冲压件与铸件的区别:具有薄、匀、轻、强的特点冲压可制出其他方法难于制造的带有加强筋、肋、起伏或翻边的工件,以提高其刚性。由于采用精密模具,工件精度可达微米级,且重复精度高、规格一致,可以冲压出孔窝、凸台等。

冷冲压件一般不再经切削加工,或仅需要少量的切削加工。热冲压件精度和表面状态低于冷冲压件,但仍优于铸件、锻件,切削加工量少。

冲压主要是按工艺分类,可分为分离工序和成形工序两大类。

分离工序也称冲裁,其目的是使冲压件沿一定轮廓线从板料上分离,同时保证分离断面的质量要求。 冲压是高效的生产方法,采用复合模,尤其是多工位级进模,可在一台压力机上完成多道冲压工序,实现由带料开卷、矫平、冲裁到成形、精整的全自动生产。

生产效率高,劳动条件好,生产成本低,一般每分钟可生产数百件。成形工序的目的是使板料在不破坯的条件下发生塑性变形,制成所需形状和尺寸的工件。在实际生产中,常常是多种工序综合应用于一个工件。冲裁、弯曲、剪切、拉深、胀形、旋压、矫正是几种主要的冲压工艺。
