摘要为了改善传统闭式模锻件的恶劣使用条件，平衡其良好的充型性和较长的模具寿命，在肘形件热挤压模中引入了一种新的飞边棱，即阻力壁，它综合了闭式和开式模锻的优点。采用部分析因设计方法，研究了结构参数对型腔填充、最大成形载荷和圆角区磨损深度的主要影响，并进行了有限元模拟。研究并优化了壁高、间隙、倾斜度、齿根圆角、飞边厚度和桥宽六个实验因素的影响。在此基础上，得到了主效应排序表，并通过生产试验进行了验证。
Abstract In order to improve the severe service conditions and balance the needs between the better cavity filling and longer die life of traditional closed die forgings, a new flash land named by resistance wall, which integrated the advantages of closed and open die, was introduced into knuckle hot extrusion dies. The fractional factorial design, , was employed to evaluate main effects of the structural parameters on the cavity filling, the maximum forming load and wear depth in bar fillet area, which was simulated by finite element method. Effects of six experimental factors: wall height, clearance, inclination, root fillet, flash thickness and bridge width were studied and optimised. Based on the results, a sort table about main effects was obtained and validated by production trials.
