以某车型前防撞横梁内板为研究对象,采用有限元方法分析了该零件冲压成形过程中的主要缺陷。针对影响其成形的主要因素(压边力、摩擦系数、模具间隙和冲压速度),设计了正交试验。基于综合平衡法,进行了工艺优化。制定出零件不破裂和起皱时,回弹量最小、厚度减薄小的最优工艺参数。这对该零件的实际冲压工艺设计具有重要的工程意义。 Taking a front bumper beam of a car as the research object, finite element method was used to analyze the main defects in the stamping process. Orthogonal experiments were designed according to the main factors affecting the forming process (blank holder force, friction coefficient, die gap and punching speed). Based on the integrated balance method, process optimization was carried out. Developed the parts do not rupture and wrinkling, the minimum amount of rebound, the thickness of the thinning of the optimal process parameters. This has important engineering significance for the actual stamping process design of the part.
