Description
Technical Field
[0001] The utility model relates to the technical field of electrolytic processing equipment, in particular to a cyclonic membrane exchange electrolytic processing equipment. Background Art
[0002] Electrochemical machining (ECM) is a specialized material removal process that utilizes the principles of electrolysis. During ECM, the workpiece, acting as the anode, is connected to the positive terminal of a DC power supply, while the tool electrode, acting as the cathode, is connected to the negative terminal. A certain gap is maintained between the two. Electrolyte flows through this gap, causing the metal on the workpiece to dissolve anodically under the influence of the electric field, thereby achieving the desired shape. Characteristics of ECM include zero tool wear, no heat-affected zone, and suitability for machining difficult-to-machine materials such as carbide and high-temperature alloys. It can also process complex shapes and thin-walled structures.
[0003] During the use of existing electrolytic machining equipment, as the metal material on the workpiece dissolves, a layer of metal material will be wrapped around the cathode material, affecting the activity of the cathode electrode and limiting the electrolysis efficiency of the equipment; at the same time, as the electrolysis work proceeds, the temperature of the electrolyte will rise. If the heat in the electrolyte cannot be discharged in time, it will directly affect the field flow stability in the electrolyte. Utility Model Content
