介绍了一种带切换机构的开花斜楔在汽车顶盖翻边模具中的应用,通过对顶盖的冲压工艺及模具结构的分析,采用一种气动切换机构和开花式的斜楔机构,实现了有天窗和无天窗两种状态顶盖的翻边工艺在同一副模具上进行,阐述了顶盖翻边开花斜楔及切换机构的结构及工作原理,设计的结构具有降低模具工装开发成本、节省冲压车间占用面积和提高工作效率的特点,经过实物生产验证,生产的有天窗及无天窗顶盖的总精度均达到了94%,满足了轿车对外板件的精度要求。
A kind of flow wedge with switch mechanism is introduced in the application of flanging die of automobile roof. Through the stamping process and mold structure analysis of the roof, a pneumatic switching mechanism and a flowering wedge mechanism are introduced to realize A skylight and no skylight two state caps flanging process carried out on the same mold, elaborated the roof flanging flow wedge and switching mechanism structure and working principle, the design of the structure has to reduce the cost of mold tooling development, Saves the area occupied by the stamping shop and improves the work efficiency. After the physical production verification, the total precision of producing the skylight with or without the skylight top cover reaches 94%, which meets the precision requirement of the exterior plate of the car.
