Cathode system and processing method for electrolytic processing of insulating shielding sleeve material

Abstract

The invention provides an insulation shielding sleeve material electrolytic machining cathode system and a machining method. The cathode system mainly comprises a sleeve material cathode body, a sleeve material cathode head, an insulation auxiliary block and insulation particles. In the electrolytic method, the flowing mode of electrolyte is side flowing. A workpiece gradually extends into a machined profile protection cavity and pushes the insulation auxiliary block to move synchronously, the surface of the machined part of the workpiece is coated with the insulation particles in the protection cavity in a particle film form. High-pressure gas is blown into the protection cavity from a gas blowing channel and is blown to the machined area at the root of the workpiece. According to the insulation shielding sleeve material electrolytic machining cathode system and the machining method, the electrolyte between gaps of the machined areas of the workpiece can be reduced, a power line on the machined surface of the workpiece is shielded, secondary corrosion of stray currents to the surface of the workpiece is reduced effectively, and the surface quality of the machined profile is improved.
