[0002] Silicon steel sheets, also known as electrical steel sheets, are a kind of silicon-iron soft magnetic alloy with extremely low carbon content, mainly used in power frequency alternating current electromagnetic devices, such as the iron cores of transformers, motors, current transformers, switches, and relays.

[0003] For the existing silicon steel sheets, their surfaces are smooth, resulting in relative sliding between the silicon steel sheets when stacked together. To avoid this situation, a silicon steel sheet for laminated assembly that is convenient for plugging is provided. Content of the Utility Model

[0004] The purpose of the utility model is to provide a silicon steel sheet for laminated assembly that is convenient for plugging to solve the problems in the above background.

The docking groove and the straight groove opening are symmetrically distributed with the midline of the E-shaped silicon steel sheet as the center. Two folding edge notch grooves are symmetrically opened at one end edge of the E-shaped silicon steel sheet with the docking groove as the center. The E-shaped silicon steel sheet forms a rectangular folding edge through the docking groove and the folding edge notch groove. The rectangular folding edge is bent downward and distributed at a right angle to the E-shaped silicon steel sheet;

[0006] At the position where one end edge of the E-shaped silicon steel sheet is aligned with the straight groove opening, a concave notch groove is opened in the straight groove opening. The E-shaped silicon steel sheet forms a convex folding edge through the straight groove opening and the concave notch groove. The convex folding edge is bent upward and distributed at a right angle to the E-shaped silicon steel sheet;

[0007] The upper and lower adjacent E-shaped silicon steel sheets are distributed with a 180-degree flip. The convex folding edge on one E-shaped silicon steel sheet is aligned with the docking groove on the other E-shaped silicon steel sheet and is snapped in. The rectangular folding edge on one E-shaped silicon steel sheet is snapped into the concave notch groove on the other E-shaped silicon steel sheet and is attached to the convex folding edge to realize the horizontal limit of the two E-shaped silicon steel sheets.

[0008] As a further scheme of the utility model: The height of the rectangular folding edge and the convex folding edge protruding from the E-shaped silicon steel sheet matches the thickness of the E-shaped silicon steel sheet. The upper and lower end side surfaces of the rectangular folding edge and the convex folding edge are in an arc surface structure.

[0009] As a further solution of the present utility model: The length of the inner wall of the docking groove matches the length of the small-sized part of the convex folded edge, and the length of the inner wall of the docking groove is less than the length of the inner wall of the rectangular folded edge.

When the convex folded edge is clamped inside the docking groove and fits with the rectangular folded edge, the clamping convex point is clamped inside the clamping hole to realize the vertical preliminary limit of two E-shaped silicon steel sheets.

[0011] As a further solution of the present utility model: Two groups of symmetrically distributed clamping convex points are formed on the upper and lower parts of a single convex folded edge, and the centers of the clamping hole and the upper clamping convex point are flush with the horizontal central plane of the E-shaped silicon steel sheet.

[0012] As a further solution of the present utility model: The E-shaped silicon steel sheet, the docking groove, the folded edge notch groove, the clamping hole, the straight notch, and the concave notch groove are formed by punching process, the clamping convex point is formed by stamping process, and the rectangular folded edge and the convex folded edge are formed by bending process.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] By setting the docking groove, the rectangular folded edge, the concave notch groove, and the convex folded edge, when two adjacent E-shaped silicon steel sheets are spliced, only need to keep the state of flipping 180 degrees relative to each other for splicing. Through the clamping of the rectangular folded edge and the concave notch groove and the clamping of the convex folded edge and the docking groove, the horizontal limit of two E-shaped silicon steel sheets can be realized. In addition, through the mutual clamping of the clamping convex point and the clamping hole, the vertical limit of multiple E-shaped silicon steel sheets can be realized, so that the splicing of multiple E-shaped silicon steel sheets is kept in a stable state, and the phenomenon of deviation can be effectively avoided.

[0025] In this embodiment: When splicing multiple E-shaped silicon steel sheets 1, the operation steps are as follows:

[0026] Make the rectangular flange 4 and the convex flange 8 on the first E-shaped silicon steel sheet 1 face downward. Then, flip the second E-shaped silicon steel sheet 1 180 degrees relative to the first E-shaped silicon steel sheet 1, so that the rectangular flange 4 on the second E-shaped silicon steel sheet 1 faces upward and the convex flange 8 faces downward, and the convex flange 8 on the second E-shaped silicon steel sheet 1 is aligned with the docking groove 2 on the first E-shaped silicon steel sheet 1, while the convex flange 8 on the first E-shaped silicon steel sheet 1 is aligned with the docking groove 2 on the second E-shaped silicon steel sheet 1;
