RESEARCH ON THE INFLUENCE OF FORGING PARAMETERS ON THE SHAPE OF THE FORGING

Abstract

The work analyzes the influence of the initial forging parameters on the final shape of the forging, and the research in this article makes it possible to understand how the metal flows during deformation, as well as to construct the dependences of the geometric shape on the initial parameters of the forging of the part. These dependencies will allow not only to predict the flow of the metal and the nature of the deformation, but also to evaluate and analyze the influence of specific parameters on the geometry, quality and physical and mechanical properties of the forging. The work considers the process of modeling the forging of valve bodies with complex flow and deformation of the metal, as well as the possibility of obtaining various forging parameters, such as temperature fields, deformation distribution, deformation intensity and structure, as well as the ability to calculate force parameters, energy consumed and time for deformation of the forging. The influence of forging parameters, namely the feed rate, the degree of deformation of the canting angle and the shape of the deforming tool on the final geometry of the forging, namely on the forging of the inner diameter and the increase in the forging length of the valve body, on the occurrence of weights in the end plane of the forging, on the displacement of the forged diameter relative to the forging axis and on the occurrence of forging defects, is considered. The main geometric dimensions of the forging after deformation are constructed and measured, and conventional designations are made for all sizes of the deformed forging. The deformation zones of the forging are considered and graphical dependences of the forging geometry on the initial forging parameters and the geometry of the workpiece are constructed. Several schemes for forging shut-off valve bodies are investigated.
