Description

Technical Field

[0002] 17.5 inches is usually the specification of all-steel tires. With the increasing requirements for tire comfort and the development of some high-strength materials, the use of semi-steel radial tire technology can meet the technical requirements of all-steel tires and satisfy people's requirements for comfort. Since the 17.5-inch tire needs to match a rim with a 15-degree inclination angle, which is different from the 5-degree inclination angle rim for ordinary semi-steel tires. Therefore, in order to ensure the matching of the tire and the rim, it is necessary to design the structure of the mold steel ring according to the 15-degree inclination angle rim, and the stress at the bead part of the tire is too concentrated, which easily causes the bead position of the tire to be disengaged from the rim.

For those of ordinary skill in the art, without creative efforts, other drawings can also be obtained based on these drawings.

[0020] In order to make the technical problems, technical solutions and beneficial effects solved by the present application more clearly understood, the following will further describe the present application in detail with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0021] Please refer to Figures 1 to 3 , a mold steel ring for producing 17.5-inch tires, including a steel ring body 1. The inner groove wall 11 of the steel ring body 1 is adapted to a 15-inch tire. The inner groove wall 11 includes an inclined section 111 and a side wall section 112, and an arc 1121 is provided on the side wall section 112.

[0022] A mold steel ring for producing 17.5-inch tires in the present application can effectively disperse stress by setting an inclined section and a side wall section on the inner groove wall of the steel ring body and adding an arc design to the side wall section, avoiding the separation between the bead position and the rim, improving the matching and stability between the tire and the rim, enhancing the durability of the tire, reducing the risk of damage caused by stress concentration, and thus improving the overall performance and service life of the tire.

[0023] Further, as a preferred implementation manner of this solution rather than a limitation, the included angle between the inclined section 111 and the horizontal direction is α, where α = 15°.

[0024] In this embodiment, the perfect matching between the mold steel ring and the 17.5-inch tire is ensured. The setting of this specific angle is beneficial to improving the positioning accuracy and stability during the installation of the tire. Since the inclination matching between the tire and the rim directly affects the balance of the tire and the handling performance of the vehicle, the 15° included angle design greatly reduces the engagement pressure during installation, reduces the installation difficulty, improves the production efficiency, and reduces the manufacturing cost.

[0025] Further, as a preferred implementation manner of this solution rather than a limitation, the radius of the arc 1121 is R, where 12 mm ≤ R ≤ 13 mm.

[0026] In this embodiment, the smooth transition design can better adapt to the elastic deformation of the tire, reduce the separation phenomenon caused by the mismatch between the tire and the steel ring, ensure the tight fit between the tire and the rim, and improve the overall performance of the tire. The arc design within this dimension range also has the advantages of low manufacturing cost and simple process, which is beneficial to reducing the production cost and improving the production efficiency.

[0027] Further, as a preferred implementation manner of this solution rather than a limitation, a plurality of exhaust lines 1111 are provided on the inclined section 111.

[0028] In this embodiment, by increasing the number of exhaust lines, more exhaust channels are provided, which helps to more effectively exhaust the air and volatile substances inside the tire during the vulcanization process, reduce the concentrated accumulation of the rubber compound at the bead position, and thus reduce the formation of bubbles. This not only improves the vulcanization quality of the tire, ensures the uniformity and density of the internal structure of the tire, but also helps to avoid the degradation of tire performance or early damage caused by bubbles. In addition, the uniformly distributed exhaust lines also help to improve the vulcanization efficiency, shorten the production cycle, reduce energy consumption, and at the same time improve the yield and production efficiency of the tire. This design comprehensively considers the production efficiency and product quality, providing a cost-effective and efficient production solution for tire manufacturers.

[0029] Further, as a preferred implementation manner rather than a limitation of this solution, a plurality of the exhaust lines 1111 are evenly distributed along the circumferential direction of the steel ring.

[0030] In this embodiment, it helps to achieve a more balanced exhaust effect during the vulcanization process. Since the exhaust lines are evenly arranged along the circumference, it can ensure that when the tire is vulcanized, the air and volatile substances in each part can be effectively discharged, avoiding bubbles and internal defects caused by poor local exhaust. This layout of evenly distributed exhaust lines helps to improve the overall vulcanization quality of the tire, ensure that the internal structure of the tire is uniformly dense, and enhance the durability and reliability of the tire. At the same time, the evenly distributed exhaust lines can also reduce the uneven pressure during the vulcanization process, help the tire maintain a consistent size and shape, improve the consistency and balance of the tire, which is crucial for improving the handling performance and riding comfort of the vehicle.

[0031] Further, as a preferred implementation manner rather than a limitation of this solution, the radius of the exhaust line 1111 is r, where 0.2 mm ≤ r ≤ 0.4 mm.

[0032] In this embodiment, when it is specifically 0.3 mm, it can provide sufficient channels to discharge the gas generated during the vulcanization process, while avoiding the decrease in the structural strength of the tire caused by too large exhaust holes. The smaller radius helps to maintain the density of the exhaust lines, so as to achieve more uniform gas discharge without sacrificing the overall strength of the tire.

[0033] Further, as a preferred implementation manner rather than a limitation of this solution, there are 16 of the exhaust lines 1111.

[0034] Further, as a preferred implementation manner rather than a limitation of this solution, the radius R of the arc 1121 is 12.5 mm.

[0035] Further, as a preferred implementation manner rather than a limitation of this solution, the radius r of the exhaust line 1111 is 0.3 mm.

[0036] In this embodiment, the reasonable distribution of the radius of the exhaust line also helps to improve production efficiency, can complete the vulcanization process faster, reduce production time, lower energy consumption, and enhance production economic benefits. The setting of the width of this exhaust line plays an important role in improving product quality and production efficiency, avoiding the decrease in the structural strength of the tire caused by too large exhaust holes. The smaller radius helps to maintain the density of the exhaust lines, so as to achieve more uniform gas discharge without sacrificing the overall strength of the tire.

[0037] The working principle of this embodiment is as follows:

[0038] A mold steel ring for producing 17.5-inch tires in the present application can effectively disperse stress, avoid the separation of the bead position from the rim, improve the matching and stability between the tire and the rim, enhance the durability of the tire, reduce the damage risk caused by stress concentration, and thus improve the overall performance and service life of the tire by setting an inclined section and a side wall section on the inner groove wall of the steel ring body and adding an arc design on the side wall section.

[0039] The above are the implementation manners provided in combination with specific contents, and it is not determined that the specific implementation of the present application is only limited to these descriptions. Any approximate similarity to the method structure of the present application, or any technical deduction or replacement made under the premise of the concept of the present application should be regarded as the protection scope of the present application.
