Abstract

(57) [Summary] [PROBLEMS] To provide a whetstone provided with a decorative surface. SOLUTION: In a disk-shaped whetstone for grinding or cutting a metal material, a stone material, or the like, a decorative surface 3 is integrally formed and displayed on one whetstone surface.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a grindstone, and more particularly to a grindstone having a decorative surface.

[0002]

[Prior art]

 In building construction sites and pavement stone laying sites on sidewalks, etc., the surface of metal materials and stone materials is ground, deburred, and the entire shape is formed. A whetstone is used. In a conventional grinding stone, a powdered abrasive material and a liquid phenol resin are kneaded at a predetermined ratio to obtain a dried powdery (smooth, non-sticky state) property, and the powder is supplied in a predetermined amount. , Placed in a metal dish mold and pressed. If this is fired in a firing furnace at a temperature of 150 ° to 180 ° for about 24 hours, the phenolic resin melts and bonds the abrasives together, eventually hardening the whole, and a disk with a thickness of about 3 mm A grinding wheel is formed. Such a grindstone is attached to a grinder and rotated at high speed to grind or cut the surface of metal or stone.

[0003]

[Problems to be solved by the invention]

 The grinding wheel manufactured as described above disperses the heat generated by friction with the material to be ground (metal, stone, etc.), and its surface has various concave and convex shapes in order to increase the grinding efficiency or cutting efficiency. Also, on the surface (surface) opposite to the ground surface, a label stating a trademark, a manufacturer name, an abrasive, etc. is attached.

[0004] In the above-mentioned construction site, various machines and materials are placed, and vehicles and construction workers come and go. This is not a favorable environment for workers engaged in grinding and cutting due to a large amount of dirt and dust. Furthermore, grinding and cutting whetstones are consumables, so they are not designed and decorated, and workers are only engaged in grinding and cutting work and are environmentally very dry. The work efficiency was poor, and sometimes the hands and feet were injured by the rotating grindstone.

[0005] In view of the conventional grinding and cutting whetstones described above, the present invention displays a decorative decorative surface integrally on the whetstone, so that an operator can work in a pleasant atmosphere and environment. It is an object of the present invention to provide a grindstone capable of improving work efficiency.

[0006]

[Means for Solving the Problems]

 In order to achieve the above object, in the present invention, a decorative surface 3 for a person, an animal, a scenery, or the like is integrally formed on one surface of a disk-shaped grinding wheel for grinding or cutting a metal material or a stone material. In addition, the present invention puts decorative materials such as photographs and printed materials of humans, animals, landscapes, etc. on the upper surface of the mixed powder of the abrasive material and the phenolic resin placed in the mold, presses it, fires it, and puts it on one surface of the grindstone. The decorative surface 3 for animals, landscapes, etc. is integrally molded.

[0007]

[Embodiment of the invention]

 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 shows a grindstone main body 1 according to the present invention, and the material, manufacturing process, and the like of a disc-shaped grindstone 1 itself constituting the grindstone main body 1 are exactly the same as those of a conventional grindstone. The grindstone main body 1 of the present invention is characterized in that the decorative surface 3 is applied to the flat surface of the grindstone 1 at least on the surface opposite to the ground surface, and the grindstone 2 and the decorative surface 3 are integrally formed. . As the decorative surface 3, a known material such as a photograph or printed matter representing a person, an animal, a landscape, etc. together with colors can be used as a decorative material.

Next, a step of integrally forming the grindstone 2 and the decorative surface 3 will be described. Grinding an abrasive and a phenolic resin to form a powder and putting the powdered material into a mold is the same as a conventional grindstone. In the present invention, a paper decoration material such as a photograph or printed matter is placed on the upper surface of the powdered material placed in the mold (the surface opposite to the grinding surface when formed into a grindstone), and the whole is pressed. When this is fired in a firing furnace for a predetermined time (about 24 hours) and at a predetermined temperature (150 ° to 180 °), the resin melts, and this combines the abrasive and the decorative material, and the resin soaks into the decorative material. As a result, the abrasive and decorative material are integrated.

Both the abrasive and the decorative material after firing are hardened. When the whetstone was manufactured using the photographs in the above manufacturing process, the decoration material did not burn by firing because the resin was soaked, and the decoration material was melted into the surface of the abrasive material, There was no step as the thickness of the decorative material between the material and the decorative material, and the decorative surface 3 was directly drawn on the surface of the grindstone 2. Note that reference numeral 4 in the drawing denotes a connection hole to the grounder.

[0010]

[Effect of the invention]

 According to the present invention described above, the decorative surface 3 can be integrally formed and displayed on the surface of the grindstone 2 by placing the decorative material on the surface of the grindstone, pressing and firing, so that the grindstone main body 1 is designed. It will have an aesthetic appearance, attract attention on the construction site, and bring moisture to the construction site. The decorative surface 3 is integrated with the grindstone 2 and does not peel off.

In particular, since the decorative surface 3 can display various depictions of people, animals, landscapes, and the like along with colors, the grinding or cutting work can be performed by manufacturing the grindstone 2 having the various decorative surfaces 3. The user can select and use the grindstone 2 having the desired decorative surface 3, and can perform the grinding work with a pleasant feeling, thereby improving the work efficiency and reducing injuries caused by carelessness. Can be done.
