Документ Экспериментальные исследования режимов кузнечной протяжки заготовок с обкаткой в комбинированных бойках(НТУ "ХПИ", 2013) Кухарь, В. В.; Василевский, О. В.The methodic of experimental research of form-changing and force parameters during stretch forging of billets with rolling to diameter by combined anvils is worked and realized out. The depends of changing of force parameters, geometric characteristics and optimal modes of deformation of billets during stretch forging by rolling in combined anvils with different values of press upsetting and angles of rotation of billets around far axe are determinates.Документ Экспериментальные исследования технологии производства порошковых лент(НТУ "ХПИ", 2013) Грибков, Э. П.; Данилюк, В. А.Results of theoretical and experimental studies of production powder electrode tapes are given in article by a rolling method. It is established that the exception of a spillage of the powder core of a metal cover when transporting and melting, requires use of the production technology of powder tapes which is in preliminary rolling of components of the core before loading the subsequent layer in a metal cover that allows to increase the relative density of the core and keeps thus the size of the powder fraction.Документ Выбор и обоснование методов теоретических исследований процесса деформирования осесимметричных заготовок(НТУ "ХПИ", 2013) Драгобецкий, В. В.; Пузырь, Руслан Григорьевич; Аргат, Роман ГригорьевичIt is shown that the methods of theoretical study of metal forming processes must be justified from the standpoint of the expected accuracy of the obtained results and the physical nature of the phenomena occurring in the deformation zone, which arise depending on the method of focus, the geometry of the tool and the workpiece, the properties of deformed metal, conditions of friction between the contacting surfaces. The complexity of the mathematical models and the implementation of the algorithm in the final- result, the adequacy of the solutions depends on the adoption of a simplified and schematic processes of deformation.Документ Ковка поковок типа валов с продольным сдвигом специальными бойками(НТУ "ХПИ", 2013) Алиева, Л. И.; Жбанков, Я. Г.; Станков, В. Ю.Influence geometric parameters of dies on strain state of billet and defects formation was established. Determined that forging of cylindrical billet by special dies must be done with minimal clearance and relative height deformation 10-15% of billet diameter. Forging of flat billet must be done by special dies with sloping stage. This provides in further correction of billet the high quality surface.
