Description

Technical Field

[0001] The utility model relates to the field of E-shaped silicon steel sheets of transformers, in particular to a transformer core facilitating the assembly of silicon steel sheets. Background Technique

[0002] Silicon steel is a kind of steel containing silicon (silicon is also called silicon), and its silicon content is 0.8 - 4.8%. Using silicon steel as the iron core of a transformer is because silicon steel itself is a magnetic substance with very strong magnetic conductivity. In an energized coil, it can generate a relatively large magnetic induction intensity, thus enabling the volume of the transformer to be reduced.

[0003] In the prior art, after E-shaped silicon steel sheets are stacked, installation columns are required to fix the stacked silicon steel sheets. However, during the stacking process, due to the misalignment and offset of the silicon steel sheets in the vertical position, the installation columns cannot be effectively and quickly inserted, and continuous correction is needed, making the installation process rather laborious. Content of the Utility Model

[0005] To achieve the above purpose, the utility model provides the following technical solution: A transformer core facilitating the assembly of silicon steel sheets, including a bottom silicon steel sheet, with a plurality of intermediate silicon steel sheets stacked on the top end of the bottom silicon steel sheet, and a top silicon steel sheet stacked on the top of the intermediate silicon steel sheet at the uppermost position. A docking mechanism is arranged on the flat parts of the top silicon steel sheet, intermediate silicon steel sheets, and bottom silicon steel sheet. The docking mechanism is used to achieve the precise stacking of the top silicon steel sheet, intermediate silicon steel sheets, and bottom silicon steel sheet, avoiding misalignment.

[0006] The docking mechanism includes a trapezoidal groove integrally formed at the center of the flat ends of the top silicon steel sheet, intermediate silicon steel sheets, and bottom silicon steel sheet. A top docking convex block is integrally formed below the trapezoidal groove at the bottom end of the top silicon steel sheet.

[0007] As a further scheme of the utility model: The docking mechanism includes an intermediate receiving groove integrally formed at the top of the intermediate silicon steel sheet and recessed downward.

[0008] As a further scheme of the utility model: The docking mechanism further includes an intermediate docking convex block integrally formed at the bottom end of the intermediate silicon steel sheet. The inner wall of the intermediate receiving groove fits the outer wall of the intermediate docking convex block. Two adjacent intermediate silicon steel sheets up and down are engaged through the intermediate receiving groove and the intermediate docking convex block.

[0009] As a further solution of the present utility model: a downwardly concave bottom receiving groove is integrally formed at the top of the bottom silicon steel sheet, and the bottom receiving groove is used to receive the intermediate docking protrusion at the bottom of the lowermost intermediate silicon steel sheet.

[0010] As a further solution of the present utility model: docking holes are provided at two right-angled corners of the top silicon steel sheet, the intermediate silicon steel sheet and the bottom silicon steel sheet, and the stacked top silicon steel sheet, bottom silicon steel sheet and multiple intermediate silicon steel sheets are installed and fixed by passing mounting posts through the docking holes.

[0018] Please refer to Figures 1 to 3, in the embodiment of the present utility model, a transformer core facilitating the assembly of silicon steel sheets includes a bottom silicon steel sheet 3. A plurality of intermediate silicon steel sheets 2 are stacked on the top end of the bottom silicon steel sheet 3. A top silicon steel sheet 1 is stacked on the top of the intermediate silicon steel sheet 2 at the uppermost position. A docking mechanism is provided on the flat portions of the top silicon steel sheet 1, the intermediate silicon steel sheets 2, and the bottom silicon steel sheet 3. The docking mechanism is used to achieve the precise stacking of the top silicon steel sheet 1, the intermediate silicon steel sheets 2, and the bottom silicon steel sheet 3, avoiding misalignment situations.

[0019] In this embodiment: When docking the silicon steel sheets, first place the bottom silicon steel sheet 3 at the lowest end. Then, stack an intermediate silicon steel sheet 2 on the top of the top silicon steel sheet 1 first. After completion, stack a plurality of intermediate silicon steel sheets 2 on the lowermost intermediate silicon steel sheet 2 in sequence. After stacking the plurality of intermediate silicon steel sheets 2, stack the top silicon steel sheet 1 above the uppermost intermediate silicon steel sheet 2. During the stacking process of the top silicon steel sheet 1, the intermediate silicon steel sheets 2, and the bottom silicon steel sheet 3, the top silicon steel sheet 1, the intermediate silicon steel sheets 2, and the bottom silicon steel sheet 3 are precisely docked through the docking mechanism, avoiding misalignment and offset during the stacking process of the top silicon steel sheet 1, the intermediate silicon steel sheets 2, and the bottom silicon steel sheet 3.

[0020] Please refer specifically to Figure 1 , Figure 2 and Figure 3 , the docking mechanism includes a trapezoidal groove 5 integrally formed at the center of the flat ends of the top silicon steel sheet 1, the intermediate silicon steel sheets 2, and the bottom silicon steel sheet 3. A top docking protrusion 6 is integrally formed below the bottom end of the top silicon steel sheet 1 and located below the trapezoidal groove 5. The docking mechanism includes an intermediate receiving groove 7 integrally formed at the top of the intermediate silicon steel sheet 2 and recessed downward. The intermediate receiving groove 7 is used to receive the top docking protrusion 6, and the inner wall of the intermediate receiving groove 7 coincides with the outer wall of the top docking protrusion 6. The docking mechanism further includes an intermediate docking protrusion 8 integrally formed at the bottom end of the intermediate silicon steel sheet 2. The inner wall of the intermediate receiving groove 7 coincides with the outer wall of the intermediate docking protrusion 8. Two adjacent intermediate silicon steel sheets 2 up and down are engaged through the intermediate receiving groove 7 and the intermediate docking protrusion 8. A bottom receiving groove 9 is integrally formed at the top of the bottom silicon steel sheet 3 and recessed downward. The bottom receiving groove 9 is used to receive the intermediate docking protrusion 8 at the bottom of the lowermost intermediate silicon steel sheet 2.

[0021] In this embodiment: During the docking process between the middle silicon steel sheet 2 at the bottom and the bottom silicon steel sheet 3, the middle silicon steel sheet 2 at the bottom drives the middle docking bump 8 at its bottom to dock with the bottom receiving groove 9. During the docking process of multiple middle silicon steel sheets 2, the upper middle docking bump 8 docks with the lower middle receiving groove 7 until multiple middle silicon steel sheets 2 are docked in sequence. Finally, when the top silicon steel sheet 1 is stacked on the topmost middle silicon steel sheet 2, the top silicon steel sheet 1 drives the top docking bump 6 at its bottom end to the inner wall of the middle receiving groove 7 of the topmost middle silicon steel sheet 2;

[0022] During the above process, the docking mechanism realizes the precise docking of the top silicon steel sheet 1, the middle silicon steel sheet 2, and the bottom silicon steel sheet 3, avoiding the situation of dislocation during the docking process of the top silicon steel sheet 1, the middle silicon steel sheet 2, and the bottom silicon steel sheet 3.

[0023] Please refer specifically to Figure 1 , docking holes 4 are provided at the two right-angle corners of the top silicon steel sheet 1, the middle silicon steel sheet 2, and the bottom silicon steel sheet 3. The stacked top silicon steel sheet 1, bottom silicon steel sheet 3, and multiple middle silicon steel sheets 2 are installed and fixed by passing the installation posts through the docking holes 4.

[0024] In this embodiment: After the top silicon steel sheet 1, the middle silicon steel sheet 2, and the bottom silicon steel sheet 3 are stacked from bottom to top, an installation post with a diameter equal to that of the docking hole 4 is passed through. Due to the positioning of the docking mechanism, the docking holes 4 on the top silicon steel sheet 1, the middle silicon steel sheet 2, and the bottom silicon steel sheet 3 are aligned in the vertical direction, facilitating the insertion of the installation post. Since the outer wall of the installation post has threads at the top and bottom ends, after passing through, nuts can be tightened on the threaded outer wall. After tightening, the two nuts effectively compress the top silicon steel sheet 1, the middle silicon steel sheet 2, and the bottom silicon steel sheet 3.
