【発明の詳細な説明】
［産業上の利用分野］
本発明は、板材の幅圧下方法及び装置に関するものであ
る。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method and apparatus for reducing the width of a plate material.
［従来の技術］
一般に、金属板材の圧延は粗圧延と仕上圧延との二段階
の工程で行われる。而して、仕上圧延では板材を所定の
板厚に成形しなければならないが、通常、ロール撓みに
より板材の端部にはエツジドロップが生じ歩留りの低下
をもたらす。そこで、仕上圧延工程の途中で板材に幅圧
下を掛け、板材の端部にドツグボーンを形成して、上記
エツジドロップの発生を防止するようにしている。[Prior Art] Generally, rolling of metal sheets is performed in two steps: rough rolling and finish rolling. In finish rolling, the plate must be formed to a predetermined thickness, but edge drops usually occur at the ends of the plate due to roll deflection, resulting in a reduction in yield. Therefore, width reduction is applied to the plate material in the middle of the finish rolling process, and dog bones are formed at the ends of the plate material to prevent the occurrence of the edge drop.
［発明が解決しようとする問題点］
しかしながら、仕上圧延工程では既に板材の板厚は薄く
なっているため、強幅圧下を行うと板材が座屈してしま
う問題があり、従って、強幅圧下を行うことができなか
った。また、粗圧延後、材料の長さは長くなり、ロール
以外の例えば金型による幅圧下は生産効率上、不利であ
った。[Problems to be Solved by the Invention] However, since the thickness of the plate material has already become thinner in the finish rolling process, there is a problem in that the plate material buckles when a strong width reduction is performed. I couldn't do it. Further, after rough rolling, the length of the material becomes long, and width reduction using a tool other than rolls, such as a die, is disadvantageous in terms of production efficiency.
本発明は斯かる実情に鑑み、板材の板厚が薄く長くても
強幅圧下を金型により行うことができるようにしたもの
である。In view of these circumstances, the present invention is designed to enable strong width reduction to be performed using a mold even if the plate material is thin and long.
［問題点を解決するための手段〕
本発明は、帯状の板材をルーズな状態でコイル状に巻取
るコイラー装置と、対向配置した金型を有し該金型を近
接・離反動することにより材料をコイルのまま幅圧下す
る幅圧下装置本体とを備えた構成を有する。[Means for Solving the Problems] The present invention has a coiler device that winds a strip-shaped plate material into a coil in a loose state, and a mold that is disposed facing each other, and moves the molds toward and away from each other. It has a configuration including a width reduction device main body that reduces the width of the material as it is in the form of a coil.
［作 用］
従って、板材はコイル状に巻き取られた状態で幅圧下さ
れる。[Function] Therefore, the width of the plate material is rolled down while being wound into a coil.
［実 施 例］ 以下、図面を参照して本発明の詳細な説明する。[Example] Hereinafter, the present invention will be described in detail with reference to the drawings.

有する。The above-mentioned coiler device 3 is, for example,
It has the same structure as the coiler device disclosed in Japanese Patent Publication No. 52-45304, etc.
Pinch rolls 5, 6 that apply feeding force by sandwiching the material, and a guide plate 7 that guides the plate material l coming out from the pinch rolls 5, 6.
A bending roll 8.9.10 which applies the required bend to the plate material l fed along the guide plate 7, and bending rolls 8,9.
The receiver that receives the plate material 1 bent at 10 to form the coil 2 in a loose state has rolls 11, 12, 13, etc.

。Further, the width reduction device main body 4 includes a mold 14.14 and a mold J, 4.1, which are arranged facing each other so as to face the end surface of the coil 2.
A cylinder 15.15 that moves the cylinders 15.
and a support rod 17.17 which connects the base frames ie and te and receives the reaction force when the base frames are rolled down.

8.9.10.
As it passes through the gap, it receives the necessary bending force and gradually curves. In the first roll of the curved plate material 1, the receiver rests on the roll 11, 12 as shown by the two-dot chain line in FIG. It is transferred onto the rolls 12 and 13, where it becomes the coil 2. At this time, the molds 14 and 14 are positioned so as to lightly touch both width end surfaces of the coil 2, thereby preventing the coil 2 from becoming cylindrical.
前記において、曲げロール８．９．１０の上下方向の位
置調整と受はロール１１．１２．１３の回転速度調整に
よって、コイル２の巻き状態が調整される。In the above, the winding state of the coil 2 is adjusted by adjusting the vertical position of the bending roll 8.9.10 and adjusting the rotational speed of the roll 11.12.13.
上述のようにして受はロール１２．１３上にてコイル２

よって板材１の幅圧下をまとめて行う。As described above, the receiver is placed on the roll 12.13 and the coil 2
is formed, actuate cylinder 15.15 to release mold 1.
4. 14 is moved toward and away from the coil 2 in the width direction, thereby reducing the width of the plate material 1 all at once.
このように、コイル２となった板材ｌに対して幅圧下を
行うので、板材■は座屈強度が向上する。従って、金型
１４．１４にて強幅圧下を掛けることができ、ドツグボ
ーンを大きく作ることかできる。In this way, since the width reduction is performed on the plate l which has become the coil 2, the buckling strength of the plate l is improved. Therefore, it is possible to apply a strong reduction in the mold 14 and 14, and it is possible to make a large dog bone.
