| Abstract: | Aiming at the cool-extrusion process of a cylinder part,suitable technology parameters and the tool sizes have been determined. Combining with the numerical simulation by FEM method,numerical calculation of the process has been carried out. Based on it,the reason of the deformation defects-necking has been analyzed,and the technology scheme has been optimized,which guarantees the success of the technology. |
