The invention discloses a manufacturing method of a tail pipe decorative frame body. The manufacturing method comprises the steps that 1, stretching, trimming and flanging are conducted according to the design requirement of the decorative frame body to form a decorative frame body blank; 2, sharp corner die pressing is conducted on the round corners of the decorative frame body blank through a sharp corner die, so that the round corners of the decorative frame body blank are converted into linear included angles, and a decorative frame body to be punched is formed; and 3, punching is conducted through a punching die along the linear included angles and perpendicular to the interior of the decorative frame body to be punched, and the tail pipe decorative frame body is formed. The method has the advantages that the round corners are subjected to included angle film pressing to form the linear included angles, then the tail pipe decorative frame body can be machined and manufactured through punching of the punc
