Description

Technical Field

[0001] This utility model relates to the field of tire processing, and more specifically, to a transfer ring and a forming machine. Background Technology

[0002] During operation, the transfer ring clamps tires of different diameters by controlling the radial expansion and contraction of the bearing blocks. During this expansion and contraction, due to factors such as the bearing blocks' own weight and installation errors, misalignment between the bearing blocks and the tires can occur, leading to tire deformation during clamping and, in severe cases, even tire drop. Currently, most transfer rings have fixed guide rods or rails installed on the bearing blocks to improve concentricity during expansion and contraction. However, this type of guide device, because it always maintains the same angle with the bearing blocks, has a generally poor guiding effect. Furthermore, the guide device requires high machining precision and is difficult to install. Utility Model Content

[0003] The main objective of this invention is to provide a transfer ring and a forming machine to solve the problem of poor concentricity between the tiles of the transfer ring and the mold cylinder during the expansion and contraction process in the prior art.

[0004] To achieve the above objectives, according to one aspect of the present invention, a transfer ring is provided, comprising: a ring body, a plurality of tiles for clamping the tire cylinder, and a plurality of guide assemblies, wherein the tiles are arranged circumferentially along the ring body and are capable of moving radially along the ring body; the guide assemblies are disposed between two adjacent tiles, wherein one end of the guide assembly is rotatably connected to one tile and the other end of the guide assembly is slidably connected to the other tile.

[0005] Furthermore, each end of the tile has a first mounting seat and a second mounting seat. In two adjacent tiles, the first mounting seat of one tile and the second mounting seat of the other tile are close to each other. One end of the guide assembly is rotatably connected to the first mounting seat, and the other end of the guide assembly is slidably inserted into the second mounting seat.

[0006] Furthermore, the guide assembly includes a guide rod and a guide seat, the guide seat being rotatably connected to the first mounting base via a pivot, one end of the guide rod being connected to the guide seat, and the other end of the guide rod passing through the second mounting base.

[0007] Furthermore, the second mounting base has a through hole, in which the guide rod passes, and the axis of the through hole is perpendicular to the axis of the ring body.

[0008] Furthermore, the length of the guide rod is greater than the maximum separation distance between the first and second mounting seats at the adjacent ends of the adjacent tiles.

[0009] Furthermore, the transmission ring also includes a drive ring and multiple connecting rods. The drive ring is coaxially arranged with the ring body and is rotatable relative to the ring body. Each connecting rod is arranged circumferentially along the drive ring. The connecting rods are movably connected to the tiles, and the drive ring is driven by the connecting rods. When the drive ring rotates, it drives each tile to move radially along the ring body through each connecting rod.

[0010] Furthermore, the connecting rod also includes an intermediate connecting part, which is located between the two ends of the connecting rod and is rotatably connected to the ring body.

[0011] Furthermore, the drive ring also includes multiple adjustment components. The two ends of the adjustment components are connected to the drive ring and the connecting rod, respectively. The connecting rod is connected to the drive ring through the adjustment components, and the length of the adjustment components can be adjusted.

[0012] Furthermore, the adjustment assembly includes: a connector and a plurality of adjusting members, the connector having a first threaded hole and a second threaded hole at both ends, the first threaded hole and the second threaded hole having opposite directions of rotation; both ends of the connector are connected to adjusting members, and the adjusting members are threadedly connected to the connector.

[0013] According to another aspect of the present invention, a molding machine is provided, including the aforementioned transfer ring.

[0014] By applying the technical solution of this utility model, a guide component is positioned between two adjacent tiles, with one end of the guide component rotatably connected to one of the tiles. This allows the angle of the guide component relative to the tiles to be adjustable, enabling it to flexibly adjust its angle according to the expansion and contraction of the tiles. This improves the concentricity between the tiles and between the tiles and the tire barrel, preventing inconsistent expansion and contraction at both ends of the tiles due to the guide component. Consequently, when the transfer ring clamps the tire barrel, each tile can make uniform contact with the outer periphery of the tire barrel, reducing damage to the tire barrel and improving the reliability of the transfer ring clamping the tire barrel. Furthermore, the movable connection at both ends of the guide component helps reduce the machining precision and installation difficulty of the guide component itself, thereby reducing processing costs and installation complexity.

[0022] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0024] To address the problem of poor concentricity between the tiles of the transfer ring and the die cylinder during the expansion and contraction process in the prior art, this utility model provides a transfer ring and a forming machine, wherein the forming machine includes the transfer ring described below.

[0025] like Figures 1 to 3 The transmission ring shown includes: a ring body 10, a plurality of clamping blocks 20 for holding the tire tube, and a plurality of guide assemblies 30. The blocks 20 are arranged circumferentially along the ring body 10 and are capable of moving radially along the ring body 10. The guide assembly 30 is disposed between two adjacent blocks 20. In two adjacent blocks 20, one end of the guide assembly 30 is rotatably connected to one block 20, and the other end of the guide assembly 30 is slidably connected to the other block 20.

[0026] In this embodiment, the guide component 30 is positioned between two adjacent tiles 20, and one end of the guide component 30 is rotatably connected to one of the tiles 20. This allows the angle of the guide component 30 relative to the tiles 20 to be adjustable, enabling the guide component 30 to flexibly adjust its angle according to the expansion and contraction of the tiles 20. This improves the concentricity between the tiles 20 and between the tiles 20 and the tire barrel, preventing inconsistent expansion and contraction at both ends of the tiles 20 due to the action of the guide component 30. As a result, when the transfer ring clamps the tire barrel, each tile 20 can make uniform contact with the outer periphery of the tire barrel, thereby reducing damage to the tire barrel and improving the reliability of the transfer ring clamping the tire barrel. At the same time, the guide component 30 has movable connections at both ends, which helps to reduce the machining precision and installation difficulty of the guide component 30 itself, thereby reducing processing costs and installation complexity.

[0027] In this embodiment, each end of the tile 20 has a first mounting base 21 and a second mounting base 22. In two adjacent tiles 20, the first mounting base 21 of one tile 20 and the second mounting base 22 of the other tile 20 are close to each other. One end of the guide component 30 is rotatably connected to the first mounting base 21, and the other end of the guide component 30 is slidably inserted into the second mounting base 22. This ensures that the guide component 30 can be stably connected to the tile 20, while allowing the guide component 30 to have a certain degree of rotation and sliding freedom to adapt to the positional changes of the tile 20 during radial movement. Specifically, two adjacent tiles 20 are arranged circumferentially along the ring body 10, so the first mounting base 21 and the second mounting base 22 are also arranged circumferentially along the ring body 10, thereby enabling multiple guide components 30 to be arranged circumferentially along the ring body 10. The first mounting base 21 can be configured as two opposing and spaced mounting plates, with the mounting plates extending circumferentially along the arc where the tile 20 is located. The second mounting base 22 can be configured with the same structure, with the end of the guide component 30 positioned between the two opposing mounting plates to enable the guide component 30 to rotate or slide. When the pads 20 move away from the center of the ring 10, one end of each guide component 30 located on the second mounting base 22 moves circumferentially towards the adjacent pad 20 along the ring 10. This increases the length of the guide component 30 between the first mounting base 21 and the second mounting base 22 to accommodate the increased diameter of the circumference of each pad 20. The end of each guide component 30 connected to the first mounting base 21 rotates around the first mounting base 21. Thus, as the circumference of the pad 20 increases, the extension direction of the guide component 30 remains perpendicular to the radial direction of the circumference, preventing the center of the circumference at both ends of the pad 20 from being inconsistent with the center of the tire tube. This ensures the concentricity of the pads 20 during expansion and contraction, reducing damage to the tire tube. The motion principle when the pads 20 move towards the center of the ring 10 is the same as when they move away from the center of the ring 10, and will not be repeated here.

[0028] In this embodiment, the guide assembly 30 includes a guide rod 31 and a guide seat 32. The guide seat 32 is rotatably connected to the first mounting base 21 via a rotating shaft. One end of the guide rod 31 is connected to the guide seat 32, and the other end of the guide rod 31 passes through the second mounting base 22, thereby ensuring the stability and concentricity of the tile 20 during expansion and contraction, reducing the deformation of the tire during clamping, and improving transmission efficiency. Specifically, in this embodiment, the guide assembly 30 is provided with a guide seat 32 at one end near the first mounting base 21. Mounting holes can be provided on both mounting plates of the first mounting base 21, with the mounting holes facing each other. A rotating shaft is provided between the two mounting holes. The guide seat 32 can be sleeved on the guide rod 31, and a through hole is provided on the guide seat 32 near the rotating shaft. The through hole is sleeved on the rotating shaft, thereby allowing it to rotate relative to the rotating shaft. In this way, the guide seat 32 is connected to the first mounting seat 21 via a rotating shaft, thereby allowing the guide seat 32 to rotate relative to the tile 20, while the sliding of the guide rod 31 relative to the second mounting seat 22 can adapt to the positional changes of the tile 20 during radial movement. Of course, the structure of the first mounting seat 21 is not limited to this; elastic materials such as spring sheets can also be used to realize the swing of the guide assembly 30.

[0029] Preferably, the axis of the rotating shaft is perpendicular to the axis of the guide rod 31 and parallel to the axis of the ring 10, so that the axis of the guide rod 31 can be perpendicular to the axial direction of the ring 10, that is, the axis of the guide rod 31 can be along the tangent of the circumference of each guide rod 31, thereby ensuring the concentricity between each tile 20 to ensure reliable clamping of the tire cylinder.

[0030] In this embodiment, the second mounting base 22 has a through hole, and the guide rod 31 passes through the through hole. The axial direction of the through hole is perpendicular to the axial direction of the ring body 10, thereby allowing the guide rod 31 to slide within the through hole while restricting the lateral movement of the guide rod 31, ensuring the linear movement of the guide rod 31, thus improving the movement accuracy of the guide rod 31, ensuring the stability and concentricity of the pad 20 during the expansion and contraction process, and reducing damage to the tire cylinder during clamping. Specifically, as... Figure 2 As shown, the second mounting base 22 in this embodiment is configured as an annular structure, extending circumferentially along the arc where the tile 20 is located. A through hole is provided inside the annular structure for the guide assembly 30 to pass through. One end of the guide rod 31, away from the first mounting base 21, passes through the second mounting base 22. After the guide rod 31 passes through the second mounting base 22, a limiting member can be provided on the side of the second mounting base 22 away from the first mounting base 21 adjacent to the tile 20. The limiting member can be a protrusion located on the surface of the guide rod 31 to prevent the guide member from detaching from the side of the second mounting base 22 away from the first mounting base 21 adjacent to the tile 20, thereby ensuring the safety and reliability of the guide assembly 30.

[0031] In this embodiment, the length of the guide rod 31 is greater than the maximum separation distance between the first mounting base 21 and the second mounting base 22 at the adjacent ends of the adjacent tire blocks 20. This ensures that the guide rod 31 can always connect the two adjacent tire blocks 20 within the maximum expansion and contraction range of the tire blocks 20, thus providing a stable guiding effect at any position. This improves the stability and reliability of the tire blocks 20 during expansion and contraction, ensuring the safety and efficiency of the tire barrel during the transfer process. Specifically, the guide rod 31 in this embodiment is cylindrical, and the end of the guide rod 31 away from the guide seat 32 can slide within the second mounting base 22. This adjusts the length of the guide rod 31 between the two adjacent tire blocks 20, so that when clamping tire barrels of different diameters, the guide rod 31 can adjust its length between the two adjacent tire blocks 20 according to the expansion and contraction of the tire blocks 20, thereby effectively improving the adaptability and flexibility of the transfer ring.

[0032] In this embodiment, the transmission ring further includes a drive ring 40 and multiple connecting rods 50. The drive ring 40 is coaxially arranged with the ring body 10 and is rotatably arranged relative to the ring body 10. Each connecting rod 50 is arranged circumferentially along the drive ring 40 and is movably connected to the tile 20. The drive ring 40 is drivenly connected to the connecting rods 50. When the drive ring 40 rotates, each tile 20 is driven to move radially along the ring body 10 through each connecting rod 50. Thus, the drive ring 40 is used as the power transmission center, and the power is evenly distributed to each tile 20 through the connecting rods 50 to realize the radial movement of the tile 20. Specifically, in this embodiment, the ring body 10 is annular, and the drive ring 40 is set as an annular ring coaxial with the ring body 10. The two ends of the connecting rod 50 are movably connected to the drive ring 40 and the pad 20, respectively. When the drive ring 40 rotates, it can drive all the connecting rods 50 to move synchronously, thereby driving all the pads 20 to move synchronously, ensuring that all the pads 20 are always located on the same circumference. This improves the power transmission efficiency of the transmission ring and the consistency of the pad 20's movement, ensuring the stability and safety of the tire during transmission. The movable connection between the pads 20 and the connecting rods 50 allows the positional relationship between the pads 20 and the connecting rods 50 to automatically adjust according to the diameter of the circle containing each pad 20 when the drive ring 40 drives the connecting rods 50 to rotate. This avoids the concentricity difference of the pads 20 caused by the constant angle of the pads 20 relative to the connecting rods 50, thereby improving the motion coordination of the connecting rods 50 and the response speed of the pads 20, ensuring the smoothness and efficiency of the tire during transmission. Similarly, the movable connection between the connecting rod 50 and the drive ring 40 allows the angle between the connecting rod 50 and the drive ring 40 to change when the drive ring 40 drives the connecting rod 50 to move, thereby adapting to the clamping of tires of different diameters.

[0033] In this embodiment, the connecting rod 50 further includes an intermediate connecting portion 51, which is located between the two ends of the connecting rod 50 and is rotatably connected to the ring body 10. By providing a rotatable intermediate connecting portion 51 in the middle of the connecting rod 50, the connecting rod 50 can adapt to the movement trajectory of the ring body 10 while driving the tile 20 to move, thus increasing the degree of freedom of movement of the connecting rod 50 and enabling radial movement of the tile 20. Specifically, as... Figure 1 , Figure 2 As shown, the connecting rod 50 in this embodiment is shaped like the number "7". That is, the connecting rod 50 includes a first segment and a second segment that is longer than the first segment. The end of the first segment away from the second segment is connected to the drive ring 40, and the end of the second segment away from the first segment is connected to the tile 20. The first segment and the second segment are bent and connected, and the bend has an intermediate connecting part 51. A rotating shaft can be provided at the intermediate connecting part 51. The intermediate connecting part 51 is connected to the ring body 10 through the rotating shaft. So when the drive ring 40 drives the connecting rod 50 to rotate, the connecting rod 50 can rotate around the intermediate connecting part 51, thereby causing the end of the second segment away from the first segment to generate a radial displacement along the ring body 10, thereby realizing the radial expansion and contraction of the tile 20.

[0034] In this embodiment, the drive ring 40 further includes multiple adjustment components 60. The two ends of each adjustment component 60 are connected to the drive ring 40 and the connecting rod 50, respectively. The connecting rod 50 is connected to the drive ring 40 via the adjustment components 60, and the length of the adjustment components 60 is adjustable. This helps to further improve the concentricity between the tiles 20 and reduces assembly difficulty. Specifically, as... Figure 2 As shown, in this embodiment, each adjustment component 60 is arranged circumferentially along the ring body 10. The first segment of the connecting rod 50 is connected to the adjustment component 60 at the end furthest from the second segment. The adjustment component 60 is configured as a round rod. The axial direction of the adjustment component 60 is arranged circumferentially along the drive ring 40, while the length direction of the connecting rod 50 is approximately radially along the drive ring 40. Thus, when the concentricity of each tile 20 is poor, the length of the adjustment component 60 can be adjusted so that the adjustment component 60 drives the end of the connecting rod 50 near the drive ring 40 to rotate around the drive ring 40. This allows the connecting rod 50 to drive the tile 20 to rotate, thereby adjusting the concentricity between each tile 20 and improving the concentricity between the tile 20 and the tire barrel, thus ensuring the clamping effect on the tire barrel.

[0035] like Figure 3As shown, in this embodiment, the adjusting component 60 includes a connector 61 and multiple adjusting components 62. The connector 61 has a first threaded hole and a second threaded hole at both ends, with the first and second threaded holes having opposite rotation directions. Adjusting components 62 are connected to both ends of the connector 61, and the adjusting components 62 are threadedly connected to the connector 61. Thus, the length of the adjusting component 60 can be adjusted by the length of the adjusting components 62 screwed into the first and second threaded holes. Specifically, in this embodiment, the connector 61 is a double-ended nut, and the adjusting components 62 are adjusting rods. The ends of the two adjusting rods near the connector 61 are respectively located in the first and second threaded holes, and the ends of the two adjusting rods away from the connector 61 each have connecting holes. The two connecting holes are respectively connected to the drive ring 40 and the connecting rod 50. Thus, when the connector 61 rotates, it can simultaneously push or pull the adjusting rods at both ends of the connector 61, thereby pushing or pulling the connecting rod 50 connected to the adjusting rods, thereby adjusting the position of the tiles 20 and increasing the spacing between the tiles 20. Concentricity is improved, thus significantly enhancing the clamping accuracy of the transfer ring and its versatility with tires of different diameters. This reduces additional costs and time losses due to equipment replacement. Furthermore, due to assembly and machining errors, the distance between the two connection points at both ends of the adjusting assembly 60 is not perfectly consistent. Therefore, the adjusting assembly 60 can be installed after assembling other components such as the connecting rod 50 and guide assembly 30. The adjustable length of the adjusting assembly 60 greatly reduces assembly difficulty and avoids the risk of rework due to assembly failure. It also helps to reduce the machining difficulty of the various components of the transfer ring. It should be noted that the length direction of the adjusting assembly 60 is its axial direction.

[0036] In this embodiment, the transmission ring further includes a driving member 70, which is drivingly connected to the driving ring 40 and drives the driving ring 40 to rotate. Figure 1 As shown, the drive component 70 can be fixed on the ring body 10 and disposed on one side of the drive ring 40 to avoid interference with other components. Optionally, the drive component 70 can be a cylinder, electric cylinder, etc.

[0037] The use of the transfer ring in this embodiment is as follows: the driving component 70 drives the driving ring 40 to rotate. The driving ring 40 is connected to each adjusting component 60. The adjusting component 60 drives the connecting rod 50 to rotate, thereby expanding and contracting the pad 20. The adjusting component 60 consists of adjusting rods at both ends and a double-ended nut in the middle. The length can be adjusted by rotating the double-ended nut to adjust the concentricity of each pad 20 and balance assembly errors. The second mounting base 22 and the rotating shaft are fixed on the pad 20. One end of the guide component 30 is fixed to the first mounting base 21, and the other end can slide along the second mounting base 22. When the pad 20 expands and contracts, the guide component 30 slides along the second mounting base 22. At this time, the first mounting base 21 can rotate around the rotating shaft according to the different expansion and contraction diameters to adjust the angle of the guide rod 31, so that the pad 20 and the tire can maintain good concentricity.

[0038] It should be noted that "multiple" in the above embodiments refers to at least two.

[0039] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0040] 1. This solves the problem of poor concentricity between the tiles of the transfer ring and the tire cylinder during the expansion and contraction process in the existing technology;

[0041] 2. By setting the guide component between two adjacent pads, and rotatably connecting one end of the guide component to one of the pads, the angle of the guide component relative to the pads can be adjusted. This allows the guide component to flexibly adjust its angle according to the expansion and contraction of the pads, thereby improving the concentricity between the pads and between the pads and the tire barrel. This avoids inconsistent expansion and contraction at both ends of the pads due to the action of the guide component. As a result, when the transfer ring clamps the tire barrel, each pad can make uniform contact with the outer periphery of the tire barrel, thereby reducing damage to the tire barrel and improving the reliability of the transfer ring clamping cylinder.

[0042] 3. Both ends of the guide component are movable connections, which helps to reduce the machining accuracy and installation difficulty of the guide component itself, thereby reducing machining costs and installation complexity.
