摘　　要：分析了LED灯罩零件结构工艺性,制定了合理的工艺方案,详述了传递模的设计、结构及工作原理。该传递模具采用拉深、反拉深、压內形、切边、压毛边、冲孔、二次拉深、向下压卷、三次缩口等十个工序,有效解决了拉深开裂、缩口起皱等问题。实践证明:该传递模具结构合理,工作稳定,生产效率高,产品精度及品质满足要求。This paper analyzes the structural technology of LED lampshade, formulates a reasonable process scheme,and details the design, structure and working principle of the transfer die. Ten processes, such as deep drawing,reverse drawing, internal shape, edge cutting, edge pressing, punching, secondary drawing, downward coiling, and third shrinkage, are adopted to effectively solve the problems of deep drawing cracking and wrinkling. The practice shows that the transfer die has the advantages of reasonable structure, stable work, high production efficiency, high product precision and high quality.

关 键 词：传递模 拉深 反拉深 缩口
