Description

  The present invention relates to a processing brush used for performing various types of processing such as grinding, polishing, surface treatment, cleaning, and deburring of a surface to be processed.

  Conventionally, various processing brushes have been known, and as a grinding tool for peeling paint, the required number of grinding materials twisted on a rope with steel wire rods and a synthetic resin filament grinding material mixed with alumina are used. The required number of the converging pieces are alternately folded and sandwiched together with a core wire in a U-shaped metal fitting, and the metal fitting is wound in a spiral shape and welded and fixed to a disk metal fitting. There is known a technique in which a metal plate is sandwiched between U-shaped metal fittings and welded and fixed to a disk metal fitting so as to cover most of the grinding material formed in a spiral shape with a thin plate portion (Patent Document 1). In the paint peeling grinding tool described in Patent Document 1, the thin plate attached to the peripheral surface of the grinding material prevents the property of the material from turning up due to the rotation of the tool and the resistance of cutting. As a result, it was possible to maintain a proper grinding action.

  Also, in a rotating brush in which a brush part is formed by fixing a large number of steel wire strands to a flange, a binding band made of an elastic material is attached around the brush part, and the strand attitude when the flange is not rotated Is known that is bent in the flange central axis direction (Patent Document 2). The rotating brush described in Patent Document 2 has an effect of preventing the life of the brush part from being shortened due to a large deflection of the outer periphery of the brush part due to centrifugal force during high-speed rotation.

  Furthermore, an annular core having a U-shaped cross section and having a recessed portion on the outer periphery, a ring fitted to the recessed portion of the core, and both ends radially by hooking an intermediate portion on the ring In a cup brush composed of a plurality of protruding brush portions, a rubber layer having a predetermined thickness is formed by impregnating the outer peripheral layer portion of the brush portion with rubber, and the rubber layer including the brush portion What formed the wave-like part which a peak part and a trough part continue in the circumferential direction at the outer peripheral part alternately is known (patent document 3). In the cup brush described in Patent Document 3, the brush portion is maintained at approximately 45 ° with respect to the surface to be polished even during high-speed rotation, and the tip of the brush portion comes into contact with the surface to be polished to obtain a high polishing force. As a result, the wire breakage is small, the polishing range is wide, and the work efficiency can be improved.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In addition, this invention is not limited by this embodiment.

  FIG. 1 is a front view showing a first embodiment of a processing brush according to the present invention, and FIG. 2 is a cross-sectional view of the processing brush of the first embodiment. As shown in FIGS. 1 and 2, a processing brush 10 for performing various processes such as grinding, polishing, surface treatment, cleaning, and deburring of a work surface includes a base 1, a channel brush 2, and a channel brush. And fixing means (not shown) for fixing 2 to the base 1. As the fixing means, various methods such as welding and adhesion can be employed at appropriate times.

  The channel brush 2 includes a brush piece 4, a core wire 5, and a strip 3. Note that the channel brush 2 may be configured by the brush piece 4 and the belt-like body 3 without including the core wire 5, and this is also included in the channel brush constituting the present invention. The strip 3 is usually made of a metal that is easy to process.

  The pedestal 1 has a fixed base 1a having a fixed surface for fixing the channel brush 2 and a rotating shaft 1b extending in a direction perpendicular to the fixed surface.

  The brush piece 4 is formed by being sandwiched and folded between the core wire 5 and the strip 3 or the strip 3. Moreover, the height of the side plate 3b of the strip 3 located outside the fixed surface of the fixed base 1a is higher than the side plate 3a of the strip 3 positioned inside the fixed surface of the fixed base 1a. 3 is fixed to the fixed surface of the fixing base 1a by fixing means.

  Therefore, the brush piece 4 has a shape in which the brush piece 4a on the side plate 3b side of the belt-like body 3 is linearly downward, and the brush piece 4b on the side plate 3a side of the belt-like body 3 has a shape spreading toward the bottom. Thereby, by preventing the brush pieces 4 of the channel brush 2 from expanding, the density of the brush pieces 4a can be increased, so that the cutting ability with respect to the work surface can be increased. Further, since the number of parts is not newly increased and the strip 3 constituting the channel brush 2 can be easily processed, an increase in manufacturing cost can be prevented.

  FIG. 3 is a front view of a conventional processing brush, and FIG. 4 is a cross-sectional view of the conventional processing brush. When the conventional processing brush 20 shown in FIGS. 3 and 4 is compared with the above-described processing brush 10 according to the present invention, the belt-like body 3 constituting the processing brush 10 according to the present invention is the same as that of the fixed base 1a. The height of the side plate 3b of the strip 3 located outside the fixed surface is higher than the side plate 3a of the strip 3 positioned inside the fixed surface of the fixed base 1a. The band-like body 7 of the channel brush 6 constituting the brush 20 is different in that both side plates 7a and 7b are formed with substantially the same height.

  Thus, in the brush piece 4 of the processing brush 10 according to the present invention, the brush piece 4a on the side plate 3b side of the strip 3 is linearly downward, and the brush piece 4b on the side plate 3a side of the strip 3 is downward. On the other hand, in the conventional processing brush 20, the brush piece 8b on the side plate 7a side and the brush piece 8a on the side plate 7b side both have a shape spreading toward the bottom.

  Therefore, the same shape is used for the pedestal 1, the lengths of the brush piece 4 and the brush piece 8 are set to substantially the same dimensions, the bottom plate 3c of the strip 3 and the bottom plate 7c of the strip 7 are set to the same dimensions, When the side plate 3a of the strip 3 and the side plate 7a of the strip 7 have substantially the same dimensions, the maximum outer diameter L1 of the brush piece 4 of the processing brush 10 according to the present invention is the conventional processing brush 20. It becomes smaller than the maximum outer diameter L0 of the brush piece 8.

  FIG. 5 is a bottom view showing the first embodiment of the processing brush according to the present invention. As shown in FIG. 5, the processing brush 10 is formed such that the brush piece 4 of the channel brush 2 fixed to the fixed base 1 a of the base 1 has a substantially ring shape. Therefore, the brush piece 4a on the side plate 3b side with a high height forms the outer periphery of the substantially ring-shaped brush piece, and the brush piece 4b on the side plate 3a side with a low height forms the inner periphery of the substantially ring-shaped brush piece. Therefore, when used as a rotating brush that rotates around the rotating shaft 1b, it is possible to prevent core blurring and to rotate the brush at high speed. In particular, when the channel brush is manufactured in a substantially ring shape, the height of the side surface of the band-like body of the channel brush is formed higher than the height of the other side surface, so that the brush piece 4 is inclined toward the outer peripheral side. Can prevent spreading.

  FIG. 6 is a bottom view showing a second embodiment of the processing brush according to the present invention. As shown in FIG. 6, the processing brush 30 is formed so that the brush piece 9 of the channel brush fixed to the fixed base 1a of the base 1 has a substantially polygonal shape (substantially triangular shape in FIG. 6). . Therefore, the side plate-side brush piece 9a having a high height forms the outer periphery of the substantially polygonal brush piece, and the side plate-side brush piece 9b having the low height forms the inner periphery of the substantially polygonal brush piece. Therefore, when used as a rotating brush that rotates around the rotating shaft 1b, it is possible to prevent core blurring and to rotate the brush at high speed. Moreover, the cutting ability with respect to a to-be-processed surface can be improved with the corner | angular part 9c of the substantially polygonal brush piece 9, 9c.

  In addition, the channel brush can employ, for example, a spiral shape in addition to the above-described substantially ring shape or substantially polygonal shape. Moreover, although not shown in figure, the structure arrange | positioned so that the side surface with the high height of the side surface of the strip | belt-shaped body of a channel brush may become a back side with respect to the rotation direction of a base is also employable. Various shapes and materials can be used for the brush pieces according to the purpose.For example, when a brush piece having an approximate waveform shape in the longitudinal direction of the brush piece is used, the brush piece on the side plate side having a low height is used. Since it can be further expanded to the inside, the cutting ability with respect to the work surface can be further increased.

  The processing brush of the present invention is used for performing various types of processing such as grinding, polishing, surface treatment, cleaning, deburring and the like of a work surface.
