Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention can be used for all kinds of industrial brushes such as twisting brushes, coil brushes, wheel brushes, roll brushes, cup brushes, and particularly for polishing or grinding the surface of hard workpieces. The present invention relates to a brush material that can be used for deburring and the like.

[0002]

2. Description of the Related Art As is well known, many types of brush materials have been developed. For example, there are metal wires, natural or synthetic fibers, and synthetic fibers containing abrasive grains are known.

[0003]

The conventional brush material is selected and used according to factors such as the material and structure of the work, dimensions, polishing, grinding and deburring, and the like. There is a certain effect. However, when the work is metal and extremely hard, it is difficult to treat the work with a conventional brush material made of fiber. That is, if the work is a hard metal, the surface treatment such as polishing and grinding cannot be performed unless the brush bristles are harder than that, and even if the surface treatment can be performed, the processing time is extremely long. In addition, the life of the brush material is short and must be replaced frequently. Therefore,
The work efficiency of polishing and grinding is remarkably reduced, and is not practical at all. Accordingly, an object of the present invention is to provide a material for a brush that can reliably and extremely quickly polish, grind, and deburr any work made of any material.

[0004]

In order to achieve the above object, according to the first aspect of the present invention, a polishing powder is attached to a surface of a metal wire by plating. It is characterized by the following.

According to a second aspect of the present invention, in the first aspect of the present invention, after the surface of the metal wire is plated with a soft metal, a polishing powder is adhered by mechanical means. , Followed by plating.

According to a third aspect of the present invention, in the first or second aspect, the metal wire is made of iron, iron alloy, titanium, steel, copper, or the like, and has a circular cross section. , A polygonal configuration.

According to a fourth aspect of the present invention, in the first aspect of the present invention, the granular material is selected from silicon carbide, aluminum oxide, diamond, titanium, and stainless steel. One or two
It is a configuration that is more than one kind.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below based on an embodiment shown in the drawings. FIG. 1 is a perspective view of a part of a state where a metal wire is plated with a soft metal, FIG. 2 is a perspective view of a part of a state where a polishing powder is attached to a surface plated with a soft metal, and FIG. FIG. 3 is a perspective view in which a surface to which polishing powder is attached is plated.

In the present invention, the surface of the metal wire 1 used as the bristle for the brush is plated in advance with a soft metal. As the metal wire 1, iron, iron alloy, steel, phosphor bronze, brass, and other ordinary metal wires used as brush hairs can be used. Any shape such as a cylindrical shape can be used. Further, the metal wire 1 may be a single wire or a composite wire obtained by twisting a plurality of wires, and a wire having a thickness of about 100 microns to several millimeters can be used similarly to a normal brush hair. .

According to the present invention, the surface of the metal wire 1 is plated with a soft metal as a first step. The soft metal is aluminum, copper, silver, zinc, gold, or an alloy thereof. When plating is performed with one of the above soft metals, a soft metal thin film 2 is formed on the surface of the metal wire 1. You. Examples of the plating method include an electroplating method, a chemical plating method, a hot-dip plating method, and a vapor phase plating method, and the most practical method may be selected.

Since the thin film 2 made of a soft metal has relatively good adhesion, the polishing powder 3 is firmly adhered to the surface of the thin film 2 by mechanical means as a second step of the present invention. The polishing powder 3 is used for polishing, grinding or deburring a work, and it is most preferable to use a hard diamond powder, but titanium powder, stainless steel powder, aluminum oxide powder , Such as silicon carbide powder, if the composition is generally used as abrasive grains,
Any kind can be used.

As shown in FIG. 4, a plurality of grooved rolls 4 are opposed to each other so that the polishing powder 3 is mechanically attached to the thin film 2 on the surface of the metal wire 1. It is most common that the metal wire 1 is inserted and pressure-bonded. If the polishing powder 3 is temporarily fixed to the surface of the thin groove 2 in advance with an adhesive, the polishing powder 3 is surely fixed. It can be reliably fixed to the surface of the metal wire 1 via the thin film 2.
However, in the present invention, the mechanical fixing of the polishing powder 3 is not limited to the roll 4, but any conceivable means can be used.

The polishing powder 3 may be applied to the surface of the thin film 2 by covering the entire surface of the thin film 2.
What is necessary is just to cover about 50% or more in area ratio. This is because the function as the brush bristles with abrasive grains may be generated.

After the polishing powder 3 is firmly adhered to the surface of the metal wire 1, as a third step, the surface of the metal wire 1 is plated to form a surface coating 5. The plating in the third step may be performed not only with the soft metal in the first step but also with chromium, cobalt, nickel, tin, lead, or an alloy thereof.

The plating process in the third step is for stabilizing the polishing powder 3 adhering to the surface of the thin film 2, and therefore, it is preferable that the film thickness by plating is thick. Accordingly, of the plating methods in the first step, a hot-dip plating method capable of thick plating is desirable, but another plating method may be used.

As described above, when the surface film 5 is formed on the surface of the metal wire 1 by plating, the polishing powder 3 is extremely stably and firmly adhered. Therefore, when the metal wire 1 is bound or attached to a metal fitting and used as a twisting brush, a coil brush, a wheel brush, a roll brush, a cup brush, or the like, the interaction between the metal wire 1 and the polishing powder 3 is significantly improved. It becomes a brush for polishing, grinding or deburring.

Although the present invention has been described with reference to the embodiments shown in the drawings, the present invention is not limited to the above-described embodiments. But it can be implemented.

[0018]

In summary, the present invention is characterized in that a polishing powder is attached to the surface of a metal wire by plating. Therefore, the sharpness of the work is remarkably good and the work is hard, so that it can be effectively used as a surface treatment of a particularly hard work which cannot be surface-treated conventionally or as a finish. Since the processing efficiency is good, the work time can be adjusted by adjusting the pressing force on the work.

Then, after the surface of the metal wire is plated with a soft metal, the polishing powder is adhered by a mechanical means, and then the plating is performed, whereby the polishing powder is securely fixed and peeled off. It can be used effectively until it is almost worn, without dripping or detachment, and has high practical value.
