1.1冲压的概念、特点及应用

冲压是利用安装在冲压设备（主要是压力机）上的模具对材料施加压力，使其产生分离或塑性变形，从而获得所需零件（俗称冲压或冲压件）的一种压力加工方法。冲压通常是在常温下对材料进行冷变形加工，且主要采用板料来加工成所需零件，所以也叫冷冲压或板料冲压。冲压是材料压力加工或塑性加工的主要方法之一，隶属于材料成型工程术。

冲压所使用的模具称为冲压模具，简称冲模。冲模是将材料（金属或非金属）批量加工成所需冲件的专用工具。冲模在冲压中至关重要，没有符合要求的冲模，批量冲压生产就难以进行；没有先进的冲模，先进的冲压工艺就无法实现。冲压工艺与模具、冲压设备和冲压材料构成冲压加工的三要素，只有它们相互结合才能得出冲压件。

1.1 stamping the concept, characteristics and applications

Stamping mold stamping equipment (mainly press) to put pressure on the material to produce a separation or plastic deformation (commonly known as stamping or stamping) a pressure processing methods to obtain the necessary parts. Stamping cold deformation processing of materials at room temperature, and the main sheet to be processed into the required parts, also called cold stamping or sheet metal stamping. The stamping is one of the main methods of pressure materials processing, plastic processing, part of the material forming the engineering technique.

　　Stamping mold called a stamping die, or die. The die is the batch processing of the material (metal or non-metallic) into the special tools required red. Crucial in stamping die, not to meet the requirements of the die, batch stamping it will be difficult　die without a state-of-the-art, advanced stamping process can not be achieved. The stamping process an
