Analysis of tube deformation process in a new pilger cold …
Cold rolling of tubes in pilger mills is a cyclical process that is commonly used in manufacturing of tubes made of hardly deformable alloys. In the classic solution [1], [2], the rolling stand is mobile and moves to-and-fro, and the rollers move with the stand, while turning in opposite directions.A circular groove is cut in the roller, so that in the …

A numerical model was established to calculate the cycle feed rate through studying the case of a cold pilger mill with the 304 stainless steel pipe. Firstly, the precise constitutive equation of 304 stainless steel was obtained through nonlinearly fitting the true stress–strain data from unidirectional tensile test. Then, the numerical method to …
