According to an example of the present invention, Figure 1 and Figure 2 , which are the formal diagram and axial view of the present invention. The conductor is formed using the forming module assembly 2, and the styles of the various components in the forming module assembly 2 are adjusted according to the forming requirements, and the forming servo motor 205 or the feeding servo motor 303 is started to drive the conductor to form.

[0035] like Figure 1-3 As shown, the truss assembly 1 includes a crossbeam 101, a suspension frame 102, a column 103, a pre-tightening rod 104, a base 105, a feed support frame 106, and a guide support frame 107, which are used to provide support for the forming module assembly 2, the feed module assembly 3 and the guide module assembly 4 during the winding process to prevent the module assemblies from tipping over and disrupting the continuous winding of the coil; the crossbeam 101 is connected to the suspension frame 102 and the column 103 by bolts; the crossbeam 101 is connected to the pre-tightening rod 104 by bolts; the pre-tightening rod 104 is connected to the base 105 by bolts; the base 105 is pre-buried and installed on the ground. The molding module assembly 2 is connected to the suspension frame 102 through a bearing; the feeding module assembly 3 is connected to the feeding support frame 106 through bolts; the guiding module assembly 4 is connected to the guiding support frame 107 through bolts; the conductor enters the feeding module assembly 3 through the guiding module assembly 4, and enters the molding module assembly 2 driven by the feeding motor; the molding module assembly 2 and the feeding module assembly 3 are engaged by gears to make the molding module assembly 2 rotate.

[0036] like Figure 4-6 As shown, the forming module assembly 2 includes a forming mounting plate 201, a return bending wheel module 202, a roller assembly 203, a rotating assembly 204, a forming servo motor 205, a press bending wheel module 206, and a pressing electric cylinder 207. By replacing the above different forming module assemblies, the functions of return bending, press bending and rolling bending of the conductor can be realized; the installation position of the forming module assembly is set on the forming mounting plate 201 as shown in Figure 4As shown, the return wheel mold assembly is formed by combining the return wheel mold assembly 202, the rotating assembly 204, the roller assembly 203 and the pressing electric cylinder 207; the installation position of the forming module assembly is set on the forming installation plate 201 as shown in Figure 5 As shown, the bending wheel die assembly is formed by combining the rotating assembly 204, the roller assembly 203, the bending wheel die set 206 and the pressing electric cylinder 207; the installation position of the forming module assembly is set on the forming installation plate 201 as shown in Figure 6 As shown, the rolling die assembly is formed by combining the rotating assembly 204, two sets of roller assemblies 203 and the pressing electric cylinder 207; the conductor is fixed by the clamp on the bending die assembly 202 to realize the bending forming function of the conductor; the roller assembly 203 is installed on the forming mounting plate 201, and is clamped during the conductor forming process to prevent the conductor from deflecting; the rotating assembly 204 is installed at the bottom of the forming mounting plate 201 through a bearing, and the rotating assembly 204 is driven to rotate by rotating the rotating motor 307, so that the forming mounting plate 201 is rotated to a required angle; the forming servo motor 205 is installed under the forming mounting plate 201, and is used to drive the bending die assembly 202 to rotate; the bending die assembly 206 is installed on the forming mounting plate 201, and is used for conductor bending forming; the pressing electric cylinder 207 is as shown in FIG. Fig.10 As shown, it is mounted on the molded mounting plate 201, as shown Figure 5 The figure shows the bending of the conductor. The pressing electric cylinder 207 drives the pressing wheel 207-1 to do telescopic movement. The pressing wheel 207-1 pushes the conductor to produce a pressing amount. When the conductor fits the bending wheel module 206, the pressing wheel 207-1 stops moving, and the feeding module assembly 3 drives the conductor to move, thereby realizing the bending of the conductor. The pressing wheel 207-1 can also realize the rotation around the main axis of the electric cylinder. Figure 6 The figure shows the roll forming of the conductor. The principle of conductor roll forming is basically the same as that of press forming. The roll forming does not include a wheel die set. The pressing cylinder 207 pushes the conductor to produce a pressing amount. Different pressing amounts result in different conductor radii after forming. The wheel die is a groove wheel structure. The installation position is as shown in FIG. Figure 4 As shown, according to the different wheel mold radius and circumferential cross-sectional radius, bends with different bending radii and conductor sizes can be realized. The forming servo motor 205 drives the wheel mold to rotate through gear meshing, and the roller assembly 203 performs telescopic movement through the screw rod, thereby achieving the clamping function to buffer the reaction force generated during conductor forming. The rotating assembly 204 drives the forming mounting plate 201 to rotate along its long axis through the rotating motor 307, and according to the spatial angle of each bend segment of the conductor forming, the forming mounting plate 201 is rotated to the required angle to prepare for the subsequent conductor forming.

[0037] like Figure 7As shown, the feed module assembly 3 includes a feed mounting plate 301, a clamping wheel set 302, a feed servo motor 303, a length counting encoder assembly 304, a feed wheel set 305, a coder 306, and a rotary motor 307, which are used to drive the conductor to translate along its axis; the clamping wheel set 302, the feed servo motor 303, the length counting encoder assembly 304, and the feed wheel set 305 are connected to the feed mounting plate 301 by bolts; the feed mounting plate 301 is connected to the feed support frame 106 by bolts; the clamping wheel set 302 is telescopically moved by a screw rod to achieve a clamping effect on the conductor, and the feed servo motor 303 drives the feed wheel set 305 to rotate through gear meshing, so that the conductor translates along its axis. The length counting encoder assembly 304 is used to detect and record the winding length of the conductor; during the winding process, it is necessary to draw a long line in the axial direction of the conductor, draw a loop line in the axial direction of the conductor, etc. according to the different bends, so it is necessary to use a coder 306 for marking the conductor.

[0038] like Figure 8 As shown, the guide module assembly 4 includes a guide mounting plate 401, a guide rail 402, and a guide block 403, which are used to guide the conductor to move horizontally and prevent twisting during the bending process; the guide rail 402 is connected to the guide mounting plate 401 by bolts; the guide mounting plate 401 is connected to the guide support frame 107 by bolts; the guide block 403 is extended and retracted by a screw rod to clamp the conductor, which is used to guide the conductor to move horizontally and prevent twisting during the bending process. During the forward movement of the conductor, the guide block 403 moves along the guide rail 402. After moving a certain distance, the guide block 403 in front is removed and reinstalled at the back.

[0039] like Fig. 9As shown, the multi-degree-of-freedom die dropping platform 5 includes an assembly platform 501, a working platform 502, a rotating support 503, an electric cylinder 504, a bottom support 505, and an X / Y translation mechanism 506, which are used to provide a stroke and angle for coil winding and assemble the coil after forming; the assembly platform 501 is connected to the rotating support 503 by bolts; the working platform 502 is connected to the bottom support 505 by bolts; the rotating support 503, the electric cylinder 504, and the bottom support 505 are connected by bolts; the bottom support 505 is connected to the X / Y translation mechanism 506 by bolts; and the X / Y translation mechanism 506 is connected to the ground by bolts. The rotating support 503 drives the assembly platform 501 to rotate through a motor to match the coil forming trajectory. The electric cylinder 504 performs telescopic movement to change the rotation angle of the assembly platform 501. The X / Y translation mechanism 506 drives the bottom support 505 to translate in the X and Y directions through a motor. Below the device is a multi-degree-of-freedom die drop platform 5. The conductor is fixed on the assembly platform 501 through a support fixture. After the molding module assembly 2 rotates, due to the different molding postures of the conductor, the rotation support 503, the electric cylinder 504, and the X / Y translation mechanism 506 are used to adjust the positional relationship between the assembly platform 501 and the coil. Fig.11 As shown, it includes an assembly base 501-1 and a support fixture 501-2, and the assembly base 501-1 and the support fixture 501-2 are connected by bolts, wherein the support fixture is a layered structure. After the conductor is wound and formed by the forming module assembly 2, in order to avoid the shape of the coil changing due to the conductor's own gravity, it is necessary to use an assembly platform 501 to receive the conductor, install the support fixture 501-2 according to the formed part of the coil, and fix the conductor.

[0040] The forming servo motor 205 drives the forming wheel mold to rotate through gear meshing. After one turn of the outer coil is formed, it begins to be dropped onto the assembly platform 501. The formed part of the coil is fixed by the assembly support on the assembly platform 501. The fixed length of the coil increases with the forming length until the entire drop is completed.

[0041] The assembly platform 501 rotates under the action of the electric cylinder and the motor, and the X / Y translation mechanism 506 moves under the action of the motor. The multi-degree-of-freedom die-dropping platform 5 is synchronized with the conductor forming trajectory to reduce the internal stress during the conductor forming process. The center point of the multi-degree-of-freedom die-dropping platform 5 establishes a relative coordinate system, establishes different mathematical relationships according to different conductor forming methods, and uses MATLAB to simulate the conductor forming trajectory. The multi-degree-of-freedom die-dropping platform 5 is synchronized with the conductor forming trajectory to reduce the internal stress during the conductor forming process.
