Description

Technical Field

[0001] The present application relates to a method for manufacturing multi-layer multi-color metal and its products, and in particular to a method for manufacturing multi-color three-dimensional metal parts and its products. Background Art

[0002] One of the common methods of forming patterns on the surface of metal products is to use mechanical reprocessing (such as chiseling and engraving) to form patterns. In addition, chemical etching is also a common method in the industry to form patterns on the metal surface. In recent years, the technology of using lasers (or lasers) to engrave on metal surfaces has become more mature and popular.

[0003] On the other hand, although patterns can be made on known metal products, most metal products or objects and the patterns on their surfaces can only present a single metallic color. In order to make the colors richer and more varied, it is necessary to spray paint, electroplating or chemical treatment (such as anodizing) to form different colors on the surface of the metal products.

[0004] In addition, the published Japanese Patent Publication No. 2003-52425 proposes a method of forming a pattern on the surface of a metal body by embedding a metal of a different material from that processed into the pattern shape into a recessed portion of a pattern shape formed by chiseling or the like, or by melting a metal of a different material and then pouring it into the recessed portion. This method forms a pattern with multiple colors on the surface of a metal body by using metals of different materials, colors and glosses.

[0005] In the published Chinese invention patent publication number CN102666125A, a metal body manufacturing method and an apparatus thereof, as well as a metal body manufactured by the metal body manufacturing method, are proposed. The method basically cuts the stacked multiple metal plates into multiple metal bodies after twisting, and then processes the multiple metal bodies through a joining process, a twisting process, a flat plate process and a twisting process to finally make a metal body with a pattern such as a ring or earring. Summary of the invention

[0006] The technical problem to be solved by the present application is to provide a method for manufacturing a multi-color three-dimensional metal part and its products, which can realize mass production and can complete three-dimensional metal parts with multiple colors without additional coloring process.

[0007] To achieve the above-mentioned purpose, a preferred embodiment of the method for manufacturing a multi-color three-dimensional metal part proposed in the present application includes the following steps:

[0008] The step of preparing a multi-layer multi-color metal composite plate comprises stacking three metal plates of red copper, brass and white copper to form a multi-layer multi-color metal composite plate;

[0009] The step of forming a three-dimensional shape is to use an automated forming device to form a three-dimensional metal piece with a three-dimensional shape from a multi-layer multi-color composite board; and

[0010] The step of forming a pattern is to use a mechanical cutting device to form multiple recessed portions with different depths on the surface of the three-dimensional metal part according to a default pattern. These recessed portions reveal the colors of the multi-layer multi-color metal composite plates at corresponding depths according to the preset depths to form a pattern with multiple colors, thereby completing the production of a multi-color three-dimensional metal part with a pattern.

[0011] In a preferred embodiment, in the step of preparing the multi-layer multi-color metal composite plate, three metal plates of red copper, brass and white copper are stacked to form a three-layer multi-layer multi-color metal composite plate.

[0012] In a preferred embodiment, in the step of preparing the multi-layer multi-color metal composite plate, three metal plates of red copper, brass and white copper are stacked to form a 15-layer multi-layer multi-color metal composite plate.

[0013] In a preferred embodiment, the thickness of the multi-layer multi-color metal composite plate is 1 mm.

[0014] A preferred embodiment of the method for manufacturing a multi-color three-dimensional metal piece of the present application includes: a splicing step of combining at least two multi-color three-dimensional metal pieces with patterns.

[0015] In a preferred embodiment, the splicing step utilizes a welding process to combine at least two multi-color three-dimensional metal pieces with patterns.

[0016] Another aspect of the present application also includes a multi-color three-dimensional metal part manufactured by the method for manufacturing the multi-color three-dimensional metal part.

[0017] The advantages and effectiveness of the present application are that by using a multi-layer multi-color metal composite plate, metal products with a variety of colors can be completed without additional coloring process. On the one hand, combined with automated forming devices and automatic engraving processes, three-dimensional metal parts with a variety of colors can be completed and mass production can be easily achieved.

[0018] In one embodiment of the method and its product of the present application, through careful modeling design and engraving, it can be made into metal parts such as plates and pots, and can also become a kind of craft painting that can present a colorful effect, which is very different from the traditional sculpture works that only use gold, silver, and copper metals to complete the monochrome display.

[0041] S3. The step of forming a pattern, using a mechanical cutting device to form a plurality of recessed portions with different depths on the surface of the three-dimensional metal part 30 according to a default pattern, wherein the recessed portions reveal the colors of the multi-layer multi-color metal composite plate at corresponding depths according to a preset depth to form a pattern with multiple colors, thereby completing the production of a multi-color three-dimensional metal part 30 with a pattern.

[0042] See also Figure 2 and Figure 3 A preferred embodiment of the step of preparing the multi-layer multi-color metal composite plate 10 is to stack three metal plates of different colors, namely, red copper C1, brass C2, and nickel silver C3, together, and then make the stacked red copper C1, brass C2, and nickel silver C3 into a multi-layer multi-color metal composite plate 10 by diffusion welding, cold rolling, and hot rolling; Figure 2 An exemplary cross-sectional structure shown is a multi-layer multi-color metal composite plate 10 having a three-layer structure formed by stacking three metal plates of red copper C1, brass C2, and white copper C3; Figure 3 An exemplary cross-sectional structure shown is a 15-layer multi-layer multi-color metal composite plate 10 made by sequentially and cyclically stacking three metal plates, namely, red copper C1, yellow brass C2, and white copper C3. In a preferred embodiment, the thickness of the multi-layer multi-color metal composite plate 10 is 1 mm.

[0043] A preferred implementation of the step of forming a three-dimensional shape utilizes an automated forming device, such as any one of a stamping device, a spinning device, and a stretching device, according to a predetermined pattern and the shape of the metal part 30 (such as a plate or a can), using any one of the processes including but not limited to stamping, spinning, and stretching to form the multi-layer multi-color metal composite plate 10 into a three-dimensional metal part 30 with a three-dimensional shape; of course, as other implementations of the method of the present application, a three-dimensional shape similar to a relief can also be formed on the multi-layer multi-color metal composite plate 10 by knocking.

[0044] See also Figure 4 The stress-strain curve of the multi-layer multi-color metal composite plate 10 used in the multi-color three-dimensional metal part 30 of the present application shows that the multi-layer multi-color metal composite plate 10 used in the multi-color three-dimensional metal part 30 of the present application has great deformation and tensile deformation capabilities, so before the pattern forming step, the multi-layer multi-color metal composite plate 10 can be subjected to large-scale deformation design to become a three-dimensional metal part 30.
