【摘要】冲压模具在冷冲压加工中，将材料（金属或非金属）加工成零件（或半成品）的一种特殊工艺装备，称为冷冲压模具（俗称冷冲模）。冲压是在室温下，利用安装在压力机上的模具对材料施加压力，使其产生分离或塑性变形，从而获得所需零件的一种压力加工方法。冲压模具是冲压生产必不可少的工艺装备，是技术密集型产品。冲压件的质量、生产效率以及生产成本等，与模具设计和制造有直接关系。
     复合模能在压力机一次行程内，完成落料，冲孔及拉深等数道工序。在完成这些工序的过程中，冲件材料无需进给移动。主要设计内容包括工艺分析，压力计算，刃口尺寸计算，主要零件设计，CAM。

The blanking & piercing compound die of calotte
design & CAM
 
[Abstract] Stamping die-in the cold stamping process, material (metal or non-metallic) processing into parts (or semi-finished products) of a special technique and equipment, known as cold stamping die (commonly known as Die). Stamping - is at room temperature, the use of the installation of the mold in the press to put pressure on the material to produce plastic deformation or separation in order to obtain the necessary parts of a pressure process. Stamping production stamping die is essential to the process equipment, is technology-intensive products. Quality stampings, production efficiency and high production costs and so on, and die design and manufacturing are directly related.
 Compound die in press machine can finsh blanking、piercing、drawing those process in one action. At that time, the pressing don’t need move. The key content include technical analysis, pressure calculation, cutting edge size counting, main sections designing & CAM.
