摘要：

T形不锈钢阀体通常采用板材或棒材切削加工的方式生产，其材料利用率及生产效率低下。针对该问题，提出了一种新的T形不锈钢阀体多轴联动成形工艺，并利用有限元模拟软件Deform-3D，对T形不锈钢阀体的多轴联动成形工艺进行了数值模拟，分析了零件的工艺难点及成形过程中的载荷-时间曲线、等效应力场分布和温度场分布等，最后设计了相应模具并进行了试验验证。研究结果表明：该T形不锈钢阀体多轴联动成形工艺具有可行性，模拟得到的锻件充填饱满，金属流线基本沿锻件轮廓方向，成形过程中的最大载荷为6620 kN，工艺试验得到的锻件的尺寸一致性较好，说明工艺可靠性高，对该类零件的多轴联动成形工艺具有一定的指导意义。

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.
