Forming and Research Status of Overlapping Sheets of Light Alloy Sheet Metal Parts
The overlapping sheets forming refers to covering one or both sides of the forming sheet with the sheets of the same or dif-ferent materials(called overlapping sheet).By the overlapping sheet forming,the force state and deformation law of the forming sheet are changed,the forming performance and forming quality of the forming sheet is further improved.The overlapping sheets forming is one of the common forming methods for complex-shaped light-alloy sheet metal parts.During the forming process,the performance of the overlapping sheet and the law of action on the forming sheet are the key to the feasibility of the forming of light alloy sheet metal parts.it introduces the forming principle of overlapping sheets of light alloy sheet metal parts,summarizes the in-fluence of the thickness of the overlapping sheet,the mechanical properties and the interface friction with the forming sheet on the forming process and the current research status,and gives an outlook on the existing problems and development trends.
