A surface derusting treatment process for electrophoresis processing

Abstract

The invention relates to the technical field of surface derusting treatment, in particular to a surface derusting treatment process for electrophoresis processing. The derusting device used in the process includes a rectangular pool, a discharge cylinder, an ultrasonic generator and a controller; One of the side walls of the rectangular pool is rotatably connected to the rotating rod; one end of the rotating rod is hinged to the rotating shaft; the discharging cylinder is sleeved on the rotating shaft; The inner wall of the discharge cylinder is fixed; the end of the discharge cylinder away from the rotating rod is provided with an opening; the derusting device used in the surface rust removal process for electrophoresis processing according to the present invention drives the workpiece through the discharge cylinder. Rotate in the rectangular pool, and then cooperate with the ultrasonic waves emitted by the ultrasonic transmitter, so that the workpiece in the discharge barrel can be derusted while shaking, so as to achieve the purpose of derusting the workpiece without dead ends, so that the cleanliness of the workpiece surface is improved. Promotes the effect of workpiece electrophoresis.

[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

[0003] For example, a Chinese patent with application number CN201820658147.3 discloses a rust removal device for surface treatment in electrophoresis production, including a base and a box. The bottom of the base is provided with universal wheels, and the center of one side of the base is The position is provided with a groove, and the first motor and the second motor respectively drive the first wire brush wheel and the second wire brush wheel to rotate in opposite directions, so that in the process of derusting, the workpiece to be derusted can be descaled. While rusting, it can also rotate automatically to make the rust removal process more thorough. At the same time, it can reduce the wear of the workpiece, reduce the loss rate, and improve the efficiency of rust removal; it is equipped with self-locking universal wheels, so that during the rust removal process, Avoid the movement of the derusting device due to rotation, increase the stability of the derusting device, and at the same time make the derusting device easy to move and improve work efficiency; the base is equipped with a removable cleaning box and a first circular through hole, so that the workpiece The iron filings after derusting are easy to clean; however, this technical scheme uses a wire brush to polish the workpiece to derust, so that the rust at the dead corners of the workpiece cannot be polished, and at the same time, this technical scheme cannot perform derusting in large quantities, making the The descaling process is inefficient, which in turn limits the solution
