[0056] The cutting device for steel beams for building construction may also include any other suitable components, see Figure 1 As shown, in a specific embodiment of the present invention, the cutting device for steel beams for house construction further includes a support leg 8, the support leg 8 is vertically arranged, the workbench 1 is arranged on the support leg 8, the number of the support legs 8 is multiple, and the multiple support legs 8 are horizontally spaced apart from each other.

[0057] The number of the supporting legs 8 can be determined as needed. In a specific embodiment of the present invention, the number of the supporting legs 8 is 4, and the 4 supporting legs 8 are distributed at the 4 corners of a rectangle.

[0058] When in use, the steel beam for house construction is transported to the right to the top surface of the workbench 1 by the steel beam conveying mechanism 6. When the steel beam moves to the right, it will contact the grinding roller 520, thereby pushing the grinding roller 520 upward. The upward movement of the grinding roller 520 will drive the rotating rod 519 to move upward. The upward movement of the rotating rod 519 will drive the front connecting plate 517 and the rear connecting plate 518 to move upward. The upward movement of the front connecting plate 517 and the rear connecting plate 518 will drive the front connecting block 515 and the rear connecting block 516 to move upward. The upward movement of the front connecting block 515 and the rear connecting block 516 will compress the front elastic telescopic rod 513 and the rear elastic telescopic rod 514. When the steel beam is completely placed on the top surface of the workbench 1, the front elastic telescopic rod 513 and the rear elastic telescopic rod 514 will use their own elastic force to press the grinding roller 520 on the steel beam, ensuring that the steel beam maintains a stable position during the cutting process and preventing the cutting line from being offset or inaccurate due to vibration or movement of the steel beam.

[0059] By driving the cutting drive device 21 to move forward and backward through the forward and backward moving mechanism 3, the forward and backward position of the cutting drive device 21 can be adjusted. By driving the forward and backward moving mechanism 3 to move left and right through the left and right moving mechanism 4, the left and right position of the forward and backward moving mechanism 3 can be adjusted, thereby adjusting the position of the cutting wheel 22 front and back and left and right. The cutting drive device 21 can drive the cutting wheel 22 to rotate in the forward and backward direction to cut the steel beam.

[0060] During cutting, burrs may be generated at the cut of the steel beam, thereby affecting the use of the steel beam. Therefore, the rotating rod 519 is driven to rotate in the front-to-back direction by the rotating rod driving device 521. The rotation of the rotating rod 519 in the front-to-back direction will drive the grinding roller 520 to rotate in the front-to-back direction. The rotation of the grinding roller 520 in the front-to-back direction will grind the burrs generated at the cut of the steel beam, thereby ensuring the flatness of the steel beam.

[0061] When the cooling mechanism 7 is present, the coolant in the liquid storage tank 711 is transported to the fixed pipe 712 through the liquid delivery device 715, and then sprayed from the nozzle 714 to the cutting area, so as to effectively reduce the temperature during the cutting process and prevent the steel from overheating. When the cooling mechanism 7 also includes a front fixed rod 717, a rear fixed rod 718, a moving rod 719, a blocking rod 720, a connecting rod 721, a contact rod 722 and a track wheel 723, and the rotating rod driving device 521 includes a driving motor 522, a rotating shaft 523, a first rotating wheel 524, a second rotating wheel 525 and a crawler 526, the rotating shaft 523 is driven by the driving motor 522 to rotate in the front-to-back direction. The rotation of the rotating shaft 523 in the front-to-back direction will drive the first rotating wheel 524 to rotate in the front-to-back direction. The rotation of the first rotating wheel 524 in the front-to-back direction will drive the second rotating wheel 525 to rotate in the front-to-back direction through the crawler 526. Rotation, the second rotating wheel 525 rotating in the front-to-back direction will drive the rotating rod 519 to rotate in the front-to-back direction; in addition, the rotation of the rotating shaft 523 in the front-to-back direction will also drive the track wheel 723 to rotate in the front-to-back direction, and the spiral groove track 724 can make the contact rod 722 move back and forth, and the front-to-back movement of the contact rod 722 will drive the connecting rod 721 to move back and forth, and the front-to-back movement of the connecting rod 721 will drive the moving rod 719 to move back and forth, and the front-to-back movement of the moving rod 719 will drive the blocking rod 720 to move back and forth, and the back-to-back movement of the blocking rod 720 can spray the coolant evenly on the surface of the steel beam, thereby reducing the overall temperature of the steel beam.
