【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.
ネクツレス、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。これは貴金属の母材１の中心に
その母材１よりも融点の低い低カラツト品位のろ
う材もしくはAgろう材２を入れた素材を用いて
リング状に接続することが行なわれるようになつ
て機械的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 has come to be done by using a material in which a low carat grade brazing filler metal or Ag brazing filler metal 2 with a melting point lower than that of the base metal 1 is placed in the center of a noble metal base material 1 to form a ring-shaped connection. Mechanical mass production has become possible.
しかし、上記素材によると、ろう材２が切断面
の中心にあるために、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
と仕上り外観も良くない欠点がある。 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. There is also a drawback that the appearance is not good.
一方、卑金属の外周に貴金属をクラツドした貴
金属クラツド線材がネツクレスやブレスレツト等
に実用化されなかつた大きな理由はクラツド線材
の接続不完全による接続断面の露出した卑金属の
腐食や変色が進行して実用性と美観を損うことに
なることにある。 On the other hand, the main reason why precious metal clad wire rods, in which precious metals are clad around the outer periphery of base metals, have not been put to practical use in necklaces, bracelets, etc. is that due to incomplete connection of the clad wire rods, corrosion and discoloration of the exposed base metals at the connected cross section progress, making it impractical. This can lead to deterioration of the aesthetic appearance.
そこで、本発明は上記の欠点を解決することを
目的とし、貴金属をクラツドした卑金属母材の外
周にろう材を配置することにより接続部の封着効
果が高く接続断面の露出が生ずることがなくしか
も接続強度が高い素材としたことを特徴とする。 Therefore, the present invention aims to solve the above-mentioned drawbacks, and by arranging a brazing filler metal around the outer periphery of a base metal base material clad with a noble metal, the sealing effect of the connection part is high and the connection cross section is not exposed. Moreover, it is characterized by being made of a material with high connection strength.
以下に本発明の実施例を図面に従つて説明す

のパイプを複合してクラツド材とする。 Figures 3A and 3B show an embodiment of the present invention, in which a thick-walled pipe of BAg-8 (72Ag-Cu), which accounts for 5% of the total area, is brazed around the outer circumference of a round bar 4 made of Cypronixel (70Cu-Ni). Composite material 5 and K18 (75Au-10Ag-Cu) as outer material 6 on the outermost periphery.
Composite pipes to make clad material.

径に仕上げる。 Next, as shown in Fig. 4C, BAg-1A (50Ag-15.5Cu-16.5Zn-18Cd) is applied to the same general nickel silver round bar 10 as above to a thickness of 5% of the total area of the finished product. The pipe is composited as a brazing material 11 to form a second composite material 12, which is finished to have the same diameter as the hole in the first composite material 9.
そこで第４図Ｄに示す如く第２複合材１２を第
１複合材９の穴に挿入させて熱処理および伸線を
繰返して線状の素材に仕上げる。 Therefore, as shown in FIG. 4D, the second composite material 12 is inserted into the hole of the first composite material 9, and heat treatment and wire drawing are repeated to finish it into a linear material.

ことができる。 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 shapes do not necessarily have to be continuous as shown in FIGS. 5A, B, and C. In this case, it can be manufactured by arranging the brazing material and the same wire rods as the base material.

果を有する。 According to the present invention described above, by arranging the brazing material in a ring shape near the outer periphery rather than at the center of the condition, the solder flows well on the connection surface and the edges of the connection point can be evenly surrounded. , as shown in Figure 6A, in the case of narrowing the joint interval, the entire joint surface, or
As shown in Figure 6B, when the bonding distance is wide, the connection can be made in a hollow shape so as to surround the outer periphery, and because the sealing properties of the connection part are high, the cross section of the base metal, which is the base metal, is not exposed. This has the effect that corrosion and discoloration will not occur and the external finish will be very good.
