Abstract

The invention provides an electrolytic machining cathode device for freezing protection sleeve material and a processing method, and belongs to the technical field of electrolytic machining. The cathode device is mainly composed of a cathode head, a cathode block, a freezing block and a coolant bag body. In the sleeve material electrolytic machining method, the coolant bag body surrounds the periphery of a protection cavity in the middle of the freezing block, the machined part of the workpiece gradually extends into the protection cavity in the middle of the freezing block, a coolant is fed from the inlet end of the coolant bag body and flows out from the outlet end of the freezing block, and the stray electrolyte in the middle protection cavity of the freezing block is frozen. Accordingto the electrolytic machining cathode device, stray corrosion caused by stray electrolyte on the machined surface of the workpiece is reduced, the taper of the workpiece is reduced, and the surface quality of the workpiece is improved.

Description

technical field [0001] The invention relates to the field of electrolytic processing, in particular to a cathode device and a processing method for electrolytic processing of freezing protection sleeve materials. Background technique [0002] Electrolytic machining has high processing efficiency and low processing cost in mass forming of high-strength and high-hardness materials such as high-temperature alloys and titanium alloys, and is therefore widely used in the processing of difficult-to-machine materials in military, defense, and aerospace manufacturing middle. [0003] Electrolytic machining is based on the electric field between the cathode and the workpiece, the electrolyte flow field and the principle of electrochemical dissolution to etch the metal workpiece. During the processing, the cathode device is continuously fed to the workpiece, and the surface material of the workpiece is continuously etched and finally formed. It has a wide range of processing. , There...
