Experimental Study of Springback (Side-Wall-Curl) of Sheet Metal based on the DBS System 2019-01-1088

Springback is a common phenomenon in automotive manufacturing processes, caused by the elastic recovery of the internal stresses during unloading. A thorough understanding of springback is essential for the design of tools used in sheet metal forming operations. A DBS (Draw-bead Simulator) has been used to simulate the forming process for two different sheet metals: aluminum and steel. Two levels of pulling force and two die radii have been enforced to the experimental process to get different springback. Also, the Digital Image Correlation (DIC) system has been adopted to capture the sheet contour and measure the amount of side-wall-curl (sheet springback) after deformation. This paper presents the influence of the material properties, force, and die radius on the deformation and springback after forming. A thorough understanding of this phenomenon is essential, seeing that any curvature in the part wall can affect quality and sustainability. The data collected during this experimental procedure, in addition, to evaluate the springback characteristic of different sheet metals and is crucial for simulation validation within the automotive stamping industry. Moreover, it will provide a more thorough understanding of side wall curl, which will greatly benefit future part production.
