摘　　要：通过对天线外壳的工艺分析及计算,提出了落料、冲孔、拉深成形工艺。为了增加内外切开凸模的使用寿命,简化了这种结构形状及尺寸,并用拉料形式代替送料方式,可防止冲底孔凸模易于损坏。经多年来生产验证,该模具结构清晰、可靠,加工质量好,生产效率高。Referring to a series of analysis and calculation,the forming process of antenna shell is designed to have 3 steps,blanking,punching and drawing.In order to increase the life of the inner and outside shearing punch,the shape and dimensions of the die structure is simplified.In this structure,the material feeding method is drawing instead of feeding,which could prevent the damage of bottom-hole punch.Applied in production for many years,this die structure is not only clear,reliable and of high efficiency but also its product has good quality.This proposed method could be considered as reference to die design of a similar part.
