Description

本発明は、指輪等の身飾品の製造方法に関し、詳しくは外側リング体と内側リング体からなる空洞部を設けた身飾品の製造方法に関する。   The present invention relates to a method for manufacturing a jewelry such as a ring, and more particularly, to a method for manufacturing a jewelry provided with a hollow portion composed of an outer ring body and an inner ring body.

プラチナや金等の高価な貴金属によって作られる指輪等の身飾品は高価なプラチナや金等の貴金属を使用するため価格が高くなる。
そこで、このような指輪等の身飾品の価格を抑えるために、身飾品の内部を空洞にして貴金属の使用量を少なくすることにより価格を抑えた空洞部が設けられた身飾品が提案されている。
ところで、従来、空洞部を設けた指輪を製造する場合は、指輪を構成する外側リング体と内側リング体をそれぞれ金型で形成し、外側リング体に内側リング体を挿入して外側リング体と内側リング体をロウヅケして外側リング体と内側リング体を一体にして製造している。
しかし、上記製造方法では指輪の形状やサイズ毎に外側リング体を製造する金型と内側リング体を製造する金型を用意しなければならないため、金型の製造費用が高くなり、製品の価格に転化されるという不具合がある。
また、金型で外側リング体と内側リング体を製造して指輪をする場合は大量生産には向いているが、多品種、小ロットの指輪を生産する場合には不向きである。 Jewelry and other jewelry made of expensive precious metals such as platinum and gold use expensive precious metals such as platinum and gold, and therefore are expensive.
Therefore, in order to suppress the price of such jewelry such as a ring, there has been proposed a jewelry provided with a hollow portion with a reduced price by reducing the amount of precious metal used by hollowing out the interior of the jewelry. Yes.
By the way, conventionally, when manufacturing a ring having a hollow portion, an outer ring body and an inner ring body constituting the ring are respectively formed by a mold, and the inner ring body is inserted into the outer ring body to The inner ring body is brazed to manufacture the outer ring body and the inner ring body integrally.
However, in the above manufacturing method, it is necessary to prepare a mold for manufacturing the outer ring body and a mold for manufacturing the inner ring body for each ring shape and size, which increases the manufacturing cost of the mold and increases the price of the product. There is a problem that it is converted to.
In addition, when an outer ring body and an inner ring body are manufactured with a mold and a ring is produced, it is suitable for mass production, but is not suitable for production of rings of various varieties and small lots.

本発明は、上記事実に鑑みなされたものであり、製造費用を抑えることにより製品価格を抑えることができると共に多品種、小ロットの身飾品の製造にも適した外側リング体と内側リング体からなる空洞部を設けた身飾品の製造方法を提供するものである。   The present invention has been made in view of the above-mentioned facts, and it is possible to suppress the product cost by suppressing the manufacturing cost, and from the outer ring body and the inner ring body suitable for manufacturing a variety of small-lot jewelry.

なお、空洞部を設けた指輪１０の内部には空洞部３２が形成されているので、使用するプラチナの使用量を抑えることができるので、この点においても製品価格を抑えることができる。 1 to 5 show an embodiment of a method for manufacturing a garment having a hollow portion formed of an outer ring body and an inner ring body according to the present invention. In this embodiment, a case where a ring as an accessory is manufactured will be described as an example.
When manufacturing the ring 10 provided with the hollow portion according to the present invention shown in FIGS. 1 and 2, first, the cylindrical outer ring is manufactured to form the outer ring body 12 (see FIG. 1) as shown in FIG. A cylindrical inner ring manufacturing body 18 for preparing the body 14 and the inner ring body 16 (see FIG. 1) is prepared. The width dimension W1 of the outer ring manufacturing body 14 is set slightly smaller than the width dimension W2 of the inner ring manufacturing body 18. The outer ring manufacturing body 14 and the inner ring manufacturing body 18 are both made of precious metal platinum.
3 and 4, the intermediate portion of the inner peripheral surface 14A of the outer ring manufacturing body 14 is cut with a lathe (not shown), and a first recess is formed in the intermediate portion of the inner peripheral surface 14A. 20 is formed. Thus, first flange portions 22 and 22 are formed at both end portions of the inner peripheral surface 14A of the outer ring manufacturing body 14. Further, the outer peripheral surface 14B of the outer ring manufacturing body 14 is cut with a lathe to form a design in which the intermediate portion is raised.
Thereby, the outer ring body 12 as shown in FIG. 4 is manufactured from the outer ring manufacturing body 14.
3 and 4, the intermediate portion of the outer peripheral surface 18A of the inner ring manufacturing body 18 is cut by a lathe (not shown), and the second recess 24 is formed in the intermediate portion of the outer peripheral surface 18A. Form. As a result, second flange portions 26 and 26 are formed at both ends of the outer peripheral surface 18A of the inner ring manufacturing body 18. The inner ring body 16 is manufactured from the inner ring manufacturing body 18 by forming the locking step portions 28 and 28 (see FIG. 2) inside the second flange portions 26 and 26, respectively.
Then, as shown in FIG. 5, the inner ring body 16 is inserted into the outer ring body 12, the tapered pressing shaft 30 is inserted into the inner ring body 16, and the pressing shaft 30 is pressed by a press machine (not shown). Pressure is applied to the end face 30A.
Then, the first flange portions 22 and 22 of the outer ring body 12 are locked to the locking step portions 28 of the second flange portions 26 and 26 of the inner ring body 16 and the second flange portions 26 and 26 are the first flanges. The inner ring body 16 is crimped to the outer ring body 12 with the portions 22 and 22 being sandwiched, and a cavity 32 is formed between the outer ring body 12 and the inner ring body 16.
Thereby, manufacture of the ring 10 provided with the hollow portion shown in FIGS. 1 and 2 is completed.
Therefore, since the present invention manufactures the outer ring body 12 and the inner ring body 16 without using a mold, the product price can be suppressed by suppressing the manufacturing price of the ring 10 provided with the hollow portion as the product.
Further, according to the present invention, the outer ring manufacturing body 14 is cut to manufacture the outer ring body 12, and the inner ring manufacturing body 18 is cut to manufacture the inner ring body 16. Therefore, the manufacture of multi-variety and small lots of accessories is possible. Suitable for
In addition, since the hollow part 32 is formed in the inside of the ring 10 provided with the hollow part, the amount of platinum to be used can be suppressed, so that the product price can also be reduced in this respect.

なお、実施例では身飾品として指輪を製造する場合を例にして説明したが、身飾品は指輪に限定されるものではなく、例えばバングル等、他の身飾品を製造してもよいことは勿論である。
また、実施例では前記外側リング製造体１４の外周面１４Ｂを旋盤で切削して外側リング体１２の外周面の中間部が盛り上がるような意匠を外側リング体１２に形成したが、前記外側リング体１２の外周面の意匠は他の形状、模様等でもよいし、あるいは全く意匠を施さなくてもよいことは勿論である。
なお、実施例では前記外側リング製造体１４及び前記内側リング製造体１８を切削して肉厚が薄くなるようにしたが、前記外側リング製造体１４及び前記内側リング製造体１８の肉厚は実施例よりも薄くても厚くてもよいことは勿論である。 In addition, although the example demonstrated the case where a ring was manufactured as an ornament, the ornament is not limited to a ring, For example, you may manufacture other ornaments, such as a bangle, for example. It is.
In the embodiment, the outer ring body 14 is cut with a lathe to form a design on the outer ring body 12 so that the middle portion of the outer ring surface 12 is raised. Needless to say, the design of the outer peripheral surface of 12 may have other shapes, patterns, or the like, or no design at all.
In the embodiment, the outer ring manufacturing body 14 and the inner ring manufacturing body 18 are cut to reduce the wall thickness. However, the outer ring manufacturing body 14 and the inner ring manufacturing body 18 are not changed in thickness. Of course, it may be thinner or thicker than the example.
