Embodiment Construction

[0021] figure 1 In the process, under the action of the pressure difference formed by the vacuum and the atmospheric pressure 3, the electrolyte 2 enters the electrolyte channel 23 of the electrode 5 from the inter-electrode processing area and then enters the vacuum chamber 24 to complete the electrolyte update for the processing gap. The electrode 5 can be coated with an insulating coating 4 to insulate the side walls to improve processing accuracy.

[0022] figure 2 In the shown vacuum reverse flow electrolytic machining device, the power source 22, the machine tool spindle 17, the feeding device 25 and the electrode fixture 7 form the machine tool body. Motion control card 18, data acquisition card 20, Hall current sensor 21 and computer 19 form the control system. In addition, vacuum gauge 8, vacuum pump 9, gas-liquid separation device 10, flow meter 11, liquid storage tank 12, flow control valve 13, liquid supply pump 14, filter 15, and electrolytic cell 6 constitute...

Abstract

The invention relates to a vacuum backflow electrolysis processing method and a vacuum backflow electrolysis processing device which belong to the technical field of electrolysis processing. The method adopts a backflow liquid supply way in the process of electrolysis processing; and electrolyte enters a front gap from a side gap of a processing area to participate in reaction and is finally discharged from an electrolyte passage in a tool electrode. The vacuum backflow electrolysis processing method is characterized in that the backflow liquid supply way is realized by a pumping function of a vacuum generating device. The method and the device are significant for improving the stability and the processing efficiency of electrolysis processing.

Description

Technical field [0001] The vacuum counterflow electrolytic machining method and device of the invention belong to the technical field of electrolytic machining. Background technique [0002] Electrochemical machining (ECM for short) is a process that uses the principle of electrochemical anodic dissolution to etch materials and finally process them into shapes. This process has the characteristics of not being limited by the hardness of the workpiece material, good processing quality, and no loss of tools. It has important applications in aviation, automobile, weapon, mold manufacturing and other industries. [0003] Hole machining is a typical application of electrolytic machining. It is mainly used for hole machining on difficult-to-cut materials, such as hollow cooling turbine blades and guide vanes, which have many small hole structures, especially deep small holes and multi-directional holes. Angle-distributed small holes are very difficult to drill with ordinary mecha...
