| Abstract: | This paper uses finite element method to calculate and analyze the stress of nodes in hot extrusion dies. It is indicated that there is an obvious stress concentration in the body of dies where it is very easy to form crackles. By the optimal design to the structural measurements of hot extrusion dies,the maximum stress in the body of improved dies is decreased by 32.2%,the lifespan is therefore prolonged. |
