On the platform of nonlinear finite element software Dynaform, for the first drawing process of 1725 printed aluminum cover, the numerical simulation of stamping and deep drawing process under different drawing speeds was conducted respectively under the condition of keeping other process parameters unchanged. The results show that the drawing speed range for the stamping and deep drawing of the first time for 1725 printed aluminum cover without crack is 2000-6000 mm·s-1 (Excluding 2000 and 6000 mm·s-1), and the variation rules of the maximum wall thickness, the minimum wall thickness, the difference between the maximum wall thickness and the minimum wall thickness, as well as the parameters such as the thickening rate, the thinning rate and the thickness variance of vertical wall were studied. The results show that the reasonable speed range of the stamping and deep drawing for 1725 printed aluminum cover of the first time is 4000-5500 mm·s-1, in which 4000 mm·s-1 is the more ideal drawing speed. Finally, the production test shows that the qualified products with ideal quality can be produced with the drawing speed of 4000 mm·s-1.
