Description
【発明の詳細な説明】 〔産業上の利用分野〕 この発明は、断面が半円弧状部分を持つ中間駒により
連結される連結駒の製造方法に関する。TECHNICAL FIELD The present invention relates to a method for manufacturing a connecting piece connected by an intermediate piece having a semi-circular arc-shaped cross section.
従来のバンド用連結駒の製造方法である特開昭58−14
04号公報を、第６図乃至第９図の斜視図に示す。A conventional method for manufacturing a band connecting piece is disclosed in Japanese Patent Laid-Open No. 58-14.
Publication 04 is shown in perspective views in FIGS. 6 to 9.
この製造方法は、まず、連結駒となる金属棒材の側面
にダイス引き又はロール引きにより溝を形成し（第６
図）、前記棒材とは異なる材質の金属線材を上記溝内に
挿入し（第７図）、線材のまわりに溝側面の棒材庇部を
縁曲げした後に（第８図）、線材を可溶の溶媒に浸漬し
て、線材を溶解除去するものである（第９図）。In this manufacturing method, first, a groove is formed on a side surface of a metal rod material serving as a connecting piece by die drawing or roll drawing (6th embodiment).
Fig.), A metal wire rod made of a material different from that of the rod is inserted into the groove (Fig. 7), and the rod eaves on the side surface of the groove are bent around the wire (Fig. 8). The wire is dissolved and removed by immersing it in a soluble solvent (Fig. 9).
しかしながら、従来例の製造方法では、連結駒に溝を
設けるのに、金属棒材のダイス引き又はロール引きによ
り行っているため、溝を設ける前に、連結駒の表面に模
様付はできない。However, in the manufacturing method of the conventional example, since the groove is formed in the connecting piece by the die drawing or the roll drawing of the metal rod, the surface of the connecting piece cannot be patterned before the groove is formed.
また、溝を設けた後は、模様付のための型打ちを行な
うと、溝が変形するため、この場合も模様付ができな
い。Further, after the groove is provided, if stamping for patterning is performed, the groove is deformed, and thus patterning cannot be performed in this case as well.
そこで従来、このような構造の連結駒は、表面がフラ
ットなものしかできなかった。Therefore, conventionally, the connecting piece having such a structure can only have a flat surface.
更に溝の中に圧入されている金属線材である真鍮を溶
かすために硝酸液に入れるため、連結駒は硝酸等に溶け
ない材料でなければならない。Furthermore, since brass, which is a metal wire rod press-fitted into the groove, is put into nitric acid solution to dissolve it, the connecting piece must be a material that does not dissolve in nitric acid or the like.
しかも、ダイス引きの前や硝酸液にひたす前はメッキ
等の表面処理が行なえないという不便さがあった。Moreover, there is an inconvenience that the surface treatment such as plating cannot be performed before the die drawing or the dipping in the nitric acid solution.
この発明は、上記問題点を解決するために創作された
もので、連結駒を作るのに金属棒材のダイス引き、ロー
ル引きを必要とせず、また、プレスによる型打ちが行な
えるバンド用連結駒の製造方法を提供するものである。This invention was created to solve the above problems, and does not require die drawing or roll drawing of a metal rod to form a connecting piece, and is a band connection that can be stamped by a press. A piece manufacturing method is provided.
この発明は、連結駒の側面にフライスカッターで溝を
設け、前記溝の入口より挿入し、刃先を斜上方に向けた
フライスカッターで前記溝の内部上方を切削し、前記溝
の入口より挿入し、刃先を斜下方に向けたフライスカッ
ターで前記溝の内部下方を切削したものである。This invention provides a groove on the side surface of the connecting piece with a milling cutter, inserts from the entrance of the groove, cuts the inside upper part of the groove with a milling cutter with the blade edge directed obliquely upward, inserts from the entrance of the groove, The inside lower part of the groove is cut by a milling cutter whose blade edge is directed obliquely downward.
以下、この発明の実施例を図面に基づいて詳述する。 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
第１図より第４図はこの発明の第１実施例を示し、第
１図は切削工程を示す断面図、第２図はフライスカッタ
ーで溝を切削している状態を示す断面図、第３図は第２
図を上から見た平面図、第４図はこの発明の連結駒を用
いて、バンドを組立てた状態を示す断面図である。1 to 4 show a first embodiment of the present invention, FIG. 1 is a sectional view showing a cutting step, FIG. 2 is a sectional view showing a state in which a groove is being cut by a milling cutter, and FIG. The figure is the second
FIG. 4 is a plan view of the drawing seen from above, and FIG. 4 is a sectional view showing a state in which a band is assembled using the connecting piece of the present invention.
連結駒１の側面1aに、フライスカッター２で溝1bを設
ける（第１図（１）、（２））。A groove 1b is provided on the side surface 1a of the connecting piece 1 with a milling cutter 2 (FIGS. 1 (1) and (2)).
次に、溝1bの入口1cより、フライスカッターの刃先2a
を斜上方に向けて挿入し、溝1bの内部上方1dを切削する
（第１図（３）、（４））。Next, from the entrance 1c of the groove 1b, to the cutting edge 2a of the milling cutter.
Is inserted obliquely upward, and the inner upper portion 1d of the groove 1b is cut (FIG. 1 (3), (4)).
同様に、溝1bの入口より、フライスカッターの刃先2a
を斜下方に向けて挿入し、溝1bの内部下方1eを切削し
て、連結駒１の溝の切削を完了する（第１図（５）、
（６）、（７））。Similarly, from the entrance of the groove 1b, the cutting edge 2a of the milling cutter
Is inserted obliquely downward, the inner lower part 1e of the groove 1b is cut, and the cutting of the groove of the connecting piece 1 is completed (Fig. 1 (5),
(6), (7)).
具体的な切削方法は、第２図、第３図に示すように、
連結駒１を保持具３で保持し、カッター軸４を中心に回
転するフライスカッターで溝を設ける。The specific cutting method is as shown in FIG. 2 and FIG.
The connecting piece 1 is held by a holder 3, and a groove is provided by a milling cutter that rotates around a cutter shaft 4.
なお、溝は３回に分けて切削するため、この発明の方
法で切削した場合は、わずかに段差が生じるが、バンド
としての機能には全く影響を与えない。Since the groove is cut in three steps, when it is cut by the method of the present invention, a slight step is formed, but it does not affect the function as a band at all.
また、フライスカッターの刃先を円弧状にしておくこ
とにより、上記段差を小さくできる。Further, by making the blade edge of the milling cutter arc-shaped, the step can be reduced.
上記のようにして作られた連結駒１は、第４図に示す
ように、中間駒５を介して連結される。The connecting piece 1 made as described above is connected via the intermediate piece 5, as shown in FIG.
第５図の斜視図は、この発明の第２実施例を示し、連
結駒１の表面にプレスによる型打ちで、模様1fを付けた
ものである。The perspective view of FIG. 5 shows the second embodiment of the present invention, in which the pattern 1f is formed on the surface of the connecting piece 1 by stamping with a press.
従来の連結駒の製造は、ダイス引き、ロール引きによ
り行なっていたため、あらかじめ、表面に模様を付けて
おくことができなかったが、この発明においては、表面
に模様を付けてから、溝を設けることができる。Since the conventional connecting piece was manufactured by die drawing or roll drawing, it was not possible to form a pattern on the surface in advance, but in the present invention, the groove is formed after the pattern is formed on the surface. You can
以上説明したように、この発明に係わる、バンド用連
結駒の製造方法によれば、溝の加工前に、プレスによる
型打ちで、模様付ができるようになったため、複雑な形
状でかつ、商品価値の高いバンドを作ることができるよ
うになった。As described above, according to the method for manufacturing a band connecting piece according to the present invention, a pattern can be formed by stamping with a press before the groove is processed. You can now make a high band.
また従来のように、金属棒材のダイス引き、ロール引
きを必要としないため、幅広い種類の材料を使うことが
できるようになった。Further, unlike the conventional case, since it is not necessary to perform die drawing and roll drawing of a metal rod material, a wide variety of materials can be used.
更に、加工工程の途中で、硝酸液等にひたす必要がな
くなったため、加工工程を簡素化できるようになった。Furthermore, since it is no longer necessary to dip in a nitric acid solution or the like during the processing step, the processing step can be simplified.
