5、gnAbstractIn this design,my topic is automobile lampshade stamping’s industrial analysis and mold design. Through the analysis we can found that chimney parts is no flange cylindrical parts.This part structure is complex and it needs more working procedure to complete.The main shape is compl
6、eted by blanking drawing, the shrink shape completed by neckling mould is also needed. In the design process, in view of this product, we must first clear route design, determine the design scheme and design the mould structure.We must coduct size of the structure analysis, using of CAD dra
7、wing ,then determine the size and choose the best process.After that, we must finish blanking deep drawing process and reducing process and dimension calculation.Next is the calculation of burst pressure. It can help us to select suitable stamping
