Embodiment Construction

[0029] The following combined with the operating steps of the workpiece processing, further elucidate the working method of the present invention:

[0030] (a) Start the heating system, wait for the electrolyte temperature to heat to 30 ° C, start the constant temperature system;

[0031](b) Start the electrolyte circulation system and pass the electrolyte from the inlet;

[0032] (c) Start the electrolytic power supply, energize the tool cathode and the anode of the workpiece;

[0033] (d) Start the CNC machine tool operation program, the workpiece is fed along the axis, in the electrolyte environment, the tool cathode will gradually remove the anode workpiece material through electrolytic corrosion; with the axial feed of the workpiece, the cross-blade profile processing blade on the cathode of the combined tool can be processed with two different contours of the interval blade at a time;

[0034] (e) Cut off the power supply after the processing is completed, stop the liquid su...

Abstract

The invention discloses a dynamic nesting electrolytic processing device and method across blade cathode veins, belonging to the field of electrolytic processing. The device mainly includes two parts: a combined cross-blade cathode and a cathode installation fixture. For integral components with alternately large and small blades, a cross-blade cathode is designed, including a large blade cathode and a blade cathode, which are respectively installed at the two front ends of the cathode seat, and a set of large and small blades is straddled between the two cathodes. During processing, the workpiece is fed axially toward the cathode of the tool, and the cathode vibrates back and forth to process a pair of large and small blades separated by a group of blades to realize simultaneous processing of two blades; while the cathode is vibrating, pulse current is introduced to realize optimal coupling of pulse vibration Pulse dynamic processing. Two independent flow passages at intervals are designed to supply liquid to the large and small blades respectively, which can prevent the two flow fields from converging, improve the uniformity of the flow field, and ensure sufficient electrolyte in the processing area of ​​the two blades.

Description

Technical field [0001] The present invention relates to the field of electrolytic processing, specific cross-blade cathode pulse dynamic nesting electrolytic processing device and method. Background [0002] Electrolytic processing is based on the principle of electrochemical anodic dissolution to remove metal workpiece materials. Before the start of electrolytic processing, a high-speed flow of electrolyte is introduced to the area to be processed; during the electrolytic processing, the cathode of the forming tool feeds towards the anode of the workpiece, and the workpiece material is gradually dissolved to complete the processing. Electrolytic processing has the characteristics of no loss of tool cathode, high processing efficiency, no cutting stress and basically no restrictions on the mechanical properties of the material, and is used in aerospace, weapons and molds and other industries. [0003] With the continuous improvement of aero-engine performance, the overall compone...
