Description

мы включают в себ  магнитно-стрикционные .ультразвуковые прео разователи 9 и 10 и концентраторы 11 и 12 колебаний.We include magnetic-striction ultrasonic transducers 9 and 10 and concentrators with 11 and 12 vibrations.

Токрпровод ща  жила или заготовка поступает в рабочую зону, где осуществл етс  непрерывное наложение оболочки посредством продавливани  материала оболочки через профилирующее отверстие матрицы 2 при непрерывной передаче синфазных осевых колебательных движений наружным поверхност м дорна 3 и матрицы 2 от магнитно-стрикционных преобразователей 9 и 10 через концентраторы 11 и 12 колебаний.A conductive conductor or billet enters the working area, where the shell is continuously superimposed by pushing the sheath material through the core hole of the matrix 2 with continuous transmission of in-phase axial oscillatory movements to the outer surface of the core 3 and the matrix 2 from the magnetic-striction converters 9 and 10 through concentrators 11 and 12 vibrations.

Взаимодействие колеблющихс  синфазно на ультразвуковой частоте дорна 3 и матрицы 2 создает стабильное во времени и равномерное по периметру накладываемых оболочек давление материала в зоне между дорном 3 и матрицей 2, а также резко снижает сопротивление движению перерабатываемого через формующий инструмент материала .The interaction of oscillating in-phase at the ultrasonic frequency of the mandrel 3 and the matrix 2 creates a stable in time and uniform pressure around the perimeter of the shells of the material in the area between the mandrel 3 and the matrix 2, and also drastically reduces the resistance to movement of the material processed through the forming tool.

Снижение сопротивлени  истечению перерабатываемого материала обеспечивают существенное увеличение линейной скорости наложени  оболочек. Стабильность давлени  материала в зоне наложени  оболочек во времени и равномерность распределени  его по периметру оболочек снижает предельные отклонени  наружного диаметраThe reduction in resistance to the outflow of the processed material provides a significant increase in the linear velocity of the shells. The pressure stability of the material in the overlapping zone of the shells over time and its uniform distribution along the shells perimeter reduces the maximum deviations of the outer diameter.

оболочек от их номинального значени  по длине издели  и обеспечивает улучшение их равностенности.shells from their nominal value along the length of the product and provides an improvement in their uniformity.
