摘要：

以某汽车全景天窗顶盖为研究对象，通过对全景天窗顶盖产品的工艺性和模具结构布局的成立性进行分析，合理规划各工序的工艺内容，实现了全景天窗顶盖两侧流水槽修边与侧整形的工序集成、后侧尾翼安装面修边与侧整形的工序集成以及天窗开口部修边与翻边的工序集成，从而将全景天窗顶盖冲压模具工序从4工序缩短至3工序。重点阐述了实现全景天窗顶盖冲压模具3工序化所应用的两种凸模扩张斜楔机构。在全景天窗顶盖两侧流水槽设计了一种水平推拉式凸模扩张斜楔机构，在全景天窗顶盖后侧尾翼安装面设计了一种竖直推拉式凸模扩张斜楔机构。研究表明，两种不同类型的斜楔机构的联合应用，可以使全景天窗顶盖在同一工序完成更多的工艺内容，实现了三面负角结构的修边与侧整形的同步化，缩短了冲压模具工序，降低了冲压模具成本，提高了零件的生产效率。

For an automobile panorama sunroof panel, through analyzing the manufacturability of the panorama sunroof panel product and the practicability of the die structure layout, the process content of each process was rationally planned, and the process integration of trimming and side restriking for gutter channel on both sides of the panorama sunroof panel, the process integration of trimming and side restriking for rear wing mounting surface on back side of the panorama sunroof panel, as well as the process integration of trimming and flanging for sunroof opening were realized. Therefore, the stamping die process for the panorama sunroof panel was shortened from four-process to three-process. Then, the two kinds of punch expansion wedge mechanism used to realize the three-process stamping die for the panorama sunroof panel were mainly expounded. Furthermore, a horizontal push-pull punch expansion wedge mechanism was designed in the gutter channel on the both sides of the panorama sunroof panel, and a vertical push-pull punch expansion wedge mechanism was designed on the rear wing mounting surface on back side of the panorama sunroof panel. The research shows that the combined application for two different types of wedge mechanisms can enable the panorama sunroof panel to complete more process content in the same process, realize the synchronization of trimming and side restriking for the three-sided negative angle structure, shorten the stamping die process, reduce the cost of stamping dies and improve the production efficiency of parts.
