摘要
在行李箱盖内板成形过程中,制件内型面支撑筋两侧材料流动较复杂,制件表面容易起皱,针对此问题,分析制件起皱的原因,并对原模具结构和冲压工艺提出了改进方案及整改措施。
In the process of forming a trunk lid board, the materials flow at the area of parts stiffener sides was complicated, and the parts appearance was prone to wrinkling. Aiming at the problems, the reason for part wrinkling was analyzed, and some improvement schemes and corrective measures were put forward on the basis of original die structure and stamping process.
