摘要：

针对“日”字截面型材在绕弯成汽车防护梁过程中产生的截面变形缺陷，基于自主研发的绕弯装置，利用有限元分析软件ABAQUS和正交试验模拟方法，探究了工艺参数中绕弯半径，芯棒的芯头数及芯模间隙对截面变形的综合影响规律。结果表明：最大变形截面位置受芯头个数的影响；截面的各变形量都随绕弯半径和芯头个数的增加而减小，随芯模间隙先减小后增大；工艺参数组合为绕弯半径600 mm，芯头数为2，间隙为0.75 mm的防护梁成形方案减轻截面变形效果较好，并且通过试验验证了模拟结果的有效性。

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
