摘　　要：在级进模设计过程中,压力中心位置的确定是非常重要的设计内容,应尽可能与机床滑块中心保持一致。以某产品为研究对象,制定了其级进模冲压工序和排样图。建立了该产品的连续成形有限元模型,模拟得到了各个工位的冲压力变化曲线,运用解析法和有限元模拟方法求得压力中心,进行比较发现两者的偏移量在允许的最大偏移范围内。研究结果为实际生产中级进模压力中心位置的确定提供了技术指导。The location of pressure center is important in progressive die design, which should be cortsistent with the center of press slide at utmost. The stamping process and stamping layout were determined based on a specific product. The continuous forming finite element model of the product was established, and the curve of stamping force for each step was got, and the location of pressure center was obtained by the analytic method and finite element simulation. The offset between them is in the range of maximum migration. It provides a technical guidance for the determination of the location of pressure center for progressive die in practical production.
