Description

Technical Field

[0001] The utility model belongs to the technical field of silicon steel sheets, in particular to a 45-degree oblique shear silicon steel sheet. Background Art

[0002] In some larger transformer cores, silicon steel sheets are usually made by welding multiple sheets, and each individual sheet is usually cut at a 45-degree angle to facilitate 90-degree welding. A common problem in current technology is that the two sheets to be welded are aligned at two 45-degree edges and welded. During the alignment process, it is usually done manually or by equipment. Whether it is manual alignment or equipment, there are usually accuracy problems. As the number of silicon steel sheets is added, it will eventually cause certain defects in the appearance of the core, thereby affecting the magnetic conduction process. Utility Model Content

[0024] 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.

[0025] 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.

[0026] 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.

[0027] 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.

[0028] Example 1

[0029] Reference Figure 1 and Figure 2 , is the first embodiment of the utility model, which provides a 45-degree oblique sheared silicon steel sheet. In the utility model, the two 45-degree oblique sheared silicon steel sheets to be aligned and welded are referred to as the first sheet body and the second sheet body, wherein the 45-degree inclined edges of the two sheets also have the following structural features:

[0030] The two 45-degree inclined edges of the two sheets are respectively provided with a convex portion 100 and a concave portion 200. The convex portion 100 is structurally beyond the 45-degree inclined edge, and the concave portion 200 is recessed toward the inner side of the 45-degree inclined edge. The outer dimension of the convex portion 100 is consistent with the inner dimension of the concave portion 200.

[0031] When the convex portion 100 is located in the concave portion 200, the two 45-degree inclined edges are flush with each other, and the first sheet body and the second sheet body remain coplanar, thereby achieving an alignment effect;

[0032] Based on the above, in the utility model, the convex portion 100 can be arranged in a circular shape, and the concave portion 200 can be arranged in a concave arc shape. While keeping the first sheet body aligned with the second sheet body, the convex portion 100 can be directly arranged in the concave portion 200. This process can be operated manually or by equipment. Compared with the two sheet body structure in the prior art, the utility model can quickly realize the precise alignment of the two sheets, thereby facilitating the subsequent welding process, and can correspondingly increase the welding speed.

[0033] Furthermore, the number of combinations of the protrusions 100 and recesses 200 can be one or more. When there are more than one, the protrusions 100 and recesses 200 are distributed in sequence along the 45-degree inclined edge. The multiple settings enable the two sheets to achieve a riveting effect, thereby improving the strength after welding.

[0034] Further, see Figure 1-5 The height of the protrusion 100 can be kept consistent with the thickness of the two sheets, and the recess 200 runs through the thickness direction of the two sheets. This structure makes the two sheets more secure when riveted. In addition, the height of the protrusion 100 can also be less than the thickness of the two sheets. At this time, the depth of the recess 200 is consistent with the thickness of the protrusion 100. Specifically, the height of the protrusion 100 is most appropriately half the thickness of the two sheets. This structure can further simplify the difficulty of alignment, thereby increasing the alignment speed.

[0035] Example 2

[0036] Reference Figure 3-5 This is the second embodiment of the utility model. In this embodiment, the convex portion 100 can adopt a square structure, and the concave portion 200 corresponds to a square groove structure. This structure makes it easier to cut the sheet in the initial state, has lower requirements on equipment, and is easy to manufacture.

[0037] Further, see Figure 3 and Figure 5 The widths of the protrusions 100 and the recesses 200 are linearly extended along the width direction of the square structure, and the extension direction is consistent with the length direction of the 45-degree inclined edge, so that the alignment area between the two sheets can be increased when aligning, thereby facilitating the alignment process and simplifying the operation. At the same time, there is no need to set up multiple sets of protrusions 100 and recesses 200, making the manufacturing process simpler.

[0038] 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.

[0039] 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.
