Results show that compare with cogging process using common flat anvil and common V anvil, using concave flat anvil and concave V anvil can increase the deformation at the center of the billet > improve the stress state of the center part and greatly decrease t.
根据大锻件锻造工艺发展的现状和存在的问题,提出了利用凹面砧进行拔长的两种新工艺—凹面平砧锻造法(即CFAF法)和凹面V砧锻造法(即CVAF法),并利用大型非线性有限元软件ANSYS对两种工艺进行了数值模拟。
