Shkira O. Improving the processes of stamping parts with a flange and the appendage on the basis of the combined extrusion methods

Object of research - process precision forging extrusion. Purpose - to increase the efficiency of technological processes of cold forming on the basis of the development and application of the combined extrusion methods. Research Methods - Energy power balance method, finite element method, the method of physical modeling and strain measurement technology for measuring forces, grids method for determining the strain state of preparations. Theoretical and practical results - based on established patterns of power and deformation modes designed a technique of designing process trilateral extrusion parts with flange and process, based on mathematical models developed software that allows you to determine the reduced pressure and forming processes triangular extrusion parts with flange and SHOOTS taking into account the actual geometry of the process and the degree of deformation. Novelty - on the basis of theoretical studies, a mathematical model of a combined three hundred-sided extrusion parts with flange and process, allowing to define the power mode of deformation and gradual shaping slozhnoprofilirovannyh parts, based on the results of the analysis of tense-deformed state, evaluating the degree of plasticity of the resource consumption of the workpiece material during extrusion hollow flange components and outgrowth. Introduction - new processes and tools for stamping parts with flange and process, have been tested and approved for implementation in production. Scope - metal forming, precision forging.
