摘要: The cold semi-precision forging of a multi-row sprocket was investigated using upper-bound (UB) and finite element methods combined with experiments. Based on the design new tooth profile for sprocket, process kinematically admissible velocity field filling die cavity were proposed. Using UB method, fields billet in forming divided theoretically calculated. simulated FEM package Deform-3D V6.1 to obtain distributions effective stress cavity. Similar results, experiment 5052 aluminum alloy successfully performed. By comparing calculated (UB method), experimental load-stroke curves, results basically accordance results. study provides theoretical foundation development precision sprockets.
