[0089] In this embodiment, the second slot is preferably an 8.5mmx61mm notch. On the fixed clamping plate 7, it extends along the length direction of the fixed clamping plate 7 to the first limiting wall, and can be freely adjusted within a distance of 30mm to 100mm. The function of the fixed clamping plate 7 is to penetrate between the head and tail turns of the coil to be processed, and can be used to ensure the consistency during the processing.
[0090] Optionally, the forming tooling further includes:
[0091] A locking buckle 11 and an unlocking handle 12;
[0092] The locking buckle 11 is arranged on the base 1 and maintains a first preset distance from the fixed seat 8;
[0093] The unlocking handle 12 is connected to the locking buckle 11;
[0094] Wherein, when the locking buckle 11 and the unlocking handle 12 are in a locked state, at least part of the rotating structure is clamped within the first preset distance; when the locking buckle 11 and the unlocking handle 12 are in an unlocked state, the rotating structure can rotate between the first limiting wall and the second limiting wall.
[0095] It should be noted that the locking buckle 11 and the unlocking handle 12 are a locking mechanism for controlling the position of the rotating structure.
[0096] In this embodiment, when the locking buckle 11 and the unlocking handle 12 are in the unlocked state, the rotating structure can rotate between the first limiting wall and the second limiting wall to complete the purpose of processing the coil to be processed; when the locking buckle 11 and the unlocking handle 12 are in the locked state, at least part of the rotating structure is locked in the first preset distance, that is, at this time, the bending handle 9 of the rotating structure can only rotate between the unlocking handle 12 and the fixed seat 8. The purpose of such a setting is not only to limit the position of the rotating structure and reduce the active range, so as to meet the purpose of processing the vertical winding coil, but also to set the first preset distance to prevent the bending handle 9 and the fixed seat 8 or the unlocking handle 12 from being set closely for a long time, affecting the service life of their components.
[0097] Specifically, the locking buckle 11 is a hinge structure, the unlocking handle 12 is connected to a hinge movable part of the hinge structure, and the angle between the unlocking handle 12 and the hinge structure is between a first angle and a second angle;
[0098] Wherein, when the unlocking handle 12 and the hinge structure are at a first angle, it is in the unlocking state, and when the unlocking handle 12 and the hinge structure are at a second angle, it is in the locking state; the second angle is greater than the first angle.
[0099] Here, the first angle is preferably 0°, and the second angle is preferably 10°.
[0100] Optionally, the locking buckle 11 is provided with a spring, and the tail of the unlocking handle 12 is tilted up under the elastic force of the spring, and after tilting up, it is 2 to 5 mm higher than the lower edge of the rotating bracket 3 .
[0101] This embodiment combines Figure 1 and Figure 3 It can be seen that when the unlocking handle 12 and the hinge structure are at 0°, it is the unlocking state, and the rotating structure can rotate between the first limiting wall and the second limiting wall; when the unlocking handle 12 and the hinge structure are at 10°, it is the locking state, and the rotating structure is controlled to be in a relative position relationship with the unlocking handle 12. When the unlocking handle 12 and the hinge structure increase from 0° to 10°, it is a process from an unlocking state to a locking state. For example, when the unlocking handle 12 and the hinge structure are at 5°, it means that it is in the process of changing from an unlocking state to a locking state. At this time, the relative position of the unlocking handle 12 and the hinge structure is in an unstable state, so the spring action of the locking buckle 11 will increase the immediacy of the change from the unlocking state to the locking state.
[0102] It should be noted that the tail of the unlocking handle 12 is tilted up under the elastic force of the spring, and after tilting up, it is 2 to 5 mm higher than the lower edge of the rotating bracket 3. The unlocking handle 12 is installed on the hinge movable part of the locking buckle 11. Pressing the unlocking handle 12 presses down the spring, and the tail of the locking buckle 11 is lower than the lower edge of the rotating bracket 3, and the rotating bracket 3 is unlocked.

[0104] A plurality of fixed cylinders 4;
[0105] The fixed cylinder 4 is disposed in the spacing space and is fixedly connected to the forming plate 2 and the base 1 respectively.
[0106] In this embodiment, the molding plate 2 is fixedly connected to the base 1 through a plurality of the fixing cylinders 4, and the fixing cylinders 4 are arranged in the spacing space, thereby ensuring the stability of the spacing space. The fixing cylinders 4 also increase the stability of the molding plate 2 and the base 1. The plurality of the fixing cylinders 4 can ensure that the molding plate 2 and the base 1 are in a relatively horizontal relationship, thereby improving the consistency during the processing.
[0107] Optionally, the forming disk 2 is an annular concave disk; the thickness of the side wall of the annular concave disk is between 10 mm and 15 mm.
[0108] It should be noted that the forming disk 2 is an annular concave disk, and the inner diameter of the cavity of the annular concave disk is preferably 210 mm, and of course the inner diameter of the cavity can be set according to actual needs. The thickness of the side wall of the annular concave disk is between 10 mm and 15 mm, which can ensure the rigidity requirements of the forming disk 2.
[0109] In another optional embodiment, the rotating structure includes:
[0110] A rotary motor and a connecting piece; the connecting piece is connected to the central shaft 5 and the rotary motor respectively.
[0111] In this embodiment, the above-mentioned rotating bracket 3, bending handle 9 and bending clamp 10 are replaced with a rotating motor and a connecting piece, and other parts are not changed. The connecting piece is connected to the central axis 5 and the rotating motor respectively, and the rotating motor can be connected to an electric control device, through which the automatic control of the rotating motor can be realized, thereby further changing the above-mentioned semi-automatic forming tool to an automatic forming tool. Of course, this embodiment and the above-mentioned embodiment can both use a highly applicable special forming tool for vertical winding coils, which can be flexibly adjusted according to different vertical winding coil forming sizes.
[0112] In summary, the forming tooling of the present invention is based on mechanical principles, has a simple structure, is flexible and portable to operate, has a short forming time, does not require auxiliary materials, and is a special forming tool for vertical winding coils with strong applicability.

[0118] Step 300, controlling the rotating structure to rotate from the position of the second limiting wall to the position of the first limiting wall;
[0119] In this embodiment, the bending handle 9 of the rotating structure can be controlled to drive the bending clamping plate 10 to rotate from the position of the second limiting wall to the position of the first limiting wall to complete one rotation operation.

Preferably, the preset time is 10 s to 15 s.
[0122] Specifically, through the above steps 100 to 400, adjust the size of the bushing 6 according to the forming size of the vertical winding coil.

After the rotating bracket 3 presses down and crosses the locking buckle 11, the unlocking handle 12 and the locking buckle 11 are in a 10° state, so that the rotating bracket 3 is locked. Release the bending handle 9 and keep it for 10 to 15 s. After the internal stress of the coil to be processed is released, press the unlocking handle 12, rotate the bending handle 9 to the position of the second limiting wall again, and retract the bending clamping plate 10 and the fixed clamping plate 7 to achieve the purpose of forming the vertical winding coil.
