The present invention relates to a method for controlling the surface quality of the stretching forming coating of high-strength aluminum alloy, and comprises the steps that the stretching formed roughcast is correctly arranged on the stretching forming lathe and the work station; stable and middle stretching forming speed is adopted for the operation; the deformation volume of the pre-stretching forming is controlled within the range of 1 percent to 1.5 percent; the pre-stretching formed roughcast is undertaken the solid-melting processing, and is aged for 20 to 25 hours at the room temperature, and then is performed the second (final) stretching forming. Through the correct installation of the material on the work station and the device, the material stays at the uniform plastic deformation status during the stretching forming process, so that the appearance of the coating is obtained with the minimum extension rate; through the control of the pre-stretching forming deformation volume, the problems such as the large plastic deformation and large material crystal grain are prevented during the solid-melting processing heating process. The problems that the appearance accuracy is poor for large crystal grain appears on the surface or for the less stretching deformation volume are resolved during the stretching forming of the high-strength aluminum alloy coating.
