Parameters of the Deformation Containment Volume at the Backward Stroke of Cold-Die-Pilgering and Cold-Roller-Pilgering Mills When Feeding the Billet in Either Positions of the Stand

The results of research concerning the development of the theoretical foundations for determining the value of pipe compression by wall thickness in the deformation site, during the reverse working flow of the cage, the cold pilger rolling mill of pipes are presented. Simplified dependencies are derived in the work to calculate the compression parameters during the reverse working stroke of the rolling stand. The proposed dependencies do not take into account the elastic deformations of the rolling mill stand. This will be associated with the further development of the method for calculating the deformation parameters of the considered case of conducting the cold pilger rolling process.
