Technical Field
The utility model relates to the technical field of tire tread extrusion pre-opening shapes, in particular to a novel all-steel layered tire tread pre-opening shape.
Background
As shown in fig. 4, the main role of the tread rubber in all-steel tires is to resist wear and to provide sufficient friction by means of deformation of the blocks and rubber. At present, the tread rubber of the tire is designed by adopting single tread rubber, but in the actual use process, even if the tire is worn to the safety mark, a large amount of tread rubber still remains, and the part of rubber material does not participate in the abrasion all the time, so that the cost waste is caused.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problem, the utility model provides a novel all-steel layered tread pre-opening type.
In order to solve the technical problems, the utility model adopts the following technical scheme:

a frame;
the tire wing rubber flow channel is arranged on the frame, and the tire wing rubber flow channel is arranged on the frame;
a pre-die detachably disposed in the pre-die mounting opening;
a second tread rubber flow channel and a base rubber flow channel which are arranged on the pre-opening type; and the second tread rubber flow channel and the base rubber flow channel penetrate through the pre-opening.
Further, the second tread rubber flow channel and the base rubber flow channel are both semi-closed flow channels; when the pre-die is installed in the pre-die installation opening, the second tread rubber flow channel and the base rubber flow channel form a closed flow channel together with the side wall of the pre-die installation opening.
Further, on the frame, the heights of the wing rubber flow channel, the first tread rubber flow channel, the second tread rubber flow channel and the base rubber flow channel are sequentially reduced; along the flowing direction of the rubber material, the wing rubber flow channel and the first tread rubber flow channel are inclined from top to bottom, and the base rubber flow channel is inclined from bottom to top.
Compared with the prior art, the utility model has the beneficial technical effects that:
aiming at the problem that part of tread rubber does not participate in abrasion, the tread structure is redesigned, the tread pre-opening shape is changed, a second tread rubber flow channel is added below the first tread rubber flow channel, and rubber materials with low abrasion and low heat generation formula enter the second tread rubber flow channel, so that the cost is reduced, and the performance is improved; in addition, part of the general rubber material flow channels are integrated on the frame, the second tread rubber flow channel and the base rubber flow channel are left on the pre-opening type, the production of single treads and double treads can be switched by replacing the pre-opening type on the frame, the production of treads with different widths can also be switched, the reuse capacity and the size expansion capacity of the frame are improved, and the overall weight of the pre-opening type is reduced.

Detailed Description
A preferred embodiment of the present invention will be described in detail below with reference to the accompanying drawings.
As shown in FIG. 3, for the problem that part of the tread rubber does not participate in abrasion, a second tread rubber needs to be added under the first tread rubber and the groove, and the second tread rubber adopts a formula with low abrasion and low heat generation, so that the cost is reduced and the performance is improved.
The new tread design of the structure for adding the second tread rubber is complex, and the composite surface structure has a large amount of indirect structures and cannot be realized by adjusting the pressure among the rubbers.
After a plurality of tests, a scheme of determining the shape of a roughly composite surface by forced distribution (namely the shape of the pre-opening die 5) and then finely adjusting the rotation speed and the pressure of the screw is selected.
Specifically, the layered tread pre-lip comprises: the tire tread rubber flow channel comprises a frame 1, a pre-opening type 5, a first tread rubber flow channel 3, a wing rubber flow channel 2, a pre-opening type mounting opening 4, a second tread rubber flow channel 6 and a base rubber flow channel 7.
Fig. 1a and 1b are a front view and a cross-sectional view of a first tread rubber flow channel, a wing rubber flow channel and a pre-opening type mounting opening respectively.
Fig. 2a and 2b are a front view and a cross-sectional view of a pre-lip, a secondary tread rubber flow channel and a base rubber flow channel, respectively.
The pre-mouth 5 is detachably arranged in the pre-mouth mounting opening 4; the first tread rubber 10 passes through the first tread rubber flow channel 3, the wing rubber 30 passes through the wing rubber flow channel 2, the second tread rubber 20 passes through the second tread rubber flow channel 6, and the base rubber 40 passes through the base rubber flow channel 7 to pass through the layered tread pre-opening. The heights of the tire wing rubber flow passage 2, the first tread rubber flow passage 3, the second tread rubber flow passage 6 and the base rubber flow passage 7 are sequentially reduced; along the flowing direction of the rubber material, the wing rubber flow passage 2 and the first tread rubber flow passage 3 are inclined from top to bottom, and the base rubber flow passage 7 is inclined from bottom to top.
In the prior art, all the flow channels are arranged on the pre-opening type 5, so the pre-opening type 5 has larger volume and weight and high operation strength; in the utility model, a universal first tread rubber flow channel 3 and a universal wing rubber flow channel 2 are integrated into a frame 1, only a second tread rubber flow channel 6 and a base rubber flow channel 7 are reserved on a pre-opening type 5, and the second tread rubber flow channel 6 and the base rubber flow channel 7 are semi-closed flow channels, so that when the pre-opening type 5 is arranged in a pre-opening type mounting opening 4, the second tread rubber flow channel 6 and the base rubber flow channel 7 and the side wall of the pre-opening type mounting opening 4 form a closed flow channel. The size and the weight of the pre-opening type 5 are reduced by the scheme, and the operation strength can be reduced; meanwhile, the repeated processing capacity and the size expansion capacity in the later period are improved, namely, the size of the tread rubber or the design of the tread can be changed by replacing different pre-opening types 5.
After the sizing material passes through the layered tread pre-opening type, the sizing material also needs to pass through the opening type to finally generate a tread finished product, and because the tread finished product has a complex structure and the second tread rubber is required to be lower than a pattern groove, the design has higher requirement on the stability of the product, and the stability among batches of the product size can be improved by the modes of canceling the opening type back groove, increasing the thickness of the opening type, increasing the sizing material shaping length and the shaping time, reducing the width coefficient of the opening type and increasing the extrusion pressure; the die design is not described in detail since it is not within the scope of the present invention.
The utility model realizes the production of the tread with a new structure comprising the second tread structure and ensures the production stability.
It will be evident to those skilled in the art that the utility model is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the utility model being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein, and any reference signs in the claims are not intended to be construed as limiting the claim concerned.
