この発明は、各リード刃に罫引方形状の超硬材刃を取付
けた木工用の円部刃に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a circular blade for woodworking in which each lead blade is provided with a carbide blade in the form of a square.
一般に円部刃は一つの平切削刃と次位の平切削刃との間
に数対のリード刃を配置し、偶数の総刃数から形成され
、木材の縦切り又は横切りに関わらず先ずリード刃が溝
縁を切り込み、平切削刃が ゛溝形を切削していく構造
となっている。In general, circular blades are formed by arranging several pairs of lead blades between one flat cutting blade and the next flat cutting blade, and have an even number of total blades. The blade cuts into the groove edge, and the flat cutting blade cuts the groove shape.
そして、名刀の先端には円部本体を形成する鋼材よりも
超硬材のタンガロイ等の付刃を通常鑞付は等により取付
けて形成されている。At the tip of the famous sword, a blade made of a carbide material such as Tungaloy, rather than the steel material forming the circular body, is usually attached by brazing or the like.
しかし問題はこれらリード刃の形状にあって、従来のリ
ード刃の刃先縦断面はすべて鋭角の針状に形成されてい
るため、刃先先端は木材繊維に突きささる傾向を示し、
スムーズに切削していくことができず、全般に切れ味が
悪い傾向があった。However, the problem lies in the shape of these reed blades.The vertical section of the cutting edge of conventional reed blades is all shaped like an acute needle, so the tip of the cutting edge tends to pierce wood fibers.
It was not possible to cut smoothly, and the cutting quality tended to be poor overall.
そこでこの発明は、上記各リード刃の刃先先端を罫引刃
の形状のように刃先縦断面を鈍角状又は円弧状に形成し
たもので、このように形成することによってリード刃の
先端は木材繊維に対し直線的に切り込んでいくのでスム
ーズに切削し、実験によるとその切れ味は従来の数倍も
向上することが確かめられ、全体の刃数も２分の１程度
に低減でき、高性能の円部を提供できるものである。Therefore, in this invention, the tip of each reed blade is formed to have an obtuse-angled or arcuate vertical cross-section like the shape of a creasing blade. Since it cuts in a straight line, it cuts smoothly, and experiments have confirmed that the sharpness is several times better than conventional ones.The total number of teeth can be reduced to about half, making it possible to cut with high performance. It is possible to provide the following:
以下本発明の一実施例を図面に従って説明すると、円部

刃先縦断面が鈍角又は円弧状の罫引方形状の付刃（３）
を取付けて成る円部刃である。An embodiment of the present invention will be described below with reference to the drawings. In the circular part (2), each lead blade (2) is made of a carbide material and has an obtuse or arcuate vertical section. )
It is a circular blade with a .

ていくので切れ味、仕上りともに向上するものである。In the circular blade of the present invention constructed in this manner, the longitudinal section of the cutting edge of each lead blade is formed in an obtuse-angled or arc-shaped ruled rectangular shape, so that the cut to the groove edge is made in a straight line to the wood fibers. Since the cutting edge cuts at a sharp angle, the cutting edge cuts smoothly without the tendency of the cutting edge to pierce or pierce, compared to the conventional acute-angled cutting edge, which improves both sharpness and finish.

である。In this way, in the present invention, the longitudinal section of the cutting edge of each lead blade is formed into an obtuse-angled or arc-shaped ruled shape, so it shows several times the sharpness and has a better finish compared to the conventional acute-angled one. This is a groundbreaking high-performance circular saw blade that has many benefits such as increased durability, reduced number of blades, and lower manufacturing costs.
