Abstract
The invention relates to a full-scale preform die of an all-steel radial tyre tread. The preform die has a central symmetry structure and comprises a strake rubber channel at the lower part, and a tread rubber channel at the upper part; the full-scale preform die is characterized in that the strake rubber channel at the lower part penetrates from the left to right, and the height in the middle of the strake rubber channel is less than the heights of the two sides of the strake rubber channel. The height of the middle of the tread rubber channel is 27mm, and the width of the middle of the strake rubber channel is 90mm. A tyre tread obtained by adopting the full-scale preform die is characterized by comprising tread rubber, wherein strake rubber layers are on two sides of one surface in which the tread rubber is connected with a belted layer, and the strake rubber layer on the two sides are connected through a transition strake rubber layer. The transition strake rubber layer is 2mm thick. A thin strake rubber cushioning layer is arranged between the tread rubber and the belted layer, so that the problem that the shoulder separation tread rubber generates excessive heat to cause the separation of the tread rubber and the belted layer can be solved.
Description
Technical field
The complete point pre-die that the present invention relates to a kind of all-steel radial tyre tyre surface, belongs to tire production manufacturing technology field.
Background technology
In prior art, the pre-die of all-steel radial tyre tyre surface production and application is shoulder point pre-die and complete point pre-die.Shoulder point pre-die has the tyre surface of le cas d'un pneumatique de type tube-type design mainly for low speed, mining area short distance; Complete point pre-die is mainly for the tyre surface of high speed, the design of middle-long distance type tubeless tyre.Its tread rubber of shoulder somatotype tyre surface directly contacts with belt compound, in actual use, because tread rubber heat-dissipating is large, easily causes, between tread rubber and belt compound, delamination occurs, and reduces Using Life of Tyre, when serious, cause and blows out, and increases potential safety hazard.And full somatotype tyre surface middle part shoulder wing glue thickness is thicker, cause tread rubber gage relatively thin, anti-wear performance reduces, and useful life longevity reduces.
The at present production of all-steel radial tyre tyre surface generally adopts, and sizing material is carried out after compound extruding through die panel (as shown in Figure 2) in pre-die (as shown in Figure 1), reaches required tire tread form and size (as shown in Figure 3).Existing complete point of pre-die as shown in Figure 1, comprises shoulder wing glue passage 1a and tread rubber passage 2a, at shoulder wing glue passage 1a middle part, triangle diffluence pass 3a is set.Triangle diffluence pass 3a, for the shoulder wing sizing material of shoulder wing glue passage 1a is divided into left and right two parts, takes on wing glue 4a part as shown in Figure 3 to form.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of complete point pre-die of all-steel radial tyre tyre surface is provided, make to have between tread rubber and belt compound the shoulder wing glue cushion of thin layer, solve the shoulder point excessive problem that causes delamination between belt of tread rubber heat-dissipating.
According to technical scheme provided by the invention, the complete point pre-die of described all-steel radial tyre tyre surface, symmetrical structure centered by described pre-die, comprises the shoulder wing glue passage of bottom and the tread rubber passage on top; It is characterized in that: the shoulder wing glue passage of described bottom runs through from left to right, and the height of shoulder wing glue channel middle is little compared with the height of both sides.
The height of described tread rubber channel middle is 27mm, and the width of shoulder wing glue channel middle is 90mm.
The tire tread that described employing divides pre-die to obtain entirely, is characterized in that: comprise tread rubber, tread rubber contacts one side both sides with belt are shoulder wing glue-line, between the shoulder wing glue-line of both sides, are connected by transition shoulder wing glue-line.
The thickness of described transition shoulder wing layer is 2mm.
The present invention compared with prior art advantage is: simple in structure, do not change existing equipment structure, entirely divide the pluses and minuses of dividing pre-die with shoulder by reference to prior art, in conjunction with tire design requirement, on the original basis pre-die is redesigned, solve shoulder point tyre surface heat-dissipating and a belt delamination problems, improved and entirely divided that tubeless tyre surface is wear-resisting, durability.

Detailed description of the invention
Below in conjunction with concrete accompanying drawing, the invention will be further described.
As shown in Figure 4: symmetrical structure centered by the complete point pre-die of described all-steel radial tyre tyre surface, comprises the shoulder wing glue passage 1 of bottom and the tread rubber passage 2 on top; The shoulder wing glue passage 1 of bottom runs through from left to right, and the height at the middle part of shoulder wing glue passage 1 is little compared with the height of both sides, thereby the two side portions of shoulder wing glue passage 1 is used to form the shoulder wing glue-line 3 of tire tread both sides, part in the middle of shoulder wing glue passage 1 is used to form the transition shoulder wing glue-line 4 between both sides shoulder wing glue-line 3, as shown in Figure 5;
As shown in Figure 4, the height at described tread rubber passage 2 middle parts is 27mm, and the medium position width that is used to form the shoulder wing glue passage 1 of transition shoulder wing glue-line 4 is 90mm;
As shown in Figure 5, described tire tread comprises tread rubber 5, and tread rubber 5 contacts one side both sides with belt are shoulder wing glue-line 3, between the shoulder wing glue-line 3 of both sides, are connected by transition shoulder wing glue-line 4; The thickness of described transition shoulder wing layer 4 is 2mm.
The present invention does not change existing equipment structure, entirely divides the pluses and minuses of dividing pre-die with shoulder by reference to prior art, in conjunction with tire design requirement, develops and is applicable to produce point pre-die entirely with the thick ultra-thin transition shoulder wing glue-line 4 of 2mm.Compared with original shoulder somatotype tyre surface (as shown in Figure 3), by the design of the thick transition shoulder of 2mm wing glue-line 4, solve the belt delamination problems that tyre surface heat-dissipating problem causes, strengthen anti-ditch fragility; The ultra-thin transition shoulder wing glue-line 4 that 2mm is thick has increased the relative thickness of the wear-resisting glue of tyre surface, has improved that tubeless tyre surface is wear-resisting, endurance quality.The present invention had both met shoulder somatotype mine the inner tube of a tyre, full somatotype middle-long distance tubeless tread design requirement, can solve again the pre-die of the excessive belt delamination problems causing of tread rubber heat-dissipating, middle-long distance tubeless tyre tread rubber gage is improved relatively, and wearability, resiliency, anti-ditch fragility can strengthen.
