本発明は磁性材でもつて形成するラミネート用コア−
の製造方法に関するもので、同コア−が精度よく容易に
製造できるようにしたものである。[Detailed Description of the Invention] The present invention provides a laminating core made of a magnetic material.
The present invention relates to a manufacturing method for the core, which enables the core to be easily manufactured with high precision.
この種のコア−を形成する場合には一般に第１図のよ

断ということになり、その固定面積の関係から、良好な
固定がおこなえず、精度の良い切断はおこなえない。When forming this kind of core, generally a magnetic material block 1 as shown in FIG. As shown in FIG. 2 or 3, the cores shown in 3 in FIG. 1 are cut one by one or with a plurality of cutters using a diamond cutter or the like while the base plate 4 is fixed to a base plate 4 made of glass or the like. I try to get multiple cores at the same time. However, both in the case of Fig. 2 and the case of Fig. 3, the magnetic material block 2 is cut while being fixed to the base plate 4, and due to the fixing area, good fixing cannot be achieved, resulting in poor precision. A good cut cannot be made.
また破損しやすい等の欠点がある。 本発明はこのよう
な欠点を除去したもので以下第４図〜第６図の実施例に
より説明する。It also has drawbacks such as being easily damaged. The present invention eliminates these drawbacks and will be described below with reference to embodiments shown in FIGS. 4 to 6.

つてから、コアー１２′（１２１′〜１２５’）のみ取
り出すようにすることによつてラミネートコア−を形成
できるようにしたものである。In this case, the molding agent consists of a resin agent and glass beads, and the dots in the figure correspond to the glass beads. FIG. 5 shows a state in which the sheet has been cut to a certain size, and FIG. 6 shows a state in which a part of the cut sheet is divided into two. That is, the present invention provides the magnetic material block 12 with arbitrary dimensions (thickness).
In order to obtain a core like 3 in the figure, molding agent 13
It is possible to form a laminate core by first molding the mold, cutting it to size in that state, and then taking out only the core 12'(121' to 125'). .
ここでモールド剤１３としては樹脂材のみでもよいが
、この場合には樹脂自身が切断時のダンパーになつてし
まい良好な切断がおこなえない。Here, only a resin material may be used as the molding agent 13, but in this case, the resin itself acts as a damper during cutting, making it impossible to perform good cutting.
またガラス剤をモールド剤として使用した場合、樹脂剤
に比べ粘着力が劣るためやはり破損しやすい。そこで本
発明では樹脂剤にガラスビーズを混入させて樹脂剤およ
びガラス剤の欠点を補うようにしている。Furthermore, when a glass agent is used as a molding agent, it is more likely to be damaged because it has inferior adhesive strength compared to a resin agent. Therefore, in the present invention, glass beads are mixed into the resin agent to compensate for the drawbacks of the resin agent and the glass agent.
なお粘着度は混合比によつて変ることはいうまでもない
。第４図のようにモールド剤１３でもつて磁性材ブロッ
ク１２をモールドした状態で第５図のように定寸切断し
た後のコアー１２″の取り出しは第６図のように割つて
いつてコアー１２″のみを取り出すようにしても、ある
いはモールド剤部１３″を溶かす液の中に入れてモール
ド剤部１３″を溶かしコアー１２″のみを取り出すよう
にしてもよい。It goes without saying that the tackiness varies depending on the mixing ratio. After molding the magnetic material block 12 with molding agent 13 as shown in FIG. 4 and cutting it to a fixed size as shown in FIG. 5, the core 12'' can be taken out by splitting it as shown in FIG. Alternatively, only the core 12'' may be taken out by placing the molding agent part 13'' in a solution to dissolve it.
またモールド剤１３にはガラスビーズを混入させている
ために切断時に使用するカッタおよび切断部を冷却する
ための冷却液の吸収が容易であり、しかも切断の方向性
での強度化もなく一定の切断力で切断ができ、切断精度
向上に寄与できる。In addition, since glass beads are mixed in the molding agent 13, it is easy to absorb the cutter used during cutting and the cooling liquid used to cool the cutting part, and there is no increase in strength depending on the cutting direction. Cutting can be done using cutting force, contributing to improved cutting accuracy.
さらに複数個同時にモールドしておくことにより、量産
化が有利である。Furthermore, mass production is advantageous by molding a plurality of pieces at the same time.
磁性材ブロックの形状（ラミネ−トコアーの形状）にか
かわりなく容易に製造できる。以上の説明から明らかな
ように本発明によればガラスビーズを混入させたモール
ド材中にコアーを入れておいて切断するようにしている
ため、切断時に方向規制を良好に行うことができ、正確
な切断を行なうことができる。It can be easily manufactured regardless of the shape of the magnetic material block (the shape of the laminate core). As is clear from the above explanation, according to the present invention, since the core is inserted into the mold material mixed with glass beads before cutting, the direction can be well controlled during cutting, and the cutting can be performed accurately. You can make precise cuts.
また切断時のコアーの破損も防止できる。It also prevents damage to the core during cutting.
