Description of the Related Art Conventionally known tip saws are provided with means for inserting a carbide tip obliquely at equal intervals into a circumferential surface of the tip saw. Until the end, the tooth part of the mountain part was deeply bitten and covered and fixed. Therefore, when cutting, the chips of the object to be cut collide with the tooth base due to the lead angle formed by the rake face of the chip cutting edge, and the chip is not discharged smoothly, and the cutting action of the chip cutting edge to the object to be cut is ensured. In addition, it was not performed well, and the chip was gradually worn out due to collision of the chip with the tooth base.

In FIG. 9, the contact of the tip of the disc body which rotates with respect to the edge of the tip body is between a and c. It comes to tear between. The torn chips tend to flow in the horizontal direction of the disc along the rake face of the blade, but immediately before that, they are pressed by the rotational force of the disc and collide with the front edge of the tooth base to apply a load. This has resulted in abrasion of the pedestal portion on which the tip body fits during long-term use, and the strength of the mounting portion of the tip body is gradually reduced.

が、後方の次のチップ７' が回転してくるから、実際に
はａ−ｂ間の刃部で切り裂くようになる。When the article is used, the contact of the tip body on the periphery of the rotating disc body with the cutting object A such as shrubs or vegetation is caused by the fact that the blade portion of the tip body 7 in FIG. However, since the next chip 7 'at the rear rotates, the chip 7' is actually torn at the blade portion between a and b.

平面方向に流れて排出するようになる。In FIG. 6, the chips of the cut object tend to flow out in the horizontal plane direction of the disk along the rake face of the rake angle α of the blade portion, but are pushed by the rotational force of the disk. The horizontal surface of the disk body, which is the side surface of the tooth part, without colliding with the leading edge of the valley, along the rake face and sliding surface of the tip body that has emerged obliquely at the corner of the tooth part. It flows in the direction and becomes discharged.

体の取付け強度は、図７に示すように接線方向への力Ｐ
1 と円盤体を押し返す円盤体の中心方向へのＰ2 とその
合成力Ｐに抵抗できる強度が必要となる。As shown in FIG. 7, the mounting strength of each chip body against the impact force of the chips on the workpiece is a force P in the tangential direction as shown in FIG.
1 and P 2 and the resistance can strength to the combined force P toward the center of the disk body to push back the disk body is required.
【０００９】この合成力Ｐの作用は、チップ体の取付け
方向へ押し込むように作用するものであるから、問題は
ない。接線方向への力Ｐ1 は、チップ体の逃げ面際まで
歯台部で支持しているから、抵抗力は十分発揮する。There is no problem because the action of the resultant force P acts to push the tip body in the mounting direction. The force P 1 in the tangential direction is supported by the tooth base portion up to the flank of the tip body, so that the resistance force is sufficiently exerted.
【００１０】円盤体中心方向への力Ｐ2 の作用に抗する
強度は、回転中の各歯台部のチップ体にかかる作用力に
よって、各チップ体に分散される。[0010] strength to resist the action of the force P 2 of the disk body center direction by the action force applied to the tip of each tooth base portion during rotation, it is distributed to each chip body.
【００１１】チップ体の各歯台部への取付け巾Ｗに比例

The chip bodies 7 and 7 ′ are fitted into the concave grooves provided at equal intervals (inclination of degrees). The blade portions of the tip bodies 7 and 7 ′ are composed of a front rake face 8 and a rear flank 9 in the rotation direction of the disk body 1 . α indicates the rake angle of the rake face 8 (FIG. 6), and β indicates the rake angle of the flank 9 (FIG. 4).

用することができるのである。According to the present invention having such a structure, chips are slid from the rake face of the blade portion of the chip body to the slidable contact surface, and then the disk is cut from both left and right sides of the tooth base portion. Since the chips can flow out to the body surface, and the chips can smoothly flow without colliding with the front edge surface portion of the front surface of the tooth base portion, it is possible to prevent the wear of the portion, The tip saw can always be used in a safe state without lowering the strength of the body attachment point.

い。Since chips are immediately and smoothly discharged immediately after cutting, the cutting action of each chip body into the object to be cut and the cutting can be always performed satisfactorily. Therefore, even in the bush-cutting fields and mountainous areas where bushes are growing, chips can be easily removed from each chip.
Light cutting can be performed at all times, and the workability of the tip saw is extremely great for the operator with less fatigue.
