锻造过程的预成形设计是提高锻造质量和降低产品成本的一个极其重要的方面 ,基于刚-粘塑性有限元法的正反向模拟技术能够从最终的锻件形状直接得出坯料的预成形形状 ,通过改善设计制坯操作来减少作为飞边的材料浪费。文中介绍了履带链轨节锻造的常规工艺 ,说明了目前履带链轨节锻造中存在的问题 ,阐述了有限元法、预成形设计思想和正反向模拟技术以及它们在履带链轨节锻造中的应用
Forging process pre-forming design is to improve the quality of forging and reduce product cost is an extremely important aspect, based on rigid-viscoplastic finite element method of positive and negative simulation technology can be derived from the final forging shape of the blank directly into the pre-formed shape, Reduce material waste as a flash by improving design blanking operations. In this paper, the conventional process of forging of track link section is introduced, the existing problems of track link section forging are described, and the finite element method, preform design idea and forward and reverse simulation technology and their application in track link section forging Applications
