Abstract：
|
|
The front cover of digital camera is a precise partApproximately, it can be considered as an irregular box shaped pieceIts shape is complex and its surface finish is highIn view of its process difficulty and characteristics, and combining experience design with numerical simulation, the finite element model is built, and its working procedures are analyzed one by one, which include blanking piercing and forming and trimmingThereby, the reasonable process is determined;The spread shape is optimized while analyzes the blanking piercing processWhen analyzing the forming process, the mould clearance——the most important process parameter, is determined and optimized;At the same time, the design method and structure feature of the mould are introducedEspecially, the side punch mould is illustrated in detail
