All or part of the following steps are performed by a machine (ring manufacturing apparatus) or manually.

[Preparation steps of metal plate (step ST11)]

Prepare multiple metal plates of different materials.

In this embodiment, 15 metal plates are prepared.

As the material of the metal plate, platinum (Pt), gold (Au), silver (Ag), copper (Cu), brass, titanium (Ti), iron (Fe), nickel (Ni), stainless steel, and tantalum can be used. (Ta), or a mixture of these.

The plurality of metal plates are respectively composed of different materials, and the visually distinguishable properties such as the color or the degree of gloss are different. The thickness of the metal plate is about 0.1 mm to 1.0 mm. In addition, metal plates of different materials, As long as there are at least two types. In addition, two or more metal plates among the plurality of metal plates may be made of the same material.

[Steps before lamination (step ST12)]

Secondly, as a pretreatment before joining, sandpapers such as 600, 800, 1000, 1200, 1500, etc. are used to grind a plurality of metal plates, and then, as appropriate, polished with charcoal ( charcoal finishing) and very carefully finish the surface evenly.

[Lamination step (step ST13)]

Next, a plurality of metal plates are laminated, and the metal plates are bonded to each other to form a multilayer metal body having a plurality of metal layers laminated (an example of the plurality of metal plates obtained by the lamination of the present invention).

Here, the stacking order is determined in consideration of the final design feeling (feature pattern).

At this time, each of the metal plates is, for example, 0.05 mm to 0.2 mm, and the shape of the multilayer metal body is, for example, 1.0 mm × 40 mm to 2.0 mm × 40 mm to 60 mm × 60 mm to 60 mm × 80 mm.

[Joining step (step ST14)]

The metal plates are bonded to each other, for example, by tightly bonding the metal plates, and applying pressure to a temperature at which the plastic deformation of the metal plates does not occur as much as possible under a temperature condition below the melting point of the metal plates, and the diffusion bonding is performed. They are bonded by diffusion of atoms generated between the bonding surfaces of the metal plates.

Conditions for performing diffusion bonding are, for example, as described below. That is, heating and pressurization are performed at 500 ° C to 1200 ° C and 200 kgf / cm ² to 500 kgf / cm ² . In addition, joining of metal plates may be performed by soldering.

[Square rod-shaped processing step (step ST15)]

Next, after inspecting the details and removing the incompletely laminated portion, as shown in FIG. 9A, for example, a roller is subjected to a stretching process to become a square rod shape.

[Step of twisting (step ST16)]

Next, as shown in FIG. 9B, the torsion processing system performs a plurality of inversions of the table, back, table, and back.

The above-mentioned plural reversals are performed on the square rod that is forged, and the heating and annealing are repeated while paying attention to the lamination sequence, and the twisting process is performed carefully little by little. At this time, the twisting step, the cooling step, and the annealing step are sequentially repeated while heating.

[Square rod-shaped processing step (step ST17)]

Next, as shown in FIG. 9C, the member after the twisting process step is subjected to a stretching process using a roller to have a square rod shape.

In this embodiment, the reason why the shape of the cross section is smaller than that of the member obtained in step ST15 at this time is to adjust for the actual finishing size.

In addition, by processing into a square rod shape before the pattern formation, the pattern formation object can be formed into a flat surface, and the pattern can be easily formed.

[Cut out step (step ST18)]

Next, the square bar obtained in step ST17 is cut out to have only the capacity required to form a ring and a pendant.

[Pattern forming step (step ST19)]

Next, as shown in FIG. 10, a pattern of a predetermined pattern shape, such as a character, a mark, a figure, is formed on the surface side of a square bar.

The pattern is formed by carving with a chisel or a drill-like tool.

For example, after twisting is applied, a chisel or drill-like tool is used to sculpt down to more than half the depth of the laminate.

When engraving down to such a depth in a laminated layer having a thickness, the height difference will not be excessively formed when it is stretched to a flat surface by a roller, and the overall appearance or the pattern depending on the twisting process will be greatly affected. Actually, it is not a one-time engraving, but a square rod that has been subjected to torsion processing to a flat shape to a certain degree, and then engraving and stretching, and the steps of engraving and stretching are repeated dozens of times. Make a pattern.

This time, using a roller, the square bar material subjected to the twisting process is stretched to a thickness of about half or less.

[Extending step (step ST20)]

Next, as shown in FIG. 11, the square bar material having the pattern formed in step ST19 is extended in the longitudinal direction so as to have a predetermined thickness.

Specifically, for example, a square bar is inserted between two rollers provided at a predetermined interval so as to be rotatable, and the surface is extruded, whereby the metal body can be extended.

[Ring processing step (step ST21)]

After that, the metal plate stretched in step ST20 is processed into a ring shape to obtain a ring 21.

[Ring-off step (step ST22)]

As shown in FIG. 4 (A), a ring 21 is formed at a specified position in the width direction (for example, near the center position), and a part of the joint portion 25 is left along the circumferential direction and cut by a dividing line 23 to form a male ring.部 31 and 女 环 部 33.

At this time, when the width of the male ring portion 31 is made wider than that of the female ring portion 33, cutting is performed at a non-center position in the width direction in accordance with the width.

The size of the joint portion 25 is determined in accordance with the desired size of the convex portions 2 a and 3 a shown in FIG. 1.

[Bending step (step ST23)]

Then, as shown in FIGS. 4 (B) to 4 (E), the male ring portion 31 and the female ring portion 33 are folded only in a direction separated from each other with the joint portion 25 as the center. Bend a specified angle (for example, about 90 °). This angle may be other than 90 °.

[Slit formation step of joint portion (step ST24)]

According to the user's desire, the convex portions 2a, 3a which are the traces obtained from the joint portion 25 can be selected to have a larger "trace" and a smaller "no trace".

FIG. 6 (A) is a schematic diagram for explaining a method of forming a slit in a case where there are “traces”, and FIG. 6 (B) is a schematic diagram for explaining a method of forming a slit in a case where “no trace” is used.

As shown in FIG. 6 (A), in the case of “marking”, a slit 51 is formed on the boundary line 23 side (the side to be cut) of the joint portion 25. The slit 51 is formed using, for example, a fretsaw. By forming the slit, the width of the joint portion 25 is formed to be about 0.6 mm to 0.8 mm.

As shown in FIG. 6 (B), in the case of "no trace", slits 53 and 55 are formed from both the boundary 23 side (the side to be cut) of the joint portion 25 and the opposite side. The slit is formed using, for example, a wire saw. By forming this slit, the width of the joint portion 25 is formed to be about 0.7 mm to 0.9 mm.

[Measurement of the joint width (steps ST25 and ST26)]

As shown in FIG. 7, the width of the joint portion 25 after the slit is formed is measured with a measuring device.

In addition, as shown in FIG. 8, the probe tip of the measuring device is Is inserted deep inside the slit. Thereby, measurement accuracy can be improved.

As a result of the measurement, if the width of the joint portion 25 has reached a predetermined value, the process proceeds to step ST27, and if it has not reached the predetermined value, the process returns to step ST24 (step ST26).

[Cut Step (Step ST27)]

Then, the joint portion 25 is cut to obtain the male ring 2 and the female ring 3 shown in FIG. 1.

At this time, the position of the apex of the convex part which comprises the joint part 25 is cut | disconnected.

Thereby, as shown in FIG. 1, the male ring 2 is formed with the convex part 2a obtained by the joining part 25 and protrudes from the ring outer peripheral surface, and the female ring 3 is formed with the joining part 25 and obtained from the joining part 25. A convex portion 3a protruding from the outer peripheral surface of the ring.

After the cutting, as shown in FIG. 8, the shape of the traces of the convex portions 2 a and 3 a of the male ring 2 and the female ring 3 is measured using a measuring device 150 and processed as required.

Here, the convex portion 2a and the convex portion 3a are obtained by cutting the joint portion 25, and the male ring 2 and the female ring 3 can have a so-called appearance impression produced (made) by the same thing.

On the side surfaces adjacent to the convex portions 2a, 3a of the male ring 2 and the female ring 3, recesses having a size corresponding to the volume of the convex portions 2a, 3a are formed.
