THEORETICAL ANALYSIS OF ROTARY DRAWING PROCESSES FOR TUBE BILLETS USING DIFFERENT METHODS

Abstract

The article deals with methods of theoretical analysis of rotary drawing processes from tube billets, which are widely used in modern industry to obtain parts with high accuracy and improved mechanical properties. Rotary drawing is a process in which tube billets are deformed under the action of a rotating tool, which leads to their drawing and geometry change.  Various methods of theoretical analysis are used to investigate this process, including analytical solutions, numerical modeling and finite element methods. Analytical methods provide simplified solutions to estimate the basic process parameters such as deformation forces, stress 
and strain distribution in the workpiece. Numerical methods, including finite element methods, provide a more detailed and accurate analysis, allowing complex workpiece shapes and multilayer materials to be considered, as well as predicting residual stress distributions. The paper focuses on the influence of key parameters of the rotary drawing process, such  as tool speed, clamping force, process temperature and material properties of the workpiece.  Possibilities of increasing the accuracy and efficiency of the process, as well as improving the mechanical characteristics of the finished product are considered.
