Arc-shaped sheet metal part forming method and wing

The invention belongs to sheet metal part manufacturing, and relates to an arc-shaped sheet metal part forming method and a wing. The arc-shaped sheet metal part forming method is characterized in that after process preparation, a part is blanked; then, first-time stretching forming is carried out, and the time is pre-stretching; after the pre-stretching is finished, carrying out secondary winding and bending stretching on a winding and bending mold, so that the parts are attached to the mold; and then heat treatment is carried out, stretch bending and shape correction are carried out according to specific compensation tension after heat treatment, annealing treatment is carried out, and finally sheet metal shape correction inspection is carried out. According to the technical method, the manufacturing precision is high, the forming surface manufacturing smoothness is good, the problems that the arc-shaped sheet metal part does not abut against a tire locally and the surface quality is poor can be effectively
