Workpices with different cross sections in the orthogonal direction along the height can be produced by crimping of hollow cylindrical blanks. This operation is highly productive and makes it possible to obtain various types of connectors. This article discusses simultaneous crimping and thinning of the workpiece wall at the exit from the deformation zone. During crimping, the thickness of the workpiece grows in the deformable part. In view of this, significant stresses may arise in the deformation zone. Therefore, selection of process parameters that provide the best stress state of the products is relevant. This article presents a study of the stress state in the combined process of crimping with wall thinning.
