Information × Registration Number 0200U001863, 0198U001354 , R & D reports Title Development of the theory and methods intensification of manufacturing tubular and hollow of products from high-strength alloys popup.stage_title Head Steblyuk V.I., Registration Date 05-04-2000 Organization National technical university of Ukraine "Kiev polytechnic institute" popup.description2 Object of research: direction intensification shaping of hollow products with replaceable thickness of walls and bottom. The purpose of research: intensification of processes shaping of hollow products with the attitude of thickness bottom and walls it is more 4...5. A method of research: the theoretical analysis of the strenuous-deformed condition of the center of deformation and estimation of boundary factors shaping in process of use of a resource of plasticity. In work the theoretical and experimental estimation of technological opportunities of manufacturing of deep hollow products (with the attitude of depth to a diameter more than 3...4) with a significant difference of thickness bottom and walls by methods combined drawing from previously shaped of preparations is executed, that allows considerably to reduce (in 3...4 times) duration of a work cycle, resources deprived and adverse ecological loading by an environment. Area of application: manufacture of special engineering Product Description popup.authors popup.nrat_date 2020-04-03 Close
