Description

Technical Field

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

[0002] Large-volume carbon fiber tanks (tanks with a maximum diameter of more than 120 cm are considered large-volume carbon fiber tanks, and the matching flanges are considered large-size flanges) need to be bonded and fixed to the surface after winding, so as to facilitate fixing the entire tank through the flange during use. Common shapes and structures of large-volume carbon fiber tanks are shown in the method for ensuring the flange shape and mounting hole accuracy of a propellant tank disclosed in application number 202211438051.3.

[0003] After the flange is bonded and fixed to the outside of the tank, the flange and the tank need to be bonded and cured in a specific temperature environment (between 40 degrees and 50 degrees).

[0004] Currently, during the processing, workers use an orienting ring to detect and correct the roundness of the flange ring before putting it on the tank, and use a shaping ring to move the flange to the outside of the tank for bonding. The shaping ring plays a role in keeping the flange fixed during the bonding and curing process.

[0005] Due to the large size of the flange and fixed structures such as the forming ring, it is difficult to move the flange to the curing furnace for temperature-controlled curing after the flange and the tank are connected. Therefore, the staff uses an insulation blanket with a built-in electric heating wire to wrap the outside of the forming ring for temperature-controlled curing.

[0006] The use of thermal insulation blanket wrapping easily generates heat leakage points and makes it difficult to control the heating position of the heating wire, which leads to uneven circumferential curing temperature distribution of the flange and low heat utilization efficiency. Based on this, the present application proposes a large-size flange surface bonding and curing device. Summary of the invention

[0028] In the present invention, unless otherwise clearly specified and limited, the first feature "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 with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present invention. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples.

[0029] In the present invention, if Figure 1-Figure 4As shown, a large-size flange surface bonding and curing device is provided, comprising: two fixing frames 1, the two fixing frames 1 are arranged opposite to each other, 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 or close to each other; a shaping ring 2, two of the shaping rings 2 are provided, and the two shaping rings 2 are respectively connected to one of the fixing frames 1, and the shaping ring 2 is provided with a plurality of connecting members 3 at intervals along its circumference, and the connecting members 3 can be connected to the flange 13 on the inner side of the shaping ring 2, and the shaping ring 2 is connected to the flange 13. When the flange 13 is mounted on the outside of the tank 11, a structural gap is provided between the two shaping rings 2; a side baffle, the side baffle can be installed between the shaping ring 2 and the tank 11 from the outside of the shaping ring 2, the side baffle can close the gap between the tank 11 and the shaping ring 2, and the side baffle at at least one of the shaping rings 2 is provided with a heating element 12; a sealing strip 4, the sealing strip 4 is configured as an elastic sealing strip 4, and the sealing strip 4 can fill the gap between the two shaping rings 2 with interference.

[0030] When the curing device of the present invention is used, as shown in the figure, after the flange 13 is fixed to the outside of the tank 11 by the shaped ring 2, the side baffle can be installed in the gap between the shaped ring 2 and the tank 11, and the sealing strip 4 can be installed between the gaps of the two shaped rings 2, so that a closed space is formed between the tank 11 and the shaped ring 2, the side baffle, and the sealing strip 4. During the curing process, the closed space is heated by the heating element 12 so that the temperature in the closed space is maintained within a certain range.

[0031] The bonding and curing device of the present invention forms a closed space by setting a side baffle and a shaping ring 2, a sealing strip 4 and a storage tank 11, so as to solve the problem of unstable temperature control caused by the flow of air between the closed space and the outside world, and when the temperature of the closed space is adjusted by the heating element 12, it is easier to quickly and accurately adjust the temperature in the closed space. The present invention can also prevent the problem of uneven internal temperature distribution caused by the flow of air between the closed space and the outside world. Moreover, by setting the heating element 12 on the side baffle, the position of the heating element 12 in the closed space can be stabilized. Compared with the working condition of uneven distribution of heating wires caused by the randomness of the heating blanket in the prior art, the present invention is easier to control the uniform distribution of the heating element 12 in the closed space, 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 present invention is simple to operate by installing the side baffle between the shaping ring 2 and the storage tank 11 and filling the sealing strip 4 between the two shaping rings 2, which is easier to operate than the method of wrapping an additional heat blanket.

[0032] As for the setting of the sealing strip 4, it is preferred to use a sealing strip 4 made of heat-insulating rubber material to improve the heat-insulating effect of the closed space.

[0033] It should be noted that the improvement of the present invention lies in the curing device of the flange, and no restrictive improvement is made to the fixing structure of the flange bonding. As one of the embodiments, it is illustrated in conjunction with the accompanying drawings. The fixing frame 1 adopts a fixing frame 1 of a frame structure, and a sliding shoe is arranged at the bottom of the fixing frame 1, and lateral movement is achieved through a track arranged on the ground. A sliding shoe that cooperates with the track is arranged at the bottom of the shaping ring 2. The upper half of the shaping ring 2 is connected to the fixing frame 1 at the corresponding position through a retractable adjustment rod (connector 3), and the two shaping rings 2 are connected to each other through the retractable adjustment rod during the curing process, so as to maintain the stability of the shaping ring 2 during the curing process. A plurality of retractable connecting members 3 are arranged at intervals in the circumference of the shaping ring 2, and the inner end of the connecting member 3 is connected to the flange 13 to be bonded (preferably by welding or threaded connection), so that the shaping ring 2 can calibrate and fix the flange 13.

[0034] In order to better display the structure content, Figure 2 In the figure, part of the flexible layer and the outer insulation sheet are removed for display.

[0035] 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 arranged at intervals along the circumference of the shaping ring 2, and a flexible layer 6 connected to the plate bodies 5, and the flexible layer 6 is configured as a heat-insulating flexible layer 6; a connecting portion is provided on the side of the shaping ring 2, the plate body 5 can be connected to the connecting portion, and the inner edge of the plate body 5 can abut against the tank 11, and the outer edge of the flexible layer 6 extends to the shaping ring 2, and the inner edge extends to contact with the tank 11.

[0036] The present invention arranges the side baffle plate in a combination of a plate body 5 and a flexible layer 6, so that the plate body 5 can be used to achieve installation between the shaping ring 2 and the storage tank 11, and the flexible layer 6 can be used to achieve isolation and heat insulation between the gas in the closed space and the outside world. A plurality of separate plate bodies 5 can be used to fix the flexible layer 6 at circumferential intervals on the shaping ring 2, so that the flexible layer 6 can be easily fixed flatly and stably, so as to further maintain the thermal insulation effect of the flexible layer 6 on the inside of the closed space.

[0037] Moreover, the present invention adopts the method of connecting each plate body 5 with a flexible layer 6, which makes it easy to deform and fold the side baffle, and then it is easy to move the side baffle to between the shaping ring 2 and the storage tank 11. Especially in the working condition shown in the figure, when the fixing brackets at the two 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, thereby further facilitating the operation.

[0038] As for the specific arrangement of the flexible layer 6, those skilled in the art can flexibly select the existing heat insulation layer structure for implementation.

[0039] In order to facilitate the installation of the side baffle between the shaping ring 2 and the tank 11, the preferred method is that the side baffle is integrally arranged as n divided parts in the circumferential direction of the shaping ring 2, where n is an integer greater than 1. Each part is 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. In this way, the parts can be placed in the gap between the shaping ring 2 and the adjusting rod between the fixing bracket to facilitate operation. In an optional embodiment, a side baffle that is annular as a whole can also be selected.

[0040] 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 centerline direction of the tank 11, one section of the plate body 5 is formed with an insertion portion 501 that can be inserted into the slot 7, and the other section is formed with an elastically deformable deformation portion 502, and the deformation portion 502 can elastically abut against the tank 11.

[0041] As shown in the figure, during installation, the deformation portion 502 is first compressed and elastically deformed, and when the insertion portion 501 is gradually inserted into the slot 7, the elastic portion gradually recovers the deformation, so that the elastic force of the elastic portion can be used to maintain the insertion position of the insertion portion 501 in the slot 7 stable, so as to further maintain the stability of the flexible layer 6.

[0042] 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 deformation portion 502 to form an inner flange.

[0043] In the illustrated embodiment, the outer edge of the flexible layer 6 is connected to the side of the shaping ring 2 by Velcro, and an inner flange is provided, so that the deformation portion 502 can be used to maintain the position of the plate body 5 stable while the inner edge of the flexible layer 6 can be pressed against the storage tank 11 by the deformation portion 502, so as to achieve the installation stability of the inner edge position of the flexible layer 6.

[0044] In the illustrated embodiment, the insertion portion 501 partially extends out of the outside of the slot 7, the flexible layer 6 is fixedly connected to the portion of the insertion portion 501 extending to the outside of the slot 7, and the flexible layer 6 and the second sub-board body 5022 are separate structures, so that it is easy to adjust the flatness of the portion of the flexible layer 6 pressed by the deformation portion 502 during the installation process.

[0045] In the illustrated embodiment, for the structure of the present invention, to be further specific, the deformation portion 502 includes a first sub-plate body 5021 and a second sub-plate body 5022. When the side baffle is installed in the gap between the shaping ring 2 and the tank 11, the first sub-plate body 5021 is located on the outside of the second sub-plate body 5022, the inner edge of the first sub-plate body 5021 is folded outward and abuts against the tank 11, and the inner edge of the second sub-plate body 5022 is folded inward and abuts against the tank 11; the heating element 12 is arranged on the inner side of the second sub-plate body 5022, and the flexible layer 6 is arranged on the outer side of the first sub-plate body 5021.

[0046] As shown in the figure, the present invention sets the deformation part 502 as two sub-plate bodies 5, so that when the insertion part 501 is inserted into the slot 7, the deformation part 502 is roughly in a herringbone shape, so that the deformation part 502 can stably support and fix the insertion part 501, and then the plate body 5 can be stably fixed between the shaped ring 2 and the tank 11. In addition, by setting the flexible layer 6 on the outside of the second sub-plate body 5022, it is convenient to arrange and level the flexible layer 6 during the installation process, so as to further improve the sealing effect of the flexible layer 6 on the closed space. By setting the heating element 12 on the inner side of the first sub-plate 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 on the flange 13 position can be further improved. In addition, the heating element 12 and the flexible layer 6 can be set separately, and the heating element 12 is installed on the rigid plate body 5, which makes it easier to control the position and state of the heating element 12 in the closed space, so as to further facilitate the control of the heating effect of the heating element 12.

[0047] In the illustrated embodiment, further 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 the length of the second sub-board body 5022, and the thickness of the second sub-board body 5022 is greater than the thickness 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.

[0048] By processing the first sub-plate body 5021 and the second sub-plate body 5022 as one body, the processing and manufacturing of the deformation part 502 can be easily realized. Preferably, the deformation part 502 can be made of plastic, rubber or other materials. After installation, the overall inclination of the second sub-plate body 5022 is less than that of the first sub-plate body 5021, and the thickness of the second sub-plate body 5022 is greater than that of the first sub-plate body 5021, so that the second sub-plate body 5022 can provide a greater supporting force to the insertion part 501 under a small deformation, making the insertion of the insertion part 501 more stable. The first sub-plate body 5021 has a smaller thickness and better deformation ability, so that when the first sub-plate body 5021 and the storage tank 11 clamp the flexible layer 6, the area of ​​the flexible first sub-plate body 5021 and the storage tank 11 clamping the flexible layer 6 can be increased, further improving the stability and sealing effect of clamping and fixing the flexible layer 6.

[0049] During the installation process, the second sub-board body 5022 can be first placed inside the sizing ring 2, and then the second sub-board body 5022 can be deformed by pressing the insertion part 501. After the insertion part 501 moves to the position of the slot 7, the insertion part 501 is released. At this time, the insertion part 501 is promoted to be inserted into the slot 7 under the elastic force of the first sub-board body 5021 and the second sub-board body 5022. 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 box 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, in the process of pulling up the second sub-board body 5022, the first sub-board body 5021 with greater support capacity can keep the insertion part 501 stably inserted.

[0050] For the preferred arrangement, 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, and after the insertion part 501 is inserted into the slot 7, the distance between the position of the second sub-board body 5022 corresponding to 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, and after the insertion part 501 is inserted into the slot 7, the distance between the position of the first sub-board body 5021 corresponding to 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, H1-H2 is greater than 0 and less than or equal to 2 cm, so that the position of 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.

[0051] In the illustrated embodiment, for the structure of the present invention, further specifically, as shown in the figure, the curing device includes a side insulation board 8 connected to the side of the sizing ring 2, and the side insulation board 8 is provided with the connection portion. As shown in the figure, by providing the side insulation board 8 on the side of the sizing ring 2, the connection portion can be easily processed, and the side insulation board 8 can reduce the heat dissipated outward by the sizing ring 2, thereby further improving the heat utilization efficiency and conveniently controlling the temperature in the closed space.

[0052] In the illustrated embodiment, a further optimized arrangement of the present invention is that the curing device also includes an external insulation sheet 9, which can cover the outer sides of the two shaping rings 2, and the edge of the external insulation sheet 9 is connected to the side insulation board 8 by Velcro.

[0053] As shown in the figure, by setting up an external insulation sheet 9, the external insulation sheet 9 and the side insulation plate 8 can be used to surround the shaping ring 2, so as to further reduce the heat conducted to the outside by the shaping ring 2, further improve the heat utilization efficiency, and facilitate the control of the temperature in the closed space.

[0054] In the embodiment of the present invention, in a preferred embodiment, further specifically, the plate body 5 is integrally formed, and the thickness of the plate body 5 in the deformation portion 502 area is less than that in the insertion portion 501 area, as shown in the figure, so that it is convenient to process 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 less than that of the insertion portion 501, so that the plate body 5 has better elastic deformation ability at the deformation portion 502 position.

[0055] Alternatively, in an optional embodiment, it may be arranged that the inserting portion 501 and the deformation portion 502 of the plate body 5 are separate structures.

[0056] 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, the sealing strip 4 can be installed between the two shaped rings 2 so that the temperature sensor 10 enters the closed space and monitors the temperature at the position between the two shaped rings 2. In this way, 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 closed space.
