Description

Technical Field

[0001] The utility model relates to the technical field of rust removal wire brushes, in particular to a rust removal wire brush. Background Art

[0002] The wire wheel brush includes an outer bowl and an inner bowl with a central opening. The steel wire is wrapped inside to form an annular ring and embedded in the annular area between the outer bowl and the inner bowl, and extends out of the bowl mouth. The work of the wire wheel brush is to remove rust and other dirt from the surface of the workpiece through the friction between the high-speed rotating wire and the surface of the workpiece. Under this high-speed rotating working state, due to the action of centrifugal force, the removed rust and other dirt are scattered everywhere, which not only pollutes the environment, but some granular dirt and broken steel wire are rotated and flew out under the action of centrifugal force, causing harm to people.

[0003] For example, a wire wheel brush with application number CN201520602149.7 and authorization announcement date 20160210 includes a brush body and a plurality of steel wires fixed to the brush body. A mounting hole for facilitating installation of the wire wheel brush is provided at the center of the brush body's axis. The brush body has at least one groove formed on its surface. A pressure block for compressing the wires is fixed within the groove, with the wires secured between the groove and the pressure block. This utility model provides a wire wheel brush that, when the wires wear to a certain extent, requires only the pressure block to be removed and the wires replaced. This allows the brush body to be fully utilized, improving the utilization rate of the wire wheel brush.

[0004] When using a wire wheel brush for grinding and rust removal, the wire wheel brush is directly fixed to the output end of the angle grinder, and then the angle grinder is operated to rotate the wire wheel brush to grind the workpiece. However, this fixing method is relatively simple and cannot ensure the firmness between the wire wheel brush and the output end of the angle grinder. The problem of falling off is easy to occur during grinding and rust removal. Therefore, it is urgent to design a rust removal wire brush to solve the above problem. Utility Model Content
