摘要
随着船舶、飞机、汽车等行业快速发展,产品更新换代加速,产品的品种增多,所需要的板料弯曲成形也越来越多。不同于传统的薄板冲压成形,3D自由复杂曲面厚板成形一直是金属成形领域的挑战。研究发现,不同板材成形技术都有优缺点,为了能够更好的发挥不同成形技术之间的优势,许多学者对不同成形技术相互结合的复合成形工艺进行了研究。为了减少回弹对板材成形精度的影响,提高板材的成形极限,金属成形领域已经探索了一系列技术,主要是通过外加辅助载荷实现。辅助载荷主要分为两种:一种是辅助热载荷;一种是辅助力载荷。本文对金属板材的复杂曲面复合成形加工方法进行了总结研究。
With the rapid development of shipbuilding,aircraft,automobile and other industries,product upgrading accelerated,product varieties increased,the need for plate bending forming is also more and more.Different from traditional sheet metal stamping,3D thick plate forming with free complex surface is always a challenge in metal forming field.It is found that different sheet metal forming technologies have advantages and disadvantages.In order to better play the advantages of different forming technologies,many scholars have studied the composite forming technology combined with different forming technologies.In order to reduce the impact of springback on sheet metal forming accuracy and improve the forming limit of sheet metal forming,a series of technologies have been explored in the field of metal forming.Auxiliary load is mainly divided into two kinds:one is auxiliary thermal load;One is the auxiliary force load.In this paper,the composite forming method of complex surface of sheet metal is summarized.
