Abstract：

T-shaped stainless steel valve body is usually produced by cutting plate or bar, which has low material utilization and production efficiency. Therefore, a new multi-axis linkage forming process of T-shaped stainless steel valve body was proposed, and the multi-axis linkage forming process of T-shaped stainless steel valve body was numerically simulated by finite element simulation software Deform-3D. Then, the process difficulties of parts and the load-time curve, equivalent stress field distribution and temperature field distribution in the forming process were analyzed. Finally, the corresponding die was designed and verified by experiment. The research results show that the proposed multi-axis linkage forming process of T-shaped stainless steel valve body is feasible. The simulated forgings are fully filled, and the metal streamline is basically along the contour of forgings, the maximum load in forming process is 6620 kN. The dimensional consistency of forgings obtained from the process test is good, which shows that the process reliability is high and has certain guiding significance for the multi-axis linkage forming process of this kind of parts.
