摘要：Based on split-ring experiment for cylindrical drawing cups, the springback property of aluminum alloy cylindrical drawing cups with different process parameters was investigated by orthogonal test design method in conjunction with numerical simulation during warm forming process, and a finite element model was established for warm forming of aluminum alloy. The effect of process parameters including initial forming temperature of blank, punch velocity, friction coefficient, blank holder force, punch radius, die radius and clearance between punch and die on springback was investigated by numerical simulation of cylindrical drawing cups based on orthogonal test, and the optimal combination of process parameters was determined. The results indicate that, in view of the significant level of the effect of process parameters on springback, the effect of initial forming temperature of blank is the strongest, and increasing initial forming temperature of blank can evidently reduce springback. Blank holder force takes the second place, followed by die radius, clearance between punch and die and friction coefficient, while the effects of punch velocity and punch radius are almost negligible. © 2016, Editorial Board of Journal of Huazhong University of Science and Technology.
