Abstract: The presented work is devoted to analysis of the stress-strain state and restoring repair of stamping tools, intended for forming large-diameter tubes, based on computer modeling. Stamping tools includes in its membership a stamp holder and eight interchangeable cast-iron liners, which have a cylindrical surface with radius, equal to the radius of the tube, and are established on the stamp holder. The load out of the deformed billet of tube is transferred on the cylindrical surface of the tool and further to the bearing surfaces of the stamp holder. Contact interaction occurs between the parts of stamping tools, and it affects on they stress-strain state. To solve the nonlinear boundary problem of elasticity theory is used a numerical finite element method.
Keywords: holder stamp, liner, low cycle fatigue, boundary problem, computer simulation
