Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a method for manufacturing a decorative metal composite plate in which a pattern is expressed using metal materials of different tones.

Generally, watch bands, bracelets, lighters, brooches, pendants, buckles, fountain pens,
Clad materials, which are made by bonding different metals together, are often used in the production of accessories such as cigarette cases, tie pins, and cufflinks, decorative items, and various crafts.

[Prior art and its problems]

Conventionally, many methods have been used to manufacture these clad materials, such as forge welding, which metallurgically joins metal surfaces, roll pressure welding, explosion bonding, and extrusion methods. In all of these bonding methods, the amount of deformation of the metal material due to the heating and compression process during bonding is extremely large, so it is not only difficult to form regular beautiful patterns, but also the number of layers that can be bonded is limited. 2 at most
The maximum number of layers was ~5, and even if something resembling a pattern could be made, it was extremely monotonous.

In order to overcome the above-mentioned drawbacks, the present applicant
We have previously proposed a method for manufacturing striped metal plates (Japanese Patent Laid-Open No. 55-30326), but the patterns obtained by this method are limited to striped patterns; metal composites with other highly decorative patterns can also be produced. At present, a practical method for manufacturing plates is still unknown.

[Research purpose]

Therefore, from the above-mentioned viewpoint, the present inventors
We conducted a variety of research to make the patterns of metal composite plates, which are used as materials for accessories, ornaments, and various crafts, more varied, as well as to make them regular and beautiful.

[Findings based on research]

As a result, a laminated material is produced in which a plurality of single-layer metal plates having a striped pattern are stacked and joined together so that at least one of the end faces of the metal material forms a predetermined pattern, or A prismatic material in which a plurality of rectangular metal wires of different colors are stacked and joined together so that at least one of the end surfaces of the rectangular wires forms a predetermined pattern; By cutting the metal composite plate into a predetermined width and separating the metal plate in which the cut surface of the laminated material or prismatic material forms a pattern derived from the predetermined pattern, various patterns can be applied to the surface of the metal composite plate. It has been found that patterns can be formed, and if diffusion welding is used to join the metal plates and square wires, it is possible to join a large number of plates or square wires without causing deformation of the metal material.

[Components of the invention]

Therefore, the present invention has been made based on the above-mentioned knowledge, and provides a method for manufacturing a decorative metal composite plate in which a pattern is formed on the surface of a plurality of metal materials having different tones. A first laminated material, which is made by stacking a plurality of metal plates of different types on top of each other and joining them together by diffusion welding, intersects at an arbitrary angle with each mating surface of the metal plates. Cut to a specified width from the direction,
Separating a first metal plate in which the cuts of the first laminated material form a layer on the cut surface, and then at least one of the end surfaces of each material metal plate that appeared on the cut surface of the first metal plate. The first metal plates are overlapped and joined together by diffusion welding so that the end surfaces of the materials form a predetermined pattern. A second metal plate is cut at a predetermined width from a direction intersecting each mating surface at an arbitrary angle, and a second metal plate is separated in which the cut of the second mating material forms a pattern derived from the predetermined pattern on the cut surface. Alternatively, in this method, instead of the second laminated material, square wires of multiple types of metal materials with different tones are used. Where a prismatic material is used in which a plurality of square wires are stacked on top of each other and joined together by diffusion welding so that at least one material end face of the end faces of the square wires forms a predetermined pattern. It has the following characteristics.

[Specific description of the invention]

Next, the present invention will be explained with reference to the accompanying drawings.

Figure 1 shows three types of metal plates A, B, and
A first laminated material 1 is shown in which C, are stacked on top of each other and joined together, and such a laminated material 1
The first metal plates 2 are cut along a plane perpendicular to each mating surface of the raw metal plates, and the first metal plates 2 are stacked so that the end faces of each material appearing on the cut surfaces form a predetermined pattern. Second laminate material 3 joined by
is shown in FIG. Then, when such a joining material 3 is cut again along a plane perpendicular to each mating surface of the first metal plate 2, the second metal plate thus separated is divided into the third metal plate. As shown in the figure, a metal composite plate 4 is obtained which has a striped pattern in which the rectangular cuts of the materials A, B, and C of the raw metal plates are arranged in parallel in an oblique direction.

Figure 4 shows a prismatic material 5 in which two types of square metal wires A and B with different tones are arranged alternately in the vertical and horizontal directions and joined together.
A lattice striped pattern is formed on the end face of the prismatic material 5 by two kinds of metal materials of different colors, and this is arranged in a plane perpendicular to each mating surface of the square wires. When cut along the length, a metal composite plate 6 having a checkered pattern composed of two different colors as shown in FIG. 5 is obtained.

In the above figures, the congruent square end faces of the respective materials of the second laminated material 3 and the prismatic material 5 are shifted vertically and horizontally by the length of one side to form a pattern. By changing the thickness of the second metal plate, the cross-sectional dimensions of the rectangular wire, and the selection and arrangement of these combinations, various unusual patterns can be created, such as the wavy pattern shown in FIG. Metal composite plates 7 and 8 having curved patterns as shown in the figure can also be produced, and the cutting directions of the first and second laminated materials, the shape of the cross section of the square wire, and the cutting direction of the square column materials can be varied. It is clear from the method of the present invention that the shape of the end face of each material can be changed to a rectangle or parallelogram other than a square if the shape is changed.

It is convenient to use a diffusion welder to join the metal plates and the square wires, and to use a wire saw, for example, to cut the laminated materials and the square columns.

In this invention, a metal plate or a square wire is used as the starting material, but if a square wire is used instead of a metal plate, it becomes somewhat troublesome to overlap them, and it is relatively difficult to form a pattern using fine end surfaces of the material. On the other hand, it has the advantage that both the joining process and the cutting process only need to be performed once.

〔Example〕

Next, the present invention will be specifically explained using examples.

Example 1 18K gold alloy with yellow color (Au: 75.15, Ag:
20.0, Cu: 4.85, numbers are weight%, the same applies below), white 18K gold alloy (Au: 75.15, Ag: 4.85, Pd:
20.0), and red 18K gold alloy (Au: 75.15,
Prepare a plate made of Ag: 5.0, Cu: 19.85) with a thickness of 1.05 mm each, and then
After cutting out 60 mm metal plates and degreasing 20 of each material metal plate, stack the white, yellow, and red sheets alternately in that order and charge them into a diffusion welding machine. Vacuum level: 2 × 10 ^-4 torr Raise the temperature while holding 800
After holding the scorching heat at 800°C for 1 hour, pressurization was started, and joining was performed by diffusion welding under the conditions of 4 hours of holding at a temperature of 800°C and a pressure of 4 ton/cm ² .

Next, the joined product (first joining material) as shown in Fig. 1 was taken out from the welding machine and cut with a wire saw (wire diameter: 0.16 mmφ, cutting with abrasive material) to form a first part with a thickness of 1.04 mm. 48 metal plates were separated, and 48 of them were stacked together, and then recombined using a method similar to the above-mentioned joining method to create a second laminated material as shown in Figure 2.

This second laminated material was cut with a wire saw similar to that described above, and second metal plates with thicknesses of 2 mm and 5 mm were separated.
A metal composite plate having a striped pattern formed by arranging regular square end faces of white A, yellow B, and red C within 1.05 mm in a diagonal direction in parallel was obtained.

Example 2 Materials are red-colored copper and white-colored stainless steel (SUS304), each side is 2 mm.
Prepare square wires, then cut 60 mm long square wires, degrease 250 square wires of each color tone, and then overlap them so that the copper wires and stainless steel wires are arranged vertically and horizontally alternately and diffusion weld them. Charge the machine and vacuum level:
The temperature was raised while maintaining 2×10 ^-4 torr, and after maintaining the scorching heat at 900°C for 1 hour, pressurization was started.
Temperature: 900℃ (constant), Pressure: 3 at 9ton/ ^cm2
Joining was performed by diffusion welding under time-holding conditions.

Next, the joined product (prismatic material) as shown in FIG. 4 taken out of the welding machine was cut with a wire saw in the same manner as in Example 1, and metal plates with a thickness of 3 mm were separated, as shown in FIG. 5. A metal composite plate was obtained which had a checkered pattern in which red A and white B square end faces were arranged alternately two-dimensionally, and each square had a side of 1.95 to 2.05 mm.

From the above results, it can be seen that the obtained metal composite plate has a varied, delicate, and uniform surface pattern.

[Overall effect]

As mentioned above, the method of the present invention is characterized by combining a unique pattern formation method with a diffusion welding method that can join many metal plates and square wires with almost no deformation. Since it is possible to produce a metal composite plate that is highly durable and has a precise and regular pattern, the method of the present invention is suitable for producing decorative metal plates used as materials for various accessories, ornaments, crafts, etc. It exhibits particularly excellent effects.
