Description

Technical Field

[0001] This application relates to the technical field of sprinkler truck pipe fittings, and in particular to a simple tooling for welding flange connection pipes. Background Technology

[0002] Flange connection pipes (also known in the industry as subsea inlet pipes) are a type of piping accessory for sprinkler trucks. They are mainly installed at the bottom of the sprinkler truck tank to connect various water pipes, thereby achieving purposes such as water diversion. For example... Figure 2 As shown, a flanged pipe generally includes a T-shaped pipe and two flange plates. The flange plates are welded vertically to the opposite ends of the T-shaped pipe, and the T-shaped pipe is made of two mutually perpendicular stainless steel pipes welded together.

[0003] Whether it's welding stainless steel pipes to flange plates or welding two perpendicular stainless steel pipes, the weld seam is basically a ring structure. Therefore, during the welding and assembly of flange connecting pipes, if the welder remains stationary, the direction of the flange connecting pipes needs to be constantly adjusted.

[0004] Regarding the aforementioned technologies, the inventors believe that the following technical defects exist and require improvement:

[0005] Currently, there are virtually no tooling available on the market that can help keep flange connecting pipes rotating easily and stably, resulting in low production efficiency for flange connecting pipes. Utility Model Content

[0037] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.

[0038] This application discloses a simple tooling for welding flanged pipes. (Refer to...) Figure 1-2 The simple welding fixture for flange connection pipes includes a table frame 1, a welding table 2, a welding column 3, a rotating seat 4, and a lifting adjustment component 5. The welding table 2 is fixed on the table frame 1. The welding column 3 is vertically slidably mounted on one corner of the welding table 2. The rotating seat 4 is rotatably connected through the welding column 3 and rests on the welding table 2. The lifting adjustment component 5 is installed on the welding table 2 and is used to adjust the height of the welding column 3. The stainless steel pipe 100 and / or flange plate 200 to be welded are fitted onto the welding column 3 and supported by the rotating seat 4. The length of the top of the welding column 3 protruding from the top of the rotating seat 4 is between 15 and 50 centimeters.

[0039] In this embodiment, the rotating seat 4 includes a rotating cylinder 41, an upper flange 42, and a lower flange 43. The upper flange 42 is fixed to the top of the rotating cylinder 41, and the lower flange 43 is fixed to the bottom of the rotating cylinder 41 and fits against the upper surface of the welding table 2. The rotating seat 4 also includes a bearing 44, which is installed between the welding column 3 and the inner peripheral wall of the rotating cylinder 41. The rotating seat 4 also includes a rubber ring gasket 45, which is bonded to the upper surface of the upper flange 42.

[0040] The rotating seat 4 designed above not only has low rotational resistance and can rotate smoothly, but the rubber ring gasket 45 also has a buffering and protective effect, effectively preventing the stainless steel pipe 100 and / or flange plate 200 from being scratched by impact.

[0041] In this embodiment, the lifting adjustment component 5 includes a height adjustment base plate 51 and a rotating assembly. The rotating assembly is arranged vertically and rotatably mounted on the welding table 2. The height adjustment base plate 51 is located below the welding table 2. The bottom of the welding column 3 is fixed to one end of the height adjustment base plate 51, and the bottom of the rotating assembly is rotatably connected to the other end of the height adjustment base plate 51.

[0042] The rotating assembly includes a threaded rod 52 and a rotating disk 53. The rotating disk 53 is vertically connected to the top of the threaded rod 52. The threaded rod 52 is arranged vertically and threadedly assembled onto the welding table 2. Specifically, a T-shaped block 54 is provided at the bottom of the threaded rod 52, and a connecting seat 55 is provided on the height adjustment base plate 51. The T-shaped block 54 is rotatably assembled into the connecting seat 55. Furthermore, a stainless steel threaded sleeve 6 is provided on the welding table 2, and the threaded rod 52 is threadedly assembled into the threaded sleeve 6.

[0043] The lifting adjustment component 5 designed above can stably drive the threaded rod 52 to rotate, and the operation and adjustment are also relatively convenient. In addition, by raising the base plate 51, the distance between the rotating component and the welding column 3 is increased, thereby freeing up a larger welding operation space, making it very convenient to use.

[0044] In order to enable the welded flange connection pipe to cool down quickly, a cooling box 7 is also installed below the welding table 2. The cooling box 7 is filled with welding coolant. After the flange connection pipe is formed, it can be placed directly into the cooling box 7.

[0045] The beneficial technical effects of the simplified welding fixture for flange connecting pipes in this application are roughly as follows:

[0046] During welding, the stainless steel pipe 100 and / or flange plate 200 to be welded can be fitted onto the welding column 3. Due to the support and flexible rotation of the rotating seat 4, the stainless steel pipe 100 and / or flange plate 200 can be rotated conveniently and stably, so that the welding worker can weld a circumferential weld while staying in a fixed position. This significantly improves the production efficiency of flange connection pipes. Moreover, depending on the size of the accessories, the height of the welding column 3 can be adjusted by the lifting adjustment component 5, so that stainless steel pipes 100 of different lengths can be fitted onto the welding column 3, greatly improving flexibility and practicality.

[0047] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
