Bending of sheets and profiles on a four-roll machine for rocket bodies, tubular and frame products. Part 10

Abstract

The theory of stamping is developed taking into account the anisotropy and hardening of the workpiece. The calculation of the parameters of the deformed-stressed state of the billet is carried out using the example of bending on a roller machine or in a die. Deformations, stresses and forces acting on the billet from rolls or die tools are studied by CAD/CAE modeling. The criteria for crack formation, low accuracy and excessive springback of the part after processing are determined, recommendations for their elimination are given. Keywords: stamping, anisotropy, billet, bending, roll machine, die, CAD/CAE modeling. dr_zharkov_v_a@mail.ru
