Embodiment Construction
[0029] Below in conjunction with the operation steps of workpiece processing, further illustrate the working method of the present invention:
[0030] (a) Start the heating system, and when the temperature of the electrolyte is heated to 30°C, start the constant temperature system;
[0031] (b) Start the electrolyte circulation system, and pass the electrolyte through the liquid inlet;
[0032] (c) start the electrolysis power source to energize the tool cathode and workpiece anode;
[0033] (d) Start the operation program of the CNC machine tool, and feed the workpiece along the axis direction. In the electrolyte environment, the tool cathode gradually removes the anode workpiece material through electrolytic corrosion; with the axial feed of the workpiece, the combined tool cathode The cross-blade contour machining edge on the top can process two spaced blades with different contours at one time;
[0034] (e) After the processing is completed, cut off the power supply, sto...

The invention discloses a blade-crossing cathode pulse dynamic trepanning electrolytic machining device and method, and belongs to the field of electrolytic machining. The device mainly comprises a combined blade-crossing cathode and a cathode mounting clamp. For an integral component with alternating large and small blades, a blade-crossing cathode is designed, the blade-crossing cathode comprises a large blade cathode and a blade cathode which are installed at the two front ends of a cathode base respectively, and a set of large and small blades are arranged between the two cathodes in a crossing mode. In the machining process, a workpiece is fed towards a tool cathode in the axial direction, the cathode vibrates in a reciprocating mode, a pair of large and small blades spaced by a set of blades is machined, and simultaneous machining of the two blades is achieved; and pulse current is introduced while the cathode vibrates, so that pulse vibration optimized and coupled pulse dynamic machining is realized. Two separated independent flow channels are designed to supply liquid to the large and small blades correspondingly, intersection of two flow fields can be prevented, the uniformity of the flow fields is improved, and it is guaranteed that sufficient electrolyte exists in the machining area of the two blades.
Description
technical field [0001] The invention relates to the field of electrolytic machining, in particular to an electrolytic machining device and method for dynamic nesting of cathode veins across blades. Background technique [0002] Electrochemical machining is the removal of metal workpiece material based on the principle of electrochemical anodic dissolution. Before the start of electrolytic machining, a high-speed flowing electrolyte is introduced into the area to be processed; during the electrolytic machining process, the cathode of the forming tool is fed toward the anode of the workpiece, and the material of the workpiece is gradually dissolved to complete the machining. Electrolytic machining has the characteristics of no loss of tool cathode, high processing efficiency, no cutting stress, and basically not limited by the mechanical properties of materials. It is used in aerospace, weapons and molds and other industries. [0003] With the continuous improvement of aero-e...
