[0026] The following is a complete description of the embodiments of the present invention in conjunction with the accompanying drawings.

[0027] like Figure 1 、 Figures 3 to 5As shown, an embodiment of a coil winding device for electromagnetic forming according to the present invention comprises a base plate 9, a slide 7, a first stepper motor, a second stepper motor 8, a reducer 10, a three-jaw chuck 5, a side-mounted base 1, a wire feed mechanism 6, a winding rod 2, a male winding sleeve 3, a female winding sleeve 4, and a plurality of jacks 11. The first stepper motor is connected to the slide 7 and mounted on the base plate 9. The second stepper motor 8, the reducer 10, and the three-jaw chuck 5 are sequentially connected and mounted on the slide 7. The side-mounted base 1 is mounted on the base plate 9 via the jack 11 and cooperates with the three-jaw chuck 5. The wire feed mechanism 6 is mounted on the base plate 9 via the jack 11 and cooperates with the side-mounted base 1. The winding rod 2 is clamped on the three-jaw chuck 5, the male winding sleeve 3 is fixed to the winding rod, and the female winding sleeve 4 is mounted in the side-mounted base 1. The base plate 9 is a rectangular iron base plate for mounting components. The jack 11 adopts a mold screw jack to adjust the height and provide support.

[0028] like Figures 3 to 5 As shown, the winding rod 2, winding sleeve-male 3, and winding sleeve-female 4 are prior art and correspond to the winding rod, winding sleeve-male, and winding sleeve-female in existing coil winding devices for electromagnetic forming. The winding rod 2 is used to support and guide the winding process of the copper wire, ensuring that the copper wire is wound according to the set path. The male end of the winding sleeve-male 3 is used to press the cylinder and other special mechanical parts. The male end of the winding sleeve-male 3 is used to compress and fix the copper wire to ensure the stability of the copper wire during the winding process. The winding sleeve-female 4 is used to compress and fix the copper wire to ensure the stability of the copper wire during the winding process.

[0029] like Figure 2 As shown, the side-mounted base 1 consists of a rectangular base body with a transverse mounting hole. Mounting bosses are located on both sides of the bottom of the rectangular base body, and a clearance groove is formed on the top surface, which communicates with the transverse mounting hole. The upper side of the base body has two locking threaded holes for winding the sleeve-nut 4. These two locking threaded holes are arranged side by side. Side-mounted base 1 is used to mount and secure mechanical components, ensuring the stability of the entire system.

[0030] like Figure 6 As shown, the three-jaw chuck 5 is a conventional three-jaw chuck, which is connected to the reducer 10 for stabilizing and fixing the coil. The three-jaw chuck 5 is used to compress and fix the winding rod 2 to ensure the stability of the winding rod during the winding process.

[0031] like Figure 7 As shown, the wire feed mechanism 6 is a dual-wire, side-by-side, horizontal wire feed mechanism. It consists of a base plate, a mounting riser, and a wire feed pulley. The mounting riser is fixed to the base plate, and the wire feed pulley is rotatably mounted on the mounting riser, arranged in two layers. The wire feed mechanism 6 is used to straighten and feed the copper wire, ensuring its linearity.

[0032] like Figure 8 As shown, slide 7 is a GX150 heavy-duty slide equipped with a 10mm lead screw. Slide 7 is equipped with a removable mounting plate, on which the second stepper motor 8, reducer 10, and three-jaw chuck 5 are mounted. The mounting plate allows for axial movement along slide 7. The first and second stepper motors 8 are 86 stepper motors, providing rotational and lateral power. Reducer 10 is an RV40 reducer, which reduces speed and increases torque. Slide 7 supports the rotating mechanism, enabling it to move perpendicular to the copper wire.

[0033] Select a spacer copper wire with a width of 1 mm (height of 6 mm) and place it in parallel with the main copper wire (width of 3 mm, height of 6 mm). Place the two copper wires in parallel on the winding rod through the wire feeding mechanism 6. Manually control the moving axis to move forward to press the copper wires on the winding rod 2. The winding sleeve-male 3 end pressing cylinder presses the copper wires in the vertical direction to ensure that the two copper wires are fixed on the winding rod 2. Manually rotate the winding rod to start winding the two copper wires. You can also start the automatic mode after the copper wires are pressed. The system controls the rotating axis to rotate 16 circles. After stopping, during the rotation process, the first stepper motor and the second stepper motor 8 perform interpolation motion, so that the moving axis moves a distance equal to the total thickness of the two copper wires (4 mm). After winding is completed, the coil is removed and placed in a muffle furnace for high-temperature annealing for half an hour to eliminate stress in the coil. After annealing, it is cooled to room temperature, and then the 1 mm thick spacer copper wire is pulled out. The final spacing of the coils should be strictly 1 mm. Use a 1 mm thick feeler gauge to check the spacing of each coil one by one to ensure that each spacing is consistent and strictly control product quality. The first stepper motor and the second stepper motor 8 are controlled by a Siemens 1212DCDCDC controller. Pulses are sent through the system to achieve synchronous movement of the rotating axis and the moving axis, ensuring precise control of each movement during the winding process.

[0034] This new device introduces spacer copper wires during the winding process and removes coil stress through high-temperature annealing, ultimately achieving coils with a strict 1mm spacing. This precise spacing control ensures the stability and consistency of the magnetic field during electromagnetic forming, effectively improving the precision and effectiveness of the electromagnetic force. Furthermore, the device's rational design and ease of operation provide a reliable solution for electromagnetic forming technology, effectively resolving issues inherent in traditional coil winding methods and significantly improving the effectiveness and quality of electromagnetic forming technology.

[0035] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Therefore, any modification, equivalent replacement, equivalent change, or modification to the above embodiment that does not depart from the content of the present invention and is based on the technical essence of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
