摘要
目的结合高强度钢板纵梁前段工艺难点及特征,提出对该零件回弹进行预测和控制的方法。方法采用经验设计和CAE分析技术相结合的方法,对零件全工序成形及回弹过程进行了仿真模拟分析,同时对零件产生回弹的原因进行了深入分析,提出了回弹问题的解决方案。结果通过采取有效措施对回弹进行控制,成功解决了零件质量问题,回弹控制在了1 mm之内,平均合格率达到了91.8%,满足了装车要求。结论全工序CAE分析可有效预测高强度钢板梁类零件的成形质量缺陷和回弹状态,并指导工艺设计和模具型面补偿,合理的梁类扭曲回弹解决方案为类似零件模具的开发提供了参考。
The aim of this study was to propose a method for prediction and control the springback base on the technical difficulties and features of the front longitudinal beam. Using the method of design experience and CAE technology,the numerical simulation of forming process and springback for the front longitudinal beam was studied. The springback causes were analyzed in details and the solution were put forward. The quality of the products is guaranteed through the effective technical measures. Springback was controlled within 1 mm,and the average qualified rate reached 91. 8%. Through the whole process of CAE analysis,the quality defect and springback condition can be effectively predicted. It also can guide the technological design and die surface compensation,which provides a reference for the process plan and springback solution of similar part.
