Martynov S. Improving of technology and tooling tubular parts in cold forging with internal flanges.

The object of the research is the cold forming processes tubular flanges. The aim of the work is an increase the efficiency of technological processes of cold forging parts with internal flanges. The methods of research and apparatus are the mathematical and physical modeling, methods of grid charts and mathematical statistics, experiments in the conditions of laboratories. Theoretical and practical results are the mathematical models for calculating the power parameters, recommendations for the improvement of technology and development of die tools. Novelty is the influence of the main factors on the power parameters of forming parts such as bushings with inner flange. Efficiency of implementation is the developed and transferred to industrial development of technology and die tools (a certificate of acceptance for development). Area of application is metal forming,. unit engineering and metallurgical enterprises, industrial research institutes.
