Abstract

The invention discloses an electrochemical machining device comprising a machine tool and a solution supplying system, wherein the machine tool is used for clamping a workpiece and driving a workpiece cathode to move relative to the workpiece in the X-axis direction, the Y-axis direction and the Z-axis direction, and the solution supplying system is used for supplying solution to the workpiece. The electrochemical machining device further comprises a pressure pulse system. The pressure pulse system comprises an air compressor, a gas pulse generator and a gas-liquid mixer, wherein the air compressor, the gas pulse generator and the gas-liquid mixer are sequentially connected. The gas-liquid mixer is connected with the liquid supplying system, mixes gas and liquid intermittently and outputs the gas and liquid mixture to the workpiece cathode. By the adoption of the electrochemical machining device, the pressure pulse system is arranged, and gas is intermittently input and mixed with the work solution, a liquid-state working solution and a gas-liquid two-phase work solution alternately perform; and when the gas-liquid two-phase work solution fills a machining interval, fine bubbles in the electrolytic solution approaches a machined surface and crack due to blockage, in the crack process, quite high pressure and micro-jet are generated, a metallic oxide attached layer prone to generation during electrochemical machining is effectively removed, and therefore the stability of electrochemical machining is improved.

Description

technical field [0001] The invention relates to the technical field of material processing, and more specifically relates to an electrolytic processing device. Background technique [0002] Electrochemical Machining (ECM) is a method based on the dissolution and removal of materials in the form of "ions" from the anode metal. The electrolytic machining process has the advantages of high processing efficiency, no loss of tools, no heat-affected layer on the surface of the workpiece after processing, smooth structural surface, no internal stress, no cracks, and processing is not limited by the hardness of the material, so it is widely used. [0003] In electrolytic machining, the flow field in the machining gap is not only directly related to the accuracy of electrolytic machining and the quality of the surface, but also determines whether electrolytic machining can be implemented. There are three main forms of electrolyte flow, positive flow liquid supply, side flow liquid s...
