Abstract
The invention relates to a compression roller of a tyre forming machine for sticking a tyre layer to a cylindrical drum wheel. The compression roller consists of a shaft core and a roller body arranged on the circumferential surface of the shaft core. The compression roller is characterized in that: the roller body is a silica gel roller body, and the roller body is provided with a plurality of axial through holes; the surface hardness of the silica gel roller body is 25 to 30 Shores A; and the surface hardness range value of the roller body is controlled within 5 Shores A. The roller body has good compressive elastic deformation, the joint quality of a pre-compounded piece and a tire cord is high when the tyre is formed, and the bubble generating probability of the finished tyre is low; and the compression roller has the advantages of simple structure, reasonable design and long service life.
Description
Technical field
The present invention relates to a kind of equipment component of making tire, especially a kind of on cylindrical drum the used tyre building machine pressure roller of applying plies.
Background technology
We know that tire building is a most important link in the tire production.In this link mainly is various parts such as pre-composite members (comprising inner face glue, sidewall), carcass cord, wire loop, tyre surface, belt to be fitted be processed into the tire base.The applying of various mentioned components is to carry out on the assembly drum of tyre building machine, install in the place ahead of pre-composite members of make-up machine and carcass cord feed frame have certain degree of hardness, can be with the pressure roller of the passive rotation of assembly drum, this pressure roller cooperates the applying that compresses with various mentioned components with assembly drum.In the process of fitting, because the difference of each parts curve shape on the pre-composite members, cause former diverse location place to have height fall, all emptyings of gas at different drops place when carrying out the applying of carcass cord, retain more gas in the tire base, gas is concentrated to the tire shoulder and is changed to the tire bubble under the effect of sulfide stress and temperature.The tire bubble not only directly influences the presentation quality of tire, and tire safe capability is had very big potential hazard, easily causes wheel tire shoulder sky, delamination, even explosion.
Depositing tolerance when how to reduce forming process, reduce the generation probability of tire bubble, is each stream in tire manufacturing plant man problem of solving of emphasis always.For example, tyre building machine sponge pressure roller by production of sky, jiangsu wuxi city luxuriant rubber roll Co., Ltd and sale, this sponge pressure roller is made up of axle core and the sponge roll body that is arranged on the core circumferential surface, the sponge pressure roller utilizes it to have the high resiliency characteristics, the pressure roller roll body can carry out strain according to the assembly drum curve when guaranteeing the parts applying, thereby the flatness when increasing the applying of pre-composite members and carcass cord, improve compactness between the two, when fitting, glue-line can drive bubble effectively away, reduce the finished tire bubble and produce probability, glue-line is fitted closely, improve the applying quality of parts in the tire building process.But the sponge pressure roller of said structure, its sponge roll body is under the pressurization situation, and its tearing toughness is low, when surpassing access times (about about 10,000 times), sponge roll body surface promptly produces in various degree wearing and tearing, falls piece, therefore, there is low deficiency in service life.
Summary of the invention
For the roll body surface that overcomes sponge pressure roller in the prior art easily produces wearing and tearing, falls piece, the deficiency that service life is low the invention provides a kind of simple in structure, reasonable in design, long service life, tyre element applying quality height, can effectively reduce the tyre building machine pressure roller that the finished tire bubble produces probability.
The technical solution adopted for the present invention to solve the technical problems is: a kind of tyre building machine pressure roller, it is made up of axle core and the roll body that is arranged on the core circumferential surface, it is characterized in that: described roll body is the silica gel roll body, has several axially extending bores on this roll body.
The case hardness of described silica gel roll body is 25～30 Shao Shi A.
The case hardness extreme difference value of described silica gel roll body is controlled in the 5 Shao Shi A.
The present invention is the silica gel roll body owing to what adopt, and has several axially extending bores on roll body.The deformation behavior of silica gel roll body own is fabulous, and after having several axially extending bores on the roll body, its elasticity of compression distortion then can reach splendid effect.The applying quality of pre-composite members and carcass cord when compared with prior art, the silica gel roll body that has an axially extending bore has greatly improved tire building.Prove that through service test its finished tire bubble generation probability can be controlled at below 0.47%, and relatively stable.It is low that the present invention is simple in structure, reasonable in design, long service life, tyre element applying quality height, finished tire bubble produce probability.
Description of drawings
The present invention will be further described below in conjunction with drawings and Examples.
Fig. 1 is a kind of use installation diagram of the present invention.
Fig. 2 is the cutaway view Amplified image along A-A line among Fig. 1.
Among the figure: 1. a core, 2. roll body, 3. through hole, 4. make-up machine feed frame, 5. forming machine main spindle 6. assembly drums.
The specific embodiment
In Fig. 1, a kind of tyre building machine pressure roller, it is made up of axle core 1 and the roll body 2 that is arranged on a core 1 circumferential surface.
Pressure roller is the place ahead that is installed in make-up machine feed frame 4 through axle core 1.It below this pressure roller the assembly drum 6 that supports by forming machine main spindle 5.Pressure roller cooperates with assembly drum 6 various parts such as pre-composite members (comprising inner face glue, sidewall), carcass cord, wire loop, tyre surface, belt is compressed applying.
The distortion of the compression bullet of the applying quality of pre-composite members and carcass cord and roll body 2 is allo during tire building, and therefore, what its roll body 2 adopted is the silica gel roll body.
In Fig. 2, can reach reasonable compression in order to make roll body 2, silica gel roller wants entire body to carry out the hollow out processing when processing and fabricating, promptly has some axially extending bores 3 on roll body 2.Axially extending bore 3 is offered with different radii rule on roll body 2.As shown in Figure 2, present embodiment is to offer 60 axially extending bores 3 with three different radius rules on roll body 2.
In addition, contrast is the deformation effect of silica gel under different hardness under normal laminate pressure, determines that finally case hardness deformation effect when 25～30 Shao Shi A of roll body 2 is comparatively desirable.
Pressure roller is before installation, at first measure the hardness at each position of silica gel roller roll body with Shore durometer, concrete grammar is along the horizontal direction of roll body 2, every interval 50mm measures once, divide then to revolve for three times and turn 90 degrees each measurement once, guarantee that hardness extreme difference value is controlled in the 5 Shao Shi A scopes, just can guarantee when pre-composite members is fitted with the carcass cord consistently, phenomenon can not occur to a lateral deviation along the stretch ratio at each position of heading.
It is low that the present invention is simple in structure, reasonable in design, long service life, tyre element applying quality height, finished tire bubble produce probability.
