Abstract

The basic principle of cold roll-beating forming was described, finite element model of rack cold roll-beating was established by ABAQUS, the forming process, equivalent strain and stress were analyzed, at the same time, a path on tooth space section was established and changing trend of stress was analyzed in the path. The forming force of rack roll-beating was analyzed. The preliminary experiment of rack cold roll-beating was carried out, and the experiment and simulation analysis results were compared to verify the validity of the finite element analysis. This research establishes a good basis of the theory and application for rack single-point cumulative forming.
