Abstract

Изобретение относитс  к сварке пластических масс, а именно к устройствам дл  непрерывной ультразвуковой сварки. Цель - повышение прочности и качества сварного шва. Дл  этого устройство снабжено магнитострикционным преобразователем 1, трансформатором 2 упругих колебаний, сварным инструментом, включающим первый полый усеченный конус 3 изгибных колебаний и дополнительный полый усеченный конус 4 продольных колебаний, св занные через кольцевой сварочный наконечник 5, центральным стержневым элементом 6 продольных колебаний, который св зывает полые усеченные конуса 3 и 4 по плоскост м меньшего диаметра 7 и 8. При этом высота первого усеченного конуса равна или кратна 1/4 длины продольной волны, высота его боковой поверхности равна или кратна 1/2 длины волны изгибных колебаний, а высота боковой поверхности дополнительного полого усеченного конуса равна или кратна 1/4 длины изгибной волны и его высота равна или кратна 1/2 длины волны продольных колебаний, причем длина центрального стержн  равна или кратна 1/2 длины волны продольных колебаний. Сварочный инструмент совершает ультразвуковые колебани  в двух плоскост х: перпендикул рно и параллельно движению свариваемых материалов, что и обеспечивает повышение прочности сварного шва и его качества. 4 ил.The invention relates to the welding of plastics, in particular to devices for continuous ultrasonic welding. The goal is to increase the strength and quality of the weld. For this, the device is equipped with a magnetostrictive transducer 1, an elastic vibration transformer 2, a welded tool including a first hollow truncated cone 3 of bending vibrations and an additional hollow truncated cone 4 of longitudinal vibrations connected through a ring welding tip 5, the central rod element 6 of longitudinal vibrations that hollow truncated cones 3 and 4 along planes of smaller diameter 7 and 8. In this case, the height of the first truncated cone is equal to or a multiple of 4 of the length of the longitudinal wave, its height is equal to or a multiple of 1/2 the wavelength of the flexural vibrations, and the height of the side surface of the additional hollow truncated cone is equal to or a multiple of 1/4 of the flexural wavelength and its height is equal to or a multiple of 1/2 the wavelength of the longitudinal vibrations, and the length of the central rod is equal to or multiple of 1/2 wavelength of longitudinal oscillations. The welding tool performs ultrasonic oscillations in two planes: perpendicular and parallel to the movement of the materials to be welded, which ensures an increase in the strength of the weld and its quality. 4 il.
