Description

(54) БАРАБАН ДЛЯ СБОРКИ И ФОРМОВАНИЯ ПОКРБНиЕК ПНЕВМАТИЧЕСКИХ ШИН(54) DRUM FOR ASSEMBLING AND FORMING PAIRING PNEUMATIC TIRES

мой покрышки и приводы дл  возвратно поступательного перемещени  кольцевых ползунов , согласно изобретению снабжен боковыми секторами, выполненными с чередующими выступами и впадинами и шарнирно соединенными с наружной съемной профильной частью, выполненной также с чередующимис  выступами и впадинами, взаимодействующими с соответствующими выступами и впадинами боковых секторов.My tires and actuators for reciprocally moving annular sliders according to the invention are provided with side sectors made with alternating protrusions and depressions and hinged to an external removable profile part, also made with alternating protrusions and depressions interacting with corresponding protrusions and valleys of the side sectors.

На фиг. 1 показан предлагаемый барабан , разрез; на фиг. 2 - система т г.FIG. 1 shows the proposed drum section; in fig. 2 - t system

Барабан содержит радиально раздвижные секторы с наружной эластичной оболочкой 1, каждый из которых выполнен в виде основной части 2 с центральным пазом «а и симметрично расположенными относительно центрального паза боковыми поперечными пазами «б и наружной съемной профильной части 3, установленной на основной 2 и св занной с эластичной оболочкой 1, систему перекрещивающихс  т г 4, св занную посредством установленного в центральном пазу«а копирного пальца 5 и установленных в боковых поперечных пазах «б осей 6 с основной частью секторов и с подвижными вдоль приводного вала 7 каретками 8, смонтированные на ступице 9 барабана с обоих его торцов системы кольцевых концентричных ползунов 10 с закрепленными на них системами рычагов 11 дл  удержани  бортов собираемой покрышки и приводы дл  возвратно-поступательного перемещени  кольцевых ползунов 10.The drum contains radially extending sectors with an outer elastic shell 1, each of which is made as a main part 2 with a central groove "a" and laterally transverse grooves "symmetrically located with respect to the central groove" b "and an external removable profile part 3 installed on the main 2 and connected with elastic sheath 1, a system of intersecting t g 4, connected by means of a copier 5 installed in the central groove "a" and fixed in the lateral transverse grooves "6 axes 6" with the main part of the sectors and movable carriages 8 along the drive shaft 7 mounted on the drum hub 9 at both its ends with a system of annular concentric sliders 10 with systems of levers 11 fixed to them for holding the sides of the assembled tire and drives for reciprocating movement of the ring sliders 10.

Каретки 8 установлены на валу 7 посредством резьбовых гаек 12. Вал 7 имеет левую и правую нарезки.The carriage 8 is mounted on the shaft 7 by means of threaded nuts 12. The shaft 7 has left and right cutting.

Барабан снабжен боковыми секторами 13, выполненными с чередующимис  выступами «в и впадинами «г и щарнирно св занными ос ми 14 с наружной съемной профильной частью 3, .выполненной также с чередующимис  выступами «д и впадинами «е, взаимодействующими с соответствующими выступами «в и впадинами «г боковых секторов 13.The drum is provided with side sectors 13, made with alternating protrusions "in and depressions" g and hingedly connected axes 14 with an external removable profile part 3, made also with alternating protrusions "g and depressions" e, interacting with corresponding protrusions "in and valleys "g side sectors 13.

Барабан работает следующим образом.The drum works as follows.

Барабан находитс  в исходном положении (см. фиг. 1 нижн   часть чертежа). В полости кольцевых ползунов 10 подают рабочий агент в результате этого система рычагов занимает положение, изображенное на верхней части фиг. 1.The drum is in the initial position (see Fig. 1 lower part of the drawing). In the cavity of the annular sliders 10, the working agent is supplied. As a result, the leverage system occupies the position depicted in the upper part of FIG. one.

Одновременно вращаетс  вал 7 и с помощью перекрещивающихс  т г 4 сектора барабана раскрываютс . Эластична  оболочка 1 раст гиваетс  и образует цилиндрическую поверхность. Сектора раскрываютс  до тех пор, пока боковые секторы 13 не будут примыкать к кромкам основной части 2 секторов. В этот момент эластична  оболочка 1 принимает форму наружной профильной части 3 секторов, котора  в точности соответствует профилю, который требуетс  придать внутренней поверхности изготавливаемой покрышки.At the same time, the shaft 7 rotates and with the help of the crossing t g the 4 sectors of the drum open. The elastic sheath 1 is stretched and forms a cylindrical surface. The sectors open until the side sectors 13 adjoin the edges of the main part 2 of the sectors. At this moment, the elastic shell 1 takes the form of the outer profile part 3 of the sectors, which exactly corresponds to the profile that is required to impart to the inner surface of the tire being manufactured.

Наличие выступов «в и «д и впадин «г и «е обеспечивает получение однородной поверхности барабана, так как в исходном положении барабана они располагаютс  внахлестку, а при рабочем положении - выступы вход т в соответствующие впадины , что обеспечивает получение однородной поверхности дл  собираемой покрышки.The presence of protrusions " d and " d and valleys " g and " e provides a uniform drum surface, since in the initial position of the drum they are overlapped, and when in working position, the protrusions enter into corresponding cavities, which ensures a uniform surface .

Далее осуществл етс  формование собираемой покрышки и завершение операции сборки. Затем- цикл сборки повтор етс .Next, the collected tire is molded and the assembly operation is completed. Then the assembly cycle repeats.
