Three-dimensional free bending is a new and an advanced forming technology to manufacture the complex metal hollow components with continuously varying radius. In this study, the free bending process of copper bending tubular component was numerically investigated through finite element method using ABAQUS finite element code. The motion trace scope of bending die and stress variation in free bending process as well as the calculated correction factor (Km) of copper and the correction factor (Kc) for the clearance between tube and bend die were also determined. Moreover, the effects of the key process parameters including the clearance between the tube axis and bend die axis (Δc), the distance between the center of the bending die and the head of guide sleeve (A) and the axial push velocity (v) on the forming quality of the tubular bending components were studied as well. Finally, the bending test of copper tube was also carried out on the basis of the optimal simulation results. The results obtained from finite element modeling gave a very good agreement with the dimensions of the bending components. Furthermore, there was no obvious cross section distortion, excessive thickening and thinning of wall thickness of the formed tubular components. It’s concluded that the three-dimensional free bending technology is a novel forming process used to manufacture a sound complex 3D hollow component with asymmetric cross-sections and continuous varying radii. |
