【摘要】：设计了一套成形台式电脑机箱主板的多工位级进模,为提高材料利用率,在模具上采用套冲设计,在主产品的设计废料区套冲一个副产品,使材料利用率提高11.6%。在套冲设计上,选取主产品与副产品之间不变形的边作为载体,条料带动主产品和副产品同步运动,较好地解决了主产品与副产品之间的协调问题。整套模具分为6个工步,针对每个工步冲压成形内容较多的问题,在排样设计时合理安排各工步成形内容,使产品在各工步基本达到均匀成形,模具镶件和冲压载荷基本均匀分布。研究表明,当多工位级进模生产产品的废料够多时,可在设计废料区域套冲另外一个工件,可显著提高材料的利用率。
[Abstract]:A set of multi-station progressive die for the main board of the forming desktop computer chassis is designed. In order to improve the material utilization ratio, the sleeve blanking design is adopted on the die, and a by-product is punched in the design waste area of the main product, so that the material utilization ratio is increased by 11.6%. In the design of sleeve blanking, the undeformed edge between the main product and the by-product is selected as the carrier, and the strip material drives the synchronous movement of the main product and the by-product, which solves the coordination problem between the main product and the by-product. The whole die is divided into six steps. In order to solve the problem of more stamping forming content in each step, the forming content of each step is arranged reasonably in the layout design, so that the product can basically reach uniform forming in each step, and the die insert and stamping load are basically evenly distributed. The results show that when there is enough waste in the multi-station progressive die production, another workpiece can be punched in the design waste area, which can significantly improve the utilization rate of the material.
