Description
Technical field
The invention belongs to tire production technical field, more specifically, more particularly to a kind of production of automobile rubber tire
Technique.
Background technology
Tyre industry belongs to traditional technology-intensive, intensive capital business, and its complex manufacturing, logistics are handed in length and breadth
Wrong, production equipment is more, not only to consider to improve logistics rhythm, reduces the disconnection rate between operation, increases production capacity and obtains bigger
Profit, but also need to consider to reduce non-cutting time, improves the overall coordination of operation.According to the tight of tire production each inter process
Close linking degree, tire production can substantially be divided into several master operations:Mixing process, semi-products operation, severing operation, shaping
Operation, vulcanization process and repair inspection operation.Rise steadily with raw material, cost of labor, equipment cost, energy cost are constantly carried
Height, depends simple expanding production alone and is difficult to obtain bigger profit.Technological innovation and informatization are only constantly carried out, rationally
Using fund, quality from product, make an effort on the rhythm of production logistics, bigger profit can be obtained.
In the past, for the vulcanization process of tire, expand the capsule of balloon-like, from the inside of the unvulcanized tire of shaping by it
Heated sulfurizing mould is pressed to, thus the vulcanization process of tire is carried out.The expansion of capsule is by internally enclosing high temperature
And the steam of high pressure, come what is carried out, between sulfurizing mould and surface of tyre during residual air, surface of tyre depression, produces institute sometimes
A problem that " starved " of meaning.
Additionally, for the vulcanization process of tire, it is proposed that be largely related to release property between unvulcanized tire and capsule
Report, but help to make unvulcanized tire closely along the report of the technology of sulfurizing mould without proposition.
The content of the invention
The invention aims to solve shortcoming present in prior art, and a kind of automobile rubber tire for proposing
Production technology.
To achieve the above object, the present invention provides following technical scheme：
A kind of production technology of automobile rubber tire, including the extrusion of refining glue, tyre surface, curtain and canvas calendering, tyre building, cover tire
Vulcanize and inner tube of a tyre manufacturing process, the tyre building technique is：Bandage is made in carcass drum first, then on beam layer drum
Belt body is made, the laminating of belt and tyre surface is completed with patch method, the carcass that will finally make is unloaded from carcass drum, is covered
Certain size is expanded on to assembly drum, then belt body is set on the assembly drum after expansion, tire is made after rolling
Embryo.
Preferably, it is that the good sizing material of heat refining is machined by extruding that the tyre surface is extruded, and sizing material passes through extruder head
The template in exit, is made the adhesive tape with tyre surface section, shape, heat refining is specifically included successively, for glue, extrusion, marking, cold
But, fixed length cutting, weighing is checked and deposited.
Preferably, the tyre sulfuration method is as follows：
S1, to 0.65-0.7Mpa steam is passed through in curing bag, process time is 3-5min；
S2, discharge internal pressure steam, are passed through 150-160 DEG C of high pressure superheater water, and process time is 0.2-0.5min；
S3, continue to be circulated to being passed through high pressure superheater water in curing bag, the time is 0.25-0.5min；
After S4, the external pressure steam according to needed for existing process is passed through are vulcanized, external pressure steam is drained；
S5, discharge hot water 1.5-2min, make curing bag internal pressure be down to below 0.5MPa；
Hot water in S6, further discharge curing bag, makes curing bag internal pressure be down to below 0.1MPa；
S7, curing bag is vacuumized, make vulcanizate intraluminal pressure be zero, vulcanization terminates.
Technique effect of the invention and advantage：The production technology of a kind of automobile rubber tire that the present invention is provided, with tradition
Technology is compared, and tire curing method of the invention and includes the tire manufacturing method of the vulcanization process, during tyre vulcanization
The not residual air between sulfurizing mould and unvulcanized tire, contributes to unvulcanized tire closely along sulfurizing mould, therefore, it is possible to
Suppress the generation of " starved "；The present invention increases draining action, condensed water is excluded in time, it is ensured that temperature is constant；Can also subtract simultaneously
Few steam loss, reduces production cost.
