水溶性电火花电解复合加工工作液的制备及其对割缝效果的影响
|
摘要
割缝筛管是机械防砂的重要设备,试验采用电火花电解复合加工的新方法对割缝筛管进行加工。针对传统的水基工作液加工效率低,而常用的煤油闪点低,安全性差等缺点,试验研制了一种新型电火花电解复合加工水溶性工作液。采用正交试验确定最佳基础工作液,并添加爆破剂蔗糖、电解质等,研究对复合加工的影响规律,并与机油加工的效果进行对比。结果表明,在温度为30℃的条件下,纯水、聚乙二醇400及三乙醇胺的比例为m(水)∶m(聚)∶m(三)=11∶11∶3时,基础工作液10%(质量分数)稀释液性能最优。在其基础上加入35g蔗糖,1g NaNO3和0.25gNaCl可以得到最佳的加工效果。与机油加工工作液相比表面粗糙度减小,加工效率降低且缝宽有所增加,清洁性与安全性提高。
Slotted screen is an important equipment for mechanical sand,a new method via electrical discharge machining(EDM) combined electrochemical machining(ECM) is used to manufacture the screen. Aiming at the shortcomings of traditional water based working fluids,such as low processing efficiency,low kerosene flash point and poor safety,a new water-soluble working fluid for EDM combined machining was developed. The best basic working fluid was determined by orthogonal test,and sucrose,electrolyte and so on were added in the compound processing,and the difference between the compound processing and the oil processing was compared. The results showed that at a temperature of 30 ℃ the ratio of pure water,polyethylene glycol 400 and triethanolamine was of11 ∶ 11 ∶ 3,and the performance of the basic working fluid with a mass fraction of 10% was the best. The best processing effect can be obtained by adding 35 g sucrose on the basis of 1 g NaNO3 and 0.25 gNaCl. Compared with the working fluid of oil processing,the surface roughness was reduced,the processing efficiency was reduced and the width of the seam was increased,and the cleanness and safety were improved.
