Description

Technical Field

[0001] The utility model relates to the field of steel bars, and more specifically, to a device for removing rust from the surface of steel bars. Background Art

[0002] Rebar refers to steel used for reinforced concrete and prestressed reinforced concrete. The cross section of the steel bar is round, or sometimes square with rounded corners.

[0003] After searching, the existing patent (publication number: CN217726381 U) discloses a construction steel bar rust removal device, including a support frame, a moving component, a rust removal component and a clamping component. The support frame is a U-shaped structure, the moving component is symmetrically installed on the left and right sides of the upper end of the support frame, the rust removal component is installed between the two moving components, and the clamping component is symmetrically installed on the front and back sides of the upper end of the support frame. The clamping component is used to position and fix the steel bar. The present invention can solve the problems that the existing construction steel bars are usually unable to accurately remove rust from the steel bar surface during rust removal processing, the rust removal effect is poor, the rust removal is incomplete, and a large amount of rust impurities still remain on the steel bar surface. At the same time, when the existing construction steel bars are undergoing rust removal processing, a large amount of rust impurities are usually easily adhered to the cleaning brush bristles, and the impurities are usually not cleaned, so that the cleaned impurities are easily attached to the steel bar surface again. The inventor found that the existing technology has the following problems in the process of realizing the utility model:

[0004] Existing steel bars will corrode and rust when left for a long time. When they are used, the rust on the surface needs to be polished off before they can be used. The existing rust removal equipment sends the steel bars to the rust removal machine for polishing. The positioning conveyor during transportation usually conveys steel bars of fixed sizes. When conveying steel bars of different sizes, the conveying rollers need to be replaced, which is less convenient to use. Therefore, a conveying mechanism is required to facilitate the fixed conveyance of steel bars of different sizes. At the same time, the above-cited patent documents do not propose relevant solutions to solve the problem of positioning and conveying steel bars of different sizes.

[0005] Therefore, a kind of steel bar surface rust removal equipment is proposed in response to the above problems. Utility Model Content
