Description
【０００１】[0001]
本考案は、削岩用カッタ−のチップに関し、さらに詳しくは、岩盤を削岩する ときに使用される削岩用カッタ−の外周に設けられた削岩用カッタ−のチップの 改良に関する。 The present invention relates to a chip for a rock drilling cutter, and more particularly, to an improvement of a chip for a rock drilling cutter provided on the outer periphery of a rock drilling cutter used when rock drilling rock.
【０００２】[0002]
従来、この種の削岩用カッタ−のチップは、図４に示すように、チップ10の削 岩面11を略Ｉ字状に形成したものが使用されていた。 Conventionally, as a tip of this type of rock drilling cutter, as shown in FIG. 4, a rock drilling surface 11 of a tip 10 is formed in a substantially I shape.
【０００３】 そして、岩盤を削岩する場合は、複円錐状の削岩用カッタ−の外側面に、Ｉ字 状の削岩面11を削岩用カッタ−の軸径方向と同方向にして複数のチップ10…を固 定し、該削岩用カッタ−を回転することにより、チップ10の削岩面11で岩盤を削 岩することができるのである。When the rock mass is to be rock-cut, the I-shaped rock-cut surface 11 is formed on the outer surface of the double-cone rock-cutting cutter in the same direction as the axial direction of the rock-cutting cutter. By fixing a plurality of chips 10 and rotating the rock drilling cutter, the rock mass can be rocked by the rock drilling surface 11 of the chip 10.
【０００４】[0004]
しかしながら上記従来の削岩用カッタ−のチップ10は、長時間岩盤を削岩する とチップ10の削岩面11の両端側より磨耗し、特に削岩用カッタ−の外側の削岩面 11の磨耗が激しくこのためチップ12が傷ついたり、割れたりするという問題があ った。 However, the tip 10 of the above conventional rock drilling cutter is worn from both ends of the rock drilling surface 11 of the tip 10 when the rock is rock drilled for a long time, and especially the rock drilling surface 11 outside the rock drilling cutter There was a problem that the tip 12 was damaged or cracked due to the excessive wear.
【０００５】 また、削岩用カッタ−のチップ12が傷ついたり、割れたりすることによりその つど削岩用カッタ−のチップ12を取り替えなければならずコストがかかるという 欠点があった。Further, there is a drawback in that the tip 12 of the rock drilling cutter has to be replaced each time the tip 12 of the rock drilling cutter is damaged or cracked, resulting in a high cost.
【０００６】 そこで、本考案は上記問題点に鑑みて考案されたもので、岩盤を長時間削岩し ても、磨耗により傷付いたり割れたりすることがなく、しかもコストのかからな い削岩用カッタ−のチップを提供することを課題とする。Therefore, the present invention has been devised in view of the above-mentioned problems, and even if the rock mass is rock-cut for a long time, it is not damaged or cracked due to abrasion, and the rock-cutting is inexpensive. An object is to provide a chip for a cutting cutter.
【０００７】[0007]
本考案のこのような課題を解決するための手段は、岩盤等を削岩するのに使用 される削岩用カッタ−の外周面に設けられ、且つ先細状に形成された先端に略矩 形状の削岩面の設けられた削岩用カッタ−のチップにおいて、チップ本体１の削 岩面４の一端側を長手方向と交差する方向に膨出してなることにある。 Means for solving such a problem of the present invention is provided on the outer peripheral surface of a rock drilling cutter used for rock drilling, etc., and has a substantially rectangular shape at a tip formed in a tapered shape. In the tip of the rock drilling cutter having the rock drilling surface, the one end side of the rock drilling surface 4 of the chip body 1 is bulged in the direction intersecting the longitudinal direction.
【０００８】[0008]
本考案の削岩用カッタ−のチップを用いて岩盤を削岩する場合は、削岩用カッ タ−を回転し、該削岩用カッタ−の外周に設けられたチップ本体１…の削岩面４ を岩盤等に当接して削岩する。これにより当接した削岩面４で岩盤等を削岩する ことができるのである。 When rock mass is rock-cut using the chip of the rock drilling cutter of the present invention, the rock drilling cutter is rotated, and the rock cutting of the chip body 1 provided on the outer periphery of the rock drilling cutter. Face 4 is brought into contact with a bedrock etc. and rock is removed. This allows rock mass to be rock-cut with the rock-cut surface 4 in contact.
【０００９】 この際、該チップ本体１の削岩面４の一端側を長手方向と交差する方向に膨出 しているので、岩盤の削岩による削岩面４の磨耗が少ない。At this time, one end side of the rock cutting surface 4 of the chip body 1 swells in a direction intersecting the longitudinal direction, so that the rock cutting surface 4 is less worn by rock cutting of the bedrock.
【００１０】 従って、岩盤削岩中にチップ本体１の削岩面４が傷ついたり又は割れたりする ことがないのである。Therefore, the rock cutting surface 4 of the chip body 1 is not damaged or cracked during rock cutting.
【００１１】[0011]
以下、本考案の実施例を図面に従って説明する。 図１〜２において、１…燃結タングステン，コバルト（ＷＣ−ＣＯ）超硬合金 性のチップで、円柱状の取付部２と、該取付部２の上方に設けられた削岩部３と により構成されている。 Embodiments of the present invention will be described below with reference to the drawings. 1 and 2, 1 ... Burned tungsten, cobalt (WC-CO) cemented carbide tip, which is composed of a cylindrical mounting portion 2 and a rock drilling portion 3 provided above the mounting portion 2. Has been done.
【００１２】 そして、該チップ本体１の削岩部３は、先端に略Ｔ字状の削岩面４が形成され 、Ｔ字の水平部分4a及び垂直部分4bの側面よりそれぞれ削岩部３の外周に沿って 傾斜面５…が形成されている。The rock drilling portion 3 of the chip body 1 has a substantially T-shaped rock drilling surface 4 formed at the tip thereof, and the rock cutting portion 3 is formed from the side surfaces of the T-shaped horizontal portion 4a and vertical portion 4b to the outer periphery of the rock drilling portion 3, respectively. .. are formed along the inclined surface.
【００１３】 ６…は外周面6aに複数の前記チップ本体１…をＴ字の水平部分4aを外方向にし て、所定間隔で周設した略円錐状の削岩用カッタ−で、レグ７に回転自在に軸支 している。Denoted at 6 is a substantially cone-shaped rock drilling cutter having a plurality of the chip bodies 1 provided on the outer peripheral surface 6a and having a T-shaped horizontal portion 4a directed outward, and provided on the leg 7.
