Embodiment Construction

[0023] Below in conjunction with the operation steps of workpiece processing, further illustrate the working method of the present invention:

[0024] (a) Start the heating system, and when the temperature of the electrolyte is heated to 30°C, start the constant temperature system;

[0025] (b) Start the electrolyte circulation system, and pass the electrolyte through the liquid inlet;

[0026] (c) Activate the DC power source to energize the tool cathode and workpiece anode;

[0027] (d) Start the CNC machine tool operation program, the anode workpiece is fed along the axis of the workpiece, and in the electrolyte environment, the tool cathode gradually removes the anode workpiece material through electrolytic corrosion. With the axial feed of the workpiece, the dual-blade contour machining edge on the tool cathode can produce two blades with different contours at one time.

[0028] (e) Rotate the workpiece at a certain angle, feed the workpiece again, and process an adjace...

Abstract

The invention discloses a dual-blade sleeve electrolytic processing device and a processing method thereof, and belongs to the field of electrolytic processing. A clamp device comprises a cathode mounting clamp and a chuck fixing clamp. For an integral component with big and small blades, an integral type tool cathode of two characteristics is designed, and the tool cathode is axially fed to realize processing of workpieces; dual-runner flow-equalizing liquid supply flow fields are designed, so that a sufficient electrolyte solution is guaranteed in a two-blade processing area; an insulated sleeve in the cathode base is designed, and a protective sleeve for blades at adjacent two sides is designed, so that processing blades and processed blades are prevented from a stray current corrosionphenomenon; an insulating layer is coated on the front edge end surface of the cathode, and an insulating block is added on the tail part of the rear edge, so that a cathode non-processes area is isolated from the workpieces, and therefore, a base body of a workpiece disc body and the tail edges of the blades are protected.

Description

technical field [0001] The invention relates to the field of electrolytic machining, in particular to a clamp device for electrolytic machining of double-blade sleeves and a machining method thereof. Background technique [0002] Electrochemical machining is the removal of workpiece material based on the principle of anodic dissolution in an electrolytic cell. 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 formed tool cathode is fed toward the workpiece anode, and the workpiece material is gradually dissolved to complete the machining. Therefore, electrolytic machining has the characteristics of no tool cathode loss, high processing efficiency, no cutting stress, and basically not limited by the mechanical properties of materials, and is widely used in the fields of aviation and aerospace. [0003] In the article "Summary of High-speed Sleeve Shape Using...
