The process of obtaining a continuously cast deformed workpiece from aluminum alloy AD0 on a casting-forging module made in the form of a mold with movable walls is considered. The scheme of work is given and the operation of the modification of the device is described, in which one striker plate, which has an inclined and vertical sections, is movable, and the second plate has a vertical arrangement and is fixed. A mathematical model for obtaining a metal workpiece is described. The behavior of the metal is assumed to be viscoplastic. The phase state is determined by temperature. At the boundaries of metal contact with tooling, heat exchange is performed, contact friction is taken into account. The numerical method of solution involves partitioning the computational domain by a system of orthogonal surfaces. The time step corresponds to the angle of rotation of the movable striker plate. The numerical method for solving the problem consists of two stages at each time step. At the first stage, the problem of heat conduction is solved taking into account the initial and boundary conditions, at the second one the problem of determining the stress-strain state, taking into account the computed temperature field, initial and boundary conditions. As a result of the computational experiment, the distribution fields of temperature and stresses in the region of metal deformation were obtained.
Keywords: casting and forging module, metal crystallization, stress-strain state, mathematical model, temperature, workpiece deformation.
