| Abstract: | The forming process of flange forming by upsetting extruding tube is discussed in detail in this paper. The FEM analysis has been used to analyze the influence of lubrication condition on the metal flow of the forming process and the cause of defection. Then the relational curves between flange width and ultimate friction factor for two kinds of inner radius and three kinds of tube thickness have been given. The subsequent experiment verification has resulted in a conclusion that numerical simulation results well agree with experimental results. |
