Description

Technical Field

[0001] The present invention relates to the field of carbon fiber container processing equipment, and in particular to a bonding and curing device for large-size flange surfaces. Background Art

[0002] After winding processing of a large-volume carbon fiber storage tank (when the maximum diameter of the storage tank generally exceeds 120 cm, it is considered a large-volume carbon fiber storage tank, and the supporting flange is considered a large-size flange), it is necessary to bond and fix the flange on the outer surface to facilitate fixing the entire storage tank through the flange during use. Common shape and structure forms of large-volume carbon fiber storage tanks are as shown in the storage tank form in a method for ensuring the accuracy of the flange shape and installation holes of a propellant storage tank disclosed in Application No. 202211438051.3.

[0003] After bonding and fixing the flange on the outer side of the storage tank, it is necessary to bond and cure the flange and the storage tank in an environment at a specific temperature (between 40°C and 50°C).

[0004] Currently, during the processing, before the flange ring is sleeved on the storage tank, the staff uses an orientation ring to detect and correct the roundness of the flange ring, and moves the flange to the outer side of the storage tank for bonding through a shaping ring. The shaping ring plays a role in keeping the flange fixed during the bonding and curing process.

[0005] Limited by the large size of the flange and shaping and fixing structures such as the shaping ring, it is difficult to move it into a curing furnace for temperature control curing after the flange and the storage tank are sleeved. Therefore, the staff uses a heat-insulating blanket with built-in heating wires to wrap around the outer side of the shaping ring for temperature control curing.

[0006] Using the method of wrapping with a heat-insulating blanket is likely to generate heat leakage points and it is difficult to control the heating position of the heating wires, resulting in uneven circumferential curing temperature distribution of the flange and low heat utilization efficiency. Based on this, the present application proposes a bonding and curing device for large-size flange surfaces. Summary of the Invention

[0028] In the present invention, unless otherwise clearly specified and defined, the terms "mounted", "connected", "coupled", "fixed", etc. should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or integrated; it may be directly connected, or indirectly connected through an intermediate medium, and may be the internal communication of two elements or the interaction relationship between two elements. However, indicating a direct connection means that there is no connection relationship constructed by an excessive structure between the two connected main bodies, and they are only connected through the connection structure to form a whole. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0029] In the present invention, unless otherwise clearly specified and defined, the first feature being "on" or "under" the second feature may be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. In the description of this specification, the description referring to terms such as "one embodiment", "some embodiments", "example", "specific example", or "some examples" means that the specific features, structures, materials, or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the present invention. In this specification, the schematic expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in a suitable manner in any one or more embodiments or examples.

[0030] In the present invention, as Figures 1-4As shown in the figure, a curing device for large-size flange surfaces is provided, including: two fixing frames 1, the two fixing frames 1 are arranged oppositely, and at least one of the fixing frames 1 is arranged to be linearly movable so that the two fixing frames 1 can move away from each other and approach each other; a sizing ring 2, there are two sizing rings 2, the two sizing rings 2 are respectively connected to one fixing frame 1, and a plurality of connecting members 3 are arranged at intervals along the circumferential direction of the sizing ring 2, and the connecting members 3 can be connected to the flange 13 inside the sizing ring 2. When the sizing ring 2 connecting the flange 13 is sleeved outside the storage tank 11, there is a structural gap between the two sizing rings 2; a side baffle, the side baffle can be installed between the sizing ring 2 and the storage tank 11 from the outside of the sizing ring 2, and the side baffle can close the gap between the storage tank 11 and the sizing ring 2, and at least one side baffle at the position of the sizing ring 2 is provided with a heating element 12; a sealing strip 4, the sealing strip 4 is set as an elastic sealing strip 4, and the sealing strip 4 can be filled in the gap between the two sizing rings 2 with an interference fit.

[0031] When the curing device of the present invention is in use, as shown in the figure, after the flange 13 is fixed outside the storage tank 11 through the sizing ring 2, the side baffle can be installed in the gap between the sizing ring 2 and the storage tank 11, and then the sealing strip 4 can be installed between the gaps of the two sizing rings 2, so that a closed space is formed between the storage tank 11 and the sizing ring 2, the side baffle and the sealing strip 4. During the curing process, heat is applied in the closed space through the heating element 12 so that the temperature in the closed space is maintained within a certain range.

[0032] For the bonding and curing device of the present invention, by providing a side baffle, a sizing ring 2, a sealing strip 4 and the storage tank 11 to form a closed space, the problem of unstable temperature control caused by the air flow between the closed space and the outside can be solved. Moreover, when the temperature of the closed space is adjusted through the heating element 12, the temperature in the closed space is more easily adjusted quickly and accurately. The present invention can also prevent the problem of uneven internal temperature distribution caused by the air flow between the closed space and the outside. Moreover, by providing the heating element 12 on the side baffle of the present invention, the position of the heating element 12 in the closed space can be stabilized. Compared with the working condition where the heating wire distribution of the heating blanket in the prior art is affected by the randomness of wrapping, it is easier to control the uniform distribution of the heating element 12 in the closed space in the present invention, and it is also convenient to control the heating intensity of different heating elements 12 to control the local temperature change in the closed space. In addition, the operation of installing the side baffle between the sizing ring 2 and the storage tank 11 and filling the sealing strip 4 between the two sizing rings 2 in the present invention is simple, and it is easier to operate than the method of wrapping the heating blanket.

[0033] For the setting of the sealing strip 4, it is preferably a sealing strip 4 made of heat-insulating rubber material to improve the heat-insulating effect on the closed space.

[0034] It should be noted that the improvement of the present invention lies in the curing device of the flange, and there is no limitation or improvement on the fixing structure of the flange bonding. As one of the embodiments, it is illustrated by way of example in conjunction with the accompanying drawings. The fixing frame 1 is a fixing frame 1 with a frame structure. A sliding shoe is provided at the bottom of the fixing frame 1, and lateral movement is achieved through a track provided on the ground. A sliding shoe cooperating with the track is provided at the bottom of the shaping ring 2. The upper half of the shaping ring 2 is connected to the corresponding fixing frame 1 through a telescopic adjusting rod (connecting member 3). During the curing process, the two shaping rings 2 are connected to each other through the telescopic adjusting rod, so as to maintain the stability of the shaping ring 2 during the curing process. A plurality of telescopic connecting members 3 are circumferentially spaced on the shaping ring 2, and the inner ends of the connecting members 3 are connected to the flange 13 to be bonded (preferably by welding or threaded connection), so that the shaping ring 2 can round and fix the flange 13.

[0035] For a better display of the structural content, in Figure 2 part of the flexible layer and the outer insulation sheet are removed for display.

[0036] In a preferred embodiment, for the structure of the present invention, a further optimized setting is that the side baffle includes a plurality of plate bodies 5 circumferentially spaced along the shaping ring 2 and a flexible layer 6 connected to the plate bodies 5. The flexible layer 6 is set as a heat-insulating flexible layer 6; a connecting portion is provided on the side of the shaping ring 2, the plate bodies 5 can be connected to the connecting portion, and the inner edge of the plate bodies 5 can abut against the storage tank 11. The outer edge of the flexible layer 6 extends to the shaping ring 2, and the inner edge extends to contact the storage tank 11.

[0037] By setting the side baffle in the form of a combination of the plate bodies 5 and the flexible layer 6, the present invention can utilize the plate bodies 5 to realize the installation between the shaping ring 2 and the storage tank 11, utilize the flexible layer 6 to realize the barrier and heat insulation between the gas in the closed space and the outside, and utilize the plurality of separate plate bodies 5 to circumferentially space and fix the flexible layer 6 on the shaping ring 2, so as to easily and stably fix the flexible layer 6, and further maintain the heat insulation effect of the flexible layer 6 on the inner side of the closed space.

[0038] Moreover, the present invention adopts the method of connecting each plate body 5 with the flexible layer 6, which is easy to deform and fold the side baffle, and then it is easy to move the side baffle between the shaping ring 2 and the storage tank 11. Especially in the working condition shown in the figure, when the fixing brackets at both ends of the shaping ring 2 and the storage tank 11 are connected by adjusting rods, the side baffle can be conveniently placed between the adjusting rods, so as to further facilitate the operation.

[0039] For the specific setting method of the flexible layer 6, those skilled in the art can flexibly select the existing heat-insulating layer structure for implementation during implementation.

[0040] To facilitate the installation of the side baffle between the shaping ring 2 and the storage tank 11, preferably, the side baffle is integrally arranged in the circumferential direction of the shaping ring 2 as n separate parts, where n is an integer greater than 1. Each part is respectively provided with a flexible layer 6 and a plurality of plate bodies 5, and the flexible layers 6 between adjacent parts are connected by Velcro. This allows the parts to be inserted through the gap of the adjusting rod between the shaping ring 2 and the fixed bracket for convenient operation. In an alternative embodiment, a side baffle that is integrally annular can also be selected.

[0041] In the illustrated embodiment, for the structure of the present invention, more specifically, as shown in the figure, a slot 7 is provided on one side of the connecting portion facing the midline direction of the storage tank 11. One section of the plate body 5 forms a plug-in portion 501 that can be inserted into the slot 7, and the other section forms a deformable portion 502 that can elastically deform. The deformable portion 502 can elastically abut against the storage tank 11.

[0042] As shown in the figure, during installation, the deformable portion 502 can be compressed and elastically deformed first. During the process of gradually inserting the plug-in portion 501 into the slot 7, the elastic portion gradually returns to its original shape. In this way, the elastic force of the elastic portion can be used to maintain the stable plug-in position of the plug-in portion 501 in the slot 7, so as to further maintain the stability of the flexible layer 6.

[0043] In the illustrated embodiment, for the structure of the present invention, a further optimized setting is that, as shown in the figure, one edge of the flexible layer 6 extends to the outside of the connecting portion and is detachably connected to the shaping ring 2, and the other edge is folded to the inside of the deformable portion 502 to form an inner folded edge.

[0044] In the illustrated embodiment, the outer edge of the flexible layer 6 is connected to the side of the shaping ring 2 by Velcro. By providing the inner folded edge, while the deformable portion 502 is used to keep the position of the plate body 5 stable, the deformable portion 502 can also press the inner edge of the flexible layer 6 against the storage tank 11 to achieve the installation stability of the inner edge position of the flexible layer 6.

[0045] In the illustrated embodiment, a part of the plug-in portion 501 extends out of the outside of the slot 7, and the flexible layer 6 is fixedly connected to the part where the plug-in portion 501 extends to the outside of the slot 7. The flexible layer 6 and the second sub-plate body 5022 are of a split structure, which facilitates adjusting the flatness of the part of the flexible layer 6 pressed by the deformable portion 502 during the installation process.

[0046] In the illustrated embodiment, with respect to the structure of the present invention, more specifically, the deformation part 502 includes a first sub-board body 5021 and a second sub-board body 5022. When the side baffle is installed in the gap between the shaping ring 2 and the storage tank 11, the first sub-board body 5021 is located outside the second sub-board body 5022. The inner edge of the first sub-board body 5021 is turned outward and abuts against the storage tank 11, and the inner edge of the second sub-board body 5022 is turned inward and abuts against the storage tank 11; the heating element 12 is arranged inside the second sub-board body 5022, and the flexible layer 6 is arranged outside the first sub-board body 5021.

[0047] As shown in the figure, by setting the deformation part 502 as two sub-board bodies 5, when the insertion part 501 is inserted into the slot 7, the deformation part 502 is approximately in a V shape, so that the deformation part 502 can stably support and fix the insertion part 501, and further enable the board body 5 to be stably fixed between the shaping ring 2 and the storage tank 11. Moreover, by arranging the flexible layer 6 outside the second sub-board body 5022, it is convenient to arrange and flatten the flexible layer 6 during the installation process, which can further improve the sealing effect of the flexible layer 6 on the enclosed space. By arranging the heating element 12 inside the first sub-board body 5021, the distance between the heating element 12 and the flange 13 can be shortened, and the heating efficiency of the heating element 12 at the position of the flange 13 can be further improved. In addition, the heating element 12 and the flexible layer 6 can be separately arranged, and the heating element 12 is installed on the rigid board body 5, so that it is easier to control the position and state of the heating element 12 in the enclosed space, and further facilitate the control of the heating effect of the heating element 12.

[0048] In the illustrated embodiment, more specifically, as shown in the figure, the first sub-board body 5021 and the second sub-board body 5022 are integrally connected. The length of the first sub-board body 5021 is longer than that of the second sub-board body 5022, and the thickness of the second sub-board body 5022 is greater than that of the first sub-board body 5021; the first sub-board body 5021 and the storage tank 11 clamp the edge of the flexible layer 6.

[0049] By integrally processing the first sub-board body 5021 and the second sub-board body 5022, it is convenient to realize the processing and manufacturing of the deformation part 502. Preferably, the deformation part 502 can be made of materials such as plastic and rubber. After installation, the overall inclination degree of the second sub-board body 5022 is smaller than that of the first sub-board body 5021, and the thickness of the second sub-board body 5022 is greater than that of the first sub-board body 5021. In this way, when the second sub-board body 5022 deforms slightly, it can provide a greater supporting force to the insertion part 501, making the insertion of the insertion part 501 more stable. The first sub-board body 5021 has a smaller thickness and better deformation ability, so that when the flexible layer 6 is clamped between the first sub-board body 5021 and the storage tank 11, the clamping area of the flexible first sub-board body 5021 and the storage tank 11 to the flexible layer 6 can be increased, and further improve the stability and sealing effect of the clamping and fixing of the flexible layer 6.

[0050] During the installation process, the second sub-board body 5022 can be first placed inside the shaping ring 2, and then the insertion part 501 is pressed hard to deform the second sub-board body 5022. After the insertion part 501 moves to the slot 7 position, the insertion part 501 is released. At this time, under the elastic force of the first sub-board body 5021 and the second sub-board body 5022, the insertion part 501 is promoted to be inserted into the slot 7. Then, by pulling up the second sub-board body 5022 outward, the flexible layer 6 is placed between the second sub-board body 5022 and the storage tank 11. The second sub-board body 5022 is more easily pulled up and deformed, so that the position and state of the flexible layer 6 can be adjusted more conveniently. Moreover, during the process of pulling up the second sub-board body 5022, the first sub-board body 5021 with greater supporting ability can keep the insertion part 501 stably inserted.

[0051] For the preferred setting method, the distance between the lower edge of the second sub-board body 5022 and the upper edge of the insertion part 501 in the natural state is H1. After the insertion part 501 is inserted into the slot 7, the distance between the position corresponding to the second sub-board body 5022 on the upper edge of the slot 7 and the storage tank 11 is H2; the distance between the lower edge of the first sub-board body 5021 and the upper edge of the insertion part 501 in the natural state is h1. After the insertion part 501 is inserted into the slot 7, the distance between the position corresponding to the first sub-board body 5021 on the upper edge of the slot 7 and the storage tank 11 is h2. (H1 - H2) is less than (h1 - h2). Preferably, (h1 - h2) is greater than 3 cm, and H1 - H2 is greater than 0 and less than or equal to 2 cm. In this way, the first sub-board body 5021 can have enough length to press the flexible layer 6, and the second sub-board body 5022 can provide stable support to the support body.

[0052] In the illustrated embodiment, for the structure of the present invention, more specifically, as shown in the figure, the curing device includes a side heat insulation plate 8 connected to the side surface of the sizing ring 2, and the connecting portion is provided on the side heat insulation plate 8. As shown in the figure, by providing the side heat insulation plate 8 on the side of the sizing ring 2, it is convenient to process the connecting portion. Moreover, the side heat insulation plate 8 can reduce the heat dissipation of the sizing ring 2 to the outside, thereby further improving the heat utilization efficiency and facilitating the control of the temperature in the enclosed space.

[0053] In the illustrated embodiment, a further optimized setting of the present invention is that the curing device further includes an outer heat insulation sheet 9, and the outer heat insulation sheet 9 can cover the outside of the two sizing rings 2, and the edge of the outer heat insulation sheet 9 is connected to the side heat insulation plate 8 by a magic tape.

[0054] As shown in the figure, by providing the outer heat insulation sheet 9, the outer heat insulation sheet 9 and the side heat insulation plate 8 can be used together to surround the sizing ring 2, thereby further reducing the heat conduction of the sizing ring 2 to the outside, further improving the heat utilization efficiency, and facilitating the control of the temperature in the enclosed space.

[0055] In the embodiment of the present invention, in a preferred embodiment, more specifically, the plate body 5 is integrally formed, and the thickness of the plate body 5 in the deformation portion 502 region is smaller than that in the insertion portion 501 region. As shown in the figure, this can facilitate the processing of the plate body 5. In the illustrated embodiment, the deformation portion 502 is divided into a first sub-plate body 5021 and a second sub-plate body 5022, and the thickness of the first sub-plate body 5021 and the second sub-plate body 5022 is smaller than the thickness of the insertion portion 501, so that the plate body 5 has better elastic deformation ability at the deformation portion 502.

[0056] Alternatively, in an alternative embodiment, it can also be arranged that the insertion portion 501 and the deformation portion 502 of the plate body 5 are of a split structure.

[0057] In a preferred embodiment, for the structure of the present invention, more specifically, the sealing strip 4 is provided with a temperature sensor 10. As shown in the figure, this can make the temperature sensor 10 enter the enclosed space and monitor the temperature at the position between the two sizing rings 2 during the process of installing the sealing strip 4 between the two sizing rings 2, so that the temperature at the flange 13 position can be monitored by the temperature sensor 10 to facilitate the control and adjustment of the temperature in the enclosed space.

[0058] Each embodiment in this specification is described in a progressive manner. The same or similar parts between the embodiments can be referred to each other, and the key points of each embodiment are the differences from other embodiments. In particular, for the system embodiment, since it is basically similar to the method embodiment, the description is relatively simple, and the relevant parts can refer to the partial description of the method embodiment.
