Изобретение относитс к оборудованию дл шинной промышленности , оно предназначено дл сборки большегрузных и авиационных покрышек.The invention relates to equipment for the tire industry, it is intended for the assembly of heavy and aircraft tires.

Известны барабаны дл сборки покрышек пневматических шин.Known drums for assembling tires pneumatic tires.

Указанный барабан содержит радиально раздвижные сектора, механизм разведени секторов, выполненный в виде рычагов, шарнирно св занных с секторами и с подвижными вдоль ступицы барабана посредством привода кольцевыми ползунами, заплечики, шарнирно св занные с секторами посредством регулируемых т г и заплечики секторов, располагающихс снаружи сложенного барабана.Said drum contains radially extending sectors, a sector dilution mechanism made in the form of levers hinged to sectors and moving along a drum hub by driving ring sliders, shoulders hinged to sectors by means of adjustable t r and sectors shoulders outside of folded the drum.

Однако в известном барабане при его складывании сектора совершают радиальное и осевое перемещение, что увеличивает габариты станка, а механизм убирани заплечиков внутрь барабана выполнен таким образом, что увеличивает габариты барабана в осевом направлении, и, следовательно, ограничивает область е.го применени However, in a known drum, when the sector is folded, they make radial and axial movement, which increases the dimensions of the machine, and the mechanism for tucking the shoulders inside the drum is designed in such a way that it increases the dimensions of the drum in the axial direction, and therefore limits its application area.

Известен и другой барабан дл сборки покрышек пневматических шин, содержащий радиально раздвижные сектора , механизм разведени секторов, выполненный в виде рычагов, шарнирно соединенных с секторами и-с подвижными вдоль ступицы барабана посредством привода кольцевыми ползунами , установленными концентрично относительно один другого и относительно ступицы и св занными между собой посредством фиксаторов,заплечики , шарнирно соединенные с секторами Another drum for tire assembling of pneumatic tires is also known, containing radially extending sectors, a sector dilution mechanism made in the form of levers pivotally connected to the sectors and moving along the drum hub by means of an actuator by annular sliders mounted concentrically relative to one another and relative to the hub and st interconnected by means of clamps, shoulders pivotally connected to sectors

5 посредством регулируемых т г, св занных с рычагами механизма разведени посредством шарнирно прикрепленного к ним промежуточного звена, снабженного копирным пальцем, 5 by means of adjustable t g connected with the levers of the mechanism of dilution by means of a pivotally attached intermediate link equipped with a copying finger,

Claims

0 interacting with the shaped groove, which is made on the respective sectors, and the shoulders of the sectors located outside the folded drum. The last of the above reels is closer to the described invention. The disadvantage of this drum is that the radial stroke of the sectors is limited by the radial stroke of the shoulders, so the drum has a small coefficient of folding, which reduces the range of collected tires. The purpose of the invention is to expand the operational capabilities of the drum. This goal is achieved in that the shoulders of the sectors located outside the folded drum are pivotally connected to the lever of the sector dilution mechanism by means of a spring-loaded slot with a groove and are provided with an abutment, an interacting groove. FIG. 1 shows a longitudinal section of the drum in the open position; in fig. 2 is a longitudinal section of the drum in the folded position. The drum contains radially section. moving sectors 1 and 2. Sectors 2 are spherically connected to the shoulders 3 by means of adjustable legs i. The shoulders 5 of the sectors 1 located outside the folded drum are spherically connected to the lever 6 of the sector dilution mechanism 1 By means of a spring-loaded pull 7 with a groove 8 and provided with an abutment 9 interacting with the groove. The breeding mechanism of sectors 1 and is made in the form of levers 6 and 10, are associated with sectors and sub-axles along the hub 11 of the drive shaft 12 of the drum by driving ring 13 and k, which are mounted concentrically relative to each other and relative to the hub 11 and connected among themselves by means of clamps 15. The shaft 12 is rigidly connected with the screw 16 located inside the hub 11, having a right and left screw thread. On the screw 16, the nuts 17 are connected to the sliders 14; Adjustable sleeves k of the shoulders 3 are connected to the levers 10 by means of an intermediate link 18 hingedly attached to them, equipped with a copying finger interacting with the figured groove 19, which is made on sectors

2. The stop 9 is connected to the spring 20. The device operates as follows. The hub 11 is braked and the shaft 12 rotates the spindle 16 by moving the nuts 17, the slide blocks and the levers 10, while the sectors 2 move radially and the shoulders 3 retract into the interior of the drum. After stopping the sliders k into the sliders 13 by the shoulders 3 through links 18 and ti 4, they completely retract the inside of the drum, and sector 1 under the action of the levers 6 connected to the sliders 13 also move radially to the drum axis, thus removing the shoulders 5 due to actions J. After removing the shoulders 5 into the inside of the drum with further movement of the levers 6, the stops 9 of the shoulders 5 slip through the grooves 8. Tr) The running stroke values and movement order of the sliders 13 and 14 are provided by the action of the latches 15. In folded The position of Fig. 2) the drum has a diameter of a circumscribed circle, smaller than the diameter of the assembled tire along the side, so that the tire is easily removed from the drum. Pacing of the drum occurs, in order, in reverse order of folding. In this drum, the folding of shoulders 3 and 5 inside the drum occurs, which eliminates the deformation of the beads of the assembled tires and allows the use of a drum for assembling tires with a sealing layer on the inner surface. The mechanism for removing the shoulders 3 and 5 of sectors 1 and 2, which are in the folded drum from the outside, has small dimensions, is kinematically connected with the driving lever of the sector mechanism, which gives a large folding factor, expands the range of assembled tires and provides automatic removal of the shoulders. DETAILED DESCRIPTION OF THE INVENTION A drum for assembling tires of pneumatic tires containing 1 (radially extending sectors, a sector dilution mechanism made in the form of levers hinged to sectors and moving along a drum hub by means of an actuator by annular sliders mounted concentrically relative to one another and relative to the hub and interconnected by means of clamps, shoulders pivotally connected to the sectors by means of adjustable tg, connected to the levers of the dilution mechanism through a jointly attached to them interline comic link, equipped with a copier finger, which is made on the respective sectors, and shoulders of sectors located outside the folded drum, characterized in that, in order to expand the operational capabilities of the Aban bar, the shoulders of sectors located outside the folded drum, pivotally connected with the lever of the sector dilution mechanism by means of a spring-loaded T gi with a groove and provided with an abutment interacting with the groove.
