[0002] The transfer ring clamping pad is an important component of the tire building machine. The transfer ring clamping pad in the prior art is usually composed of multiple pads, which have a certain gap between them when they are opened and clamped. Although this design can adapt to tire blanks of different sizes, during the tire blank forming process, due to the gap between the pads, the tread composite is subject to the shaping force at these positions without the restraint of the pads, which is prone to excessive extension and deformation, thereby affecting the true roundness of the tire blank and the uniformity of the final tire.

[0003] In addition, the gap between the pads makes it difficult to visually check the clamping roundness, which often requires the use of precision tools such as dial indicators to complete this process, adding additional operation time and cost. Utility Model Content

The pads can always maintain a true circle without gaps in the open and clamped states through a unique structural design, thereby ensuring that the tire blank obtains a uniform shaping force during the forming process, so as to solve the problem in the prior art that when the transfer ring clamps the tread composite part, there are gaps between the pads, resulting in uneven force on the tread composite part and reduced true roundness during the tire blank forming process.

[0005] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a tire forming machine transfer ring fully covers the clamping tile, including: a fixed tile; an elastic member arranged inside the fixed tile; and a movable tile movably connected to the inside of the fixed tile through the elastic member; wherein, when multiple groups of movable tiles on the fixed tiles are connected, they form a gapless circle for tire embryo molding.

[0006] Preferably, the inner arc surface of the movable tile and the inner arc surface of the fixed tile are located on the same curved surface.

[0007] Preferably, a slide groove matching the movable tile is provided on the inner side surface of the fixed tile.

[0008] Preferably, the movable tile comprises a left tile and a right tile; the left tile and the right tile are both slidably connected inside the slide groove via a guide member.

[0009] Preferably, the end of the left tile is configured as an arc-shaped convex structure, and the end of the right tile is configured as an arc-shaped concave structure.

[0010] Preferably, the elastic member includes at least two sets of compression springs, and the two sets of compression springs are installed at the end of the movable tile and one end of the chute.

[0011] Preferably, the guiding member includes: a guiding block fixed to the side of the movable tile; a guiding groove formed in the inner wall of the chute; wherein, the guiding block is movably connected inside the guiding groove.

[0012] Preferably, an installation groove is formed in the side surface of the guiding block, and a universal ball in contact with the inner wall of the chute is installed inside the installation groove.

[0013] Technical effects and advantages of the present utility model: A fully-covered clamping tile for a transfer ring of a tire forming machine proposed by the present utility model has the following advantages compared with the prior art:

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. The specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts belong to the scope of protection of the present invention.

[0024] The present invention provides a fully enclosed clamping block for a transfer ring of a tire forming machine, as Figure 1 shown, including: a fixed block 1, an elastic member 2 and a movable block 3.

[0025] In this embodiment, a slide groove 101 matching the movable block 3 is provided on the inner side of the fixed block 1, the elastic member 2 is arranged in the slide groove 101 inside the fixed block 1, and the movable block 3 is movably connected to the inside of the fixed block 1 through the elastic member 2. When the movable blocks 3 on multiple groups of fixed blocks 1 are butted, they form a gapless circle for the forming of the tire embryo, as Figure 6 and Figure 7 shown. In this embodiment, eight groups of fixed blocks 1 are provided.

[0026] Fixed block 1: The fixed block 1 is a component on the transfer ring, and a slide groove 101 is provided on its inner side for accommodating the movable block 3 and the elastic member 2.

[0027] Elastic member 2: The elastic member 2 (such as a spring) is located in the slide groove 101 and plays a role in adjusting the position of the movable block 3 to adapt to tire embryos of different diameters.

[0028] Movable block 3: The movable block 3 is connected to the fixed block 1 through the elastic member 2 and can adjust its position according to the diameter of the tire embryo to ensure that the entire transfer ring is in a true circular state.

[0029] When the transfer ring needs to hold an embryo with a larger diameter, the elastic member 2 (such as a spring) will push the movable block 3 outward. At this time, there is a certain gap between the movable block 3 and the fixed block 1. When the transfer ring holds an embryo with a smaller diameter, the mutual force between the movable block 3 and the adjacent fixed block 1 will cause the elastic member 2 (such as a spring) to contract, thereby reducing the distance between the movable block 3 and the fixed block 1 until the movable block 3 is in close contact with the adjacent fixed block 1, forming a true circular state without gaps.

[0030] The all-round covering and clamping block of the transfer ring of the present utility model can ensure uniform force on the embryo during the forming process, effectively improve the true roundness of the embryo, thereby enhancing the uniformity of the tire and reducing the jitter, noise and abnormal wear generated during the use of the tire. The design of the mutual engagement between the movable block 3 and the fixed block 1 through the semi-circular protrusion and the semi-circular groove facilitates visual inspection of the clamping roundness, simplifies the inspection process, reduces the time required for inspection with a dial indicator, and improves production efficiency. The all-round covering design reduces the risk of the tread composite falling off during the clamping process, further improving the quality and yield rate of the tire.

[0031] Through the above improvements, the present utility model effectively solves the problems existing in the clamping block of the transfer ring in the prior art, and improves the efficiency and product quality during the tire forming process.

[0032] As Figure 5 shown, in a further preferred embodiment, the inner arc surface of the movable block 3 and the inner arc surface of the fixed block 1 are on the same curved surface. The inner arc surface of the movable block 3 and the inner arc surface of the fixed block 1 being on the same curved surface enables the embryo to always be in a stable environment during the forming process, avoiding local over-extension caused by gaps between the blocks and ensuring the true roundness of the embryo.

[0033] In a further preferred embodiment, the movable block 3 includes a left block 301 and a right block 302; both the left block 301 and the right block 302 are slidably connected inside the chute 101 through a guiding member 4. Further, the end of the left block 301 is provided with an arc-shaped convex structure, and the end of the right block 302 is provided with an arc-shaped concave structure, and the two cooperate with each other to form a complete circular contour.

[0034] Specifically, the left segment 301 and the right segment 302 are engaged with each other through a semi-circular protrusion and a semi-circular groove, which facilitates visual inspection of the clamping roundness, simplifies the inspection process, reduces the time required for inspection using a dial indicator, and improves production efficiency. The fully enclosed design reduces the risk of the tread composite falling off during clamping, further improving the quality and yield rate of the tire. The ends of the left segment 301 and the right segment 302 are cooperated with each other through an arc-shaped protrusion structure and an arc-shaped concave structure, ensuring that the tire blank is always in a stable environment during the molding process, avoiding local excessive extension caused by gaps between the segments, and ensuring the true roundness of the tire blank.

[0035] As Figure 3 shown, in a further preferred embodiment, the elastic member 2 includes at least two sets of compression springs 201. The two sets of compression springs 201 are installed at the end of the movable segment 3 and one end of the chute 101 for adjusting the position of the movable segment 3 to adapt to tire blanks of different diameters.

[0036] Specifically, the use of the two sets of compression springs 201 ensures the smooth sliding of the movable segment 3 in the chute 101, improves the accuracy of the clamping segment during operation, and is beneficial to maintaining the true round state of the transfer ring clamping segment.

[0037] The use of the guiding member 4 ensures the smooth sliding of the movable segment 3 in the chute 101, improves the accuracy of the clamping segment during operation, and is beneficial to maintaining the true round state of the transfer ring clamping segment.

[0038] As Figure 4 shown, in a further preferred embodiment, the guiding member 4 includes: a guiding block 401 fixed to the side of the movable segment 3; a guiding groove 402 formed in the inner wall of the chute 101; wherein, the guiding block 401 is movably connected to the inside of the guiding groove 402.

[0039] Specifically, the guiding block 401: The guiding block 401 is fixed to the side of the movable segment 3, which plays a role in guiding the smooth movement of the movable segment 3 along the chute 101. The guiding groove 402 is formed in the inner wall of the chute 101 and cooperates with the guiding block 401 to ensure that the movable segment 3 does not deviate from the predetermined path during the sliding process.

[0040] In some other embodiments, an installation groove 403 is formed in the side surface of the guiding block 401, and a universal ball 404 in contact with the inner wall of the chute 101 is installed inside the installation groove 403.

[0041] Specifically, an installation groove 403 is formed on the side of the guiding block 401. A universal ball 404 in contact with the inner wall of the sliding groove 101 is installed inside the installation groove 403. The universal ball 404 can reduce the friction between the guiding block 401 and the inner wall of the sliding groove 101, improve the smoothness of the sliding of the guiding block 401, ensure that the movable segment 3 slides more smoothly during the sliding process, and thus improve the reliability and service life of the overall system.

[0042] The specific usage process of a transfer ring full-coverage clamping segment for a tire building machine includes the following steps:

[0043] Preparation stage: Ensure that all components (fixed segment 1, movable segment 3, elastic member 2, guiding member 4 and its universal ball 404) have been correctly installed on the transfer ring. Check whether the movable segment 3 can slide freely, and confirm that the elastic member 2 (such as compression spring 201) is in a normal working state.

[0044] Preset diameter: According to the diameter of the tire blank to be processed, preset the diameter size of the transfer ring. When setting the diameter, the compression spring 201 adjusts the position of the movable segment 3 according to the set value to ensure that the segments can form a gapless circle at the set diameter.

[0045] Place the tread composite: Place the tread composite on the transfer ring so that it is located at the center of the transfer ring.

[0046] Clamping process: When the clamping diameter of the transfer ring is larger, the compression spring 201 is compressed, and the movable segment 3 is pushed away from the fixed segment 1 to form a certain gap. When the clamping diameter of the transfer ring is smaller, the mutual force between the movable segment 3 and the fixed segment 1 causes the compression spring 201 to rebound, and the movable segment 3 approaches the fixed segment 1 until there is no gap between the segments, forming a closed true circle.

[0047] Tire blank forming: Under the clamped state of the transfer ring, the tread composite is subjected to uniform pressure during the tire blank forming process to ensure the roundness of the tire blank. The inner arc surface of the movable segment 3 and the inner arc surface of the fixed segment 1 are on the same curved surface to ensure that the tire blank is uniformly stressed during the forming process.

[0048] Check roundness: Check the alignment between the clamping segments by visual inspection to judge the clamping roundness of the transfer ring. If more accurate measurement is required, after a preliminary visual inspection, a dial indicator can be used for precise calibration.

[0049] Release the tire blank: After the forming is completed, release the transfer ring and take out the tire blank.

[0050] This application is conducive to improving the true roundness of the tire embryo: The transfer ring of the present utility model completely wraps the clamping tile, which can ensure uniform force on the tire embryo during the forming process, effectively improve the true roundness of the tire embryo, thereby enhancing the uniformity of the tire and reducing the jitter, noise, and abnormal wear generated during the use of the tire.

[0051] Improve production efficiency: The left tile 301 and the right tile 302 are designed to be engaged with each other through semi-circular protrusions and semi-circular grooves, which is convenient for visually inspecting the clamping roundness, simplifies the inspection process, reduces the time required for inspection using a dial indicator, and improves production efficiency.

[0052] Enhance clamping stability: The fully wrapped design reduces the risk of the tread composite falling off during the clamping process, further improving the quality and yield rate of the tire.

[0053] Optimize the tire embryo forming environment: The inner arc surfaces of the movable tile 3 and the fixed tile 1 are on the same curved surface, so that the tire embryo is always in a stable environment during the forming process, avoiding local excessive extension caused by gaps between the tiles, and ensuring the true roundness of the tire embryo.

[0054] Improve clamping accuracy: The use of the guide member 4 ensures the smooth sliding of the movable tile 3 in the chute 101, improves the accuracy of the clamping tile during the working process, is conducive to maintaining the true round state of the transfer ring clamping tile, and further enhances the stability and reliability during the clamping process.

[0055] Reduce friction: By installing a universal ball 404 in the installation groove 403 of the guide block 401, the friction between the guide block 401 and the inner wall of the chute 101 can be significantly reduced, improving the smoothness and guiding accuracy of the sliding of the guide block 401, ensuring that the movable tile 3 slides more smoothly, and thus improving the reliability and service life of the overall system.

[0056] Through the above improvements, the present utility model effectively solves the problems existing in the transfer ring clamping tile of the prior art and improves the efficiency and product quality during the tire forming process.

[0057] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model.
