Elastic Rebound Research in Cold Bending Processing on Aluminum Alloy Plate

Taking 5083 aluminum alloy plate in cold bending test for example, according to the different measuring results of the elastic rebound angle, the bending properties of 5083 aluminum alloy is studied.And the data statistics and analysis are finished,The experience curve of "the rebound angle with R/s" is drawn. So not only it clearly provides the theory basis for the thermal deformation of the workpieces in cold bending,but also it gives the methord of expanding range of the cold working processing in order to decrease the heating deformation to some extent.
