Description

Technical Field

[0001] This utility model relates to the field of magnetic levitation flywheel technology, specifically to a shaping device for a magnetic bearing coil. Background Technology

[0002] Initially, mechanical bearings were typically used to secure flywheels in flywheel energy storage devices. However, with the development of flywheel energy storage devices and the gradual increase in installed capacity, the demands on bearing performance and sensitivity have also increased. To improve energy utilization, reducing the friction of large flywheels is a critical design challenge for large flywheel energy storage devices. To reduce this friction, magnetic bearings are often used instead of mechanical bearings to reduce friction and improve energy utilization. However, when using large magnetic bearings instead of mechanical bearings, it is challenging to wind the wires into uniformly sized and shaped coils on the forming mold. Furthermore, after coil shaping, the process of removing the coil from the mold often results in incomplete coil setting, leading to wire deformation and dispersion, which affects the coil's performance and may even render it unusable.

[0003] Therefore, there is an urgent need for a shaping device for magnetic bearing coils that can shape the coils and facilitate coil handling. Utility Model Content

[0004] In view of this, the present invention proposes to use a side shaping plate and an end shaping plate to shape the coil wound on the shaping mold.

[0005] The technical solution of this utility model is implemented as follows: a shaping device for a magnetic bearing coil includes a base, on which a shaping mold and at least one side shaping plate and an end shaping plate are provided. A coil is wound on the shaping mold. The side shaping plate is away from or close to the shaping mold with the coil wound on it, and shapes the coil wound on the side of the shaping mold. The end shaping plate is away from or close to the shaping mold with the coil wound on it, and shapes the coil wound at the end of the shaping mold.

[0006] Based on the above technical solutions, preferably, the shaping mold includes a main shaping body and a mating body, wherein the mating body and the main shaping body are combined with each other, and the coil winding is jointly arranged on the main shaping body and the mating body.

[0007] Based on the above technical solutions, preferably, the mating body is provided with a mating step, and one end of the main shaping body is provided on the mating step.

[0008] Based on the above technical solutions, preferably, the base is provided with a mating pin, one end of which is fixedly set on the base and the other end passes through the mating body and the main shaping body in sequence.

[0009] Based on the above technical solutions, preferably, the base is provided with a positioning block, and the main shaping body is arranged around the positioning block.

[0010] Based on the above technical solutions, preferably, the bottom of the main shaping body is provided with a plurality of shaping protrusions, and the base is provided with a plurality of shaping grooves, wherein the shaping protrusions and the shaping grooves are configured to cooperate with each other.

[0011] Based on the above technical solutions, preferably, the base is provided with an end slide, and the end shaping plate is configured in conjunction with the end slide.

[0012] Based on the above technical solutions, preferably, the base is provided with a side slide rail, and the side shaping plate is configured in conjunction with the side slide rail.

[0013] Based on the above technical solutions, preferably, it also includes a cover plate, which covers the forming mold. The cover plate has a first mating tooth on the side near the side forming plate, and a second mating tooth on the side of the side forming plate that mates with the cover plate. The first mating tooth and the second mating tooth are mated together.

[0014] Based on the above technical solutions, preferably, it also includes a side power device, a side push block, an end power device, and an end push block. The side push block is disposed between the side shaping plate and the side power device, and the side power device drives the side push block and the side shaping plate away from or closer to the shaping mold. The end push block is disposed between the end shaping plate and the end power device, and the end power device drives the end push block and the end shaping plate away from or closer to the shaping mold. Both the side power device and the end power device are fixedly disposed on the base.

[0015] The shaping device for magnetic bearing coils of this utility model has the following advantages over the prior art: The wire is wound around the forming mold to form a coil. The side forming plate of the forming mold is used to squeeze and shape the coil on the side of the forming mold, away from or close to the forming mold with the coil, so that the coil is more compact and the shape is more in line with the use requirements. The end forming plate of the forming mold is used to squeeze and shape the coil on the side of the forming mold, away from or close to the forming mold with the coil, so that the coil is more compact and the shape is more in line with the use requirements. Since the shaping of the coil requires shaping operations on two sides and two end faces, this technical solution includes at least one side shaping plate and one end shaping plate. In order to reduce the shaping time, two side shaping plates and two end shaping plates are included. The shaping mold is provided with one side shaping plate on each side and one end shaping plate on each end face. The shaping mold is a split design. After the coil is shaped on the shaping mold, the main shaping body and the mating body can be separated from the coil one by one. This reduces the difficulty of separating the shaping mold from the coil after the coil is shaped and avoids the coil from damaging its original shape again during the separation process from the shaping mold. The mating pin connects the mating body and the main shaping body into a whole, making separation easier. The coil will not cause relative movement between the mating body and the main shaping body during winding and shaping. The cover plate is used to prevent the coil wound on the forming mold from being detached from the forming mold at the end away from the base due to external force during the forming process. In this embodiment, the cover plate presses on the forming mold by its own weight. Depending on the actual needs, the cover plate and the forming mold can be fastened with bolts or weights can be added to the cover plate to prevent the cover plate from being lifted up by excessive force in the direction perpendicular to the base plate during the coil forming process.

Detailed Implementation

[0018] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them.

[0019] like Figure 1-6 As shown, a shaping device for a magnetic bearing coil includes a base 1, on which a shaping mold 2 and at least one side shaping plate 3 and an end shaping plate 4 are disposed. A coil 5 is wound on the shaping mold 2. The side shaping plate 3 is away from or close to the shaping mold 2 with the coil wound on it, and shapes the coil wound on the side of the shaping mold 2. The end shaping plate 4 is away from or close to the shaping mold 2 with the coil wound on it, and shapes the coil wound at the end of the shaping mold 2. The wire is wound around the forming mold 2 to form a coil. The side forming plate 3 on the side of the forming mold 2 is used to squeeze and shape the coil on the side of the forming mold 2, away from or close to the forming mold 2 with the coil, so that the coil is more compact and the shape is more in line with the use requirements. The end forming plate 4 at the end of the forming mold 2 is used to squeeze and shape the coil on the side of the forming mold 2, away from or close to the forming mold 2 with the coil, so that the coil is more compact and the shape is more in line with the use requirements. Since the coil shaping requires shaping operations on two sides and two end faces, this technical solution includes at least one side forming plate 3 and one end forming plate 4. In order to reduce the shaping time, there are two side forming plates 3 and two end forming plates 4. One side forming plate 3 is provided on each side of the forming mold 2 and one end forming plate 4 is provided on each end face.

[0020] The shaping mold 2 includes a main shaping body 21 and a mating body 22.

The mating body 22 is provided with a mating step 221, and one end of the main shaping body 21 is set on the mating step 221. The shaping mold 2 is a split design. After the coil is shaped on the shaping mold 2, the main shaping body 21 and the mating body 22 can be separated from the coil one by one. This reduces the difficulty of separating the shaping mold 2 from the coil 5 after the coil 5 is shaped, and avoids the coil 5 from being damaged again during the separation process from the shaping mold 2.

The positioning block 12 is fixedly set on the base 1, and the position of the positioning block 12 is fixed. The main shaping body 21 cooperates with the positioning block 12 to ensure that the shaping mold 2 with the coil 5 is stable under shaping force, and to avoid the shaping mold 2 being subjected to excessive force on one side or one end, which would lead to poor coil shaping or failure.

[0023] The main shaping body 21 has several shaping protrusions 211 at its bottom, and the base 1 has several shaping grooves 13. The shaping protrusions 211 and the shaping grooves 13 are configured to cooperate with each other. When the main shaping body 21 and the base 1 are configured to cooperate, the difficulty is reduced, the cooperation accuracy is improved, and the shaping accuracy of the coil 5 in the shaping mold 2 is higher.

[0024] The system also includes a cover plate 6, which covers the forming mold 2. The cover plate 6 has a first mating tooth 61 on the side near the side forming plate 3, and a second mating tooth 31 on the side of the side forming plate 3 that mates with the cover plate 6. The first mating tooth 61 and the second mating tooth 31 are engaged. The cover plate 6 is used to prevent the coil 5 wound on the forming mold 2 from being detached from the end of the forming mold 2 away from the base 1 due to external force during the forming process. In this embodiment, the cover plate 6 rests on the forming mold 2 by its own weight. Depending on actual needs, the cover plate 6 can be fastened to the forming mold 2 with bolts or weights can be added to the cover plate 6 to prevent the cover plate 6 from being lifted by excessive force perpendicular to the base plate 1 during the forming process of the coil 5.

[0025] It also includes a side power device 71, a side push block 72, an end power device 81, and an end push block 82. The side push block 72 is disposed between the side shaping plate 3 and the side power device 71, and the side power device 71 drives the side push block 72 and the side shaping plate 3 away from or towards the shaping mold 2. The end push block 82 is disposed between the end shaping plate 4 and the end power device 81, and the end power device 81 drives the end push block 82 and the end shaping plate 4 away from or towards the shaping mold 2. Both the side power device 71 and the end power device 81 are fixedly mounted on the base 1. An end slide rail 15 is provided on the base 1, and the end shaping plate 4 is configured to cooperate with the end slide rail 15. A side slide rail 14 is provided on the base 1, and the side shaping plate 3 is configured to cooperate with the side slide rail 14.
