摘要:

 针对企业实际生产中遇到的六角法兰面螺母冲孔过程中下冲头磨损严重的问题,利用有限元软件DEFORM-3D对法兰面螺母的冲孔过程进行了仿真模拟,重点进行模具参数方面的优化。建立了Archard磨损模型及SCM435钢的本构模型,基于动态模拟结果,直观地分析了冲孔过程中下冲头的磨损机理。结合仿真结果,以下冲头的磨损量为优化目标,选取若干关键因素作为仿真试验因素,建立了多水平的正交试验,依据仿真结果分析了各试验因素的关键性,通过极差及方差分析获得了六角法兰面螺母冲孔过程的最优工艺参数以及下冲头的最优结构,并根据最小磨损量预估了下冲头的使用寿命。最后,进行了模具的试制及试模生产,获得的六角法兰面螺母质量较好,下冲头磨损速度明显降低,有效地降低了企业的成本。

 In view of the serious wear for lower punch during the punching process of hexagon flange nut in the actual production of enterprise, the punching process of flange nut was simulated with the finite element software DEFORM-3D, and the optimization of die parameters was focused on. The Arcard wear model and the SCM435 steel constitutive model were established. Based on the dynamic simulation results, the wear mechanism of lower punch in the punching process was analyzed intuitively. Combined with the simulation results, taking the wear amount of lower punch as the optimization goal and selecting some key factors as the simulation test factor, the orthogonal test of multiple levels was established. According to the simulation results, the key of each experimental factor was analyzed. By range and variance analysis, the optimal process parameters and the optimal structure of lower punch were obtained during the punching process of hexagon flagenuts, and according to the minimum wear amount, the service life of lower punch was forecasted. Finally, according to the mold trial production and die test production, the quality of hexagonal flange nut is good, the wear speed of lower punch is reduced significantly, and the cost of the enterprise is reduced effectirely.
