摘要
按照汽车备轮架加固板零件的冲压成形过程,在PRO/E软件环境下建立了各道冲压工序的三维产品模型,并在此基础上构造了相应工序冲压成形所需的工具型面模型,包括凸模、凹模、压边圈、坯料等;将所建立的工具型面模型导入专用板料冲压仿真分析软件DYNAFORM中,并进行相应的前置处理和工艺条件定义后,建立汽车备轮架加固板零件的一次和二次弯曲仿真模型;最后,对二次弯曲成形后产生的回弹进行了预测,根据预测结果提出采用"过变形"和"侧整形"的措施对回弹进行补偿和控制。仿真结果与实际生产情况吻合良好,证明了在广大中、小型企业中推广普及CAD、CAE技术的可行性与有效性。
According to the stamping process of the gusset plate of spare wheel cartier of automobile, 3D product models of each forming process were established in PRO/E software environment. Based on these models, tool surfaces needed corresponding stamping process were constructed, including punch surfaces, die surfaces, holder binder surfaces and blank etc. After importing the tool surfaces to DYNAFORM software, a specified sheet metal forming simulation software, the first and second bending forming simulation models of part studied were built by corresponding preprocess and process conditions definition. The springback prediction after second bending forming was performed, and based on the prediction results, the excessive deformation and side - rectification were proposed for springback compensation and springback control. The simulation results were agreed very well with case of practical production, this verified the feasibility and validity of popularizing CAD and CAE technology in most medium - sized and small-sized stamping process enterprises.
