DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Field of Industrial Application) The present invention relates to a saw blade, and more specifically, for example, a band saw,
It relates to saw blades such as circular saws or saws.

(従来の技術) 従来、例えば金属性の大きなワークピースを切断(切
削)する装置として帯鋸盤が使用されている。
(Prior Art) Conventionally, for example, a band saw machine is used as a device for cutting (cutting) a workpiece having a large metal property.

帯鋸盤に使用される帯鋸刃においては、切粉のスムー
ズな排出と、直進性維持のため鋸刃にあさり出しが行な
われ、このあさり出し作業は、あさりを付けない歯、す
なわち直歯に対してあさり打ち出し量を数値で規定して
ある。
In the band saw blade used in the band saw machine, the saw blade is squeezed out in order to smoothly discharge chips and maintain straightness. The amount of hammering is specified numerically.

例えば第5図に示すごとく、鋸刃101の各歯(右あさ
り歯103R、左あさり歯105L、直歯107S)の切れ歯で作る
幅方向の線分a1〜a5は、所定の数値で均等にあさり出し
されている。
For example, as shown in FIG. 5, line segments a 1 to a 5 in the width direction formed by the teeth of each tooth of the saw blade 101 (right tooth 103R, left tooth 105L, straight tooth 107S) are given numerical values. It is evenly exposed.

なぜならば、一歯に大きな切削抵抗をかけないよう切
削作用を分散させ、安定した高速重切削が行なわれるよ
う構成されている。
This is because the cutting action is dispersed so that a large cutting resistance is not applied to one tooth, and stable high-speed heavy cutting is performed.

(Problems to be Solved by the Invention) As described above, the widthwise line segment a 1 to
a 5 can be set, but, the saw blade can not be maintained in long-term wear and shapes depending on the use.

すなわち、第6図に示すごとく、直歯107Sの摩耗量A

That is, as shown in FIG. 6, the wear amount A of the straight teeth 107S
On the other hand, comparing the wear amounts B of the left and right bevel teeth 103R and 105L, the wear amount B of the left and right bevel teeth 103R and 105L also progresses as the wear amount A of the straight teeth 107S wears.

摩耗が進行しAが完全に摩耗してしまうと、直歯107S

When wear progresses and A wears completely, straight teeth 107S
Of the line segment a 2 and a 4 are left and right set teeth 103R, 105L of the line segment a 1
And a 5 are absorbed, and the distribution of cutting resistance between the straight teeth 107S and the left and right flank teeth 103R and 105L is not uniform.

このため、左右のあさり歯103R、105Lの方が直歯107S
より抵抗が上廻り、更に第5図に示す分散切削を可能と

Therefore, the right and left set teeth 103R and 105L are straight teeth 107S.
Since the resistance is further increased and the effective height b of the straight teeth 107S which enables the distributed cutting shown in FIG. 5 is eliminated, it becomes impossible to divide the chip width.

Considering that the saw blade cutting is groove cutting, if the effective gullet area is constant, the straight teeth 107
S, the cutting action of the cutting chips by the right and left teeth 103R and 105L is eliminated, and the cutting width becomes the saw band thickness itself.

For this reason, there is a problem that the volume of cutting chips increases and it becomes difficult to stably discharge chips during high-speed heavy cutting.

[Effects of the Invention] As will be understood from the above description of the embodiments, in short, the present invention provides straight teeth (7S) that do not bend in the left-right direction as viewed in the traveling direction of the saw blade and bending in the right direction. Right crest (3R) and left crest (5L) bent left
And a second tooth tip line of the left and right set teeth (3R, 5L) with respect to a first tooth tip line of the straight tooth (7S), and an outside of the second tooth tip line is the first tooth tip line. The tip line of the left crest tooth (5L) is more inclined than the left corner of the tip of the right crest tooth (3R). In a saw blade with the right corner arranged on the right side, the tooth tips of the left and right teeth (3R, 5L) are pre-inclined so that the tilt angle after bending is larger, and the running direction of the saw blade As seen from the above, the inclination angle (θ 1 ) formed by the first tooth tip line and the second tooth tip lines of the left and right crest teeth (3R, 5L) after bending is
It is provided at an angle of 15 ° or more, and when viewed from the traveling direction of the saw blade, the first
From the crossing position of the tooth tip line of the second tooth tip line and the straight tooth (7
The effective height (H) of S) up to the first tooth tip line is set to 0.05 mm or more.

As is apparent from the above configuration, in the present invention, the inclination angle θ 1 formed by the tip lines of the right and left crust teeth 3R and 5L with respect to the tip line of the straight tooth 7S is set to 15 ° or more, and the straight tooth 7S
Since the effective height H of the above is set to 0.05 mm or more, the inclination angle θ 1 and the effective height H are larger than those of the conventional saw blade, and the straight teeth 7S and the left and right teeth 3R, 5L Even if the tooth tip of the tooth wears, the life until the effective height H becomes almost zero becomes long, and the dispersion of cutting resistance and the fragmentation of cutting chips for each tooth are prolonged. It can be maintained for a long time.

In particular, in the present invention, since the tooth tips of the left and right bevel teeth are pre-inclined so that the inclination angle after bending becomes larger, as described above, when the inclination angle θ 1 is formed to be 15 ° or more. However, the inner angles of the left and right set teeth 3R and 5L do not lie outside each other, which is a convenient construction for a saw blade for metal cutting.
