Abstract
The port machine tire producing process features that the tire tread and the tire body are first produced separately and then combined to form the tire. The producing process includes 1.producing tire body through adhering and forming cord fabric and forming the tire ring; 2producing tire tread through extruding tire tread strips and vulcanizing; and 3.assembling and adhering the tire body and the tire tread to form, and low temperature vulcanizing to obtain the tire product. The separately produced tire tread has high density, raised wear resistance and long service life.
Description
Technical field
The present invention relates to a kind of manufacture method of port machine tyre, specifically to the improvement of the manufacture method of existing port machine tyre.
Background technology
At present, the supporting tire that does not does not manufacture and design for port loading and unloading machinery specially generally selects for use engineering tyre to substitute both at home and abroad.Port machine tyre characteristics in use are: (1) under heavy load, tyre crown damages fast, and then discarded, and for example, bridge crane tire service life is 1 to 1 year about half, and front hanging wheel tire service life only be individual month of 3-6.(2) under artesian condition, when carrying out " reversing ", phenomenon such as usually can cause delamination, tear, blow out causes damaged tyres.
Owing to, estimate about 150,000 of the annual demand of a bridge crane tire along with the port machine tyre demand is more and more big; About 450,000 of the annual demand of front hanging wheel tire, owing to demand constantly increases, thereby the user more and more pays close attention to service life and the problem that reduces cost.
But the manufacture method and the process of existing engineering tyre are carcass building moulding → tyre bead moulding → tread rubber (crown, tire shoulder, sidewall) assembly → sulfuration → finished product.Crown be tire ground connection wearing and tearing parts, make with its carcass is whole.
The deficiency of this process is: this traditional manufacturing tire method is to use inner tube of a tyre water-filling press cure in model, and sulfide stress is generally 20kg/cm
2About, sulfide stress is low, thereby the crown density is on the low side, wears no resistance, and intensity is low, and service life is low, can not adapt to the heavy duty of port machine tyre and reverse requirement.
How solving above-mentioned deficiency, then is the design problem that the present invention faced.
Summary of the invention
The invention provides a kind of manufacture method of port machine tyre, problem such as it is low that it can solve the crown density that prior art exists, and wears no resistance, and intensity is low, and service life is low.
In order to reach the purpose that solves the problems of the technologies described above, technical scheme of the present invention is, a kind of manufacture method of port machine tyre is characterized in that crown is separated from carcass, makes respectively, and described method is carried out as follows:
(1) make no crown glue carcass: the carcass building moulding → no crown carcass of tyre bead moulding → manufacturing (crown only applies 5～15mm film, tire shoulder, sidewall) assembly → sulfuration, make the semi-finished product carcass;
(2) crown manufacture method, the crown extrusion molding is also made ribbon, adopts the vulcanizing press sulfuration, faying surface place, two ends adopts presulfurization, and all the other positions are optimum cure, after all the other position optimum cures, when faying surface is replenished the annular sulfuration, make the phase reach optimum cure, standby;
The semi-finished product of the no crown carcass that (3) will make and crown assembling assembly carry out cryogenic vulcanization again to finished product.
In the method for the invention, also has following technical characterictic: before the combination of no crown carcass and crown, to the processing such as polish of no crown carcass and crown.
In the method for the invention, also have following technical characterictic: when will not have the sulfuration of crown carcass and crown combination forming, adopt cryogenic vulcanization, curing temperature is 80～120 ℃.
In the method for the invention, also have following technical characterictic: crown is made strip earlier, model two ends water flowing semi-cure during sulfuration, and all the other position optimum cures, sulfide stress is 80～150kg/cm
2When replenishing the annular sulfuration, only the two ends semi-cure is partly overlapped, make it reach optimum cure through sulfuration again.
In the method for the invention, also have following technical characterictic: when annular faying surface replenishes sulfuration, should carry out grinding process in lap-joint, and the brushing rubber cement, replenish sulfuration after the volatilization.
The present invention compared with prior art has the following advantages and good effect:
Crown is isolated from carcass, made respectively, then synthetic again one.Because crown is made respectively with no crown carcass, carry out assembled formation again, thereby can carry out special processing at crown, as adopting the vulcanizing press sulfuration, compression molding pressure is much higher than classical production process.The raising of sulfide stress improves sulfuration tyre surface compactness, thereby has improved wearability, and prolong service life, our experiments show that about on average doubling service life, to have great technical economic benefit.
Description of drawings
Below in conjunction with drawings and Examples the present invention is described in detail.
Fig. 1 is that the present invention is the schematic diagram of presulfurization strip crown;
Fig. 2 is that the present invention is the schematic diagram of annular sulfuration overlapping part crown.
1. crown; 1-1. faying surface; 1-2. optimum cure face
The specific embodiment
Embodiment, carry out as follows:
(1) the carcass building moulding → no crown tread rubber of tyre bead moulding → manufacturing (promptly only to tire shoulder, sidewall assembly) → sulfuration → standby;
(2) crown manufacture method, the crown extrusion molding is also made strip, the sulfuration of employing vulcanizing press, faying surface place, two ends adopts semi-cure, semivulcanized degree be optimum cure 30%～70% before, all the other positions are optimum cure, after all the other position optimum cures, faying surface is replenished annular sulfuration, make it reach optimum cure → standby;
(3) the no crown tread rubber that will make and crown assembling assembly carry out cryogenic vulcanization again to finished product.
In above-mentioned (2) operation, adopt swan neck press that faying surface is replenished the annular sulfuration, make it reach optimum cure.
In above-mentioned (2) operation, after lap-joint should carry out grinding process, should the brushing rubber cement, replenish sulfuration after the volatilization.
In said method, strip crown sulfide stress is 80-150kg/cm
2
Choosing of the number range in above-mentioned numerical value interval can be chosen according to some factors in the actual process process.
The above only is preferred embodiment of the present invention, is not to be the restriction of the present invention being made other form, and any technical staff who is familiar with this patent may utilize the technology contents of above-mentioned announcement to be changed or be modified as the equivalent embodiment of equivalent variations.But every technical solution of the present invention content that do not break away to any simple modification, equivalent variations and remodeling that above embodiment did, still belongs to the protection domain of technical solution of the present invention according to technical spirit of the present invention.
