Description

прикоснутс  с торцовой поверхностью опорной втулки 15. Поскольку между концами регулировочных шпилек 8 и опорной втулкой еще имеетс  зазор, а формующее кольцо подпружинено , подвижна  плита 7 имеет возможность перемещатьс , в результате чего дорн 1 сместитс  относительно формующего кольца 3. Это перемещение будет осуществл тьс  до тех пор, пока концы регулировочных шпилек не коснутс  поверхности опорной втулки. При этом перемещении уступ 2 дорна 1 сдеформирует нагретый участок раструба 17, как это показано на фиг. 4, образу  кольцевую заготовку на его конце. После охлаждени  сформованного участка раструба измен ют направление движени  подвижной плиты 7 и из раструба угольника извлекают дорн и формующее кольцо. Далее процесс формовани  повтор етс .contact with the end surface of the support sleeve 15. Since there is still a gap between the ends of the adjusting studs 8 and the support sleeve, and the forming ring is spring-loaded, the movable plate 7 is able to move, causing the mandrel 1 to move relative to the forming ring 3. This movement will take place before as long as the ends of the adjusting studs do not touch the surface of the support sleeve. With this movement, the ledge 2 of the mandrel 1 will deform the heated portion of the socket 17, as shown in FIG. 4, forming an annular blank at its end. After cooling the molded section of the bell, the direction of movement of the movable plate 7 is changed, and a mandrel and a forming ring are removed from the socket of the square. Next, the molding process is repeated.

Посредством регулировани  рассто ни  между шпильками 8 и опорной втулкой 15 можно формовать зиговки на раструбе различной формы (см. фиг. 5 и 6).By adjusting the distance between the studs 8 and the support sleeve 15, zigovki can be molded on a bell of various shapes (see Fig. 5 and 6).

Предмет изобретени Subject invention

Устройство дл  формовани  конца трубообразного издели  из термопластичного материала , содержащее дорн с подвижным формующим кольцом, отличающеес  тем, что, с целью упрощени  формовани  кольцевых зиговок , дорн на наружной поверхности имеет выступ, а формующее кольцо выполнено охватывающим с внутренней цилиндрической поверхностью двух различных диаметров с конической переходной поверхностью между ними.A device for forming the end of a tubular product made of a thermoplastic material, comprising a mandrel with a movable forming ring, characterized in that, in order to simplify the formation of annular zigovok, the mandrel on the outer surface has a protrusion, and the forming ring is made enveloping two cylindrical diameters transitional surface between them.
