摘　　要：为了提高生产率,降低成本,某型号冰箱竖梁改进了原来的工艺,采用了整体式的结构。该整体式的竖梁在进行双角"П"形件弯曲成形时,由于残余应力的释放,卸载后角部角度会回复,同时侧壁会卷曲,影响产品的精度。从数值模拟、实验研究两个方面对工艺难度较大的"П"形弯曲回弹规律进行探讨,确定影响回弹的诸多因素,并将影响回弹的因素与回弹量的关系进行量化分析,提出了一些减小回弹的方法,并将此研究结果用于生产的过程控制和零件质量控制。In order to reduce cost and improve efficiency, the technique of vertical beams of a certain refrigerator is modified and an integrated structure is introduced. In the course of dun angle H curve shaping, the degree of angle rebounds to a certain degree and the side wall frizzle. Thus the quality is affected. And the resilience disciplinary of I-i-shape curve shaping is explored from numerical modeling and relation between the influential elements on resilience and the quantity is also analyzed in quantity. Measures to reduce the resilience are proposed. The result of this research is applied in controlling the production course and the quality.
