Description

  The present invention relates to a method for forming a rough surface of a molded body that roughens the surface of a solid molded body, and a tool for forming a rough surface of a molded body used for roughening the surface of a solid molded body. About.

As a method for roughening the surface of a solid molded body made of glass, resin, or metal to form a matte surface or a satin surface, hard solid particles such as metal coarse particles, sand, and abrasives are molded. The sandblasting method, which sprays on the surface of the body, is well known.
However, this sandblasting method requires a device for spraying solid particles such as the metal coarse particles, sand, and abrasives onto the molded body, and a measure for preventing the solid particles such as metal coarse particles, sand, and abrasives from being scattered. . In the case of displaying a pattern such as a figure, a letter, or a symbol on the surface of a transparent molded body such as glass or resin, or on the glossy surface of a metallic molded body by a matte surface or a satin surface. As disclosed in Japanese Patent No. -52899, it is necessary to mount a pattern from which a figure, a character, or a symbol to be displayed is cut out on the surface of the molded body in advance. Therefore, this sandblasting method is suitable for mass production of solid molded bodies made of glass, resin, or metal in factories, but for example, repairing the satin finish of metallic molded bodies that have become glossy due to damage. Therefore, it is not suitable for forming a small rough surface.

Furthermore, considering the prevention of scattering of solid particles such as the above-mentioned metal coarse particles, sand, and abrasives, the sand blasting method is preferably carried out in a sealed container or a room provided with anti-scattering measures. There is a limit to the size of a molded body that can form a surface and a satin finish. Therefore, the rough surface of a large molded body is rubbed with an abrasive or corroded with an acid, or a method in which a material on which a rough surface has been formed in advance is processed into a molded body. Particularly, a stainless steel molded body having a satin finish on the surface, especially metal, is often made by processing a stainless plate (2B finish) on which a satin finish has been formed in advance. Japanese Patent No. 147900 discloses a surface shape adjustment method in which stainless steel is annealed in an oxidizing atmosphere and then subjected to an electrolytic pickling treatment to finish it to a whitish surface.
However, when processing a metal plate, especially a stainless steel plate (2B finish), on which a satin finish has been formed in advance to make a molded body, the surrounding satin finish is polished by polishing the portion after cutting or welding. Or part of the satin surface may become glossy due to the pressing force applied by the contact between tools or materials. Even if the mirror-finished or glossy surface has a small area, it must be treated as a defective product depending on the product. In particular, a large product has a large loss and cannot be ignored. Therefore, whether or not the mirrored or glossy part can be repaired depends on the product price, but conventional matte surface forming methods such as sandblasting and oxidation annealing have special equipment. Even if you ask a factory that has the equipment, you will be entrusted and transported, and you will not be able to expect the cost reduction effect. For this reason, until now there is no means to restore the glossy 2B finish to a matte surface, and when processing the 2B finish, the polished part after cutting or welding should be made as small as possible or 2B It was necessary to work with great care so as not to bring the tool into contact with the surface of the finishing material or between the materials.

In particular, in a vibration hammer, the surface thereof is set to a small area, the vibration hammer itself is moved on the surface of the molded body 1, and a rough surface is formed by abutting a small area of abrasive cloth paper at different locations on the surface of the molded body. It is possible to use such a method, and a rough surface having a fine shape can be formed on the surface of the molded body. If a vibration hammer that vibrates in small increments by an ultrasonic vibration element is used, the above function can be realized effectively and easily.

According to the rough surface forming process method of a molded body surface of the present invention, the rough surface formed on the surface of the molded body is a part of a selected region of the molded body surface, and the rough surface forming tool Since the abrasive cloth paper is formed by contacting a part of a selected area of the surface of the molded body and pressing the pressed cloth against the surface of the molded body, as shown in FIG. If the abrasive cloth paper to be brought into contact with a part of the selected region of the surface of the surface is cut out into an arbitrary shape such as a figure, a letter or a symbol, and placed on the rough surface forming tool on the surface of the molded body Patterns of arbitrary shapes such as figures, characters, symbols, etc. can be easily displayed on the surface of the body with a rough surface.
In FIG. 2, 31 is a surface of a press or a vibration hammer, 32 is a surface of a rotating body or a roller, 40 is an abrasive cloth cut into a pattern shape such as a figure, a letter, a symbol, etc. ) Shows an example in which the polishing cloth 40 cut into the shape of a pattern such as a figure, a letter, or a symbol is placed in contact with the surface 31 of the press machine or the vibration hammer.
FIG. 2B shows a state in which abrasive cloth paper 40 cut into a pattern shape such as a figure, a letter, or a symbol is wound around the surface 32 of a cylindrical rotating body or roller and is in contact with the roll. is there.
In FIG. 2, the polishing paper 40 disposed in contact with the surface 31 of the press machine or the vibration hammer or the surface 32 of the rotating body or roller is described as being cut into a pattern shape such as a figure, a character, or a symbol. However, on the contrary, it may be abrasive cloth paper 40 from which patterns such as figures, characters, symbols, etc. are cut out. In this case, a transparent surface in which patterns such as figures, characters, symbols, etc. are embossed with a rough surface or It is displayed on the surface of the molded body as a glossy surface.

In the third embodiment of the present invention, as shown in FIG. 2, a rough surface forming process formed on a part of a selected region of the surface of the molded body is applied with a predetermined mask material on the surface of the molded body. This is the case.
In FIG. 3, 1 is a molded body, 2 is a tool for forming a rough surface on the surface of the molded body, 3 is a pressing tool, 4 is a polishing cloth, 8 is a rough surface in the shape of a character, and 50 is a mask material from which characters are cut out. , F is a pressing force.
In this embodiment, as shown in FIG. 3A, a mask material 50 with characters cut out is applied to the surface of the molded body 20, and a rough surface forming tool for the surface of the molded body is formed from the surface of the mask material 50. (A roller in FIG. 3) A pressing force is applied by a roller 2, and the polishing material surface of the polishing cloth 4 disposed in contact with the surface of the pressing tool 3 of the rough surface forming tool 2 on the surface of the molded body from the surface is used as a mask material. A rough surface corresponding to the concavo-convex surface of a large number of abrasive particles on the abrasive surface of the abrasive cloth paper 4 is brought into contact with the surface of the molded body 1 at the portion of 50 cut-out characters, as shown in FIG. As shown, characters are displayed on the surface of the molded body 1.
Although the mask material 50 in which characters are cut out is described in FIG. 3, the pattern cut out in the mask material 50 is not limited to characters, and an arbitrary shape, for example, a figure or symbol, or a figure, character, or symbol is synthesized. In addition, a pattern such as a figure, a character, or a symbol made with the mask material 50 is applied to the surface of the molded body 1, and a pressing force is applied by a rough surface forming tool on the surface of the molded body from above.
