Abstract
Description
【発明の詳細な説明】 この発明は鋸の製造方法の改良に関するものである。[Detailed description of the invention] This invention relates to an improvement in a method for manufacturing a saw.
大工用両刃鋸折込鋸や丸鋸等の鋸は切れ味をよくし且つ
木材との摩擦抵抗を少なくするため９こ刃部の厚みより
身部を蒲＜シている。Carpenters' double-edged saws, folding saws, circular saws, and other saws have their body parts thicker than the 9-blade part to improve sharpness and reduce frictional resistance with wood.
前記青部分を薄くする方法は一般に研磨によっており、
作業に著しい労力を要するにもかへわらず均一な仕上げ
を求め得す、且つ刃と身の境界部分の研磨には熟練を要
し、量産への障害となっていた。The method of thinning the blue part is generally by polishing.
Even though the work required considerable effort, a uniform finish could be obtained, and polishing the boundary between the blade and the body required skill, which was an obstacle to mass production.
この発明は上記従来の欠点を解決したもので、その目的
とするところは青部分を薄くするのに研磨作業を廃し、
鋸素材を薬液噴霧トンネル内を通過させるだけで足りる
、工程が著しく簡単要易で、且つ薄肉とすべき部分の肉
厚にバラツキがない鋸の製造方法を提供するにある。This invention solves the above-mentioned conventional drawbacks, and its purpose is to eliminate the need for polishing to thin the blue part.
To provide a method for manufacturing a saw which requires only passing a saw material through a chemical spray tunnel, which is a very simple and easy process, and which has no variation in wall thickness at a portion to be made thin.
以下この発明の構成を添付図面に基いて説明すれば、第
１図第２図においてＡは薄鋼板から得られた鋸素材であ
り、図示の素材は鋸の一例としての剪定用である。The structure of the present invention will be described below with reference to the accompanying drawings. In FIGS. 1 and 2, A is a saw material obtained from a thin steel plate, and the illustrated material is an example of a saw for pruning.
この素材には刃を形成すべき部分１と柄部分２に飼犬ば
エツチング用レジスターインキの如き酸に対し耐蝕性の
被膜３（インキ）が印刷等で形成され、青部分４のみが
露出させである。On this material, a coating 3 (ink) that is resistant to acids, such as register ink for dog etching, is formed by printing on the part 1 where the blade is to be formed and the handle part 2, and only the blue part 4 is left exposed. be.
前記のようにして得られた鋸素材Ａ−は、３ｏ″Ｃｇ）
塩化第２鉄液、硫酸、硝酸、塩酸等の鋼腐蝕用液を吹付
ける。吹付は時間は鋸の種類によるが大工用両刃鋸等は
約１０分間としあと水洗する。The saw material A- obtained as described above is 3o''Cg)
Spray a steel corrosion solution such as ferric chloride solution, sulfuric acid, nitric acid, or hydrochloric acid. The spraying time depends on the type of saw, but for carpenter's double-edged saws etc., spray for about 10 minutes and then rinse with water.
第３図第４図Ａ−１は水洗後被膜３を除去し、刃部１に
多数の歯５を形成した成品を示しており、被膜が形成さ
れていた部分以外の金属露出部分即ち青部分４ａは腐蝕
されて肉厚が薄くなっている。3 and 4 A-1 show a product in which the coating 3 has been removed after washing with water and a large number of teeth 5 have been formed on the blade portion 1, and the exposed metal portion other than the portion where the coating was formed, that is, the blue portion. 4a has been corroded and its wall thickness has become thinner.
尚各歯５には次工程であさり（歯振り）が施こされる。Incidentally, each tooth 5 is subjected to a shaving (tooth swinging) in the next step.
この本発明は、上記したような製法であり、鋸素材の刃
を形成すべき部分や柄部分を耐蝕性被膜で覆い鋼腐蝕用
液で腐蝕させるものであるから、被膜が存在していた部
分以外の部分、特に刃部分を除き青部分のみが腐蝕され
て肉厚が小になると共にこの部分の肉厚が均一であり、
且つ肉厚を手番こする工程が著しく容易で確実を期し得
るという効果がある。The present invention is a manufacturing method as described above, in which the part where the blade is to be formed and the handle part of the saw material are covered with a corrosion-resistant coating and corroded with a steel corrosive solution, so the parts where the coating was present are Except for the other parts, especially the blade part, only the blue part is corroded and the wall thickness becomes smaller, and the wall thickness of this part is uniform.
In addition, the process of manually rubbing the wall thickness is extremely easy and reliable.
又この発明の他の１つの構成は第５図第６図に示すよう
に、鋸素材Ｂに形成する被膜３ａ中、刃各歯５ａを形成
すべき部分ではその表面側のみに形成したものである（
池の工程は前記発明と全く同じであるから省略）から各
歯５ａを形成すべき部分ではその裏面側すに被膜を施こ
さないので、鋼腐蝕用液の吹付けにより各歯の裏面すも
青部分４ａ同様に腐蝕させることができ、従ってこの方
法によれば得られた成品鋸Ｂ−１における各歯にあさり
（歯振り）を施こす必要がなく、製造工程を更に容易且
確実番こなし得るという効果がある。Another configuration of the present invention is that, as shown in FIGS. 5 and 6, in the coating 3a formed on the saw material B, each blade tooth 5a is formed only on the surface side of the portion where each blade tooth 5a is to be formed. be(
Since the coating process is exactly the same as that of the above invention, it is omitted), and since no coating is applied to the back side of the portion where each tooth 5a is to be formed, the back side of each tooth is coated by spraying a steel corrosive solution. It can be corroded in the same way as the blue part 4a, and therefore, according to this method, there is no need to gouge each tooth in the finished product saw B-1, making the manufacturing process easier and more reliable. It has the effect of gaining.
