The invention discloses rolling cutters of flour-wrapper forming machine of a sesame seed cake. The machine comprises rolling cutters and a pipe for fixing the rolling cutters. Three rolling cutters are uniformly arranged on the outer surface of the pipe for fixing the rolling cutters. Each rolling cutter is composed of two long arc plates and two short arc plates, which are arranged at intervals through welding, and the inner arc of the rolling cutter is directly welded on the outer surface of the pipe for fixing the rolling cutters. The invention also discloses a processing method of the rolling cutters of the flour-wrapper forming machine of a sesame seed cake. The processing method comprises decomposing a projection drawing by a graph decomposition method; drawing the blanking green body of the long arc plate and the blanking green body of the short arc plate, blanking and welding; cutting an inner arc line and an outer arc line on wire-cut equipment; and welding one cut rolling cutter on the pipe for fixing the rolling cutters. The rolling cutters processed in the invention are formed without the help of other tools, have regular shapes, consistent sizes and smooth surfaces, have no hammer stamp flaw, and are easy to process. Manufacturing speed of the cutters is greatly improved, labor intensity of workers is reduced, product quality is improved and weight error of flour wrappers is decreased.
