Steel surface pretreatment device

Abstract

The invention discloses a steel surface pretreatment device which comprises an automatic feeding device. The automatic feeding device transfers steel to surface polishing equipment, and the surface polishing equipment derusts the steel and then transfers the steel to a reagent smearing and straightening device. The reagent smearing and straightening device comprises a plurality of arc-shaped fixing flaps, and after the multiple arc-shaped fixing flaps are combined, the middle of an arc-shaped fixing flap combination is provided with a through groove used for transferring the steel. The outer surfaces of the arc-shaped fixing flaps are provided with pressure applying pieces, and the inner surfaces of the arc-shaped fixing flaps are provided with smearing layers. The outer sides of the pressure applying pieces are connected with telescopic supporting rods which are controlled by a pressure applying device. Reagent holes used for introducing reagents are formed in the arc-shaped fixing flaps, and reagent quantitative guide pipes are connected to the reagent holes. The reagent quantitative guide pipes penetrate through the telescopic supporting rods and then are connected with a kit. According to the steel surface pretreatment device provided by the invention, automatic transferring and convenient and rapid derusting can be achieved, and meanwhile, the functions of straightening and reagent even smearing can further be achieved on the steel with the arc-shaped surface.

Description

technical field [0001] The invention relates to the field of mechanical processing, in particular to steel processing, and in particular to a steel surface pretreatment device. Background technique [0002] In the prior art, rust removal of steel is generally carried out by soaking in a rust removal solution. Rust removal by soaking depends on the time of soaking, and the process takes a long time. However, the stubborn rust spots on the surface of the steel are attached to the surface of the steel. If there is no external force to remove the rust Peeling, it is easy to cause stubborn accumulation, the effect of rust removal is not ideal, and it does not have the function of straightening steel wires, steel bars and other cylindrical steel materials and evenly applying protective agents on the surface after rust removal, which greatly affects the production efficiency and service life of steel materials , Product performance. [0003] Therefore, it is necessary to provide a...
