Abstract
In the article, the authors present a method of constrained bending of sheet parts with curvilinear sides by the elastic media. They describe the process of constrained bending and the scheme of the experiment. After the first transition, a part with thinning in the radius and high side springing is obtained. The second transition, on a low-height rigging, a wave of excess material is first formed in the radius zone, which settles on the contour of the mandrel with a set of thickness. The stages of forming a semi-finished product are given. The experiment showed the feasibility of constrained bending of curved sides, wall thickness measurements showed that the second transition results in a thickening of the part wall. Finite element modeling of a constrained bend is performed to study the effect of excess of the Board on the thickening in the bending zone. Numerical studies of deformation processes have been carried out. An example of a diagram of the part thickness change for various deformation stages as a result of numerical studies is given. Dependence of part height exceeding with loss of stability during shaping is established. Examples of defects - folds are given.
