钣金件冲模设计---外文翻译.doc

A brief introduction on the sheet metal blanking and piercing dies is presented in Chapter 21. In practice component is produced essentially by combinations of blanking, piercing, bending or drawing operations in a certain order. The dies discussed previously are involved in carrying out only a single operation. But the most practice dies have to do more than one operation for making a finished component. In this chapter, the details of the design of such dies are discussed.

在21章简明扼要的介绍了落料模和冲孔模。实际组成成份的本质是在特定工序中落料模、冲孔模、弯曲模或绘图操作的组和。以前的模具讨论只涉及到执行单一的操作。但是为了完成结构,许多实际的模具不得不做更多的操作,在这一章,将讨论这种模具的设计细节。
22.1模具类型
钣件模具可以广泛的分为三类：连续冲模、复合模，组合模。
连续冲模
在压力机压力下,连续冲模在单冲程下同时进行两个或更多的操作。因此完整的冲裁是获得每一单冲程的操作,执行单冲程中的每一步操作叫做工序。毛坯条从这个工序移动到另一个工序并经受特殊的操作。当条料最终完成最后一道工序,一个完整的结构已经完成。
