Description

Technical Field

[0001] The invention relates to a component structure of a tire shaping vulcanizer, in particular to a combined lower supporting plate of a steamer of a hydraulic vulcanizer. Background Art

[0002] Hydraulic vulcanizers, due to their more uniform force distribution, produce higher-quality vulcanized tires, and their market share is increasing. Of course, hydraulic vulcanizers also have their own shortcomings, among which the maintenance of the booster cylinder is the most troublesome issue for maintenance personnel. Although the upper-mounted booster cylinder has a larger disassembly space than the previous lower-mounted booster cylinder, due to the limitations of the traditional integral lower support plate structure, when the booster cylinder needs maintenance, the lower support plate must be lifted out as a whole. To remove the lower support plate, the central mechanism and the associated piping must be removed first, which invisibly greatly increases the maintenance workload of the booster cylinder and the labor intensity of the maintenance personnel. Summary of the Invention

[0003] In response to the shortcomings of the existing technology, the present invention provides a combined lower support plate for a hydraulic vulcanizer steamer, which overcomes the problem of difficulty in disassembling the booster cylinder under the traditional integral lower support plate structure, so that the maintenance work of the booster cylinder and the central mechanism can be carried out independently, thereby greatly reducing the maintenance workload and labor intensity.

[0004] The present invention achieves the above-mentioned purpose through the following technical solutions:

[0005] The combined lower support plate of the hydraulic vulcanizer steamer consists of an inner ring and an outer ring. The inner ring is sleeved on the center mechanism for installation of the center mechanism. The outer ring is supported by the boosting cylinder and sleeved outside the inner ring to withstand the clamping force of the boosting cylinder. The inner ring and the outer ring are connected by screws through a connecting flange. A groove is opened on the inner side of the outer ring for installing the sealing component I between the inner ring.

[0006] Furthermore, a groove is provided on the outer side of the outer ring for installing a sealing component II between the outer ring and the lower steamer.

[0007] Furthermore, a stepped through hole is provided in the middle of the outer ring for connecting the booster cylinder and installing the sealing assembly III.

[0008] Furthermore, the sealing component I is composed of a plurality of V-shaped sealing rings stacked together.

[0009] Furthermore, the sealing assembly II includes a pressure plate, a stud, a nut, and a sealing ring.

[0010] Furthermore, the sealing assembly III includes a gland, a sealing gasket, and bolts.

[0011] Compared with the prior art, the advantages and effects of the present invention are:

[0012] 1. The traditional integral lower support plate is split into independent inner and outer rings, so that the maintenance work of the booster cylinder and the center mechanism can be carried out independently. That is, when the booster cylinder needs to be maintained, only the outer ring needs to be removed, and when the center mechanism needs to be maintained, only the inner ring needs to be removed. The two do not affect each other, which greatly simplifies the disassembly steps and greatly reduces the workload and labor intensity of maintenance personnel;

[0013] 2. The sealing component between the inner and outer rings of the combined lower support plate is arranged in the groove on the inner upper edge of the outer ring, which is easier to install and replace. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The present invention will be further described below with reference to the following examples, but the present invention is not limited to these examples.

[0018] The hydraulic vulcanizing press steamer combined lower support plate described in this embodiment is as follows Figure 1 As shown, it consists of an inner ring 1 and an outer ring 2, wherein the inner ring 1 is sleeved on the central mechanism 3 for installing the central mechanism 3, the outer ring 2 is supported by the boosting cylinder 4 and sleeved outside the inner ring 1 for bearing the clamping force of the boosting cylinder 4, the inner ring 1 and the outer ring 2 are connected by screws 6 through a connecting flange 5, and a groove is provided on the inner upper edge of the outer ring 2 for installing a sealing component I between the inner ring 1 to prevent steam leakage on the combined lower support plate. In this embodiment, the sealing component I is composed of a plurality of V-shaped sealing rings 7 stacked together.

[0019] like Figure 2 As shown, the central mechanism is installed on the inner ring 1 of the combined lower support plate, the boosting cylinder 4 is fixed to the countersunk hole of the lower steamer 8 by fastening screws 17, and the piston rod of the boosting cylinder 4 is connected to the outer ring 2 of the combined lower support plate by connecting screws 16. A stepped through hole for installing the connecting screws 16 and the sealing component III is opened in the middle of the outer ring 2. The sealing component III includes a pressure cover 13, a sealing gasket 14, and a bolt 15. The pressure cover 13 and the sealing gasket 14 are pressed tightly by the bolts 15 to ensure that the steam on the lower support plate does not leak from the hole.

[0020] like Figure 2As shown, a groove is provided on the outer side of the outer ring 2 of the combined lower support plate for installing a sealing component II between the lower steamer 8 and the lower steamer 8. The sealing component II includes a pressure plate 9, a stud 10, a nut 11, and a sealing ring 12. The pressure plate 3 is pressed tightly with the stud 4 and the nut 5 to prevent the sealing ring 12 from detaching. The close contact between the sealing ring 12 and the lower steamer 8 ensures that the steam on the lower support plate does not leak.

[0021] The working principle of this embodiment is as follows:

[0022] 1. When the boosting cylinder 4 needs to be maintained, first remove the bolts 15 and the gland 13, then remove the connecting screws 16 that secure the piston rod of the boosting cylinder 4. Then remove the screws 6 and the connecting flange 5 to disengage the outer ring 1 from the inner ring 2. The outer ring 1 can then be lifted out of the vulcanizer from the lower steamer 8. Finally, remove the fastening screws 17 that secure the boosting cylinder 4. The boosting cylinder 4 can then be lifted out of the vulcanizer for maintenance. This eliminates the need to disassemble the central mechanism 3 and related pipelines, greatly reducing maintenance workload.

[0023] 2. When the center mechanism 3 needs to be maintained, it is only necessary to remove the screws 6 and the connecting flange 5 to disengage the outer ring 1 from the inner ring 2. The inner ring 2 can then be disassembled separately. The center mechanism 3 can then be completely disassembled for maintenance without disassembling the outer ring 1.
