Abstract

The invention relates to a machining method and device for axial purge electrolytic wire cutting assisted by workpiece reciprocating motion, and belongs to the technical field of electrochemical machining. The machining method and device for the axial purge electrolytic wire cutting assisted by the workpiece reciprocating motion is mainly characterized in that a workpiece with large thickness is cut and machined by adopting the axial purge electrolytic wire, and cutting motion is conducted on wire electrode by a workpiece while the reciprocating motion is conducted on the workpiece by the workpiece along the feeding direction and the wire electrode axis direction. The method of the workpiece reciprocating motion is adopted to change the distance between the workpiece and the wire electrode, and the distance between the workpiece and a nozzle, fast flowing of an electrolytic solution in a long and narrow feeding end surface machining clearance is facilitated, renewal of the electrolyticsolution and removal of electrolysate are accelerated, the difference of the electrolytic solution flow velocity is shortened, and the machining efficiency and machining accuracy of electrolytic cutting are improved.

Description

technical field [0001] The invention relates to a workpiece reciprocating motion assisted axial flushing electrolytic wire cutting processing method and device, belonging to the technical field of electrochemical processing. Background technique [0002] Aeroengine blisk mortise, blade tenon, precision transmission gear and other ruled surface structural parts are mostly processed by cutting technology, while electrolytic wire cutting uses metal filaments as tool cathodes, and uses metal to generate electricity in the electrolyte. The principle of electrochemical anodic dissolution, a cutting technology for processing and forming metal materials, has the advantages of high processing precision, no processing residual stress, no recasting layer, no tool loss, etc., so it is suitable for high-quality ruled surface structure parts Precision cutting processing. [0003] However, because the kerf of electrolytic wire cutting is too narrow, it is difficult for fresh electrolyte t...
