ヤモンドセグメント型ブレードのセグメントチップに関
する。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a segment tip of a diamond segment type blade used for cutting and drilling hard materials such as stone, concrete, blocks, bricks, tiles, and tiles.
ダイヤモンドセグメント型ブレードにおいて、セグメン
トチップが平坦、均一に摩耗することは切断の真直性を
維持するために特に重要である。In diamond segment type blades, flat, even wear of the segment tip is especially important to maintain straightness of the cut.
ところが、ダイヤモンドブレードによる切断作業時にお
いて、セグメントの周縁部の方が中央部より大きい切断
衝撃負荷を受け、周縁部の方が中 。However, when cutting with a diamond blade, the periphery of the segment receives a larger cutting impact load than the center, and the periphery receives a larger cutting impact load than the center.
央平坦部より先に摩耗し易く、その断面形状が丸い形状
となる。The center flat part tends to wear out first, and its cross-sectional shape becomes round.

。Conventionally, as a countermeasure to this problem, the hardness and density distribution of the abrasive material that forms the segments is changed, or the segments are formed into a sandwich shape using a bonding agent whose hardness varies depending on the position. Those aiming at equalizing the wear are disclosed in Japanese Utility Model Publication No. 53-13991, Japanese Utility Model Application Publication No. 47-6491, Japanese Utility Model Application Publication No. 57-83372, and Japanese Utility Model Publication No. 60-12694.

して摩耗速度が早く、工具の寿命が低下するばかりでは
なく、両サイドで高低ができたり、極端に両サイドが立
った場合、サイドエツジが破損することがある。However, the segments described in the above publication have a low-density abrasive material or a soft member in the center, and in addition, the segments are formed of layers with different properties, so the overall wear rate is high and the tool has a long lifespan. Not only will this decrease, but if both sides become uneven, or if both sides stand up too much, the side edges may be damaged.
これらの現象に加えて、ダイヤモンドブレードによる切
削において切粉排出に必要なりリアランスが、側面の摩
耗によって消滅し、切断作業が不可能となる問題がある
。In addition to these phenomena, when cutting with a diamond blade, there is a problem that the clearance required for ejecting chips disappears due to wear of the side surface, making cutting work impossible.
ところが、ダイヤモンドセグメントチップにおける側面
摩耗に対する対策は従来、何等採られていない。However, conventionally, no measures have been taken to prevent side wear of diamond segment tips.
本発明は、ダイヤモンドブレードのセグメントチップの
両側部表面を耐摩耗性とすることによって切削作業中の
切粉による側面摩耗を防止することによって、クリアラ
ンスを確保して上記目的を達成したものである。The present invention achieves the above object by ensuring clearance by making the surfaces of both sides of the segment tip of a diamond blade wear-resistant to prevent side wear caused by chips during cutting operations.
両側部表面を耐摩耗性とするための具体的な手段として
、第１図に示すように、基体１の外周部に、基体１とク
リアランス２を有して形成されたダイヤモンドセグメン
トチップ３の両側面に耐摩耗性粒子４がダイヤモンド砥
材５と共に表面に露出した状態で埋め込まれた構造にす
る。As a specific means for making the surfaces of both sides wear-resistant, as shown in FIG. The structure is such that wear-resistant particles 4 and diamond abrasive material 5 are embedded in the surface in a state where they are exposed on the surface.
耐摩耗性粒子４としてはＷ２２Ｃ、ＷＣ、Ｗ２Ｃ、ＷＣ
、ＴｉＣ。Wear-resistant particles 4 include W22C, WC, W2C, and WC.
, TiC.
ＴｉＮ、 Ａｌ２Ｏ３，ＳｉＣもしくはセラミックス
粒を用いる。同耐摩耗性粒子４の径は、使用する砥材の
サイズで異なるが、例えば砥材であるダイヤモンド粒子
５０粒径が４０メツシユの場合は３００ｐ径のＷ ２
ＣｒＬを用いることができる。TiN, Al2O3, SiC or ceramic grains are used. The diameter of the wear-resistant particles 4 varies depending on the size of the abrasive used, but for example, if the diameter of 50 diamond particles used as the abrasive is 40 mesh, the diameter of the wear-resistant particles 4 is 300p.
CrL can be used.
第２図に示すように、耐摩耗性粒子４ａが小さすぎると
、側面のドレッシングの際に、砥材５の粒径の１５〜５
０％位の表面厚さの結合剤６と共に削り落とされてしま
う。このためドレッシング後も耐摩耗性材料を残留させ
るためには、少なくともダイヤモンド砥材５とほぼ同粒
径が必要である。As shown in FIG. 2, if the wear-resistant particles 4a are too small, they may be 15 to 5 times smaller than the particle size of the abrasive material 5 during side dressing.
It is scraped off together with the binder 6, which has a surface thickness of about 0%. Therefore, in order for the wear-resistant material to remain after dressing, it is necessary that the grain size is at least approximately the same as that of the diamond abrasive material 5.
また、第３図に示すように、逆に耐摩耗性粒子４ｂが大
きすぎると、ドレッシング後、砥材５の突出高さより耐
摩耗性粒子の突出高さが高くなり、これが切れ味に対し
てブレーキとして働くため不適当である。Moreover, as shown in FIG. 3, if the wear-resistant particles 4b are too large, the protruding height of the wear-resistant particles will be higher than the protruding height of the abrasive material 5 after dressing, and this will cause a brake on the sharpness. Unsuitable for working as a.
また、耐摩耗性粒子４を埋め込む深さは、ダイヤモンド
砥材５の粒径までとし、側面の表面に必ず耐摩耗性粒子
４が出現している必要がある。チップ内に深く埋まり込
むと、砥材５による切れ味に対する抵抗となる。Further, the depth at which the wear-resistant particles 4 are embedded must be up to the particle size of the diamond abrasive material 5, and the wear-resistant particles 4 must appear on the side surfaces. If it is deeply embedded in the chip, it will resist the sharpness of the abrasive material 5.
上記耐摩耗性粒子４の分散量は、１個の耐摩耗性粒子の
摩耗防御ゾーン域の大きさによって決定される。The amount of dispersion of the wear-resistant particles 4 is determined by the size of the wear protection zone of one wear-resistant particle.
実験によると、１個の耐摩耗性粒子４による摩耗防御ゾ
ーンは第４図に示すとおり、ブレードの回転方向の後方
に向かって、耐摩耗性粒子の粒径りの１０〜３０倍であ

３００１ｓの場合、側面全体を防御するために必要な耐
摩耗性粒子４の量は、側面の全面積に対し、３〜２０％
の面接率を占めることが最適である。According to experiments, the wear protection zone by one wear-resistant particle 4 is 10 to 30 times the particle diameter of the wear-resistant particle toward the rear in the rotating direction of the blade, as shown in FIG. has been confirmed. Therefore, when the wear-resistant particle diameter is 3001s, the amount of wear-resistant particles 4 necessary to protect the entire side surface is 3 to 20% of the total area of the side surface.
It is optimal that the interview rate be
この分布率が３％よりも少ないと、側面摩耗の防止効果
が少なく、また２０％よりも多いと、砥材の切れ味を低
下させることになる。If this distribution ratio is less than 3%, the effect of preventing side wear will be small, and if it is more than 20%, the sharpness of the abrasive will be reduced.
さらに、耐摩耗性粒子４の形状として球状、立方体、板
状等、任意の形状を採り得る。Furthermore, the shape of the wear-resistant particles 4 may be any shape such as spherical, cubic, or plate-like.

る方法等がある。As a method for distributing wear-resistant particles on the side surface of the segment chip, there is a method in which the wear-resistant particles are adhered to a punch for the chip side surface, and the space between them is filled with diamond particles and metal powder, and then sintered. A method of charging only one layer of powder containing wear-resistant particles, filling it with diamond and metal powder, and then charging a layer of powder containing wear-resistant particles on top of that and simultaneously sintering. There are methods such as making a green compact containing diamonds, applying an adhesive to the sides, pasting wear-resistant particles, and sintering it.
また、本発明による側面強化セグメントチップは、上記
従来の粒度、密度等の分布調整と併用することも勿論可
能である。Furthermore, it is of course possible to use the side-reinforced segment chip according to the present invention in combination with the above-mentioned conventional distribution adjustment of particle size, density, etc.
