Description

Technical Field

[0001] This utility model relates to the technical field of tire vulcanizing machine structure, and in particular to a novel vulcanizing steam chamber for a hydraulic tire vulcanizing machine. Background Technology

[0002] Currently, the commonly known vulcanizing steam chamber consists of an upper vulcanizing chamber and a lower vulcanizing chamber combined into a sealed space. Tire manufacturers use their own vulcanization processes to introduce steam or nitrogen or other media into the sealed vulcanizing chamber, maintaining pressure and heating to achieve the conditions for tire vulcanization. During vulcanization, a bladder is placed inside the tire blank, and high-pressure steam is injected into the bladder. The expansion pressure of the bladder forces the outer tire blank to fill the mold. The outer tire vulcanization employs a gradual heating and low-temperature, long-duration vulcanization method to ensure sufficient flow and heat transfer of the rubber compound, thus ensuring vulcanization quality.

[0003] In the existing technology, the connection between the lower vulcanizing chamber and the base needs to be made by a large clamp. Since the diameter of the connection between the lower vulcanizing chamber and the base is very large, the connection method of the two by the large clamp increases the cost, the overall weight increases significantly, and the operation of centering and positioning is more difficult. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a new type of vulcanizing steam chamber for a hydraulic tire vulcanizing machine. By improving the connection structure between the lower vulcanizing chamber and the base, the problem of increased cost, significantly increased overall weight, and difficult centering and positioning caused by the need for a large clamp to connect the lower vulcanizing chamber and the base in the prior art is solved.

[0037] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0038] Please refer to Figures 1 to 10 The specific embodiments of this utility model relate to a novel vulcanizing steam chamber for a hydraulic tire vulcanizing machine, comprising:

[0039] The lower vulcanizing chamber 1 has an annular connecting part 11 at its lower end, and a plurality of first toothed parts 12 arranged in a circumferential array on the inner side of the annular connecting part 11.

[0040] The base 2 has multiple second toothed members 21 arranged in a circular array on the outer edge of its upper edge. The outer diameter of the second toothed member 21 is smaller than the inner diameter of the annular connecting part, and the outer diameter of the second toothed member 21 is larger than the inner diameter of the first toothed member 12. The second toothed member 21 and the first toothed member 12 are misaligned. The outer side of the base 2 has an annular protrusion 22, and the distance between the annular protrusion 22 and the second toothed member 21 is greater than the height of the first toothed member 12. The circumferential surface of the annular protrusion 22 has one or more limiting grooves 23.

[0041] The wedge-shaped shim assembly 3 includes a first wedge block 31 and a second wedge block 32. The inclined surfaces of the first wedge block 31 and the second wedge block 32 are connected by frictional engagement. The wedge-shaped shim assembly 3 is disposed on the upper part of the annular convex edge 22.

[0042] The centering adjustment assembly 4 is a plurality of centering adjustment assemblies 4 arranged in a circumferential array and connected to the lower part of the annular connecting part 11. The centering adjustment assembly 4 includes an adjustment support 41, a first bolt 42 and a nut 43. The adjustment support 41 is connected to the bottom of the annular connecting part 11 and has a first threaded hole. The head of the first bolt 42 faces outward and is threaded into the first threaded hole. The nut 43 is threaded into the first bolt 42 and is located between the bolt head and the first threaded hole.

[0043] The anti-rotation bracket 5 includes a limiting plate 51 and a connecting plate 52 that are perpendicularly connected to each other. The limiting plate 51 is in transition fit or clearance fit with the limiting groove 23. The connecting plate 52 is provided with two or more through holes 521. The lower part of the annular connecting part 11 is provided with a second threaded hole corresponding to the through holes 521.

[0044] In the assembled state, the upper part of the first toothed member 12 abuts against the lower part of the second toothed member 21, the wedge-shaped shim assembly 3 is connected between the lower part of the first toothed member 12 and the upper part of the annular protrusion 22; the end of the first bolt 42 abuts against the circumferential surface of the annular protrusion 22; the limiting plate 51 of the anti-rotation bracket 5 is limited and fitted in the limiting groove 23; the second bolt 53 passes through the through hole 521 and is connected to the second threaded hole.

[0045] In the above embodiments, the assembly process of the vulcanizing steam chamber is as follows:

[0046] The lower vulcanizing chamber 1 is hoisted above the base 2, and the angle of the lower vulcanizing chamber 1 is adjusted so that the positions of the first toothed part 12 and the second toothed part 21 are misaligned.

[0047] The vulcanizing chamber 1 is moved downward under control, so that the first toothed part moves below the second toothed part 21;

[0048] The vulcanizing chamber 1 is rotated under control, causing the first toothed part 12 to rotate to abut against the lower part of the first toothed part 12; the connecting plate 52 of the anti-rotation bracket 5 is locked into the through hole 521 of the connecting plate 52 and the second threaded hole of the annular connecting part 11 by the second bolt 53, so that the limiting plate 51 of the anti-rotation bracket 5 is limited and matched in the limiting groove 23 of the annular protrusion 22;

[0049] The first bolt 42 of the centering adjustment component 4 is rotated, and the first bolt 42 abuts against the annular protrusion 22 of the base 2, so that the lower vulcanizing chamber 1 is adjusted to a position where the axis of the base 2 coincides.

[0050] The vulcanizing chamber 1 is pulled upward under control, so that the first toothed part 12 is tightly attached to the lower part of the second toothed part 21;

[0051] A wedge-shaped shim assembly 3 is placed in the gap between the annular protrusion 22 and the circular connecting part 11. The overall height of the wedge-shaped shim assembly 3 is adjusted by adjusting the inclined mating parts of the first wedge block 31 and the second wedge block 32, so that the wedge-shaped shim assembly 3 is supported in the gap between the annular protrusion 22 and the circular connecting part 11; thus completing the positioning connection between the lower vulcanizing chamber 1 and the base 2.

[0052] The interlocking structure of the first toothed part 12 and the second toothed part 21, combined with the anti-rotation bracket 5, the centering adjustment component 4 and the wedge-shaped padding component 3 with specific structure and positional relationship, can replace the original structure of using a large clamp to hold the lower vulcanizing chamber 1 and the base 2. It has better stability, simpler centering and positioning operation, and can effectively prevent relative rotational displacement between the lower vulcanizing chamber 1 and the base 2. Since the large clamp structure is omitted, the overall weight of the vulcanizing steam chamber caused by the large clamp is reduced, saving material costs.

[0053] In the above embodiments, the first wedge block 31 and the second wedge block 32 are made of metal, preferably iron. The inclined surfaces of the first wedge block 31 and the second wedge block 32 are provided with anti-slip material layers. The upper inclined surface of the first wedge block 31 and the lower inclined surface of the second wedge block 32 are connected by friction through the anti-slip material layers.

[0054] In a preferred embodiment, an upper vulcanizing chamber 6 is also included, the lower edge of the upper vulcanizing chamber 6 and the upper edge of the lower vulcanizing chamber 1 are connected by a locking ring 7, and lifting lugs 8 are respectively connected to both sides of the upper vulcanizing chamber 6.

[0055] In the above embodiments, the lower vulcanizing chamber 1 can be moved by the lifting lug 8 of the upper vulcanizing chamber 6 through the action of the hook.

[0056] In a preferred embodiment, the upper edge of the lower vulcanizing chamber 1 is provided with an annular first sealing ring 13 and a second sealing ring 14.

[0057] In the above embodiments, by setting two layers of sealing rings at the connection between the lower vulcanizing chamber 1 and the upper vulcanizing chamber 6, the pressure holding capacity of the vulcanizing steam chamber is improved and the heat loss in the vulcanized tire is reduced, thereby achieving the effect of energy saving.

[0058] In a preferred embodiment, both the inner and outer walls of the lower vulcanizing chamber 1 are provided with heat insulation covers 15. This further improves the pressure holding capacity of the vulcanizing steam chamber and reduces heat loss in the vulcanized tire.

[0059] In a preferred embodiment, the upper part of the adjusting support 41 is provided with a threaded post 411, and the lower part of the annular connecting part 11 is connected to a third threaded hole that matches the threaded post 411. The threaded post 411 is threadedly connected to the third threaded hole.

[0060] In the above embodiments, the advantage of adjusting the support 41 being threadedly connected to the annular connecting part 11 via the threaded post 411 is that, firstly, the adjustment support 41 can be flexibly disassembled and assembled at the lower part of the annular connecting part 11; secondly, the tilt angle of the first bolt 42 can be appropriately adjusted according to the need for fine-tuning, so as to better achieve the positional fine-tuning function between the lower vulcanizing chamber 1 and the base 2.

[0061] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent modifications made based on the content of this utility model specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of this utility model.
