摘要
通过选取不同的砧宽比和压下率参数,模拟上下宽V型砧拔长变形,运用有限元方法分析坯料截面最大主应力变化,选取合理的上下宽V型砧拔长工艺参数,提高锻件质量。
By selecting different anvil width ratio and reduction ratio, the deformation of drawing out process with upper and lower V shape wide anvils has been simulated, and the variation of maximum principle stress on the section of blank has been analyzed by the finite element method. The quality of forgings can be improved by selecting the rational parameters of drawing out process with upper and lower V shape wide anvils.
