となっていた。Conventional rolling is generally performed in the longitudinal direction of the plate material, especially with respect to the rolling process of strip-shaped plate material wound in a coil shape, and there is no problem with the general rolling process by this method. Did not occur. However, when the demand for manufacturing various shaped parts by so-called rolling has become stronger recently, the longitudinal direction of a pair of work rolls, which is generally performed, or a pair of work rolls supported by a group of reinforcing rolls However, various rolling methods have come to be required.
In such special rolling, when trying to obtain a certain special shape, or when trying to obtain special material properties by combining rolling processing in the longitudinal direction and the width direction, etc. Unlike rolling, it becomes necessary to roll in a direction substantially perpendicular to the longitudinal direction. Conventionally, in the case of performing such widthwise rolling, as one method thereof, for example, as shown in FIG. 3, the material is longitudinally aligned with a, b, c, d, h ...
It is finely divided at the position shown by (a: cutting edge), each plate piece is rotated 90 degrees as shown by b, and the side faces c of the plate piece when divided in the longitudinal direction are welded together to form a long strip coil. However, there is a method of rolling this in a conventional method and rolling in a direction substantially perpendicular to the initial longitudinal direction. With this method, it is necessary to perform a huge number of welds one by one, and it is difficult to secure the straightness in the rolling direction required when performing the rolling work in the next process, and at the same time, the initial plate material Due to the non-uniformity of the cross-sectional shape (that is, the crown of the plate), rolling after welding is difficult, and problems such as fracture of the weld often occur in the subsequent rolling process, especially when the plate material is thin. However, it was difficult to process it efficiently. Further, in FIG. 4, the material 1 is placed on the surface plate 3 and the like, the rolling roll 2 is rolled in the direction 5 substantially at right angles to the longitudinal direction to act, and the material 1 is run in the direction 4 to achieve widthwise rolling. The method (for example, Japanese Patent Publication No. 62-45007) is shown. However, this method also has a problem that the processing is intermittent and therefore is not suitable for the thickness uniformity in the longitudinal direction and the efficient processing as in the former case. As described above, the conventional width direction rolling technique is not only inefficient, but also cannot be said to be a rational processing method in terms of ensuring the dimensional accuracy and shape of the product and the yield. For this reason, mass production is impossible, and the cost of the product that has undergone such processing is also very high.
上記した様に、従来の幅方向圧延技術では加工そのもの

を量産する為には、必ずしも適した方法とは言えなかっ
た。As described above, the conventional width-direction rolling technique can be processed, but it is not necessarily a suitable method for mass-producing high-efficiency and high-quality products.

事にある。The object of the present invention relates to a method of rolling a material, which is a drawback of the prior art, for example, a method of rolling materials joined by many welding, and a material by performing rolling in the width direction of a long material while continuously supplying the material. It is an object of the present invention to provide a width direction rolling method and an apparatus thereof in which the inefficiency of the method of feeding and rolling intermittently is remarkably improved.

A rolling mill S having an axis and a small-diameter roll 9 attached to a basket-type roll group 10 that continuously rotates in the width direction in a plane orthogonal to the longitudinal direction, and has a reduction mechanism between the upper and lower rolling rolls. Is a method for continuously achieving widthwise rolling. The lower roll 6 may be supported by a bearing used in a conventional rolling mill, or may be supported by a medium-convex backup roll. Further, a basket-type roll group 10 having a rotation axis parallel to the longitudinal direction of the long material and continuously rotating in the width direction within a plane orthogonal to the longitudinal direction has a drive shaft 7 at the center and a work roll 9 It is supported by a rotatable roll group supporting device 8 arranged so as to be installed in plural on the outer circumference, and the device has a reduction mechanism between the shaft 7 and the lower roll 6. The reduction mechanism may be installed on the lower roll 6 or the roll group supporting device 8. The upper work roll 9 is supported by a retainer (not shown) along the outer periphery of the roll group supporting device 8 and rotates while planetarily rotating.
The lower roll 6 and the planetary roll 9 are used for rolling.

達成する為には、上記それぞれのロールの直径比d/Dを

必要がある。The axis of the lower roll 6 and the roll 9 of the basket-shaped roll group is as shown in FIG. 6 (a roll 9 of the basket-shaped roll group is shown) in a plan view of the processing. It is almost at a right angle, and the plastic working area by both rolls becomes a quarter ellipse as shown in 13. Here, the plate material advances in the direction of 1a, and the rotation of the lower roll rotates together with the plate material as in 6a. Moreover, the roll 9 of the basket type roll group moves in the direction 14 at a substantially right angle to the plate material while rotating like 9a. FIG. 7 shows a side view of the processed state, and FIG. 8 shows a front view. From these figures, it is clear that in the processing method of the present invention, the shape of the plastic processing region, that is, the overall processing direction changes depending on the relationship between the diameter D of the lower roll and the roll diameter d of the basket type roll group. . FIG. 9 shows the state of changes in the plastic working region 13 depending on the respective roll diameters. The diameter d of the work rolls 9 of the basket type roll group is the lower roll (center concave roll) in the widthwise central portion. When the diameter is extremely small with respect to the diameter D, the plastic working region 13 (roll bite portion) becomes as shown in (1) of FIG. 9, and the widthwise rolling state can be almost achieved. Therefore, in order to achieve the meaning of widthwise rolling, it is necessary to set the diameter ratio d / D of each roll to 1 or less and increase the ratio of the plastic flow in the width direction of the plate material.

る。On the other hand, in the width direction rolling method of the present invention, the plate material is always pressed against both rolls, and one surface (the surface in contact with the basket-type roll group) is set in a direction that inhibits the progress of the plate material. Therefore, a forward tension is particularly required to advance the plate material. This tension is preferably 80% or less of the yield stress of the plate material in the processed state, though it depends on the kind of the plate material. If the tension is too high, problems such as breakage of the material are likely to occur.
On the other hand, if the tension is too low, the running of the material will be supported.

によるものである。The number of the rolls 9 held by the basket-type roll group 10 in contact with the material surface, that is, the number of constrained portions of the material is given to the material for keeping the traveling speed of the material or the processing speed of the material constant. Since it affects the tension, it is preferable that the processing speed is small. However, if the pitch of the rolls 9 along the outer circumference of the cage-type roll group supporting device 8 becomes wider than the width of the material to be processed, the meaning of continuous uniform processing becomes meaningless. It is necessary to do the following. Therefore, it is necessary that at least one of the rolls 9 is always in contact with the surface of the material. On the other hand, in terms of processing rate, it is preferable that the number of contacts is large. This is because it is possible to increase the number of passes per revolution of the cage-type roll group supporting device (processing by one roll is called one pass).
勿論上述の圧延機をレバーシングンミルとして用いて、
左右からの複数パスを可逆的に行う逆転圧延を行っても
よい。Of course, using the above rolling machine as a lever thinning mill,
Reverse rolling may be performed in which a plurality of passes from the left and right are reversibly performed.

平滑化ロール15を使用するのも良い。The rolling method according to the present invention may be carried out not only by carrying out the working portion with a pair of roll groups, but also by carrying out a plurality of rolling mills in tandem. That is, FIG. 5 shows a state where the rolling mills S 1 and S 2 using the basket type roll group and the lower roll are installed in two sets of tandems, but it is effective in terms of more efficient material processing. . Further, in this case, it is also effective to make the directions of rotation of the cage-type supporting devices 8 having the small-diameter rolls 9 of the plurality of rolling mills mutually opposite to each other so as to equalize the directions of the plastic flow of the material. Further, in order to uniformize the slight traces of roll processing generated in the traveling direction of the plate material by the rolls 9 of the basket type roll group, the surface smoothing roll 15 may be used in the final stage of the rolling apparatus.
尚、上記詳細説明は板材を素材の長尺材の例として記述
しているが、勿論素材としては板状のものに限定するも
のではなく、棒状あるいは角状の素材であっても問題が
ない事は言うまでもない。In the above detailed description, the plate material is described as an example of a long material, but of course the material is not limited to a plate-shaped material, and there is no problem if it is a rod-shaped or square-shaped material. Not to mention the matter.

圧延を行った。An embodiment of the present invention will be described below with reference to FIG. The diameter of the lower roll 6 in the widthwise center is 500 mm, the diameter of each roll 9 attached to the basket type roll group is 10 mm, and the diameter of the rolling surface of the roll 9 is 500 mm on the outer periphery of the basket type roll group.
Then, the apparatus as shown in FIG. 1 was constructed, and widthwise rolling was performed using a plate material as an example.
板材の諸元は次の通りである。The specifications of the plate material are as follows.
素材板厚 ti＝0.5mm 素材板幅 wi＝50mm この素材を元にクロス圧延を上記方法で行ったところ、
次の様な結果が得られた。Material plate thickness ti = 0.5mm Material plate width wi = 50mm When this material was cross-rolled by the above method,
The following results were obtained.
製品板厚 to＝0.3mm 製品板幅 wo＝81mm 従ってこの場合の長手方向の伸びは2.9％であり、幅方
向の伸びは62％となった。即ち幅方向の伸びに対する長
手方向の伸びの比率は4.6％であり、ほぼ幅方向圧延が
達成されている事が分かる。Product plate thickness to = 0.3mm Product plate width wo = 81mm Therefore, in this case, the elongation in the longitudinal direction was 2.9% and the elongation in the width direction was 62%. That is, the ratio of the elongation in the longitudinal direction to the elongation in the transverse direction is 4.6%, which shows that the rolling in the transverse direction is almost achieved.

材料のコストを引き下げる事が出来る。The present invention is a method and an apparatus that makes it possible to perform rolling processing extremely efficiently when performing widthwise rolling as described above, and particularly for rolling processing of difficult-to-roll materials that cannot be achieved by unidirectional rolling. By combining the longitudinal rolling and the widthwise rolling according to the present invention, there is an effect that the rolling structure can be controlled more efficiently. Moreover, since the rolling process is performed continuously, it is possible to automate and systemize the rolling process very easily, and it is possible to reduce the cost of the material that requires this type of process.
