某型号导弹包装箱切角模具的设计

Design of the blanking-angle die for a missile packing box

论证了某型号导弹包装箱体和箱盖零件下料工艺方案,介绍了拉深展开料的计算过程、切四角模具的结构设计思想和特点。使用同一套切角模具能在费用很低的情况下完成箱体和箱盖的下料,提高了制件质量和生产效率,有效地控制了后续拉深工序的废品率,达到降低成本的目的。

In this paper,the technical planning on blank -cut ting for the sheet of a missile packin g box was discussed,the blank dimension calculation pro cess,the structure and characteristics o f the blanking -angle die were introduced.The blanking sheet of the box and cover drawing parts can be finished with the same die.This die makes the production efficiency much higher and the quality of next drawing process much better with a lower cost.
