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.

五金冲压件材料的硬度检测，其主要目的就是确定购入的金属板材退火程度是否适于随后将要进行的冲压件加工，不同种类的冲压件加工工艺，需要不同硬度级别的板材。

stamping material hardness testing, the main is to determine whether the purchase of metal sheet annealing is suitable for subsequent stamping parts processing, different types of stamping processing technology, the need for different hardness levels of the plate.

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.

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.
