[0020] Figure 1 The schematic diagram of a shaping tooling (including a pressing plate) for the propulsion coil of a maglev ground module according to an embodiment of the present invention is shown;

[0021] Figure 2 The schematic diagram of a shaping tooling (excluding the pressing plate) for the propulsion coil of a maglev ground module according to an embodiment of the present invention is shown.

[0022] As Figure 1 and 2 As shown, an embodiment of the present invention provides a shaping tooling for the propulsion coil of a maglev ground module. Among them, the shaping tooling includes a tooling base plate 12, a tooling pressing plate 13, a first shaping unit 14, a second shaping unit 15, a third shaping unit 16, and a transmission unit. The propulsion coil winding die (mold) 11 wound with the propulsion coil is arranged between the tooling base plate 12 and the tooling pressing plate 13. The first shaping unit 14, the second shaping unit 15, and the third shaping unit 16 are arranged on the tooling base plate 12. The first shaping unit 14 shapes the long straight side dimension of the propulsion coil at the position without lead wires under the drive of the transmission unit. The second shaping unit 15 shapes the long straight side dimension of the propulsion coil at the position with lead wires under the drive of the transmission unit. The third shaping unit 16 shapes the short straight side dimension of the propulsion coil under the drive of the transmission unit.

[0023] Through the above technical solution, the thickness dimension of the propulsion coil can be shaped by the interaction between the tooling pressing plate and the tooling bottom plate, and the straight edge dimensions of the propulsion coil can be shaped by the first shaping unit, the second shaping unit, and the third shaping unit, so as to realize the shaping of the outer dimensions of the propulsion coil, and make the electromagnetic gap between the propulsion coil and the superconducting magnet conform to the theoretically designed electromagnetic gap.

[0024] According to an embodiment of the present invention, the shaping tooling further includes a tooling support leg 111, which is arranged below the tooling bottom plate 12.

[0025] Thus, the tooling bottom plate of the shaping tooling can be lifted, making it more convenient for the shaping operation of the propulsion coil.

[0026] According to an embodiment of the present invention, the shaping tooling further includes a connecting member, and the gap between the tooling pressing plate 13 and the tooling bottom plate 12 is changed through the connecting member.

[0027] Thus, the gap between the tooling pressing plate and the tooling bottom plate can be adjusted more precisely through the connecting member, and the shaping of the thickness dimension of the propulsion coil can be better realized.

[0028] According to an embodiment of the present invention, the connecting member is a bolt.

[0029] Those skilled in the art should understand that the above bolt is merely exemplary and not used to limit the present invention.

[0030] According to an embodiment of the present invention, the tooling further includes an arc-edge limiting block 17, which is used for limiting the arc edge when shaping the propulsion coil.

[0031] Among them, the arc-edge limiting block 17 is arranged at the outer (outer ring) position of the arc section of the propulsion coil, as Figure 1 shown. For example, eight arc-edge limiting blocks 17 can be arranged.

[0032] That is, when shaping the straight edge of the propulsion coil, the arc edge of the propulsion coil can be limited at the same time to avoid the deformation of the arc edge caused by the shaping of the straight edge.

[0033] According to an embodiment of the present invention, the tooling further includes guide rail sliders 18, which are arranged below the first shaping unit 14, below the second shaping unit 15, and below the third shaping unit 16.

[0034] By setting the guide rail slider, the first shaping unit 14, the second shaping unit 15, and the third shaping unit 16 can slide better on the tooling base plate driven by the transmission unit. That is, through the interaction between the transmission unit and the guide rail slider, the first shaping unit 14, the second shaping unit 15, and the third shaping unit 16 can apply pressure to the corresponding positions of the propulsion coil to achieve the shaping of the straight sides of the coil.

[0035] According to an embodiment of the present invention, the transmission unit includes a lead screw 19 and a lead screw nut 110.

[0036] Among them, the lead screw interacts with the guide rail slider to apply pressure to the propulsion coil, and the lead screw nut is the reaction force receiving component of the lead screw (releasing the pressure applied to the propulsion coil).

[0037] According to an embodiment of the present invention, the first shaping unit 14, the second shaping unit 15, and the third shaping unit 16 are all pressure blocks.

[0038] The following describes a magnetic levitation ground module propulsion coil shaping tooling according to the present invention with reference to examples.

[0039] When the propulsion coil needs to be shaped, the wound propulsion coil together with the propulsion coil winding mold can be removed and installed on the tooling base plate of the shaping tooling; rotate the lead screw to make the pressure blocks (the first shaping unit, the second shaping unit, and the third shaping unit) apply pressure to the corresponding straight sides of the propulsion coil and shape them to the predetermined position to achieve the shaping of each straight side; after the shaping of each straight side is completed, the gap between the tooling pressing plate and the tooling base plate of the shaping tooling can be changed by bolts to achieve the shaping of the propulsion coil in the thickness direction.

[0040] In the present invention, the propulsion coil winding mold has a high positioning accuracy on the tooling base plate to ensure the coil shaping accuracy, and the gap between the arc limiting block and the propulsion coil can be adjusted according to the size of the coil.

[0041] Those skilled in the art should understand that the above shaping sequence is only exemplary and is not used to limit the present invention.

[0042] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the orientation words such as "front, back, up, down, left, right", "horizontal, vertical, perpendicular, horizontal", and "top, bottom" is usually based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description. Without contrary description, these orientation words do not indicate and imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, so it cannot be understood as a limitation on the protection scope of the present invention; the orientation words "inside, outside" refer to the inside and outside relative to the contour of each component itself.

[0043] For ease of description, spatial relative terms such as "above", "over", "on the upper surface", "upper" etc. can be used herein to describe the spatial positional relationship of a device or feature shown in the figures with other devices or features. It should be understood that the spatial relative terms are intended to encompass different orientations in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is inverted, a device described as "above" or "over" other devices or structures will then be positioned "below" or "under" the other devices or structures. Thus, the exemplary term "above" can include both the orientations of "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and corresponding interpretations of the spatial relative descriptions used herein will be made.

[0044] In addition, it should be noted that the use of terms such as "first", "second" etc. to define components is only for the convenience of differentiating the corresponding components. Without additional statements, the above terms have no special meanings, and thus should not be construed as limiting the protection scope of the present invention.

[0045] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various modifications and changes. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
