A lifting plate 14 is arranged above the fixed plate 8. The front side of the top of the lifting plate 14 is provided with two slide grooves 15. The two slide grooves 15 are arranged on the front side of the top of the lifting plate 14. 15 are all slidably connected with a slider 16 inside, a connecting rod 18 is arranged between the slider 16 and the mounting plate 27, a connecting rod 17 is arranged between the slider 10 and the lifting plate 14, the bottom of the mounting plate 11 is slidably connected to the top of the fixed plate 8, one end of the connecting rod 17 is rotatably connected to the bottom of the lifting plate 14, and the other end of the connecting rod 17 is rotatably connected to the top of the mounting plate 11, one end of the connecting rod 18 is rotatably connected to the bottom of the slider 16, and the other end of the connecting rod 18 is rotatably connected to the top of the mounting plate 27.

[0033] Specifically, two sliders 10 are arranged on the top of the fixed plate 8 to slide inside the slide groove 9, which ensures the stability of the slider 10 during movement and provides reliable support for its subsequent lifting action. The mounting plate 11 is connected to the threaded rod 13 and moves with the rotation of the threaded rod 13. It drives the lifting plate 14 to move in the vertical direction and is a key component for realizing the steel lifting function. The motor 12 provides power for the threaded rod 13 to rotate. By controlling the forward and reverse rotation of the motor, the lifting action of the lifting plate 14 can be realized. The rod 13 is connected to the mounting plate 11 by threads.

At this time, the starting motor 21 drives the worm 22 to rotate. The rotation of the worm 22 drives the two worm wheels 23 meshing with it to rotate. The rotation of the worm wheel 23 drives the connecting plate 25 to rotate, and drives the clamping claw 26 to clamp the steel with the cooperation of the connecting plate 24. At this time, the steel needs to be lifted to a suitable processing position, and the starting motor 12 drives the threaded rod 13 to rotate. The rotation of the threaded rod 13 drives the mounting plate 11 to move to the rear side, so that the slider 10 slides in the slide groove 9, and at the same time pushes the connecting rod 17 and the connecting rod 2 18 upward, which will cause the lifting plate 14 to move upward. At this time, the connecting rod 2 18 is on The slider 16 will slide in the slide groove 15, and the driving motor 12 will be stopped when it reaches the appropriate position. At this time, the steel can be processed. After the processing is completed, the motor 12 is started to drive the threaded rod 13 to rotate, and at the same time drive the mounting plate 11 to move forward, so that the slider 10 slides in the slide groove 9 and returns to the original position, and at the same time pushes the connecting rod 17 and the connecting rod 2 18 downward, so that the lifting plate 14 moves downward. At this time, the slider 16 on the connecting rod 2 18 will slide in the slide groove 15 and return to the original position until the lifting plate 14 returns to the original position and stops starting the motor 12. At this time, the starting motor 21 drives the worm 22 to rotate, and at the same time drives the two worm wheels 23 to rotate, and then drives the clamping claw 26 to loosen through the rotation of the connecting plate 25, and starts the conveyor belt 2 3 to transport the processed steel to the right conveyor belt 2 to complete the automatic loading and unloading.
