DETAILED DESCRIPTION

[0030] Typical embodiments that embody the features and advantages of the present invention will be described in detail in the following description. It should be understood that the present invention can have various changes in different embodiments without departing from the scope of the present invention, and the descriptions and illustrations therein are essentially for illustrative purposes rather than for limiting the present invention.

[0031] In the description of the present application, it should be understood that in the embodiments shown in the drawings, the indications of directions or positional relationships (such as up, down, left, right, front and back, etc.) are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the devices or elements referred to must have a specific orientation, be constructed and operate in a specific orientation. These descriptions are appropriate when these elements are in the positions shown in the drawings. If the descriptions of the positions of these elements change, the indications of these directions also change accordingly.

[0032] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0033] This embodiment provides a new type of tank body support tooling for assisting the welding of special-shaped tank bodies. The tank body is generally first rolled from steel plates, and the welds need to be manually welded after rolling. During the welding process, the tank body is prone to deformation, which has a certain impact on the quality of the tank body and will cause subsequent complicated rectification. Therefore, a tank body support tooling is needed to improve the deformation problem of the tank body during the welding process. The specific solution is explained through the following embodiments.

[0034] It should be noted that the irregularly shaped tank body refers to a tank body whose cross section is not a perfect circle, and the cross section of the irregularly shaped tank body can be an ellipse, a rectangular circle or other shapes formed by combining multiple arcs. In this embodiment, the cross section of the tank body is one of the shapes formed by combining multiple arcs as an example.

[0035] See also Figure 1 As shown, the shape of the inner support fixture of the tank body in this embodiment is the same as the shape of the cross section of the tank body.

[0036] The inner support tooling of the tank body comprises an upper die 1 and a lower die 2. The upper die 1 and the lower die 2 comprise a main body section and extension sections arranged at both ends of the main body section, and a smooth transition is provided between the main body section and the extension section.

[0037] For ease of description, the main body section and the extension section of the upper mold 1 are defined as a first main body section 11 and a first extension section 12 , and the main body section and the extension section of the lower mold 2 are defined as a second main body section 21 and a second extension section 22 .

[0038] In this embodiment, the curvature of the first main body section 11 is smaller than the curvature of the second main body section 21. It should be noted that in other embodiments, the curvatures of the first main body section 11 and the second main body section 21 can be set according to the actual shape of the can body. In other words, the curvatures of the upper mold 1 and the lower mold 2 are customized according to the cross-sectional shapes of different can bodies to achieve the best welding effect.

[0039] See also Figure 2 , the upper die 1 and the lower die 2 include a plurality of arc segments. It should be noted that, in other embodiments, the upper die 1 and / or the lower die 2 may also be an integral structure.

[0040] In this embodiment, the number of arc segments of the upper mold 1 and the lower mold 2 is two respectively. For the convenience of description, the arc segments of the upper mold 1 are defined as the first arc segment 13 and the second arc segment 14, and the arc segments of the lower mold 2 are defined as the third arc segment 23 and the fourth arc segment 24. The first arc segment 13 and the second arc segment 14 are symmetrically arranged, and the third arc segment 23 and the fourth arc segment 24 are symmetrically arranged for easy installation.

[0041] Adjacent arc segments are connected by fasteners 3. Take the above mold 1 as an example, see Figures 3 to 6 , two mounting holes 4 are formed on one side of the first arc segment 13 close to the second arc segment 14. Correspondingly, two mounting holes 4 are also formed on one side of the second arc segment 14 close to the first arc segment 13. Two fasteners 3 pass through the mounting holes 4 on the first arc segment 13 and the mounting holes 4 on the second arc segment 14, respectively, so as to fasten and connect the adjacent arc segments.

[0042] The structure of the lower die 2 is the same as that of the upper die 1, see Figures 8 to 11 The third arc segment 23 has two mounting holes 4 on one side close to the fourth arc segment 24. Correspondingly, the fourth arc segment 24 has two mounting holes 4 on one side close to the third arc segment 23. The two fasteners 3 pass through the mounting holes 4 on the third arc segment 23 and the mounting holes 4 on the fourth arc segment 24, respectively, so as to fasten and connect the adjacent arc segments.

[0043] Preferably, the fastener 3 can adjust the distance between adjacent arc segments, so as to facilitate the upper mold 1 and the lower mold 2 to fit closely to the inner wall of the can body. In addition, such a design also enables the can body support tool to be used for can bodies of different sizes but similar cross-sectional shapes, thereby improving the flexibility of use of the can body support tool.

[0044] Continue to see Figure 2 The upper mold 1 and the lower mold 2 are detachably connected to facilitate installation and disassembly. The shape of the upper mold 1 and the lower mold 2 after being connected is the same as the shape of the cross section of the can body.

[0045] The upper mold 1 and the lower mold 2 are connected by a connecting member 6. Specifically, the upper mold 1 is provided with a first connecting portion 15 at both ends, and the lower mold 2 is provided with a second connecting portion 25 at both ends. The first connecting portion 15 and the second connecting portion 25 are opposite to each other, and there is a spacing 7 between the first connecting portion 15 and the second connecting portion 25. The spacing 7 can be adjusted by adjusting the connecting member 6, so that the outer periphery of the upper mold 1 and the lower mold 2 are respectively closely fitted with the inner wall of the can body, forming a stable support for the can body, and effectively preventing the can body from being deformed.

[0046] For further information, see Figures 2 to 4 , Figures 7 to 9 as well as Fig.12As shown, the first connection part 15 is provided with a first connection hole 151, and the second connection part 25 is provided with a second connection hole 251. The connection member 6 is a bolt, which passes through the first connection hole 151 and the second connection hole 251 respectively. A nut is provided on one side of the first connection part 15 close to the second connection part 25, and a nut is also provided on one side of the second connection part 25 close to the first connection part 15. The nut cooperates with the bolt to adjust the distance 7 between the upper mold 1 and the lower mold 2.

[0047] Please continue reading Figure 1 Preferably, the lower mold 2 includes two webs 26 and a plurality of reinforcing plates 27. The two webs 26 are parallel and spaced apart and are respectively perpendicular to the inner wall of the tank body. The plurality of reinforcing plates 27 are spaced apart between the two webs 26, and the two ends of each reinforcing plate 27 are respectively perpendicular to each web 26, which is not only conducive to enhancing the structural strength, but also conducive to enhancing the stability and supporting capacity of the tooling.

[0048] The structures of the upper mold 1 and the lower mold 2 are basically the same, and also include two webs 26 and a plurality of reinforcing plates 27 disposed between the two webs 26 , which will not be described in detail herein.

[0049] Preferably, the tank body support tooling also includes a curved pad (not shown in the figure). The inner curved surface of the pad fits with the outer periphery of the upper mold 1 and the lower mold 2, and the outer curved surface of the pad fits with the inner wall of the tank body, thereby protecting the inner wall of the tank body and ensuring that the inner wall of the tank body is not scratched after concentrated squeezing, thereby further improving the welding quality.

[0050] Preferably, along the central axis direction of the tank body, the width of the pad is greater than the width of the upper mold 1 and the lower mold 2, further increasing the contact area with the inner wall of the tank body, which is beneficial to the stable support of the tank body while further protecting the inner wall of the tank body.

[0051] The specific implementation method of the tank body support tooling is:

[0052] According to the shape and size of the required tank cross section, the webs 26 of the upper mold 1 and the lower mold 2 are cut out by laser. The webs 26 are then welded to a plurality of reinforcing plates 27, and processed to form the upper mold 1 and the lower mold 2 according to the above structural description. The upper mold 1 and the lower mold 2 are placed inside the tank after preliminary rolling, and then the connector 6 is installed and adjusted so that the outer periphery of the upper mold 1 and the lower mold 2 fits tightly with the inner wall of the tank, and then the tank can be welded by girth welding or seam welding. After the welding operation is completed, the tank body support tooling can be disassembled.

[0053] During the tank body welding process, the tank body support fixture provides support and positioning for the tank body, ensuring that the shape of the tank body will not change during the welding process. This effectively reduces welding errors, improves welding quality, and can complete the expected tank body design, ensure the tank body contour and tank body volume, and improve the finished product rate of tank body production.

[0054] It should be noted that the number of tank body support fixtures used during use should be set according to the designed length of the tank body and the thickness of the tank wall. For example, if the tank wall is thin, more tank body support fixtures are required; if the tank wall is thick, a small number of tank body support fixtures can be used.

[0055] It can be seen from the above technical solution that the tank body inner support tooling provided in this embodiment has the following advantages and beneficial implementation effects.

[0056] The detachable connection between the upper die 1 and the lower die 2 facilitates installation and disassembly, and has the advantage of convenient operation. The connecting piece 6 connecting the upper die 1 and the lower die 2 can also adjust the distance 7 between the upper die 1 and the lower die 2, and the distance between the multiple arc segments constituting the upper die 1 and the lower die 2 can also be adjusted, which is not only more conducive to the close fit of the tank body support device to the inner wall of the tank body, effectively preventing the deformation of the tank body during the welding process, but also enables the tank body support tool to be used for tank bodies of different sizes but similar cross-sectional shapes, thereby improving the flexibility of use of the tank body support tool.

[0057] The structural arrangement of the upper die 1 and the lower die 2, that is, the arrangement of the web 26 and the reinforcing plate 27, enhances the structural strength, which is conducive to the tank body inner support tooling of this embodiment to form a stable support for the tank body. The arrangement of the pad is conducive to the protection of the inner wall of the tank body.

[0058] The above embodiments are merely exemplary descriptions of the structures. The structures in the embodiments are not fixed combination structures. In the absence of structural conflicts, the structures in multiple embodiments can be used in any combination.

[0059] Although the utility model has been described with reference to several typical embodiments, it should be understood that the terms used are illustrative and exemplary, rather than restrictive. Since the utility model can be implemented in a variety of forms without departing from the spirit or essence of the utility model, it should be understood that the above-mentioned embodiments are not limited to any of the aforementioned details, but should be widely interpreted within the spirit and scope defined by the attached claims, so all changes and modifications falling within the scope of the claims or their equivalents should be covered by the attached claims.
