合理的模具设计。在级进模中,下料顺序的安排有可能影响到冲压件成形的精度。针对冲压件细小部位的下料，一般先安排较大面积之冲切下料，再安排较小面积的冲切下料，以减轻冲裁力对冲压件成形的影响。

Reasonable mold design. In progressive die, the order of blanking sequence may affect the accuracy of stamping forming. In order to reduce the impact of punching parts, the punching and cutting blanking of ***all area is arranged in the light of the blanking of the ***all parts of the stamping parts.

五金冲压件与铸件、锻件相比，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。秦皇岛五金冲压件由于采用精密模具，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。

薄板：锯削时尽可能从宽面锯下去，若必须从窄面锯下时，可用两块木垫夹持，连木块一起锯下，也可把薄板直接夹在虎钳上，用手锯作横向斜推锯，使锯齿与薄板料接触的齿数增加，避免锯齿崩裂。

Thin plate: sawing as far as as wide as when sawing. If must be sawed from narrow surface, it can be held by two wooden blocks and sawed together with wooden blocks. The sheet can be clipped directly to the vise, and a hand saw is used as a transverse oblique saw to increase the number of teeth contacted with the sheet material and ***oid the crack of the saw teeth.
