Abstract
In this paper, we present the results of a study of the process of helical rolling of pipes using a deformation-geometric model based on block algorithms. The algorithms of the mathematical model in the form of a block structure allow the introduction of new or replacement of existing blocks, taking into account the influence of one or another factor on the pipe rolling process (for example, the feeding and rolling angles). Simulation and study of the deformation focus shape during continuous flashing and rolling of the hollow billet was carried out taking into account the shape and parameters of the working tools used in the elongator, the shape and size of the contact surface area of the deformable metal and rolls, in working conditions of industrial injection molding machine 5-12'’. The paper suggests CAD system based on simultaneous solid modeling in Compass-3D, Autodesk Inventor, SolidWorks, ANSYS or DEFORM3D environments. The proposed methods, taking into account the simplicity and high accuracy of the constructions, allow to conduct studies of the main parameters of the process efficiently and with visualization, which leads to the obtaining of necessary data. In addition, these products contain advanced tools for creating user libraries in all major programming languages. The accuracy of calculation of the energy-force parameters of the process, the geometric parameters of the shells and the oscillations of their values during simulation and in the production experiment are estimated. The modeling of the rolling process made it possible to explain the influence of the technological parameters of the rolling process on the quality and accuracy of the obtained shells and to develop a method for determining the exact process parameters and rational calibration of the tool. Modeling of the rolling process allows the analysis of the process and the development of corrective actions.
