Mould pressing production is a kind of advanced mechanical processing manufacturing technology of the parts stamping processing production has high quality and use good performance characteristics, so widely applied in production . Progressive die is a complex, precision stamping mould. It has the high efficiency, high precision and high life superiority, applicable to all kinds of stamping industry automation production. This design is a punch down to the materials punching die design. The parts of stamping process analysis, the determination of reasonable stamping process program, selected stamping progressive die. The progressive die design including the key process calculation, the main parts of the die design and overall design, the design USES guide material plate material sent into the article control direction, the side blade and side blade block piece of system of material sent from the article progress, diagonal guide pin orientation, unloading with fixed unloader device. Punching blanking simultaneously. Key words：Stamping mould; Progressive die; Mold design 目 录 1前言 1 1.1我国冲压模具业发展现状 1 1.2我国冲压模具制造技术发展趋势 2 1.3冲压模具技术国内外发展趋势 4 2冲孔落料件冲压模具设计 6 2.1冲压件工艺性分析 6 2.2冲压工艺方案的确定 7 2.3主要设计计算 9 2.3.1排样方式的确定以及计算 9 2
