The Mathmatic Modle for Analysis of Process Parameter of Bearing Ring by Cold Rolling

The cold rolling technology of bearing is a kind of cold forming technology by utilizing plastic deformation of metal. The final mechanical property of bearing ring depends on the deformation, In order to make bearing ring have good quality and obtain high prouction efficieny, this paper analyzes multiple rolling range in the machining,rang of the equipment, considers the equipment capacity and the deformation of ring blank, and then sets a mathematical model of process parameter in rolling. By the example analyzing, the mathematical model is reasonable, and the result is important for planning cold rolling technology.
