Description

Technical Field

[0001] This utility model relates to the field of tire manufacturing equipment technology, and specifically to a forming machine transfer ring that improves tire gripping. Background Technology

[0002] In tire manufacturing, transfer rings are used to grip and transfer green tires. Existing transfer rings typically employ a ring structure composed of six rectangular grippers, driven radially by a cylinder rod. However, due to the inherent shape limitations of the rectangular grippers, gaps inevitably exist between adjacent grippers when they contract to form a ring and grip the circular cross-section of the green tire. These gaps result in a small and uneven contact area between the grippers and the circumference of the green tire, leading to discontinuous gripping force distribution. When gripping and pressing the green tire, this can easily cause localized deformation or dents. This deformation directly affects subsequent processes, leading to decreased uniformity in the finished tires and ultimately a lower tire manufacturing yield. A lower yield means more defective products, which typically must be discarded. This not only wastes raw materials and energy but also increases waste disposal costs, significantly driving up the company's production costs.

[0003] Therefore, how to provide a forming machine transfer ring that improves tire gripping and solves the defects in the structure of existing tire manufacturing equipment is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0004] Therefore, this utility model provides a forming machine transfer ring that improves tire gripping, in order to solve the problems in the prior art where the inherent gaps in the rectangular gripper structure lead to a small contact area for tire gripping, uneven force distribution, and consequently, deformation of the green tire, reduced tire uniformity, and lower pass rate.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] This utility model discloses a forming machine transfer ring for improving tire gripping, comprising:

[0007] A plurality of first tire grippers are arranged in a concentric circumferential array, with adjacent first tire grippers fitted together.

[0008] Two second tire clamps are circumferentially arranged on both sides of the adjacent first tire clamps in a concentric structure. One second tire clamp is fitted into the first tire clamp, and the other second tire clamp is spaced apart from the first tire clamp.

[0009] The third tire clamp is positioned between the two second tire clamps.

[0010] In one possible implementation, the first tire clamp, the second tire clamp, and the third tire clamp are all T-shaped and each includes:

[0011] The claw arm has a gripping part installed at one end;

[0012] A round hole is formed on the side wall of the claw arm;

[0013] A through hole is formed on the side wall of the gripping part.

[0014] In one possible implementation, the gripping part has small spikes on one side wall facing the center.

[0015] In one possible implementation, the first tire gripper further includes:

[0016] A first extension plate is installed at one end of the gripping part;

[0017] A slot is provided at the other end of the gripping part.

[0018] In one possible implementation, the second tire gripper further includes a second extension plate mounted at one end of the gripping portion.

[0019] In one possible implementation, the number of first tire grippers is set to N, where 1 ≤ N ≤ 3.

[0020] This utility model has the following advantages:

[0021] This invention innovatively replaces the original rectangular grippers with multiple T-shaped tire grippers. The core of this design lies in the unique geometric structure of the T-shaped grippers, which allows adjacent grippers to precisely interlock. This interlocking structure fundamentally eliminates the inherent gaps between traditional rectangular grippers, significantly increasing the actual contact area with the circumference of the green tire. Simultaneously, the circular holes and through holes on the gripper arms connect to the cylinder rod, ensuring that all grippers undergo radial contraction or expansion under cylinder drive, resulting in a synchronized and non-interfering effect, ultimately forming a uniform and tightly fitting circular gripping profile. Furthermore, small spikes on the inner side of the gripping section further enhance the reliability and anti-skid performance. The synergistic effect of these key components effectively solves the problem of localized deformation of the green tire caused by small contact area and uneven force distribution, significantly improving the uniformity and manufacturing pass rate of the finished tire.

[0029] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0030] Please refer to Figures 1-4 The present invention discloses a tire gripping forming machine transfer ring, which consists of three parts, as follows: Figure 1 It includes a first tire clamp 1, a second tire clamp 2 and a third tire clamp 3. A plurality of first tire clamps 1 are arranged in a concentric circumferential array, and adjacent first tire clamps 1 are fitted together. Two second tire clamps 2 are arranged in a concentric circumferential array on both sides of adjacent first tire clamps 1. One second tire clamp 2 is fitted together with a first tire clamp 1, and the other second tire clamp 2 is spaced apart from the first tire clamp 1. The third tire clamp 3 is disposed between the two second tire clamps 2.

[0031] In use, the cylinder rod retracts towards the center, synchronously driving the first tire gripper 1, the second tire gripper 2, and the third tire gripper 3 to move towards the axis at the same speed. During this movement, adjacent first tire grippers 1 engage and interlock with each other, and the first second tire gripper 2 engages and interlocks with its adjacent first tire gripper 1. A gap is left between the second second tire gripper 2 and its adjacent first tire gripper 1, and a gap is left between the second second tire gripper 2 and the third tire gripper 3. These gaps serve as process channels, and their position and size are adapted to the working requirements of the tire forming machine's pressure rollers, accommodating and avoiding the tire shoulder pressure roller, tread pressure roller, and tread roll. The rotating pressure roller ensures no mechanical interference when retracted to its minimum state, forming a circular profile. When the first tire gripper 1, the second tire gripper 2, and the third tire gripper 3 simultaneously contact the green tire surface and reach the preset pressure, the pressure sensor sends a real-time feedback signal to the cylinder. The cylinder immediately stops retracting. After the green tire transfer is completed, the cylinder rod expands outward, and the first tire gripper 1, the second tire gripper 2, and the third tire gripper 3 simultaneously separate and reset, releasing the tire. This avoids the problems caused by the inherent gaps in the rectangular gripper structure, which result in a small tire gripping contact area, uneven force, and consequently, green tire deformation, decreased tire uniformity, and reduced pass rate.

[0032] In a specific embodiment, such as Figure 2 The first tire gripper 1, the second tire gripper 2, and the third tire gripper 3 are all T-shaped and each includes: a gripper arm 101, a gripping part 102, a small spike 1024, a round hole 103, and a through hole 104. The gripping part 102 is installed at one end of the gripper arm 101. The round hole 103 is formed on the side wall of the gripper arm 101, and the through hole 104 is formed on the side wall of the gripping part 102. The T-shaped design of the first tire gripper 1, the second tire gripper 2, and the third tire gripper 3 provides a physical basis for their interlocking. The width of the gripping part 102 allows it to cover part of the area of ​​adjacent grippers, thus significantly reducing the straight gaps between traditional rectangular grippers, increasing the effective gripping area, and making the gripping force more evenly distributed. The gripper arm 101 provides radial motion support force, driving the tire gripper assembly to extend or retract towards the axis. The circumferential width of the gripping part 102 is sufficient to cover the area between adjacent gripper arms 101, increasing its actual contact area with the green tire. The round hole 103 and the through hole 104 serve as the connection ports between the tire gripper assembly and the drive mechanism. The tire gripper 1 is connected to the cylinder telescopic rod by bolts or pins passing through these holes.

[0033] In a specific embodiment, such as Figure 2 The gripping part 102 has small spikes 1024 on the side surface facing the circumferential axis. The small spikes 1024 serve as an auxiliary measure to enhance the friction between the gripper and the surface of the green tire, prevent slippage and fall-off during gripping and transfer, and improve the reliability of gripping.

[0034] In a specific embodiment, such as Figure 3 The first tire gripper 1 also includes a first extension plate 111 and a slot 112. The first extension plate 111 is installed at one end of the gripping part 102, and the slot 112 is formed at the other end of the gripping part 102. The first extension plate 111 is a plate-shaped structure that protrudes from the gripping part 102 in the circumferential direction, and the slot 112 is a groove-shaped structure that is recessed in the gripping part 102 in the circumferential direction. When multiple first tire grippers 1 are arranged adjacent to each other, the first extension plate 111 of one first tire gripper 1 will be inserted into the slot 112 of the adjacent first tire gripper 1, forming an interlocking effect to ensure that the ends do not interfere with each other when retracting.

[0035] In a specific embodiment, such as Figure 4 The second tire gripper 2 also includes a second extension plate 201, which is installed at one end of the gripping part 102. The function of the second extension plate 201 is similar to that of the first extension plate 111, which is to be inserted into the corresponding interface of the adjacent gripper. The second extension plate 201 slides in the slot 112 of the adjacent gripper to prevent it from colliding and interfering with the adjacent gripper at the end of the retraction.

[0036] In a specific embodiment, the number of first tire grippers 1 is set to N, where 1 ≤ N ≤ 3. The number of first tire grippers 1 is limited to 1 to 3, and their core function is to ensure that the T-shaped grippers dynamically improve gripping stability through the interlocking structure when retracting, while avoiding motion interference and adapting to the gripping needs of different tire specifications.

[0037] Although the present invention has been described in detail above with general descriptions and specific embodiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
