摘要

Flanging is quite actively used in the manufacturing of workpieces with necks. Its prevalence in production explains the fact that there is a huge number of Russian and foreign researches discussing this operation, which unfortunately do not take into account the Influence of the mechanical properties of the blank. Thus, the study of this process, in relation to the anisotropy, is essential. This article deals with the flanging of a sheet semi-finished workpiece with a hole made at the intermediate stage of deformation In a radial die. The research investigates the effects of such important parameters as flanging coefficient and radius of working tool curvature at the maximum force that occurs during the flanging. The obtained results of theoretical studies can be used to create new technologies for pressure treatment of sheet flange parts, the main stamping operation of which can be the flanging of flat pieces that take into account anisotropy.
