摘要
利用电化学加工方法实现去除内交叉阵列小孔毛刺,建立电化学去除小孔毛刺的模型,深入研究决定电化学去毛刺加工工艺指标的核心工艺因素——加工间隙,得出加工间隙随时间的变化规律及小孔去毛刺加工时间的各项影响因素。分析间隙内电场、流场情况及其对间隙的影响规律,通过采用阵列电极的方法,实现一次加工对多个小孔毛刺的同时去除。给出试验的加工流程并采用汽车转向器螺杆轴阵列小孔进行了试验,试验结果与理论分析吻合,为理论分析提供了合理的实证。
Use electrochemical machining method for removal the burr of in internal crossed hole arrays,we establish a model of the pinhole deburring and deeply study the core factor,the gap between electrode and workpiece,which decide the process indicators of electrochemical deburring process,the rule of the machining gap with time is influence factors of process time are obtained. Electric field and flow field of gaps and their influence on gaps are analyzed. Deburring of more than one small hole at a processing is realized through the method of electrode array. Process flows are projected. Array holes of screw shafts which apply to diverter automobile hydraulic assistance steering gear are experimented. The results are consistent with theoretical analysis,which provide reasonable evidence.
