Overall process linear flow flexible protection sleeve material electrochemical machining device and method

Abstract

The invention relates to an overall process linear flow flexible protection sleeve material electrochemical machining device and method, and belongs to the field of electrochemical machining. The device is formed by a cathode assembly and an auxiliary assembly. The flow mode of the electrochemical machining method is an overall process linear flow manner, electrolyte flows from the front edge of a blade to the back edge of the blade, and a flow field is in a convergence state; the cathode assembly moves and drives the auxiliary assembly to move at the same time, the electrolyte is supplied in a manner of aligning at a machining area all the time, and it is ensured that the flow field is stable; and in the electrochemical machining process, a flexible insulation block seals a machined area, and scattered corrosion caused by the fact that the electrolyte flows to the machined surface is effectively reduced. By means of the overall process linear flow flexible protection sleeve material electrochemical machining device and method, the sleeve material electrochemical machining flow field stability is better improved; the taper of the blade is reduced, and the machining accuracy is improved; and the surface quality is improved.

But since there is still electrolyte entering the machined surface from the gap between the insulating cavity and the machined area, the machined area is still affected by stray corrosion

[0004] Although the traditional positive punching nesting electrolytic machining has the advantage of simple fixture design, its flow characteristics are diffuse flow, and there are obvious flow lines on the processing surface, whi
