Description
(54) СВАРОЧНАЯ ГОЛОВКА ДЛЯ ТЕРМОПЛАСТОВ(54) WELDING HEAD FOR THERMOPLASTS
Газ-теплоноситель через патрубки 8 поступает в камеры 6, откуда по патрубкам 9 переходит в калориферы 1, где нагреваетс и поступает в распределительные коробки 3, откуда через отверсти 4 - в рабочие полости 5. На мембраны 7 со стороны камер 6 оказывает давление поступающий в головку холодный лоноситель. С внешней стороны на них действует давление отработанного газа-теплоносител , выход щего из рабочих полостей 5. В результате между мембранами и поверхностью свариваемого материала по периметру рабочей полости создаетс зазор, величина и аэродинамическое сопротивление которого определ етс соотношением давлений по обеим сторонам мембран. Соотношение давлений регулируетс дроссельными заслонками 10.The heat transfer gas through the nozzles 8 enters the chambers 6, from where it goes through the nozzles 9 to the heaters 1, where it heats up and enters the junction boxes 3, from where it goes through the openings 4 to the working cavities 5. On the membranes 7 from the side of the chambers 6 head cold bearer. From the outside, they are influenced by the pressure of the exhaust gas-coolant exiting the working cavities 5. As a result, a gap is created between the membranes and the surface of the material being welded around the perimeter of the working cavity, the size and aerodynamic resistance of which is determined by the ratio of pressures on both sides of the membranes. The pressure ratio is controlled by the throttle valves 10.
В рабочих полост х 5 газ-теплоноситель разогревает место сварки, опрессовка тва происходит в результате прижима свариваемых кромок материала статическим давлением , возникающим в рабочих полост х головки по обе стороны шва вследствие аэродинамического сопротивлени зазора, образованного мембранами и поверхностью сва риваемого материала.In the working cavities 5, the heat-transfer gas heats up the welding site, the crimping process occurs as a result of pressing the welded edges of the material with static pressure arising in the working cavities of the head on both sides of the seam due to the aerodynamic resistance of the gap formed by the membranes and the surface of the welded material.
Благодар выполнению распределительных коробок с расположеннь;мн по периметру камерами с упругими мембранами со стороны свариваемого материала и патрубками дл ввода газа-теплоносител и соединени ихDue to the implementation of distribution boxes with located; around the perimeter of the chambers with elastic membranes on the side of the material to be welded and nozzles to enter the heat transfer gas and connect them
с калориферами, обеспечиваетс равномерный прижим при сварке армированного и тисненого материала. К тому же исключаетс возможность прилипани материала к сварочной головке, так как при опрессовке шва отсутствует контакт между головкой и свариваемым материалом.with heaters, a uniform clamping is provided when welding reinforced and embossed material. In addition, the possibility of material sticking to the welding head is excluded, since there is no contact between the head and the material to be welded when pressing the seam.
