The invention discloses a process optimization method for improving a wheel opening side wall indentation of a wheel fender after drawing, and convex hull models are uniformly added on a drawing wheel opening side wall process supplement surface to control a wheel fender wheel opening drawing side wall forming process. Convex hull models are uniformly added on a drawing wheel opening side wall process supplementary surface, the draft angle and the R angle of a convex hull plane are changed, the distance between convex hulls is controlled, the contact point of a plate and a convex-concave die when a wheel opening side wall concave die fillet and a wheel opening side wall are formed is changed in the drawing process, and the contact process of a side wall draft surface is changed. A plate is not subjected to force in a single direction in the forming process, after being drawn to the bottom, the plate is piled through the convex-concave R angle of the convex hull, the rigidity of a workpiece of the side wall of
