Description

Technical Field

[0001] The present application relates to the field of tires, and in particular to an improved tire bead device. Background Art

[0002] Tires are circular elastic rubber products that roll on the ground and are installed on various vehicles or machines. They are usually installed on metal rims, can support the vehicle body, buffer external impacts, achieve contact with the road surface and ensure the driving performance of the vehicle. Tires are often used under complex and harsh conditions. They are subjected to various deformations, loads, forces, and high and low temperature effects when driving, so they must have high load-bearing performance, traction performance, and buffering performance. At the same time, they are also required to have high wear resistance and flex resistance, as well as low rolling resistance and heat generation.

[0003] Therefore, the stability of the bead wire has a great impact on the service life of the tire. The bead wire of the current single bead equipment is arranged in a square shape, which is easily deformed due to extrusion during the tire forming process. In order to make up for this deficiency, the bead can be changed to a hexagonal structure, which is more stable. This requires us to put forward new requirements for the bead winding equipment (Former).

[0004] The mouth of the existing tire bead wire winding equipment is a trapezoidal structure, such as Figure 1 and Figure 2 As shown, the bead wires 3 are arranged in 4 rows, with a maximum number of 5, for example. The bead wires 3 of the second layer are easily deviated from their original positions during winding, and it is not easy to maintain the hexagonal shape. Therefore, the disadvantage of this mouth shape is that the longest part of the hexagon is easy to be scattered and cannot maintain the shape we need, which makes the hexagonal bead wire poor in stability during winding, so that the bead wire cannot form a perfect hexagon and cannot be directly applied to tires. Utility Model Content

[0005] In order to make up for the above shortcomings, the present application provides an improved tire bead equipment, which aims to improve the problem that the longest part of the hexagon is easy to fall apart and cannot maintain the shape we need, thereby making the hexagonal tire bead wire have poor stability during winding, making it impossible for the tire bead wire to form a perfect hexagon and cannot be directly applied to the tire.

[0006] An embodiment of the present application provides an improved tire bead device, including a winding model.

[0007] A placement cavity with an open top is arranged inside the winding model, and the placement cavity is a hexagonal structure.

[0008] In a specific embodiment, the winding model includes a first trapezoidal portion at the bottom and a second trapezoidal portion integrally formed with the top of the first trapezoidal portion, the first trapezoidal portion is narrow at the bottom and wide at the top, and the second trapezoidal portion is wide at the bottom and narrow at the top, so that the first trapezoidal portion and the second trapezoidal portion turn the placement cavity into a hexagon.

[0009] In a specific embodiment, a plurality of tire bead wires are arranged inside the placement cavity.

[0010] In a specific embodiment, a plurality of the bead wires form a hexagon.

[0011] In a specific embodiment, it also includes a tire bead wire winding base, and a plurality of the winding models are equidistantly installed on the tire bead wire winding base.

[0012] Beneficial effect: This technical solution is only for equipment using the single bead winding method. By changing the placement cavity into a hexagonal shape that matches the tire bead wire, the tire bead wire can more easily maintain a hexagonal shape during winding, thereby preventing the hexagonal bead wire from unravelling at the longest part during winding, thereby improving the stability of the tire bead wire during winding, improving the stability of the tire bead wire when used inside the tire, and thereby increasing the service life of the tire bead.

[0019] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0020] See also Figure 1-Figure 4 The present application provides an improved tire bead device, including a winding model 2.

[0021] See also Figure 3 and Figure 4 The winding model 2 is provided with a placement cavity 4 with an open top, and the placement cavity 4 is a hexagonal structure. In this application, the technical solution is only for the equipment of the single bead winding method, and by changing the placement cavity 4 into a hexagonal shape that matches the bead wire 3, the bead wire 3 is easier to maintain the hexagonal shape during winding, thereby preventing the longest part of the hexagonal bead wire from being difficult to spread during winding, thereby improving the stability of the bead wire 3 during winding, improving the stability of the bead wire 3 when applied to the tire, and thereby improving the service life of the bead.

[0022] In this embodiment, the winding model 2 includes a first trapezoidal portion 5 at the bottom and a second trapezoidal portion 6 integrally formed with the top of the first trapezoidal portion 5. The first trapezoidal portion 5 is narrow at the bottom and wide at the top, and the second trapezoidal portion 6 is wide at the bottom and narrow at the top, so that the first trapezoidal portion 5 and the second trapezoidal portion 6 transform the placement cavity 4 into a hexagon. Among them, by setting the first trapezoidal portion 5 and the second trapezoidal portion 6, the row with the largest number of bead wires 3 is located at the intersection of the first trapezoidal portion 5 and the second trapezoidal portion 6, thereby preventing the row with the largest number of bead wires 3 from being easily scattered.

[0023] In this embodiment, the specific height and width of the first trapezoidal portion 5 and the second trapezoidal portion 6 inside the winding model 2 can be set in multiple sizes according to the size of the hexagon formed by the tire bead wire 3, and then the corresponding winding model 2 is selected when making hexagonal tire bead wires 3 of different specifications.

[0024] In this embodiment, a plurality of bead wires 3 are arranged inside the placement cavity 4. The plurality of bead wires 3 form a hexagon. The hexagon formed by the bead wires 3 increases the stability of the bead.

[0025] In this embodiment, a bead wire winding base 1 is further included, and a plurality of winding models 2 are equidistantly installed on the bead wire winding base 1. Multiple groups of bead wires 3 can be wound and formed at the same time.

[0026] Working principle of the improved tire bead equipment:

[0027] In the present application, the technical solution is only for the equipment of the single bead winding method. By changing the placement cavity 4 into a hexagonal shape that matches the tire bead wire 3, the tire bead wire 3 can more easily maintain the hexagonal shape during winding, thereby preventing the longest part of the hexagonal bead wire from spreading out during winding, thereby improving the stability of the tire bead wire 3 during winding, improving the stability of the tire bead wire 3 when applied inside the tire, and thereby increasing the service life of the tire bead.
