Abstract

The possibility of obtaining parts with complex curved surfaces is estimated. The features of shaping such parts by the bending process are analyzed using the example of the “flap” part using the LS-DYNA CAE system. Using modeling, it was found that under compressive stresses on the side surface of the part, corrugations occur due to the movement of metal into the gap between the punch and the die. The gap parameters have been determined, which exclude an unacceptable manufacturing defect. Experiments have been carried out on the developed die tooling.
