Description
【考案の詳細な説明】 〔産業上の利用分野〕 この考案は、岩石や大理石などの切断に用いられるワイ
ヤソーに関するものである。DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a wire saw used for cutting rocks, marble, and the like.
上記ワイヤソーの従来技術として、第４図に示すよう
に、ワイヤ１に樹脂層２を被覆し、その樹脂層２を介し
て所定間隔で多数の円環状スリーブ３を固定し、このス
リーブ３の外周面に、ダイヤモンドや立方晶窒化ホウ素
（ＣＢＮ）などの硬質砥粒層４を固着して切断刃を形成
したものがある。As a conventional technique of the wire saw, as shown in FIG. 4, a wire 1 is covered with a resin layer 2 and a number of annular sleeves 3 are fixed at predetermined intervals via the resin layer 2, and the outer circumference of the sleeve 3 is fixed. There is one in which a hard abrasive grain layer 4 such as diamond or cubic boron nitride (CBN) is fixed to the surface to form a cutting blade.
上記の樹脂層２は、スリーブ３とワイヤ１とを固着し
て、スリーブ３の回転やピッチずれを防止すると共に、
ワイヤ１を切屑等から保護する役割をもち、通常ワイヤ
１の周面全体に被覆される。The resin layer 2 fixes the sleeve 3 and the wire 1 to each other to prevent rotation of the sleeve 3 and displacement of the pitch, and
It has a role of protecting the wire 1 from chips and the like, and is usually coated on the entire peripheral surface of the wire 1.
ところが、上記のごとき構造のワイヤソーにおいては、
スリーブ３と樹脂層２の固着が樹脂の接着力だけによっ
ているために、両者間の連結が十分に得られず、切断中
スリーブ３と樹脂層２との固着が外れて、スリーブ３が
空回りし、ワイヤ１とこすり合ってワイヤ１を破断させ
る事故を引き起こすことがある。However, in the wire saw having the above structure,
Since the adhesion between the sleeve 3 and the resin layer 2 is solely due to the adhesive force of the resin, the connection between the two is not sufficiently obtained, and during cutting, the adhesion between the sleeve 3 and the resin layer 2 is released, and the sleeve 3 runs idle. , The wire 1 may be rubbed against each other to cause an accident of breaking the wire 1.
この考案は、上記の問題を解決し、スリーブと樹脂層間
の確実な固着が得られるワイヤソーを提供することを目
的としている。It is an object of the present invention to provide a wire saw that solves the above-mentioned problems and that can reliably secure the sleeve and the resin layer.
上記の問題を解決するため、この考案は、円環状スリー
ブに、そのスリーブから樹脂層に向かってワイヤの長さ
方向に突出する係止部を設けたものである。In order to solve the above problems, the present invention provides an annular sleeve with a locking portion that projects from the sleeve toward the resin layer in the length direction of the wire.
上記のように構成される手段においては、円環状スリー
ブから突出した係止部が樹脂層に入り込むことにより、
スリーブの回転が止められる。In the means configured as described above, the locking portion protruding from the annular sleeve enters the resin layer,
The rotation of the sleeve is stopped.
これに対して、強度の弱い樹脂層からスリーブに向かっ
て係止部を突出させるようにすると、係止部の強度が小
さくなり、大きな回り止め力が得られない。また、係止
部をスリーブからワイヤの径方向に突出させるようにし
た場合は、スリーブの内周面とワイヤの間の間隔が小さ
いために、係止部の突出量を大きくできず、このため回
り止め効果が期待できず、成形も難しい。On the other hand, if the locking portion is made to project from the resin layer having low strength toward the sleeve, the strength of the locking portion becomes small and a large detent force cannot be obtained. Also, when the locking portion is made to project in the radial direction of the wire from the sleeve, the distance between the inner peripheral surface of the sleeve and the wire is small, and therefore the amount of projection of the locking portion cannot be increased. The anti-rotation effect cannot be expected and molding is difficult.
以下、この考案の実施例を添付図面に基づいて説明す
る。An embodiment of the present invention will be described below with reference to the accompanying drawings.
第１図及び第２図に示す実施例は、円環状スリーブ３の
側面に、それぞれワイヤ１の長さ方向に突出する係止部
６、７を設けたもので、上記係止部６、７が樹脂層２内
部に入り込んで固着されることにより、スリーブ３の回
転方向の動きが抑えられ、空回りが防止される。In the embodiment shown in FIG. 1 and FIG. 2, locking portions 6 and 7 projecting in the length direction of the wire 1 are provided on the side surfaces of the annular sleeve 3, respectively. By entering the inside of the resin layer 2 and fixing it, the movement of the sleeve 3 in the rotation direction is suppressed, and idling is prevented.
また、第３図は他の実施例を示し、この例のように、硬

の回り止めとあいまって、砥粒層４のワイヤ１に対する
位置ずれが極小に抑えられ、安定した刃具寿命が得られ
る。Further, FIG. 3 shows another embodiment. As in this example, if the hard abrasive grain layer 4 is provided with the protruding portion 4a so as to be prevented from rotating with respect to the sleeve 3, the sleeve 3 with respect to the wire 1 is prevented.
Together with the rotation stopper, the positional deviation of the abrasive layer 4 with respect to the wire 1 can be suppressed to a minimum, and a stable cutting tool life can be obtained.
以上説明したように、この考案は、円環状スリーブから
樹脂層に向かって係止部を突出させ、この係止部により

脂層間の固着力が大きくなり、スリーブを確実に樹脂層

ワイヤの不都合が破断が防止されて、バラツキの少ない
安定した刃具寿命を実現することができる。As described above, according to this invention, the locking portion is projected from the annular sleeve toward the resin layer, and the rotation of the sleeve is stopped by this locking portion, so that the fixing force between the sleeve and the resin layer is large. Therefore, the sleeve can be securely fixed to the resin layer. Therefore, the inconvenience of the wire during cutting is prevented from being broken, and a stable cutting tool life with less variation can be realized.
