Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of tire vulcanization, and particularly relates to a capsule-free internal pressure mechanism. Background Art
[0002] In the process of tire manufacturing, vulcanization is one of the key links to ensure tire performance and quality. The currently widely used capsule vulcanizer uses a capsule to provide internal pressure for the tire to achieve vulcanization molding. However, since the capsule itself is a flexible body, the pressure it can provide is limited, resulting in insufficient re-uniform distribution of the rubber compound inside the tire in the molten state during the vulcanization process. This deficiency directly affects the uniformity and dynamic balance performance of the tire, and further affects the driving stability and safety of the vehicle.
[0003] In addition, during the operation of the capsule vulcanizer, high-pressure gases such as nitrogen are required to provide pressure for the capsule, which not only increases the operation cost of the equipment but also increases the energy consumption. At the same time, there is a risk of bursting of the capsule under high-pressure conditions, posing a threat to production safety. Therefore, the capsule vulcanizer has significant deficiencies in improving vulcanization efficiency and reducing production risks.

[0017] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0018] 1. A capsule-free internal pressure mechanism disclosed by the present utility model. Compared with the traditional capsule pressure mechanism, the present utility model eliminates the capsule assembly. Through the linkage of the lifting assembly with the inner ring flexible module group and the outer ring flexible module group, the pressure adjustment process is made more reliable and the maintenance cost is lower. The lifting assembly drives the inner ring flexible module group to move back and forth longitudinally.

Detailed implementation manners
[0030] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the present utility model will be described and explained below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments provided by the present utility model without creative efforts fall within the scope of protection of the present utility model.
[0031] The embodiment of the present utility model provides a capsule-free internal pressure mechanism. Refer to Figures 1 to 7As shown in the figure, the pressure mechanism at least includes a guiding bottom plate 2, a lifting assembly 1, an inner ring flexible module group and an outer ring flexible module group. The lifting assembly 1 is arranged at the center of the guiding bottom plate 2; the inner ring flexible module group is sleeved outside the lifting assembly 1, connected to the lifting assembly 1, and moves up and down with the lifting assembly 1; the outer ring flexible module group is sleeved outside the inner ring flexible module group; the contact part between the inner ring flexible module group and the outer ring flexible module group is an inclined surface, and the outer ring flexible module group moves radially along the guiding bottom plate 2 with the lifting and lowering of the inner ring flexible module group. By setting the cooperation of the lifting assembly 1, the guiding bottom plate 2, the inner ring flexible module group and the outer ring flexible module group, the longitudinal movement of the inner ring flexible module group can drive the outer ring flexible module group to move back and forth radially along the guiding bottom plate 2, so as to realize the linkage between the inner ring flexible module group and the outer ring flexible module group. When the lifting assembly 1 drives the inner ring flexible module group to move upward, due to the inclined setting of the outer side of the inner ring flexible module group and its cooperation with the inner side of the outer ring flexible module group, the inner ring flexible module group drives the outer ring flexible module group to contract radially inward along the guiding bottom plate 2, so that the outer side of the outer ring flexible module group is separated from the vulcanized tire, realizing the release of the internal pressure; when the lifting assembly 1 drives the inner ring flexible module group to move downward, the inner ring flexible module group drives the outer ring flexible module group to expand radially outward along the guiding bottom plate 2, so that the outer side of the outer ring flexible module group is closely attached to the vulcanized tire, realizing the application of the internal pressure. This structural design enables the pressure mechanism not to rely on the traditional capsule design during the adjustment and control process, enhances the stability and reliability of the system, and can provide a more flexible pressure adjustment function in a variety of application scenarios.
[0032] Furthermore, a plurality of first grooves 201 are arranged on the guiding bottom plate 2 in the radial direction, first guide rails 202 are arranged on the first grooves 201, and a plurality of first guide rail grooves 301 are arranged on the side of the outer ring flexible module group connected to the guiding bottom plate 2. The first guide rails 202 are matched with the first guide rail grooves 301. By arranging the first grooves 201 on the guiding bottom plate 2 and setting the first guide rails 202 in the grooves, the outer ring flexible module group can be precisely matched with the first guide rails 202, ensuring the accuracy and stability of the radial reciprocating movement of the outer ring flexible module group.
[0033] Furthermore, a plurality of second grooves 302 are provided along the longitudinal direction on the inner side of the outer flexible module group, and second guide rails 303 are provided on the second grooves 302; a plurality of second guide rail grooves 401 are provided on the outer side of the inner flexible module group, and the second guide rails 303 are matched with the second guide rail grooves 401. Through the cooperation of the second grooves 302 and the second guide rails 303 between the inner flexible module group and the outer flexible module group, the transmission accuracy and stability of the entire pressure mechanism are further improved, the synchronism of the inner and outer flexible module groups is ensured, the movement of the inner and outer flexible module groups is made smoother, friction and wear are reduced, and at the same time, the durability and stability of the overall mechanism are improved. By designing the second guide rails 303 and the second guide rail grooves 401, the relative movement between the inner flexible module group and the outer flexible module group is further optimized, and the movement is more stable and accurate. At the same time, this design can effectively reduce friction and wear and improve the durability of the device.
[0034] Furthermore, at least two inner flexible modules 4 are provided in the inner flexible module group, and outer flexible modules 3 corresponding to the inner flexible modules 4 are provided in the outer flexible module group. The combination of multiple inner and outer flexible modules can achieve more complex motion patterns and adjustment effects. The design of multiple modules allows the system to be adjusted within a larger range, and each module can move independently, thereby providing more flexible and precise internal pressure control. The multi-module design increases the adjustability and expandability of the system, allowing the device to be used in a wider range of application scenarios. Through modular design, the maintenance and replacement costs can also be reduced, and the system function can be restored by simply replacing a single damaged module.
[0035] In some embodiments, as Figure 1 and Figure 2 shown, 4 inner flexible modules 4 are evenly distributed along the circumferential direction of the central axis. Such a design not only improves the symmetry and force balance of the entire pressure mechanism, but also realizes a more accurate pressure adjustment effect through the reasonable distribution of the inner flexible modules 4, effectively reducing the mechanical stress concentration problem caused by asymmetric layout, and improving the overall stability and reliability of the entire pressure mechanism; at the same time, 4 outer flexible modules 3 corresponding to the inner flexible modules 4 are also provided, and the configuration of the outer flexible modules 3 corresponding to the inner flexible modules 4 one by one further enhances the coordination and operation simplicity of the entire mechanism. This one-to-one design ensures the synchronism and accuracy of each module during movement, effectively reducing the mutual interference problem between modules, and enabling the pressure mechanism to still operate efficiently in a complex working environment.
[0036] Further, the lifting assembly 1 includes a central shaft 101, a first oil cylinder 102, and a first flange 103. The piston rod of the first oil cylinder 102 is connected to the central shaft 101. The first flange 103 is sleeved on the central shaft 101, and the first flange 103 is connected to at least one inner flexible module 4 in the inner ring flexible module group. By setting the first oil cylinder 102 to be connected to the central shaft 101 and the first flange 103 to be connected to the inner flexible module 4, the first oil cylinder 102 drives the central shaft 101 to move. The central shaft 101 further drives the first flange 103 and the inner flexible module 4 connected thereto to move. The movement of the inner flexible module 4 causes the outer flexible module 3 cooperating therewith to move radially along the guide bottom plate 2, completing the opening or contraction of part of the outer flexible module 3. This design enables the lifting assembly 1 to precisely control the lifting of part of the inner flexible module 4 and the opening or contraction of the outer flexible module 3, achieving precise control of the internal pressure of the system. The movement of the first flange 103 can be directly and precisely transmitted to the inner flexible module 4, ensuring that the movement of the lifting assembly 1 can quickly and accurately affect the state of the inner flexible module 4. This structural design further simplifies the transmission path of the pressure mechanism, reduces the wear between moving parts, and extends the service life of the pressure mechanism.
[0037] In some embodiments, the first flange 103 is in a disc shape. The two ends of the first flange 103 are respectively connected to two opposite inner flexible modules 4 in the inner ring flexible module group. When the first oil cylinder 102 drives the central shaft 101 to move, the central shaft 101 further drives the first flange 103 and the two opposite inner flexible modules 4 connected thereto to move. These two inner flexible modules 4 thus drive the two outer flexible modules 3 cooperating therewith to move radially along the guide bottom plate 2. Through the symmetric connection of the first flange 103 with the two inner flexible modules 4, when the central shaft 101 drives the first flange 103 to move, the two opposite inner flexible modules 4 can be lifted and lowered synchronously, thereby ensuring the radial movement synchronism and accuracy of the outer flexible module 3 cooperating therewith. This design of double-module linkage not only improves the stability of the movement but also reduces the structural complexity and wear risk.
[0038] In some embodiments, the shape of the first flange 103 is not limited to a disc shape and can also be in various forms such as a rectangle or a butterfly shape, as long as it can be effectively connected to the inner flexible module 4.
[0039] Furthermore, the lifting assembly 1 further includes a sleeve 107, a connecting seat 104, a plurality of second hydraulic cylinders 105, and a second flange 106. The sleeve 107 is sleeved on the central shaft 101. The connecting seat 104 is sleeved on the sleeve 107 and connected to one end of the sleeve 107. The piston rods of the plurality of second hydraulic cylinders 105 are connected to the connecting seat 104. The second flange 106 is sleeved on the central shaft 101 and connected to the other end of the sleeve 107. The second flange 106 is connected to the remaining inner ring active modules 4 in the inner ring active module group. Through the combination of the plurality of second hydraulic cylinders 105 and the connecting seat 104, the lifting assembly 1 can provide stronger lifting force and more precise control. The cooperation between the sleeve 107 and the second flange 106 ensures the linkage of each module, and at the same time can perform multi-point drive and adjustment as needed. The second flange 106 is driven by the plurality of second hydraulic cylinders 105 to move up and down, so that the second flange 106 drives the remaining inner ring active modules 4 to move up and down, so that the inner ring active modules 4 drive the remaining outer ring active modules 3 that cooperate with them to move radially along the guide bottom plate 2, and finally further complete the opening or contraction of all the outer ring active modules 3, realizing the application and release of the internal pressure of the tire vulcanization.
[0040] Furthermore, the first guide rail 202 and the second guide rail 303 are T-shaped guide rails, and the first guide rail groove 301 and the second guide rail groove 401 are T-shaped guide rail grooves. The design of the T-shaped guide rail 202 and the T-shaped guide rail groove 301 enhances the good guiding and stability of the inner and outer ring active module groups during the movement process, and at the same time reduces the offset or jamming problems caused by the lateral force. This structure is simple but can effectively reduce the frictional resistance, reduce mechanical wear, and at the same time provide a more stable moving guide, ensuring that the inner and outer ring active module groups 4, 3 can still maintain precise positioning under various complex working conditions.
[0041] Furthermore, the first guide rail 202 is threadedly connected to the guide bottom plate 2, and the second guide rail 303 is threadedly connected to the outer ring active module 3. The threaded connection between the first guide rail 202 and the guide bottom plate 2, and the second guide rail 303 and the outer ring active module 3 increases the flexibility and convenience of assembly. The threaded connection not only facilitates the disassembly, installation and maintenance of components, but also can provide a stable and reliable fixing force at the connection, further improving the overall strength and stability of the pressure mechanism. The threaded connection not only simplifies the installation process of the guide rail, but also does not require the disassembly of the overall structure when the guide rail needs to be repaired or replaced, improving the maintenance efficiency. At the same time, the threaded connection method provides higher connection strength and anti-vibration ability, adapting to high dynamic load scenarios.
[0042] In some embodiments, other fastening methods such as riveting, bonding or snap connection can be used, and the appropriate connection method is selected according to the specific application scenario to optimize the installation convenience and structural strength.
[0043] Furthermore, a self-lubricating pad 5 is provided on the side of the first guide rail 202 away from the guide bottom plate 2, and a self-lubricating pad 5 is provided on the side of the second guide rail 303 close to the outer ring movable module 3. The setting of the self-lubricating pads 5 on the first guide rail 202 and the second guide rail 303 can effectively reduce the friction between the guide rail and the guide rail groove, improving the smoothness and durability of the movement. The application of the self-lubricating pads 5 enables the inner and outer ring movable module groups to still maintain good movement performance after long-term operation, reducing the energy loss and temperature rise caused by friction, and improving the working efficiency of the pressure mechanism. The setting of the self-lubricating pads 5 enables the first guide rail 202 and the second guide rail 303 to operate stably for a long time without frequent lubrication. The self-lubricating pads 5 improve the overall reliability and operation smoothness of the pressure mechanism, while reducing the lubrication maintenance work and lowering the operation cost.
[0044] In some embodiments, the setting position of the self-lubricating pad 5 is set according to different force-bearing surfaces. In the present utility model, since the inner ring movable module 4 drives the outer ring movable module 3 to open or contract, the force-bearing surface between the two is located on the side of the second guide rail 303 close to the outer ring movable module 3. Therefore, the self-lubricating pad 5 is provided on this side, as Figure 6 shown in the setting position of the self-lubricating pad 5, and the outer ring movable module 3 moves back and forth radially along the guide bottom plate 2. The force-bearing surface between the two is located on the side of the first guide rail 202 away from the guide bottom plate 2. Therefore, the self-lubricating pad 5 is provided on this side, as Figure 5 shown in the setting position of the self-lubricating pad 5.
[0045] Furthermore, the capsule-free internal pressure pressure mechanism further includes a guide sleeve 6. The guide sleeve 6 is sleeved on the sleeve 107, and a lubricating device 7 is provided on the guide sleeve 6. The setting of the guide sleeve 6 and the lubricating device 7 thereon provides good support and lubrication guarantee for the lifting assembly 1 during the up and down movement. The application of the lubricating device 7 reduces the frictional resistance of the lifting assembly 1 during movement, reduces wear, improves the service life and operation smoothness of the pressure mechanism, and also improves the operation flexibility and response speed.
[0046] The working process of the above-mentioned capsule-free internal pressure pressure mechanism is as follows:
[0047] As Figure 1 and Figure 2As shown, when the internal pressure needs to be released after the tire vulcanization is completed, the first oil cylinder 102 drives the central shaft 101 to move upward. The central shaft 101 drives the first flange 103 to move upward. The upward movement of the first flange 103 drives the two opposite inner ring movable modules 4 to move upward. Since the contact part between the inner ring movable module 4 and the outer ring movable module 3 is an inclined surface, when the two inner ring movable modules 4 move upward along the track of the second guide rail 303, the two inner ring movable modules 4 will drive the two outer ring movable modules 3 that cooperate with them to move inward in a contracting motion, so that the outer sides of the two outer ring movable modules 3 are separated from the vulcanized tire. Subsequently, the second oil cylinder 105 is activated to drive the connecting seat 104 and the sleeve 107 to move upward. The sleeve 107 drives the second flange 106 to move upward. The second flange 106 drives the remaining two inner ring movable modules 4 to move upward. The remaining two inner ring movable modules 4 drive the two outer ring movable modules 3 that cooperate with them to move inward in a contracting motion again, so that the outer sides of the remaining two outer ring movable modules 3 are separated from the vulcanized tire again. When the outer sides of all the outer ring movable modules 3 are completely separated from the vulcanized tire, the release of the internal pressure of the tire is completed. When the internal pressure needs to be applied again for tire vulcanization, according to the above reverse operation, all the inner and outer ring movable modules are reset to complete the application of the internal pressure of the tire to maintain the internal pressure required for tire vulcanization.
[0048] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.
[0049] The above-described embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the utility model patent should be subject to the appended claims.
