１が合わせられて第５図の様に積層される。 Next, the operation will be explained. If the number of slots to be provided in the segment core is an odd number and the number of core bolt holes is two, segment core X7 is provided with half of the slot 2 at both ends of the segment, and segment Y8 is provided with a complete slot 2 at both ends of the segment. Two types are produced. Also, 2
The core bolt holes are at an angle of θ/2 (however,
θ: Segment angle, the number of segment divisions is N
They are placed 360°/N) apart. Therefore, the core bolt hole P9 and the core bolt hole Q10 are separated by an angle θ/2, and the core bolt hole R11 and the core bolt hole S12 are also separated by an angle θ/2. Segment core X7 and segment core Y8 have core bolt hole P9 and core bolt hole R12 aligned, and core bolt hole Q10 and core bolt hole S1.
1 are combined and stacked as shown in FIG.
従来のセグメントコアは以上のように構成され

Conventional segment cores are constructed as described above, so two types of core shapes are required, which poses problems such as an increase in the number of extraction tools and an increase in the number of setup changes for the extraction process. The drawbacks were that it took a long time and the tool costs were high.
この発明は上記のような問題点を解消するため
になされたもので、１つの形状のセグメントコア
のみでコアを形成できることを目的としている。 This invention was made in order to solve the above-mentioned problems, and aims to form a core using only segment cores of one shape.
この発明に係るセグメントコアは、コアボルト

である。
The segment core according to the present invention has four core bolt holes, and in the four core bolt holes A to D, A and C form an angle of θ/2 degrees, B and D form an angle of θ/2 degrees, and furthermore, A and C form an angle of θ/2 degrees. B is (slot pitch angle) ×
(n+0.5) Also, C and D form the same angle of (slot pitch angle)×(n+0.5).
この発明における４つのコアボルト穴はそのう

Using two of the four core bolt holes in this invention produces the same effect as creating two types of segment cores by shifting the slot pitch by half.
以下この発明の一実施例を図について説明す

An embodiment of the present invention will be described below with reference to the drawings. In Figure 1, 1 is the segment core, 2 is the slot, 3 is the core bolt hole A, 4 is the core bolt hole B, 5 is the core bolt hole C, and 6 is the core bolt hole D.
It is.
次に動作について説明する。コアボルト穴は順
次コアボルト穴Ａ３とコアボルト穴Ｃ５及びコア
ボルト穴Ｂ４とコアボルト穴Ｄ６が重ねられる。 Next, the operation will be explained. As for the core bolt holes, the core bolt hole A3 and the core bolt hole C5 are overlapped, and the core bolt hole B4 and the core bolt hole D6 are overlapped in this order.
そして、これらのコアボルト穴のピツチは互い
にスロツトピツチ角の半分だけずれているので、
第２図に示される様に積層後のスロツト位置は同
じ所に揃えることができる。 And since the pitches of these core bolt holes are offset from each other by half the slot pitch angle,
As shown in FIG. 2, the slot positions after stacking can be aligned at the same location.
