冲压变形外文文献

1、附录 1 外文译文 第八章 冲压变形 冲压变形工艺可完成多种工序，其基本工序可分为分离工序和变形工序两大类。 分离工序是使坯料的一部分与另一部分相互分离的工艺方法，主要有落料、冲孔、切边、剖切、修整等。其中有以冲孔、落料应用最广。变形工序是使坯料的一部分相对另一部分产生位移而不破裂的工艺方法，主要有拉深、弯曲、局部成形、胀形、翻边、缩径、校形、旋压等。 从本质上看，冲压成形就是毛坯的变形区在外力的作用下产生相应的塑性变形，所以变形区的应力状态和变形性质是决定冲压成形性质的基本因素。因此，根据变形区应力状。

3、Characteristics and Sheet Metal Forming1 The article overview Stamping is a kind of plastic forming process in which a part is produced by means of the plastic forming the material under the action of a die. Stamping is usually carried out under cold state, so it is also called stamping. Heat stamping is used only when the blank thickness is greater than 8100mm. The blank material for stamping is usually in the form of sheet or strip, and therefore it is also called sheet metal forming. Some n。
