| Objective In this paper, the flanged shaft was studied to achieve products with qualified performance and structure. Methods The structure and process were analyzed, and the specific forming process was finalized as cutting, extruding the shaft part, upsetting the head portion, and anti-extrusion of flange and cavity. Based on this process, a threedimensional model was established for the formation of the flanged shaft, and the forming defects of the flanged shaft were analyzed with the FEM software, and then the process optimization was made to achieve qualified products. Results The results showed that qualified products were obtained after process optimization. Conclusion This process can function as valuable guidance for the production practice. |
