内容简介：

冲压工艺摘 要冲压工艺是塑性加工的基本方法之一。它主要用于加工板料零件，所以有时也叫板料冲压。冲压不仅可以加工金属板料，而且也可以加工非金属板料。冲压加工时，板料在模具的作用下，于其内部产生使之变形的内力。当内力的作用达到一定程度时，板料毛坯或毛坯的某个部位便会产生与内力的作用性质相对应的变形，从而获得一定的形状、尺寸和性能的零件。冲压生产靠模具与设备完成加工过程，所以它的生产率高，而且由于操作简便，也便于实现机械化和自动化。冲压产品的尺寸精度是由模具保证的，所以质量稳定，一般不需再经过机械加工便可使用。冲压加工一般不需要加热毛坯，也不像切割加工那样大量切削材料，所以它不但节能，而且节约材料。冲压产品的表面质量较好，使用的原材料是冶金工厂大量生产的轧制板料或带料，在冲压过程中材料表面不受破坏。 因此，冲压工艺是一种产品质量较好而且成本低的加工工艺。用它生产的产品一般还具有重量轻且刚性好的特点。关键词：加工 冲压 加工环境 机床 模具 塑性加工 The ramming craftAbstract The ramming craft is one of plastic processing essential methods. It mainly uses in processing the sheet components, therefore sometimes is also called the sheet ramming. The ramming not only may the processed metals sheet, moreover may also process the nonmetallic sheet. When ramming processing, the sheet under molds function, produces in its interior causes it distortion the endogenic force. When the endogenic force function achieves the certain extent, the sheet semifinished materials or semifinished materials some spot will then have the distortion which will correspond with the endogenic force function nature, will thus obtain certain shape, the size and the performance components. The ramming production completes the processing process depending on the mold and the equipment, therefore its productivity is high, moreover, because operates easily, is also advantageous realizes the mechanization and the automation. The ramming products size precision is by the mold guarantee, therefore the quality is stable, generally cannot undergo the machine-finishing then to be possible again to use. The ramming processing does not need to heat up the semifinished materials generally, also cuts the processing to be such massive not likely cuts the material, not only therefore it conserves energy, moreover saves the material. The ramming products surface quality is good, use raw material is the Metallurgical plant mass production rolling sheet or the belt material, the material surface is not destroyed in the ramming process. Therefore, the ramming craft is one product quality is good moreover the cost low processing craft. The product which produces with it also has the weight to be light generally, and ri
