[0002] In the power equipment and related fields, corrugated oil tanks are an important component and are widely used in various transformers and other equipment. Their structure and manufacturing process directly affect the performance and quality of the equipment.
[0003] The existing corrugated fuel tank blanking and production structure employs some traditional processes and structural forms in the manufacturing process. For the tank edge structure, the current method is to cut the tank edge separately, then splice and weld the tank edge together, and finally grind it. As for the welding of the tank bottom and tank wall, the tank wall and tank bottom are first assembled and welded according to the drawings based on the marked lines.
[0004] However, the existing corrugated fuel tank structure and manufacturing process have significant drawbacks. The welding of the tank rims is a complex process, requiring multiple steps including material preparation, welding, and grinding. This not only increases production time and costs but also makes it difficult to guarantee the flatness of the welded product due to the multiple operations, thus affecting the overall quality and appearance of the fuel tank. Assembling the tank bottom and walls requires marking lines before alignment, a complex process demanding a high level of skill from workers. Even slight deviations in worker operation can lead to inaccurate assembly of the tank bottom and walls, affecting the tank's sealing and stability. Furthermore, the complex process hinders production efficiency and makes it difficult to meet the growing market demand. Utility Model Content

[0019] The following detailed description illustrates the specific implementation method:
[0020] The markings in the accompanying drawings of the instruction manual include: oil tank body 1, oil sample valve 101, corrugated plate assembly 2, tank edge 3, tank cover assembly 4, hanging plate 401, thermometer tube 402, oil level gauge seat 403, tank bottom assembly 5, bottom plate 501, tank foot 502, and plug 503.
[0021] Corrugated oil tanks are commonly used in various types of transformers. However, the following defects exist in the existing welding and cutting process for corrugated oil tanks:
[0022] Firstly, the material for the box edge 3 is cut separately, and then spliced, welded, and polished. Figure 5 As shown;
[0023] Secondly, the welding of the bottom plate 501 in the tank bottom assembly 5 to the tank wall of the tank body 1 involves marking lines according to the drawings and then assembling and welding the tank wall and bottom plate 501 according to the marked lines. This process is complex, involving multiple steps. Figure 6 As shown.
[0024] In this regard, the welding and blanking structure of a corrugated oil tank according to this application is basically as shown in the attached figure. Figure 1 As shown: It includes a fuel tank body 1, a corrugated sheet assembly 2, a tank edge 3, a tank cover assembly 4, and a tank bottom assembly 5. The corrugated sheet assembly 2 is disposed on the front, rear, left, and right sides of the fuel tank body 1. In this embodiment, the fuel tank body 1 is rectangular, with the front and rear sides being the long sides and the left and right sides being the short sides. There are 9 corrugated sheets on the short sides and 18 corrugated sheets on the long sides. One end of the corrugated sheet is fixed to the corrugated plate, and the other end is fixed by round steel bars at the top and bottom. The corrugated plate is then fixed to the fuel tank body 1, thereby fixing the corrugated sheet assembly 2 to the fuel tank body 1.
[0025] The fuel tank body 1 in this application is constructed of several steel plates, such as Figure 2 As shown, the interior of the oil tank body 1, which is constructed from multiple steel plates, is hollow, and an oil outlet is opened at the bottom of its side wall. An oil sample valve 101 is installed at the oil outlet to facilitate oil sample testing.
[0026] The tank edge 3 and the tank cover assembly 4 are located on top of the tank body 1, wherein, as Figure 2 As shown, the tank edge 3 is formed by one-time laser cutting. The tank edge 3 has the same shape as the top of the tank body 1, with a hollow center and multiple mounting holes. It is fixed to the top of the tank body 1 by bolts and to the tank cover assembly 4. Figure 3As shown, the tank cover assembly 4 includes a tank cover, several hanging plates 401, a thermometer tube 402, and an oil level gauge base 403. The tank cover has several mounting holes. The hanging plates 401, thermometer tube 402, and oil level gauge base 403 are fixed to the top of the tank cover through the mounting holes. The thermometer base provides a channel for the thermometer to be installed and inserted, and the oil level gauge base 403 provides a mounting base for the oil level gauge. In this embodiment, the thermometer tube 402 allows the temperature sensing element of the thermometer to fully contact the oil in the tank, thereby accurately measuring the temperature of the oil in the corrugated tank. The oil temperature can directly reflect the internal losses and heat generation of the transformer, thus alerting the operators to detect abnormalities in the transformer in a timely manner. The oil level gauge base 403 ensures that the oil level gauge can accurately measure and display the oil level in the tank.
[0027] Box bottom assembly 5 includes a bottom plate 501, box feet 502, plugs 503, and plug seats, wherein, as Figure 4 As shown, the bottom plate 501, like the tank edge 3, is formed by laser cutting in one step. This reduces processing steps and ensures dimensional accuracy. At the same time, the dimensions of the bottom plate 501 are consistent with the edge dimensions of the bottom of the tank body 1. When the tank body 1 is welded to the bottom plate 501, a through hole is opened on the bottom plate 501, and the plug seat is fixed in the through hole, for example, by tightening or welding. The plug 503 matches the plug seat. In this embodiment, the function of the plug 503 is to discharge impurities in the corrugated tank.
[0028] The box feet 502 are two in number and are made of channel steel, such as Figure 4 As shown, two tank feet 502 are welded to the bottom plate 501 to support the tank body 1. In order to enhance the stability of the support of the tank feet 502, multiple corner plates are welded and fixed at the welding point between the tank feet 502 and the bottom plate 501. The corner plates act as reinforcing ribs in this application, which can enhance the stability of the tank feet 502.
