Abstract
The invention discloses a novel nylon rubber ring used for a tyre manufacturing process. The nylon rubber ring is a solid ring which is made of nylon and a high-elasticity rubber material and has a certain section shape, is used in a molding procedure of the tyre manufacturing process, and is a key part used in a process for assembling a semi-finished product tyre into a finished product tyre. According to the rubber ring disclosed by the invention, the service life can be prolonged by additionally sticking the nylon, and the cost is reduced; and the kneading force and the whole strength of a tyre bead part of the tyre are improved; and the endurance performance of a tyre bead of the tyre is greatly improved.
Description
Technical field
The present invention relates to a kind of nylon rubber circle for tire production.
Background technology
Rubber ring is that in tire production, molding procedure uses, and during use, it is arranged on shaping drum for tyre shaping machine.The rubber ring that existing assembly drum uses is pure glue goods, and long-time use deformation is comparatively large, and repeatedly along with the action of assembly drum lock dog, repeatedly props up and fall, and folder edge position stretches comparatively large, and damage is frequent, and service life is low.
Therefore, a kind of new rubber ring is needed to use problem in service life, significantly to reduce molding procedure production cost better to solve it.Can also avoid damaging the gas leakage situation occurred when using simultaneously, ensure tire building quality.
Summary of the invention
In view of this, the invention provides a kind of nylon rubber circle for tire production, better solve the problem in service life of rubber ring.
The present invention solves this technical problem adopted technical scheme:
A kind of nylon rubber circle for tire production, comprise solid rubber ring body and the folder edge of edge, side, folder edge indent forms three-back-shaped semitight groove, three-back-shaped folder edge has internal diameter mouth near rubber ring body on internal diameter, it is characterized in that, the inner face of described semitight groove sticks on nylon, nylon stick on the edge surface that internal diameter mouth is vacated in position.
Nylon rubber circle for tire production according to claim 1, is characterized in that, described nylon ultimate strength >=98N/ root, elongation at break 14.0 ± 1.5%, strength irregularity≤4.0%, uneven rate of elongation≤6.0%.
Elastomeric nylon and rubber ring are the solid rim possessing certain section configuration, be combined as in Finished product processThe by tire use by various semi-finished product.
Rubber ring of the present invention, by sticking on nylon, can increase the service life, reduce costs, and improves kneading power and the bulk strength at tire bead position, has increased substantially the bead durability energy of tire.
Accompanying drawing explanation
Below with reference to accompanying drawings specific embodiment of the invention scheme is described in detail, wherein:
Fig. 1 is nylon rubber coil structures of the present invention,
Fig. 2 is nylon rubber circle section configuration of the present invention.
Reference numeral: 1, rubber ring body, 2, folder edge, 3, nylon, 4, semitight groove, 5, internal diameter mouth.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the invention will be further described:
The present invention as shown in Figure 1,
For the nylon rubber circle of tire production, comprise solid rubber ring body 1 and the folder edge 2 of edge, side, folder edge 2 indent forms three-back-shaped semitight groove 4, three-back-shaped semitight groove has internal diameter mouth 5 near rubber ring body 1 on internal diameter, it is characterized in that, the inner face of described semitight groove 4 sticks on nylon 3, nylon 3 stick on the edge surface that internal diameter mouth 5 is vacated in position.
According to the described nylon rubber circle for tire production, it is characterized in that, described nylon 3 ultimate strengths >=98N/ root, elongation at break 14.0 ± 1.5%, strength irregularity≤4.0%, uneven rate of elongation≤6.0%.
Described non junction rubber ring for by extruding, injection moulding, sulfuration etc. one or more process.
Finished product uses contrast to realize
The tyre model of carrying out contrast experiment is 12.00R20-18PR, and contrast test adopts nylon rubber circle of the present invention and tradition not to paste nylon rubber circle respectively, and other tyre semi-finished products and structure are all identical, and contrast experiment is as follows:
1) bead durability can be tested
Adopt a Tire testing drum, experiment tire is installed on the wheel rim of a standard, fill with the air pressure of 650Kpa (standard inflation pressure is 830 Kpa), and load the load 7500Kg of 200%, rotate with the linear velocity of 30 kilometers/hour under the environment temperature of 35 DEG C; Until damaging appears in this tire, tyre rotation time when record damages.In Table 1, experimental result represented with the time (h), and the time is longer, and tire bead endurance quality is better.
2) contrast in service life
Stereosphere or a steel ring cost index represent, and this index is with existing traditional steel ring for a reference value 100, and this index is higher, and production cost is higher.
