【発明の詳細な説明】
本発明は環状体封着型貴金属クラツド素材に関
する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a ring-sealed noble metal clad material.
ネツクレス，ブレスレツトおよび指輪等のチエ
ーンやリングの素材として近時、第１図に示すよ
うな素材がある。これは母材１の中心に母材より

量産ができるようになつてきた。 Recently, materials such as those shown in FIG. 1 are available as materials for chains and rings such as necklaces, bracelets, and rings. This is a ring-shaped material using a material in which a brazing material 2 such as Ag wax or Shinchi Yuro is placed in the center of the base material 1 and the brazing material is 1 to 2 carats lower in quality to lower the melting point than the base material. Mechanical mass production became possible as connections were made to machines.
しかし、上記の素材によると、ろう材２が切断
面の中心にあるため、接続加工の巧拙の影響をま
ともに受けやすく、第２図Ａに示す如く接続個所
である橋絡部３が細くなつたり、第２図Ｂに示す
如く局部的にろうが流れたり、または第２図Ｃに
示す如く内側か外側にろうがはみ出したりしてし
まうことが多々あり、接合強度の低下は勿論のこ
と仕上り外観が悪いという欠点が生じ易い。 However, according to the above material, since the brazing filler metal 2 is located at the center of the cut surface, it is easily affected by the skill of the connection process, and as shown in Figure 2A, the bridge portion 3 that is the connection point becomes thin. In many cases, the solder flows locally as shown in Figure 2B, or the solder protrudes from the inside or outside as shown in Figure 2C, which not only reduces the joint strength but also reduces the quality of the finish. This tends to have the disadvantage of poor appearance.
本発明は上記の欠点を解決することを目的と
し、ろう材を母材の外周近くに配置することによ
り接続部の封着効果が高く接合強度の高い製品と
することができるろう入り貴金属素材とすること
を特徴とする。 The purpose of the present invention is to solve the above-mentioned drawbacks, and the present invention is a brazed precious metal material that can provide a product with a high sealing effect at the connection part and high bonding strength by arranging the brazing material near the outer periphery of the base metal. It is characterized by
以下本発明の実施例を図面に従つて説明する。 Embodiments of the present invention will be described below with reference to the drawings.
第３図Ａ，Ｂは本発明の一実施例を示し、K12

して所定の寸法の一次複合材６を作る。 Figures 3A and 3B show an embodiment of the present invention, K12
On the outer periphery of the core material 4 made of (50Au-Ag-Cu),
A K9 (37.5Au-Ag-Cu-Zu) pipe-processed brazing filler metal 5 is fitted and tightly bonded, and heat treatment and wire drawing are repeated to produce a primary composite material 6 of a predetermined size.
次に、上記中心素材６と同一素材に一次複合材
６の外径と同一寸法の径の穴をあけて外被材７を
作り、この外被材７の穴に第３図Ｂに示す如く一

The primary composite material 6 is inserted and fitted, and heat treatment and wire drawing are repeated to complete the composite material.

The core material 8 consists of (75Au-10Ag-Cu), and an alloy of the same grade and lower melting point (75Au-9Ag-Cu-Cd)
The brazing filler metal 9, which has undergone pipe processing, is fitted tightly,
Furthermore, a thick-walled pipe 10 having the same composition as the core material 8 is fitted around its outer periphery to form a billet consisting of three layers, and this billet is hot extruded into a material, which is then subjected to wire drawing and annealing to obtain the desired shape. Finished in material with dimensions of.

ができる。 In addition, in each of the above embodiments, the cross-sectional shape of the material can be not only circular but also square or other irregular shapes, and the brazing filler metal charged inside can also be circular, square circular, or irregularly shaped. Furthermore, the annular shape does not necessarily have to be continuous as shown in FIGS. 5A, B, and C. In this case, the brazing material can be manufactured by sandwiching and arranging wire rods similar to the base material.

れる効果を有する。 According to the present invention, by arranging the brazing filler metal in a ring shape near the outer periphery of the material instead of at the center, the flow of the solder on the connection surface is good and the edges of the connection point can be evenly surrounded. If the bonding distance is narrow as shown in FIG. 6A, the entire surface of the bonding surface can be bonded, or if the bonding distance is wide as shown in FIG. It has the effect of providing high sealing properties and a significantly superior external finish.
