Abstract

Gozhii S., Myronenko V. Prerequisites for the creation of energy-efficient technologies and equipment for orbital stamping by rolling.

Scientific studies of the processes and equipment of orbital rolling stamping are conducted at the Department of Aircraft Production Technology of the Scientific and Educational Mechanics and Mechanical Engineering Institute of the National Technical University of Ukraine "Ihor Sikorskyi Kyiv Polytechnic Institute" from the 70s of the last century to the present. During this time, sufficient experience has been accumulated in the creation of energy-efficient technologies and equipment for orbital stamping by rolling. All scientific developments are created on the basis of qualitative effects of the process and emphasize its unique possibilities and perspective of application. Given the fact that the modern tool for researching metal pressure processing processes is computer modeling technology that uses the finite element method, the priority remains experimental research, thanks to which most of the qualitative effects of orbital stamping reflected in the article were recorded. Special attention was paid to the effective positive application of the qualitative effects of rolling stamping. In particular, such an effect as the formation of a zone of action of tensile stresses can be energy-efficiently used for the formation of a central cavity. And the eccentric application of the deformation force can be effectively balanced, which will not only reduce the load on the equipment, but also create the basis for a number of original technologies. Appropriate technological and design solutions, based on the results of scientific and experimental research of the process, are introduced into production and laid as a basis for writing this article.
