Abstract：

According to empirical formula and theoretical data, ironing progressive die with reducing in diameter and thinning in wall thickness for stainless steel 304 shell was designed. The forming process of continuous ironing was numerically simulated by Deform-3D software. The equivalent stress fields and the regulation of load-stroke curves in the ironing process were revealed. The results of simulation and test show that the maximum stress of the blank focuses on the contacting areas of the die radius and the die work location. The hazardous areas will appear with the decrease of punch radius because the contact stress between the vertical wall and punch radius increases. In order to prevent the last drawing punch from wearing, the product strain, drawing coefficient, thinning and die radius should be reasonably designed. The vertical wall thickness of the drawn parts with reducing in diameter and thinning in wall thickness is homogenizing.
