[0028] A heating device 10 is installed at the input end of the wire feeding mechanism. An opening for accommodating the heating device 10 is provided on one side of the shielding device 19 to facilitate the sliding installation of the shielding device 19. Heating disks 101 are installed on the top and bottom of the heating device 10, and a heating tube is installed inside the heating disk 101.

[0029] The wire feeding mechanism includes a lower wire feeding wheel 9, an upper wire feeding wheel 12 and a first driving device, the first driving device is installed inside the machine body 1, and at least two groups of lower wire feeding wheels 9 and upper wire feeding wheels 12 are provided, and at least two groups of lower wire feeding wheels 9 and upper wire feeding wheels 12 are provided correspondingly;

The two driven gears 121 are fixedly connected to the lower wire feeding wheel 9 and the upper wire feeding wheel 12, respectively.

[0031] In view of the above, when using the bending machine produced by the spring, the slider 193 inside the shielding device 19 is slid into the slide grooves 11 on both sides of the machine body 1 to complete the installation of the shielding device 19, making the bending machine safer to use and having a dust-proof effect.

At this time, the third motor 18 and the third cylinder 17 are started by the control device 5, and the third motor 18 drives the rotating rod 181 to rotate, so that the wire can be bent in a circle on the rotating rod 181 to form a spring. At the same time, the rotating rod 181 at one end of the third motor 18 is driven by the third cylinder 17 to extend outward, so that the wire can always be bent on the rotating rod 181, thereby completing the bending of the spring.

Since the cutter 21 is eccentrically arranged, the eccentric wheel 22 can drive the cutter 21 to slide up and down on the slide 2.
