Description

An insulating paper flanging device for a stator slot insulating machine Technical Field

[0001] This utility model relates to the technical field of flanging devices, and in particular to a flanging device for insulating paper of a stator slot insulation machine. Background Technology

[0002] Grooved insulating paper is a solid insulating material used to isolate different conductors in electrical equipment such as motors and transformers. Currently, during the processing of grooved insulating paper, it is necessary to perform edge-flipping.

[0003] The existing flanging device consists of a base plate, a limiting strip, a guide block, a forming block, and a guide strip. The forming block is machined with an inclined semi-circular turning groove and a gap groove, and the guide strip is machined with an inclined guide surface. The insulating paper moves along the base plate and the limiting strip toward the forming block. After the corner of the insulating paper in the direction of movement contacts the guide surface, it bends at a certain angle in the guide groove formed by the guide surface of the guide strip and the surface of the guide block due to the obstruction of the guide surface. The bent insulating paper continues to move forward. After reaching the turning groove of the forming block, the bent part turns toward the insulating paper body and gradually approaches the insulating paper body. The turned grooved insulating paper continues to move forward. Through the flanging gap formed by the gap groove of the base plate and the forming block, the turned part of the grooved insulating paper is pressed tightly against the paper body, thus producing a flanging.

[0004] However, the aforementioned flanging device has a complex structure and high cost. The flanging part of the insulating paper is obscured by the guide block and forming block, making it impossible to directly observe the flanging situation and inconvenient for debugging. The bending and flipping of the slot insulating paper are completed by sliding friction, resulting in significant paper wear and affecting insulation performance. Therefore, we propose an insulating paper flanging device for a stator slot insulating machine. Summary of the Invention

[0005] The purpose of this utility model is to provide an insulating paper flanging device for a stator slot insulating machine. By setting this flanging device, the first rotating shaft and the limiting ring are used for guidance, and then the second rotating shaft and the guide ring are used for easy folding. Finally, the paper is pressed tightly by a round bar. The overall structure is simple and the cost is low. At the same time, it can reduce the wear on the slot insulating paper and make it easier to observe the processing.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an insulating paper flanging device for a stator slot insulating machine, comprising:

[0007] Support assembly;

[0008] The first rotating shaft and the second rotating shaft are respectively rotatably mounted on the bracket assembly;

[0009] Limiting rings are fixedly connected to both ends of the first rotating shaft;

[0010] Guide rings are fixedly connected to both ends of the second rotating shaft, and grooved insulating paper is inserted between the first rotating shaft and the second rotating shaft. The guide rings are used to drive the two sides of the grooved insulating paper to fold up and flip up.

[0011] Multiple round bars are located on one side of the second rotating shaft, and the multiple round bars are used to extrude groove insulating paper.

[0012] Preferably, the support assembly includes:

[0013] Back panel;

[0014] Top plate, which is fixedly connected to one side of the top of the back plate;

[0015] The base plate is fixedly connected to one side of the bottom of the back plate.

[0016] Preferably, both the first and second rotating shafts are rotatably mounted between the top and bottom plates via bearings, and the second rotating shaft is located between the round bar and the first rotating shaft.

[0017] Preferably, the side of the two limiting rings that are close to each other is set as the limiting bottom surface, and the side of the two guide rings that are close to each other is set as the guide bottom surface, and each guide bottom surface has an inclined surface on one side.

[0018] Preferably, the height difference between the two limiting bottom surfaces is the same as the width of the slot insulating paper, and the height difference between the limiting bottom surface and the corresponding guide bottom surface is the height of the folded edge of the slot insulating paper.

[0019] Preferably, both the outer surfaces of the top plate and the bottom plate have two slots, and the number of round bars is at least two. The end of each round bar is fixedly connected to the slot on the top plate and the slot on the bottom plate, respectively. The distance between the two round bars is the thickness of two layers of slotted insulating paper.

[0020] The technical effects and advantages of this utility model are as follows:

[0021] By sequentially passing the slotted insulating paper between the first and second rotating shafts, and then through multiple round bars, the slotted insulating paper is positioned by a limiting ring, allowing it to move stably along the first rotating shaft. A guide ring then folds up both sides of the slotted insulating paper, and finally, multiple round bars press the folded and flanged areas, ensuring they are tightly pressed against the slotted insulating paper. This achieves the flanging process of the slotted insulating paper. The overall design is simple, low-cost, and allows for direct observation of the flanging process, facilitating adjustments. Furthermore, the rolling friction minimizes frictional loss on the slotted insulating paper, reducing its impact on insulation performance. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] This utility model provides an insulating paper flanging device for a stator slot insulating machine, as shown in Figures 1-3, including a support assembly; a first rotating shaft 1 and a second rotating shaft 4, which are respectively rotatably mounted on the support assembly; a limiting ring 2, which is fixedly connected to both ends of the first rotating shaft 1; a guide ring 5, which is fixedly connected to both ends of the second rotating shaft 4, and slot insulating paper 10 is inserted between the first rotating shaft 1 and the second rotating shaft 4, the guide ring 5 being used to drive the slot insulating paper 10 to fold up and flanged on both sides; and multiple round rods 9, which are located on one side of the second rotating shaft 4 and are used to compress the slot insulating paper 10; by sequentially passing the slot insulating paper 10 through the first rotating shaft... Between the first rotating shaft 1 and the second rotating shaft 4, the grooved insulating paper 10 is passed through multiple round bars 9. The grooved insulating paper 10 is limited by the limiting ring 2, so that the grooved insulating paper 10 moves stably along the first rotating shaft 1. Then, the guide ring 5 is used to fold up and flip the two sides of the grooved insulating paper 10. Finally, the multiple round bars 9 are used to squeeze the folded and flipped parts, so that the folded and flipped parts are in close contact with the grooved insulating paper 10, thereby realizing the flipping process of the grooved insulating paper 10. This design has a simple overall structure, low cost, and is easy to directly observe the flipping process of the grooved insulating paper 10, which facilitates debugging. At the same time, the rolling friction has a small frictional loss on the grooved insulating paper 10, reducing the impact on its insulation performance.

[0028] It should be further explained that the bracket assembly includes: a back plate 8; a top plate 6, which is fixedly connected to one side of the top of the back plate 8; and a bottom plate 7, which is fixedly connected to one side of the bottom of the back plate 8. By setting the top plate 6 and the bottom plate 7, it is convenient to directly observe the flanging process of the groove insulation paper 10.

[0029] Furthermore, both the first rotating shaft 1 and the second rotating shaft 4 are rotatably mounted between the top plate 6 and the bottom plate 7 via the bearing 3, and the second rotating shaft 4 is located between the round bar 9 and the first rotating shaft 1; this facilitates the smooth rotation of the first rotating shaft 1 and the second rotating shaft 4.

[0030] Furthermore, the side of the two limiting rings 2 that are close to each other is set as the limiting bottom surface 21, and the side of the two guide rings 5 ​​that are close to each other is set as the guide bottom surface 52. Each guide bottom surface 52 has an inclined surface 51 on one side. The two limiting rings 2 limit the slotted insulating paper 10, thereby ensuring stable movement. The design of the inclined surface 51 makes it easy for the two sides of the slotted insulating paper 10 to be folded up and flipped under the action of the inclined surface 51.

[0031] Furthermore, the height difference between the two limiting bottom surfaces 21 is the same as the width dimension of the slotted insulating paper 10, and the height difference between the limiting bottom surface 21 and the corresponding guide bottom surface 52 is the height of the folded edge of the slotted insulating paper 10; the slotted insulating paper 10 moves stably along the first rotating shaft 1 between the two limiting bottom surfaces 21 of the limiting ring 2, and then bends when passing the inclined surface 51 on the guide ring 5, thereby folding up.

[0032] Furthermore, two slots are provided on the outer surfaces of the top plate 6 and the bottom plate 7. There are at least two round rods 9. The end of each round rod 9 is fixedly connected to the slot on the top plate 6 and the slot on the bottom plate 7, respectively. The distance between the two round rods 9 is the thickness of the two layers of grooved insulating paper 10. This allows the grooved insulating paper 10 to pass between the two round rods 9, so that the folded part of the grooved insulating paper 10 is squeezed and pressed tightly against the grooved insulating paper 10, thereby completing the folding and flanging process.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
