Problems solved by technology

[0002] Traditional EDM uses oil as the discharge medium, which has stable processing and high efficiency, but there are also some disadvantages: the gas decomposed by pyrolysis is harmful to the human body and the environment; there is a fire hazard; the waste after use is harmful to the environment; and the use cost is high ; There are heat-affected layers such as white layer on the processed surface
Oil-based working fluid is used in EDM, but there are some problems, such as large heat loss, poor chip removal effect, easy to form white layer due to rapid cooling, and easy to rust the machine tool
In the 1990s, the Kunieda Masonic scholar of Tokyo University of Agriculture and Technology proposed and realized the gas dielectric EDM, which effectively solved the above-mentioned shortcomings of the oil-based working fluid, but the gas dielectric discharge gap is very small, and the requirements for the machine tool servo system are high. The processing is unstable when using ordinary EDM machine tools, which increases the probability of abnormal discharge and reduces the effective pulse utilization rate, so the processing efficiency is low

Abstract

The invention discloses an electric spark liquid atomizing nozzle and belongs to the technical field of electric spark machining. The electric spark liquid atomizing nozzle comprises a nozzle body. The nozzle body comprises a hollow pipe for installation of an electrode. The nozzle body is provided with a sealed upper end cover and an open lower end. The hollow pipe penetrates the nozzle body and stretches to openings formed in the lower end. An annular partition is arranged in the nozzle body to divide the nozzle body into a liquid chamber and a gas chamber. A liquid inlet and a gas inlet are formed in the upper end cover, and mixing chambers are arranged at the openings in the lower ends of the liquid chamber and the gas chamber. Compared with the prior art, the atomization state can be improved, then the discharge gap and discharge channel configuration is changed, the surface quality of a workpiece is improved, the removal rate of electric corrosion products is increased, the machining capacity of an existing electric spark machine tool is further mined, and high efficiency of the electric spark machining technology is achieved.
