Automatic production line and production method for anti-corrosion steel tubes

Abstract

The invention discloses an automatic production line and a production method for anti-corrosion steel tubes. The production method for anti-corrosion steel tubes includes the steps that steel tubes are turned into the front section of a derusting conveying line, and tube-tracking conveying is carried out towards the middle section of the derusting conveying line; the steel tubes are subjected to derusting in the middle section of the derusting conveying line; when the steel tubes obtained after derusting are conveyed to the rear section of the derusting conveying line, tube-separating conveying is carried out; the steel tubes are turned into the front section of a winding conveying line, tube-tracking conveying is carried out towards the middle section of the winding conveying line, and connection is carried out through tube connectors; the steel tubes are subjected to strip winding in the middle section of the winding conveying line; the steel tubes obtained after strip winding are conveyed to the rear section of the winding conveying line for tube-separating conveying. By using the speed-adjustable automatic conveying lines in coordination and cooperation with automatic derusting treatment equipment and automatic strip winding treatment equipment, the purpose of automatic flow production is achieved, the labor intensity is relieved, and the product quality and production efficiency are improved.

Description

technical field [0001] The invention relates to the technical field of anticorrosion production of steel pipes, in particular to an automatic production line and production method of anticorrosion steel pipes. Background technique [0002] The process of making the anti-corrosion steel pipe includes: first derusting, painting and drying the surface of the steel pipe; then beveling the two ends of the steel pipe; finally wrapping the outer surface of the steel pipe with a cold tape. [0003] At present, the process of implementing anti-corrosion steel pipes is basically carried out manually. The specific implementation steps are: spread the steel pipe evenly on the ground, and use manual hand-held air sandblasting to perform sandblasting and rust removal on the surface of the steel pipe; after the rust removal is completed, use a roller brush to roll paint on the surface; ; Finally, the steel pipe is wrapped with a cold wrapping tape by manual traction. The above artificial...

AI Technical Summary

Problems solved by technology

The above artificial anti-corrosion steel pipes have the following disadvantages: 1. When artificial air sandblasting can only be used to sandblast and derust the exposed part of the flat steel pipe, the uniformity of derusting can only be guaranteed by manually turning the steel pipe, which is difficult to do. The rust is evenly removed, and the requirements for paint adhesion and winding tape adhesion cannot be met, and the sand particles in the air sandblasting process are flying around in the air with the high-pressure air, making the working environment very poor; The method is: clamp both ends of the steel pipe and rotate the steel pipe, manually hold the winding belt, and wind it while walking from one end of the steel pipe to the other end. The uniformity of the winding depends on the speed of the manual walking. The thickness of the wound steel pipe is uneven, and It often happens that the workers do not break the belt in time at the end of the winding and cause the arm sprain accident; 3. When it is necessary to produce large quantities of anti-corrosion steel pipes, a large number of workers are required, the labor intensity is high, labor-intensive and time-consuming, and the quality of rust removal and winding quality Unstable and unable to meet the needs of modern production
