Abstract:
Hemming is a crucial step in the process of merging between automotive inner and outer panels. Bending limit is an important criterion to evaluate the hemming performance of aluminum sheets. The 180° three-point bending tests of nine kinds of different performances and batch import automotive aluminum sheet 6016 were carried out, and the influences of mechanical properties, aging time and pre-stretching on hemming performance were studied systematically,which provided a main foundation on controlling the quality and process of automotive aluminum sheet 6016. The results show that there is little influence of the elongation and hardening index on the hemming performance of automotive aluminum sheet 6016, while there is significant influence of material anisotropic, aging time and pre-stretching on hemming performance of automotive aluminum sheet 6016.
