The steel bar cutting device with a protective structure for construction engineering is provided with a protective plate, a threaded rod 1, a threaded rod 2, an anti-skid belt 1, a movable sleeve 1, a motor 2 and a movable sleeve 2. When the steel bar needs to be cut, the threaded rod 2 is driven by the motor 2 to rotate. Since the threaded rod 2 is connected to the threaded rod 1 through the anti-skid belt 1, the threaded rod 1 and the threaded rod 2 can rotate synchronously. The movable sleeve 1 and the movable sleeve 2 on both sides of the protective plate will move on the surfaces of the threaded rod 2 and the threaded rod 1. The protective plate will overlap the surface of the steel bar when moving. The cutting device can achieve a height adjustment function of the protective plate on the workbench through the cooperation between the threaded rod 1, the threaded rod 2 and the anti-skid belt 1, which is convenient for protecting the part where the steel bar is cut and avoiding the phenomenon of sparks flying during the cutting process, thereby effectively ensuring the adaptability of the cutting device.

[0013] 2. The steel bar cutting device with a protective structure for construction engineering can evenly cool the contact points by setting a guide groove, an arc gear and a straight gear. The external driver drives the straight gear to rotate around the driving rod. Since the straight gear and the arc gear are in a meshing state, the arc gear and the straight gear rotate synchronously, and the straight gear slides in the guide groove when rotating, enabling the turntable to drive the screw rod five to achieve the function of reciprocating rotation.

One side of the cutting tool 4 is connected to a first motor 5. A third threaded rod 15 is rotatably connected inside the limiting plate 16. The baffle 6 is lapped with the fixed plate 17, and the limiting plate 16 is lapped with the baffle 6. By providing the limiting plate 16 and the fixed plate 17, when the third threaded rod 15 is rotated, the third threaded rod 15 will drive the limiting plate 16 and the fixed plate 17 to approach each other, facilitating the positioning of steel bars of different specifications and preventing the steel bars from being misaligned during cutting;

[0022] One side of the protective plate 7 is connected to a first movable sleeve 12, and the other side of the protective plate 7 is connected to a second movable sleeve 14. An anti-slip belt 11 is externally connected to the second threaded rod 10. A second motor 13 is connected below the second threaded rod 10. A fourth threaded rod 21 and a fifth threaded rod 22 are rotatably connected inside the protective plate 7. One side of the protective plate 7 is connected to a sleeve plate 19. One end of the fifth threaded rod 22 is connected to a turntable 20. An anti-slip belt 27 is externally connected to the fourth threaded rod 21. The fourth threaded rod 21 is connected to the fifth threaded rod 22 through the anti-slip belt 27. A guide groove 28 is formed inside the turntable 20;

[0023] By providing the protective plate 7, when the fourth threaded rod 21 and the fifth threaded rod 22 are rotated, the moving block 23 will move on the surface of the fifth threaded rod 22, and the moving block 23 will slide inside the protective plate 7, enabling the protective plate 7 to play a certain auxiliary role in the movement of the moving block 23 and preventing the moving block 23 from colliding with the protective plate 7 during movement;

[0024] One side of the turntable 20 is connected to an arc-shaped gear 29. A groove 30 is formed inside the sleeve plate 19. A driving rod 31 is slidably connected inside the groove 30. One end of the driving rod 31 is connected to a spur gear 32. The spur gear 32 is slidably connected inside the guide groove 28. The spur gear 32 meshes with the arc-shaped gear 29. By providing the guide groove 28, when the spur gear 32 rotates, after the spur gear 32 contacts the arc-shaped gear 29, it will slide inside the guide groove 28, enabling the guide groove 28 to play a certain guiding role in the movement of the spur gear 32 and preventing the spur gear 32 from jamming during movement;

[0025] The outer thread of the fifth threaded rod 22 is connected to a moving block 23. A spraying head 24 is connected to the moving block 23. A hose 25 is connected to one side of the moving block 23. A water tank 26 is connected to the protective plate 7. The hose 25 is connected to the water tank 26. The second threaded rod 10 is connected to the first threaded rod 9 through a first anti-slip belt 11. The second moving sleeve 14 is threadedly connected to the outside of the first threaded rod 9. The first moving sleeve 12 is threadedly connected to the outside of the second threaded rod 10. A cutting groove 8 is formed in the protective plate 7. By providing the first anti-slip belt 11, when the second motor 13 drives the second threaded rod 10 to rotate, since the second threaded rod 10 is connected to the first threaded rod 9 through the first anti-slip belt 11, the first threaded rod 9 and the second threaded rod 10 can achieve the function of synchronous rotation, and the protective plate 7 can move evenly, avoiding the protective plate 7 from tilting during movement.

[0026] The working principle of the present utility model is as follows:

[0027] When the cutting device cuts the steel bar, the steel bar can be placed above the workbench 2. The third threaded rod 15 drives the limiting plate 16 to move. After the limiting plate 16 moves, it will limit the steel bar through the fixing plate 17. When the steel bar needs to be cut, the second motor 13 drives the second threaded rod 10 to rotate. Since the second threaded rod 10 is connected to the first threaded rod 9 through the first anti-slip belt 11, the first threaded rod 9 and the second threaded rod 10 can rotate synchronously. The first moving sleeve 12 and the second moving sleeve 14 on both sides of the protective plate 7 will move on the surfaces of the second threaded rod 10 and the first threaded rod 9. When the protective plate 7 moves, it will overlap on the surface of the steel bar. When the steel bar is cut by the cutting tool 4 in the cutting disc 3, the external driver drives the spur gear 32 to rotate around the driving rod 31. Since the spur gear 32 is in meshing with the arc gear 29, the arc gear 29 and the spur gear 32 rotate synchronously, and the spur gear 32 will slide in the guide groove 28 when rotating. The turntable 20 drives the fifth threaded rod 22 to rotate when rotating, and the fourth threaded rod 21 will rotate with the fifth threaded rod 22 through the second anti-slip belt 27. The moving block 23 will reciprocate in the protective plate 7. The water tank 26 transports the coolant to the spraying head 24 through the hose 25 by the built-in water pump. The spraying head 24 will cool the cutting part when moving.
