An electrolysis-electrodeposition processing device and method for repairing SLM molded parts

Abstract

The invention discloses an electrolysis-electrodeposition processing device for repairing SLM molded parts, which includes first and second electromagnetic reversing control valves, a small six-axis mechanical arm, a computer control system, and a workbench; the first and second electromagnetic reversing control valves The working position of the directional control valve has four oil ports A, B, P, and T; the front end of the small six-axis mechanical arm is fixed with a nozzle, and the tail of the nozzle is connected to the oil port B of the first electromagnetic reversing control valve through the infusion pipeline; The oil ports T, P, and A of an electromagnetic reversing control valve are respectively connected to the first, second, and third solution tanks through the infusion pipeline, and the first, second, and third solution tanks are respectively connected to the second electromagnetic reversing tank through the infusion pipeline. The oil ports T, P, and A of the control valve are connected. Based on the device, the surface defects of the molded parts are repaired, and the surface of the molded parts is processed by jet electrolysis and jet electrodeposition respectively. Through the combination of these two processing methods, the surface quality of SLM molded parts is improved.
