基于ANSYS的中空阀体多向模锻工艺研究

Study on Multi-direction Die Forging Process for Hollow Valve Body Based on ANSYS

中空阀体在高压环境中工作,其对锻件的力学性能提出了高要求。本文对比了三种中空阀体件模锻工艺对模具载荷的影响。从填充率和锻件应力两方面分析了右端盖模锻工艺对锻造质量的影响。结果表明,右端盖模锻工艺的模具载荷最小,应力分布均匀,锻造质量最好。

As hollow valve bodies work in high pressure environment,it requires high mechanical properties of forgings.The influence of three die forging processes on die load of hollow valve bodies was compared.The influence of die forging process with right end cover on forging quality was analyzed from two aspects of filling rate and forging stress.The results show that the right end cap die forging process has the minimum die load,uniform stress and the best forging quality.
