[0043] The specific embodiments of the present invention are further described in detail below with reference to the accompanying drawings and examples. The following examples are intended to illustrate the present invention but are not intended to limit the scope of the invention. It should be noted that the high temperature in the high-temperature superconductor of the present invention has a clear temperature meaning in the art. High-temperature superconductors generally refer to materials that superconduct at liquid nitrogen temperatures above 77K, and there is no ambiguity.

[0044] like Figures 1 to 4 as well as Figure 8 As shown, a preferred embodiment of the present invention provides a high-temperature superconducting coil bending and forming machine, which includes a driving assembly 1, a forming assembly 2, a pressing assembly 3 and an anti-twist tooling 4 sequentially arranged on a frame 7 along the transverse direction;

[0045] The drive assembly 1 is used to drive the high-temperature superconducting conductor to move laterally so as to sequentially pass through the forming assembly 2, the pressing assembly 3, and the anti-twist tooling 4. The forming assembly 2 includes a forming wheel 21 rotatably connected to the frame 7, and the forming wheel 21 is used to guide the high-temperature superconducting conductor into shape. The pressing assembly 3 includes a pressing wheel 31, which is slidably connected to the frame 7 to contact and bend the high-temperature superconducting conductor.

[0046] The anti-twist tooling 4 includes a connecting frame 41 rotatably connected to the frame 7, and the end of the connecting frame 41 away from the frame 7 is rotatably connected to the anti-twist frame 42, and a plurality of anti-twist parts are provided in the anti-twist frame 42, and the anti-twist parts include two anti-twist shafts 43 arranged opposite to each other. The two anti-twist shafts 43 arranged opposite to each other squeeze and fix the side walls of the high-temperature superconducting conductor to prevent the high-temperature superconducting conductor from twisting when the high-temperature superconducting coil is dropped into the mold; wherein, the rotation axis of the connecting frame 41 and the rotation axis of the anti-twist frame 42 are parallel to the central axis of the pressing wheel 31.

[0047] Specifically, in conventional technology, the high-temperature superconducting conductor passes through the driving component 1, the forming component 2, the pressing component 3 and the anti-twist tooling 4 in sequence. When the high-temperature superconducting conductor needs to be pressed down to facilitate the winding of the high-temperature superconducting coil, the pressing wheel 31 will slide on the frame 7 and abut the high-temperature superconducting conductor, thereby bending the high-temperature superconducting conductor to a preset bending radius. During the bending process of the high-temperature superconducting conductor, the connecting frame 41 and the anti-twist frame 42 in the anti-twist tooling 4 will rotate relative to the frame 7 as the high-temperature superconducting conductor bends, so that the high-temperature superconducting conductor is always between the relatively arranged anti-twist shafts 43. The relatively arranged anti-twist shafts 43 will clamp and fix the side walls on both sides of the high-temperature superconducting conductor, thereby preventing the high-temperature superconducting conductor from twisting when the high-temperature superconducting coil is molded, and thus the current-carrying capacity of the high-temperature superconducting conductor can still be guaranteed after it is wound into a high-temperature superconducting coil.

[0048] like Figure 1 、 Figure 4 and Figure 5 As shown, in some embodiments, a correction component 5 is further included, which includes a correction base 51 fixed to the frame 7. The correction base 51 is rotatably connected to a first correction wheel 52 and a second correction wheel 53 that are relatively arranged. The rotating axis of the first correction wheel 52 is parallel to the rotating axis of the second correction wheel 53 and the table surface of the frame 7.

[0049] Furthermore, the rotation axis of the forming wheel 21 is perpendicular to the table surface of the frame 7 , and the extension lines of the rotation axes of the first correction wheel 52 and the second correction wheel 53 are perpendicular to and intersect with the extension line of the rotation axis of the forming wheel 21 .

[0050] Specifically, the rotation axis of the forming wheel 21 is perpendicular to the table surface of the frame 7. Together with the first correction wheel 52 and the second correction wheel 53 arranged opposite to each other, the three surfaces of the high-temperature superconducting conductor can be squeezed and fixed, thereby ensuring the smooth bending and forming of the high-temperature superconducting conductor. It can also limit the shape of the upper and lower side surfaces of the high-temperature superconducting conductor, effectively controlling problems such as deformation of the inner hole of the high-temperature superconducting conductor during the bending process.

[0051] Furthermore, a guide wheel is provided on the frame 7, the rotation axis of the guide wheel is perpendicular to the table surface of the frame 7, and the guide wheel is arranged between the driving component 1 and the forming component 2. The guide wheel can accurately guide the high-temperature superconducting conductor output by the driving component 1 to between the forming wheel 21, the first correction wheel 52 and the second correction wheel 53.

[0052] Furthermore, the positions of the first correction wheel 52 and the second correction wheel 53 in the correction assembly 5 can be adjusted in the up-down direction and the left-right direction, thereby meeting the correction requirements of more high-temperature superconducting conductors.

[0053] like Figure 3 and Figure 8As shown, in some embodiments, the anti-twist tooling 4 further includes an upper support wheel 44 and a lower support wheel 45 arranged on the anti-twist frame 42, the axes of the upper support wheel 44 and the lower support wheel 45 are perpendicular to the axis of the anti-twist shaft 43, and the wheel surfaces of the upper support wheel 44 and the lower support wheel 45 are in contact with the high-temperature superconducting conductor and are used to guide the movement of the high-temperature superconducting conductor.

[0054] Specifically, the driving assembly 1 can continuously drive the high-temperature superconducting conductor to move laterally. When the high-temperature superconducting conductor is pressed down by the pressing wheel 31, the anti-twist tooling 4 also acts as a guiding component to guide the transportation of the high-temperature superconducting conductor. In this process, the upper support wheel 44 and the lower support wheel 45 in the anti-twist tooling 4 play a key guiding role in the movement of the high-temperature superconducting conductor. When the anti-twist shaft 43 clamps the left and right side walls of the high-temperature superconducting conductor to prevent the high-temperature superconducting conductor from twisting, the upper support wheel 44 and the lower support wheel 45 can make the movement of the high-temperature superconducting conductor smoother and more natural, avoiding the problem of the high-temperature superconducting conductor being difficult to move under the clamping of the anti-twist shaft 43.

[0055] like Figure 2 and Figure 7 As shown, in some embodiments, the pressing assembly 3 includes a worm gear elevator 32 and a slide trough 34 provided on the frame 7. The output end of the worm gear elevator 32 is connected to the pressing wheel 31, and the input end is connected to the first motor 33. The first motor 33 drives the pressing wheel 31 through the worm gear elevator 32 to slide in the slide trough 34 to contact and bend the high-temperature superconducting conductor.

[0056] Specifically, a slide groove 34 is provided on the table surface of the frame 7, and the middle part of the pressing wheel 31 is connected to the output end of the worm gear elevator 32 through the shaft passing through the slide groove 34. When it is necessary to press down the high-temperature superconducting conductor for winding, the first motor 33 drives the output end of the worm gear elevator 32 to move, thereby controlling the pressing wheel 31 to slide in the slide groove 34. The pressing wheel 31 approaches the high-temperature superconducting conductor and presses the high-temperature superconducting conductor, so that the high-temperature superconducting conductor is pressed down to a preset radius, thereby realizing the pressing process of the high-temperature superconducting conductor.

[0057] like Figures 1 to 4 As shown, in the embodiment, the driving assembly 1 includes a power assembly and a transmission assembly, and the power assembly is used to provide power to the transmission assembly to transport the high-temperature superconducting conductor;

[0058] The transmission assembly includes a plurality of transition gears 11 and a plurality of drive gears 12 alternately arranged along the lateral movement direction of the high-temperature superconducting conductor. The transition gear 11 is arranged between two adjacent drive gears 12 to transmit power. The transition gear 11 or the drive gear 12 located at one end of the transmission assembly is connected to the power assembly.

[0059] The driving gears 12 are connected to the driving wheels 13 through the rotating shaft. The driving wheels 13 are arranged on the table of the frame 7. The frame 7 is provided with a pressure wheel 14 corresponding to the driving wheel 13. The pressure wheel 14 corresponds to the driving wheel in number and position. The pressure wheel 14 is used to abut the high-temperature superconducting conductor against the driving wheel 13 so that the driving wheel 13 can drive the high-temperature superconducting conductor to move.

[0060] Furthermore, the pressure wheel 14 is connected to a pressure frame 15, which is slidably connected to the frame 7. The pressure frame 15 is connected to a pressure screw 16, which is used to drive the pressure frame 15 to slide relative to the frame 7, thereby driving the pressure wheel 14 to move closer to or away from the driving wheel 13.

[0061] Furthermore, the power assembly includes a second motor 17 provided on the frame 7 , and an output end of the second motor 17 is connected to a reducer 18 and a power gear 19 in sequence, and the power gear 19 is connected to the transmission assembly.

[0062] Specifically, when winding the high-temperature superconducting conductor, it is necessary to continuously transport the high-temperature superconducting conductor to the molding assembly 2 and the pressing assembly 3. At this time, the output end of the second motor 17 drives the power gear 19 to rotate through the reducer 18, and the power gear 19 is engaged with the transition gear 11, and the transition gear 11 is engaged with the drive gear 12. Based on this, the second motor 17 drives the drive gear 12 to rotate through the power gear 19 and the transition gear 11, thereby driving the drive wheel 13 to rotate, and the pressure wheel 14 presses the high-temperature superconducting conductor on the drive wheel 13, and the drive wheel 13 drives the high-temperature superconducting conductor to move to the molding assembly 2 through friction. In this process, the drive wheel 13 and the pressure wheel 14 will rotate simultaneously to ensure the smooth movement of the high-temperature superconducting conductor.

[0063] In addition, depending on the size of the high-temperature superconducting conductor used, in order to ensure sufficient contact pressure between the high-temperature superconducting conductor and the driving wheel 13 to generate sufficient friction to drive the high-temperature superconducting conductor to move, in actual use, it is also necessary to first rotate the clamping screw 16 to drive the clamping frame 15 to move on the frame 7, thereby controlling the clamping wheel 14 to approach or move away from the driving wheel 13, and adjusting the pressure applied to the high-temperature superconducting conductor by the clamping wheel 14, so that the friction between the driving wheel 13 and the high-temperature superconducting conductor is greater, and the driving wheel 13 can better drive the high-temperature superconducting conductor to move.

[0064] In a specific embodiment, two transition gears 11 are provided, three driving gears 12 and three driving wheels 13 are provided, and three corresponding pressing wheels 14 are also provided.

[0065] like Figure 1 and Figure 6As shown, in some embodiments, a metering device 6 is further included. The metering device 6 includes a metering base 61 fixed to the frame 7. The metering base 61 is provided with a slide rail 62. The slide rail 62 is slidably connected to a metering mounting seat 63. A measuring roller 64 is provided in the metering mounting seat 63. The measuring roller 64 is connected to a metering instrument 65.

[0066] A guide rod 66 is connected to the side of the metering mount 63 away from the measuring roller 64. The other end of the guide rod 66 passes through a baffle 67 provided on the metering base 61. The guide rod 66 is sleeved with a spring 68. The two ends of the spring 68 respectively abut the metering mount 63 and the baffle 67.

[0067] Specifically, when bending a high-temperature superconducting conductor, the bending position needs to be precisely controlled to facilitate winding of the high-temperature superconducting conductor. Therefore, a metering device 6 is provided. In a specific embodiment, the metering device 6 is provided between two adjacent drive wheels 13. Driven by a spring 68, the metering base 61 can move along the slide rail 62 toward the high-temperature superconducting conductor until the measuring roller 64 on the metering base 61 contacts the high-temperature superconducting conductor. When the drive wheel 13 drives the high-temperature superconducting conductor to move laterally, the high-temperature superconducting conductor contacts the measuring roller 64, which drives the measuring roller 64 to rotate. Thus, the metering instrument 65 connected to the measuring roller 64 can accurately measure the distance moved by the high-temperature superconducting conductor.

[0068] The present invention also provides a method for winding a high-temperature superconducting conductor, comprising the following steps:

[0069] S1. First, adjust the distance between the pressing wheel and the driving wheel by using the pressing screw so that the high-temperature superconducting conductor can be in close contact with the driving wheel under the pressure of the pressing wheel;

[0070] S2, then start the second motor, which drives the driving gear to rotate through the transition gear and then drives the driving wheel to rotate, thereby driving the high-temperature superconducting conductor to move laterally;

[0071] S3. When the high-temperature superconducting conductor is bent and formed, the first motor drives the pressing wheel to move in the slide groove through the worm gear elevator. When the pressing wheel contacts the high-temperature superconducting conductor, the first motor is paused and the pressing distance is reset;

[0072] S4, further starting the first motor to drive the pressing wheel to a preset pressing distance, so that the high-temperature superconducting conductor is bent to a preset radius;

[0073] S5. Turn off the first motor and start the second motor to continue moving the high-temperature superconducting conductor and bend it. The high-temperature superconducting conductor is bent at the forming wheel, and the first correction wheel and the second correction wheel are used to perform correction processing, so as to effectively control the deformation of the inner hole of the high-temperature superconducting conductor during the bending process.

[0074] S6. Finally, when the high-temperature superconducting coil is molded, the connection frame and the anti-torsion frame in the anti-torsion tooling rotate as the high-temperature superconducting conductor bends, and the anti-torsion shaft clamps and fixes the side wall of the high-temperature superconducting conductor to prevent the high-temperature superconducting conductor from twisting during the high-temperature superconducting coil mold dropping process.

[0075] Specifically, in the process of winding the high-temperature superconducting coil, it is necessary to first adjust the distance between the clamping wheel 14 and the driving wheel 13 to ensure that the driving wheel 13 drives the high-temperature superconducting conductor to move laterally normally, and then adjust the positions of the first correction wheel 52, the second correction wheel 53 and the forming wheel 21 so that the high-temperature superconducting conductor can be bent and formed. Subsequently, the driving component 1 drives the high-temperature superconducting conductor to continuously move toward the forming component 2. The high-temperature superconducting conductor is bent and formed at the forming wheel 21, and then the high-temperature superconducting conductor is bent to a preset radius under the action of the pressing wheel 31. The connecting frame 41 and the anti-torsion frame 42 in the anti-torsion tooling 4 can rotate with the bent high-temperature superconducting conductor, continuously guiding the movement of the high-temperature superconducting conductor. At the same time, the anti-torsion shaft 43 can further prevent the high-temperature superconducting conductor from twisting during the high-temperature superconducting coil molding process.

[0076] In summary, an embodiment of the present invention provides a high-temperature superconducting coil bending and winding machine and a winding method, which effectively controls the deformation of the inner hole of the high-temperature superconducting conductor by arranging a first correction wheel 52 and a second correction wheel 53 in the forming assembly 2, and then realizes the bending of the high-temperature superconducting conductor by pressing the wheel 31. As the high-temperature superconducting conductor bends, the connecting frame 41 and the anti-twist frame 42 also rotate accordingly, thereby continuously guiding the high-temperature superconducting conductor. At the same time, the two sets of anti-twist shafts 43 arranged relatively to each other can clamp and fix the side walls of the high-temperature superconducting conductor, further avoiding the problem of self-twist of the high-temperature superconducting conductor during the molding process.

[0077] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.

10. A method for winding a high-temperature superconducting coil, using the high-temperature superconducting coil bending and forming machine according to any one of claims 1 to 9, characterized in that: The following steps are involved: S1. First, adjust the distance between the pressing wheel and the driving wheel by using the pressing screw so that the high-temperature superconducting conductor can be in close contact with the driving wheel under the pressure of the pressing wheel; S2, then start the second motor, which drives the driving gear to rotate through the transition gear and then drives the driving wheel to rotate, thereby driving the high-temperature superconducting conductor to move laterally; S3. When the high-temperature superconducting conductor is bent and formed, the first motor drives the pressing wheel to move in the slide groove through the worm gear elevator. When the pressing wheel contacts the high-temperature superconducting conductor, the first motor is paused and the pressing distance is reset; S4, further starting the first motor to drive the pressing wheel to a preset pressing distance, so that the high-temperature superconducting conductor is bent to a preset radius; S5. Turn off the first motor and start the second motor to continue moving the high-temperature superconducting conductor and bending it into shape. The high-temperature superconducting conductor is bent into shape at the forming wheel, and the first correction wheel and the second correction wheel are used to perform correction processing, so that the deformation of the high-temperature superconducting conductor during the bending process can be well controlled. S6. Finally, when the high-temperature superconducting coil is dropped into the mold, the connection frame and the anti-torsion frame in the anti-torsion tooling rotate as the high-temperature superconducting conductor bends, and the anti-torsion shaft clamps and fixes the side wall of the high-temperature superconducting conductor to prevent the high-temperature superconducting conductor from twisting during the drop-molding process.
