Abstract
The invention discloses a kind of non-inflatable tyre wheel hub integral forming process, comprising the following steps: according to the circumference of tyre surface, the tyre surface raw rubber that extruder is squeezed out is cut, and head and the tail gluing；Injection molding machine is in injection molding inner tube of a tyre material in inner tube mold；Tyre surface raw rubber after gluing is placed in the outer surface of inner tube of a tyre material, it is co-vulcanized, complete vulcanization, the inside inner tube of a tyre crosslinked foaming of exterior tread；Meanwhile one finished product is made after the inner surface injection molding boss material of inner tube of a tyre material, integrated cooling and shaping by hub mold.Compared with prior art, tyre surface, carcass (inner tube of a tyre), wheel hub are integrally formed, vulcanization, foam process, wheel hub are formed while being carried out, carcass, tyre surface and wheel hub closely bond, there is no bead seats to be layered hidden danger, and product quality is more stable, and wear-resisting puncture resistance is more preferably, it is particularly suitable for shared bicycle, there is very strong practicability and wide applicability.
Description
Technical field
The present invention relates to a kind of tyre forming process, and in particular to a kind of non-inflatable tyre wheel hub integral forming process.
Background technique
Traditional tire building is to produce tyre surface by the design requirement of tire, carcass is molded on molding machine, then will
Tyre surface and carcass, which are bonded or are wound on molding machine, to be combined, and an embryo is made, then place it in vulcanizing agent and carry out
Sizing, vulcanization obtain finished product, then fix with independent wheel hub.
Due in conventional molding process tyre surface and carcass be all it is uncured, they carry out shaping sulphur in vulcanizer
When change, tyre surface and carcass can all uphold deformation, and quality is not easily controlled, and there are hidden danger, especially high speed for carcass and tyre surface combination
When driving, and wear-resisting, the puncture resistance of tire be will affect；And after the fixed firmness and long-time use of wheel hub
Situation is loosened, the security performance of vehicle is also influenced.
Summary of the invention
To solve the deficiencies in the prior art, the purpose of the present invention is to provide a kind of carcass, tyre surface and wheel hubs to closely bond,
The more stable non-inflatable tyre wheel hub integral forming process of quality.
In order to achieve the above objectives, the present invention adopts the following technical scheme that:
A kind of non-inflatable tyre wheel hub integral forming process, comprising the following steps:
S1, the circumference according to tyre surface, the tyre surface raw rubber that extruder is squeezed out is cut, and head and the tail gluing；
S2, injection molding machine are in injection molding inner tube of a tyre material in inner tube mold；
S3, the outer surface that the tyre surface raw rubber after gluing is placed in inner tube of a tyre material, it is co-vulcanized, complete exterior tread vulcanization,
Internal inner tube of a tyre crosslinked foaming；
S4, simultaneously passes through hub mold, is molded boss material in the inner surface of inner tube of a tyre material, after integrated cooling and shaping, is made one
Body finished product.
The extrusion temperature of tyre surface raw rubber is 60-90 DEG C in above-mentioned steps S1.
Curing temperature in above-mentioned steps S3 is 160-200 DEG C, and sulfide stress is consistent with traditional sulfide stress.
Vulcanization in above-mentioned steps S3 is carried out in vulcanizing press or annular vulcanizer, and the pressure of presulfurization is
30-70kg/cm2。
The injection molding of above-mentioned inner tube of a tyre material and boss material, using double-station injection molding machine, drop can be jacked up by being molded wheelboss part
Under.
Above-mentioned boss material includes glass fiber reinforced nylon material.
The invention has the beneficial effects that:
A kind of non-inflatable tyre wheel hub integral forming process of the invention, compared with prior art, tyre surface, carcass (inner tube of a tyre), wheel
Hub is integrally formed, and vulcanization, foam process, wheel hub are formed while being carried out, and carcass, tyre surface and wheel hub closely bond, and tire is not present
Wheel hub is layered hidden danger, and product quality is more stable, and wear-resisting puncture resistance more preferably, is particularly suitable for shared bicycle, has very strong
Practicability and wide applicability.
Specific embodiment
Below in conjunction with detailed description of the invention by specific embodiments.
According to design requirement, tyre surface, the inner tube of a tyre, the material prescription of wheel hub and size are determined.
A kind of non-inflatable tyre wheel hub integral forming process, comprising the following steps:
S1, the circumference according to the tyre surfaces of 24 cun of tires, the tyre surface raw rubber that extruder is squeezed out are cut, and 60-90 DEG C of processing temperature,
And utilize rubber adhesive head and the tail gluing；
S2, using double-station injection molding machine in inner tube mold be molded inner tube of a tyre material；
S3, the outer surface that the tyre surface raw rubber after gluing is placed in inner tube of a tyre material, jointly in 170-180 DEG C of temperature in vulcanizing press
Vulcanized under degree, completes the vulcanization of exterior tread, internal carcass crosslinked foaming；The pressure of presulfurization is 30-70kg/cm2。
S4, vulcanization jack up hub mold simultaneously, by using double-station injection molding machine, are molded wheel in the inner surface of inner tube of a tyre material
After integrated cooling and shaping, one finished product is made in hub material.
Boss material includes glass fiber reinforced nylon material.
Inner tube of a tyre material includes following mass component: rubber-like materials 50-100, resin 10-50, fills oil 10-50, filler
