Description of the Related Art Conventionally, as disclosed in Japanese Patent Publication No. 61-22851, a method for manufacturing a wound iron core of this type has a circular or polygonal cross section after winding the core on both side edges or one side edge. It is formed by continuously stacking and winding strip-shaped silicon steel sheets that are cut and formed into a quadratic curve such that

費用が多額にのぼり、材料の歩留まりも悪く、製品コス
トが高くつき、さらに大量生産に不向きであるという課
題があった。Therefore, it is necessary to maintain an accurate quadratic curve when cutting out this type of conventional silicon steel sheet, and it is necessary to cut out the cut in the longitudinal direction into the quadratic curve. Since it was necessary to control the slitter machine with a large-scale NC control device or a computer with a high-level software program, complicated and complicated calculations were required, and a high degree of skill was required for operation, and therefore the device cost was high. There are problems that the cost is high, the yield of materials is low, the product cost is high, and it is not suitable for mass production.

固定し難い等々の欠点があるという問題があった。Further, since a steel sheet having a quadratic cut edge is rolled up in a single layer, there is a deviation from the lower winding layer, and it is difficult to form a perfect circular cross-section after being wound on the core. . Furthermore, since the cross section of the yoke portion adjacent to the coil winding portion is circular, the cross sectional area cannot be large, the utilization efficiency of the steel plate is poor, and the sitting condition on both sides is unstable,
There was a problem that it was difficult to fix it.

顕著な効果を有するに至ったのである。As apparent from the above description, according to the method of the present invention, the hoop material of the silicon steel plate is moved by the electronic control device, and the male and female punching dies are finely moved to linearly move the hoop material. It is possible to accurately and precisely and automatically perform stepwise punching by changing the dimensions and intervals of the notches of the shape, and do not perform finishing on it.
In addition, it is possible to immediately carry out a part of work by sending it to the next core winding process in a streamlined work, and also directly connecting the coil winding process.
You can do it. Moreover, the utilization efficiency of the steel plate is about 13 compared to the conventional one.
