Цель изобретени  - расширение технологических возможностей, что позвол ет производить сварку термопластов с произ- вольн1 ми значени ми в зкости.The purpose of the invention is the expansion of technological capabilities, which allows welding thermoplastics with arbitrary viscosity values.

На чертеже представлена схема устройства .The drawing shows a diagram of the device.

Устройство дл  сварки разнотипных термопластов состоит лз источника 1 питани , нагревател  2, включающего теплоносители 3 и 4, электронагревательные элементы 5 и 6, разделенные теплоизолирующей пластиной 7, в электрические цепи электронагревательных элементов включены терморегул торы 8 и 9, подключенные, как и датчики уровн  первичного грата 10 и 11, к блоку 12 сравнени  и механизма 13 дл  закреплени  и сжати .A device for welding different types of thermoplastics consists of a power supply source 1, a heater 2 including heat carriers 3 and 4, electric heating elements 5 and 6, separated by a heat insulating plate 7, and electric heating elements 8 and 9 are connected to the electrical heating elements. grata 10 and 11, to comparison unit 12 and mechanism 13 for fastening and squeezing.

Устройство работает следующим образом .The device works as follows.

Разнотипные трубы 14 и 15 закрепл ютс  с помощью механизма 13 закреплени  и сжати . В зазор между свариваемыми трубами вставл етс  нагреватель 2, при этом теплоносители 4 и 3 прижимаютс  к торцам свариваемых труб 14 и 15. В начальный момент нагрева теплоносител  3 и 4 имеют одинаковую температуру, так как под воздействием одинаковых токов в электронагревательных элементах 5 и 6 выдел етс  одинаковое количество тепла. На начальном этапе нагрева вследствие выталкивани  расплавленного материала формируетс  первичный грат 16 и 17. Высота первичного грата, завис ща  от в зкости материала трубы, регистрируетс  с помощью датчиков уровн  грата 10 и 11. Электрический сигнал от этих датчиков подаетс  в блок 12 сравнени , который вырабатывает и подает сигнал на терморегул торы 8 и 9,The various types of pipes 14 and 15 are fixed by means of a fastening and squeezing mechanism 13. A heater 2 is inserted into the gap between the welded pipes, while the heat carriers 4 and 3 are pressed to the ends of the welded pipes 14 and 15. At the initial moment of heating the heat carrier 3 and 4 have the same temperature, because under the influence of the same currents in the electric heating elements 5 and 6, the same amount of heat. At the initial stage of heating, a primary burr 16 and 17 is formed due to the ejection of the molten material. The height of the primary bur, depending on the viscosity of the pipe material, is recorded using grab level sensors 10 and 11. The electrical signal from these sensors is fed to comparison unit 12, which produces and sends a signal to the thermostats 8 and 9,

уменьшающие силу тока в том электронагревательном элементе, со стороны которого высота грата больше, и, наоборот, увеличивает силу тока в электронагревательномreduce the current in the electric heating element, from the side of which the height of grata is greater, and, conversely, increases the current in the electric heating

элементе со стороны, где высота грата первичного меньше.element from the side where the height of the primary grata is less.

Указанное увеличение и уменьшение тока автоматически регулируетс  до полного выравнивани  высот первичного грата. Одинакова  величина первичного грата 16 и 17, достигаема  при различных температурах нагрева, свидетельствует о том, что достигнуто одинаковое значение в зкости разнотипных материалов. Затем осуществл етс  прогрев труб 14 и 15 при установленныхThis increase and decrease in current is automatically adjusted to fully equalize the heights of the primary flash. The same value of primary grata 16 and 17, achieved at different heating temperatures, indicates that the same viscosity value of different types of materials is achieved. Then the pipes 14 and 15 are heated with the installed

различных температурах. В результате за одинаковое врем  нагрева проплавленные участки разнотипных свариваемых труб имеют одинаковую в зкость, что требуетс  дл  обеспечени  высокого качества сварного соединени . После окончани  процесса нагрева нагреватель 2 удал етс  из зазора, затем свариваемые трубы 14 и 15 с помощью механизма 13 закреплени  и сжати  труб с усилием прижимаютс  друг к другу при этом происходит сварка труб.different temperatures. As a result, at the same heating time, the melted parts of different types of pipes being welded have the same viscosity, which is required to ensure high quality of the welded joint. After the end of the heating process, the heater 2 is removed from the gap, then the pipes 14 and 15 to be welded are pressed against each other with the help of a clamping and pressing mechanism 13 by welding the pipes.
