摘要
The forming process of cone boss is one of typical local process in metal bulk forming. In this paper, it is divided into two characteristic time-interval based modular design method, one is extrusion processing, the other is the process of the die corner overflowed by deformable body. Then the mechanical models of those two are superposed based on slip-line field theory. The resultant mechanical model is used for solution of deforming force and stress field in open-die forging with a cone boss. In this way, the characteristic element model library of metal bulk forming can be enriched, the optimum design of local forming process can also be realized at the same time.
