Abstract

The invention discloses method and equipment for cleaning an oxide skin on the outer surface of a copper pipe, wherein the method comprises the step of: continuously passing through a pipe blank of the copper pipe through a rough brushing device, a medium brushing device and a fine brushing device which are arranged coaxially for respectively sequentially carrying out primary brushing, medium brushing and fine brushing on the outer surface of the pipe blank of the copper pipe to realize primary brushing, medium brushing and fine brushing on the surface of the pipe blank, and removing the oxide skin. The equipment mainly comprises a stand, and the rough brushing device, the medium brushing device and the fine brushing device which are arranged on the stand at intervals. Copper powder wastegenerated in the method is greatly reduced, and the predicted yield can reach 99.5 percent; and the equipment is convenient for use and has good cleaning effect on the oxide skin on the surface of the pipe blank.

Description

technical field [0001] The invention relates to the technical field of copper casting blank processing, in particular to a cleaning method and cleaning equipment for treating impurities such as dirt and oxide layers on the surface of copper casting tube blanks. Background technique [0002] Copper coils use horizontal continuous tube blanks for planetary rolling to remove defects such as scale on the surface to ensure that these defects will not cause scraps such as breakage and sawtooth damage during subsequent stretching. The traditional process removes surface defects by milling the surface of the tube blank with a milling cutter and wet processing with cutting fluid. The single-sided milling amount is generally 0.3-0.5mm, and the yield is low, about 97%. The milling chips still need to be dried, and there are oil stains everywhere. After these oil stains evaporate, they will endanger human health, not only consume high energy, but also pollute the environment. [0003] ...
