DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a method for manufacturing a radial core suitable for T(?) adhesive conductors and ship reactors.

The iron core It'd 2 +-1'' is composed of a yoke 6 and a yoke 6 which does not form a sinter.1.

By the way, the shape of each iron block 2a + 2b, 2c, etc. constituting the conventional 1, core 4] 2 is not shown in (2. Nidogi: ] Iwa is layered with arbitrary 19-2 pieces.

However, the core legs 2 are shaped like this), ),;zu4)c and 1':.

Therefore, while the pair of block iron cores 2u, 2b, 2c, 111, a part of the magnetic flux passing through lIj,i! protrudes from the axillary surface of each block i,, l, and the core comrades (,te,
As shown by arrow A? :, I'l meeting, ・(Press-fit from the plane side which is the stacking direction of the plate (2). As a result, a test current due to the magnetic flux is generated 7, and the iron core leg 2 It is necessary to add J;'i to the ``Bay use'' of ``J;'i''. Because there is a shallow part in 1st r ifi'i of 91, shinsusaku 2, the space factor of I + ri cannot be avoided. .

For this reason, instead of forming the iron core legs by intersecting iron core elements with different numbers of grains of %1 in one force direction as described above (two cross sections are circles) [3 < core) is used. It became like 1-. There is a method in which two ``A9 copper plates with different widths are formed radially [circular shape with two distributions f?f] with the cores 1pl and L2 having circular cross-sections. The thin steel plates are arranged radially and formed into a circular shape.Furthermore, by forming the thin steel plates, the laminated ends of each auxiliary plate are aligned with the outer periphery.

Conventionally, when manufacturing a radial iron core such as 1tl-' for the front and 11 for the L-1ζ, a circle was divided equally into 11 blocks, each of which was divided into 2M layers separately, and each block was bonded with 2 layers of epoxy resin, etc. Shape it into a shape.・Then, each block is assembled and fired to make a radial core.

If the height direction dimension is not accurately controlled in the case where a large number of f+c4 cages are arranged and all the magnetic cores are 7'tt℃, the tightening force will not be uniform and vibration noise B will occur more often. Because of this, extra work had to be done to make the insulation spacers parallel to each other by machining after placing them on the radial core.

[Objective of the Invention] The present invention has been made in view of the above points, and its purpose C1 is to form a radial core into a block in one minute (without molding), and to machine it after molding. To provide a method for manufacturing a radial core with high precision without preserving machining.

[Summary of the invention]

In order to achieve the object of the present invention-1 above, thin steel plates are laminated radially in a laminated mold to form a laminate, and while this laminate is folded and straightened with a parallel plate C2, synthetic resin etc. A method for manufacturing a radial core in which an adhesive is contained and integrally formed, and a radial core is formed by laminating plates into a laminate in a laminated mold, and a ceramic-cut insulating gap is placed on one side of the structure. Place the 1% piece flj, t, and fold and straighten the 1'l'^ piece between the insulation using an XF row board, impregnating it with an adhesive such as synthetic resin and integrally molding it (radial Φ) , l','i to the manufacturing method of the heart.
