1.1 冲压的概念
什么是冲压？日常生活当中我们常见有许多的冲压制成品，如门窗合
页、拉手、家用电器里的各种五金、汽车和摩托车的金属件、工具农具等等有很多。
但在我们没有进入大学之前对于冲压其实并没有什么概念，也根本不了解与冲压有关的原理。在冲压加工的过程中我们需要用到用于冲压的模具和各种专业的机械设备。
系统的来说，冲压的过程就是，冲压模具的凸模与凹模直接作用于冲压板料上，这时冲压材料接收到模具施加的作用力，从而让冲压材料产生变形或者断裂分离，最后获得所需要的各种成型零件。通常来说，用于冲压加工的一些材料一般都属于板料，且冲压加工跟其他冲压加工的方式方法不同，其他加工成型方法一般都需要加热，但冲压加工的过程特殊些，一般来说就不需要经过加热过程。冲压加工一般只需要由冲压设备提供的冲压力就可以完成加工，所以相对于其它的加工方式，冲压加工与其他加工方法相比比较节省能源。随着冲压模具技术的发展，冲压加工出来的零件能越来越复杂，加工出来的零件精度也越来越高，零件的质量也越来越好。
相比而言，冲压加工的生产效率应该来说还是比较高的，最重要的是操作比较方便，冲压加工容易实现机械化与高度的自动化生产。在加工的过程中，冲压加工不需要冷却，修磨等工序，而且零件从模具中加工出来就可以直接使用。我们常常用于冲压的机械设备的加工效率还很高，且加工速度快，可以在几秒钟内完成一次加工工序，而有些高速冲压设备甚至在不到一秒钟的时间内完成一次加工。
