摘要
相比于直型材,铝合金弯曲型材更适用于日益复杂的部件形状并能更好地满足轻量化需求,具有提升部件结构强度和刚度、节约空间及增加工业设计自由度等优点,在汽车、高铁和航空航天等领域具有广泛用途.相较于传统冷弯成形技术,挤压弯曲一体化成形技术在生产弯曲型材方面具有流程短、精度高、缺陷少等优点,因而受到广泛关注.重点综述了基于外部弯曲装置和材料差速流动的挤压弯曲一体化成形技术的研究进展,分析并总结了不同挤压弯曲一体化成形技术的原理及发展现状,对比了不同挤压弯曲一体化成形技术的优缺点,最后展望未来发展趋势及其研究方向.
Abstract
Compared with straight profiles,aluminum alloy curved profiles are more suitable for increasingly complex component shape and better fulfill the demand for lightweight construction,which have the advantages in enhancing structural strength and rigidity,saving space and increasing industrial design freedom,and are widely used in the fields such as automobile,high speed train and aerospace.Compared with the traditional cold bending forming technology,extrusion-bending integrated forming technology has the advantages of shorter process,higher precision and fewer defects,therefore,it has received widespread attentions.The research progress of extrusion-bending integrated forming technology,which is based on external bending apparatus and differential velocity material flow,was compre-hensively reviewed.The principles and current development status of various extrusion-bending integrated forming technologies were ana-lyzed and summarized,and the advantages and disadvantages of these technologies were compared.Finally,the future development and research trend were anticipated.
