GEOMETRIC AND MATHEMATICAL ANALYSIS OF FORGING TOOLS FOR ROLLER BODIES IN BEARINGS

The scope of research of this paper is designing, modelling and analysis of tools for cold forging of rolling bodies of roller bearings. Basic principles of metal processing using plastic deformation are presented for better understanding of the forging process. Geometric tool modelling required knowledge of interconnections between individual tool elements, and their role in the forging process. The paper presents geometric and mathematical modelling of tools, and simulations of their operation. This presented a complete overview of movements of individual tool elements, which improved its functionality. In order to minimise errors in tool making and its stability, stress analysis and material yield at forging were taken into consideration.
