Abstract：

Stamping process of an automobile roof panel was introduced based on the analysis of its characteristics. Therefore the side sizing die of the skylight in automobile roof panel was designed. Based on the requirements of actual production, three sets of side sizing wedges were designed in the flanging area of the skylight in the fourth process. Both the punch and die of the side sizing should be designed on the lower die. The roof panels with or without skylight could be formed. The application of two kinds of two-way movement wedges structure in the side sizing die for the skylight of the roof panel were discussed in particular. Two groups of tram wedges were adopted on the left of the skylight and close to the center region of the lower die. They were driven by two cam drivers respectively, which resulted in the flexibility of adjustment and the stability of the wedge structure. The two-way movement wedge was adopted in the front and rear side of the skylight because of compact structure and space saving. Through the flexible use of the two-way movement wedges, the results show that the die structure is reliable and feasible, which is convenient for manufacturing and adjustment, and it can also reduce the cost, guarantee the quality and improve the efficiency.
