基于Dynaform的冲压成形工艺因素影响分析

Analysis of the Impact of Stamping and Forming Process Factors Based on Dynaform's

文章结合生产中的实际需要,利用Dynaform软件对某汽车横梁的冲压成形过程进行了数值模拟分析。根据成形零件的质量评价指标,分析压边力、冲压速度、摩擦系数和拉延筋参数变化对冲压件质量产生的影响。在分析过程中较多参数影响导致结果不好,验证开发周期。利用MDO(multidisciplinary design optimization)技术对零件在冲压成形过程中遇到的质量问题,为冲压件工艺设计、模具设计提供设计方案,可以达到有效缩短模具设计及生产调试周期的目的。

Combined with the actual needs in production,this paper uses Dynaform software to numerically simulate and analyze the stamping and forming process of an automobile cross beam.According to the quality evaluation index of the formed parts,the infl uence of the changes of the crimping force,stamping speed,friction coeffi cient and drawbead parameters on the quality of the stamping parts is analyzed.In the analysis process,many parameters aff ect the results and verify the development cycle.The use of MDO�multidisciplinary design optimization�technology to solve the quality problems encountered in the stamping and forming process,to provide design solutions for the process design and mold design of stamping parts,can eff ectively shorten the purpose of mold design and production debugging cycle.
