提出了转向节预成形优化设计新工艺。针对某转向节半封闭式锻造成形过程,利用有限元法进行了数值模拟分析,研究了坯料四个关键部位尺寸对成形质量的影响;通过模拟转向节成形过程,预测成形缺陷,确定了预成形优化工艺参数。结果表明,通过预成形优化设计,成功解决了成形过程中的缺陷,有效地降低了最大成形载荷,提高了模具寿命,在很大程度上减少了试模时间和生产成本,提高了生产效率。
Proposed knuckle preforming optimization design of new technology. Aiming at semi-closed forging process of a knuckle, the finite element method was used to carry out the numerical simulation analysis. The influence of the four key parts’ size on the forming quality was studied. By modeling the knuckle forming process and predicting the forming defects, the preforming Optimize process parameters. The results showed that the preforming optimization design successfully solved the defects in the forming process, effectively reduced the maximum forming load, increased the service life of the die, greatly reduced the test time and production cost, and improved the production efficiency.
