2.1.1 Summarize about Stamping 冲压概述
(1)Definition 定义
Stamping is the process to exert pressure on the blank so that the blank will undergo plastic transformation or separation to produce workpieces with fixed sizes, shapes and properties. 冲压是通过模具对毛坯施加压力,使之产生塑性变形或分离,从而获得具有一定尺寸、形状和性能的工件的加工方法。
(2)Type of Stamping Process 冲压工艺的类型
The stamping process is divided into separating and forming.冲压可分为分离工序和成形工序。
(3)Common Stamping Process 常见的冲压工序

(1)Blanking Dies 冲裁模
The blanking dies refer to dies which exert blanking forces on blanks so as to realize processes such as separating, blanking, piercing, trimming, parting, etc.as required.So blanking dies are divided into blanking die, piercing die, trimming die, parting die, cutting-off die, etc. 对毛坯材料施加冲裁力,从而使毛坯材料按要求实现分离、落料、冲孔、切边、剖切等工序使用的模具都属于冲裁模。因此,冲裁模分为落料模、冲孔模、切边模、剖切模、切断模等。

(4)Continuation Die 连续模
In one journey of the press, the continuation die completes a series of successive stamping processes in the feed-in direction of the strip in proper order and the strip gets formed successively from the first station to the final station.So each motion of the press produces a whole completed workpiece or a whole process piece. 在压力机的一次行程中,连续模在依次分布于条料送进方向的几个工序上完成一系列冲压工序,条料从第一工位到最后工位相继成形,因此压力机每动作一次即获得一个完整的工件或工序件。
