[0038] An embodiment of the present invention provides a tire bead shaping device. Specifically, Figure 1As shown, the tire bead shaping device comprises a mounting seat 1, a shaping mechanism 2 and a cooling mechanism 3. Specifically, the shaping mechanism 2 and the cooling mechanism 3 are both arranged on the mounting seat 1, the shaping mechanism 2 is used to support and fix the tire bead, and the cooling mechanism 3 is used to cool the tire bead on the shaping mechanism 2 to accelerate the shaping process of the tire bead.

[0039] refer to Figure 2 As shown, the shaping mechanism 2 includes a fixing frame 201, a fixing cylinder 2031, a support portion 21 and a first driving portion 210. The fixing frame 201 is arranged on the upper end surface of the mounting seat 1 and along the first direction ( Figures 1 to 3 The fixing cylinder 2031 is arranged on the upper part of the fixing frame 201, the first driving part 210 and the supporting part 21 are both located on the fixing cylinder 2031 and the supporting part 21 is connected to the output end of the first driving part 210, and the tire bead can be sleeved on the outer circumferential surface of the supporting part 21.

[0040] Exemplarily, the outer contour of the support portion 21 is circular, which can extend into the interior of the tire bead, and can shrink (i.e., gather toward the interior near the center of the circle) or expand (i.e., expand toward the exterior away from the center of the circle) relative to its center under the drive of the first drive portion 210, so that the outer contour of the support portion 21 can adapt to tire beads of different diameters, thereby achieving the shaping of tire beads of different models.

[0041] Specifically, the first driving part 210 can be a hydraulic transmission mechanism, a pneumatic transmission mechanism, or a transmission mechanism driven by a motor, as long as it can output linear motion, and the present application does not impose any limitation on this.

[0042] refer to Figure 3 As shown, the cooling mechanism 3 includes a fixing plate 301 and a fan assembly. The fixing plates 301 are extended along the first direction and arranged on the mounting seat 1, and the number of the fixing plates 301 is two, and the two fixing plates 301 are extended along the second direction ( Figures 1 to 3 (as shown in the Y direction) interval setting.

[0043] Along the third direction ( Figure 1 and Figure 2 As shown in the Z direction, the projection of the shaping mechanism 2 is located between the projections of the two fixing plates 301. A fan assembly is provided on each fixing plate 301, and the position of each fan assembly corresponds to the position of the support portion 21 in the shaping mechanism 2, so as to provide cooling airflow for the tire bead sleeved on the support portion 21, thereby accelerating the cooling and shaping of the tire bead.

[0044] Exemplarily, the fan assembly includes a cylinder 302, a fixing ring 303, a fan 304 and a grille 305. There are two cylinders 302, which are respectively mounted on opposite sides of the two fixing plates 301. The inner surfaces of the two cylinders 302 are respectively fixedly mounted with fixing rings 303, and each fixing ring 303 is mounted with a fan 304. Grilles 305 are fixedly mounted at both ends of the inner walls of the two cylinders 302. When the fan 304 rotates, the airflow flows through the grille 305 to the tire bead on the shaping mechanism 2, thereby cooling the tire bead.

[0045] Continue to refer Figure 2 The tire bead shaping device also includes a second driving part 4 (specifically, a motor) arranged on the mounting seat 1 and a bearing 202 embedded in the fixing frame 201, a fixing cylinder 2031 is arranged in the bearing 202 (the fixing cylinder 2031 can be installed on the inner ring of the bearing 202 by insertion, and the fixing cylinder 2031 is located on the side of the bearing 202 facing the cooling mechanism 3), and the supporting part 21 is connected to the middle part of the fixing cylinder 2031.

[0046] The support part 21 is disposed on the bearing 202 through the fixing tube 2031 and the support part 21 and the fixing tube 2031 can rotate together relative to the fixing frame 201, so that the cooling fan 304 can cool all positions of the tire bead and improve the shaping speed of the tire bead.

[0047] In one embodiment of the present application, the number of the fixing frames 201 can be set to two, and the two fixing frames 201 are arranged on the mounting seat 1 at intervals along the third direction, wherein one fixing frame 201 is arranged close to the cooling mechanism 3, and the other fixing frame 201 is located on the side of the fixing frame 201 away from the cooling mechanism 3. A bearing 202 is embedded on each fixing frame 201, and the setting position of the bearing 202 is adapted to the setting position of the support portion 21. The two ends of the fixing cylinder 2031 are respectively inserted into the inner rings of the two bearings, and one end of the fixing cylinder 2031 extends out of the fixing frame 201 close to the cooling mechanism 3, so that the support portion 21 installed on the fixing cylinder 2031 can be located between the two fan assemblies of the cooling mechanism 3, so as to accelerate the cooling of the tire.

[0048] A driven gear 401 is also sleeved on the outer periphery of the fixed cylinder 2031, and a driving gear 402 is sleeved on the output end of the second driving part 4. The driving gear 402 and the driven gear 401 are meshed and connected to form a gear set. The output end of the second driving part 4 is transmission-connected to the fixed cylinder 2031 through the gear set, so that the second driving part 4 can drive the fixed cylinder 2031 and the support part 21 installed on the fixed cylinder 2031 and the tire bead on the support part 21 to rotate together.

[0049] Further references Figure 1 and Figure 2A connection block 2032 is also provided on one end of the fixed cylinder 2031 extending outside the fixed frame 201, and the first driving part 210 is installed on the connection block 2032. That is, the first driving part 210 is installed on the fixed cylinder 2031 through the connection block 2032.

[0050] For example, Figure 4 As shown, the support part 21 includes a first slider group, a second slider group and a support block group. The first slider group includes a plurality of first sliders 204 arranged at intervals along the circumference, the second slider group includes a plurality of second sliders 205 arranged at intervals along the circumference, and the support block group includes a plurality of support blocks 211 arranged at intervals along the circumference. Each first slider 204 and each second slider 205 are arranged at intervals along the circumferential direction, and adjacent first sliders 204 and second sliders 205 are hinged by metal rods 208. A support block 211 is respectively arranged on each of the plurality of first sliders 204 and / or the plurality of second sliders 205, and the support block 211 is used to support in the tire bead, and at least one first slider 204 or second slider 205 is connected to the output end of the first driving part 210.

[0051] like Figure 2 As shown, a plurality of first slide grooves 2033 and a plurality of second slide grooves 2034 are provided on the end surface of the fixed cylinder 2031, and each of the first slide grooves 2033 and each of the second slide grooves 2034 extend along the radial direction of the fixed cylinder 2031, and each of the first slide grooves 2033 and each of the second slide grooves 2034 are alternately arranged one by one. Among them, each of the first sliders 204 is slidably arranged in each of the first slide grooves 2033, and the first slide grooves 2033 can guide the first sliders 204 arranged therein; each of the second sliders 205 is slidably arranged in each of the second slide grooves 2034, and the second slide grooves 2034 can guide the second sliders 205 arranged therein.

[0052] By such arrangement, when the first driving unit 210 is started, one of the support blocks 211 will be pushed to move. Since each support block 211 is connected to the first slider 204 or the second slider 205, when one of the support blocks 211 moves inward or outward, the whole group of support blocks 211 will be driven to move toward or away from the center of the circle, thereby changing the distance between the support blocks 211. That is, such an arrangement can change the distance between the support blocks 211 according to the tire model, thereby realizing the shaping of tires with different diameters.

[0053] Specifically, the first slider 204 and the second slider 205 are arranged on one side of the outer wall of the connecting block 2032 and are arranged apart from each other. A fixed frame 206 is fixedly installed on the top of each first slider 204, and each support block 211 is respectively installed on the top of each fixed frame 206. The output end of the first driving unit 210 is fixedly inserted on the outer wall of one of the fixed frames 206.

[0054] In order to clearly show the connection structure between two adjacent metal rods 208, Figure 4 A fixed frame 206 and a support block 211 disposed thereon are omitted. Exemplarily, the inner surface wall of each fixed frame 206 is fixedly inserted with a first rod 207, the top of each second slider 205 is fixedly inserted with a second rod 209, and both ends of each metal rod 208 are hinged to the corresponding first rod 207 and second rod 209.

[0055] Exemplarily, a support plate 213 is provided on the surface of each support block 211 facing the tire bead, and the shape of the support plate 213 is adapted to the shape of the tire bead to be shaped. Specifically, the support plate 213 includes multiple groups, and each group of support plates is adapted to a tire bead of a certain shape. Among them, the number of support plates 213 in each group of support plates is equal to the number of support blocks 211 and the positions correspond one to one, and each support block 211 is detachably connected to the support plate 213 corresponding thereto. For example, each support plate 213 can be adsorbed on the support block 211 corresponding thereto by a magnet 212. When it is necessary to shape the tire bead, a group of support plates that are adapted to the shape of the tire bead to be shaped is selected, and then each support plate 213 in the group of support plates is adsorbed on the support block 211 corresponding thereto by a magnet 212, so as to realize the connection between the support plate 213 and the support block 211.

[0056] It should be noted that, in one embodiment of the present application, the first drive unit 210 is a hydraulic cylinder and the second drive unit 4 is a motor, but in other embodiments of the present application, the first drive unit 210 and the second drive unit 4 may also be other drive devices. As long as the functions of the first drive unit 210 and the second drive unit 4 can be realized, the present application does not limit the types of the first drive unit 210 and the second drive unit 4.

[0057] The following is a brief introduction to the working principle of the tire bead shaping device provided by the present application:

[0058] First, fix the device at a specified position. Since the support plate 213 is adsorbed on the support block 211 by the magnet 212, the size of the support plate 213 can be changed according to the size of the tire. Then, the tire is placed on the outer wall of a group of support blocks 211, and the first driving unit 210 (such as a hydraulic rod) is started, which will push one of the support blocks 211 to move. Since each support block 211 is movably connected to the first slider 204 through a metal rod 208, when one of the support blocks 211 moves inward or outward, it will drive the entire group of support blocks 211 to move toward the center of the circle or outward from the center of the circle until it abuts against the inner wall of the tire bead, thereby achieving support of the tire bead by the support plate 213. In addition, the present application can also change the distance between the support blocks 211 according to the tire model, thereby achieving shaping of tires of different models. After the support plate 213 has achieved positioning for the tire bead, the fan 304 is started to blow cold air toward the tire, thereby accelerating the cooling speed of the tire, and at the same time, the second driving unit 4 (specifically, a motor) is started, and the fixed cylinder 2031 is driven to rotate under the meshing action between the driving gear 402 and the driven gear 401, thereby driving the tire to rotate, so that the tire can be evenly cooled and the cooling effect can be improved. In addition, the support plate 213 of the present application is magnetically attracted to the support block 211 by the magnet 212, so the size of the support plate can be changed according to the needs of tires of different sizes, and it can be quickly replaced by means of magnets, which is more applicable.

[0059] Although the present invention has been illustrated and described with reference to certain preferred embodiments of the present invention, it should be understood by those skilled in the art that the above contents are further detailed descriptions of the present invention in combination with specific embodiments, and it cannot be determined that the specific implementation of the present invention is limited to these descriptions.
