Description
Technical field
The present invention relates to a kind of Electric Discharge Wire-cutting Technology, especially a kind of Wire EDM working solution feed system, specifically a kind of aqueous water of producing from normal temperature air is as the method for Wire EDM working solution preparation solvent and device.
Background technology
Along with the development of China's machinery manufacturing industry, electric spark linear cutting machine has become the important process equipment of the sector, and Wire EDM also plays a part to be difficult to substitute in the processing of a large amount of irregular part and difficult-to-machine material.
The electric discharge processing of Wire EDM working solution (hereinafter referred to as working solution) to Wire EDM plays vital effect.Spark discharge must carry out in the liquid medium with certain insulating properties, the insulating properties of working solution not only can compress discharge channel, make the concentration of energy of spark discharge in a smaller region to strengthen galvanic corrosion effect, the deionization also contributing to discharge channel completes within the extremely short time, prevents the generation of arc discharge.If the insulating properties of working solution are poor, then be unfavorable for forming discharge channel, electrolysis can be strengthened, consume discharge energy, weaken the ablation effect of spark discharge, electrolysis not only can reduce stability and the efficiency of processing, also can increase work pieces process face metamorphic layer, surface hardness is reduced, occurs micro-flaw, reduce the surface quality of workpiece.The insulating properties of discharge medium depends primarily on ion concentration wherein, and the height of effects of ion concentration is presented as the size of electrical conductivity.
Working solution is by working solution stoste and working solution solvent composition, and solvent is as important component part, and its performance of electrical conductivity to joined working solution has a great impact.The best solvent using distilled water (electrical conductivity=1.0 μ S/cm) as working solution in theory, generally adopts running water to prepare working solution as solvent in actual applications.For Hangzhou, running water can meet the processing request of Wire EDM substantially, Hangzhou that coexists is got different water source and is carried out sampling, testing (when winter temperature is 7 DEG C), running water electrical conductivity is about 23 μ S/cm, underground electrical conductivity of water is about 53 μ S/cm, and self-control condensation electrical conductivity of water is about 2.3 μ S/cm.The Conductivity Ratio running water of known condensed water want a little order of magnitude, with distilled water closely, so adopt the condensed water less than running water electrical conductivity more can contribute to improving the technological effect of the electric discharge processing of reciprocal Wire EDM as working solution solvent.
China is vast in territory, and each department water quality is different, and abundance of water district mostly uses surface water, water deficient regions uses deep-well underground water substantially, in water, contained number of ions concentration difference is very large, and this difference will cause spark discharge processing technology effect to have very big-difference, and even causing can not normal process.For the South and the North: south main employing surface water carries out process and produces running water, and water quality is softer, and contained ion concentration is low, and electrical conductivity is lower, generally can be used as working solution solvent and uses; The north many employings phreatic water carries out process and produces running water, and water quality is comparatively hard, and contained ion concentration is high, and electric discharge processing effect is very bad.Working solution ion concentration contained by solvent of different solvents preparation is different, make processing stability, efficiency and workpiece surface quality variant, also can affect the service life of wire electrode, and the different guiding discharge gaps of solvent intermediate ion concentration are also different, SERVO CONTROL also can be affected, and makes technology library parameter be difficult to realize consistent processing effect.And condensed water intermediate ion concentration can not change because of the difference of region, and adopt condensed water to be Wire EDM working solution preparation solvent, avoid the difference of each department source quality, while improving Wire-cut Electrical Discharge Machining effect, also improve the applicability of the uniformity of technique, stability and lathe.
The lifetime of conventional to-and-fro thread feed electric spark wire-electrode cutting machine working solution is generally 100 hours, need frequently to change working solution, and adopt traditional way to be first topple over waste liquid with a dead lift, then manually get new water and prepare working solution again, process is loaded down with trivial details, waste time and energy; The spill and leakage of useless working solution can affect the clean of production environment simultaneously; Current most of factory does not have special sewage-treatment plant, adds human factor, and the working solution of inefficacy very easily directly discharges as waste liquid, causes environmental pollution.If can useless working solution all evaporate produce condensed water be re-used as working solution solvent use, both the trouble of water intaking can have been saved, reduce the labour intensity of operating personnel, increase work efficiency, processing etched matter can be made again to deposit in solid form, avoid environmental pollution, also for waste reclamation creates advantage.
