Description
Technical field
This utility model is related to automobile production manufacturing technology field and in particular to the mould of a kind of inner tube of a tyre and the inner tube of a tyre.
Background technology
Tire is mainly made up of cover tire, the inner tube of a tyre and rim strip, and the inner tube of a tyre is the pith of tire, and the inner tube of a tyre is commonly called as inner tire, refers to
For keeping inner pressure of tire, the annular elastic tube with tyre valve, the inner tube of a tyre is typically fabricated by by elastomeric material, is used for
The elastomeric material manufacturing the inner tube of a tyre has polytype, such as butyl rubber and natural gum etc..Valve cock is in order to inflate and so that air is existed
Certain pressure is kept, the inner tube of a tyre should have good air-tightness, thermostability, elasticity, resistance to ag(e)ing and less permanent change in the inner tube of a tyre
Shape.The inner tube of a tyre carries provides the blowing pressure for tire, so that tire obtains tire elasticity and the important function of bearing capacity, is relation
Vitals to the person and vehicle safety.
Substantially can be divided in the technological process that the inner tube of a tyre produces: the preparation of inner tube rubber, the extrusion of inner tube of a tyre sicula, inner-tube
The joint of pipe and tyre tube vulcanizer.In the production and processing of the inner tube of a tyre, the inner tube of a tyre packing element extruded by extruder is a tubular rubber
Pipe, then installs valve cock on tubular sebific duct, it is made the inner tube of a tyre, also will be docked through splicer, the inner tube of a tyre
Docking makes the inner-tube cylinder of high temperature by tube splicer heat-fastening knife to the cutting at inner tube semi-finished product tire cylinder two ends and docking compression
Two ends engage.Before sulfuration, inner-tube pipe has plasticity, and the sicula through equipment extrusion molding need to after overall dimensions sizing again
Sulfuration forms the inner tube of a tyre meeting dimensional requirement, heating sulfuration sizing generally in tyre tube vulcanizer mould.
In the production technology of the inner tube of a tyre, because the inner tube of a tyre takes joint technology so that inner tube semi-finished product tire cylinder two ends is engaged, this
The intensity that sample easily causes at tube changes, it will produce fatal impact to inner tube of a tyre quality, such as when the inner tube of a tyre enters
Exercise the used time, because the inner tube of a tyre and cover tire need together with tight pressing, the inner tube of a tyre will be squeezed by outside high pressure, side pressure and friction
Pressure etc., and because the intensity at tube position is relatively poor, therefore this position is very easy to squeeze in high pressure, side pressure and friction
Rupture under the modes such as pressure, and then shorten the service life of the inner tube of a tyre.
Utility model content
In order to solve the above problems, this utility model provides a kind of inner tube of a tyre, it is to avoid the intensity at tube becomes
Change and affect the quality of the inner tube of a tyre.
The technical solution of the utility model is: a kind of inner tube of a tyre, including carcass and be arranged at valve cock on carcass, in institute
State and at the joint area of carcass, be provided with the first reinforcement elements, described first reinforcement elements are by multiple along carcass outer peripheral face cincture cloth
The bulge loop muscle composition put.
If the intensity of joint changes, because this utility model is provided with bulge loop muscle knot at carcass joint area
Structure, bulge loop muscle can play the effect as reinforcement, and multiple bulge loop muscle are arranged at carcass joint area and form the first reinforcing list
Unit, the first reinforcement elements can strengthen the intensity of joint, it is to avoid the intensity of joint changes and affects the quality of the inner tube of a tyre.
Although bulge loop muscle is thinner, inner tube of a tyre outer wall and cover tire inwall also it have been effectively isolated so that there is very little between the inner tube of a tyre and cover tire
Gap so that the inner tube of a tyre is not together with tight pressing with cover tire, can effectively protect the connector portions of the inner tube of a tyre carcass during use
Intensity weak position in position is subject to the mode such as high pressure, side pressure, friction and Extrusion to rupture, thus strengthening tube position, improves
The robustness of the inner tube of a tyre.
Preferably, the described bulge loop muscle in the first reinforcement elements is consistent with described carcass material, bulge loop muscle and carcass one
Body is compressing.In this utility model, bulge loop muscle is consistent with carcass material, and is integrally formed, and not only can improve the matter of the inner tube of a tyre
Amount, and make the first reinforcement elements processing more convenient.
Preferably, the second reinforcement elements are provided with the outer peripheral face of described carcass, the second reinforcement elements by multiple along
Carcass outer peripheral face is around the bulge loop muscle composition of arrangement.
Preferably, the described bulge loop muscle in the second reinforcement elements is consistent with described carcass material, bulge loop muscle and carcass one
Body is compressing.
In the manufacturing process of the inner tube of a tyre, when the carcass of semi-finished product is carried out sulfidization molding, need for carcass to be positioned over mould
Sulfidization molding in tool, make while sulfidization molding bulge loop muscle also molding together, therefore operator it needs to be determined that carcass connector portions
After the position at position place, then carcass is positioned in mould, in order to improve work efficiency, is easy to processing, preferably, described the
Two reinforcement elements are symmetrical arranged centered on valve cock with the first reinforcement elements.When carrying out sulfuration processing, valve cock can be made
For the object of reference of joint area, because place symmetrical centered on valve cock is provided with the first reinforcement elements and the second reinforcement elements,
When processing, operator need not take time to confirm the position at joint area, you can guaranteeing can be by bulge loop at joint area
Muscle is machined at joint area.
In this utility model the version of bulge loop muscle can have multiple, preferably, described first reinforcement elements and
Multiple bulge loop muscle in two reinforcement elements are evenly arranged each along the circumference of carcass.
So that the setting of the first reinforcement elements and the second reinforcement elements is played while raising intensity it is impossible to affect tire
The original performance of body, preferably, the distance between adjacent bulge loop muscle is 0.2～0.4cm in described first reinforcement elements；Second
In reinforcement elements, the distance between adjacent bulge loop muscle is 0.2～0.4cm.
