板料冲压是利用模具,借助冲床的冲击力使板料产生分离或变形,获得所需形状和尺寸的制件的加工方法。这种方法通常是在冷态下进行的,所以又称为冷冲压。用于冲压加工的材料应具有较高的塑性。常用的有低碳钢、铜、铝及其合金,此外非金属板料也常用于冲压加工,如胶木、云母、石棉板和皮革等。冲压件尺寸精确,表面光洁,重量轻,刚性好,一般不再进行机械加 Sheet metal stamping is the use of molds, with the impact of the punch plate separation or deformation, to obtain the desired shape and size of the workpiece processing methods. This method is usually carried out in cold state, so it is also called cold stamping. Materials used for stamping should have higher plasticity. Commonly used in low carbon steel, copper, aluminum and its alloys, in addition to non-metallic sheet metal is also commonly used in stamping processing, such as bakelite, mica, asbestos and leather and so on. Stamping size accurate, smooth surface, light weight, good rigidity, the general is no longer mechanical plus
