【摘要】沖壓模具在冷沖壓加工中，將材料（金屬或非金屬）加工成零件（或半成品）的一種特殊工藝裝備，稱為冷沖壓模具（俗稱冷沖模）。沖壓是在室溫下，利用安裝在壓力機上的模具對材料施加壓力，使其產生分離或塑性變形，從而獲得所需零件的一種壓力加工方法。沖壓模具是沖壓生產必不可少的工藝裝備，是技術密集型產品。沖壓件的質量、生產效率以及生產成本等，與模具設計和制造有直接關系。
     復合模能在壓力機一次行程內，完成落料，沖孔及拉深等數道工序。在完成這些工序的過程中，沖件材料無需進給移動。主要設計內容包括工藝分析，壓力計算，刃口尺寸計算，主要零件設計，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.
