摘　　要：现代大型客运车辆都安装有空气调节器,而空调中都要安装风机,为了通风,风机固定在薄板大直径翻边孔的底板零件上。大型车辆的年产量不多,在对该零件的加工方案进行经济分析的基础上,根据滚剪、滚压加工基本原理,设计了一台结构简单、功效合理、费用少的专用设备。实际应用表明,该设备解决了小批量生产薄板大直径翻边孔的加工问题,这种简便可行的方法,对批量不大的薄板大直径翻边孔加工具有良好的推广前景。In the modern large-scale passenger train vehicles, generally all is loaded with the air conditioning regulator, and in the air conditioning all must install the air blower. In order to ventilate, the fixed air blower has together the sheetmetal large-diameter flanging-hole part. In view of the large-scale vehicles annual output, after economic analysis, according to the principle of rooling-shear, rool-performing, a special equipment with simple structure, reasonable effectiveness and few expense was designed. Practical application shows that the equipment solves the processing problem in small-batch-production of sheetmetal with large-diameter flanging-hole. The easy and feasible method has good prospect for promotion in small-batch-production of sheet- metal with large-diameter flanging-hole.
