Description

Technical Field

[0001] This utility model belongs to the field of tire tread pressing technology, specifically relating to a new type of steel sheet for tire tread pressing. Background Technology

[0002] Currently, tires can become difficult to brake and control in adverse weather conditions such as rain or snow, reducing safety and increasing the risk of traffic accidents. To ensure braking performance, additional steel grooves are often added to the tire tread.

[0003] Currently, the tire tread pattern produced by pressing steel sheets has poor tear resistance. At the same time, it is difficult for the rubber material to separate from the steel sheet during demolding, which often causes tread damage and affects the appearance and quality of the tire. Utility Model Content

[0004] The purpose of this invention is to provide a novel steel sheet for tire tread pressing that offers rapid separation and stable tread structure in order to solve the aforementioned problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A novel steel sheet for tire tread pressing includes a steel sheet body and a mounting plate disposed on the steel sheet body, wherein the steel sheet body has a wavy curved structure and extends to the mounting plate;

[0007] It also includes:

[0008] The groove is formed on the steel sheet body and is used to form reinforcing ribs within the tire tread pattern;

[0009] The inclined surfaces are formed on both sides of the main body of the steel sheet.

[0010] As a further optimization of this utility model, the angle between the inclined plane and the horizontal plane is 10°-30°.

[0011] As a further optimization of this utility model, there are multiple grooves, which are evenly distributed on the top of the steel sheet body.

[0012] As a further optimization of this utility model, the mounting plate is provided with a plurality of positioning holes, which extend along the wavy curve of the mounting plate and are distributed in a wavy shape.

[0013] As a further optimization of this utility model, the mounting plate is provided with bent portions in opposite directions on both sides.

[0014] As a further optimization of this utility model, the edge of the bent portion is provided with a chamfer structure, and the chamfer angle is 30°-45°.

[0015] The beneficial effects of this utility model are as follows:

[0016] Unlike existing technologies, in actual operation, the tire's tear resistance is greatly improved by forming longitudinal reinforcing ribs on the tire tread through evenly distributed grooves on the steel sheet body. Secondly, the steel sheet body has inclined surfaces with a 10°-30° angle on both sides, which allows the rubber material and steel sheet to separate quickly during demolding, avoiding tread damage. At the same time, the connection between the two sides of the formed tread enhances the stability of the tread structure. Attached Figure Description

[0021] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0022] Example 1

[0023] like Figure 1 - Figure 3 As shown, a novel steel sheet for tire tread pressing includes a steel sheet body 1 and a mounting plate 2 disposed on the steel sheet body 1. The steel sheet body 1 has a wavy curved structure and extends to the mounting plate 2. The mounting plate 2 has bends 21 in opposite directions on both sides. Through the wavy curved structure, the tread rubber can be effectively promoted to flow evenly through periodic deformation during vulcanization. This ensures that the material distribution is uniform throughout the tire tread during molding, thereby improving the consistency and stability of the overall tire performance.

[0024] It also includes:

[0025] Groove 4 is formed on the steel sheet body 1 and is used to form reinforcing ribs within the tire tread pattern;

[0026] Inclined surface 11 is formed on both sides of the main body of steel sheet 1.

[0027] The angle between the inclined plane 11 and the horizontal plane is 10°-30°. This inclined structure facilitates rapid separation of the rubber compound and the steel sheet, greatly reducing the risk of tread damage and ensuring the integrity and aesthetics of the tire tread pattern. Moreover, the inclined design connects the two sides of the formed tread pattern, enhancing the structural stability of the tread pattern and improving the reliability of the tire during use.

[0028] There are multiple grooves 4, which are evenly distributed on the top of the steel sheet body 1, forming reinforcing ribs within the tire tread. These reinforcing ribs significantly enhance the tire's tear resistance, making the tire more durable when facing complex road conditions and frequent friction, greatly reducing tire damage caused by tread tears, and extending the tire's service life.

[0029] The mounting plate 2 has multiple positioning holes 3. The multiple positioning holes 3 extend along the wavy curve of the mounting plate 2 and are distributed in a wavy shape, so that the multiple positioning holes 3 are not on the same straight line, thereby preventing the steel sheet body 1 from being pulled out by the tire during demolding.

[0030] The edge of the bending part 21 is provided with a chamfer structure with a chamfer angle of 30°-45°, which not only enhances the mechanical engagement strength with the mold, but also extends the service life of the steel sheet through stress dispersion effect.

[0031] It should be noted that the working principle of a new type of steel sheet for tire tread pressing is as follows: The main body 1 of the steel sheet with a wavy curved structure is precisely fixed to the mold through the wavy positioning holes 3 on the mounting plate 2. During the pressing process, the grooves 4 evenly distributed on the surface of the main body 1 of the steel sheet form longitudinal reinforcing ribs on the tire tread to improve tear resistance. The inclined surface 11 with an angle of 10°-30° on both sides allows the rubber material to be quickly separated from the steel sheet during demolding, avoiding tread damage. At the same time, the two sides of the formed tread are connected to enhance the stability of the tread structure. The 30°-45° chamfer design of the reverse bending part 21 on both sides of the mounting plate 2 not only enhances the mechanical interlocking strength with the mold, but also extends the service life of the steel sheet through the stress dispersion effect. The entire wavy structure undergoes periodic deformation during vulcanization, making the tread rubber material flow more evenly, ultimately forming a high-performance tire tread with three-dimensional reinforcing ribs.

[0032] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
