Steel pipe inner wall sand blasting derusting production line

Abstract

The invention discloses a steel pipe inner wall sand blasting derusting production line which comprises two sets of mounting plates, the two sets of mounting plates are symmetrically arranged up and down, four sets of supporting rods are arranged at the bottom of the lower mounting plate, conveying assemblies are mounted in a mounting cavity defined by the two sets of mounting plates, and a sand blasting derusting assembly is mounted between the conveying assemblies. The conveying assembly and the sand blasting and rust removing assembly are both connected with the driving assembly in an engaged mode. According to the sand blasting derusting production line for the inner wall of the steel pipe, a driving motor of the driving assembly can drive the transmission assembly to drive the steel pipe to do linear motion, and meanwhile, a rust scraping knife on a rotating pipe of the sand blasting derusting assembly can be driven to rotate to scrape rust in the steel pipe; and secondary rust removal operation is carried out on the inner wall of the steel pipe through high-speed quicksand, more thorough rust removal can be conveniently carried out on the interior of the steel pipe, the two sets of worms and the set of rotating pipes are driven by one set of driving motor at the same time, the conveying and rust scraping effects on the steel pipe can be achieved, the number of motors is reduced, and the cost is reduced.

Description

technical field [0001] The invention relates to the field, in particular to a production line for sandblasting and derusting the inner wall of steel pipes. Background technique [0002] Generally, the inner wall of the steel pipe is derusted by sand blasting, which is the process of cleaning and roughening the surface of the substrate by the impact of high-speed sand flow. Spray onto the surface of the workpiece to be treated to change the appearance or shape of the surface of the workpiece. Due to the impact and cutting effect of the abrasive on the surface of the workpiece, the surface of the workpiece can obtain a certain degree of cleanliness and different roughness, so that the surface of the workpiece Mechanical properties are improved. [0003] However, when using sand blasting to derust the inside of the steel pipe, it is impossible to completely remove the large and fixed rust inside the steel pipe. The impact time on the inner wall of the steel pipe is greatly re...

Problems solved by technology

[0003] However, when using sand blasting to derust the inside of the steel pipe, it is impossible to completely remove the large and fixed rust inside the steel pipe. The impact time on the inner wall of the steel pipe is greatly reduced, resulting in a more obvious decline in the rust removal effect inside the steel pipe. Therefore, we propose a sandblasting and rust removal production line for the inner wall of the steel pipe to solve this problem
