Rotary body surface concave-convex array structure double-rotation-speed rotary printing electrolysis system and method

Abstract

The invention discloses a rotary body surface concave-convex array structure double-rotation-speed rotary printing electrolysis system and method, and belongs to the technical field of electrolytic machining. The machining method is mainly used for machining the concave-convex array structure on the surface of a rotary body part and is characterized in that a tool cathode is of a rotary body structure with the diameter approximate to 1 / n times that of a rotary body workpiece to be machined, and array boss structures or window structures with the number 1 / n times that of concave cavities or boss structures on the surface of the rotary body workpiece are arranged on the surface of the tool cathode. In a machining process, a workpiece anode rotates at a certain angular speed, the tool cathode rotates in a reverse opposite at an angular speed n times that of the workpiece anode, meanwhile, feeding is conducted in a radial direction of the rotary body workpiece, and therefore boss or cavity arrays with the number n times that of window or boss structures on the surface of a workpiece cathode are machined on the surface of the workpiece anode. According to the method, the small-size tool cathode of a simple structure is adopted, and one-time efficient machining of the concave-convex rotary body part with complex arrays can be achieved.

Description

Technical field[0001]The present invention proposes a method of rotating the surface of the surface of the steering body, which is a method of electrolysis and processing technology.Background technique[0002]The rotary body parts with array incurred structure are key components in the fields of aerospace, aerospace, mining, generally using traditional machining methods. The surface of these rotary body has an array of uneven structures, which typically have a high temperature alloy or a high hardness alloy. When using conventional machining, the tool loss is large, the processing cycle is long, the processing cost is high, and the residual stress after processing is large, and the workpiece It is easy to deform, and a complex heat treatment process is required to eliminate deformation. With the development of new materials, higher hardness, more difficult to cut materials is used for the manufacture of rotary body parts, and their structures also use integral design, and the difficu...
