〈実施例〉
以下には、図面を参照して、この発明の実施例について
詳細に説明をする。<Embodiments> Examples of the present invention will be described in detail below with reference to the drawings.
第１図は、この発明の一実施例に係る鋸歯の構造を表わ

面図である。FIG. 1 is a side view showing the structure of a sawtooth according to an embodiment of the present invention, and FIG. 2 is a sectional view taken along the line - H in FIG. 1.
第１図および第２図を参照して説明すると、−連の鋸歯
１．ｌ、・・・には、交互に異なる片面の先端部に硬質
物２が結着されている。硬質物２は、たとえばステライ
ト、イソライト、タンガロイなどの合金で構成されてい
る。Referring to FIGS. 1 and 2, the series of saw teeth 1. 1, . . . have hard substances 2 bound to the tips of alternately different sides. The hard material 2 is made of an alloy such as stellite, isolite, or tangaloy.
硬質物２は、第２図に明確に示されるように、鋸歯ｌの

へ振分けることなく、アサリの機能が備えられているの
である。As clearly shown in FIG. 2, the hard material 2 is bonded to the side surface of the tip of the sawtooth 1, so it functions as a set for the sawtooth 1. That is, in general, the tips of the sawtooth 1 are alternately distributed to the left and right sides and set with a set edge to widen the tip width, thereby reducing frictional resistance during cutting. In the sawtooth of this embodiment, by binding the hard material 2 to the tip of the side surface of the sawtooth 1, the sawtooth 1 can be provided with a setting function without having to divide the sawtooth 1 into left and right sides.
また、図示のような横引き用の鋸歯１には、それぞれ、

述の表刃１１、裏刃１２、人力１３および歯の天１４が
、いずれも硬質物２によって作られている。In addition, the saw teeth 1 for horizontal pulling as shown in the figure each include:
It includes a front blade 11 that exists in the sawing direction, a back blade 12 that exists in the sawing direction, and a human power 13 that exists at the tip. 14
is the top of Sawtooth 1. In this embodiment, the above-mentioned front blade 11, back blade 12, manpower 13, and tooth top 14 are all made of the hard material 2.
従って、鋸歯１における木材等と接する部分すなわち木
材を切断する場合に切断に作用する部分は、硬質物２で
あるため、長期間使用しても摩耗等が少なく、切味が持
続する鋸歯１となっている。Therefore, since the part of the sawtooth 1 that comes into contact with wood, etc., that is, the part that acts on cutting when cutting wood, is a hard material 2, the sawtooth 1 has little wear and maintains its sharpness even after long-term use. It has become.
次に、この発明の一実施例に係る鋸歯の製造方法につい
て、第３図を参照して説明をする。Next, a method for manufacturing a saw tooth according to an embodiment of the present invention will be explained with reference to FIG.
第３図（Ａ）に示すように、のこ身の形に形抜きされた
焼入鋼板に切込みを形成し、後に鋸歯となる一連の複数
の山１０，１０．・・・を形成する。As shown in FIG. 3(A), cuts are formed in a hardened steel plate cut into the shape of a saw, and a series of ridges 10, 10. ... to form.
このように山１０，１０．・・・を形成すると、次の工
程で硬質物を鎔着する際に、のこ身が熱を帯びても、歪
み等が生じることがないという利点がある。Like this, mountains 10, 10. . . . is advantageous in that even if the saw body becomes heated during the next step of welding a hard material, no distortion or the like will occur.
次に、第３図（Ｂ）に示すように、冬山１０゜１０、・
・・に対して、交互に異なる片面側に硬質物２を結着す
る。硬質物２は、高温に加熱して溶かし、雫状にして山
の上に付着させる。あるいは、他の方法によって鎔着し
てもよい。Next, as shown in Figure 3 (B), Fuyuyama 10°10,
. . . The hard materials 2 are bonded to alternately different sides. The hard substance 2 is heated to a high temperature, melted, and formed into droplets and attached to the top of the mountain. Alternatively, it may be attached by other methods.
硬質物２の結着が終了した鋸歯は、正面図側から見ると
、第３図（Ｃ）に示すように硬質物２が両側面および上
側に不均一に膨らんでいることが多い。そこで、第３図
（Ｄ）に示すように、研磨装置によって鎔着された硬質
物の両側面および上端縁を研磨する。When the sawtooth to which the hard material 2 has been bound is viewed from the front view, the hard material 2 often bulges unevenly on both sides and the top, as shown in FIG. 3(C). Therefore, as shown in FIG. 3(D), both side surfaces and the upper edge of the hard material that has been fixed are polished by a polishing device.
この結果、のこ身は正面側から見ると第３図（Ｅ）に示
すようになる。As a result, the saw body becomes as shown in FIG. 3(E) when viewed from the front side.
次に、第３図（Ｆ）に示すように、ダイヤモンドカッタ
等の治具を利用して、歯付加工を行うことにより、鋸歯
１が完成する。Next, as shown in FIG. 3(F), the sawtooth 1 is completed by performing toothing processing using a jig such as a diamond cutter.

。FIG. 4 is a side view showing the structure of a saw tooth according to another embodiment of the present invention, and FIG. 5 is a side view showing the state immediately after a hard material is attached in the manufacturing process of the saw tooth of FIG. It is a diagram.
第４図に示すように、目が小さい鋸歯の場合、すなわち
鋸歯のピッチが小さい場合には、一連の鋸歯１に対し、
交互に異なる片面に硬質物２を鎔着するのではなく、連
続する所定数の鋸歯１（図示では連続する２つの鋸歯１

は４つの鋸歯であってもよい。）に対して同一の片面側
に硬質物２を鎔着し、その鎔着面が鋸歯所定数ごとに交
互に反転されるようにしてもよい。As shown in FIG. 4, in the case of saw teeth with small eyes, that is, when the pitch of the saw teeth is small, for a series of saw teeth 1,
Rather than attaching the hard material 2 to different surfaces alternately, a predetermined number of consecutive sawtooths 1 (in the illustration, two consecutive sawtooths 1)
, 1, but the present invention is not limited thereto, and may be three or four consecutive sawtooths. ), the hard material 2 may be attached to the same one side, and the attached surface may be alternately reversed every predetermined number of saw teeth.
たとえば精密加工に必要な細目の大工鋸等を製造する場
合においては、鋸歯１の目が小さいので、鋸歯１つずつ
に硬質物２を結着することは困難である。そこで、第５
図に示すように、連続する複数の鋸歯１に対してまとめ
て硬質物２を鎔着し、それを交互に異なる片面側に施せ
ばよい。For example, when manufacturing a fine carpenter's saw required for precision machining, it is difficult to bond the hard material 2 to each saw tooth because the saw teeth 1 have small openings. Therefore, the fifth
As shown in the figure, the hard material 2 may be attached to a plurality of consecutive sawteeth 1 at once, and the hard material 2 may be applied alternately to different sides.
つまり、連続する複数個の鋸歯１を単位として硬質物２
の鎔着を行うことにより、微細な鋸歯１に対する結着加
工が容易に行えるのである。In other words, a plurality of consecutive sawtooths 1 are used as a unit for hard objects 2.
By performing the bonding process, the bonding process to the fine sawtooth 1 can be easily performed.
この場合、硬質物２は、鋸歯１全体に結着されることに
なるが、側段支障はない。In this case, the hard material 2 will be bonded to the entire sawtooth 1, but there will be no side hindrance.
以上の各実施例では、鋸歯が横引き用の歯をとりあげた
が、縦引き用の鋸歯であっても、この発明を適用できる
。また、手挽鋸をはじめ、丸鋸等の鋸歯にもこの発明を
利用できる。In each of the above embodiments, the saw teeth are used for horizontal pulling, but the present invention can also be applied to saw teeth for vertical pulling. Furthermore, the present invention can be applied to saw blades such as hand saws and circular saws.
