The utility model discloses a suppressing tooling of a wind-guiding blade and belongs to the technical field of mold tooling. The suppressing tooling of the wind-guiding blade mainly comprises an upper mold of the tooling and a lower mold of the tooling. The upper mold of the tooling comprises a locating board, suppressing round steel and a steel plate. The suppressing round steel is connected with the bottom portion of the locating board through the steel plate. Two locating pin holes are formed in the locating board, and the center of the suppressing round steel and the centers of the locating pin hole are in the same plane. The lower mold of the tooling comprises a radian molding plate and a locating base seat arranged at the bottom portion of the lower mold of the tooling, and the center of the radian molding plate and the center of the locating base seat are in the same line. The suppressing tooling of the wind-guiding blade has the advantages that the radians of the steel plate can be better controlled, working intensity of workers can be reduced and working efficiency is improved.
