摘　　要：为保证汽车车门外水切的尺寸精度,减少挤出生产缺陷并保证水切安装后的稳定性,芯金的形状及成形精度尤为重要。对一类不对称芯金断面辊压成形工艺进行研究,使用计算机辅助工程(CAE)对断面结构进行仿真分析,在确保不影响性能的情况下,对芯金结构型式和现有辊压工装结构进行优化,解决了一类非对称断面产品生产中的窜料缺陷和碾料问题,并以此为依据完成了多套辊压工装开发,有效提高了汽车零部件的生产品质。In order to ensure the dimensional accuracy of the outer belt weather-strip,reduce the extrusion production defects and ensure the stability of the outer belt weather-strip installation on the door,the shape of the metal insert and the forming accuracy are particularly important.In this paper,the roll forming process of a kind of asymmetric metal insert section is studied,the cross-section structure is simulated and analyzed by CAE method,and the metal insert structure is optimized and the structure of the existing roll-forming tooling is optimized without affecting the performance,thus solving the defects of material crossing and grinding in the production of a kind of asymmetric section products.Based on this,multiple sets of roll-forming tooling are developed,which effectively improves the production quality of auto parts.
