Deformation of the flange in the deep drawing of box-shaped parts was studied. The forming of box-shaped parts was simulated through numerical simulation software DYNAFORM, and hardness of box-shaped parts was measured with a hardness tester. The results shows that, the sheet thickness near the midpoint of straight edge is more lager than near the corner, and flow stress is small, indicating that plastic deformation is not sufficient. Sheet thickness of box-shaped parts of large aspect ratio is relatively large, and sheet flow is difficult, which is not conducive to forming. In the experiment, the hardness of rounded corner part is significantly greater than two adjacent straight edges at the same height, which shows that material flow of the rounded corner part is good and hardening phenomenon is obvious, and the maximum hardness is near the entrance to the die corner. The flange deformation of box-shaped parts of the experimental and numerical simulation is the same.
