有していた。(Problems to be Solved by the Invention) However, all of these methods have problems in that the devices have complicated mechanisms and the life of the wire drawing tool is short. In addition, it is necessary to temporarily stop the steel plate and draw the wire, which has the disadvantage of poor efficiency.

置を提供しようとするものである。 This invention was made in order to solve the above-mentioned problems, and uses an extremely simple mechanism to efficiently and continuously apply micro-strain uniformly over the entire surface of a steel plate without stopping the steel plate. It is an object of the present invention to provide a method and apparatus for applying strain to a steel plate, which can apply strain to a steel plate with high precision.

ロールと回転可能で平滑な押えロールとで鋼板を
挟圧する。(Means for Solving the Problems) The method of applying strain to a steel plate according to the present invention involves moving a steel plate while applying a tensile force to the steel plate, while rotating a rotatable member having a protrusion extending spirally along the circumferential surface. A steel plate is pressed between a smooth strain roller and a rotatable, smooth presser roll.

なつている。 Further, the straining device for a steel plate of the present invention includes a straining roll that has a plurality of protrusions extending spirally along the circumferential surface and is rotatably supported, and a straining roll that is disposed directly below the straining roll and rotates. It consists of a freely supported smooth presser roll and a device for adjusting the gap or pressing force between the straining roll and the presser roll.
鋼板に引張力を与えるには、たとえば与歪ロー
ルの周速度をペイオフリールの周速度よりも速く
する。 To apply tensile force to the steel plate, for example, the circumferential speed of the straining roll is made faster than the circumferential speed of the payoff reel.

もに押圧力の変動が大きくなり、また85度を超え
ると微小歪による鉄損減少効果が小さくなる。 In the above-mentioned straining roll, the winding direction of the twist of the protrusion may be either left or right, or may be a combination of left and right directions. The cross-sectional shape of the protrusion may be any shape as long as it does not cause unnecessary scratches on the surface of the steel plate, such as a trapezoid, a triangle, a rectangle, or a semicircle. The pitch of the protrusions is preferably about 1 to 20 mm,
If it is less than 1 mm or more than 20 mm, the iron loss will become larger. The pitches of the protrusions may be equally spaced or unevenly spaced. Further, the appropriate twist angle is in the range of 5 to 85 degrees. If it is less than 5 degrees, a large pressing force is required to give a minute strain, and the fluctuation of the pressing force becomes large, and if it exceeds 85 degrees, the effect of reducing iron loss due to minute strains becomes small.

る方法が考えられる。 Furthermore, in the present invention, when this device is incorporated into an existing threading line as a means for moving steel plates, it is more rational to utilize the functions of the existing payoff reel and tension reel installed at the front and rear, respectively. Furthermore, when the present apparatus is used alone, it is possible to use a drive motor or the like to rotate both or one of the straining roll and the presser roll.

起部の形状を転写するようにして微小歪が生じ
る。(Function) When a strain roll having a plurality of protrusions extending spirally along the circumferential surface is rotatably pressed against the steel plate while moving the steel plate, the protrusions of the strain roll bite into the surface of the steel plate. In the portion where the protrusion bites, minute distortion occurs as if the shape of the protrusion is transferred.

さらに、常に突起部が鋼板表面を押圧しているの
で、与歪ロールおよび押えロールを無駆動として
も、鋼板を他の送り装置によつて鋼板を両ロール
間に送り込むことにより、両ロールは回転する。 Since the protrusions of the straining roll extend spirally along the circumferential surface, even if the straining roll is at any rotational position, one of the protrusions always makes point contact with the steel plate surface. It's pressing. Therefore, the pressing reaction force does not fluctuate during the straining operation and remains approximately constant, making it easy to adjust the pressing pressure. Further, since the protrusions make point contact, only a small pressing force is required.
Furthermore, since the protrusions are always pressing the surface of the steel plate, even if the straining roll and presser roll are not driven, the steel plate can be rotated by feeding the steel plate between the two rolls using another feeding device. do.
鋼板に引張力を加えることにより、鋼板は平坦
となり、また押圧力は軽減される。したがつて、
所定の深さ、形状およびピツチの微小変形を、鋼
板全面にわたつて一様にかつ高い精度で与えるこ
とができる。 By applying tensile force to the steel plate, the steel plate becomes flat and the pressing force is reduced. Therefore,
Minute deformation of a predetermined depth, shape, and pitch can be applied uniformly and with high precision over the entire surface of the steel plate.
押えロールは平滑であるため、鋼板はロール軸
方向に沿つて均一に支持される。この結果によつ
ても、鋼板全面にわたつて一様にかつ高い精度で
所要の微小変形を与えることができる。 Since the presser roll is smooth, the steel plate is supported uniformly along the roll axis direction. With this result as well, the required minute deformation can be applied uniformly and with high precision over the entire surface of the steel plate.
さらに、押えロールを与歪ロールの下側に配置
することにより、押えロールの支持機構に鋼性を
もたせることが容易となる。このことによつて
も、鋼板全面にわたつて一様にかつ高い精度で所
要の微小変形を与えることができる。 Furthermore, by arranging the presser roll below the straining roll, it becomes easy to provide the support mechanism of the presser roll with steel properties. This also allows the required minute deformation to be applied uniformly and with high accuracy over the entire surface of the steel plate.
微小変形の深さ、形状およびピツチによつて鉄
損は大きく影響される。したがつて、精密な微小
変形の付与により鉄損は一層低くなる。 Iron loss is greatly affected by the depth, shape, and pitch of minute deformations. Therefore, by applying precise micro-deformation, iron loss is further reduced.

The straining roll itself can be manufactured in advance as a spare part, and the straining roll can be installed and removed extremely easily, and there are no restrictions on the installation location. Further, since the straining roll is rotated to apply minute strain while feeding the steel plate, straining work can be performed continuously. Furthermore, since the pressing force of the strain roll against the steel plate is relatively small, the life of the strain roll is extended.
Moreover, since the required minute deformation can be applied uniformly and with high precision over the entire surface of the steel plate, iron loss can be further reduced.
