Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of forming a metal material as a workpiece and applying a surface makeup of a color other than a normal ground color to the workpiece. In particular, a color can be formed utilizing the texture of the material. It relates to a novel surface makeup method.

[0002]

BACKGROUND OF THE INVENTION Methods of applying surface makeup to a metal material include, for example, painting the surface of the material with a paint, plating the surface of the material with a thin layer of gold, silver, chrome, nickel, etc., and metal such as aluminum in a vacuum. There are various methods such as evaporation, which heats and evaporates and adheres it to the surface of the material as a thin film, and polishing and grinding with a wire brush or grinder. Of these methods, painting and plating are often performed as a method that allows the workpiece to relatively freely develop a color other than the normal temperature ground color. However, paint and plating may discolor or fall off over time, and when the metal material to be processed is a decorative product, a color development that makes use of the texture of the metal itself is required. There are limits to techniques such as plating and plating.

[0003] Various attempts have been made from the above,
For example, a technique has been developed in which a fine mark is imprinted on the surface of a metal material, and a rainbow surface is decoratively processed on the material surface by utilizing a light diffraction phenomenon. However, such a method does not color the metal material itself, but it is possible to process the rainbow surface because it utilizes the diffraction phenomenon of light, but it is possible to specify the location of the workpiece arbitrarily and create a different color. It was difficult to apply. In addition, there is also a problem that the cost is high and the processing steps are complicated, so that it has not yet been put to practical use, and there has been a demand for the development of a surface cosmetic method capable of developing a color utilizing the texture of the metal material itself.

[0004]

[Technical Problems Attempted to Be Developed] The present invention has been made in view of such a background, and the texture of a metal material itself is polished by polishing the surface while the temperature of a workpiece is different from normal temperature. This is an attempt to develop a new surface cosmetic method for coloring using the color.

[0005]

According to the present invention, it is possible to form a color utilizing the material of the metal workpiece, and to maintain the color semipermanently. Further, since the color is formed while polishing the workpiece, the processing time is relatively short, and the cost can be reduced.

According to a second aspect of the present invention, in addition to the requirement of the first aspect, in addition to the requirement of the first aspect, the color development is performed by polishing at different temperatures to partially form a plurality of parts on one workpiece. It is characterized by coloring. ADVANTAGE OF THE INVENTION According to this invention, the new coloring method of a metal material is attained, and an added value and differentiation of a workpiece can be achieved.

[0007] Furthermore, a metal surface makeup method according to claim 3 is characterized in that, in addition to the requirements described in claim 1 or 2, the surface polishing of the workpiece is performed by a wire brush or a buff. Things. ADVANTAGE OF THE INVENTION According to this invention, the specific structure which implement | achieves color development making full use of the raw material of a to-be-processed object is attained, and a processing process is comparatively simple and cost reduction can be achieved.

According to a fourth aspect of the present invention, in addition to the requirements of the first, second, or third aspect, a different color is formed by changing the material of the wire brush in the polishing with the wire brush. It is characterized by the following. According to the present invention, it is possible to perform different colors depending on the material of the wire brush as well as the temperature of the workpiece.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the illustrated embodiments. In the description, the workpiece A processed by applying the present invention will be described, and then the metal surface decoration method of the present invention will be described substantially while describing the processing process of the workpiece A. First, workpiece A is shown in FIG.
A decoration representing the sunrise on the metal plate as an example, as shown in a sun A _1, and mountains A _2, the sea A _3, air A ₄
Is drawn. To describe the overall color scheme, sun A ₁ is exhibited a deep yellow mountain A ₂ is exhibited blue. The sea A ₃ shines receives sunlight A ₁ of which exhibits a generally blue portion exhibits a deep yellow.
The air A ₄ distant corners from the sun A ₁ of which exhibits a generally pale yellow receives sunlight A ₁ is exhibits a blue color. Incidentally sea A ₃ is one step higher than the other portion for applying a wave of representation, it is attached irregularities.

Next, the metal surface decoration method of the present invention will be described substantially while describing the processing steps of the workpiece A. (1) prefabricated first workpiece A is a metal plate made of iron or the like is used as an example as shown in FIG. 1, part of the sea A ₃ is to represent the waves, it is formed one step higher than the other portions You. Then sea A ₃
As an example, only the portion is dissolved in oxygen to form irregularities and express a wave. Then, to clarify the boundaries of the sea A _3, after grinding the boundary grinder or the like, subjected to a lower polishing a portion other than the sea A _3, and terminates the preliminary machining. Note that such preliminary processing, particularly the formation of the uneven surface, is appropriately performed as needed, and may be omitted. Further, in this embodiment, a metal plate formed in a flat plate shape is applied as the workpiece A, but a metal member having a curved surface such as a rod shape or a spherical shape can also be applied. Further, as shown in FIG. Can be applied.

(2) Finishing of Surface Finishing When the above-mentioned preliminary finishing is completed, surface finishing of coloring by polishing is applied. At that time, the workpiece A is first heated to a high temperature as shown in FIG. 1 and, as an example, exhibits a blue color as a whole. During the blue end of machining, since the basic colors, such as mountain A ₂ or sea A _3, the portion leaving the blue are masked as required. The workpiece A is polished with a brass wire brush B as a central portion or the air A ₄ is an example of a solar A ₁ and the sea A ₃ during high temperature state, and that these portions are colored dark yellow .
Then, the temperature of the workpiece A is slightly lowered and the sun A
₁ and mountains A ₂ etc., are masked as needed unnecessary portion in the color. Then, the sky A ₄ shining in response to the light of the sun A ₁ is polished again by the wire brush B made of brass, and this portion develops a pale yellow color.

As described above, the workpiece A is polished by the wire brush B at different temperatures, and develops a dark yellow, pale yellow, or the like at any place.
The color scheme described above is performed. In this embodiment, the surface is polished by a brass wire brush B as a surface makeup, but a copper or iron wire brush B can be applied, or a buff can be polished. is there. Also, the material of the wire brush B is not limited to one kind. For example, when the work A is made of brass when the temperature of the work A is high, and when the work A is made of iron, the work is performed when the temperature of the work A is slightly low. A form in which the material of the wire brush B is made different in color with the temperature of the workpiece A to form a color is also possible. Furthermore, in this embodiment, the workpiece A in which the metal surface makeup method of the present invention is applied to decorative articles such as works of art is illustrated, but the present invention is applied to various metal products such as chairs, desks, and bookshelves. It is possible.
