Title: Development of Algorithm and Calculation of Capillary Tube Deformations During Mandrel Extraction After Long-Mandrel Drawing
Abstract:
Cold drawing of tubes on a long movable mandrel is the only method for manufacturing precision capillary tubes with outer diameters less than 3 mm and wall thicknesses from 0.015 to 0.2 mm. After drawing, the tube tightly grips the mandrel due to residual stresses, making mandrel extraction a challenging technological operation. This study presents a developed algorithm for calculating capillary tube deformations during mandrel extraction using longitudinal rolling in reeling cassettes. A finite element method (FEM) based approach was implemented in the DEFORM-3D software package to model the reeling process. The developed algorithm enables calculation of reeling parameters for the entire range of capillary tubes specified in GOST 14162-79 from various materials. Experimental validation on a universal testing machine REM-100A confirmed the adequacy of the FEM model. The results provide practical recommendations for setting up reeling cassettes in industrial production of precision capillary tubes
