摘　　要：悬臂铝型材挤压模在使用一段时间后,型材制品出现了壁厚偏差;采用三坐标测量仪测量下模悬臂的位移偏差,并基于HyperXtrude软件对挤压过程进行了稳态模拟,指出悬臂下塌是造成壁厚偏差的主要原因;通过增加下模厚度,改善出口工作带长度,最终得到了合格的型材产品,并使模具寿命延长。After using cantilever aluminium profile extrusion die for a certain period of time,profile products produced wall thickness deviation.The deviations of low die cantilever were measured by coordinate measuring device.The steady-state extrusion process was simulated based on HyperXtrude software,and it was pointed out that cantilever collapsing was the main reason for thickness deviation.By increasing the thickness of the low die and modifying the exit bearing length,qualified profile products were obtained finally,and the die life was extended.
