Description

Technical Field

[0001] This invention relates to the field of tire processing technology, specifically to a tire inflation, cooling, and shaping device after vulcanization. Background Technology

[0002] In the tire manufacturing industry, post-vulcanization inflation, cooling, and shaping are crucial processes determining the quality of the finished tire. Currently, most post-vulcanization inflation, cooling, and shaping equipment on the market uses upper and lower clamps to achieve the post-inflation and shaping operation. For the cooling and shaping of large-size engineering tires, this lateral positioning method has significant drawbacks. Due to gravity, large-size tires are prone to sagging deformation when placed laterally, resulting in significant differences in deformation on both sides of the tire body. This not only affects the radial dimensional accuracy of the tire but also leads to uneven stress distribution within the tire, impacting the inflation and shaping effect.

[0003] Therefore, it is necessary to propose a tire vulcanization, inflation, cooling, and shaping device to solve the above problems. Summary of the Invention

[0004] (a) Technical problems to be solved The purpose of this invention is to provide a tire vulcanization, inflation, cooling and shaping device to solve the problems mentioned in the background art.

[0005] (II) Technical Solution To achieve the above objectives, the present invention provides the following technical solution: a tire vulcanization, inflation, cooling, and shaping device, comprising: A support frame, on which a movable frame is slidably connected horizontally; A micro-motion chuck, which is slidably connected to the bracket and driven by a telescopic rod to reciprocate along its axial direction; The movable clamp is fixedly connected to the movable frame. The movable clamp is provided with an inflation port. The movable clamp is driven by the movable frame to reciprocate along its axis. The movable clamp cooperates with the micro-motion clamp for clamping and sealing the tire. A lifting frame is located below a micro-motion chuck and is driven to move up and down by a linear drive mechanism. A lifting platform is slidably connected to the lifting frame along the axial direction of the micro-motion chuck.

[0006] Preferably, the top end of the movable frame is slidably connected to the support via rollers, and the bottom end of the movable frame is slidably connected to the support via a slide rail.

[0012] Preferably, side panels are fixedly connected to both sides of the lifting platform, and the distance between the two side panels is greater than the width of the tire.

[0013] (III) Beneficial Effects Compared with the prior art, the present invention provides a tire inflation cooling and shaping device after vulcanization, which has the following beneficial effects: 1.

It also clamps and seals the tire through the cooperation of a micro-movement chuck and a movable chuck, thereby achieving rapid clamping and sealing of the tire, making loading and unloading more convenient and improving production efficiency.

[0014] 2. The tire vulcanization inflation cooling and shaping device uses a third lead screw, a micro-motion chuck, and a movable chuck arranged coaxially to balance the forces on both sides of the tire, thus avoiding the problem of sealing failure and affecting the shaping effect caused by the tilting of the micro-motion chuck and the movable chuck.

[0015] 3. This tire vulcanization inflation cooling and shaping device vertically positions the tire, ensuring balanced force on both sides and consistent deformation.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0019] Please see Figure 1-4 As shown, a tire vulcanization, inflation, cooling, and shaping device includes a support 1, a micro-motion clamping plate 3, a movable clamping plate 4, and a lifting frame 5. The movable frame 2 is horizontally slidably connected to the support 1 and is driven to slide by a drive mechanism. The micro-motion clamping plate 3 is slidably connected to the support 1 and is driven to reciprocate along its axial direction by a telescopic rod 19. The movable clamping plate 4 is fixedly connected to the movable frame 2 and is provided with an inflation port 22. The movable clamping plate 4 is driven to reciprocate along its axial direction by the movable frame 2. The movable clamping plate 4 and the micro-motion clamping plate 3 cooperate to clamp and seal the tire. The lifting frame 5 is located below the micro-motion clamping plate 3 and is driven to rise and fall by a linear drive mechanism. A lifting platform 11 is slidably connected to the lifting frame 5 along the axial direction of the micro-motion clamping plate 3. Specifically, the telescopic rod 19 uses a pneumatic or hydraulic cylinder. Both the micro-motion chuck 3 and the movable chuck 4 are adapted to the tire to be inflated, cooled, and shaped. The micro-motion chuck 3 and the movable chuck 4 can be replaced according to the specifications of the inflated, cooled, and shaped tire to adapt it to the processing of tires of different specifications. The range of motion of the micro-motion chuck 3 is greater than its axial length to avoid interfering with the raising and lowering of the tire.

[0020] When tire inflation, cooling, and shaping are required, the tire is placed on the lifting platform 11. The lifting frame 5 is raised via a linear drive mechanism, aligning the tire's axle with the axis of the micro-motion clamp 3. Then, the movable clamp 4 is driven to slide towards the micro-motion clamp 3 via the movable frame 2, and the micro-motion clamp 3 is driven to slide towards the movable clamp 4 via the telescopic rod 19. The tire is clamped and sealed by the cooperation of the micro-motion clamp 3 and the movable clamp 4. The tire, micro-motion clamp 3, and movable clamp 4 combine to form a sealed cavity. Inflation is then performed into the cavity through the inflation port 22, allowing the tire to cool and shape. When the tire is raised or lowered via the lifting frame 5, the lifting platform 11 can drive the tire to slide along its axial direction to adjust its axial position.

[0021] To improve the stability of the horizontal sliding of the movable frame 2, the top of the movable frame 2 is slidably connected to the support 1 via rollers, and the bottom of the movable frame 2 is slidably connected to the support 1 via a slide rail.

[0022] In some embodiments, a third lead screw 16, driven by a third servo motor 17, is rotatably connected to the movable frame 2. A third threaded sleeve 18 is threaded onto the outer side of the third lead screw 16, and the third threaded sleeve 18 is fixedly connected to the bracket 1. Synchronous pulleys are fixedly connected to the output shaft of the third servo motor 17 and the outer side of the third lead screw 16, and the two synchronous pulleys are connected by a synchronous belt 15. When it is necessary to drive the movable chuck 4 to move, the third servo motor 17 is started, driving the third lead screw 16 to rotate via the synchronous belt 15. Under the interaction of the third lead screw 16 and the third threaded sleeve 18, the movable frame 2 slides relative to the bracket 1. By using the third servo motor 17 as the power source and the synchronous belt 15, synchronous pulleys, third lead screw 16, and third threaded sleeve 18 as the transmission mechanism, the movement distance of the movable chuck 4 can be controlled.

[0023] Specifically, the axes of the micro-motion chuck 3, the movable chuck 4, and the third lead screw 16 are collinear. By setting the axis of the third lead screw 16 to be collinear with that of the movable chuck 4, the movable chuck 4 is balanced under force when driven by the third lead screw 16, thus preventing the movable chuck 4 from tilting and affecting the clamping and sealing effect.

[0024] Specifically, a limiting post 20 is fixedly connected to the center of the side of the micro-motion clamping plate 3 away from the movable clamping plate 4, and a limiting cylinder 21 is slidably connected to the outer side of the limiting post 20. The limiting cylinder 21 is fixedly connected to the bracket 1. Preferably, there are multiple telescopic rods 19, which are distributed in an array around the circumference of the micro-motion clamping plate 3. Through the above settings, the sliding stability of the micro-motion clamping plate 3 is improved, and the tilting of the micro-motion clamping plate 3 is prevented from affecting the clamping and sealing effect.

[0025] In some embodiments, the linear drive mechanism includes a lifting frame 7, a lifting frame 5 fixedly connected to the lifting frame 7, and a lifting frame 7 slidably connected to a support 1 via a first slide rail 8. A first lead screw 6 is fixedly connected to the top of the lifting frame 7, and a threaded sleeve is threaded to the outer side of the first lead screw 6. The threaded sleeve is rotatably connected to the support 1 and driven to rotate by a first servo motor 23. Sliding the lifting frame 7 to the support 1 via the first slide rail 8 makes the lifting frame 5 more stable when lifting. When it is necessary to drive the lifting frame 5 to lift, the first servo motor 23 drives the threaded sleeve to rotate, and the threaded sleeve interacts with the first lead screw 6 to drive the lifting frame 7 to slide along the first slide rail 8, thereby driving the lifting frame 5 to lift.

[0026] In some embodiments, the lifting platform 11 is slidably connected to the lifting frame 5 via a second slide rail 9. A second threaded sleeve 12 is fixedly connected to the bottom end of the lifting platform 11. A second lead screw 10, driven to rotate by a second servo motor 14, is rotatably connected to the inner side of the lifting frame 5. The second lead screw 10 is threadedly connected to the second threaded sleeve 12. When it is necessary to adjust the axial position of the tire, the second lead screw 10 is driven to rotate by the second servo motor 14. Under the interaction of the second lead screw 10 and the second threaded sleeve 12, the lifting platform 11 is driven to slide along the second slide rail 9.

[0027] Specifically, side panels 13 are fixedly connected to both sides of the lifting platform 11, and the distance between the two side panels 13 is greater than the width of the tire. The side panels 13 are used to limit the axial position of the tire.

[0028] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
