Surface rust removal treatment process for electrophoresis machining

Abstract

The invention relates to the technical field of surface rust removal treatment, in particular to a surface rust removal treatment process for electrophoresis machining. A rust removal device used in the process comprises a rectangular pool, a discharging barrel, an ultrasonic generator and a controller; one side wall of the rectangular pool is rotationally connected with a rotating rod; one end of the rotating rod is hinged to a rotating shaft; the discharging barrel is arranged on the rotating shaft in a sleeving manner; the rotating shaft is located at the center axis of the discharging barrel and fixedly connected with the inner wall of the discharging barrel through a supporting rod; and an opening is formed in the end, away from the rotating rod, of the discharging barrel. According to the rust removal device used in the surface rust removal treatment process for electrophoresis machining, a workpiece is driven by the discharging barrel to rotate in the rectangular pool, and then ultrasonic waves emitted by an ultrasonic wave emitter are used in cooperation, so that the workpiece in the discharging barrel is subjected to rust removal while shaking, the purpose of dead-corner-free rust removal of the workpiece is achieved, the cleanliness of the surface of the workpiece is improved, and the electrophoresis effect of the workpiece is promoted.

Description

technical field [0001] The invention relates to the technical field of surface derusting treatment, in particular to a surface derusting treatment process for electrophoresis processing. Background technique [0002] With the development of technological level, electrophoretic coating technology has gradually replaced traditional spraying technology and has been widely used in industrial production; to carry out electrophoretic coating, the surface of the product must be derusted; at this stage, for electrophoretic coating There are few special derusting devices. Manual derusting methods are used. The work intensity of workers is high, the working environment is harsh, and the efficiency of derusting is low. The use of acid solution for derusting is costly and improper treatment of acid solution will pollute the environment. ; Therefore, the current factory has achieved the purpose of rust removal through ultrasonic cleaning before electrophoresis. Ultrasonic rust removal is...

[0002] With the development of technological level, electrophoretic coating technology has gradually replaced traditional spraying technology and has been widely used in industrial production; to carry out electrophoretic coating, the surface of the product must be derusted; at this stage, for electrophoretic coating There are few special derusting devices. Manual derusting methods are used. The work intensity of workers is high, the working environment is harsh, and the efficiency of derusting is low. The use of acid solution for derusting is costly and improper treatment of acid solution will pollute the environment. ; Therefore, the current factory has achieved the purpose of rust removal through ultrasonic cleaning before electrophoresis. Ultrasonic rust removal is mainly done by using the synergistic effect of chemical agents and ultrasonic waves on the "cavitation" of the workpiece; the work The personnel first put all the workpieces into the ultrasonic cleaning tank and then clean them. However, due to the lack of existing technology, the rust on the contact part between the workpieces cannot be cleaned by ultrasonic waves, so that the rust removal on the surface of the workpiece after cleaning is not complete. The rust will hinder the electrophoretic paint, which will affect the electrophoretic effect of the workpiece
