Abstract
The invention relates to a tire casing belt combing method of a tri-drum formed minitype truck semisteel radial ply tire. The method comprises the following steps: a well-formed tire casing on which sidewall rubber is well adhered is sleeved by with a formed capsule of a capsule forming drum, a tire bead part on one side of the tire casing is clamped and fixed on a chuck mechanism, the tire casing is sleeved by a belt layer, the two ends of the belt layer wire in the belt layer extend to a tire shoulder region and press the outer side edges of the sidewall rubber, and the two ends of the crown rubber in the belt layer extend to the shoulder region and cover the overlapped part of the belt layer wire and the sidewall rubber; the tire bead part on the other side edge of the tire casing is clamped and fixed on another chuck mechanism; the formed capsule is inflated and swelled, the tire casing is expanded, the belt layer is enabled to be tightly adhered to the tire casing, and with the matching of peripheral compression rollers, the belt layer is compacted; after the compacting is finished, the formed capsule is deflated, and a well formed green tire is taken out. According to the method provided by the invention, the tire casing and the belt layer are effectively combined, convenience is provided for the formation of the tri-drum formed minitype truck semisteel radial ply tire, and the production cost is lowered.
Description
Technical field
The present invention relates to mini truck semi-steel radial tire manufacturing technology, specifically the carcass belt combined method of three drum moulding micro truck semi-steel radial tires, belongs to tire production manufacturing technology field.
Background technology
Radial has the superiority such as energy-conservation, safe and durable, is the main product of world's tire development.In order to meet the needs of user and market development, improve product competitiveness, each giant tyre company of the world drops into huge fund one after another, develops new product, and constantly releases radial of new generation.
But for the mini truck (as heavy-duty tricycle) of a large amount of existence at present, but not for the heavy load radial tire of its Demand Design, it still can only use conventional tyre.Do not have the advantages such as resistance to load-carrying, resistance to puncture, shock resistance explosion due to conventional tyre, and tyre surface abrasion resistance is very poor, in load transportation process, easily accidents happened.
For above-mentioned defect, our company devises a kind of mini truck semi-steel radial tire, this tire product adopts three drums (carcass drum, band bundle drum and assembly drum) shaping, carcass is manufactured by carcass drum, manufacture belt with band bundle drum, then carcass and belt assembly drum are combined.Described carcass can utilize existing carcass drum and operational method to make, and the making step of carcass is: laminating inner face glue (tire bead cloth), ground floor carcass ply, second layer carcass ply → location steel wire ring → (rise drum) anti-package, roll-in → upper (left and right) tyre bead glue (shoulder wedge) → tyre bead rubber roll pressure → crimp head.Described belt can utilize existing band bundle drum and operational method to make, and the making step of belt is: in difference laminating ground floor belt wirecord fabric, second layer belt wirecord fabric and the crown → roll-in → crimp head in bulging situation of rising.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of carcass belt combined method of three drum moulding micro truck semi-steel radial tires is provided, carcass and belt can effectively combine by the method, for the shaping of mini truck semi-steel radial tire is provided convenience, greatly reduce production cost.
According to technical scheme provided by the invention: the carcass belt combined method of three drum moulding micro truck semi-steel radial tires, is characterized in that: carcass and belt combine by the method capsule shaping drum, comprise the steps:
(1), the carcass posting sidewall rubber of forming is inserted on the moulding capsules of capsule shaping drum, carcass tyre bead portion is on one side clamped on a chuck mechanism on capsule shaping drum, belt on carcass overlaps, belt steel wire two ends in belt extend to shoulder zone and are pressed on sidewall rubber outer edge, and the crown two ends in belt extend to shoulder zone and envelope the overlapping part of belt steel wire and sidewall rubber;
(2), the tyre bead portion of carcass another side is clamped on another chuck mechanism of capsule shaping drum;
(3) the moulding capsules inflation swell of capsule shaping drum, being inflated to pressure in moulding capsules is 0.10-0.15Mpa, strut carcass, belt is made to be close to carcass, then coordinate peripheral pressure roller that belt is carried out compacting, platen pressure is 0.30-0.45Mpa, and the compacting time is 10 ~ 15 seconds, requires repetition 1 time;
(4), after compacting terminates, moulding capsules is exitted, and moulding capsules drum returns back to original state, and take out the green tire of forming, carcass and belt combination process terminate.
compared with prior art, tool has the following advantages in the present invention:carcass and belt can effectively combine by the present invention, for the shaping of mini truck semi-steel radial tire is provided convenience, greatly reduce production cost.
