A connecting plate 10 is fixedly connected to the front side of the mounting plate 6 and located at the upper and lower sides of the motor 7. Through the arrangement of the motor 7, gear 8 and other structures, the tooth plate 4 can be driven to move, thereby driving the electromagnetic suction cup 5 to move, and finally driving the square railing 3 to move intermittently.

[0025] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 The end surface of each connecting plate 10 close to the rotating column 9 is fixedly connected to a limiting block 11, and the limiting block 11 is in contact with the rotating column 9. By setting the limiting block 11, the rotating column 9 can be rotationally limited. A fixed block 12 is fixedly connected to the right side of the upper end of the workbench 1, and a guide plate 13 is slidably connected to the inner wall of the fixed block 12. The guide plate 13 is fixedly connected to the tooth plate 4. By setting the guide plate 13, the tooth plate 4 can be moved and guided.

[0026] See also Figure 1 , Figure 2 , Figure 3 , Figure 5The horizontal part of the mounting frame 101 is fixedly installed with a hydraulic cylinder 14, and the telescopic end of the hydraulic cylinder 14 is slidably connected to the horizontal part of the mounting frame 101. The telescopic end of the hydraulic cylinder 14 is fixedly connected with a movable plate 15, and the movable plate 15 is slidably connected to the vertical part of the mounting frame 101. The lower end of the movable plate 15 is fixedly connected with a punch 16, and the punch 16 is slidably connected to the placement table 2. The vertical part of the mounting frame 101 is provided with a card slot 17, and the card slot 17 is provided with a plurality of card slots 17. The plurality of card slots 17 are evenly distributed on the vertical part of the mounting frame 101. Through the provision of the card slot 17, it is convenient to cooperate with the card block 18 for card connection and use. The movable plate 15 is internally slidably connected with a block 18, and the block 18 is slidably connected to the slot 17. The upper and lower sides of the block 18 are fixedly connected with slide plates 19, and each slide plate 19 is slidably connected to the movable plate 15. A spring 20 is welded to the end face of the block 18 away from the slot 17, and the other end of the spring 20 is welded to the movable plate 15. The punch 16 can be driven to move through the telescopic action of the hydraulic cylinder 14, and then the square railing 3 can be punched. Under the action of the slot 17, the block 18 and other structures, the movable plate 15 can be limited, and then the position of the punch 16 can be finely controlled.

[0027] The specific implementation process of the utility model is as follows: when the railing quick punching device needs to be used, the square railing 3 is passed through the placement platform 2, and the square railing 3 is brought into contact with the electromagnetic suction cup 5. Under the action of the electromagnetic suction cup 5, the square railing 3 can be magnetically fixed, and the motor 7 is started to drive the output shaft to rotate. When the motor 7 drives the output shaft to rotate, the rotating column 9 can be driven to rotate, so that the rotating column 9 rotates along the inner wall of the limit block 11, so as to ensure the stable rotation of the output shaft of the motor 7 and avoid the shaking and offset problems of the output shaft of the motor 7.

[0028] When the motor 7 drives the output shaft to rotate, the gear 8 can be driven to rotate, and in a meshing relationship, the gear plate 4 can be driven to move. When the gear plate 4 moves, the guide plate 13 can be driven to slide along the inner wall of the fixed block 12 to ensure the stable movement of the gear plate 4. When the gear plate 4 moves, the electromagnetic suction cup 5 can be driven to move, thereby driving the square railing 3 to move intermittently, which is convenient for subsequent rapid automatic punching processing;

[0029] The hydraulic cylinder 14 is started to drive the telescopic end to move, so as to drive the moving plate 15 to move, and then drive the punch 16 to move stably, and finally the punch 16 contacts the square railing 3 to punch the square railing 3. In this process, the inner wall of the slot 17 squeezes the block 18, and the block 18 pushes the slide plate 19 to move, and the spring 20 is deformed, and finally the block 18 is separated from the slot 17. Under the action of force, the block 18 slides along the vertical surface of the mounting frame 101. When the block 18 slides into the next slot 17, the spring 20 restores its deformation to push the block 18 to insert into the slot 17, limit the moving plate 15, and then perform fine processing on the punch 16 to avoid the problem of unnecessary impact damage to the punch 16.
