[0002] like Figure 1 As shown, the central mechanism of the vulcanizing machine includes a ring seat 01, a central rod 02, and a capsule clamp 03. The central rod 02 passes through the middle of the ring seat 01, and the capsule clamp 03 is coaxially fixed on the outer side of the ring seat 01. The capsule clamp 03 cooperates with the steel ring 05 to clamp the capsule 04.

[0003] During the use of the vulcanizing machine, it was found that the capsule clamp 03 and the ring seat 01 are prone to locking. It is time-consuming and laborious to remove the capsule clamp 03 from the ring seat 03, and sometimes even requires destructive disassembly. This causes great inconvenience to tire vulcanizing production, reduces production efficiency, and increases production costs. Utility Model Content

[0006] The first annular surface at the bottom inner side of the capsule clamp is detachably connected to the second annular surface at the bottom outer side of the ring seat;

[0007] The top end of the first annular surface in the capsule clamp is radially inwardly connected to the first annular receiving surface, and the top end of the second annular surface in the ring seat is radially inwardly connected to the second annular receiving surface.

[0008] An abutment protrusion is provided between the first annular bearing surface and the second annular bearing surface.

[0009] Preferably, the abutting protrusion is disposed on the first annular bearing surface;

[0010] The first annular bearing surface is provided with several abutting protrusions evenly arranged along the circumference of the ring seat.

[0011] Preferably, a first sealing ring groove is provided on the second annular receiving surface, and a first sealing element is provided in the first sealing ring groove;

[0012] When the abutting protrusion contacts the second annular bearing surface, the first annular bearing surface compresses the first sealing element.

[0013] Preferably, the radial inner end of the first annular receiving surface is connected upward to the first annular mating surface, and the radial inner end of the second annular receiving surface is connected upward to the second annular mating surface.

[0014] The first annular mating surface and the second annular mating surface are sealed together.

[0015] Preferably, a second sealing ring groove is provided on the second annular mating surface, and a second sealing element is provided in the second sealing ring groove.

[0016] Preferably, the first annular bearing surface has a planar structure perpendicular to the central axis of the ring seat.

[0017] Preferably, the height of the abutting protrusion protruding from the first annular bearing surface is 0.02 to 0.2 mm.

[0018] Preferably, the abutting protrusion is detachably connected to the first annular bearing surface or is designed as an integral part;

[0019] When the abutting protrusion is detachably connected to the first annular bearing surface, the abutting protrusion is a screw or a cylindrical pin, and the first annular bearing surface is provided with mounting holes that cooperate with the screw or cylindrical pin.

[0020] When the abutting protrusion is designed as an integral part of the first annular bearing surface, a boss is provided on the first annular bearing surface as the abutting protrusion.

[0021] Preferably, the angle between the generatrix of the first annular bearing surface and the central axis of the ring seat is an acute angle, and the end of the first annular bearing surface near the ring seat serves as an abutment protrusion that mates with the second annular bearing surface.

[0022] This utility model also provides a vulcanizing machine.

[0023] A vulcanizing machine, including a central mechanism for the vulcanizing machine.

[0024] The beneficial effects of this utility model are:

[0025] (1) In this utility model, the first annular receiving surface of the capsule clamp and the second annular receiving surface of the ring seat are in contact through the abutting protrusion, so that there is a gap between the first annular receiving surface of the capsule clamp and the second annular receiving surface of the ring seat, so that the first annular receiving surface and the second annular receiving surface are still separated by a certain distance after thermal expansion in the working state or under the action of internal pressure of the capsule, avoiding the problem of being difficult to disassemble after locking due to contact and squeezing.

[0026] (2) In this utility model, when screws or cylindrical pins are used as abutting protrusions, the protrusion height of the abutting protrusions can be adjusted by replacing screws or cylindrical pins of different lengths, thereby enhancing the applicability of the central mechanism.

[0027] (3) The abutting protrusion in this utility model can ensure that the first annular bearing surface and the second annular bearing surface are still separated by a certain distance after thermal expansion or under the action of internal pressure of the capsule in the working state, so as to avoid the problem of being difficult to disassemble after locking due to contact and squeezing. It also ensures that the first sealing element between the capsule clamp and the ring seat is under a certain amount of compression, thus ensuring the sealing effect.

[0028] (4) In this utility model, a number of abutting protrusions are evenly arranged along the circumference of the ring seat on the first annular receiving surface. The abutting protrusions effectively prevent the capsule clamp from locking with the ring seat. However, during use, the pressure between the abutting protrusions and the ring seat is greater, and the ring seat is easily worn during disassembly and assembly, resulting in problems such as reduced installation accuracy. When it is found that a set of abutting protrusions evenly arranged along the circumference has a serious wear problem on the ring seat, a new set of abutting protrusions can be set along the circumference on the radial inner or outer side of the set of abutting protrusions to ensure installation accuracy.

Detailed Implementation

[0041] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0042] Example 1:

[0043] like Figure 2 , Figure 3 As shown, a vulcanizing machine center mechanism includes a ring seat 01, a center rod 02, and a capsule clamp 03, with the center rod 02 passing through the middle of the ring seat 01;

[0044] The first annular surface 1 at the bottom inner side of the capsule clamp 03 is detachably connected to the second annular surface 2 at the bottom outer side of the ring seat 01; specifically, the first annular surface 1 at the bottom inner side of the capsule clamp 03 and the second annular surface 2 at the bottom outer side of the ring seat 01 are threaded together.

[0045] The top end of the first annular surface 1 in the capsule clamp 03 is radially inwardly connected to the first annular receiving surface 3, and the top end of the second annular surface 2 in the ring seat 01 is radially inwardly connected to the second annular receiving surface 4.

[0046] An abutment protrusion 5 is provided between the first annular bearing surface 3 and the second annular bearing surface 4, wherein at least one of the first annular bearing surface 3 and the second annular bearing surface 4 has an abutment protrusion 5. The contact area between the abutment protrusion 5 and the corresponding annular bearing surface 3 is not greater than 30% of the area of ​​the annular bearing surface 3.

[0047] In existing technologies, such as Figure 1As shown, thermal expansion or internal pressure within the capsule can cause the end face of the capsule clamp 03 to form a contact compression surface 06 with the end face of the ring seat 01, making it easy for the capsule clamp 03 and the ring seat 01 to lock together. In this application, the first annular receiving surface 3 of the capsule clamp 03 and the second annular receiving surface 4 of the ring seat 01 are in contact through an abutment protrusion 5, thus creating a gap between the first annular receiving surface 3 of the capsule clamp 03 and the second annular receiving surface 4 of the ring seat 01. This ensures that the first annular receiving surface 3 and the second annular receiving surface 4 remain separated by a certain distance even after thermal expansion or under the action of internal pressure within the capsule during operation, avoiding the problem of difficulty in disassembly after locking due to contact compression.

[0048] Preferably, the abutting protrusion 5 is disposed on the first annular bearing surface 3, that is, the abutting protrusion 5 is disposed on the capsule clamp 03. In this way, only the capsule clamp 03 needs to be modified, while the already installed ring seat 01 does not need to be disassembled and modified, making the modification simpler and easier to implement.

[0049] The first annular bearing surface 3 is provided with a plurality of abutting protrusions 5 evenly arranged along the circumference of the ring seat 01, that is, the distance between the central axis of all abutting protrusions 5 and the central axis of the ring seat 01 is equal.

[0050] The abutment protrusion 5 effectively prevents the capsule clamp 03 from locking with the ring seat 01. However, during use, the pressure between the abutment protrusion 5 and the ring seat 01 is greater, and the ring seat 01 is also prone to wear during disassembly and assembly, leading to problems such as reduced installation accuracy. When it is found that a set of abutment protrusions 5 evenly arranged in the circumferential direction has a problem of severe wear on the ring seat 01, a new set of abutment protrusions 5 can be set in the radial inner or outer side of the set of abutment protrusions 5 in the circumferential direction to ensure installation accuracy.

[0051] Preferably, a first sealing ring groove 41 is provided on the second annular receiving surface 4, and a first sealing element 6 is provided in the first sealing ring groove 41. The first sealing element 6 is an O-ring.

[0052] When the abutting protrusion 5 contacts the second annular receiving surface 4, the first annular receiving surface 3 compresses the first sealing element 6.

[0053] The abutment protrusion 5 in this utility model not only ensures that the first annular receiving surface 3 and the second annular receiving surface 4 remain a certain distance apart after thermal expansion or under the pressure inside the capsule during operation, thus avoiding the problem of difficulty in disassembly after locking due to contact and compression, but also ensures that the first sealing element 6 between the capsule clamp 03 and the ring seat 01 is under a certain amount of compression, thus guaranteeing the sealing effect.

[0054] Preferably, the radial inner end of the first annular receiving surface 3 is connected upward to the first annular mating surface 7, and the radial inner end of the second annular receiving surface 4 is connected upward to the second annular mating surface 8.

[0055] The first annular mating surface 7 and the second annular mating surface 8 are sealed together.

[0056] Preferably, a second sealing ring groove 81 is provided on the second annular mating surface 8, and a second sealing element 9 is provided in the second sealing ring groove 81. The second sealing element 9 is an O-ring.

[0057] Preferably, the first annular bearing surface 3 has a planar structure perpendicular to the central axis of the ring seat 01.

[0058] Preferably, the height of the abutting protrusion 5 protruding from the first annular receiving surface 3 is 0.02-0.2 mm, more preferably 0.05-0.12 mm, so that the first annular receiving surface 3 and the second annular receiving surface 4 are still separated by a certain distance after thermal expansion in the working state or under the action of the internal pressure of the capsule, while the sealing element between the capsule clamp 03 and the ring seat 01 is under a certain amount of compression to ensure the sealing effect.

[0059] Preferably, the abutting protrusion 5 is detachably connected to the first annular bearing surface 3 or is designed as an integral part;

[0060] When the abutting protrusion 5 is detachably connected to the first annular bearing surface 3, the abutting protrusion 5 is a screw or a cylindrical pin, and the first annular bearing surface 3 is provided with mounting holes that cooperate with the screw or cylindrical pin.

[0061] like Figure 4 As shown, when the screw acts as the abutment protrusion 5, the capsule clamp 03 is provided with a mounting hole that mates with the screw. After the screw is installed, it protrudes a certain distance from the first annular bearing surface 3. Two to three screws can be placed along the circumferential direction. When the capsule clamp 03 is installed with the ring seat 01, the second annular bearing surface 4 of the ring seat 01 contacts the screw first.

[0062] like Figure 5 As shown, when the cylindrical pin acts as the abutting protrusion 5, the capsule clamp 03 is provided with an installation hole that matches the cylindrical pin. After the cylindrical pin is installed, it protrudes a certain distance from the first annular bearing surface 3. Two to three screws can be placed along the circumferential direction. When the capsule clamp 03 is installed with the ring seat 01, the second annular bearing surface 4 of the ring seat 01 contacts the cylindrical pin first.

[0063] When the abutting protrusion 5 is designed as an integral part of the first annular bearing surface 3, a boss is provided on the first annular bearing surface 3 as the abutting protrusion 5.

[0064] When the abutting protrusion 5 and the first annular bearing surface 3 are designed as a single unit, such as Figure 6As shown, a boss can be integrally designed on the first annular bearing surface 3 as an abutment protrusion 5. Two to three bosses can be integrally set along the circumferential direction. When the capsule clamp 03 and the ring seat 01 are installed, the second annular bearing surface 4 of the ring seat 01 contacts the boss first.

[0065] Preferably, the angle between the generatrix of the first annular receiving surface 3 and the central axis of the ring seat 01 is an acute angle, that is, the first annular receiving surface has a conical structure. The end of the first annular receiving surface 3 near the ring seat 01 serves as an abutment protrusion 5 that mates with the second annular receiving surface 4. The end of the first annular receiving surface 3 near the ring seat 01 refers to the end with the smaller diameter in the conical structure of the first annular receiving surface 3. Specifically, the angle between the generatrix of the first annular receiving surface 3 and the central axis of the ring seat 01 is 85°, that is, the angle between the generatrix of the frustum surface of the first annular receiving surface 3 and the horizontal plane is 5°.

[0066] like Figure 7 As shown, the first annular bearing surface 3 is machined into a conical structure, which greatly reduces the mating area between the capsule clamp 03 and the ring seat 01.

[0067] Specifically, the end of the first annular bearing surface 3 furthest from the ring seat 01 is connected to the top of the first annular surface 1 via a horizontal annular surface 10, wherein the radial width of the horizontal annular surface 10 is 0.5 mm. The end of the first annular bearing surface 3 furthest from the ring seat 01 refers to the end with the larger diameter in the conical structure of the first annular bearing surface 3.

[0068] Example 2:

[0069] like Figure 8 As shown, a vulcanizing machine includes the vulcanizing machine center mechanism of Example 1.

[0070] Although the specific embodiments of the present utility model have been described above in conjunction with the accompanying drawings, they are not intended to limit the present utility model. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solution of the present utility model are still within the protection scope of the present utility model.
