Abstract

The invention provides a gas insulation protection jacking electrolytic machining cathode system and machining method. The cathode system is mainly composed of a jacking cathode, a cathode head and a ventilation module. In the jacking electrolytic machining method, an electrolyte laterally flows, and high pressure gas positively flows; and the machined profile of a workpiece gradually stretches into the jacking cathode, the high pressure gas with the pressure being adjustable in real time is blown into the upper end of the ventilation module, forms a uniform gas insulation layer on the surface of the machined profile of the workpiece, blows the stray electrolyte flowing into the cathode towards a gas horizontal channel and is blown out of a ventilation groove of the side of the cathode head. By adoption of the gas insulation protection jacking electrolytic machining cathode system and machining method, the electrolyte in the machined area can be conveniently reduced, the influence of stray corrosion on the workpiece profile is reduced, surface quality of a part is improved, and stability of a flow field in the machining area is improved.

Description

technical field [0001] The invention provides a cathode system and a processing method for electrolytic processing of a gas-insulated protective sleeve material, which belong to the technical field of electrolytic processing. Background technique [0002] Among the various processing methods of difficult-to-machine materials, electrolytic machining has a wide range of applications, especially in the aerospace field, due to its advantages such as high processing efficiency, no loss of processing tools, no residual stress on the processing surface and heat-affected zone, etc. occupies a very important position. In the field of electrolytic machining, the nesting electrolytic machining method is widely used in the machining of components with complex profiles such as equal-section impellers and diffusers due to its fast processing speed and relatively simple cathode design process. [0003] Although there are many advantages in nesting electrolytic machining, there are still m...
