Abstract

The invention relates to a spanwise prestressing method for improving the shot peening forming of a high-rib integral wall plate. Including S1: wrapping and clamping the end of the rib far away from the wall panel slab; S2: installing the wall panel slab on the prestressing tool, from the wall panel slab close to the rib Prestressing is applied to the other side of one side, and the prestressing state is maintained; S3: Shot peening is implemented, and the high-strength integral wall plate is shot peened according to the shot peening path and forming requirements. The shot peening effect and service life of the high-reinforced integral wallboard are improved.

Description

technical field [0001] The invention relates to the technical field of shot peening, in particular to a spanwise prestressing method for improving the shot peening of high-rib integral wall boards. Background technique [0002] At present, shot peening technology is widely used in the aviation manufacturing industry, and has become the first choice or even the only forming method for large and medium-sized aircraft. The overall wall panels of ARJ21 and other wings adopt shot peening technology. [0003] Usually, the high-reinforced integral wall panels, especially the hyperbolic high-reinforced integral wall panels, adopt the prestressed shot peening process. Only domestic applications include the forming of high-reinforced integral wall panels for wings such as AG600 amphibious aircraft. [0004] At present, it is difficult to shot peen the double-convex and high-rib integral wall panels with large curvature, which seriously affects the application of double-convex and hig...
