Description

Technical Field

[0001] This utility model relates to the field of transformer core pressing technology, specifically a transformer core pressing device. Background Technology

[0002] Core lamination refers to the process of combining multiple silicon steel sheets to form a core. Common methods for laminating silicon steel sheets in transformer cores include sliding lamination, planar cross lamination, and oblique lamination. According to application number CN221149801U, a transformer core pressing device, through the coordinated arrangement of positioning components, fixing components, and pressing components, achieves the effect of aligning silicon steel sheets from both sides, pressing and fixing the silicon steel sheets from top to bottom, and pressing the overlapping silicon steel sheets from the other two sides. This ensures that each overlapping silicon steel sheet is pressed and fixed in all directions, and during the pressing and fixing process, it is pressed and shaped into a transformer core, preventing the silicon steel sheets from shifting and achieving a tighter core. However, this device can only press a core of one size; it cannot meet the need to press cores of multiple sizes. Utility Model Content

[0011] 1. This transformer core pressing device, equipped with a second telescopic plate, a first telescopic plate, and a top plate, allows the user to fix the position of the first telescopic plate and the top plate by unscrewing one end of the first screw out of the first positioning hole, then pulling the top plate and the first telescopic plate out of the bottom box, and screwing one end of the first screw into the corresponding first positioning hole. Then, the operator unscrews one end of the second screw out of the second positioning hole, pulls the side plate and the second telescopic plate out of the side box, adjusts the position of the side plate and the second telescopic plate, and then screws one end of the second screw into the corresponding second positioning hole to limit and fix the position of the second telescopic plate and the side plate.

[0025] A first scale plate 10 is fixedly connected to one side of the first telescopic plate 6. One end of the first scale plate 10 extends to the top of the bottom box 5. A second scale plate 16 is fixedly connected to one end of the second telescopic plate 12. One end of the second scale plate 16 extends to the outside of the side box 11. By checking the scale of the second scale plate 16, it is convenient to adjust the extension length of the side plate 15. By checking the scale of the first scale plate 10, it is convenient to adjust the extension length of the top plate 9.

[0026] Both ends of the top of the base plate 1 are fixedly connected to the upright plate 17, and one side of the upright plate 17 is fixedly connected to the first electric telescopic rod 18. The telescopic end of the first electric telescopic rod 18 is fixedly connected to the first pressure plate 19, and the first pressure plate 19 can be moved by the telescopic end of the first electric telescopic rod 18.

[0027] Guide rails 20 are fixedly connected to the top of the base plate 1 and to the front and rear of the base box 5. Threaded rods 22 are rotatably connected inside each guide rail 20. A self-locking motor 21 is fixedly connected to one side of each guide rail 20. The output end of the self-locking motor 21 is fixedly connected to one end of the threaded rod 22.

[0029] Example 2

[0030] Please see Figure 1 The present invention provides a technical solution: a top frame 2 is fixedly connected to the top of the base plate 1, a hydraulic rod 3 is fixedly connected to the top of the top frame 2, the telescopic end of the hydraulic rod 3 extends to the bottom of the top frame 2 and is fixedly connected to a pressing block 4, and the pressing block 4 is moved by pushing the telescopic end of the hydraulic rod 3 to press the stacked silicon steel sheets into an iron core.

[0031] In summary, during use, the transformer core pressing device involves placing stacked silicon steel sheets on the top plate 9 and side plate 15. Then, an external controller controls the extension end of the second electric telescopic rod 25 to move the second pressure plate 26, and the extension end of the first electric telescopic rod 18 to move the first pressure plate 19. The first pressure plate 19 and the second pressure plate 26 limit the outer sides of the stacked silicon steel sheets. Then, the extension end of the hydraulic rod 3 pushes the pressing block 4 downwards, pressing the stacked silicon steel sheets together to form the core. Then, the extension end of the hydraulic rod 3 moves the pressing block 4 upwards, and the extension end of the second electric telescopic rod 25... The retracting end drives the second pressure plate 26 to reset and move, and the telescopic end of the first electric telescopic rod 18 drives the first pressure plate 19 to reset and move, releasing the limit on the iron core. Then, the pressed iron core is removed from the top plate 9 and the side plate 15, and then the transformer iron core pressing work continues. When it is necessary to press iron cores of various sizes, the output end of the self-locking motor 21 drives the threaded rod 22 to rotate, so that the threaded rod 22 drives the moving block 23 to move the mounting base 24, the second electric telescopic rod 25 and the second pressure plate 26 to one side of a side box 11.

Adjust the extension length of the first telescopic plate 6 and the position of the top plate 9 by checking the scale on the extended first scale plate 10. After adjusting the positions of the first telescopic plate 6 and the top plate 9 to a suitable position, screw one end of the first screw 7 into the corresponding first positioning hole 8 to fix the positions of the first telescopic plate 6 and the top plate 9. Then, the operator screws one end of the second screw 13 out of the second positioning hole 14. Next, pull the side plate 15 and the second telescopic plate 12 out from inside the side box 11, adjust the positions of the side plate 15 and the second telescopic plate 12, and then... The scale on the second scale plate 16, which is moved out by the telescopic plate 12, can be used to determine the moving length of the second telescopic plate 12 and the side plate 15. This allows the second telescopic plate 12 and the side plate 15 to be adjusted to the required extension length. Then, one end of the second screw 13 is screwed into the corresponding second positioning hole 14 to limit and fix the position of the second telescopic plate 12 and the side plate 15. Then, the output end of the self-locking motor 21 drives the threaded rod 22 to reset and rotate, so that the threaded rod 22 drives the moving block 23 to move the mounting base 24, the second electric telescopic rod 25 and the second pressure plate 26 to the working position to continue the transformer core pressing work.
