Description

Technical Field

[0001] The utility model relates to the field of tire processing, and more particularly, to a transfer ring assembly for a forming machine and a forming machine. Background Art

[0002] The transfer ring of a passenger car radial tire forming machine is a device for carrying out the transfer of a tire crown or a green tire. The device forms a ring through multiple groups of jaws and clamps the tire crown or the green tire through multi-point positioning. The jaws are driven to move through their respective or overall power devices to realize the extension and retraction of the jaws. The transfer ring device can be designed as a moving part or a fixed part.

[0003] In order to integrate multiple functions, some pressure rollers are integrated on the transfer ring body of the existing transfer ring jaws. This design requires a notch for the pressure roller to penetrate on the ring body, so as to complete the established work. Due to the setting of the notch, clamping jaws cannot be installed at the notch, resulting in uneven circumferential distribution of the clamping jaws and inability to achieve true circle clamping, which causes serious deformation of the tire crown assembly at this place and affects the processing quality. At the same time, this design is mainly applied to fixed transfer ring devices. Since the split and combined pressure rollers are installed on the transfer ring body, the overall center of gravity of the transfer ring is relatively high, and it can only be applied to fixed transfer ring devices and cannot be applied to movable transfer ring devices, which also causes the center of gravity of the transfer ring device to shift and reduces the equipment stability, posing high design requirements for the overall design of the equipment. Summary of the Utility Model

[0004] The main object of the present utility model is to provide a transfer ring assembly for a forming machine and a forming machine, so as to solve the problem of uneven distribution of clamping jaws of the transfer ring assembly in the prior art.

[0005] To achieve the above object, according to one aspect of the present utility model, there is provided a transfer ring assembly for a forming machine, including a transfer ring body and a plurality of clamping jaws. The transfer ring body has a notch for a pressure roller to penetrate; the clamping jaws are connected to the transfer ring body and are radially movably arranged relative to the transfer ring body to clamp a tire tube. All the clamping jaws include avoidance clamping jaws located on the side of the notch. The avoidance clamping jaws also have a movement along a first direction relative to the transfer ring body. The first direction forms an angle with the radial direction of the transfer ring body. The avoidance clamping jaws have a clamping position and an avoidance position for movement along the first direction. When the avoidance clamping jaws are located at the clamping position, the avoidance clamping jaws are evenly distributed along the circumferential direction of the transfer ring body with other clamping jaws; when the avoidance clamping jaws are located at the avoidance position, the avoidance clamping jaws move away from the notch and avoid the movement of the pressure roller.

[0006] Further, there are multiple avoidance clamping claws, and avoidance clamping claws are arranged on both sides in the circumferential direction of the notch. When the avoidance clamping claws are switched from the avoidance position to the clamping position, the avoidance clamping claws on both sides move towards each other.

[0007] Further, when the avoidance clamping claws are in the clamping position, the first direction is the tangential direction of the position where the avoidance clamping claws are located.

[0008] Further, the transfer ring assembly further includes a guide rail assembly. The guide rail assembly is arranged between the transfer ring body and the avoidance clamping claws, and the guide rail assembly extends along the first direction. When the avoidance clamping claws are in the clamping position, they can be located inside the notch.

[0009] Further, the transfer ring assembly further includes an avoidance driving member. The avoidance driving member is drivingly connected to the avoidance clamping claws and drives the avoidance clamping claws to move along the first direction.

[0010] Further, the end of at least one clamping claw other than the avoidance clamping claws has a roller structure for performing rolling.

[0011] According to another aspect of the present invention, there is provided a forming machine, including a base, the above-mentioned transfer ring assembly, and a pressure roller assembly. The transfer ring assembly is connected to the base, and the pressure roller assembly can extend into the transfer ring body of the transfer ring assembly through the notch.

[0012] Further, the transfer ring assembly is movably arranged on the base.

[0013] Further, the pressure roller assembly is separately arranged from the transfer ring assembly.

[0014] Further, the pressure roller assembly includes a pressure roller. The pressure roller is movably arranged relative to the base and has a rolling state of moving to the notch and an external processing state of moving to an external working station.

[0015] By applying the technical solution of the present invention, by providing avoidance clamping claws that can approach and move away from the notch for the pressure roller to extend into the transfer ring body, on the one hand, when the avoidance clamping claws approach the notch and are in the clamping position, the avoidance clamping claws can cooperate with other clamping claws so that all the clamping claws can be evenly distributed in the circumferential direction of the transfer ring body, thus meeting the true circle requirement during the clamping of the transfer ring assembly, thereby avoiding deformation of the tire carcass due to uneven force and ensuring the processing quality. On the other hand, when the avoidance clamping claws move away from the notch and are in the avoidance position, the pressure roller can extend into the transfer ring body through the notch to complete the rolling action. In this way, the transfer ring assembly can not only complete the clamping action of the tire carcass with high quality but also complete the rolling action in cooperation with the pressure roller.

[0021] It should be noted that, without conflict, the embodiments in this application and the features in the embodiments can be combined with each other. The following will refer to the drawings and combine with the embodiments to detail the present utility model.

[0022] It should be pointed out that unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by those of ordinary skill in the technical field to which this application belongs.

[0023] In the present utility model, unless otherwise stated, the orientation terms such as "upper, lower, top, bottom" are usually in the direction shown in the drawings, or in the vertical, perpendicular or gravitational direction of the component itself; similarly, for the convenience of understanding and description, "inner, outer" refer to the inner and outer of the contour of each component itself, but the above orientation terms do not limit the present utility model.

[0024] In order to solve the problem that the clamping claws of the transfer ring assembly in the prior art are unevenly distributed, the present utility model provides a transfer ring assembly for a molding machine and a molding machine.

[0025] Such as Figure 1 、 Figure 2A transfer ring assembly for a molding machine as shown includes a transfer ring body 10 and a plurality of clamping claws 20. The transfer ring body 10 has a notch 11 for a pressure roller 41 to extend into; the clamping claws 20 are connected to the transfer ring body 10 and are radially movably arranged relative to the transfer ring body 10 to clamp the tire carcass. All the clamping claws 20 include a retracting clamping claw 21 located on the side of the notch 11. The retracting clamping claw 21 also has a movement along a first direction relative to the transfer ring body 10. An angle is formed between the first direction and the radial direction of the transfer ring body 10. The retracting clamping claw 21 has a clamping position and a retracting position for movement along the first direction. When the retracting clamping claw 21 is in the clamping position, the retracting clamping claw 21 and the other clamping claws 20 are evenly distributed along the circumferential direction of the transfer ring body 10; when the retracting clamping claw 21 is in the retracting position, the retracting clamping claw 21 moves away from the notch 11 to avoid the movement of the pressure roller 41.

[0026] In this embodiment, by providing the retracting clamping claw 21 that can approach and move away from the notch 11 of the transfer ring body 10 where the pressure roller 41 extends into, on the one hand, when the retracting clamping claw 21 approaches the notch 11 and is in the clamping position, the retracting clamping claw 21 can cooperate with the other clamping claws, so that all the clamping claws 20 can be evenly distributed along the circumferential direction of the transfer ring body 10, thus meeting the true circle requirement when the transfer ring assembly clamps, avoiding deformation of the tire carcass caused by uneven force, and ensuring the processing quality. On the other hand, when the retracting clamping claw 21 moves away from the notch 11 and is in the retracting position, the pressure roller 41 can extend into the transfer ring body 10 through the notch 11 to complete the rolling action. In this way, the transfer ring assembly can not only complete the clamping action of the tire carcass with high quality, but also complete the rolling action in cooperation with the pressure roller 41.

[0027] It should be noted that the transfer ring body 10 of this embodiment provides rigid support for the entire transfer ring assembly and can be arranged in the main line of the molding machine.

[0028] In this embodiment, in order to leave enough space for the pressure roller 41 to extend into the transfer ring body 10, the transfer ring body 10 is provided with a relatively large notch 11. A plurality of retracting clamping claws 21 are provided, and the retracting clamping claws 21 are provided on both circumferential sides of the notch 11. When the retracting clamping claws 21 on both sides switch from the retracting position to the clamping position, they move towards each other. In this way, the plurality of retracting clamping claws 21 can make up for the missing clamping claws 20 at the notch 11 through movement, so that the clamping claws 20 are evenly distributed along the circumferential direction of the transfer ring body 10, thus forming a complete ring to meet the clamping requirements of the transfer ring assembly and avoid deformation of the tire carcass. Moreover, the retracting clamping claws 21 are arranged in the circumferential direction of the notch 11 and move approximately along the circumferential direction of the transfer ring body 10, so that the movement and avoidance of the retracting clamping claws 21 can be completed within the internal space of the transfer ring body 10, without increasing the space occupied in the axial direction of the transfer ring body 10, which is beneficial to saving the space requirement of the transfer ring assembly and ensuring the overall center of gravity of the transfer ring assembly to prevent the situation of center of gravity deviation.

[0029] The avoidance clamping claws 21 of this embodiment are provided in two, one is provided on each of the circumferential two sides of the notch 11, so as to meet the uniform distribution requirement of the clamping claws 20 on the transfer ring body 10 when the avoidance clamping claws 21 are in the clamping position. Of course, according to actual needs, the avoidance clamping claws 21 can also be provided in one or more. For example, when the space required by the pressing roller 41 is small and the notch 11 is set to be small, only one avoidance clamping claw 21 can be provided on one side of the notch 11. When the transfer ring assembly needs to be clamped, only the position of one avoidance clamping claw 21 needs to be moved and moved to the circumferential position evenly distributed with other clamping claws 20 on the transfer ring body 10. When the space of the pressing roller 41 is larger and the notch 11 is set to be larger, multiple avoidance clamping claws 21 can be provided on each of the two sides of the notch 11. When the transfer ring assembly needs to clamp the tire carcass, multiple avoidance clamping claws 21 move to the clamping position at the same time and are evenly distributed with other clamping claws 20 in the circumferential direction of the transfer ring body 10. It should be noted that the circumferential direction of the notch 11 refers to the circumferential direction of the transfer ring body 10, that is, the arrangement direction of the clamping claws 20.

[0030] In this embodiment, when the avoidance clamping claw 21 is in the clamping position, the first direction is the tangential direction of the position where the avoidance clamping claw 21 is located, which is a straight line direction. Thus, on the one hand, the avoidance clamping claw 21 can move away from the notch 11 perpendicular to the extending and retracting direction of the pressing roller 41, so as to avoid the circumferential position where the pressing roller 41 extends into the notch 11 and prevent interference with the pressing roller 41. On the other hand, when the avoidance clamping claw 21 moves to the clamping position perpendicular to the extending and retracting direction of the pressing roller 41, it is arranged in a circumferential array with other clamping claws 20 along the transfer ring body 10, thereby improving the roundness of the clamping claws 20 and reducing the deformation of the tire carcass. Of course, the first direction can also be set as the circumferential direction of the transfer ring body 10, set as an arc direction. In this way, the avoidance clamping claw 21 and other clamping claws 20 are always distributed on the same circumference. When the avoidance clamping claw 21 moves to the avoidance position, it avoids the notch 11 position for the pressing roller 41 to enter and exit. When the pressing roller 41 is away from the notch 11, the avoidance clamping claw 21 can rotate along the circumferential direction of the transfer ring body 10 to be evenly distributed with other clamping claws 20 to form a complete circle and complete the clamping action.

[0031] In this embodiment, the transfer ring assembly further includes a guide rail assembly. The guide rail assembly is disposed between the transfer ring body 10 and the avoidance clamping jaw 21, and the guide rail assembly extends along the first direction. When the avoidance clamping jaw 21 is in the clamping position, it can be located inside the notch 11. In this way, on the one hand, the guide rail assembly can play a guiding role for the movement of the avoidance clamping jaw 21. On the other hand, when the avoidance clamping jaw 21 moves to the edge of the notch 11 and continues to move inside the notch 11, the guide rail assembly plays a supporting role for the avoidance clamping jaw 21 to support the avoidance clamping jaw 21 to smoothly move inside the notch 11, so as to be evenly distributed with other clamping jaws 20 in the circumferential direction of the transfer ring body 10. Specifically, the guide rail assembly can be set in the form of mutual cooperation between a guide rail and a slider. The guide rail can be disposed in the circumferential direction of the transfer ring body 10 and can extend along the first direction to the notch 11. The slider is disposed on the side of the avoidance clamping jaw 21 close to the transfer ring body 10 for cooperation with the guide rail. Of course, the guide rail can also be disposed on the side of the avoidance clamping jaw 21 close to the transfer ring body 10, and the slider is disposed on the transfer ring body 10 for cooperation with the guide rail, as long as it can provide support and guidance for the movement of the avoidance clamping jaw 21.

[0032] In this embodiment, the transfer ring assembly further includes an avoidance driving member 30. The avoidance driving member 30 is drivingly connected to the avoidance clamping jaw 21 and drives the avoidance clamping jaw 21 to move along the first direction. In this way, the avoidance clamping jaw 21 can be switched between the avoidance position and the clamping position under the drive of the avoidance driving member 30, so as to complete the avoidance of the pressing roller 41 and the clamping of the tire carcass. The avoidance driving member 30 of this embodiment is disposed on the side of the avoidance clamping jaw 21 away from the notch 11 to avoid interfering with the movement of the avoidance clamping jaw 21 and the pressing roller 41. Optionally, the avoidance driving member 30 can use a cylinder, an electric cylinder, a motor, etc.

[0033] In this embodiment, in order to integrate multiple functions of the transfer ring assembly, at least one clamping jaw 20 other than the avoidance clamping jaw 21 has a roller structure 22 for performing rolling. When the transfer ring assembly clamps the tire carcass, the clamping jaw 20 where the roller structure 22 is located is evenly distributed with other clamping jaws 20 including the avoidance clamping jaw 21 in the circumferential direction of the transfer ring body 10. In this way, the roller structure 22 can not only complete the rolling action when rolling is required, but also abut against the tire carcass when the transfer ring assembly clamps the tire carcass to support the tire carcass to prevent deformation of the tire carcass.

[0034] The specific usage process of this embodiment is as follows: When the transfer ring assembly moves to the clamping station of the tire carcass, the avoidance driving member 30 drives the avoidance clamping claw 21 to the clamping position. All the clamping claws 20 respectively drive their own clamping jaws and roller structures 22 to extend and then lock, clamping and fixing the tire carcass. When the transfer ring assembly moves to the combination station, all the clamping claws 20 respectively drive their own clamping jaws and roller structures 22 to retract, releasing the tire carcass. Then, the avoidance driving member 30 drives the avoidance clamping claw 21 to the avoidance position, providing space for the entry of the pressing roller 41. Then, the pressing roller 41 can enter the transfer ring body 10 from the notch 11 for the rolling operation, and withdraw from the notch 11 of the transfer ring body 10 after completion. Then, the avoidance driving member 30 drives the moving clamping claw 20 to the clamping position. All the clamping claws 20 respectively drive their own clamping jaws and roller structures 22 to extend and then lock, clamping and fixing the tire carcass to complete the tire unloading operation. After completing the tire unloading operation, the ring body moves to the tire carcass clamping position. Repeat the above actions for the production cycle.

[0035] This embodiment also provides a molding machine, including a base, the above-mentioned transfer ring assembly, and a pressing roller assembly 40. The transfer ring assembly is connected to the base, and the pressing roller assembly 40 can extend into the interior of the transfer ring body 10 of the transfer ring assembly through the notch 11. In this way, different from the traditional setting method of integrating the pressing roller assembly 40 and the transfer ring assembly, the setting method of this embodiment avoids the center of gravity offset and elevation of the transfer ring assembly caused by the pressing roller assembly 40, thereby improving the stability of the transfer ring assembly. Moreover, the transfer ring assembly is small in volume, greatly saving the space requirement of the transfer ring assembly and avoiding occupying more space of the molding machine.

[0036] In this embodiment, the transfer ring assembly is movably arranged on the base, and the pressing roller assembly 40 is separately arranged from the transfer ring assembly, that is, the transfer ring assembly can move along the axial direction of the transfer ring body 10, while the pressing roller assembly 40 does not move together with the transfer ring assembly. In this way, when the pressing roller assembly 40 and the transfer ring assembly do not need to cooperate, the pressing roller assembly 40 can be applied to other stations, and the transfer ring assembly can also complete clamping independently. When the pressing roller assembly 40 and the transfer ring assembly need to cooperate, the transfer ring assembly moves axially along the transfer ring body 10 to align with the pressing roller assembly 40, and the avoidance clamping claw 21 avoids the notch 11 position. The pressing roller assembly 40 extends into the notch 11, and the pressing roller assembly 40 and the transfer ring assembly cooperate to complete the rolling. This setting method makes the transfer ring assembly as a whole light and small in volume, thereby improving the stability of the transfer ring assembly and saving space.

[0037] In this embodiment, the pressure roller assembly 40 includes a pressure roller 41. The pressure roller 41 is disposed at one end of the pressure roller assembly 40 close to the central axis of the transfer ring body 10 and is movably disposed relative to the base. In this way, the pressure roller 41 has a roller pressing state of moving to the notch 11 and an external processing state of moving to an external work station. When the transfer ring assembly moves axially along the transfer ring body 10 to align with the pressure roller assembly 40, the pressure roller 41 moves in a direction close to the transfer ring body 10 and moves to the notch 11 to complete the roller pressing. When the transfer ring assembly needs to be moved and clamped, the pressure roller 41 moves in a direction away from the transfer ring body 10 and exits the notch 11, thereby avoiding interference with the transfer ring assembly and enabling switching to the external processing state for other external processing.

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

[0040] 1. Solved the problem of uneven distribution of the clamping claws of the transfer ring assembly in the prior art;

[0041] 2. Meet the true round requirement when the transfer ring assembly is clamped, thereby avoiding deformation of the tire carcass due to uneven force;
