[0034] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.
[0035] The following is for reference. Figures 1-6 An assembly apparatus 100 for a vacuum pressure impregnation mold 200 according to an embodiment of the present invention is described. The impregnation mold 200 includes a plurality of mold units 201, which are assembled to define a mounting cavity 202 for mounting a magnet coil. Each mold unit 201 has a mounting flange 203. Any two adjacent mold units 201 that are assembled together are welded together through the mounting flanges 203 of the two mold units 201. The assembly apparatus 100 includes:
[0036] Multiple support mechanisms 10 are provided, each used to support a corresponding mold unit 201. Each support mechanism 10 includes two support platforms 12 and two support plates 13. The two support platforms 12 are spaced apart along the height direction of the support mechanism 10. The two support plates 13 are assembled between the two support platforms 12. The two support plates 13 are opposite to each other and spaced apart along a first direction, so that the two support platforms 12 and the two support plates 13 together define an installation space for the corresponding mold unit 201 to pass through. The two support plates 13 are used to contact the corresponding mold unit 201, and the position of the two support plates 13 relative to the support platforms 12 along the first direction is adjustable. The first direction is perpendicular to the height direction of the support mechanism 10.
[0037] The assembly device 100 for the vacuum pressure immersion mold 200 can be used in the manufacturing process of magnets for tokamak nuclear fusion devices. During the vacuum pressure immersion process, the immersion mold 200 needs to provide a well-sealed internal environment. Due to the large size of the magnet coil and the fact that the immersion mold 200 needs to completely enclose the magnet coil, the immersion mold 200 needs to be divided into many pieces for on-site welding. The weld length can reach hundreds of meters, and the welding quality requirements are extremely high. It is necessary to ensure that the weld strength and quality meet the requirements of leak detection and vacuum pressure testing, and that the weld does not have any problems even if the vacuum pressure immersion continues for more than a month.
[0038] The immersion mold 200 includes multiple mold units 201. In some embodiments of the present invention, the immersion mold 200 may include two, three, four, ten, or other numbers of mold units 201. However, the present invention is not limited to this. The immersion mold 200 may also include other numbers of mold units 201, as long as the immersion mold 200 includes multiple mold units 201. The specific number of mold units 201 can be reasonably set according to the size of the magnet coil.
[0039] Multiple mold units 201 are assembled together to define a mounting cavity 202 for mounting a magnet coil. The magnet coil often has a symmetrical or irregular structure. By combining multiple mold units 201, a special mold unit can be designed for the arc, stepped surface or irregular cross-section of the magnet coil to match the circumferential curved surface of the magnet coil and avoid local extrusion deformation.
[0040] like Figure 6 As shown, each mold unit 201 has an assembly flange 203. Any two adjacent mold units 201 that are assembled together are connected by lap welding through the assembly flanges 203 of the two mold units 201. This can replace the splicing welding method between two mold units 201, thereby increasing the distance between the weld and the magnet coil in the mounting cavity 202. This can reduce the impact of high welding temperature on the magnet coil, avoid aging of the magnet coil insulation material or loss of superconductivity, increase the structural strength of the impregnation mold 200, reduce the risk of welding deformation, and solve the problem of oxidation on the back of the weld. Furthermore, this invention uses a DC pulse argon arc welding self-fusion (no wire) welding method to weld the assembly flange 203, which can effectively reduce the welding heat input and further reduce the impact of high welding temperature on the magnet coil.
[0041] The assembly device 100 includes a plurality of support mechanisms 10. In some embodiments of the present invention, the assembly device 100 may include two, three, four, ten or other numbers of support mechanisms 10. However, the present invention is not limited thereto. The assembly device 100 may also include other numbers of support mechanisms 10, as long as the assembly device 100 includes a plurality of support mechanisms 10.
[0042] The number of support mechanisms 10 is the same as the number of mold units 201. Multiple support mechanisms 10 are used to support the corresponding mold units 201. During welding, the mold units 201 are prone to thermal deformation (such as bending and twisting) due to localized heating. The support mechanisms 10 can restrict the degrees of freedom of the mold units 201 through rigid fixing or flexible clamping, reduce the amount of deformation of the mold units 201, and ensure the accuracy of the weld position. The support mechanisms 10 can also quickly dissipate welding heat, reduce the temperature gradient of the weld and heat-affected zone, and further reduce the impact of high welding temperature on the magnet coil. For large mold units 201, the support mechanisms 10 also have an anti-tipping function to prevent the mold unit 201 from tipping over due to the shift of the center of gravity during welding, avoiding personal injury and equipment damage.
[0043] like Figure 2 As shown, the first direction is the X-direction, which is perpendicular to the height direction of the support mechanism 10. The support mechanism 10 includes two support platforms 12 and two support plates 13. The support plates 13 and support platforms 12 are adapted to the shape of the corresponding mold unit 201 so that the support plates 13 and support platforms 12 fit the corresponding mold unit 201, avoiding indentations on the mold unit 201 due to shape mismatch, and also improving the positional accuracy of the corresponding mold unit 201 to improve welding accuracy.
[0044] Two support platforms 12 are spaced apart along the height direction of the support mechanism 10. Two support plates 13 are assembled between the two support platforms 12. The two support plates 13 are opposite to each other and spaced apart along a first direction, so that the two support platforms 12 and the two support plates 13 together define an installation space for the corresponding mold unit 201 to pass through. The two support plates 13 are used to contact the corresponding mold unit 201 and can restrict the corresponding mold unit 201 within the support mechanism 10, so as to prevent the corresponding mold unit 201 from being displaced during welding and causing welding deformation.
[0045] Furthermore, the positions of the two support plates 13 relative to the support platform 12 along the first direction are adjustable, which can further adjust the position of the corresponding mold unit 201, ensure the accurate welding position of the mold unit 201, thereby improving the welding quality and precision of the mold unit 201 and effectively reducing the risk of welding deformation and failure.
[0046] The assembly apparatus 100 for a vacuum pressure impregnation mold 200 according to an embodiment of the present invention can increase the structural strength of the impregnation mold 200 by welding any two adjacent mold units 201 that are assembled together through the assembly flange 203 of the two mold units 201. It can also increase the distance between the weld and the magnet coil, and solve problems such as oxidation on the back of the weld and the influence of high welding temperature on the magnet coil. By setting a support mechanism 10 to support the corresponding mold unit 201, the position of the corresponding mold unit 201 can be adjusted to ensure the accurate welding position of the mold unit 201, thereby improving the welding quality and precision of the mold unit 201 and effectively reducing the risk of welding deformation and failure.
[0047] According to some embodiments of the present invention, such as Figure 2 As shown, the support mechanism 10 also includes two position adjustment structures 20, which are arranged one-to-one with the two support plates 13. The position adjustment structures 20 are used to adjust the position of the corresponding support plate 13 located above relative to the upper support platform 12 along the first direction.
[0048] Among them, such as Figure 2 As shown, the immersion mold 200 can be constructed as a ring or similar ring structure. One of the two support plates 13 is located on the inner ring surface of the immersion mold 200, and the other is located on the outer ring surface of the immersion mold 200. The two support plates 13 are positioned opposite each other along the first direction to clamp the corresponding mold unit 201 within the two support plates 13. Two position adjustment structures 20 are located on the side of the two support plates 13 away from the immersion mold 200, and the position adjustment structures 20 are used to adjust the position of the corresponding support plate 13 relative to the upper support platform 12 along the first direction. This can adjust the position of the corresponding mold unit 201 relative to the upper support platform 12 along the first direction, and further adjust the position of the corresponding mold unit 201 to ensure accurate welding position of the mold unit 201. This can improve the welding quality and precision of the mold unit 201 and effectively reduce the risk of welding deformation and failure.
[0049] According to some embodiments of the present invention, the position adjustment structure 20 is located on the side of the respective support plate 13 opposite to the other support plate 13, and the position adjustment structure 20 is fixed to at least one of the two support platforms 12.
[0050] The position adjustment structure 20 is located on the side of the corresponding support plate 13 away from the other support plate 13. That is, the two position adjustment structures 20 are respectively located on the side of the two support plates 13 away from the immersion mold 200, so that the two position adjustment structures 20 can adjust the position of the corresponding support plate 13 relative to the upper support platform 12 in the first direction, and thus can adjust the position of the corresponding mold unit 201 relative to the upper support platform 12 in both directions in the first direction, further ensuring the accuracy of the welding position of the mold unit 201, thereby further improving the welding quality and precision of the mold unit 201, and effectively reducing the risk of welding deformation and failure.
[0051] The position adjustment structure 20 is fixed to at least one of the two support platforms 12. In some embodiments of the present invention, the position adjustment structure 20 can be fixed to the upper support platform 12, or the position adjustment structure 20 can be fixed to the lower support platform 12, or the position adjustment structure 20 can be fixed between the upper support platform 12 and the lower support platform 12. The position can be reasonably set according to the actual situation. As a specific embodiment of the present invention, the position adjustment structure 20 can be fixed between the upper support platform 12 and the lower support platform 12. After the position of the corresponding mold unit 201 is adjusted by the position adjustment structure 20, fixing the position adjustment structure 20 between the upper support platform 12 and the lower support platform 12 can more stably maintain the corresponding mold unit 201 at a precise welding position, preventing displacement of the corresponding mold unit 201. This further improves the welding quality and precision of the mold unit 201 and effectively reduces the risk of welding deformation and failure.
[0052] According to some embodiments of the present invention, such as Figure 2 As shown, the position adjustment structure 20 may include: a connecting column 21, which extends along the height direction of the support mechanism 10 and is fixed to at least one of the two support platforms 12. The connecting column 21 is provided with a first position adjustment part 22, which passes through the connecting column 21 along a first direction. The end of the first position adjustment part 22 facing the corresponding support plate 13 contacts the support plate 13. The position of the corresponding support plate 13 is adjusted by moving the first position adjustment part 22 along the first direction.
[0053] The connecting column 21 extends along the height direction of the support mechanism 10 and is fixed to at least one of the two support platforms 12. In the embodiments of the present invention, the connecting column 21 can be fixedly connected to one of the two support platforms 12, or the connecting column 21 can be fixedly connected to both support platforms 12. It can be reasonably set according to the actual situation.
[0054] In a specific embodiment of the present invention, the connecting column 21 is fixedly connected to both support platforms 12. Specifically, after the position of the connecting column 21 is adjusted to the correct position, the connecting column 21 is fixedly connected to both support platforms 12, which can more stably maintain the connecting column 21 in the accurate position, prevent the connecting column 21 from shifting, and further improve the support stability and reliability of the support mechanism 10.
[0055] The connecting column 21 is provided with a first position adjustment part 22, which can be constructed as a bolt, screw, or other structure. The first position adjustment part 22 passes through the connecting column 21 along a first direction, and the end of the first position adjustment part 22 facing the corresponding support plate 13 contacts the support plate 13. By moving the first position adjustment part 22 along the first direction, the corresponding support plate 13 can be moved along the first direction to adjust the position of the corresponding support plate 13.
[0056] Specifically, when the first position adjustment part 22 moves toward the corresponding support plate 13 in the first direction, the end of the first position adjustment part 22 facing the corresponding support plate 13 abuts against the support plate 13 and pushes the corresponding support plate 13 to move, and locks the corresponding support plate 13 in a certain position.
[0057] When the first position adjustment part 22 moves away from the corresponding support plate 13 along the first direction, a gap can be generated between the end of the first position adjustment part 22 facing the corresponding support plate 13 and the support plate 13, so that the support plate 13 can move relative to the first position adjustment part 22, thereby enabling the position of the corresponding support plate 13 to be readjusted.
[0058] According to some embodiments of the present invention, such as Figure 2 As shown, the connecting column 21 may be provided with multiple first position adjustment parts 22, and the multiple first position adjustment parts 22 are arranged sequentially along the height direction of the support mechanism 10.
[0059] The connecting post 21 is provided with a plurality of first position adjustment parts 22. In some embodiments of the present invention, the connecting post 21 may be provided with two, three, four or other numbers of first position adjustment parts 22. However, the present invention is not limited to this. The connecting post 21 may also be provided with other numbers of first position adjustment parts 22, as long as the connecting post 21 is provided with a plurality of first position adjustment parts 22.
[0060] The specific number of the first position adjustment parts 22 can be reasonably set according to the length of the connecting column 21. As a specific embodiment of the present invention, there can be five first position adjustment parts 22. The five first position adjustment parts 22 are arranged evenly along the height direction of the support mechanism 10. With this arrangement, the position of the connecting column 21 can be adjusted evenly along the first direction, avoiding the displacement of the position of the connecting column 21 due to excessive local fastening force. This ensures the uniformity of the support force of the support plate 13, so as to adjust the corresponding mold unit 201 to the accurate position and play the role of supporting the corresponding mold unit 201.
[0061] According to some embodiments of the present invention, the connecting post 21 is formed with a threaded hole, the first position adjusting part 22 is an adjusting rod, the outer peripheral wall of the adjusting rod is formed with an external thread, the adjusting rod passes through the threaded hole, and the adjusting rod is moved along the first direction by rotating the adjusting rod.
[0062] The connecting column 21 may have a threaded hole, and the first position adjustment part 22 is an adjustment rod. The outer peripheral wall of the adjustment rod has an external thread, and the adjustment rod passes through the threaded hole. By rotating the adjustment rod, the adjustment rod can be moved along the first direction. It can be adjusted directly by hand without the need for an external drive device, which can effectively reduce the position adjustment cost of the connecting column 21. In addition, the thread adjustment accuracy is high, which is conducive to improving the position adjustment accuracy of the support plate 13, and thus indirectly improving the position adjustment accuracy of the corresponding mold unit 201, so as to effectively improve the welding position accuracy of the corresponding mold unit 201.
[0063] In some embodiments of the present invention, the connecting post 21 and the corresponding support plate 13 are parallel, which enables each connecting post 21 to make precise adjustment to the corresponding support plate 13, and can further effectively ensure that the support plate 13 fits with the corresponding mold unit 201. This not only further improves the positional accuracy of the corresponding mold unit 201 to improve the welding accuracy, but also reduces the risk of the support plate 13 causing indentations on the mold unit 201.
[0064] According to some embodiments of the present invention, such as Figure 2 As shown, the connecting column 21 is located between two support platforms 12. The end of the connecting column 21 has a first mounting hole, and the support platform 12 has a second mounting hole. The first mounting hole and the second mounting hole are opposite each other along the height direction of the support mechanism 10. The connecting column 21 is fixed to the corresponding support platform 12 by passing through the second mounting hole and assembling it in the first mounting hole through the first fastener 25.
[0065] The connecting column 21 is located between the two support platforms 12. The end of the connecting column 21 has a first mounting hole, and the support platform 12 has a second mounting hole. The first mounting hole and the second mounting hole are opposite each other along the height direction of the support mechanism 10. The connecting column 21 is fixed to the corresponding support platform 12 by passing through the second mounting hole and assembling it into the first mounting hole. This can not only fix the connecting column 21 more stably, but also limit the displacement of the support plate 13 and the connecting column 21 along the height direction of the support mechanism 10 by the support platform 12, thereby stably defining the installation space for the corresponding mold unit 201 to pass through.
[0066] According to some embodiments of the present invention, such as Figure 2 As shown, at least one end of the connecting column 21 is provided with a mounting plate 23. The side edges of the mounting plate 23 and the corresponding side support platform 12 are opposite to each other and spaced apart. The mounting plate 23 is provided with a plurality of second position adjustment parts 24. The plurality of second position adjustment parts 24 are arranged along the side edge. The end of each second position adjustment part 24 facing the corresponding support platform 12 contacts the support platform 12. By moving the second position adjustment part 24 toward or away from the corresponding support platform 12, the connecting column 21 is rotated about the height direction of the support mechanism 10 to adjust the relative position of the connecting column 21 and the corresponding support plate 13.
[0067] In this invention, at least one end of the connecting column 21 is provided with a mounting plate 23. In some embodiments of the invention, the mounting plate 23 and the connecting column 21 can be fixedly connected by welding, or the mounting plate 23 and the connecting column 21 can be integrally formed. However, the invention is not limited to this. The connecting column 21 and the mounting plate 23 can also be fixedly connected by other means, as long as at least one end of the connecting column 21 is provided with a mounting plate 23.
[0068] As a specific embodiment of the present invention, both ends of the connecting column 21 are provided with mounting plates 23. The side edges of the mounting plates 23 and the corresponding side support platforms 12 are opposite to each other and spaced apart. The mounting plates 23 are provided with a plurality of second position adjustment parts 24. In some embodiments of the present invention, the mounting plates 23 may be provided with two, three, four or other numbers of second position adjustment parts 24, but the present invention is not limited to this. As long as the mounting plates 23 are provided with a plurality of second position adjustment parts 24, it is acceptable.
[0069] As a specific embodiment of the present invention, each mounting plate 23 is provided with two second position adjustment parts 24. The two second position adjustment parts 24 are evenly arranged on the mounting plate 23 along the circumference of the support plate 13. The two second position adjustment parts 24 are arranged along the side edge. The end of each second position adjustment part 24 facing the corresponding support platform 12 is in contact with the support platform 12. By moving the second position adjustment part 24 toward or away from the corresponding support platform 12, the connecting column 21 is rotated around the height direction of the support mechanism 10 to adjust the relative position of the connecting column 21 and the corresponding support plate 13.
[0070] Specifically, when one of the two second position adjustment parts 24 moves toward the corresponding support platform 12, the connecting column 21 rotates toward this second position adjustment part 24 about the height direction of the support mechanism 10. When one of the two second position adjustment parts 24 moves away from the corresponding support platform 12, the connecting column 21 rotates toward the other second position adjustment part 24 about the height direction of the support mechanism 10, so as to adjust the position of the connecting column 21 along the circumferential direction of the corresponding support plate 13, so as to ensure that the connecting column 21 is parallel to the corresponding support plate 13, thereby ensuring that the corresponding support plate 13 and the corresponding mold unit 201 fit together.
[0071] According to some embodiments of the present invention, such as Figure 2 As shown, a support base 14 is fixedly provided on the lower support platform 12. The length of the support base 14 along the height direction of the support mechanism 10 is adjustable to adjust the height of the lower support platform 12.
[0072] The lower support platform 12 is fixedly provided with a support base 14. In some embodiments of the present invention, the support platform 12 and the support base 14 can be fixedly connected by threads, or the support platform 12 and the support base 14 can be fixedly connected by a sliding mechanism. However, the present invention is not limited to this. The support platform 12 and the support base 14 can also be fixedly connected by other means, as long as the lower support platform 12 is fixedly provided with a support base 14.
[0073] The length of the support base 14 along the height direction of the support mechanism 10 is adjustable to adjust the height of the support platform 12 below. This allows the height of the support mechanism 10 to be adjusted so that the height of the support platform 12 below matches the bottom surface of the corresponding mold unit 201, thus making it suitable for immersion molds 200 of different shapes and effectively improving the versatility of the support mechanism 10.
[0074] In some embodiments of the present invention, the shape of the support plate 13 is adapted to the shape of the corresponding mold unit 201, so that the support plate 13 fits snugly against the corresponding mold unit 201 during assembly, avoiding indentations on the mold unit 201 caused by shape mismatch. Furthermore, the full contact surface support of the support plate 13 can suppress vibration and displacement of the mold unit 201, reduce the risk of deformation of the mold unit 201, optimize stress distribution, reduce low-weld deformation and residual stress, thereby improving welding quality and reducing the welding defect rate.
[0075] According to some embodiments of the present invention, such as Figure 4 and Figure 5As shown, the assembly device 100 may further include: a limiting mechanism 30, which forms a limiting space 31 for assembling the assembly flanges 203 of two adjacent mold units 201 that are assembled together, so that the limiting mechanism 30 restricts the assembly flanges 203 of the two adjacent mold units 201 from moving away from each other, and the limiting mechanism 30 is fixed to at least one support plate 13.
[0076] The limiting mechanism 30 forms a limiting space 31. After the assembly flanges 203 of two adjacent mold units 201 that are assembled together are welded, the limiting space 31 is used to assemble the assembly flanges 203 of the two adjacent mold units 201 that are assembled together, so that the limiting mechanism 30 restricts the assembly flanges 203 of the two adjacent mold units 201 from moving away from each other. This is used to reduce the instability of the weld of the corresponding mold unit 201 during vacuum pressure impregnation and to prevent the weld of the assembly flange 203 from being damaged due to the increase of internal pressure.
[0077] The limiting mechanism 30 is fixed to at least one support plate 13. The limiting mechanism 30 can be fixed to one support plate 13, or it can be fixed to multiple support plates 13 simultaneously, which can be reasonably set according to the actual situation. The limiting mechanism 30 is fixed to at least one support plate 13, which can fix the position of the limiting mechanism 30 so that the limiting mechanism 30 can stably limit the assembly flanges 203 of two adjacent mold units 201 that are assembled together, and can also prevent the limiting mechanism 30 from being pried open by the weld of the assembly flange 203 and falling off the assembly flange 203.
[0078] According to some embodiments of the present invention, such as Figure 4 and Figure 5 As shown, the limiting mechanism 30 includes: a fixed plate 32, a first clamping plate 33 and a second clamping plate 34. The first clamping plate 33 and the second clamping plate 34 are opposite to each other and spaced apart. The first clamping plate 33 and the second clamping plate 34 are parallel to each other. The first clamping plate 33 and the second clamping plate 34 are located on the same side of the fixed plate 32 and fixed to the fixed plate 32, so that the fixed plate 32, the first clamping plate 33 and the second clamping plate 34 together define the limiting space 31.
[0079] The fixing plate 32, the first clamping plate 33, and the second clamping plate 34 can all be made of steel plate. The first clamping plate 33 and the second clamping plate 34 are opposite to each other and spaced apart. The first clamping plate 33 and the second clamping plate 34 are parallel to each other. The first clamping plate 33 and the second clamping plate 34 are located on the same side of the fixing plate 32 and are fixed to the fixing plate 32. In some embodiments of the present invention, the first clamping plate 33, the second clamping plate 34 and the fixing plate 32 can be integrally formed, or the first clamping plate 33, the second clamping plate 34 and the fixing plate 32 can be fixedly connected by welding or bolts, as long as the first clamping plate 33 and the second clamping plate 34 are located on the same side of the fixing plate 32 and are fixed to the fixing plate 32.
[0080] The fixing plate 32, the first clamping plate 33, and the second clamping plate 34 together define the limiting space 31. The dimensions of the first clamping plate 33 and the second clamping plate 34 are adapted to the dimensions of the corresponding assembly flange 203 so as to limit the entire assembly flange 203 within the limiting space 31. This can further reduce the instability of the weld of the corresponding mold unit 201 during vacuum pressure impregnation and prevent the weld of the assembly flange 203 from being damaged due to increased internal pressure, thereby effectively improving the reliability and service life of the impregnation mold 200.
[0081] According to some embodiments of the present invention, such as Figure 4 and Figure 5 As shown, the limiting mechanism 30 may further include: a fixing block 35, which is fixed to at least one of the fixing plate 32, the first clamping plate 33, and the second clamping plate 34, and is fixed to the corresponding support plate 13 by a second fastener.
[0082] The fixing block 35 is fixed to at least one of the fixing plate 32, the first clamping plate 33, and the second clamping plate 34. In some embodiments of the present invention, the fixing block 35 may be fixed to the fixing plate 32, or the fixing block 35 may be fixed to the first clamping plate 33, or the fixing block 35 may be fixed to the second clamping plate 34, or the fixing block 35 may be fixed to two of the fixing plate 32, the first clamping plate 33, and the second clamping plate 34, or the fixing block 35 may be fixedly connected to all of the fixing plate 32, the first clamping plate 33, and the second clamping plate 34. The fixing block 35 can be reasonably set according to the actual situation.
[0083] After the limiting mechanism 30 is assembled with the corresponding assembly flange 203, the fixing block 35 is fixed to the corresponding support plate 13 by the second fastener to fix the position of the limiting mechanism 30, so that the limiting mechanism 30 can stably limit the assembly flanges 203 of the two adjacent mold units 201 that are assembled together, and can also prevent the limiting mechanism 30 from being pried open by the weld of the assembly flange 203 and falling off the assembly flange 203.
[0084] Furthermore, the specific process flow of the present invention can be as follows:
[0085] (1) such as Figure 6 As shown, the mold module is cut and the assembly flange 203 is made. The length of the assembly flange 203 can be reasonably set according to the actual situation. As a specific embodiment of the present invention, the length of the assembly flange 203 can be 30mm.
[0086] (2) such as Figure 1 As shown, the immersion mold 200, composed of each mold unit 201, is hoisted onto the work platform as a whole.
[0087] (3) such as Figure 2 As shown, the support mechanism 10 is assembled with the immersion mold 200, each mold unit 201 is adjusted to the precise position, and the position where the assembly flange 203 needs to be welded is left.
[0088] (4) The position of the assembly flange 203 is repaired. When there is a gap between any two adjacent mold units 201 that are assembled together, thin stainless steel sheets are used to fill the gap and then spot welded. The spot welding spacing is 50mm and the number is as large as possible. After spot welding, DC pulse argon arc welding is used for self-fusion (without wire). The welding is symmetrical. The welding sequence is: vertical weld on the outer side (continuous welding from bottom to top), vertical weld on the inner side (continuous welding from bottom to top), upper horizontal weld, lower horizontal weld, and T-weld.
[0089] (5) After welding is completed, non-destructive testing (visual inspection, penetration testing, leak detection, pressure test) shall be carried out.
[0090] (6) For example Figure 3 As shown, the limiting mechanism 30 is assembled with the assembly flange 203 and the support plate 13.
[0091] (7) The immersion mold 200 needs to completely enclose the magnet coil and perform vacuum pressure immersion.
[0092] This increases the structural strength of the impregnation mold 200 and widens the gap between the weld and the magnet coil, solving problems such as back-side oxidation of the weld and the impact of high welding temperatures on the magnet coil. By setting up a support mechanism 10 to support the corresponding mold unit 201, the position of the mold unit 201 can be adjusted, ensuring accurate welding position and improving welding quality and precision, effectively reducing the risk of welding deformation and failure. Furthermore, the limiting mechanism 30 restricts the movement of the assembly flanges 203 of adjacent mold units 201 away from each other, reducing weld instability during vacuum pressure impregnation and preventing damage to the assembly flanges 203 due to increased internal pressure. This ensures the assembly flanges 203 remain functional under prolonged and complex operating conditions, and the support mechanism 10 and limiting mechanism 30 are easily disassembled and reusable.
