摘　　要：介绍了采用多向模锻锻制动力工业和石化工业用高压三通的工艺过程,通过FEM模拟总结出高压三通的基本成形规律,并揭示了高压三通多向模锻过程中水平冲头向上翘曲现象及其产生原因,为类似锻件的多向模锻工艺的设计提供了有益的借鉴。In this paper the forming process in the multi-ram forging process of high-pressure tee joint used in power industry and petroleum chemistry industry is introduced. The forming rule of tee joint is summed up by using FEM. The upward warping of the horizontal ram is observed and the reason why this phenomenon happens is discussed. The reliable reference is provided for producing similar forgings by multi-ram forging.
