Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing a colorful decorative cut chain made of a plurality of kinds of precious metals of different colors and alloys thereof.

Conventionally, decorative cut chains, such as cut neck chains and cut bracelets, are generally made from precious metals or precious metal alloy materials into various shapes, such as circular, alternating, or rectangular cross-sections, by ordinary plastic deformation processing. The main process is to form a wire material with It was manufactured.

However, in the conventional decorative cut chain, since the cut pieces are made of a single material as described above,
There is no choice but to create a piece with little variation in color tone. Therefore, no matter how much effort is put into cut patterns or combinations of two or more pieces with different color tones, the design will not change much. Because of the lack of fun, I found it difficult to break away from the monotony and tended to get bored easily.

From the above-mentioned viewpoints, the present invention provides a method for manufacturing a decorative cut chain that has a novel design with a change in color tone. Multiple types of materials with different color tones are arbitrarily combined, overlapped, and bonded together using a normal cladding method to form a laminated board, and then the laminated board is arbitrarily applied to each mating surface of the above materials. After cutting at a predetermined width from directions crossing at an angle of , and separating a composite piece in which the cuts of the material form layers on the cut surface, the composite piece is cut with a roller die, caliber roll, Turk's head, or Plastic deformation using a die or the like is performed to form a wire material with an arbitrary cross-sectional shape and multiple color tones based on the arrangement of the materials, and then a cutting machine or the like is used to cut the wire material into an arbitrary shape. The main process is to apply a cut pattern, cut to a predetermined length, and finally chain the resulting cut pieces together using ring pieces or komochi silver. The present invention is characterized by manufacturing a decorative cut chain which has a rich variety of colors due to precious metals and their alloys, and whose cut patterns match the rich variety of colors and make the cut pattern even more attractive.

Next, the method of the present invention will be explained by way of examples with reference to the drawings.

Examples The plate-shaped materials were yellowish gold alloys (5% Au, 17% Cu, 8% Ag), each having dimensions of 50 mm wide x 85 mm long x 4 mm thick.

weight% (hereinafter % means weight%) plate material and a gold alloy with a white color tone (Au near 5%, Pd: 20%, Ag
: 5%) plate material and a gold alloy plate material with a reddish tone (Au near 5%, Cu: 25%) plate material, and these plate materials were prepared.
Layering the white-colored gold alloy plate materials in between,
This was hot rolled at a rolling temperature of 750°C and a rolling reduction of 50% to a width of 527ILm x length of 170im x thickness of 6mm.
A composite piece is obtained by cutting a clad-bonded laminated plate with a width of 6 mrn from the end of the laminated plate perpendicularly to the mating surface to create a composite piece in which the cuts of the material form a layer on the cut surface. was fractionated.

Next, the composite piece is subjected to plastic deformation processing by die drawing to produce yellow, white, and Linear materials with three different shades of red were molded.

Subsequently, the wire material is subjected to a cutting machine, and then cut with a cutting tool to obtain a wire material with a cut pattern shown in the cross-sectional view in FIG. The length is 15 m, which is also shown in the cross-sectional view in Figure 3.
It was made into a cut piece of m.

Finally, the cut pieces were joined together with a holder to form a cut chain of a predetermined length.

The resulting cut chain is not only extremely colorful, with the three tones of yellow, white, and red well-matched, but also has a cut pattern due to this rich variety of colors. It looked even better and had an innovative design.

In addition, in the above example, a case was described in which plate-shaped materials having three different color tones were used, but two or four different color tones were used.
The same process can be carried out even if more than one type of plate-like material is used, and the more different types of plate-like materials with different tones are used, the more the color scheme can be varied, and the more aesthetically pleasing it is. Of course, it will be.

As described above, according to the method of the present invention, the material has a rich color tone brought about by a plurality of kinds of precious metals with different color tones and their alloys, and has a rich variety in color and design due to the color tone. A novel decorative cut chain,
It can be manufactured with a simple process and at low cost.
