通过有限元Deform-3D对大型厚壁封头整体锻造过程进行模拟,得出了金属在成形过程中流动规律和成形力。结果表明,在万吨级水压机上采用逐步循环等量下压法能够生产出满足尺寸要求的产品。 Through the finite element Deform-3D to simulate the whole forging process of large-thickness thick-walled head, the flow rule and forming force of the metal in the forming process are obtained. The results show that in the 10,000-ton hydraulic press with a step-by-step equal-pressure method can produce products to meet the size requirements.
