Abstract：

The deformation characteristics in drawing process of cylinder workpieces into box workpieces were analyzed in detail based on the example from production of high square cup deep-drawing. It was found out that the main reasons of deep drawing defects were uneven transformation of process part in deep drawing process .The structure of drawing die was improved. The results from actual production show that it can effectively reduce the deformation of non-uniform degree by changing the mouth shape and structure of the drawing die，and then make stamping quality to meet technical requirements.
