Abstract
The present invention relates to the carcass belt combined method of three drum moulding micro truck semi-steel radial tires, comprises the steps：The carcass for posting sidewall rubber of forming is inserted on the moulding capsules of capsule shaping drum, the tyre bead portion on carcass one side is clamped on a chuck mechanism, belt is covered on carcass, 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；The tyre bead portion of carcass another side is clamped on another chuck mechanism；Moulding capsules inflate swell, strut carcass, make belt be close to carcass, coordinate the pressure roller of periphery to be compacted belt；After compacting terminates, moulding capsules are deflated, and take out the green tire of forming.Carcass and belt can be carried out efficient combination by the present invention, be the shaping provides convenient of mini truck semi-steel radial tire, reduce production cost.
Description
Technical field
The present invention relates to mini truck semi-steel radial tire manufacturing technology, specifically three drum moulding micros loads
The carcass belt combined method of weight automobile semi-steel radial tire, belongs to tire production manufacturing technology field.
Background technology
Radial has energy-conservation, the superiority such as safe and durable, is the main product of world's tire development.In order to full
Sufficient user and the needs of market development, improve product competitiveness, and each giant tyre company of the world puts into huge fund one after another, and exploitation is new to produce
Product, constantly release radial of new generation.
But for a large amount of mini trucks for existing at present（As heavy-duty tricycle）For, but it is not directed to its demand
The heavy load radial tire of design, its still can only use conventional tyre.Due to conventional tyre have resistance to load-carrying, resistance to puncture,
The advantages of shock resistance explosion, and tyre surface abrasion resistance is very poor, and during load transportation, easily accidents happened.
For drawbacks described above, our company devises a kind of mini truck semi-steel radial tire, and the tire product is adopted
With three drums（Carcass drum, band bundle drum and assembly drum）Shaping, manufactures carcass with carcass drum, manufactures belt with band bundle drum, so
Afterwards carcass and belt are combined with assembly drum.Described carcass can be using existing carcass drum and operator's legal system
Make, the making step of carcass is：Layer patch inner face glue（Tire bead cloth）, ground floor carcass ply, second layer carcass ply → positioning steel
Wire ring →（Rise drum）Anti-package, roll-in → on（Left and right）Tyre bead glue（Shoulder wedge）→ tyre bead rubber roll pressure → crimp head.The band bundle
Layer can be made using existing band bundle drum and operational method, and the making step of belt is：In the case of the drum that rises, layer is pasted respectively
Ground floor belt wirecord fabric, second layer belt wirecord fabric and crown → roll-in → crimp head.
Content of the invention
It is an object of the invention to overcoming the deficiencies in the prior art, providing a kind of three and rousing moulding micro truck
Carcass and belt effectively can be combined by the carcass belt combined method of semi-steel radial tire, the method, be
The shaping provides convenient of mini truck semi-steel radial tire, substantially reduces production cost.
According to the technical scheme that the present invention is provided：The carcass band bundle of three drum moulding micro truck semi-steel radial tires
Layer combined method, it is characterised in that：Carcass is combined by the method capsule shaping drum with belt, is comprised the steps：
（1）, the carcass for posting sidewall rubber of forming is inserted in capsule shaping drum moulding capsules on, carcass
Tyre bead portion is clamped on a chuck mechanism on capsule shaping drum, covers belt, in belt on carcass
Belt steel wire two ends extend to shoulder zone and are pressed on sidewall rubber outer edge, and the crown two ends in belt extend to tire
Take on region and envelope the overlapping part of belt steel wire and sidewall rubber；
（2）, the tyre bead portion of carcass another side is clamped to capsule shaping drum another chuck mechanism on；
（3）The moulding capsules inflation swell of capsule shaping drum, is inflated to pressure for 0.10-0.15Mpa, support in moulding capsules
Carcass is opened, makes belt be close to carcass, then coordinate the pressure roller of periphery that belt is compacted, platen pressure is 0.30-
0.45Mpa, compacting time are 10 ~ 15 seconds, it is desirable to be repeated 1 times；
（4）, compacting terminate after, moulding capsules deflate, moulding capsules drum return back to original state, take out the life of forming
Tire, carcass are terminated with belt combination process.
The present invention compared with prior art, has the advantage that：Carcass and belt can be carried out effectively by the present invention
Combination, is the shaping provides convenient of mini truck semi-steel radial tire, substantially reduces production cost.
Description of the drawings
Fig. 1 is the structural representation of the capsule shaping drum used by the present invention.
Fig. 2 is the relative position schematic diagram of carcass and belt.
Specific embodiment
With reference to concrete drawings and Examples, the invention will be further described.
As shown in the figure：The carcass belt of three drum moulding micro truck semi-steel radial tires is disclosed in embodiment
Combined method, the method are combined carcass 8 with belt 10 with capsule shaping drum, and the capsule shaping drum can be selected
Existing conventional equipment.
This gives a kind of capsule shaping drum, its structure is as shown in figure 1, main by center-pole 1, left capsule clamp-ring
3rd, right capsule clamp-ring 6 and moulding capsules 5 constitute, and the centre position of the center-pole 1 is provided with disk 4 of giving vent to anger, and the center-pole 1 is left
Be provided with inside half part disk 4 of giving vent to anger is axially extended to by 1 left end of center-pole enter return gas channel 1a；4 left side of disk of giving vent to anger sets
Left capsule clamp-ring 3 is put, 4 right side of disk of giving vent to anger arranges right capsule clamp-ring 6, and 5 left end edge of the moulding capsules is connected to left capsule clamping
On ring 3,5 right-hand member edge of moulding capsules is connected on right capsule clamp-ring 6；The left side of the left capsule clamp-ring 3 is provided with fixing chuck
Mechanism 2, the right side of the right capsule clamp-ring 6 are provided with movable chuck mechanism 7.
Roused using above-mentioned capsule shaping, carcass belt combined method specifically includes following steps：
（1）, the carcass 8 for posting sidewall rubber 9 of forming is inserted in capsule shaping drum moulding capsules 5 on, carcass 8 one
