| 目的 研究汽车翼子板前门区域尺寸匹配控制方法，提高前门区域尺寸匹配平整度。方法 从拉延补充工艺面造型、直翻工艺、侧翻角度3个方面来优化成形工艺，依据回弹扫描结果进行局部回弹补偿，建立翼子板的前门区域尺寸匹配控制方法。结果 大量同类翼子板应用测试结果表明，在拉延补充工艺面造型、直翻工艺、侧翻角度3个方面的工艺优化基础上，进行局部区域的回弹补偿，可以使翼子板的前门区域匹配精度较好地达到评估标准。结论 实验验证这套方案适合多数翼子板零件，可以有效保证翼子板与前门匹配处平整度。 |
| 英文摘要: |
| The paper aims to research the dimension controlling method for door-side area of automobile fender to improve dimension match flatness in front door-side area. Forming processes including drawing addendum geometry, flanging process and cam flanging angle were optimized, and springback compensation was conducted according to results of springback scanning. Thus, a dimension controlling method of automobile fender for matching with front door was developed. In plenty of tests on similar automobile fenders, the quality of automobile fender dimension match flatness in front door-side area met the evaluation criteria based on the forming process optimization in drawing addendum, flanging process and cam flanging angle and springback compensation in partial area. The method is suitable for parts of most fenders and can improve dimension match flatness of fender and front door efficiently. |
