Processing method for outer surface of TA1 cathode roller

Abstract

The invention relates to a processing method for the outer surface of a TA1 cathode roller. The processing method comprises four working procedures of turning, grinding, ultrasonic rolling and polishing. The single-sided thickness of the outer surface of the cathode roller is more than or equal to 5 mm through turning processing, so that the outer surface of the cathode roller has no oxide black skin, spinning lines, peeling and crack surface defects left by spinning processing; during grinding, a grinding wheel bar of a flap wheel continuously grinds and knocks the outer surface of the cathode roller to improve the roughness of the outer surface of the cathode roller, eliminate part of the processing residual stress and reduce the stress corrosion generated during raw foil electrolyzing of the cathode roller; the plastic flow structure is formed on the outer surface of the cathode roller by ultrasonic rolling, so that the stress corrosion is reduced during raw foil electrolyzing of the cathode roller; and the roughness of the outer surface of the cathode roller is further improved through polishing, so that the outer surface of the cathode roller is fine and smooth, has no color difference, has no black spots, straight grain and cross grain and has no mottles and pinhole surface defects. It is proved by the test that the copper foil produced by the method meets the requirements of high-end lithium battery copper foil, and the manufacturing period of the cathode roller is greatly shortened.

Description

technical field [0001] The invention relates to the field of electrolytic copper foil equipment manufacturing, in particular to a method for processing the outer surface of a TA1 cathode roll with a diameter greater than 2000mm Background technique [0002] With the rapid development of the electronics industry and new energy electric vehicles, the demand for copper foil is increasing, especially the demand for high-end lithium battery copper foil is increasing year by year. At present, the production of copper foil at home and abroad generally adopts the electrolysis method. The cathode roller is the core equipment for the production of copper foil by the electrolysis method. The cathode roll is used as the cathode for electrolytic copper foil, attracting copper ions to deposit on its surface to a certain thickness, after stripping, surface treatment, and winding, the electrolytic copper foil is continuously produced. What is the shape of the outer surface of the cathode r...
