Abstract:

To solve the cross-section deformation defects in the process of rotary draw bending the profile with “日”-shaped into the automobile protective beam, based on the self-developed bending device, the finite element analysis software ABAQUS and the orthogonal test simulation method are used. The comprehensive influences of the process parameters on the cross-section deformation, including bending radius, number of cores and core mold gap are investigated. The results show that the position of the maximum deformation section is affected by the number of cores, each deformation of the section decreases with the increase of the bending radius and the number of cores, first decreases and then increases with the die gaps. When the bending radius is 600 mm, the number of cores is 2, and the gap is 0.75 mm, the effect of reducing cross-section deformation is better, and the validity of the simulation results is verified by experiments.

Key words: manterial synthesis and processing, rotary draw bending forming, profile with “日”-shaped section, sectional deformation defects, orthogonal experiment
