According to the mechanical building drum with the auxiliary turn-up bladder, a layer of bladder is coated on the outer circumference surface of each of two side drums on the original mechanical building drum respectively, the bladder is used as a buffer layer, and a sidewall can be indirectly rolled through the bladder in the turn-up process of the sidewall, so that the indentation caused by the direct rolling of a turn-up roller on the side wall of the tire is avoided, and the quality and the performance index of a tire base can be improved.
Description
Technical field
The utility model belongs to the rubber manufacturing machinery technical field, particularly relates to a kind of mechanical type assembly drum with auxiliary reverse-wrapped capsule.
Background technology
Assembly drum is one of building block of most critical in the tyre building machine, is installed on the main shaft of assembly drum cabinet, is the main actuating unit of finishing the moulding process such as the anti-package of green tyre and roll extrusion, and its structure directly affects the quality of tire.In full steel wire heavy load radial-ply tyre forming process, the anti-package effect of tire mold side is the key factor that determines the tyre performance index, thereby assembly drum has been proposed stricter requirement.
At present mainly be divided into two kinds of capsule-type and mechanical types for the production of the assembly drum of full steel wire heavy load radial-ply tyre.Wherein the capsule-type assembly drum is in drum body circumferential surface two-layer capsule to be installed, from outward appearance to inner essence be respectively reverse-wrapped capsule and boosting capsule, utilize the direct anti-package of reverse-wrapped capsule sidewall, the auxiliary anti-package action of boosting capsule, two capsules all be by source of the gas constantly air feed make its expansion reach the position that anti-package needs.The advantage of capsule anti-package is that the extrusion ratio to the sidewall is more even in turn-up process, the quality of tire base is good, but shortcoming is capsule belongs to expendable part, have certain life cycle and life-span, in case therefore service time long will be on the mass formation impact of tire base, at this moment just must change, the result changes capsule frequently just becomes the maximum drawback of capsule shaping drum.
The mechanical type assembly drum is at drum body circumferential surface the counter-wrapping rod of some to be installed, and an end of counter-wrapping rod is fixed on the cylinder that can repeatedly move, and the other end can open and shrink under the effect of cylinder, thereby reaches the purpose on anti-package sidewall.Machinery anti-package preferentially be to change continually counter-wrapping rod, improved production efficiency, reduced cost, but shortcoming is because counter-wrapping rod is the effect that reaches contraction by being installed in glue ring in the groove of bulging surface, so in counter-wrapping rod carries out the process of anti-package, can be subject to the reaction force that the glue circulating application adds, will cause to a certain degree impression to the surface on sidewall at the position of anti-package roller process so, the sizing material between the steel wire is pushed, thereby affect the quality of tire base.
Therefore, the assembly drum of two kinds of structures has pluses and minuses separately, and is relative, so have to be solved.
Summary of the invention
