DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for manufacturing a ring as an accessory and a ring.

[0002]

2. Description of the Related Art Decorativeness is important for rings, but engagement rings and other memorable rings often have relatively simple designs such as Komaru and flat types.

By the way, when engraving a character on a ring, usually it is often put on the back side. The reason is that when engraved letters, these letters are composed of so-called linear grooves, and unless they are specially colored, they have the same color as the precious metal of the ring, which is a bullion, and are inconspicuous, Because there is no.

[0004]

However, in the case of a ring with a memorial, it is important to apply the memorial character or graphic on the outward surface of the ring and use it as a decoration to make the memorial character of the ring stand out. Therefore, it is desirable to increase the value as a unique thing and there are many desired directions, but coloring characters and figures with paint etc. gives a cheap impression and has noble metal The purity is impaired, which is not preferable.

However, drawing characters and figures by embedding other noble metals or shells using techniques such as inlaying is extremely time-consuming, and is particularly troublesome and inexpensive for small objects such as rings. It will rise in proportion.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned disadvantages of the prior art, and when characters and figures are applied to the outward surface of a ring, these characters and figures become conspicuous, which is suitable for constructing a decoration. A method of manufacturing a ring and a ring.

[0007]

In order to achieve the above object, the present invention provides a method for manufacturing a ring, which comprises the steps of: forming a precious metal rectangular plate which is to be a ring;
A character or figure is engraved with a groove having a depth of about 0.3 mm, the plate is bent into a ring with the surface of the character or figure facing outward, and the outward surface becomes a polyhedron with a diamond bite. The main point is that characters or figures are made to emerge in the cut polyhedron by cutting as described above, and that the diamond is a 180 ° diamond and that the polyhedron is a 60-plane cut face.

As the ring, a 60-faced polyhedron cut surface by a diamond is provided on the outward surface so as to form vertical stripes in the vertical width direction of the ring, and the bottom width is about 0.2 mm in the polyhedron cut surface. The gist is that the opening is formed by arranging characters or figures in a circumferential direction of the ring body with grooves of 120 ° and a depth of about 0.2 mm.

According to the present invention, a character or a figure is cut into a polyhedron with a diamond tool, and the characters or figures are arranged in such a cut polyhedron. Therefore, the brightness changes depending on the viewing angle like a mirror ball, and characters or figures can be made to appear on the outer surface of the ring, and the presence of the characters or figures stands out, and a large decorative effect can be obtained.

When a polygonal cut surface is first formed by mirror finishing and a character or figure is engraved thereon, there is a risk that the polyhedral cut surface may be erroneously damaged and the mirror finish may be lost. Since the present invention engraves characters and figures first and forms a polyhedral cut surface thereon, there is no such concern. In addition, the grooves constituting the characters and figures are slightly shaved when the polyhedron cut surface is formed, but are pre-engraved at a certain depth or more,
Almost no problem.

Since characters and figures are applied not in the state of a ring but in the state of a rectangular plate, work can be easily performed in a stable state.

Furthermore, since the polyhedron is a 60-sided cut face, the mirror surface of the vertical stripes in the vertical width direction is fine, and there is no hindrance in contrast with characters and figures, and the width of the vertical stripes is increased. The smoothness of the circular arc as the outer surface of the ring is not lost because it is not a continuation of a wide plane.

[0013]

Embodiments of the present invention will be described below in detail. FIG. 1 is an explanatory view showing one embodiment of a ring of the present invention, in which 2 indicates an outward surface of the ring 1.

According to the present invention, the outwardly facing surface 2 is provided with a unit cut surface 3 by mirror finishing which is cut with a 180 ° diamond bit.
a is continuous so as to form vertical stripes in the vertical width direction of the ring body.
A polyhedron cut surface 3 of a face was provided. In the figure, reference numeral 4 denotes a chamfered portion of the upper and lower edges of the ring.

In the polyhedron cut plane 3, a 0.
Characters 5 or figures engraved at a depth of about 2 mm were arranged side by side in the circumferential direction of the ring. In the illustrated example, the character 5 is a cursive alphabet and has continuity.

Next, a method for manufacturing a ring according to the present invention will be described. The engraving of the character 5 may be performed on the outer surface after forming a ring with a noble metal such as gold, platinum, silver or the like, but as shown in FIG. And engraved on the surface of the flat plate 6 at a depth of about 0.3 mm.

The letter 5 has a bottom width of about 0.2 mm and an opening formed by a 120 ° groove as shown in FIG.

Next, as shown in FIG. 3, the rectangular plate 6 is bent so that the character 5 comes to the outward surface 2, and the ends are brazed to form a ring as the ring 1.

Then, as shown in FIG. 4, a 60-sided face is cut with a 180 ° diamond tool. By this cutting, the outward surface 2 of the ring 1 is shaved by about 0.1 mm, and the rest becomes about 0.2 mm in depth. However, the required depth can be sufficiently secured.

Although the cut of the 60-hedron is not shown, the ring 1 is brought into contact with the diamond while slightly turning it, and the unit cut surfaces 3a are sequentially connected.
At the same time, the chamfered portions 4 on the upper and lower edges of the ring are formed for each unit cut surface 3a with the same mirror finish.

In the above embodiment, the polyhedron cut surface 3 is a 60-sided one, but the number is not limited to this number and can be changed. The same applies to the frequency of the byte, and the character 5 can be replaced with Japanese characters or figures.

[0022]

As described above, the method of manufacturing a ring and the ring according to the present invention can be applied to an outer surface of a ring such as a mirror ball whose brightness changes depending on the viewing angle when characters or figures are formed on the outward surface of the ring. The contrast between the character and the graphic provided on the outer surface thereof makes the character or graphic prominent, and is suitable for forming a decoration.
