Abstract

PURPOSE:To combine colors and patterns and to obtain ornamental articles matching with the shape by forming a clad wire consisting of an Au alloy and Pt alloy to a required shape and inscribing patterns onto the surface thereof to expose part of the core material. CONSTITUTION:A clad wire 3 consisting of either of the Au alloy and Pt alloy having different colors as a core material 2 and the other as a sheath metal 1 is drawn to form a half round wire 4. After the wire 4 is worked to the required shape 5, the patterns 6 are properly inscribed on the outside surface to expose partly the material 2. The ornamental article 5' combined with the colors and patterns is thus obtd.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a method for manufacturing decorative articles such as rings, bracelets, necklaces, earrings, and parts thereof.

(Problems to be Solved by the Invention) Conventionally, the above-mentioned decorative items have been made of a single precious metal or precious metal alloy, so while they can be made with a variety of shapes, they are not uniform in color. Since it is a single color, there is little variation and it wears out easily.

For this reason, decorative items simply made by bonding precious metals or precious metal alloys have been used recently, but since the trajectory of the border lines of different colors is a monotonous combination, it is possible to obtain decorative items that match the shape and pattern. I couldn't.

(Object of the Invention) The present invention was made in view of the above circumstances, and it is an object of the present invention to provide a method for making decorative articles that combine colors and patterns to match shapes.

(Means for Solving the Problems) The method for manufacturing decorative articles of the present invention includes Au alloys of different colors,
After processing a clad wire into a desired shape with one of the Pt alloys as a core material and the other as a sheath metal, a suitable pattern is engraved on the surface to expose a part of the core material. This is a characteristic feature.

(Example) An example of the method for manufacturing a decorative article according to the present invention will be described below with reference to the drawings in the case of manufacturing a ring. As shown in Fig. 1, a round vibrator 1 made of yellow 18-karat gold (Au-Ag11%-Cu14%) has an outer diameter of 6.2 mm, a wall thickness of 0.7 mm, and a length of 50 cm.As shown in Fig. 2, it has a diameter of 4 mm. 8, insert a white Pt-PdlO% round wire 2 with a length of 50 cm, and connect it to 17
As shown in Figure 3, the diameter is 2.8 mm and the length is 2 mm.
．． An Au alloy and Pt alloy clad wire 3 with a thickness of 0.3 n+ and a thickness of 0.3 n+ is made, and then this clad wire 3 is drawn as shown in FIG. 4 to have a cross-sectional width of 3 inches and a cross-sectional height of 1.4 m.
Make 5 cranes' Komaru line 4.

The round wire 4, which is the material for a ring made in this way, is cut to a required length, bent into a circle, and joined at both ends to make a ring 5 as shown in Fig. 5. After this, a diamond cut 6 is made on the arcuate outer surface of the ring 5, as shown in FIG. 6, for example, to expose a portion of the Pt alloy core material to form a ring 5' with a combination of colors and patterns.

In this way, ring 5' becomes an unprecedentedly gorgeous and elegant ring with colors and patterns that match the shape.

Note that the pattern engraved on the outer surface of the arc of the ring 5 is not limited to diamond cut.

The above example is for making a ring 5', but when making presslets, necklaces, earrings, or their parts, the cladding wire of Au alloy and Pt alloy is not only processed into a round wire, but also an appropriate method is used. It shall be molded into the required external shape and cross-sectional shape by means of means. Furthermore, when making a desired decorative article using the cladding wire having the desired external shape and cross-sectional shape, the pattern engraved on the outer covering metal is not particularly limited.

(Effects of the Invention) As can be seen from the above explanation, the method for manufacturing decorative articles of the present invention involves making an Au alloy and Pt alloy clad wire, and then processing the clad wire appropriately to form it into a desired shape. Appropriate patterns are engraved on the surface to expose a part of the core material, so colors and patterns are combined to match the shape of the ornaments to be processed, creating unprecedentedly gorgeous and elegant rings, bracelets, and necklaces. , earrings, and their parts can be easily obtained.
