The limiting block 5 and the bending block 9 have the same structure, and the surfaces of the limiting block 5 and the bending block 9 can be replaced through the sleeve 11. When the surfaces of the limiting block 5 and the bending block 9 are deformed, the surfaces of the limiting block 5 and the bending block 9 can be replaced in time, thereby ensuring the bending effect of the heating wire.

[0025] Furthermore, a guide groove is provided on the surface of the disc 4, and the screw rod 7 rotates on the guide groove of the disc 4 through the output shaft of the second motor 6. The heating wire will not touch the screw rod 7 during the bending process, thereby ensuring the normal rotation of the screw rod 7 on the guide groove of the disc 4.

[0026] Furthermore, the nut 8 is square in shape, and the nut 8 slides on the guide groove of the disc 4 through the rotation of the screw rod 7. During the rotation of the disc 4, the nut 8 is driven to rotate on the processing table 1 through the screw rod 7, so that the bending block 9 on the nut 8 bends the heating wire.

[0027] Furthermore, the limit block 5 is at the center of the disk 4, the limit block 5 and the bending block 9 are on the same horizontal plane, and the bending block 9 moves linearly on the surface of the disk 4 through the nut 8.

During the rotation of the screw rod 7, the nut 8 is driven to slide on the guide groove of the disc 4. The disc 4 drives the bending block 9 to slide on the surface of the disc 4, thereby changing the relative distance between the limit block 5 and the bending block 9, making it easier to bend heating wires of different diameters and improving the quality of bending.

[0031] The bending block 9 is divided into two parts, a base column 10 and a sleeve 11. The sleeve 11 is sleeved on the base column 10. At this time, the limiting rod 12 on the sleeve 11 is inserted into the circular hole of the base column 10.
