The second guide rod 6 One end of the second guide rod 60 is welded and fixed on the movable plate 620520, and the other end of the second guide rod 660 passes through the second fixed plate 650. The two second springs 670 correspond to the two second guide rods 660 one by one. The second springs 670 are sleeved on the corresponding outer walls of the second guide rods 660.

[0044] When in use, the steel wire gradually enters the positioning block 210 of the positioning assembly until the end of the steel wire abuts against the baffle 220, and the length of the steel wire extending out of the positioning hole 211 is the length of the hook of the anti-slip device;

[0045] The motor 700 is started, and the motor 700 drives the first rotating shaft 310 to rotate through the transmission mechanism. The first cam 370 is rotated by the first rotating shaft 310, and the first cam 370 abuts against the side wall of the bending seat 340. The bending seat 340 moves toward the direction of the steel wire.

After the groove 341 of the bending seat 340 cooperates with the upper side wall of the bending mold 300, the steel wire is pressed to form a shape consistent with the head of the anti-slip device hook and becomes a semi-finished anti-slip device hook. At this time, the semi-finished anti-slip device hook is hung on the bending mold 300, and the state of the semi-finished anti-slip device hook is a vertical state.

[0046] The new uncut steel wire continues to extend from the positioning hole 211 of the positioning block 210, squeezing the anti-slip device hook semi-finished product on the bending mold 300 onto the arc-shaped guide rod 410 of the guide assembly. The anti-slip device hook semi-finished product slides downward along the direction of the arc-shaped guide rod 410 and swings with the bending arc of the arc-shaped guide rod 410 until it falls into the guide hole 421 of the guide seat 420. At this time, the anti-slip device hook semi-finished product is in a horizontal state.

[0047] The semi-finished anti-slip device hook falls from the guide hole 421 of the guide seat 420 to the static plate 510 of the thread rolling assembly, and the motor 700 drives the second rotating shaft 630 of the pushing assembly to rotate through the transmission mechanism. The second cam 640 is rotated by the second rotating shaft 630, and the second cam 640 abuts against the side wall of the movable plate 620520. The push rod 610 moves the semi-finished anti-slip device hook toward the thread rolling assembly, and the light rod part of the semi-finished anti-slip device hook falls into the thread rolling channel 560 of the thread rolling assembly. The driving machine 530 drives the movable plate 520 to reciprocate on the running track 550 through the crank slider mechanism 540. The movable plate 520 cooperates with the static plate 510 to realize the thread rolling operation of the light rod part of the semi-finished anti-slip device hook, and after the thread rolling operation, it becomes a finished anti-slip device hook.

[0048] The above is only one embodiment of the present invention. It should be pointed out that a person skilled in the art can make several modifications and improvements without departing from the principle of the present invention, and these should also be regarded as belonging to the protection scope of the present invention.
