Cathode system and method for nesting material electrolytic machining in low temperature environment

Abstract

The invention provides a low-temperature environment sleeve material cathode electrolytic machining system and method, and belongs to the technical field of electrolytic machining. The cathode systemis mainly composed of a cathode piece, a cathode body, a heat insulation sleeve, an insulation sleeve and a refrigerating agent cavity sleeve. The method comprises the steps that the insulation sleevegradually sleeves the work piece, the refrigerating agent is transmitted to the part, located in the periphery of a processed part of the work piece, of the refrigerating agent cavity sleeve to forma local low-temperature region which is distributed in gradient in the periphery of the processed part of the work piece. The system and method have the advantages that the conduction rate of stray electrolyte is reduced with the help of the system and the method, the stray corrosion of processed region of the work piece is reduced, and therefore the shaping precision of the work piece is improved.

Description

technical field [0001] The invention relates to the technical field of electrolytic processing, in particular to a cathode system and method for electrolytic processing of materials in a low-temperature environment. Background technique [0002] With the increasing requirements for material properties in national defense, aviation and aerospace industries, difficult-to-machine materials such as titanium alloys and high-temperature alloys are more and more widely used in them. Traditional mechanical processing methods have problems such as easy tool wear, low processing efficiency, poor surface processing quality, and high processing costs in difficult-to-machine materials. Compared with traditional mechanical processing, electrolytic machining has the advantages of simple processing process, high processing efficiency, no tool wear, no residual stress, etc., and has been widely used in the manufacturing process of difficult-to-machine materials. As an efficient electrolytic...
