摘要
以Dynaform为模拟分析平台,对典型圆筒件拉深成形过程进行了模拟。用正交实验的方法评定了压边力、冲压速度、凸凹模间隙三个因素对零件成形质量的影响,并得到一组优化的参数值。圆筒件拉深成形相关参数的最优值压边力为20kN,冲压速度为2000mm/s,凸凹模间隙为1.1mm。
In this paper,the forming process of a typical cylinder part is simulated by the platform of dynaform.The influence of blank holder force（BHF）,punching speed and clearance between punch and die on the quality of forming part is assessed by the orthogonal experimental method.The value of BHF of 20kN,punching speed of 2000mm/s and clearance between punch and die of 1.1mm which are the optimized parameters value are obtained.
