在汽车制造工业中,用于生产汽车车身外壳的冷轧薄板是冲压成形的,因此冷轧汽车板性能的优劣主要取决于其冲压成型的性能。因汽车工业是大规模流水线式的生产,冲压成形的成品率之提高具有很大的经济意义,所以目前国内外对如何提高冷轧汽车板的成形性能方法给予了很大的注意。本文准备综述关于提高冷轧汽车板成形性能的研究工作之现状,研究途径及动向。
In the automobile manufacturing industry, the cold-rolled sheet used to produce automobile body shells is stamped and formed. Therefore, the performance of a cold-rolled automobile sheet mainly depends on its stamped and formed properties. Because of the large-scale assembly-line production of automobile industry, the improvement of stamping forming yield is of great economic significance. Therefore, great attention has been paid to how to improve the formability of cold-rolled automotive sheet at home and abroad. This article is ready to summarize the current situation, research approaches and trends on the research of improving the formability of cold-rolled automotive sheet.
