The bending forming process of aviation aluminum profiles has been widely applied in bending workpieces such as aerospace aircraft manufacturing. Bending machines are often used for the bending processing of key components that make up the aircraft frame, such as the edge strips on the aircraft frame ribs, the front and rear sections of the fuselage, and the engine nacelle. Their bending forming accuracy directly affects the aerodynamic shape of the aircraft. However, many parts with variable curvature, such as Z-shaped, L-shaped, T-shaped, U-shaped, or other shaped section bending parts, are generally formed by bending machines.
During the bending process of aerospace shuttle profiles, there are common problems such as wall thickness reduction, cracking, wrinkling, section distortion, and rebound, which require repeated correction through worker experience and trial and error methods. After the final shape is formed, manual calibration is also required. This method is costly, time-consuming, and difficult to ensure shape accuracy.
