高硬度合金钢材料具有优异的力学性能,被广泛应用于加工等领域.本文以中合金钢异形型面零件为研究对象,首先,针对异形型面零件电解加工装置中的电解液间隙流场设计了三种有着不同的引流段和导流段、进液孔与出液孔数量和位置的电解液流场间隙结构模型设计.其次,对三种电解液流场间隙结构进行多物理场耦合仿真研究分析,通过对电解液流动形式进行分析确认侧流式供液,并对电解加工间隙中的电解液流速、温度、气泡率、压力进行分析优选最佳的电解液流场间隙结构.最后,根据所优选的间隙结构进行电解加工装置设计.本文从工具阴极设计及流场优化方面上提高了电解加工过程中的稳定性和加工成型精度,有效地缩短了电解加工阴极结构研制的时间周期和成本,为电解加工在异形型面加工的应用提供工艺技术参考,为行业技术进步起到了巨大的推动作用.
Abstract
High-hardness alloy steel materials exhibit outstanding mechanical properties and find extensive applications in various processing fields.This study focuses on the electrochemical machining of complex-shaped surface parts made of medium-alloy steel.Initially,three different gap structure models are designed for the electrolyte flow field in the electrochemical machining device,featuring varying guide sections,flow sections,inlet and outlet hole configurations.Subsequently,a multi-physical field coupled simulation analysis is conducted to evaluate these models.The side-flow supply method is determined through an analysis of electrolyte flow characteristics,including velocity,temperature,bubble rate,and pressure within the electrochemical machining gap.Based on this analysis,the best gap structure model is selected for optimization.Finally,the electrochemical machining device is designed based on the optimized gap structure to enhance stability and processing accuracy while reducing research cycle and cost associated with cathode structure development.This work provides valuable process technology insights for applying electrochemical machining in complex-shaped surface processing and contributes significantly to industry advancement.
