Sand blasting and rust removing production line for inner wall of copper pipe

Abstract

The invention discloses a sand blasting and rust removing production line for the inner wall of a copper pipe, comprising mounting plates. 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; a sand blasting and rust removing assembly is mounted between the conveying assemblies; and the conveying assemblies and the sand blasting and rust removing assembly are both connected with a driving assembly in an engaged mode. According to the sand blasting and rust removing production line for the inner wall of the copper pipe, a driving motor of the driving assembly can drive the conveying assemblies to drive the copper pipe to do a linear motion, meanwhile, a rust scraping knife on a rotating pipe of the sand blasting and rust removing assembly can be driven to rotate to scrape rust in the copper pipe, and secondary rust removing operation is carried out on the inner wall of the copper pipe through high-speed quicksand, so that more thorough rust removal can be conveniently carried out on the interior of the copper pipe; and two sets of worms and a set of rotating pipes are driven to move at the same time through one set of driving motors, the conveying and rust scraping effects on the copper pipe can be achieved, the number of motors is reduced, and the cost is reduced.

Description

technical field [0001] The invention relates to the technical field, in particular to a production line for blasting and derusting the inner wall of copper pipes. Background technique [0002] Generally, the inner wall of the copper pipe is derusted by sandblasting, which is the process of cleaning and roughening the surface of the substrate by the impact of high-speed sand flow. ) is sprayed at high speed to the surface of the workpiece to be treated, so that the appearance or shape of the surface of the workpiece changes. 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 workpiece The mechanical properties of the surface are improved. [0003] However, when using sand blasting to derust the inside of the copper pipe, it is impossible to completely remove the large and fixed rust inside the copper pipe. Sometimes in order to speed...

Problems solved by technology

[0003] However, when using sand blasting to derust the inside of the copper pipe, it is impossible to completely remove the large and fixed rust inside the copper pipe. Sometimes in order to speed up the production line, the transmission speed of the copper pipe is often increased. , so that the impact time of the quicksand on the inner wall of the copper pipe is greatly reduced, resulting in a more obvious decline in the rust removal effect inside the copper pipe. Therefore, we propose a sandblasting and rust removal production line for the inner wall of the copper pipe to solve this problem
