Research progress on extrusion-bending integrated forming technology of aluminum alloy profiles
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.
