Устройство работает следующим образом .The device works as follows.
Электроакустический преобразовател ь 1 создает механическое продольное колебание . Волновод 2 подводит механические колебани и статическое сварочное давление Рев к свариваемым детал м. Энерги ультразвуковых (УЗ) колебаний распростран етс в полимере от волновода к опорному узлу. При этом благодар высокому модулю упругости жестких термопластов и низкому коэффициенту затухани ультразвуковые колебани лишь незначительно ослабл ютс при проходе через корпус 7 и их энерги выдел етс , в основном, на границе раздела корпуса 7 и подложки 8, что обеспечивает получение сварного соединени .Electroacoustic transducer 1 creates a mechanical longitudinal oscillation. Waveguide 2 supplies mechanical vibrations and static Roar welding pressure to the parts to be welded. Ultrasonic (UL) vibrations energy propagates in the polymer from the waveguide to the support node. However, due to the high modulus of elasticity of rigid thermoplastics and the low attenuation coefficient, the ultrasonic vibrations are only slightly weakened when passing through the housing 7 and their energy is released mainly at the interface between the housing 7 and the substrate 8, which provides a welded joint.
Опорный узел служит дл фиксации свариваемых деталей, в частности корпуса и подложки 8 и выполнен таким образом, чтобы свести к минимуму воздействие ультразвуковых колебаний на компоненты 9, помещенные внутрь корпуса 7, и отбираемую от акустического узла и свариваемых деталей колебательную мощность. Наличие сло 3 из высокоэластичного материала (резины ) при приложении сварочного давлени обеспечивает равномерное соприкосновение кромки корпуса 7 с подложкой 8 и рабочего торца волновода 2 с корпусом, необходимое дл получени герметичного шва. При этом верхний дополнительный слой 5 плотно прижимаетс к подложке 4 ы служит в качестве демпфера колебаний подложки . Этот слой изготавливаетс из матеThe support assembly serves for fixing the parts to be welded, in particular the housing and the substrate 8, and is designed to minimize the effect of ultrasonic vibrations on the components 9 placed inside the housing 7 and the oscillating power taken from the acoustic assembly and the parts to be welded. The presence of a layer 3 of highly elastic material (rubber) when welding pressure is applied ensures uniform contact of the edge of the housing 7 with the substrate 8 and the working end of the waveguide 2 with the housing necessary to obtain a sealed joint. In this case, the upper additional layer 5 tightly pressed against the substrate 4 s serves as a vibration oscillation damper of the substrate. This layer is made of mat
риала с хорошими прочностными и акустическими свойствами (титановые сплавы, сталь 45 и др.), его толщина на практике составл ет di 1,5-2 мм, что обеспечивает необходимую механическую прочность при соблюдении услови di AI . В слое 5 могут быть выполнены технологические отверсти дл прохождени элементов металлоарма- туры 10.A rial with good strength and acoustic properties (titanium alloys, steel 45, etc.), its thickness in practice is di 1.5–2 mm, which provides the necessary mechanical strength under the conditions di AI. In the layer 5, technological openings can be made for the passage of the metal fitting elements 10.

волны в его материале, опираетс на слой из высокоэластичного материала, что обеспечивает условие закреплени (дл продольной ультразвуковой волны), приближающеес к стержневой системе со свободным концом, что дает возможность свести к минимуму амплитуду колебаний подложки 8 и соответственно воздействие ультразвука на элементы металлоарматуры 10 и компоненты 9.the waves in its material are supported on a layer of highly elastic material, which provides a clamping condition (for a longitudinal ultrasonic wave) approaching a core system with a free end, which makes it possible to minimize the vibration amplitude of the substrate 8 and, accordingly, the effect of ultrasound on the metal fittings 10 and components 9.
