Изобретение относитс  к сварке пласт масс, а именно к устройствам дл  шсвной ультразвуковой сварки. Известно устройство дл  шовной ультразвуковой сварки полимерных материалов содержащее вращающийс  многостержневой преобразователь с общей обмоткой возбуждени  и трансформатор колебаний в виде кольца l. Недостаток устройст ва заключаетс  в необходимости периодического его отключени  дл  охлаждй1и  элементов устройства, что снижает его производительность.. Наиболее близкое к изобретению уст ройство дл  шсжной ультразвуковой сварки полимерных материалов, содержащее выполненный из отдельных секторов дисковый инструмент, насаженной на тороидальный преобразователь и закрепленный в корпусе с помощью ;кольцевыхвыступов 2. Недостатком указанного устройства  вл етс  его нагрев в плоскост х контакта секторе дискового инструмента, колеб лющихс  с ультразвуксюой частотой, за счет трени  между ними, что ведет к перегреву поверхности материала, контактирующей с этими участками инструмента, и к снижению качества сварного соединени . Цель изобретени  - повышение качества сварки. Указанна  цель достигаетс  тем, что в устройстве дл  шовной ультразвуковой сварки полимерных материалов, содержащем выполненный из отдельных секторсж дисковый инструмент, насаженный на тороидальный преобра; ователь и закрепленный в корпусе с помощью коль.цё&Ь1х выступов . Секторы дискового инструмента расположены с зазором друг к другу, а тороидальный преобразсжатель выполнен из отдельных изолированных секций с индивидуальными обмотками возбуждени , число которых соответствует числу секторов дискового инструмента. Такое выполнение устройства обеспечивает качественную сварку-материалов.The invention relates to the welding of formation masses, namely to devices for advanced ultrasonic welding. A device for seam ultrasound welding of polymeric materials is known, which contains a rotating multi-rod transducer with a common field winding and an oscillation transformer in the form of a ring I. The drawback of the device is the need to periodically turn it off to cool the device elements, which reduces its performance. help; annular protrusions 2. The disadvantage of this device is its heating in the contact planes sector of the disk tool, Fluxing with ultrasound frequency, due to friction between them, which leads to overheating of the surface of the material in contact with these areas of the tool, and to a decrease in the quality of the welded joint. The purpose of the invention is to improve the quality of welding. This goal is achieved by the fact that in a device for seam ultrasonic welding of polymeric materials containing a disk tool made of individual sectors, mounted on a toroidal transform; The holder is fixed in the housing with the help of rings & b1x protrusions. The disk tool sectors are arranged with a gap to each other, and the toroidal converter is made of separate insulated sections with individual field windings, the number of which corresponds to the number of sectors of the disk tool. This embodiment of the device provides high-quality welding materials.
