Description

Technical Field

[0001] The utility model relates to the technical field of PC steel bar rust removal equipment, in particular to a steel bar rust removal equipment for PC steel bar production. Background Art

[0002] Steel rod is a hollow, long, round steel bar, which is widely used in industrial pipelines and mechanical structural components in the fields of petroleum, chemical industry, medical treatment, food, light industry, mechanical instrumentation, etc. In addition, it is lighter in weight when the bending and torsional strength are the same, so it is also widely used in the manufacture of mechanical parts and engineering structures. Before painting, the surface of the steel rod needs to be derusted.

[0003] Publication (Announcement) No. CN218613352U discloses a rust removal device for steel bar processing, specifically relating to the technical field of steel bar processing equipment. The device comprises a first side plate, a second side plate, a screw, a drive motor, a connecting rod, a rust removal element, a fixing rod, a limiting mechanism, and steel bars. This device can remove rust from two steel bars simultaneously, replacing manual rust removal and improving work efficiency. The first elastic telescopic rod applies pressure to the rust removal piece, resulting in effective rust removal.

[0004] Although the above scheme has the advantage of improving work efficiency, in actual use, the surface of the steel rod is only clamped by the elastic telescopic block and the limit block in the limit mechanism, and the fixing effect of the steel rod is poor. The steel rod is prone to shaking during the rust removal process, and the rust on the surface of the steel rod is only removed by the vertical movement of the rust removal part, and the rust removal effect is poor. For this reason, we propose a steel rod rust removal equipment for PC steel rod production. Utility Model Content
