〈産業上の利用分野〉
本考案は、丸のこ特に腰入れ処理を不要とすべ
く改良した丸のこに関する。[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a circular saw, and particularly to a circular saw that has been improved so as to eliminate the need for tightening.
〈従来技術とその問題点〉
丸のこのような薄肉円盤状の工具で高速切削す
ると、歯先の発熱により外周部付近にゆるみが生
ずる。この結果、振動や騒音を発するほか、切削
面を荒したりひき割りを起す。<Prior art and its problems> When cutting at high speed with a thin disc-shaped tool such as a circular saw, heat generation at the tooth tip causes loosening near the outer periphery. As a result, in addition to producing vibration and noise, the cutting surface becomes rough and cracks occur.
これを防ぐため、従来はのこ身の中央部をつち
打ちする腰入れ処理をしていた。この作業は、昔
から経験と勘にのみ頼つていた。このため、長期
の修業が必要となつて、丸のこ製作上の大きな問
題点の一つとなつていた。 In order to prevent this, conventionally the central part of the saw body was hammered into the waist. This work has traditionally relied solely on experience and intuition. For this reason, long-term training was required, which was one of the major problems in circular saw production.
〈考案の構成〉
本考案は、この面倒な腰入れを不要とすべく改
良した丸のこで、つぎのように構成する。<Structure of the invention> The present invention is a circular saw that has been improved to eliminate the need for this troublesome installation, and is constructed as follows.
すなわち丸のこののこ身の外周寄りと内側とに
複数段に分けて外周から内方へ向うスリツトを、
それぞれ複数本づつ設け、各スリツトの溝幅を切
粉が詰まらない程度に狭くすると共に、両端に孔
をあけ、且つ内側のスリツトの外端を外周寄りの
スリツトの内端より外周寄りに位置させてなる丸
のこである。 In other words, the slits are made in multiple stages near the outer periphery and on the inside of the circular saw body, going inward from the outer periphery.
A plurality of each slit is provided, the width of the groove of each slit is narrowed to such an extent that chips do not clog the groove, and holes are formed at both ends, and the outer end of the inner slit is positioned closer to the outer periphery than the inner end of the slit near the outer periphery. It is a circular saw.
〈作用〉
腰入れは、のこ身の中央部をつち打ちして、こ
の部分に内部応力をもたせて、歯先の発熱による
ゆるみと釣り合わせることにより、外周部のゆる
みから生ずる欠点を避けようとする処理である。<Function> In the case of waist inserts, the central part of the saw body is hammered to create internal stress in this part, which counterbalances the loosening caused by heat generation at the tips of the teeth, thereby avoiding defects caused by loosening of the outer periphery. This is the process we are trying to do.
これに対し、本考案はのこ身に外周から内方へ
向うスリツトを複数本設け、且つ内側のスリツト
の外端を外周寄りのスリツトの内端より外周寄り
になるよう位置させた。この結果歯先の発熱によ
るゆるみは、このスリツトによりたち切られて他
部分に及ばない。このため、腰入れにより中央部
へ内部応力を貯えなくとも、発熱による不都合を
防止できる。 In contrast, in the present invention, a saw body is provided with a plurality of slits extending inward from the outer periphery, and the outer ends of the inner slits are positioned closer to the outer periphery than the inner ends of the slits closer to the outer periphery. As a result, the loosening of the tooth tip due to heat generation is immediately cut off by the slit and does not spread to other parts. For this reason, the inconvenience caused by heat generation can be prevented without storing internal stress in the central part due to waist insertion.
〈実施例〉
以下に本考案の実施例を図面に基いて説明す
る。<Examples> Examples of the present invention will be described below based on the drawings.
丸のこ１ののこ身２の外周寄りと内側とに二段
に分けて、それぞれに外周から内方へ及ぶスリツ
ト３を複数本設ける。スリツト３の両端には孔４
をあけて、割れがひろがるのを防ぐ。外周寄りの
スリツト３１は外端が歯先５に及んでいるため不
要。スリツト３の溝幅は、切粉が詰まらない程度
に狭くする。 The saw body 2 of a circular saw 1 is divided into two stages near the outer periphery and inside, and a plurality of slits 3 extending from the outer periphery to the inside are provided in each stage. Holes 4 are provided at both ends of the slit 3.
Open it to prevent the crack from spreading. The slit 31 near the outer periphery is unnecessary because the outer end extends to the tooth tip 5. The groove width of the slit 3 is made narrow enough not to be clogged with chips.
内側のスリツト３２の外端６を、外周寄りのス
リツト３１の内端７より外周寄りになるよう位置
させる。このようにする理由は、隣り合う外周寄
りのスリツト３１，３１間を、内側のスリツト３
２で分断することにより、発熱によるゆるみをた
ち切るためである。 The outer end 6 of the inner slit 32 is positioned closer to the outer periphery than the inner end 7 of the slit 31, which is closer to the outer periphery. The reason for doing this is that between the adjacent slits 31 near the outer periphery, the inner slit 3
This is to prevent loosening due to heat generation by dividing at 2.
〈考案の効果〉
本考案は以上説明したように、のこ身の外周寄
りと内側とに分けて、外周から内方へ向うスリツ
トを、複数本づつ設けた。このため、歯先の発熱
によるゆるみが、たち切られて他へ及ばないの
で、腰入れにより内部応力を与えなくとも、発熱
によるゆるみからくる障害を生じない丸のことな
る。<Effects of the invention> As explained above, in the present invention, a plurality of slits are provided inwardly from the outer periphery of the saw body, separated into the outer periphery and the inner side. For this reason, any loosening caused by heat generation at the tips of the teeth is immediately cut off and does not spread to the other parts, so even if internal stress is not applied by tightening, the circular saw will not cause problems due to loosening caused by heat generation.
