Description

Technical Field

[0001] This utility model belongs to the field of iron core manufacturing technology, specifically relating to a connection module for making irregularly shaped silicon steel sheets. Background Technology

[0002] Motor cores are typically made of multiple layers of laminated silicon steel sheets. During the manufacturing process, to ensure tight bonding between the layers, snap-fit ​​structures are often stamped onto the surface. Adjacent silicon steel sheets are interlocked through these snap-fits, achieving a tight fit. To reduce iron loss, connecting components are used to fix the silicon steel sheets during manufacturing, with the snap-fits located on these components. However, when manufacturing irregularly shaped silicon steel sheets, to ensure a strong connection between the connecting components and the sheets, the connecting components must contact at least two surfaces of the sheets. However, due to the shape and angle of some irregularly shaped silicon steel sheets, separating the connecting components after stacking multiple sheets is difficult. To facilitate the separation of the connecting components, a connecting module for manufacturing irregularly shaped silicon steel sheets is proposed. Utility Model Content

[0003] This utility model aims to solve at least one of the technical problems existing in the prior art.

[0004] Therefore, this utility model proposes a connecting module for making irregularly shaped silicon steel sheets, which has the advantage of facilitating the separation of connecting units.

[0005] According to an embodiment of the present invention, a connecting module for fabricating irregularly shaped silicon steel sheets includes: a first sheet, a second sheet, and two connecting units; the first sheet and the second sheet have the same shape and are mirror images of each other; the two connecting units are spaced apart, each connecting unit having at least one first contact surface with the first sheet and at least one second contact surface with the second sheet, the first contact surface and the second contact surface being located on opposite sides of the first sheet and the second sheet, respectively, and both the first sheet and the second sheet being located between the two connecting units; at least two rivet units are formed on each connecting unit, and the at least two rivet units are spaced apart.

[0006] According to one embodiment of the present invention, at least two of the rivet units are located at both ends of the connecting unit.

[0007] According to one embodiment of the present invention, the connecting unit includes at least two connecting pieces, which are spaced apart, and a reinforcing structure is provided between two adjacent connecting pieces, the reinforcing structure being used to connect the two adjacent connecting pieces.

[0008] According to one embodiment of the present invention, the reinforcing structure includes a first connecting part and a second connecting part. The first connecting part and the second connecting part are connected by a concave-convex interlocking manner. The connection between the first connecting part and the second connecting part has a certain rotational space so that the two adjacent connecting pieces can form a folding tendency when subjected to force.

[0009] According to one embodiment of the present invention, a protrusion is formed on the first connecting part, and a groove is formed on the second connecting part, wherein the protrusion is arc-shaped.

[0010] According to one embodiment of the present invention, the first sheet, the second sheet, and the connecting unit have the same thickness, and the lower surfaces of the first sheet, the second sheet, and the connecting unit are all located on the same plane.

[0011] According to one embodiment of the present invention, the first contact surface and the second contact surface are arranged opposite to each other.

[0012] According to one embodiment of the present invention, the rivet unit includes a plurality of rivet points, which are spaced apart.

[0013] According to one embodiment of the present invention, the first sheet and the second sheet are arranged at intervals.

[0014] The beneficial effects of this utility model are that by mirroring the first and second pieces, the connecting unit contacts the first and second pieces at the first and second contact surfaces. This avoids the phenomenon where, when only the first piece is connected, the other end is misaligned due to its own weight, thus ensuring the stability of the connecting unit. Furthermore, it allows for smooth detachment of the connecting unit by selecting only one side of the first piece for easy detachment, reducing the limitations on the shape of the first and second pieces. In addition, the simultaneous stacking of the first and second pieces improves work efficiency.

[0015] Other features and advantages of this invention will be set forth in the description which follows, and will be apparent in part from the description, or may be learned by practicing the invention.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] The following describes in detail, with reference to the accompanying drawings, the irregular silicon steel sheet fabrication and connection module of this utility model embodiment.

[0027] like Figures 1-3 As shown, the irregularly shaped silicon steel sheet connecting module according to an embodiment of the present invention includes: a first sheet 1, a second sheet 2, and two connecting units; the first sheet 1 and the second sheet 2 have the same shape and are mirror images of each other; the two connecting units are spaced apart, and each connecting unit has at least one first contact surface 3 with the first sheet 1 and at least one second contact surface 4 with the second sheet 2, the first contact surface 3 and the second contact surface 4 are respectively located on opposite sides of the first sheet 1 and the second sheet 2, and both the first sheet 1 and the second sheet 2 are located between the two connecting units; at least two rivet units 5 are formed on the connecting unit, and the at least two rivet units 5 are spaced apart.

[0028] In this embodiment, when arranging the first piece 1 and the second piece 2, the sides of the first piece 1 and the second piece 2 that are at least partially flat or that gradually taper inward from the center of the side are set as the opposite sides of the first piece 1 and the second piece 2. This ensures the area of ​​the first contact surface 3 and the second contact surface 4, guarantees the connection strength between the connecting unit and the first piece 1 and the second piece 2, and facilitates the subsequent separation of the connecting unit from the first piece 1 and the second piece 2 along both sides of the side. By mirroring the first piece 1 and the second piece 2, the connecting unit contacts the first piece 1 and the second piece 2 at the first contact surface 3 and the second contact surface 4. This avoids the phenomenon that when it is only connected to the first piece 1, the other end is misaligned with the first piece 1 due to its own weight. This ensures the stability of the connecting unit and allows the connecting unit to be smoothly detached by selecting only one side on the first piece 1 that is easy to detach. This reduces the limitations on the shape of the first piece 1 and the second piece 2. In addition, the stacking of the first piece 1 and the second piece 2 is completed simultaneously, improving work efficiency.

[0029] At least two rivet units 5 are located at both ends of the connecting unit. The use of two rivet units 5 ensures the fit between the first piece 1 and the first piece 1, and avoids the phenomenon of lifting edges.

[0030] The connecting unit includes at least two connecting pieces 6, which are spaced apart. A reinforcing structure 7 is provided between two adjacent connecting pieces 6, and the reinforcing structure 7 is used to connect the two adjacent connecting pieces 6.

[0031] The reinforcing structure 7 includes a first connecting part 71 and a second connecting part 72. The first connecting part 71 and the second connecting part 72 are connected by a concave-convex interlocking manner. The connection between the first connecting part 71 and the second connecting part 72 has a certain rotation space so that the two adjacent connecting pieces 6 can form a folding tendency when subjected to force.

[0032] In this embodiment, preferably, there are two connecting pieces 6, with at least two rivet units 5 evenly distributed on the two connecting pieces 6 to ensure the fit between the first piece 1 and the second piece 2. The connection of the two connecting pieces 6 is achieved through the reinforcing structure 7. At the same time, when the connecting unit is separated by force, the two connecting pieces 6 deform at the reinforcing structure 7, causing the two connecting pieces 6 to rotate at a certain angle with a gradual folding tendency, so that the connecting pieces 6 gradually separate from the first piece 1 and the second piece 2. This reduces the limitation that the first contact surface 3 and the second contact surface 4 must both be planar, increases the contact area between the connecting piece 6 and the first piece 1 and the second piece 2, and increases the applicability.

[0033] A protrusion is formed on the first connecting part 71, and a groove is formed on the second connecting part 72. The protrusion is arc-shaped.

[0034] The first piece 1, the second piece 2, and the connecting unit have the same thickness, and the lower surfaces of the first piece 1, the second piece 2, and the connecting unit are all located on the same plane. That is to say, the lower surfaces of the first piece 1, the second piece 2, and the connecting unit are flush, and the upper surfaces of the first piece 1, the second piece 2, and the connecting unit are also flush, so that when adjacent connecting units are fastened together, the first piece 1 and the second piece 2 are tightly fitted together.

[0035] The first contact surface 3 and the second contact surface 4 are arranged opposite to each other. By arranging them opposite to each other, the connecting unit has a certain holding force on the first piece 1 and the second piece 2, so as to maintain the stability of the connection between the connecting unit and the first piece 1 and the second piece 2.

[0036] The rivet unit 5 includes multiple rivet points, which are spaced apart.

[0037] The first piece 1 and the second piece 2 are spaced apart. By spaced them apart, a positioning structure can be added between them to ensure the stability of the first piece 1 and the second piece 2 when the connecting unit is separated. At the same time, only one positioning structure is needed, which reduces the operation steps and improves work efficiency.

[0038] The outer contour of the connecting unit includes, but is not limited to, circles, squares, polygons, irregular shapes, etc., and can be designed according to the stacking requirements or the shape of the material strip for stamping the first sheet 1 and the second sheet 2.

[0039] In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "illustrative embodiment," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of the present invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0040] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
