A two-folding plug 405, a three-folding plug 406 and a four-folding plug 407 are respectively provided on the folding line seat 401 through the through slot 6 to the front end, the lower end and the rear end. The front end of the two-folding module 402 is provided with a two-fold bending portion 4021 corresponding to the loading module 2, and the rear end is connected to the lever of the two-folding hydraulic telescopic cylinder 4023 through a two-folding connecting plate 4022. The cylinder seat of the two-folding hydraulic telescopic cylinder 4023 is fixed on the base 7. The side of the three-folding module 403 corresponds to the loading module 2.

[0021] Specifically, the two-fold bending portion 4021 includes two bending strips extending outward horizontally, the two bending strips are arranged corresponding to the folding groove 204 and the head ends are provided with an L-shaped notch 40211, and a first limiting groove 40212 matching the first limiting strip 212 is formed between the two bending strips. The four-fold bending portion 4041 extends outward horizontally and a second limiting groove 40411 is provided in the middle corresponding to the second limiting strip 213. Since the outer end surface of the first limiting strip 212 is flush with the loading female seat 201 or the loading male seat 202, after the double-fold module 402 is inserted into place, the first limiting groove 10212 is engaged with the first limiting strip 212, and the double-fold bending portion 4021 is pushed inward through the folding groove 204 on the side of the inductor placement cavity 203, and the double-fold bending portion 4021 is provided with an L-shaped notch 4022 near the end, which is conducive to the lower end of the double-fold bending portion 4021 continuing to press the coil to the bottom end of the magnetic core, ensuring that the coil is close to the magnetic core after the double fold, and the horizontal upper body faces the other end. The outer end face of the second limit strip 213 is located in the loading male seat 202 or the loading female seat 201, and there is a gap with the side end face of the loading module 2. After the four-fold bending portion 4041 of the four-fold module 404 is inserted, the coil is bent along the top surface of the magnetic core along the fold line grooves 204 on both sides of the inductor placement cavity 203. At this time, the length of the coil of the fourth fold is smaller and the bending is shallower. Therefore, the U-shaped four-fold bending portion 4041 cooperates with the shorter second limit strip 213 to ensure that the bending is in place, which not only ensures the close contact between the coil and the magnetic core, but also avoids damage to the magnetic core behind the coil due to excessive operation.

[0022] Working principle: manually place the magnetic core-coil combination on the loading female seat 201 of the loading module 2, so that the magnetic core falls into the inductor placement cavity 203, and the coil extends toward the front side of the loading module (that is, one side of the first limit strip); align the loading male seat 202 with the loading female seat 201, close them to obtain the loading module 2, and then place the loading module into the through slot 6 of the feeding module 1, and press the start button. The lever of the pushing cylinder 9 extends out to push the loading module 2 to the tangent module 3, and the lever of the one-fold hydraulic telescopic cylinder extends downward to drive the one-fold module 308 and the tangent module 309 to move. The tangent module 309 cuts off the excess part of the coil, and at the same time, the one-fold module is inserted into the front end of the loading module 2 to push the coil to bend downward. When the pushing cylinder 9 completes the action, a new loading module 2 is placed into the feeding module 1, and the pushing cylinder 9 pushes the second loading module 2 to the right, repeating the previous step. At this time, the first loading module 2 enters the through slot 6 of the folding module 4, and the two-fold hydraulic telescopic cylinder, the three-fold hydraulic telescopic cylinder and the four-fold hydraulic telescopic cylinder act in turn to complete the bending of the magnetic core coil. With the pushing of the third loading module 2, the first loading module 2 is pushed to the unloading station to obtain the bent product.
