Abstract
The invention relates to a curvilinear tread combined prefabricated opening model which comprises a prefabricated opening model body. The prefabricated opening model body comprises a left section, a middle section and a right section. The left section and the right section are symmetric about the center line of the middle section, and the left section and the right section are thicker than the middle section. The curvilinear tread combined prefabricated opening model is characterized in that the middle section of the side, combined with tread rubber, of the prefabricated opening model body is linear, the left section and the right section of the side, combined with the tread rubber, of the prefabricated opening model body each comprise a first section and a second section, and the second sections are curvilinear and connected with the first sections and the middle section. The side, combined with base rubber, of the prefabricated opening model body is linear. An inclined face is formed by the top points, connected with the second sections, of the first sections and the side edge of the prefabricated opening model body, and serves as the side face of a tread shoulder in a tire. Size distribution of the base rubber on an original tread shoulder is changed into curvilinear distribution from original traditional parallel distribution in the manner of the curvilinear tread combined prefabricated opening model, and therefore the tire shoulder heat dissipating of the tire is obviously improved, and the quality of a product is improved.
Description
Technical field
The present invention relates to a kind of tire tread composite reserved-port, especially a kind of curvilinear style tyre surface composite reserved-port, belong to tyre technology.
Background technology
Existing wheeled vehicle, particularly Large freight load-carrying vehicle, they run quickly on highway, should the most again safety but also energy-conservation, the tire of load-carrying vehicle is had higher requirement by these targets.And tire is substantially and is made up of nine big base components such as crown, sidewall, triangle, pad glue, inner liner, belt, carcass, chafer, wire loops, key point therein mainly has two large divisions: be first the crown of tire, next to that the skeleton construction of tire (such as belt, carcass, chafer, wire loop).The most particularly crown of tire is particularly important, because the crown of tire is the bridge connecting ground with tyre framework material, crown reasonable in design makes tyre surface during tire used can be evenly transferred on tire belt and carcass by the active force on ground, make tire uniform stressed, just make tire tread embody the adhesion property of excellence in actual use, play the high efficiency hauling operation that Duola hurries up.
High-performance tire tyre surface is typically made up of the tread rubber of high-wear resistance and the base rubber of low-heat-generation.After in actual production process, two kinds of sizing materials are by different extrusion screw rod extrusions, it is combined with each other by pre-die.Pre-die plays the pivotal role that two kinds of sizing materials are combined and control parts compound shape.In current each tire enterprise, the composite surface of pre-die typically uses traditional straight line complex form, is illustrated in figure 1 prior art cathetus type pre-die.There is following defect in above form in actual production process: although a pre-die composite surface is straight line, but owing to rubber belongs to viscoelastic body, in actual Screw Extrusion, the diversity of left, center, right glue supply causes actual rubber combined face to be in the situation that intermediate thin both sides are thick, the reaching of non-entirely accurate designs requirement, and then have impact on tire product quality；Two, the tyre surface (as shown in Figure 2) after being combined by this pre-die, distribution at final tire section shoulder sizing material presents curve, both sides sizing material is thicker, it is difficult to distributing of tire heat, the gathering of high temperature makes tire occur herein takeing on the problems such as empty, U-shaped explosion, directly affects the service life of tire.It is concrete as it is shown on figure 3, the thickness of shoulder B is substantially thicker than the thickness of the average A of tyre surface.
Summary of the invention
It is an object of the invention to overcome the deficiencies in the prior art, a kind of curvilinear style tyre surface composite reserved-port is provided, regulation not only by curved surface makes the composite surface of tyre surface keep linear structure, and optimizes the material distribution of tread shoulder tread rubber, base rubber, improves Life of Tyre.
The technical scheme provided according to the present invention, described curvilinear style tyre surface composite reserved-port, including pre-die body, pre-die body includes left section, stage casing and right section, and left section and right section symmetrical with the centrage in stage casing, left section and right section of the most relatively stage casing thickness；It is characterized in that: described pre-die body and tread rubber are combined the stage casing linearly type of side, pre-die body and tread rubber be combined side left section and right section includes first paragraph and second segment respectively, second segment curved type connection first paragraph and stage casing.
Further, the side linearly type that described pre-die body is compound with base rubber.
Further, the side on summit and pre-die body that described first paragraph connects second segment forms inclined-plane, and this inclined-plane is the side of tread shoulder in tire.
Further, described pre-die is combined in the tire of tyre surface, and the second segment of left section and right section is connected shape linear type with stage casing.
Curvilinear style tyre surface composite reserved-port of the present invention by original tread shoulder base rubber distribution of sizes by the most traditional parallel distribution, tread slab base is made to change curve distribution in the distribution of tire shoulder by the way of using shaped form composite reserved-port, thus significantly improve the tire shoulder heat of tire, improve the quality of product.

Detailed description of the invention
Below in conjunction with concrete accompanying drawing, the invention will be further described.
Shown in Fig. 4～Fig. 6: as described in curvilinear style tyre surface composite reserved-port include pre-die body 1, left section 11, stage casing 12, right section 13, first paragraph 21, second segment 22 etc..
As shown in Figure 4, Figure 5, curvilinear style tyre surface composite reserved-port of the present invention, including pre-die body 1, pre-die body 1 includes left section 11, stage casing 12 and right section 13, left section 11 and right section 13 symmetrical with the centrage in stage casing 12, and left section 11 and right section 13 the most relatively stage casing 12 is thick；The side linearly type that described pre-die body 1 is compound with base rubber, pre-die body 1 and tread rubber are combined the stage casing 12 linearly type of side, pre-die body 1 and tread rubber be combined side left section 11 and right section 13 includes first paragraph 21 and second segment 22 respectively, and the curved type of second segment 22 connects first paragraph 21 and stage casing 12.The side on summit and pre-die body 1 that described first paragraph 21 connects second segment 22 forms inclined-plane, and this inclined-plane is the side of tread shoulder in tire.
Pre-die and tyre surface are combined one side and use curve form by the present invention, are made the composite surface of tyre surface keep linear structure by the regulation of curved surface.The present invention changes the parallel distribution that tread shoulder base rubber in prior art is traditional, as shown in I in Fig. 3.As shown in Figure 6, shaped form pre-die of the present invention is combined tread slab base and is distributed as curve distribution, as shown in J in Fig. 6 at tire shoulder；In tire, the thickness of the shoulder B thickness equal to the average A of tyre surface.
Described curvilinear style tyre surface composite reserved-port uses protruding reverse radian in both sides so that shoulder region base rubber distribution of sizes is more reasonable.Thus significantly improve the tire shoulder heat of tire, improve the quality of product.The present invention makes the composite surface of tyre surface keep linear structure not only by the regulation of curved surface, and optimizes the material distribution of tread shoulder tread rubber, base rubber, improves Life of Tyre.
