Abstract
In this paper, the simulation model of the cold rolling process of the deep groove bearing inner ring was established by using the finite element software Deform-3D. The numerical calculation of the model was made with different process parameters. The law of the influence the process parameters on the rolling force was analyzed. The deformation mechanism of the cold rolling process of the inner ring was revealed. The research indicated that the feed rate of idle roller had the greatest influence on the cold rolling process. Finally the experiment using the XS-50 precision CN ring rolling machine was carried on and a finished product of the inner ring of a better quality came out. It verified that the numerical simulation could provide theoretical basis for the practical production process.
