Rust removing steel brush

Abstract

The invention discloses a rust removing steel brush, which comprises a framework, bristle and a cover plate. Installing holes are arranged on the surface of the framework; the bristle is arranged in the installing holes; edges of the framework press and fix the bristle through the cover plate; a steel brush action face formed by ends of the bristle has an inward arc in the direction vertical to the periphery, and a radius of the inward arc is of 30-40mm; the bristle has two shapes, one kind of the bristle is cotton-shaped steel wires subjected to bend shaping, and the other kind of the bristle is steel wire strands which are subjected to spirally tightening at root parts and decentralizing at top parts. The rust removing steel brush provided by the invention changes the material and the configuration mode of the surface bristle of the traditional steel brush and adopts 72B galvanized wires with a diameter of 0.4mm, so that over scratch on the surfaces of the wires is avoided and the service life of the bristle of the steel brush can be ensured as well; the two shapes of the bristle are adopted, so as to prevent the occurrence of the problems of wire-dropping, wire-breaking, wire-scattering, insufficient pressure and the like and greatly prolong the service life of the steel brush; and the radius of the arc on the surface of the steel brush is optimized to be 34mm, so that the rust on the surfaces of the wires can be removed furthest, and oxide skins on the surfaces of the wires can be completely removed.

Description

technical field [0001] The invention relates to a processing device in the field of metal drawing, in particular to a rust-removing wire brush used for surface polishing, grinding, rust removal and decontamination of metal products. Background technique [0002] Wire brushes used for rust removal on metal surfaces are almost all made of bristles made of equal-length steel wire ropes and fixed on the frame by pressing. The material of the bristles is very important. If the material is too hard, it is easy to cause scratches on the surface of the wire; if the material is too soft, the oxide skin on the surface of the wire is not easy to remove. The bristles of the wire brush are isolated from each other, which easily leads to problems such as wire stripping, broken wire, loose wire and insufficient pressure, and the service life of the wire brush is extremely short. [0003] The prior art has the steel wire rubber-covered brush wheel as described in the application number 200...

Problems solved by technology

The material of the bristles is very important. If the material is too hard, it is easy to cause scratches on the surface of the wire; if the material is too soft, the oxide skin on the surface of the wire is not easy to remove

The bristles of the wire brush are isolated from each other, which can easily lead to problems such as wire stripping, broken wire, loose wire and insufficient pressure, and the service life of the wire brush is extremely short

[0003] The prior art has the steel wire rubber-covered brush wheel as described in the application number 200920032242.3, which is characterized in that each steel wire is glued by polyurethane glue or resin glue or rubber. It can not effectively solve the problems of wire brushing, broken wire and loose wire on the surface of the wire brush, but increases the production process of the wire brush
