Description
Дл гер метичного соединени трубопроводов из термопластичных материалов широко используетс разъемное фланцевое соединение, требующее отбортовки труб намного превышаюи.1:ей их наружный диаметр. Существующими способами формовани борта труб при помощи простейшего штампа с предварительным нагревом конца трубы не всегда удаетс получить отбортовку нужного диаметра вследствие влени складкообразовани и большого трени материала с пуансоном в процессе формовани . Кроме того, отсутствие стабильного температурного режима вызывает перенапр жени в материале и разностенность отбортовки .For hermetic joining of pipelines of thermoplastic materials, a split flange joint is widely used, requiring flanging of pipes much higher than 1: its outer diameter. The existing methods of forming the bead of pipes with the help of a simple die with preliminary heating of the end of the pipe do not always succeed in obtaining flanging of the desired diameter due to the occurrence of folding and great friction of the material with the punch during the molding process. In addition, the lack of a stable temperature regime causes overvoltages in the material and the difference in thickness of the flanging.
Предлагаемый способ позвол ет получить борт большого размера без по влени складок и строго выдержанный по толщине. Сущность способа заключаетс в том, что, с целью стабилизации температурного режима формовани и исключени складкообразовани , радиальные усили , приложенные на конец трубы, создаютс потоком гор чего сжатого воздуха, подаваемого через радиальные отверсти пуансона.The proposed method allows to obtain a bead of a large size without the appearance of folds and strictly sustained in thickness. The essence of the method lies in the fact that, in order to stabilize the molding temperature regime and eliminate folding, radial forces applied to the end of the pipe are created by a stream of hot compressed air supplied through the radial holes of the punch.
На чертеже изображено устройство дл отбортовки труб из термопластичных материалов, в разрезе. Отбортовываемый конец трубы / помещаетс в кольцо 2, фиксирующее степень отбортовки с таким расчетом , чтобы выступающа часть трубы соответствовала необходимом величине борта. Внутрь трубы вводитс пуансон 3, имеющий радиальные отверсти 4, через которые на отбортовываемую часть трубы направл етс поток гор чего сжатого воздуха. Подача воздхха в пуансон осуществл етс через боковой штуцер 5. Дл замера температуры воздуха в пуансоне в воздушный канал через специальный штуцер 6 вводитс ножка ртутного термометра 7. Стабильный те1мпературный реThe drawing shows a device for flanging tubes of thermoplastic materials, in section. The bead end of the pipe / is placed in the ring 2, which fixes the degree of flanging in such a way that the projecting part of the pipe corresponds to the required bead size. A punch 3 is inserted inside the pipe, having radial holes 4 through which a stream of hot compressed air is directed to the flanged part of the pipe. Air flow into the punch is carried out through the side fitting 5. To measure the temperature of the air in the plug, the leg of the mercury thermometer 7 is inserted into the air duct through a special fitting 6. Stable temperature ratio
