The turning down and turning up device is a purely mechanical turning down and turning up device, avoids a capsule turning down or turning up device in the prior turning down and turning up device, has a simple structure, and reduces the cost.
Description
(1) technical field:
Patent of the present invention relates to a kind of tyre building machine, is specially the tyre building machine turn-up and turn-down device.
(2) technical background:
The turn-up and turn-down device of tyre building machine is the tyre building machine core component, and traditional turn-up and turn-down is equipped with capsule and just wraps, the finger-type anti-package; Finger-type is just wrapped, the capsule anti-package; Capsule just wraps, several forms such as capsule anti-package.Traditional turn-up and turn-down device can reach the following finer wire anti-package of R33 power, but counter-wrapping rod will extend, and capsule is consumable accessory, often change the cost height.But along with the specification of tire is done greatly to more than the R33, overstriking along with steel wire diameter, use traditional turn-up and turn-down device will reach enough anti-package power, capsule then will be done very greatly, or do counter-wrapping rod very longly, and capsule is done very greatly, and optical cement capsule die sinking cost is just very high, capsule or consumable accessory, expense is just bigger like this.We realize just bag and anti-package to wirecord fabric by the design turn-up and turn-down device with the finger-type bar, overcome the high shortcoming of expense of the positive anti-package initiation of capsule, and are simple to operate, easy to maintenance.
(3) patent of invention content:
At the weak point of above-mentioned traditional turn-up and turn-down device, the invention provides and a kind ofly realize wirecord fabric is just being wrapped tyre building machine turn-up and turn-down device with anti-package with mechanical system.
Can realize the tyre building machine turn-up and turn-down device of above-mentioned purpose, comprise the finger-type bar opening and closing mechanism that coaxial package can just wrap wirecord fabric on the drum shaft of assembly drum both sides, at least, different is: comprise that also the above-mentioned finger-type bar opening and closing of cooperation mechanism carries out the anti-package device of anti-package to wirecord fabric, the anti-package device comprises anti-package draw ring device and is arranged at the harmomegathus mechanism that can radially expand and shrink on the anti-package draw ring device that anti-package draw ring device can be installed on the drum shaft of assembly drum port with moving axially.After finger-type bar opening and closing mechanism finishes the work of just undertaking to perform work within a time limit and according to specifications, tyre bead enters wirecord fabric by just wrapping reducing, the harmomegathus mechanism that the anti-package draw ring puts radially expands the steel ring triangle glue joint portion of compacting wirecord fabric and tyre bead, the anti-package wirecord fabric so that the finger-type bar of finger-type bar opening and closing mechanism can be come in is opened in the wirecord fabric expansion that anti-package draw ring assembly axis outwards moves behind the Jiang Zhengbao.Owing to be fitted with the anti-package device, make above-mentioned finger-type bar opening and closing mechanism carry out anti-package to wirecord fabric, make tyre building machine turn-up and turn-down device of the present invention become the Purely mechanical structure.
