Abstract

The invention discloses a cathode for free-form-surface-cavity electrochemical machining. The cathode comprises a cathode body and a cathode head, wherein an electrolyte inflowing channel is formed inthe cathode body, a liquid-inlet inflowing channel and a liquid-outlet outflowing channel are formed in the cathode head, one end of the liquid-inlet inflowing channel is communicated with the electrolyte inflowing channel, the other end of the liquid-inlet inflowing channel leads to a workpiece, one end of the liquid-outlet outflowing channel leads to the workpiece, and the other end of the liquid-outlet outflowing channel is leaded out of the side face of the cathode head at the upper portion of the workpiece. A free-form surface comprises a protruding part and a concave part, the liquid-inlet inflowing channel is formed in the protruding part of the free-form surface, and the liquid-outlet outflowing channel is formed in the concave part of the free-form surface. According to the cathode for free-form-surface-cavity electrochemical machining, inflowing and outflowing of electrolyte can be simultaneously achieved, the integrity of a flow field is guaranteed, dead water zones in machining gaps can be effectively eliminated, and the short circuit phenomenon caused by a unsmooth flow field is prevented.

Description

technical field [0001] The invention relates to a cathode structure, in particular to a cathode for electrolytic processing of a free-form surface cavity. Background technique [0002] The Chinese utility model patent whose authorization notification number is CN 206887238 U discloses a kind of anti-rubber sleeve aging-proof electrolytic cell cathode cage, which includes a plurality of stainless steel bars and a stainless steel The cathode handle of the steel bar and the rubber sleeve used for insulation are characterized in that: a plurality of stainless steel steel bars are combined into a squirrel cage structure, and the insulating sleeve is provided with an inner lining, and the inner lining is provided with a through hole in the middle The cross-section is a "T"-shaped gyratory structure, and its bottom is matched with the rubber sleeve. The utility model sets an inner liner made of PTFE pipe fittings in the rubber sleeve. The inner liner has better high temperature re...
