Forming device and method suitable for self-adaptive pressurization of composite airfoil

The invention relates to a forming device and method suitable for self-adaptive pressurization of a composite airfoil. The forming device comprises an upper die, a lower die, fastening screws, compression springs, transverse partition plates and longitudinal partition plates. Transverse partition plates and longitudinal partition plates are arranged above the upper die and below the lower die, and are fixedly connected; the upper die and the lower die are connected through a fastening screw, and the fastening screw penetrates through the transverse partition plate. And the compression spring is positioned between the transverse partition plate above the upper die and the end part of the fastening screw. In the composite material forming process, self-adaption to the viscosity change of the resin in the pressurizing process of the prefabricated part can be achieved, the fiber deformation phenomenon caused by instantaneous rapid pressurizing is avoided while a large amount of production time is saved, and the p
