根据耳环安装零件的结构特点及实际生产的技术要求，进行多工位级进模排样设计。由于耳环安装零件结构不对称，故其排样设计采用对称排结构，导正孔设计在双排中心线处，保证板料在移动过程中的平稳，从而确保板料冲裁、折弯时的强度以及确保送料精度，同时，采用导正销确定步距。该耳环安装零件多工位级进模采用顺装结构，使得工件与废料自然分离，有利于减少人工成本。同时，由于耳环安装零件的精度要求较高，故进行了多个空工位的设计，以确保其成形精度。结果表明，耳环安装零件多工位级进模能满足产品生产要求。该模具的材料利用率高达63.3%，极大地节省了材料。

According to the structural characteristics of earring installation parts and the technical requirements of actual production, the multi-station progressive die layout design was carried out. Due to the asymmetrical structure of earring installation parts, the layout design adopted a symmetric row structure. The guide hole was designed on the center line of the double rows to ensure the smoothness of sheet during the movement, the strength of blanking and bending for sheet, as well as the feeding accuracy. At the same time,the step distance was determined by using the guiding pin. The multi-station progressive die of earring installation part adopted a splicing structure, which made the workpiece and the waste naturally separated to reduce labor costs. At the same time, due to the high precision requirements of earring installation parts, a number of empty stations were designed to ensure the forming accuracy. The results show that the multi-station progressive die of earring installation parts can meet the production requirements of products. The material utilization rate of die is as high as 63.3%, which greatly saves the material.
