Description

Technical Field

[0001] This utility model relates to the field of silicon steel sheet technology for transformers, and specifically to a silicon steel sheet that can limit movement. Background Technology

[0002] Silicon steel sheets, also known as oriented silicon steel or electrical steel, are a type of low-carbon steel containing a certain proportion of silicon. They are primarily used as core materials in electrical equipment such as motors, transformers, and generators, and have significant application value. In some large transformers, the silicon steel sheets are assembled piece by piece using vertical and horizontal silicon steel plates.

[0003] Currently, the assembly of silicon steel sheets for large transformers involves pre-reserving a V-shaped groove on the vertical silicon steel plate and a V-shaped platform at each end of the horizontal silicon steel plate. Two vertical silicon steel plates are then placed parallel to each other on a support base, followed by three horizontal silicon steel plates placed horizontally between the two vertical plates. These are then glued together to secure the assembly. While this method enables the assembly of silicon steel sheets for large transformers, the lack of effective horizontal restraint on the vertical and horizontal silicon steel plates during assembly makes the sheets prone to loosening and tilting due to accidental collisions. This results in relatively low assembly efficiency for the silicon steel sheets used in transformers. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] The technical problem to be solved by this utility model is to provide a silicon steel sheet that can effectively limit the position between the silicon steel vertical plate and the silicon steel horizontal plate during the assembly process, so as to avoid the silicon steel vertical plate and the silicon steel horizontal plate becoming loose and skewed during the assembly process, and has high assembly efficiency.

[0006] (II) Technical Solution

[0007] This utility model is achieved through the following technical solution: This utility model proposes a silicon steel sheet with limiting function, including two silicon steel vertical plates arranged in parallel, and three silicon steel horizontal plates installed in parallel between the two silicon steel vertical plates. Each silicon steel vertical plate has an assembly groove at its upper end that mates with the silicon steel horizontal plate. A limiting insertion hole is reserved at the bottom end of the assembly groove. Both ends of the silicon steel horizontal plate have assembly platforms that mate with the assembly grooves on the two silicon steel vertical plates. A limiting insertion post is installed at the center of the bottom end of the assembly platform.

[0008] Furthermore, a retaining strip is installed on the upper end of the silicon steel vertical plate located on one side of the assembly groove, and a retaining groove is provided on the bottom end of the silicon steel vertical plate directly opposite the retaining strip.

[0009] By adopting the above technical solution, the card strip and the card slot cooperate to achieve reliable positioning of two adjacent silicon steel sheets when stacked on top of each other, and avoid gaps between two adjacent silicon steel sheets.

[0010] Furthermore, the two long sidewalls of the card strip have a V-shaped structure, the top of the card strip has an arc-shaped structure, and the shape of the card slot matches the shape of the card strip.

[0011] By adopting the above technical solution, the card slot has a structure that is large at both ends and small in the middle, ensuring that the card strip can be reliably positioned after insertion.

[0012] Furthermore, both the card strip and the card slot are integrally formed with the silicon steel vertical plate.

[0013] By adopting the above technical solution, the one-piece molding connection method ensures that the magnetism of the silicon steel sheet is not affected after the card strip is assembled.

[0014] Furthermore, the assembly platform is integrally formed with the silicon steel horizontal plate, and the assembly platform has a square structure, with a thickness less than that of the silicon steel horizontal plate.

[0015] By adopting the above technical solution, the assembly platform and the assembly slot can be inserted to achieve the initial positioning of the silicon steel vertical plate and the silicon steel horizontal plate.

[0016] Furthermore, the depth of the assembly groove is less than the thickness of the silicon steel vertical plate, and the limiting insertion hole penetrates through the silicon steel vertical plate.

[0017] By adopting the above technical solution, the limiting insert and the limiting hole can be used to further limit the silicon steel vertical plate and the silicon steel horizontal plate.

[0018] Furthermore, the size of the limiting insertion hole matches the size of the limiting insertion post.

[0019] By adopting the above technical solution, it is ensured that the limiting plug can be stably fixed after being inserted into the limiting hole.

[0020] (III) Beneficial Effects

[0021] Compared with the prior art, this utility model has the following advantages:

[0022] To address the current issue of assembled silicon steel sheets for large transformers, the method involves pre-drilling a V-shaped groove on the vertical silicon steel plate and a V-shaped platform at each end of the horizontal silicon steel plate. Two vertical silicon steel plates are then placed parallel to each other on a support base, followed by three horizontal silicon steel plates placed horizontally between the two vertical plates, and finally glued together. While this method achieves the assembly of silicon steel sheets for large transformers, it suffers from a vulnerability to accidental damage during assembly because the vertical and horizontal silicon steel plates are not effectively restrained in the horizontal plane. The problem of loosening and tilting due to collisions, resulting in low assembly efficiency of silicon steel sheets for transformers, is addressed by creating assembly slots in the vertical silicon steel plates and pre-reserving limiting holes at the bottom of the slots. Furthermore, an assembly platform is pre-reserved on the horizontal silicon steel plates, with limiting posts at the bottom of the platform that mate with the limiting holes. This allows the vertical and horizontal silicon steel plates to be horizontally fixed and limited by the limiting holes and posts after assembly, preventing them from loosening due to external collisions during assembly and thus improving the assembly efficiency of silicon steel sheets for transformers.

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0030] like Figures 1-4As shown, a type of silicon steel sheet capable of limiting positioning in this embodiment includes two silicon steel vertical plates 2 arranged in parallel. Three silicon steel horizontal plates 4 are installed in parallel between the two silicon steel vertical plates 2. Each silicon steel vertical plate 2 has an assembly groove 5 at its upper end where it mates with the silicon steel horizontal plate 4. A limiting insertion hole 6 is reserved at the bottom end of the assembly groove 5. Both ends of the silicon steel horizontal plate 4 have assembly platforms 3 that mate with the assembly grooves 5 on the two silicon steel vertical plates 2. A limiting insertion post 7 is installed at the middle of the bottom end of the assembly platform 3. After the assembly platform 3 is inserted into the assembly groove 5, the silicon steel vertical plate 2 and the silicon steel horizontal plate 4 can be initially limited. After the limiting insertion post 7 mates with the limiting insertion hole 6, the silicon steel vertical plate 2 and the silicon steel horizontal plate 4 can be further limited.

[0031] like Figures 1-4 As shown in this embodiment, a retaining strip 1 is installed on the upper end of the silicon steel vertical plate 2, located on one side of the assembly groove 5. A retaining groove 8 is provided at the bottom end of the silicon steel vertical plate 2, directly opposite the retaining strip 1. The retaining strip 1 and the retaining groove 8 cooperate to reliably limit the position of two adjacent silicon steel sheets when stacked, avoiding gaps between two adjacent silicon steel sheets. The two long side walls of the retaining strip 1 have a V-shaped structure, and the top of the retaining strip 1 has an arc-shaped structure. The shape of the retaining groove 8 matches the shape of the retaining strip 1. The retaining groove 8 has a structure that is large at both ends and small in the middle, ensuring that the retaining strip 1 can be reliably limited after insertion. The retaining strip 1 and the retaining groove 8 are integrally formed with the silicon steel vertical plate 2. The integral forming connection method ensures that the magnetism of the silicon steel sheet is not affected after the retaining strip 1 is assembled.

[0032] like Figures 1-4 As shown, in this embodiment, the assembly platform 3 and the silicon steel horizontal plate 4 are integrally formed, and the assembly platform 3 has a square structure. The thickness of the assembly platform 3 is less than the thickness of the silicon steel horizontal plate 4, the depth of the assembly groove 5 is less than the thickness of the silicon steel vertical plate 2, and the limiting insertion hole 6 penetrates the silicon steel vertical plate 2. The size of the limiting insertion hole 6 matches the size of the limiting insertion post 7, ensuring that the limiting insertion post 7 can be stably fixed after being inserted into the limiting insertion hole 6.

[0033] The specific implementation process of this embodiment is as follows: During assembly, firstly, two silicon steel vertical plates 2 are placed parallel to each other on the assembly base. Then, the assembly platform 3 on the three silicon steel horizontal plates 4 is inserted into the assembly slot 5 on the silicon steel vertical plate 2, and the limiting pin 7 is inserted into the limiting hole 6. Then, simply make the silicon steel horizontal plates 4 securely engaged to achieve the assembly of the silicon steel sheets for the transformer. When stacking the upper and lower silicon steel sheets, the upper and lower silicon steel sheets can be stably fixed with the cooperation of the locking strip 1 and the locking slot 8. Due to the above assembly process, through By opening an assembly slot 5 in the silicon steel vertical plate 2 and reserving a limiting insertion hole 6 at the bottom of the assembly slot 5, and reserving an assembly platform 3 on the silicon steel horizontal plate 4 and reserving a limiting insertion post 7 at the bottom of the assembly platform 3 to cooperate with the limiting insertion hole 6, the silicon steel vertical plate 2 and silicon steel horizontal plate 4 on the transformer silicon steel sheet can be limited and fixed in the horizontal plane under the action of the limiting insertion hole 6 and the limiting insertion post 7 after assembly. This avoids the silicon steel vertical plate 2 and silicon steel horizontal plate 4 from loosening due to external collisions during the assembly process, and makes the assembly efficiency of the transformer silicon steel sheet higher.

[0034] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
