Abstract

PURPOSE: To provide a cup brush capable of covering the brush part with a foil guard, even when mounted on a power tool, and doing safe grinding work without facing chippings or broken wire strips arising in grinding, if scattered by centrifugal force, to the front side because of the foil guard. CONSTITUTION: A cup brush has a sectionally U-shaped annular core 11 provided with a recess 12 in the outer periphery, a ring fitted to the recess 12 of the core 11 and the brush part formed with a number of wires 14 having both ends radially protruded by catching the middle on the ring 13. The upper layer of the brush part 15 is impregnated with rubber to form a rubber layer 15 with a preset thickness of urethane rubber.

2. Description of the Related Art As a tool for polishing and finishing a machined surface of a metal or a welded portion, and polishing and removing burrs and rust generated on a metal surface, excellent polishing ability and a good finished surface can be obtained. Many cup brushes are used. This cup brush has an annular metal core having a U-shaped cross section and a concave portion on the outer periphery, a metal ring fitted in the concave portion of the core, and an intermediate portion in the ring. It is composed of a brush portion composed of a large number of wires whose both ends are radially projected by being hooked.

This cup brush is a flat bevel type, and a crimping plate is provided in the central portion, and a mounting portion such as a screw hole is provided in the central portion of the crimping plate. Then, this cup brush is attached to a commercially available electric tool, rotated, and the lower surface of the brush portion is pressed against the surface to be polished, whereby burr and rust on the mirror surface of the surface to be polished can be polished and removed.

By the way, a commercially available power tool is shown in FIG.
As shown in FIG. 3, a flat disc-shaped grindstone 3 is attached to the rotary shaft portion 2 of the electric tool main body 1 so that it can be used as a grinder for grinding a surface to be ground. The electric tool main body 1 is provided with a wheel guard 4 that covers a part of the grindstone 3 so that chips generated during grinding and grindstone particles generated due to abrasion do not scatter to the hand side.

This is because the commercially available electric tool is designed so that it can be used as a grinder by mounting the grindstone 3, and although the mounting of the cup brush 5 is not considered, the cup brush 5 is not considered. It is possible to wear. Therefore, when the cup brush is attached to a commercially available electric tool, the entire brush portion 6 of the cup brush 5 is exposed, and the brush portion 6 spreads in the outer peripheral direction due to centrifugal force and pressing force during rotation. . When the brush portion 6 spreads too much in this way, the tip of the wire becomes horizontal or upward and separates from the surface to be polished, and the middle of the wire comes into contact with the surface to be polished, resulting in a disadvantage that polishing efficiency decreases.

At this time, the wire forming the brush portion 6 hits the core or the edge portion of the crimping plate,
Since a force is applied in the direction of bending the wire, there is a risk that the wire will be broken during polishing and the broken wire piece will be scattered by centrifugal force.
