Abstract

The invention discloses a special-shaped hole electrolytic-machining device and method for active inhibition of stray corrosion. The special-shaped hole electrolytic-machining device comprises a shellbody and a rotational drive mechanism, wherein the shell body is used for fixing parts and forming an closed inner-chamber electrolysis environment for electrolytic machining of the parts, and the rotational drive mechanism is arranged on the central axis of the shell body and penetrates through the shell body to be used for forming shaft fixing and supporting in the inner chamber of the shell body. A processing anode and a processing cathode which are used for electrolytic machining for the parts in the inner chamber of the shell body are arranged on the shell body. A stray corrosion inhibiting unit is arranged on at least one position, in the type hole inlet of a part special-shaped hole, the type hole outlet of the part special-shaped hole and the nonworking side wall of the part, of the shell body, and is used for combing a stray electric field through a low-voltage controllable electric field so as to inhibit stray corrosion in the part electrolytic-machining process. The special-shaped hole electrolytic-machining device can significantly overcome the defect of stray corrosion generated by electrolytic machining and is of great significance to promote the application of electrolytic machining in the field of an aero-engine.

Description

technical field [0001] The invention relates to the technical field of electrolytic machining of aero-engine parts, in particular to an electrolytic machining device for a special-shaped hole that actively suppresses stray corrosion. In addition, the present invention also relates to a method for actively suppressing stray corrosion electrolytic machining of special-shaped holes comprising the above-mentioned device for actively suppressing stray corrosion electrolytic machining of special-shaped holes. Background technique [0002] Electrolytic machining is a special processing method that uses the principle of electrochemical anodic dissolution of metals to realize the processing and molding of workpieces. Compared with other processing methods, electrolytic machining has the following characteristics: 1. Theoretically, the tool cathode has no loss and can be used infinitely; 2. 1. High processing efficiency; 3. Good processing surface quality; 4. Wide processing range, re...
