Abstract
The invention discloses an all-steel engineering meridian tire reverse-coating capsule. The capsule is prepared from a COP-08A glue material and a 1400dtex/2V1 single-layer cord fabric material containing 100 steel wires per 10cm and having the breaking strength of 21kg per steel wire; a capsule root framework material is a fracture type steel wire cord fabric framework material. The extension strengths of the glue material and the cord fabric meet construction requirements; the capsule root framework material is the fracture type steel wire cord fabric framework material, so that capsule roots can be effectively prevented from springing out. Isolation is carried out by adopting talcum powder, and de-molding is carried out through an inflation and de-molding device, so that adhesion between two layers can be prevented, and the capsule can be smoothly inflated and de-molded.
Description
Technical field
The invention belongs to automobile tire manufacturing technology field, more particularly to a kind of reverse-wrapped capsule and preparation method thereof.
Background technology
Since the debugging of all-steel engineering radial tire building machine, trial-production, the reverse-wrapped capsule used by forming machine is all by Shanghai tire
Rubber group buys, and the capsule service life is 100 times, and every forming machine is averagely produced daily and calculated by 30, and every capsule is average
Using 15 times/day, therefore every capsule average life is 100/15=6.7 days, 10 sets of capsules of company's once outsourcing, and expense is
230000 yuan.If introducing the technology in Shanghai, technology transfer expense is 100,000 yuan, and engineering radial tire yield is 5000 per year, is needed
50 sets of outsourcing capsule is wanted, expense is expected ten thousand yuan of 23*5=115, if our production capacity is expanding 10000 to, then expense is
2300000 yuan, cost is high.And Shanghai capsule we have in use two it is defective in quality, one is gas leakage.Another
That capsule root has breach, we and purchasing department contact seagoing vessel tire group upwards and pursue a claim, ignored in terms of Shanghai at all in order to
Producing cost is reduced, company determines independent research design all-steel engineering radial-ply tyre reverse-wrapped capsule.
Absorb, digest by the capsule produced to Shanghai rubber for tire group, independently carry out detail design, just start trial-production
When using several times with regard to explosion, most uses are 50 times, find that the capsule develops difficulty big, need to solve four in trial-manufacturing process
Key technology difficulty：Capsule upholds big, and, up to more than 250%, the blowing pressure is high for extension rate, and pressure reaches more than 7bar, and this requires capsule
It is not only elastic good, will also strength height.The capsule capsule root framework material should have extensibility, have rigidity again, with prevent capsule root from
Deviate from assembly drum.Processing technology is difficult, and the capsule belongs to thin article, only one layer framework material, and operates by hand completely, appoints
What bubble, joint defect, can all cause the capsule to be scrapped.The capsule length of run up to more than 2 meters, and be eclipsed form, sulfur
After change terminates, it is impossible to the demoulding.In order to detect the service life of capsule, we and equipment are combined and have made ground capsule aerating device,
Inflated using the pressure of 7bar repeatedly, burst until capsule come the service life for determining capsule, in order to avoid testing on forming machine, made
Into the waste of human and material resources, while affecting the carrying out of production.
The content of the invention
To be solved by this invention is that outsourcing capsule has " gas leakage ", the technical problem of " capsule root has breach ", so as to carry
For a kind of all-steel engineering radial-ply tyre reverse-wrapped capsule of low production cost.
Employ the following technical solutions to solve the above problems：A kind of all-steel engineering radial-ply tyre reverse-wrapped capsule, employs
The 1400dtex/2V that COP-08A sizing materials and density are 100/10cm, fracture strength is 21kg/ roots1The material of monolayer cord；
Capsule capsule root framework material takes the wirecord fabric framework material of " breaking type "；Described COP-08A sizing materials are by following weight
The raw material of part is made：65 parts of natural gum, 25 parts of white carbon black, 5 parts of activator, 1 part of age resistor, 3 parts of softening agent, 1 part of vulcanizing agent；It is described
" breaking type " wirecord fabric framework material adopt C60-175W wirecord fabrics, cutting surface width 12cm, density 60/
10cm, steel wire arranging are lateral arrangement；
Its manufacture method is as follows：Capsule shaping drum is attached on forming machine, drum surface is wiped clearly with gasoline, according to sequence of construction number
Upper COP-08A sizing materials, 1400dtex/2V1Monolayer cord, C60-175W wirecord fabrics, filler adhesive tape；After having gone up, external screen is loaded onto
Lid is bolted on, and unloads from forming machine, is attached on bladder curing dolly；After sulfuration kettle cure, then cooling refills
On forming machine, capsule is unloaded, prune unnecessary glue side, to be checked and have bubble-free, starved on capsule capsule root size, capsule；Sulfuration knot
Shu Hou, carries out the demoulding by inflating stripper apparatus, and described inflation stripper apparatus is the extrusion die banjo clip in moulding capsules
Increase a gas tube on tool, inflate between capsule and core before the capsule demoulding, taken off after making capsule and core inflation completely
From the resistance during reduction demoulding ensure that capsule is smoothly disengaged with core, it is to avoid capsule capsule root ruptures.
Sizing material of the present invention and cord tensile strength meet construction requirement, and the capsule capsule root framework material takes " breaking type "
Wirecord fabric framework material, can effectively prevent capsule capsule root from collapsing.
Using Pulvis Talci isolation, and using inflation the stripper apparatus demoulding, can prevent between two-layer bond, can guarantee that glue again
Capsule smoothly inflates the demoulding.
Jing finance measuring and calculating, the capsule that we produce often cover 2200 yuan, according to year engineering radial tire 5000, at least need
50 sets of capsules of purchase, buying expenses is 1,150,000 yuan, deducts 110,000 yuan of our capsule cost, saves 1,040,000 yuan of expense, if work
Journey radial-ply tyre full production, saves expense more significantly.
Specific embodiment
A kind of all-steel engineering radial-ply tyre reverse-wrapped capsule, employs COP-08A sizing materials and density is 100/10cm, ruptures by force
