| 摘 要： | 采用HyperXtrude专业铝型材挤压成型有限元软件系统,以多边型空心铝型材为研究对象,对其稳态挤压成型过程进行数值模拟,计算结果发现初始模具结构中金属材料流速严重不均匀.通过增设导流槽、合理布置分流孔和调整工作带长度等措施,获得了较为理想的模具结构,同时提高了模具的寿命.

| Abstract: | Taking a polygon hollow aluminum profile as research object,using the professional Finite Element analysis software HyperXtrude,the steady extrusion process was numerically simulated and analyzed.The result show that the velocity of metal flow is not uniform in initial mold structure.Using the measures of adding diversion trench,rationally arranging holes and adjusting die workspace length,the ideal die structure can be obtained and the service life of the die is improved. |
