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。
日常模具生产中，应注意维护冲切凸、凹模刃口的锋利度。当冲切刃口磨损时，材料所受拉应力将增大，从而冲压件产生翻料、扭曲的趋向加大。
In daily mold production, attention should be paid to sharpness of punching and conc***e die edges. When the cutting edge is worn, the tensile stress of the material will increase, and the stamping and bending will increase.
五金冲压模具的安装是否正确合理，不仅影响五金冲压件的产品质量和精度，还会影响模具的工作寿命及生产安全。并且熟练掌握冲压模具的安装也是每个冲压工应该掌握的技巧。
Whether the installation of the metal stamping die is correct and reasonable, not only affects the quality and precision of the metal stamping parts, but also affects the working life and production safety of the die. And skilled in stamping die installation is also a skill that every stamping worker should master.
将闭合的模具放置于雎力机工作台或垫板上适当位置，如果使用气垫，先要放好顶杆，并标记好模具的摆放位置。
手动扳动冲压机床飞轮（或操纵点动按钮），使机床上滑块下行并停于下死点位置。
Place the closed mould on the bench or pad of the mandrel machine. If the air cushion is used, the ejector pin should be placed first and the placement of the mould should be marked.
Manually pull the flywheel of the stamping machine (or the moving button), so that the slider on the machine tool will be downhill and stop at the bottom dead center.
