て押圧かしめ加工することを特徴とするものである。(Structure) The technical means of the present invention for solving the above-mentioned problems includes a cylindrical body, a spacer held inside the cylindrical body, and a pair of jewelry stored at both ends of the cylindrical body with the spacer sandwiched between them. In caulking the end of the cylindrical body of the decorative part around the jewelry, the jewelry is inserted through the upper opening of the cylindrical body, and the edge of the opening is rotated with a caulking punch. It is characterized by press caulking.
（作用）
上記のように構成された本発明の装飾用部品の製造方法
によれば、回転するかしめ用パンチにて押圧かしめ加工

率よくかしめ加工され、筒状本体が外側にひろがり変形
することなく、安定したかしめ止めができるものである
。(Function) According to the method for manufacturing decorative parts of the present invention configured as described above, the rotating caulking punch performs the press caulking process, so the caulking force is dispersed in the direction of the periphery of the opening, thereby efficiently It is caulked and can be stably caulked without the cylindrical body expanding outward and deforming.
（実施例） 以下に実施例について説明する。(Example) Examples will be described below.
第１図ａに示す如く、スペーサ−１を内周に固定した筒
状本体２を、かしめ用の治具３のスペーサ−１と等しい
外径で、宝石類４の収納スペースと等しい高さの突起５
外周トに嵌め込み、更に筒状本体２の外径より若干広い
内径を有したホルダ６を嵌め込み、セットして、上端開
口部から宝石類４を嵌め込んで、開口部端縁を６００ｒ
ｐｍにて回転する半球状凹部を設けたかしめ用パンチ７
にてかしめ加工し、つぎに第１図１〕に示す如く筒状本
体２をひっくり返し、その加工済みの端部を凹部８を設
けた治具９内に嵌め込んで、更に前記ホルダー６を嵌め

んで、開口部端縁を６００ｒｐｍにて回転する前記かし
め用パンチ７にてかしめ加工して、両端に宝石類４．４
′を有した装飾用部品を作った。As shown in FIG. 1a, a cylindrical body 2 with a spacer 1 fixed to its inner periphery has an outer diameter equal to that of the spacer 1 of the caulking jig 3 and a height equal to the storage space for the jewelry 4. Protrusion 5
Fit the holder 6, which has an inner diameter slightly wider than the outer diameter of the cylindrical body 2, into the outer periphery, set it, and fit the jewelry 4 from the upper opening to tighten the edge of the opening by 600r.
Caulking punch 7 provided with a hemispherical recess that rotates at pm
Next, the cylindrical body 2 is turned over as shown in FIG. After fitting and setting, the jewelry 4' is fitted from the upper end opening, and the edge of the opening is caulked with the caulking punch 7 rotating at 600 rpm, and the jewelry 4.4 is attached to both ends.
′ was made.
一方、従来例として実施例におけるかしめ用パンチ７′
は回転せずに、また、ホルダー６を用いずにかしめ加工
し、他は同様にして装飾用部品を作った。On the other hand, as a conventional example, the caulking punch 7' in the embodiment is
A decorative part was made in the same manner except that it was caulked without rotating or using the holder 6.
然して、従来例においては１００ケ中３１個が筒状本体
がひろがり変形し、スペーサーとの間にすき間ができて
いたので手直しが必要であったのに対し、実施例におい
ては皆無であった。However, in 31 out of 100 conventional examples, the cylindrical body was expanded and deformed, and a gap was created between the cylindrical body and the spacer, requiring modification, whereas in the example, there were none.
なお、実施例においては回転するかしめ用パンチにより
かしめ面は光沢のある鏡面となり装飾的仕」二がりの優
れたものであった。さらに従来例よりも小さい押圧力で
かしめ加工ができた。In the examples, the rotating caulking punch gave the caulked surface a glossy mirror surface, giving an excellent decorative finish. Furthermore, caulking was possible with a smaller pressing force than in the conventional example.
（発明の効果）
以」二のように本発明の装飾用部品の製造方法によれば
、回転するかしめ用パンチにて押圧かしめ加工するので
、かしめ力は開口部周縁方向に分散され、効率良くかし
め加工され、筒状本体が外側にひろがり変形することな
く、安定したかしめ止めができるという優れた効果を有
するものである。(Effects of the Invention) As described in Section 2 below, according to the method for manufacturing decorative parts of the present invention, since the pressing caulking process is performed using a rotating caulking punch, the caulking force is dispersed in the direction of the periphery of the opening, resulting in efficient caulking. It has the excellent effect of being able to be stably caulked without causing the cylindrical body to spread outward and deform.
また、かしめ面が光沢のある鏡面となり、また小さい押
圧力にてかしめ加工ができる等の効果も有するものであ
る。Further, the caulked surface becomes a glossy mirror surface, and the caulking process can be performed with a small pressing force.
