1.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 8~100mm. The blank material for stamping is usually in the form of sheet or strip, and therefore it is also called sheet metal forming. Some non-metal sheets (such as plywood, mica sheet, asbestos, leather)can also be formed by stamping.
Stamping is widely used in various fields of the metalworking industry, and it plays a crucial role in the industries for manufacturing automobiles, instruments, military parts and household electrical appliances, etc.
The process, equipment and die are the three foundational problems that needed to be studied in stamping.
The characteristics of the sheet metal forming are as follows:
(1) High material utilization
(2) Capacity to produce thin-walled parts of complex shape.
(3) Good interchangeability between stamping parts due to precision in shape and dimension.
(4) Parts with lightweight, high-strength and fine rigidity can be obtained.
(5) High productivity, easy to operate and to realize mechanization and automatization.
1.概述
通过模具使板材产生塑性变形而获得成品零件的一次成形工艺方法叫做冲压。由于冲压通常在冷态下进行，因此也称为冷冲压。只有当板材厚度超过8~100mm时，才采用热冲压。冲压加工的原材料一般为板材或带材，故也称板材冲压。某些非金属板材（如胶木板、云母片、石棉、皮革等）亦可采用冲压成形工艺进行加工。
冲压广泛应用于金属制品各行业中，尤其在汽车、仪表、军工、家用电器等工业中占有极其重要的地位。
冲压成形需研究工艺设备和模具三类基本问题。
板材冲压具有下列特点：
（1）．高的材料利用率。
（2）．可加工薄壁、形状复杂的零件。
（3）．冲压件在形状和尺寸方面的互换性好。
（4）．能获得质量轻而强度高、刚性好的零件。
（5）．生产率高，操作简单，容易实现机械化和自动化。
