Abstract

Springback is considered as one of the most common problems in metal forming processes, which poses an inaccuracy of product angle during assembling of parts. The estimation of the springback is difficult to predict for formed parts since it depends on many factors such as the mechanical properties, the sheet thickness, and the die angle. In this work, an experimental investigation of drawbead for different material thicknesses and the use of different lubricants such as grease, oil and wax have been studied and analyzed. Samples of aluminum specimens with 120 mm length, 30 mm width and thickness of 0.5, 0.7 and 0.8 mm were selected in this study. Design and manufacturing of double bending die with profile of Circular, Rectangular, and Triangular have been applied firstly without drawbead and then with drawbead. The results showed that in a given profile configuration, the springback reduced with existing the drawbead
