“…In the literature, several papers have been published where the roll separation force and deformation history during pilgering have been studied using experimental and/or computational methods [2][3][4][5][6][7][8][9][10][11][12][13][14]. However, there are only a few studies where the influence of roll stand deflection and/or the displacement of the mandrel and the tube are included [4,5,6,10].…”

Abstract.A three-dimensional finite element model of cold pilgering of stainless steel tubes is developed in this paper. The objective is to use the model to increase the understanding of forces and deformations in the process. The focus is on the influence of vertical displacements of the roll stand and axial displacements of the mandrel and tube. Therefore, the rigid tools and the tube are supported with elastic springs. Additionally, the influences of friction coefficients in the tube/mandrel and tube/roll interfaces are examined. A sensitivity study is performed to investigate the influences of these parameters on the strain path and the roll separation force. The results show the importance of accounting for the displacements of the tube and rigid tools on the roll separation force and the accumulative plastic strain.

Cold pilgering is a complex forming process used to produce seamless tubes, posing significant challenges in material modeling due to its non-proportional loading history and extensive accumulated plastic strain. In this study, a temperature- and plastic strain-dependent Chaboche model for 316 L stainless steel was developed and calibrated. To simulate the complex loading conditions, unique alternating compression-compression tests were conducted, and the model parameters were optimized accordingly. The calibrated model was integrated into a thermo-mechanical finite element simulation of the cold pilgering process, resulting in improved accuracy in predicting stress-strain responses and yield stress evolution. Close agreement with experimental tensile tests of the final tube was demonstrated, illustrating the model’s capability to predict hardening behavior during cold pilgering. Valuable insights and a practical modeling approach for enhancing the simulation and optimization of cold pilgering processes are provided by this work.
