The research was conducted at the Department of Aircraft Technology and Design of the Educational and Research Institute of Mechanical Engineering of the National Technical University of Ukraine “Igor Sikorsky Kyiv Polytechnic Institute”. On the basis of performance of scientific subjects concerning compression of a tubular cavity preparation with formation of an internal cavity the most perspective schemes of such technological processing were investigated and technological and constructive elements of processes and the equipment were defined. Indicators such as quality (compliance of the product with the requirements of use) and its cost, process productivity, technical and economic characteristics and versatility of the equipment were taken into account. To experimentally confirm the chosen direction of implementation, first of all, experimental equipment was designed and the technical process was modeled according to each of the proposed schemes.

A characteristic feature of the details considered in the article is the increased diameter of the flange. At the Department of Aircraft Production Technology of the Scientific and Educational Mechanical and Mechanical Engineering Institute of the Kyiv Polytechnic Institute named after Igor Sikorskyi developed an original technological process for manufacturing products with a developed flange part using the positive effects of the progressive rolling stamping method. The method has energy-strength advantages over traditional methods of manufacturing parts with relatively thin structural elements. The center of application of such technologies is expanding more and more, but the basic technological calculations of process parameters have not yet been introduced widely enough into production practice. The proposed sequence of technological calculations and basic parameters of specialized installations for rolling stamping.
