添加络合剂电解加工小孔的实验研究
|
摘要
本文通过向电解液中加入络合剂与常规电解加工进行了侧面间隙、加工效率的对比实验,对添加络合剂的加工机理以及实验结果进一步分析。实验分析表明,和常规电解加工小孔相比,添加络合剂使得加工间隙内气、液、固三相流场更趋于气、液两相流场,改善了流场分布的均匀性,从而使得加工过程中侧面间隙变小,加工精度和加工效率得到提高。
The comparison of side gap and processing efficiency is carried out by adding complexion agent to the electrolyte and conventional electrolytic processing, and the processing of adding complexion agent is carried out. The mechanism and experimental results were further analyzed. The experimental analysis shows that compared with the conventional electrolytic processing of small holes, the addition of complexion agent makes the gas, liquid and solid three-phase flow fields in the machining gap more inclined to the gas and liquid two-phase flow field, which improves the uniformity of the flow field distribution. The side gap becomes smaller during the processing, and the processing precision and the processing efficiency are improved.
