Description

I .Изобретение относитс к оборудованию шинной промьп ленности и предназначено дл обработки борта покрышек пневматических шин, в частности дл обработки борта покрышек на полуплоском барабане.I. The invention relates to tire industry equipment and is intended for the treatment of a tire bead of pneumatic tires, in particular for the treatment of a tire bead on a semi-flat drum.

Известен механизм обработки борта к станку дл сборки покрышек пневматических шин, включающий сиотему обжимньк и заворотных рычагов с приводе их перемещени .A known mechanism for processing a bead to a machine for assembling tires of pneumatic tires includes a cell press and turning levers with a drive for moving them.

Известный механизм выполн ет холостую операцию по подводу, рычагов дл заворота и обжима слоев корда, что сни жает производительность сборки покрышек . Кроме того, конструкци указанных рычагов не позвол ет обрабатывать борт докрьвиек при сборке их на полуплоском барабане с большой величиной заворота слоев корда на корону барабана.The known mechanism performs the idle operation on the supply, levers for turning and crimping the cord layers, which reduces the productivity of tire assembly. In addition, the design of these levers does not allow processing of the side of the arms when assembling them on a semi-flat drum with a large amount of wrapping of the cord layers on the crown of the drum.

С целью упрсадени конструкции механизма при сборке покрышек на полуплоских барабанах в предлагаемом изобретении заворотные рачаги выполнены в виде секторов, объединенных кольцевой спиральной пружиной и смонтированных на штангах, установленных в направл ющих корп-уса и кинематически св занных посредством рычагов подъема штанг, подIn order to reinforce the design of the mechanism when assembling tires on semi-flat drums in the present invention, the turn bars are made in the form of sectors united by an annular helical spring mounted on rods installed in body-rail guides and kinematically connected by means of lifting rods under

На фиг. 1 показан предлагаемый механизм в мс лент посадки крыла, продольный разрез; на фиг. 2 - то же, в момент наложени слоев корда на барабан сборочного станка; на фиг. 3 то же, в межент перемещени обжимных рычагов дл обжати слоев корда по заплечику и посадки крыла; на фиг. 5 то же, в мсмйент заворота корда на корону сборочного барабана сектораи 1и вспомогательного барабана.FIG. 1 shows the proposed mechanism in ms of landing strips, longitudinal section; in fig. 2 - the same, at the moment of laying layers of cord on the drum of the assembly machine; in fig. 3 the same, in the internent movement of the crimp levers to compress the layers of the cord over the shoulder and fit the wing; in fig. 5 the same, in terms of turning the cord on the crown of the assembly drum of sector 1 and auxiliary drum.

Механизм состоит из вспомогательного барабана I, образованного секторами , соединенными между собой по внутреннему диаметру кольцевой пружиной 2. Сектора укреплены на штангах 3 которые в направл ющих 4, жестко соединенных между собой v с корпусом 5 механизма, установленного и зафиксированного на валу 6 сборочного станка с возможностью вращени Вместе с ним.The mechanism consists of an auxiliary drum I formed by sectors interconnected by an internal spring with an annular spring 2. The sectors are fixed on rods 3 which are in guides 4 rigidly interconnected v with the mechanism housing 5 mounted on the shaft 6 of the assembly machine possibility of rotation along with it.

Claims

In the housing 5, the arms 7 for lifting the rods 3 are hinged, which are kinematically connected through the movable disk 8 and the rollers 9 to the pistons 10, 11 of the pneumatic cylinder 12, having adjustable stops 13,14. The crimping levers 15 are mounted over the rectillator drum and pivotally connected with the levers 16 rotating around the axes 17 fixed in the guides of the housing 19, the free-mounted shaft 6. of the assembly machine. The free ends of the levers 16 are connected 20 by the action of which the levers 16 hold the crimp levers 15 with the template 21 retracted in the extreme upper position. The mechanism works as follows. Moving up to the stop 13, the piston 11 through the rollers 9, the movable disk 8 and the lifting arms 7 of the rods 3 transmit the movement to the sectors of the drum 1, which, being moved radially apart, form an auxiliary drum with a diameter equal to the diameter of the machine’s assembly drum. The template 21 and the levers 15 crimped out the deck beyond the sector drum (Fig. 2). This position corresponds to the position of the mechanism during the operation of laying layers of cord on the assembly drum. At the end of the operation (and the imposition of the cord cord, the crimping levers 15 are pulled over the cord layers located on the Sector drum 1 to crimp them (Fig. 3) .. When the wing is seated, the pattern 21 is on the crimp levers 15, through them it acts the sectors of the drum 1, compress them, and then through the levers 7, lift the rods 3, the sliding disk 8 and the rollers 9 onto the piston 10, retract it and the piston II to their original position. Move the crimp levers and the sector drum to the assembly drum , compress the layers of the cord and the wing over the shoulder of the assembly drum (FIG. 4). After landing the wing and crimping the layers of the cord, the levers 15 crimping and the template 21 are brought out of the limits of the sector drum 1; Then move the piston 10 to the stop 14 through the rollers 9, the movable disk 8 and the levers 7 for lifting the rods 3, the layers of the drum 1 wrap the layers of the cord onto the Koporiy assembly drum and Further, above the sector drum 1 on the assembly drum, crimping of the wrapped cord layers is performed by the drum sectors, which in this operation act as crimping levers. . The invention of the processing mechanism of the bead to the machine for assembling tires pneumatic tires, including a template, a system of squeezing and turn-up levers with a drive Hk of displacement, so that, in order to simplify the design of the mechanism during assembly pokrylak on half-flat 6apa6kHax, turn-ups, chagi made in the form of sectors, united by an annular spiral spring and mounted on rods, set in the guiding housings and kinematically connected by means of lifting rods, rolling disk and rollers with rivodom movement levers.
