【摘要】 本文分析了某异形深盒件的多道次普通深拉深与变薄拉深工艺,利用PAMSTAMP 2G软件对零件的成形过程进行了有限元仿真,校验各道次坯料和模具尺寸、形状是否合理,根据模拟预测的成形缺陷,改进了拉深工艺,优化了工艺参数以减少拉深道次。最后设计出相应7道次成形模具,试冲得到合格零件。更多还原

【Abstract】 Multistage deep drawing and ironing processes of an irregular cup is analyzed and finalized in this paper.Finite element simulation in multistage deep drawing process using the software PAMSTAMP 2G was carried out to check out the rationality of the blank and tools’dimensions in each stage.The multistage deep drawing processes of an irregular cup are improved according to the simulation results,and the process parameters are optimized to avoid forming defects such as wrinkling and fracture.A series of multistage deep drawing experiments were conducted,the deformed configuration was compared to the simulation results and the satisfied cups were got.更多还原
