1 and F 2 and the end portion 21a of the housing window W based on the correlation with the horizontal rolling mill are the bending moment arm l 1 of the conventional example. , l becomes smaller than 2 .
Therefore, when the acting forces F 1 and F 2 are the same, the bending moment loaded on the housing 5 can be made small, and the rigidity of the housing 5 can be made small for the same acting force.
上記により、ハウジング５の各部寸法を小さく
でき、従来のものに比べ重量で10〜20％程度低減
することができる。 As a result of the above, the dimensions of each part of the housing 5 can be reduced, and the weight can be reduced by about 10 to 20% compared to the conventional housing.
また、油圧シリンダ１０の基端を受ける両端の
梁２２部分の間口幅も同様に従来のものに比べて
小となすことができる。これは圧下ナツト装着部
２１が作用力F1，F2に基づく曲げモーメントの
大半を受け、かつ、固定モーメントを大きくさせ
るため、圧延反力Ｐによる曲げモーメントが小さ
くなるためである。 Furthermore, the width of the frontage of the beam 22 at both ends that receives the base end of the hydraulic cylinder 10 can be made smaller than that of the conventional one. This is because the rolling nut mounting portion 21 receives most of the bending moment based on the acting forces F 1 and F 2 and the fixing moment is increased, so that the bending moment due to the rolling reaction force P becomes smaller.

Since the vertical rolling mill according to the present invention can reduce the weight and capacity by reducing the dimensions of each part of the housing,
Equipment costs can be reduced and installation work can be simplified.
