本発明は、鋸の改良に係り、例えは、ミシン鋸、ジグソ
ー鋸、金切り鋸等に適用される。DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to improvement of saws, and is applied to, for example, sewing machine saws, jigsaw saws, hack saws, and the like.
（従来の技術）
汎用の鋸としては、刃板が平板状をなし、刃板縁に削設

部を側方に突出させたものや、各刃片をアサリ取りした
鋸刃部分だけを波状に形成したものなどがあり、切断対
象とされる被切断物を切断し易くするために、被切断物
の性状に合わせて各刃片の形やアサリ取りを変えたりし
て多穐類の鋸が実用されている。(Conventional technology) A general-purpose saw has a flat blade plate, and a large number of blade plates are cut on the edge of the blade and are swung from side to side by a clam remover to make the tip of the blade protrude laterally. There are also saw blades that have a wavy shape in which only the saw blade section where each blade has been cut has a wavy shape.In order to make it easier to cut the object to be cut, each blade Polygonid saws have been put into practical use by changing the shape of the pieces and the way they handle clams.
（発明が解決しようとする課題） ところで、従来の鋸からすると次のような問題がある。(Problem to be solved by the invention) However, conventional saws have the following problems.
（ａ）鋸による切断作業では、鋸刃が被切断物に切り込
んで刃幅に相当する福で切込溝を形成するが、平板状の
刃板では刃板厚か切込溝の幅に比べて小さいために切断
時の直進性に欠ける。(a) In cutting work with a saw, the saw blade cuts into the object to be cut and forms a groove with a width corresponding to the width of the blade. Due to its small size, it lacks straightness when cutting.
（ｂ）直状をなす刃板では、切断時において刃幅の変化
は全くないので自在性に欠ける。(b) With a straight blade plate, the width of the blade does not change at all during cutting, so it lacks flexibility.
（Ｃ）各刃片をアサリ取りで左右に振らせて刃片先端部
を側方に突出させただけの鋸刃では、各刃片の共通の切
断線上で同一方向にばらつきが生じて切断能率が悪い。(C) With a saw blade in which each blade is simply swung left and right during shaving and the tip of the blade protrudes laterally, variations occur in the same direction on the common cutting line of each blade, resulting in reduced cutting efficiency. It's bad.
（ｄ）各刃片の側方に突出した刃先尖端により切込溝面
、即ち、切断面に掃き傷を生じて切断面の仕上り（切断
面の粗さ）を悪くする。(d) The sidewardly protruding tip of each blade causes sweeping scratches on the cutting groove surface, that is, the cutting surface, which deteriorates the finish of the cutting surface (roughness of the cutting surface).
（ｅ）切断時において各刃片と被切断物との摩擦によっ
て生しる摩擦熱が刃仮に篭もり、放熱性か悪い。(e) During cutting, the frictional heat generated by the friction between each blade and the object to be cut is trapped in the blade, resulting in poor heat dissipation.
本発明は、上記するような点を解決するなめに案出され
たもので、高性能の鋸を提供することを目的とする。The present invention was devised to solve the above-mentioned problems, and an object of the present invention is to provide a high-performance saw.

A part of the outer surface of the tip of each blade was removed, and a part of the outer surface of the tip of each blade that protruded laterally by forming the 3-blade plate in a wavy shape and swinging it from side to side during clam removal was removed. The saw features:

The width of the blade changes slightly, and the spring action is applied to the cutting surface and the saw blade, increasing the cutting speed due to its flexibility. By removing a portion of the outer surface of the tip of each blade, a straight side edge is formed on the side of each blade in the direction of the beam where the optical power of the blade intersects.
To improve straightness during cutting to increase cutting speed, to reduce scratches on the cut surface to give the cut surface a unique finish, and to improve heat dissipation of frictional heat written on the blade plate.

Engraving is more effective.
（発明の効果）
以上説明してきた如く本発明によれば、刃板を波状に形
成したことによって次のような効果を奏する。(Effects of the Invention) As explained above, according to the present invention, the following effects are achieved by forming the blade plate in a wave shape.
（ａ）相前後する各刃片の向きか僅かつつ刃板の湾曲に
沿って変化して同一方向とならないから、被切断物の切
断時の各刃片による切削は刃幅内において細かく分散独
立的に行われて各刃片の切削にはちつきかなく、切断能
率か向上する５
（ｂ）切断抵抗に対して刃ｉ長手方向く鋸挽き方向）に
弾力的伸縮かあって刃幅か僅かに変１ヒするから、切断
面と鋸刃に対してハネの１￥′、用か掛かり切断をし易
くし、自在性かあって力の入れ方による反応も円滑で切
断スピードを高める。(a) The direction of each successive blade changes slightly along the curvature of the blade plate and is not in the same direction, so the cutting by each blade when cutting the object to be cut is finely distributed and independent within the blade width. (b) There is elastic expansion and contraction in the longitudinal direction of the blade (in the sawing direction) against the cutting resistance, and the width of the blade is slightly reduced. Since it changes to 1 yen, it makes it easier to cut by applying force to the cutting surface and the saw blade, and because of its flexibility, it responds smoothly depending on how you apply force, increasing cutting speed.
（Ｃ）切断時に発生する切粉は、発生直後に刃板面凹部
に入って、逸早く切込溝外に出されるから、切込溝内に
残留する切粉によって切断作業が妨けられることかなく
、切断作業を円滑にする。(C) Immediately after the chips generated during cutting enter the recess on the blade surface and are quickly taken out of the cutting groove, the cutting work will not be hindered by chips remaining in the cutting groove. This makes cutting work smoother.
（ｄ）刃板面凹部は、切り込み隙間内において弾力的に
切断面に線接触的に摺接し、これをカイトとして各刃片
は切込溝内に動かされるから、切断時の直進性を向上す
る。(d) The concave part on the blade plate elastically slides in linear contact with the cutting surface within the cutting gap, and each blade piece is moved into the cutting groove using this as a kite, improving straightness during cutting. do.
アサリ取りて左右に振らせた各刃片の先端部外面を一部
削除したことによって次のような効果を奏する。The following effects are achieved by removing a portion of the outer surface of the tip of each blade that has been sharpened and swung left and right.
（ａ）天板厚に対して刃幅を小さく出来るがへ、切断時
の直進性か向上する。(a) The blade width can be made smaller relative to the thickness of the top plate, which improves straightness during cutting.
（ｂ）各刃片の外側面に縦方向に所定の長さの直状の側
刃か形成され、これが刃片の光力に交わるから被切断物
に対する切り込みがよく、切断スピードと高くして切断
能率が向上する。(b) A straight side blade of a predetermined length is formed on the outer surface of each blade, and since this crosses the optical power of the blade, it is possible to cut into the object to be cut easily, and the cutting speed can be increased. Improves cutting efficiency.
また、刃先と側刃との交わりが鋭角にならないから、刃
先と側刃とか交わるコーナー刃部の損耗による切断性能
の低下も少ない。Furthermore, since the intersection of the cutting edge and the side cutting edge does not form an acute angle, there is little reduction in cutting performance due to wear and tear on the corner cutting edge where the cutting edge and the side cutting edge intersect.
（Ｃ）各刃片の刃先と側刃とが交わるコーナー刃部は、
外向けに突出する尖端を有しないから切断面に対する掻
き傷が軽減されて切断面の仕上りを奇麗にする。また、
各刃片の先端部外面に形成される削除面が切断面に摺接
して放熱性も向上する。(C) The corner blade where the cutting edge of each blade intersects with the side blade is
Since it does not have an outwardly protruding point, scratches on the cut surface are reduced and the cut surface has a clean finish. Also,
The removed surface formed on the outer surface of the tip of each blade slides against the cutting surface, improving heat dissipation.
