Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for producing a decorative cut ring with a colored cotton pattern made of a plurality of types of precious metals with different colors and alloys thereof.

Conventionally, decorative cut rings are generally made by forming band-shaped materials with various shapes such as square, step circular, or semicircular cross sections from precious metal or precious metal alloy materials through normal plastic deformation processing, and then forming them into bands. After cutting out a strip of a predetermined length from the strip material, it is bent into a ring shape, and the mating parts are joined to form a ring body. It is manufactured by the main process of applying a cut pattern.

However, in the conventional decorative cut ring mentioned above,
As mentioned above, since the ring body is made of a single material, it has little variation in color tone, so no matter how much effort is put into the cut pattern on its surface, the design cannot be improved. Since there was not much change in his life, he was unable to break free from the monotony and was prone to getting bored easily.

From the above-mentioned viewpoint, the present invention provides a method for manufacturing a decorative cut ring that has a different color tone and is attractive in terms of design. A plurality of different types of materials are arbitrarily combined, overlaid, and joined together using a normal cladding method to form a laminated plate material, and then the laminated plate material is crossed at an arbitrary angle with respect to each mating surface of the above-mentioned materials. After cutting to a predetermined width from the direction of the material and separating the composite piece in which the cuts of the material form layers on the cut surface, the composite piece is cut with a low food die, a kya IJ bar roll, a Turk's head, a die, etc. A strip material of an arbitrary cross-sectional shape with a color striped pattern based on the arrangement of the material is formed by plastic deformation processing using ``A ring body is formed by bending and joining the mating parts by brazing, etc., and finally the surface of the ring body is machine-cut using a cutting machine, etc., or hand-carved to create an arbitrary cut pattern. The main process consists of forming a decorative cut ring, which has a colored striped pattern made of multiple types of precious metals and their alloys with different tones, and in which the cut pattern stands out even more due to the colored striped pattern. Next, the method of the present invention will be explained by way of examples with reference to the drawings.

Example 1 A yellow-toned gold alloy (Au
:75%, Ag:8%, Cu:17%, weight%, below %
means weight %) plate materials: 2 sheets and white-toned gold alloy (Au: 75%, Pd: 20%, Ag: 5%) sheet materials:
Prepare one sheet, stack these plate materials alternately, and hot roll this under the conditions of rolling temperature: 75,000 and reduction rate: 50% to obtain a shape of width 52.5 side x length 130 willow x thickness. Sa5. A composite part in which a clad-jointed laminated plate material with the dimensions of the opposite side is cut, and the cut sides of the materials form a layer on the cut surface, by cutting the laminated plate material five widths from the end of the laminated plate material, perpendicular to the mating surface. A piece was separated.

Next, the composite piece was subjected to drawing processing (plastic deformation processing) using a Turk's head, so that the cross section shown in the perspective view in FIG. , and a strip material having a color striped pattern based on the arrangement of the above materials was molded. Subsequently, a strip piece having a length of 55 ribs was cut out from the strip material, subjected to a bending process, and the joint portion was brazed using 18-karat gold solder to form the piece shown in the perspective view in Fig. 2. The ring body shown was molded.
Finally, a cutting pattern was applied to the surface of the ring body using a cutting machine to produce a decorative cut ring shown in a perspective view in FIG. 3. The resulting cut ring is
The yellow and white color stripes provide a wide range of color tones, and the color stripes make the cut pattern stand out even more, giving it an innovative design.

Example 2 As a plate-shaped material, gold alloy (A
u: 58.5%, Ag: 27.75%, Cu: 13.7
5%) plate material and a gold alloy (Au: mottled.
5%, Ag: 6.0%, Cu: 35.5%) plate material, 1 yen gold solder was used as the brazing material, and a roller die was applied as the plastic deformation processing means to achieve a maximum width of 5. 5 and 5, respectively, under the same conditions as in Example 1 above, except that a crescent-shaped strip material having the dimensions of rib x maximum thickness of 4 mm and shown in a perspective view in FIG. 4 was formed. Ring body shown in perspective view in Figure 6 (see Figure 5)
and a cut ring (Fig. 6) was manufactured.

The above-mentioned cut ring had a cut pattern in which the red tone of the base appeared in places, so it matched with the yellow tone of the upper part, giving it a rich variety of colors.

Example 3 As a plate material, Au: 75%, Cu: 17%, Ag:
A yellow-toned 18-karat gold alloy plate with a composition of 8%, a white-toned platinum alloy plate with a composition of 95% Pt, 5% Cu, and 75% Au, 25% Cu.
%, and a drawing die was used as a plastic deformation processing means to produce a material with a width of 5 sides x center thickness of 1 rib x both sides of thickness of 0.7 mm. 8 and 9, respectively, under the same conditions as in Example 1, except that a strip having the dimensions of the ribs and having the shape shown in the perspective view in FIG. 7 was formed. A ring body and a cut ring were manufactured.

The resulting cut ring was ``extremely beautiful in both design and color tone, with a cut pattern that matched the yellow, white, and red color stripes.''

In addition, in the above example, cases were described in which two and three types of plate-shaped materials were used, but it is also possible to use four or more types of plate-shaped materials, and in this case, the color tone will be better. Of course, there will be a lot of variety.

As described above, according to the method of the present invention, it is possible to manufacture a decorative cut ring having a colored striped pattern made of a plurality of kinds of precious metals with different tones and their alloys through a simple process and at a low cost. Rather, the color striped pattern makes it possible to create an innovative product with a wide variety of colors and designs.
