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。

简单来说钣金件是金属薄板壳体，冲压件就是用拉伸机或冲床等加工的工件1，钣金件在折弯过程中厚度不会有变化，但在汽

车钣金壳体中应为敲击等原因，一部分表面会有一定变化。冲压厂是不能确定落料尺寸的，应该是在定做模具时由模具厂试定出来的。

In a simple way, the sheet metal part is a metal sheet shell, and the stamping part is 1 of the workpiece, which is processed by a drawing machine or a punch press. The thickness of the sheet metal parts will not change during the bending process, but in the steam.

The surface of the automobile shell should be knocked and so on. Part of the surface will change. The stamping plant is unable to determine the blanking size. It should be determined by the mold factory when making the mould.

清除冲压机床滑块底面、工作台面（或垫板平面）以及模具的上、下模座平面内的任何杂物或***。手工扳动冲压机床飞轮（或操纵点动按钮），调整上滑块到上死点位置，并转动调节螺杆，将连杆长度调到***短（即闭合高度大）。

Remove any material or foreign object on the bottom of the stamping machine slide, working table (or pad plane), and the upper and lower die base of the mold. Manually pull the stamping machine flywheel (or point moving button), adjust the upper slider to the upper dead point, and rotate the adjusting screw, the length of the connecting rod to the shortest (i. e. the maximum height of the closed height).
