Description
【０００１】[0001]
本考案は、多数の波形歯を周縁に備えた円形のチップソー（円形鋸歯）に関す るもので、主として木材や樹脂切断用に使用されるチップソーに関するものであ る。 The present invention relates to a circular tip saw (circular saw tooth) having a large number of corrugated teeth on its periphery, and mainly to a tip saw used for cutting wood and resin.
【０００２】[0002]
従来、この種のチップソーは図４に示すように、先端を鋭突とした指向性のあ る凸部１１…と凹部１２…の繰り返しによる波形歯１３が周縁に形成され、波形 歯１３の切削側先端には超硬合金１４が埋め込まれて形成されている。 Conventionally, as shown in FIG. 4, a tip saw of this type has a corrugated tooth 13 formed on the periphery by repeating a convex portion 11 ... And a concave portion 12 ... Cemented carbide 14 is embedded in the side tip.
【０００３】[0003]
この従来のチップソーにあっても、一般的な木材の通常回転による切削には充 分対応することができるが、しかし堅い木材や樹脂等の高速切断に際しては、切 り粉の飛散が十分でなく、焼き付きや刃こぼれ等の生じる恐れがあった。 This conventional tip saw can also be used for cutting ordinary wood with normal rotation, but when high-speed cutting of hard wood or resin, the scattering of cutting chips is not sufficient. There was a risk of burn-in and blade spillage.
【０００４】 そこで本考案は、切削によって生じる切り粉を素早く飛散させるようにして波 形歯の凹部に滞留することを無くし、これにより少ない切削抵抗で高速切断でき るようにしたチップソーを提供することを主たる目的とするものである。Therefore, the present invention provides a tip saw that quickly disperses the cutting chips generated by cutting so as not to stay in the concave portions of the corrugated teeth, thereby enabling high-speed cutting with less cutting resistance. Is the main purpose.
【０００５】[0005]
上記目的を達成する為に本考案では次のような技術的手段を講じた。即ち、本 考案に係るチップソーにあっては、側面からみて、先端を鋭突とした指向性のあ る凸部１…と凹部２…の繰り返しによる波形歯３を周縁に備えた円形のチップソ ーにおいて、前記凹部２に沿って所定巾の傾斜切込み４、４’…がチップソーの 左右側面で交互に形成されており、該傾斜切込み４、４’…は凹部２の稜線に向 かってその厚みが徐々に薄くなるように傾斜して形成されている構造としたもの である。 In order to achieve the above object, the present invention takes the following technical means. That is, in the tip saw according to the present invention, as seen from the side, a circular tip saw having corrugated teeth 3 on the periphery by repeating the convex portion 1 ... And the concave portion 2 ... , The inclined cuts 4, 4 ′ of a predetermined width are alternately formed on the left and right side surfaces of the tip saw along the recess 2, and the inclined cuts 4, 4 ′ have a thickness toward the ridge of the recess 2. The structure is such that it is formed so that it gradually becomes thinner.

以下本考案の実施例を図面に基づいて説明する。図１〜図３は本考案に係る円 形チップソーの一実施例を示すものであって、側面からみて、先端を鋭突とした 指向性のある凸部１…と凹部２…の繰り返しによる波形歯３を周縁に備えており 、該波形歯３の切削側先端部分には超硬合金５…が埋め込まれ、その先端に鋭突 な刃５ａが形成されている。 Hereinafter, embodiments of the present invention will be described with reference to the drawings. 1 to 3 show an embodiment of a circular tip saw according to the present invention, which is a waveform obtained by repeating a directional convex portion 1 ... And a concave portion 2 ... Teeth 3 are provided on the periphery, and cemented carbide 5 is embedded in the cutting-side tip portion of the corrugated tooth 3, and a sharp blade 5a is formed at the tip.
【０００７】 更に、前記凹部２に沿って所定巾の傾斜切込み４、４’…がチップソーの左右 側面で交互に形成されている。即ち図２に示すように、左右側面で傾斜切込み４ 、４’が交互になるように形成されている。またこの傾斜切込み４、４’…は、 図３に示すように、凹部２の稜線２ａに向かってその厚みが徐々に薄くなるよう に傾斜して形成されている。尚、前記傾斜切込み４、４’は図２で示すようにそ の上端が超硬合金５…に連なるように形成しておくのがこのましい。尚、図中６ は機械に取り付けるための取付穴を示すものである。Further, inclined cuts 4, 4 ′ having a predetermined width are alternately formed along the concave portion 2 on the left and right side surfaces of the tip saw. That is, as shown in FIG. 2, inclined cuts 4 and 4'are formed alternately on the left and right side surfaces. Further, as shown in FIG. 3, the inclined cuts 4, 4 '... are formed so as to be inclined toward the ridgeline 2a of the recess 2 so that the thickness thereof is gradually reduced. It is preferable that the inclined notches 4 and 4'be formed so that their upper ends are continuous with the cemented carbide 5, ... As shown in FIG. Reference numeral 6 in the figure denotes a mounting hole for mounting on a machine.
【０００８】 上記のごとく構成されたチップソーにあっては、切削の際に凹部２に送られた 切り粉は、凹部２の稜線２ａに向かってその厚みが徐々に薄くなるように傾斜し て形成されている傾斜切込み４、４’によって外部に素早く飛散され、これによ り凹部２に切り粉が滞留することを無くし、少ない摩擦抵抗で高速切断が可能と なる。また、切り粉の流れは、超硬合金の刃先５ａから図２の矢印で示すように 傾斜切込み４、４’に沿って流れるため、切り粉の素早い飛散を助長する。In the tip saw configured as described above, the cutting dust sent to the recess 2 at the time of cutting is formed by inclining toward the ridgeline 2 a of the recess 2 so that the thickness thereof gradually decreases. The slanted cuts 4 and 4'are quickly scattered to the outside, whereby it is possible to prevent the cutting powder from accumulating in the recess 2 and to perform high-speed cutting with less frictional resistance. Further, the flow of the cutting chips flows from the cemented carbide blade edge 5a along the inclined cuts 4 and 4'as shown by the arrow in FIG.
【０００９】 尚、本考案では前記傾斜切込み４、４’の巾や傾斜角度等の寸法は被切削物の 材質に応じて設定される。また、本考案のチップソーは木材や樹脂に限らず、金 属切断用のチップソーにも応用できることは勿論である。In the present invention, the dimensions such as the width and the inclination angle of the inclined cuts 4 and 4'are set according to the material of the workpiece. The tip saw of the present invention is not limited to wood and resin, and can be applied to a tip saw for metal cutting.
【００１０】 以上本考案の代表的と思われる実施例について説明したが、本考案は必ずしも これらの実施例構造のみに限定されるものでなく、本考案の構成要件を備え、か つ前記の目的を達成し、下記の効果を有する限りにおいては適宜に改変して実施 することができる。Although the embodiments considered to be typical of the present invention have been described above, the present invention is not necessarily limited only to the structures of these embodiments, and has the constituent features of the present invention and the above-mentioned object. Can be carried out with appropriate modification as long as the above is achieved and the following effects are obtained.
【００１１】[0011]
本考案のチップソーは上記の如く構成されているので、切削によって生じる切 り粉を傾斜切込みから素早く飛散させることができ、これにより波形歯の凹部に 切り粉が滞留することがなくなって切削抵抗が少なくなり、高速回転による迅速 な切断をスムースに行うことができる、といった顕著な効果がある。 Since the tip saw of the present invention is configured as described above, it is possible to quickly disperse the cutting chips generated by cutting from the slanted cuts, thereby preventing the cutting chips from accumulating in the concave portions of the corrugated teeth and cutting resistance. There is a remarkable effect that it can be cut smoothly and quick cutting can be smoothly performed by high speed rotation.
