Abstract

PROBLEM TO BE SOLVED: To provide a brush material and a brush which enable deburring and polishing/grinding to be quickly performed and are hard to be broken to fly around.SOLUTION: In a brush material, at least part of the surface of a metal wire material on which diamond abrasive grains are electrodeposited or welded is covered with a cover member.

Description

  The present invention relates to a brush material and a brush.

  Conventionally, various metal products have been deburred, polished and ground with various brushes. For example, when parts are processed in the automobile industry, aircraft industry, vehicle / ship industry, electronics / electric industry, etc., burrs are generated. If the burrs are removed and the parts are not used for assembly, the parts are Since a situation occurs in which the burrs cannot be placed in the position or the burrs are removed during the assembly and cause a failure such as a short circuit, the burrs are removed beforehand with a brush, and then the parts are used. Alternatively, the surface of a product or part may be polished and ground with a brush.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In the following drawings, components having substantially the same function are denoted by the same reference numerals for the sake of brevity.

(Embodiment 1)
The brush raw material of Embodiment 1 is shown to Fig.1 (a) (b). The first brush material 101 of this embodiment is obtained by applying a resin 30 to the surface of a metal wire 10 on which diamond abrasive grains 15 are electrodeposited, and the resin 30 contains abrasive grains 21.

  The second brush material 102 of this embodiment is obtained by applying a resin 30 to the surface of the metal wire 10 on which diamond abrasive grains 15 are electrodeposited. In the resin 30, two kinds of abrasive grains 21 and 22 are provided. Contained. That is, the second brush material 102 is different from the first brush material only in that there are two types of abrasive grains 21 and 22 in the resin 30.

  Examples of the metal wire 10 on which the diamond abrasive grains 15 are electrodeposited include a wire saw material. A wire saw is made of a material in which abrasive grains such as diamond are fixed to the outer peripheral surface of a core wire such as a piano wire by electrodeposition or the like, and is used for cutting a hard work such as metal or rock. When a wire saw is used to some extent, some of the abrasive grains are peeled off, the sharpness is lowered, and the cutting efficiency is lowered. Therefore, if the wire saw is used for a predetermined time, it is replaced with a new wire saw. However, since a considerable number of abrasive grains remain in the used wire saw, the polishing / grinding ability remains sufficiently. When such a used wire saw is used in the present embodiment, what is discarded is used as a material, so that the material cost can be kept low.

  Resin coating is performed by applying and drying a resin 30 mixed with one type of abrasive grain 21 or two types of abrasive grains 21 and 22 on the metal wire 10 electrodeposited with the diamond abrasive grains 15 as described above. The brush materials 101 and 102 according to this embodiment are completed. As the resin 30, various resins such as nylon, polyolefin, polyester, polyurethane, polyvinyl chloride, acrylic resin, and epoxy resin can be used.

  Examples of the abrasive grains 21 and 22 to be mixed with the resin 30 include alumina, zirconia, silicon carbide, cubic boron nitride, ceramics such as silicon oxide and cerium oxide, diamond, or metal such as SUS. Abrasive grains 21 and 22 in an amount of 2 wt% to 80 wt% are mixed with resin 30. In the case of brush bristles made of resin, only 30% by weight of abrasive grains can be mixed at the maximum in order to maintain the mechanical strength as brush bristles. However, more resin is used for the surface coating resin of the metal wire 10. Abrasive grains can be mixed, improving the polishing and grinding ability.

  Using such brush materials 101 and 102, the brushes 301 and 302 shown in FIG. 6 can be created. (A) is the single twist brush 301, and the single twist brush 301 is produced by sandwiching the brush material 101 between the two metal core wires 41 and twisting the metal core wire 41 as shown in (b). Further, the twisted core wire 41 is fixed, and a handle is attached to complete.

  (C) is a double single twist brush 302. As shown in (d), two types of brush materials 101 and 102 are sandwiched between four metal core wires 41 so as to be orthogonal to each other, and the metal core wire 41 is twisted. A double single twist brush 302 is produced.

  The brushes 301 and 302 of the present embodiment include the electrodeposited diamond abrasive grains 15 and the abrasive grains 21 and 22 mixed with the resin 30 as compared with a case where only a metal wire is used as a brush material. Therefore, since the polishing / grinding ability is remarkably high and the surface is coated with the resin 30, the brush material is hardly broken, and even if the brush material is broken during use, it is less likely to be scattered at high speed. The brushes 301 and 302 of the present embodiment having excellent polishing / grinding capability can be polished and ground sufficiently even when the pressing pressure against the object to be polished / ground is low. As a result, the scattering of the brush at a high speed is further reduced and the life of the brush is prolonged. Further, since the pressing amount can be reduced and the cover 30 is protected from being broken by the resin 30 as a cover member, the service life that can be used as a brush is significantly increased. If the brush material breaks and scatters at high speed, it may strike a nearby person and cause injury or injury, but if the brush material of this embodiment is used, there is almost no such danger.

  In addition, in the brush 302 shown in FIGS. 6 (c) and 6 (d), at least one type of brush selected from metallic brush hair, resin brush hair, animal brush hair, and vegetable brush hair as part of the brush material. It may be hair. By mixing the hair in this way, both the effect of the brush material of the present embodiment and the effect of the brush hair to mix the hair are exhibited.

  Further, at least a part of the surface of at least one kind of brush hair selected from metallic brush hair, resin brush hair, animal brush hair and vegetable brush hair is selected from resin, paper, cork, cloth and leather. It may be covered with one or more of the above-mentioned types, and this may be mixed with the brush material 101. In this case, the brush material may be 102 or a mixture of 101 and 102. Moreover, what covers the surface of at least one kind of brush hair body selected from metallic brush hair, resin brush hair, animal brush hair and vegetable brush hair may also consist of a plurality of types. Abrasive grains may be placed in the covering. The mixing amount of the abrasive grains is preferably 2% by weight or more and 80% by weight or less.
