Description

Technical Field

[0001] The present invention relates to the technical field of metal material surface treatment, and in particular to a high-strength steel surface treatment device for trailer production and a processing method thereof. Background Art

[0002] In trailer production, the surface treatment of high-strength steel pipes significantly impacts the product's corrosion resistance and structural strength. Traditional surface treatment processes typically employ a step-by-step cleaning and polishing process. For example, patent No. 201721837311.9 discloses a metal pipe polishing device comprising a crossbar support, on which left and right brackets are mounted, a polishing power assembly disposed above the two brackets, and a directional support rod disposed below the polishing power assembly, on which the polishing assembly is mounted.

[0003] However, when the above patent is used, it is impossible to clean the pipe before and after shot blasting. The problem of secondary adhesion of debris after shot blasting is prominent, and an additional cleaning process is required, resulting in reduced efficiency. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to propose a high-strength steel surface treatment device and a processing method for trailer production, so as to solve the problem that the existing high-strength steel surface treatment device cannot clean the pipe before and after shot blasting.

[0005] Based on the above-mentioned purpose, the present invention provides a high-strength steel surface treatment device for trailer production, comprising a conveyor platform, a shot blasting machine is provided in the middle of the conveyor platform, and cleaning parts are symmetrically provided on both sides of the shot blasting machine, characterized in that the cleaning part comprises a shell fixed on the conveyor platform, at least two groups of cleaning rollers are rotatably arranged in the shell, and a driving part for driving the cleaning rollers to rotate is also provided in the shell; the driving part comprises a ring corresponding to the cleaning rollers one by one and a transmission belt mounted on all the rings for transmission, the ring is rotatably arranged on one side of the inner cavity of the shell, a shaft is fixed on the ring, the cleaning roller is fixedly mounted on the shaft, the other end of the shaft is rotatably connected to the other side of the shell, and a servo motor for driving the ring to rotate is provided on the shell.
