汽车前围板拉延成形模面及工艺优化

广威

〔汽车工程职业学院株洲412001〕

摘要:汽车复杂覆盖件的拉延模面决定了冲压件的成形性、外表质量和尺寸精度，是其成

形模具设计的核心和关键，合理设计工艺补充面可有效改善板料变形的均匀性。本文基于

CAD/CAE协同设计思路，对*新款汽车前围板零件拉延成形过程进展数值模拟，通过对模拟

结果的分析，设计合理的拉延成形模面，同时进一步优化成形参数。通过对模拟结果与实际

产品进展了板料厚度比照分析，优化后的模拟结果与实际成形产品的变化趋势一样，模拟精

度可靠。通过成形数值模拟，可预测板料的成形缺陷，对产品构造及冲压成形模面的优化设

计提供了可靠的指导，而且可极大缩短周期，节约本钱。
