介绍了某汽车左右车门外板支撑板的工艺及模具结构设计,通过优化工艺及模具结构,将左右车门外板支撑板同模生产,即在同一副模具中完成拉延、修边冲孔、剖切等冲压工序。重点讲述了左右车门外板支撑板共模拉延的工艺及其多工位模具的结构及工作原理。生产实际证明,该模具有效地降低了模具开发成本;将原来的六套模具整合成一套模具,降低了机床的冲次费用,减少了冲压操作工人的数量,提高生产节拍和生产效率,节省了冲压车间模具的存放空间;材料利用率较预估的单件拉延提升了5.66%。将此技术应用于同类产品会大大降低整车白车身的开发费用。
The process and mold structure design of the support plate of the left and right door outer panels of a car are introduced. By optimizing the process and mold structure, the support plates of the left and right door outer panels are produced in the same mode, that is, drawing, trimming and punching in the same mold, Cutting and other stamping process. Focus on the left and right door outer panel common-mode drawing process and its multi-station mold structure and working principle. Production proved that the mold effectively reduces the cost of mold development; the original six sets of molds integrated into a set of molds, reducing the impact of the machine tool costs, reducing the number of stamping workers and improve the production cycle and production efficiency, saving Stamping workshop mold storage space; material utilization than the estimated single piece drawing increased 5.66%. The application of this technology to similar products will greatly reduce the development cost of the vehicle bodywork.
