価格上昇を招くという欠点がある。 Conventionally, this type of interpol was developed by, for example, Japanese Patent Application Laid-open No.
- A punched steel plate 3 having an intercoil presser 2 as disclosed in Japanese Patent No. 85303 and further shown in FIG.
are laminated and a rivet 4 is passed through them to form an integrated structure. Fixing to the casing is performed by screwing a bolt, which is placed through the casing, into the screw hole 5. However, with Interpol having such a structure, it takes a lot of effort to manufacture the punched steel plates 3 and to stack the punched steel plates 3.
The disadvantage is that it leads to price increases.

本発明は、帯状の強磁性部材を順次折り曲げて
積層し、折り曲げ部分を溶接固定したことを特徴
とするインターポールの製作方法にある。 The present invention resides in a method of manufacturing an interpol, characterized in that band-shaped ferromagnetic members are sequentially bent and laminated, and the bent portions are fixed by welding.
以下本発明を第２図および第３図に示した実施
例を用いて詳細に説明する。 The present invention will be explained in detail below using the embodiment shown in FIGS. 2 and 3.

設けてある。 FIG. 2 is a perspective view showing one embodiment of the interpol of the present invention, and FIG. 3 is a perspective view showing a part of the manufacturing process of the interpol shown in FIG. In FIG. 2, reference numeral 6 denotes a strip-shaped ferromagnetic member, and as shown in FIG. There is an escape hole 8 for this purpose. After the ferromagnetic members 6 are sequentially bent and stacked, relief holes 8 are formed on both end faces.
Place the L fitting 10 for fixing the intercoil, which has a notch 9 corresponding to a semicircular arc, align the escape hole 8 and the notch 9, run the welding beam 11 there, and bend. The parts are welded together and the L fitting 10 is welded to integrate the whole. The L fitting 10 corresponds to the intercoil presser 2 shown in FIG. Note that 12 is a screw hole for fixing the thus constructed interpol 13 to the casing, and is provided perpendicular to the welding direction.

する鋼板間が確実に接合ができる。 According to the embodiment of the present invention described above, since the strip-shaped ferromagnetic members 6 are sequentially bent and laminated, the labor of stacking and aligning them one by one as in the conventional method is eliminated, and the product can be made at low cost. can. In addition, since the escape hole 8 is drilled in the part corresponding to the bending part, bending is easy, the bending position is accurately determined, and even if it is a single plate, adjacent steel plates are reliably joined. I can do it.
以上説明したように、本発明によれば、積層し
