Research on Multi-ram Die Forging Process of Bottomless Cylinder Parts with Lug Boss
In order to ensure the reliability and stability of cylinders and hydraulic cylinders during service,forgings must be used for their blanks.According to the structural characteristics of the hollow inside and the convex outside of the bottomless cylinder block with boss,its forging drawing was formulated.By comparing the forming process of blank filling die cavity,forging load,forging strain distribution,forging temperature distribution,and die temperature distribution,the finite element simulation study of four multi-directional die forging schemes was carried out,and the optimal multi-ram die forging scheme was obtained.According to this scheme,the die and test were designed,and the cylinder block forgings with qualified size were formed.
