Description

Technical Field

[0001] The utility model belongs to the technical field of silicon steel sheets, in particular to an E-type silicon steel sheet. Background Art

[0002] E-type silicon steel sheets are an important component of the transformer core. At present, in the stacking and assembly process of E-type silicon steel sheets, the single sheets are cut out and then stacked and pressed by equipment. In this process, the single sheets need to be clamped by corresponding clamping mechanisms so as to be placed on the equipment. Since the silicon steel sheets are in sheet shape and thin in size, they are usually difficult to be clamped when placed flat. In the stacking process, the single sheets need to be aligned to ensure neat placement. Due to the limitation of the size of the single sheets and the overly flat surface, when stacking, the clamping mechanism is difficult to find the specific unloading position and direction during the unloading process, which makes the entire processing process more difficult.

[0018] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0019] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0020] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0021] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0022] Example 1

[0023] Reference Figure 1 and Figure 2 , is the first embodiment of the utility model, which provides an E-type silicon steel sheet, including a silicon steel sheet body, hereinafter referred to as a sheet body, wherein:

[0024] The sheet body has a first side 100 and a second side 200. When the sheets are stacked and assembled, the adjacent first sides 100 and second sides 200 are kept in contact with each other. The first side 100 is provided with a raised portion 101, and the second side 200 is provided with a recessed portion 201, which are located at the same position on the surface of the sheet body.

[0025] The protrusion 101 and the recess 201 are both arc-shaped structures. When a plurality of the sheets are overlapped, the corresponding first side 100 and second side 200 are attached together, so that the protrusion 101 is filled in the recess 201.

[0026] Based on the above, when the sheets are overlapped, the raised portion 101 is located in the recessed portion 201 to achieve the effect of aligning the sheets, thereby facilitating placement during stacking. The structure of the raised portion 101 makes the thickness of this position on the sheet greater than the thickness of other areas. Therefore, when clamped in cooperation with the clamping mechanism, the clamping mechanism can clamp at the position of the raised portion 101, which is more likely to be clamped than other areas, thereby effectively reducing the difficulty of the entire assembly. When the sheets are overlapped and pressed, since the other side of the raised portion 101 is the recessed portion 201, the raised portion 101 and the recess can be directly pressed off and disappear, so that the first side 100 and the second side 200 of the entire sheet form a complete plane, thereby leaving no processing marks.

[0027] Further, see Figure 2 There is a first spacing 300 and two second spacings 400 between the raised portion 101 and the recessed portion 201. The two second spacings 400 are located at the two ends of the arc structure of the raised portion 101. The first spacing 300 is located at the top of the raised portion 101. The first spacing 300 is slightly larger than the second spacing 400. The second spacing 400 is consistent with the thickness of the main area of ​​the sheet. When the raised portion 101 and the recessed portion 201 are flattened, the recessed portion 201 is an arc-shaped structure. During the flattening process, the middle part will be subjected to a pulling force toward both ends. By thickening at the first position, the anti-pulling effect can be fully achieved, and the increased thickness is supplemented to the middle part of the recessed portion 201 to prevent breakage, thereby improving the processing quality.

[0028] Further, see Figure 2 The arc angles of the raised portion 101 and the recessed portion 201 are both between 50 and 60 degrees. When the arc angles of the raised portion 101 and the recessed portion 201 are greater than 60 degrees, the highest point of the first side 100 will be too high, which will increase the difficulty of pressing. When the angle is lower than 50 degrees, the bulge of the raised portion 101 will not be significant enough, which is not conducive to clamping. Therefore, it is best to control the angle between 50 and 60 degrees.

[0029] Further, see Figure 1 The sheet body has a calibration direction parallel to itself, and the calibration direction is consistent with the coil axis direction, that is, when the coil is wound, the coil axis remains parallel to the calibration direction, and the arc axis of the raised portion 101 and the recessed portion 201 are parallel to the calibration direction. At this time, the arc axis direction is consistent with the "E"-shaped letter opening direction of the sheet body. At this time, the specific positions of the raised portion 101 and the recessed portion 201 are as shown in the figure, thereby reducing the size of the raised portion 101 and the recessed portion 201.

[0030] Example 2

[0031] Reference Figure 3 , which is the second embodiment of the utility model. Different from Embodiment 1, this embodiment provides another setting position and direction for the raised portion 101 and the recessed portion 201. Specifically, the arc axes of the raised portion 101 and the recessed portion 201 are perpendicular to the calibration direction. The positions of the raised portion 101 and the recessed portion 201 are as shown in the figure, and they can be located in the middle of the "E"-shaped letter opening of the sheet body, so that when clamping the sheet body, it can be clamped in the middle of the sheet body to improve the clamping stability.

[0032] It will be appreciated that in the development of any actual implementation, as in any engineering or design project, numerous implementation-specific decisions may be made. Such a development effort may be complex and time-consuming, but will be a routine task of design, fabrication, and production for those of ordinary skill having the benefit of this disclosure without undue experimentation.

[0033] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
