摘要

To take velocity uniformity of working tape of metal outflow extrusion die as the goal,to ensure the high quality forming, using normal extrusion process to set the corresponding process parameters,using HyperXtrude software to optimize extrusion die working tape shape and parameters,extrusion technology and die match each other,practical application feasibility of the numerical value application are put forward,to guide the actual mass of die manufacturing and aluminum extrusion production. At the same time,the computer numerical simulation research method of “virtual die testing” effect can reduce the aluminum design research and development production cycle,save the actual production test times,improve production efficiency and yield,lower profile extrusion production cost,improve aluminum profile production economic benefits.%以金属流出挤压模具工作带的流速均匀性为目标，以确保高质量成形为目的，采用正常挤压工艺设置相应工艺参数，使用HyperXtrude软件对挤压模具工作带形状和参数进行优化，提出挤压工艺与模具相互匹配、具备实际应用可行性的数值化应用解决方案，用以指导实际批量化的模具制造和铝型材挤压生产。同时，此项计算机数值模拟分析研究方法产生的“虚拟试模”效果，可以减少铝型材设计研发生产周期、节省实际生产试模次数、提高生产效率和成品率、降低型材挤压生产成本，提高铝型材生产经济效益。
