Description
Technical field
The present invention relates to a kind of methods that steel wire cap strip " S " type spiral winding prepares all-steel radial tyre, belong to wheel
Tire manufacturing technology field.
Background technique
In all-steel radial tyre driving process, when road hazards, travel speed are very fast, pot hole, height are encountered
Low uneven or when having sharp object puncture tire, the impact force that wheel crown part is locally subject to is larger, and tyre surface is caused to be wounded by stabbing, pierce through,
Even belt structure is destroyed, and such as impaired tire continues to use, and causes the dangerous destructions modes such as wheel crown is quick-fried, top is quick-fried.
In existing all-steel radial tyre structure, each belt of severing has a respective angles, and steel wire cap strip angle
It is 0 °, the belt coefficient of strain of steel wire cap strip coefficient of strain and severing is inconsistent, and belt and steel wire cap strip uphold and be
Number mismatches, and steel wire cap strip is too tight by belt hoop, and belt and steel wire string of a hat interlayer generate internal stress, tire used process
In there are hidden danger.
Summary of the invention
It is an object of the invention to: a kind of steel wire cap strip " S " type spiral winding is provided and prepares all-steel radial tyre
Method, to solve the problems, such as that belt and steel wire cap strip coefficient of strain are unmatched, by the steel wire band of winding to carcass
And belt forms hoop effect, inhibits after tyre inflating shoulder to be radially expanded, circumferential deformation quantity, reduce the creep of crown center,
The mutual stress of banding interlayer is reduced, safety, belt service life and the Life of Tyre during tire used are greatly improved,
To overcome deficiency in the prior art.
To solve the above problems, such a steel wire cap strip " S " type spiral winding of proposed adoption prepares all-steel meridian line wheel
The method of tire, including prepared offline from extruder and realize steel wire using Wiring apparatus on steel wire cap strip to shaping machine breaker ply drum
Cap strip " S " type spiral winding prepares all-steel radial tyre, and the steel belt of S type spiral winding is inflated swollen through overmolding
After swollen, vulcanization extension process, prefabricated " S " shaped steel wire cap strip changes with design parameter, realizes that steel wire cap strip is stretched completely
Straight or slight bending.
In preceding method, steel wire band all-steel cord after stretching and carcass ply all-steel cord circumferential direction angle≤
1.5°；Basic procedure: steel wire cap strip preparation → steel wire string of a hat crimped → steel wire cap strip S type spiral winding → molding fetus
→ fetus vulcanization → finished tire.
In preceding method, the special tooling of brand-new design and the shape of the mouth as one speaks, preparing width is 6-30mm steel wire cap strip, the steel wire string of a hat
Steel wire density: 3-12 steel wire.
In preceding method, along tire circumferential direction, steel wire cap strip is prefabricated into " S " type using Wiring apparatus in banding interlayer,
Continuous helical winds to obtain " S " shaped steel wire band.
In preceding method, angle corresponding to the pitch of prefabricated " S " shaped steel wire cap strip unit be 10 ° -30 °, one
12-36 " S " shaped steel wire cap strip units are corresponded in a circumference.
In preceding method, " S " shaped steel wire band of spiral winding, adjacent string of a hat stripe pitch 1-10mm, the steel wire of winding
Band is seamless, winds complete layer from starting to terminating using a steel wire string of a hat.
The single steel wire of the steel wire string of a hat stretched in preceding method and carcass ply cord circumferential direction angle≤1.5 °.
Compared with prior art, there are three the advantages of aspect for present invention tool: the first, crown position integral strength is increased,
The wheel anti-puncture ability of crown part is improved, has cushion performance when during tire running by foreign object puncture；The second, the steel wire string of a hat
Layer forms hoop effect to belt and carcass, effectively tire is inhibited to be radially expanded；Banding inter-laminar stress can be reduced, banding is improved
Layer service life and Life of Tyre；Steel wire band after third, winding is distributed average earth pressure after tyre inflating more
Uniformly, the risk failure mode occurrence probability such as wheel crown is quick-fried, top is quick-fried can be reduced.The tire of the invention patent preparation greatly improves
The security performance and service life of tire.
Detailed description of the invention
Fig. 1 is that steel wire cap strip " S " type of the present invention winds schematic diagram；
Fig. 2 is that steel wire cap strip " S " type of the present invention winds partial enlarged view.
Specific embodiment
To make the object, technical solutions and advantages of the present invention clearer, below in conjunction with embodiment to skill of the invention
Art scheme is clearly and completely described, it is clear that the described embodiment is only a part of the embodiment of the present invention, rather than complete
The embodiment in portion, based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, shall fall within the protection scope of the present invention.
Embodiment:
Referring to Figures 1 and 2, the present embodiment provides a kind of steel wire cap strip " S " type spiral windings to prepare all-steel meridian line wheel
The method of tire:
Prepare zero degree steel wire cap strip: design extruder die and tooling realize nullity belt and zero degree steel wire cap strip simultaneously
Production squeezes out the low zero degree steel wire cap strip of the more conventional nullity belt of density, and steel wire cap strip, which has, covers glue protection.
Zero degree steel wire cap strip batches: using taking-up equipment, realizes that the tiling of steel wire cap strip spiral is batched, Screw winding steel
It is isolated when silk cap strip using plastics shield of good preservation effect, realizes that isolation shield and steel wire cap strip synchronous screw batch.
Zero degree steel wire cap strip S type winding: according to different designs parameter, using wrapping machine by steel wire cap strip on banding drum
It is prefabricated into " S " shaped steel wire string of a hat unit, " S " the shaped steel wire string of a hat unit being prefabricated into is continuous, spiral winding obtains respective width
" S " shaped steel wire band, the single steel of steel wire cap strip of " S " shaped steel wire band after molding expansion, vulcanization are upheld, after stretching
Silk and carcass ply cord circumferential direction angle≤1.5 °.Wind angle corresponding to the pitch of prefabricated single " S " shaped steel wire string of a hat unit
It is 10-30 °, 12-36 " S " shaped steel wire string of a hat units is corresponded in a circumference.
The steel wire band that this method is wound forms hoop effect to belt and carcass, effectively inhibits tire radially swollen
It is swollen；Banding inter-laminar stress can be reduced, belt service life and Life of Tyre are improved；Steel wire band after winding fills tire
