Markevych A. Improvement of the technology of vibration drawing of refractory metal wire under the conditions of reciprocating motion of a straining tool

Object - the processes of vibrational deformation by wire drawing of refractory metals; the purpose - the creation of techniques and methods for improving the technology of drawing of refractory metals on the basis of the obtained analytical dependencies for determination of power characteristics of backwater and drawing with superimposed axial reciprocating vibrations; novelty - first energy method analytical dependences for calculating the effort of pushing and drawing, which gave the possibility to design efficient technological transitions, and to determine the required capacity of the equipment; updated theoretical relations for the longitudinal stability when pushing rod and the drawing, which helped to intensify the existing methods of drawing refractory metals; further development of the study of low frequency vibration deformation of refractory metals, as well as the optimal fiber angles, thus improving the uniformity of the deformation of bars and to reduce the additional friction losses.
