摘要
锻造成形过程是一个非常复杂的弹塑性大变形过程,有限元法是用于锻造成形过程模拟中一种有效的数值计算方法。通过数值模拟技术分析叉头锻件改成一模两件的预成形过程,优化预成形模具型腔,获得合理的生产工艺,达到提高原材料利用率和生产班产量,并获得合格终锻件的目的。
The forging forming process is a very complicated process of the evident elastoplasticity deformation,and the finite element method is an effective numerical calculating method used in the process of the forging forming simulation.We have described the preforging process with the numerical simulation technique,optimized the design of mould and confirmed the reasonable techniques to improve the utilization rate of material and output per team.The nicer effect is obtained.
