| Abstract: | The paper aims to research multi-direction precision forming technology of double flanges Tri-Valve set body. Based on structural characteristics of double flanges Tri-Valve set body, a multi-direction precision forming technology was proposed to have numerical simulation through Deform-3D software of finite element analysis. In this process, the load-stroke curve, the metal flow law, etc. were analyzed. The process experiment was also carried out. The multi-direction precision forming technology could form a double flanges Tri-Valve Set body at allowed stress. Forge pieces obtained in the process experiment were filled fully. Data obtained were basically in line with the simulation result. The proposed multi-direction precision forming technology for double flanges Tri-Valve set body is practical. It has guiding significances for the actual production and other similar parts. |
