[0036] A method for using a large-scale cutting machine for processing high-strength steel sections, the method comprising the following steps: Step 1: By turning the knob 56, the threaded rod 55 is driven to rotate, and the movable plate 54 is driven to clamp and fix the steel on the support frame 53. The movable plate 54 is separated from the push block 61 during the movement, and the side baffle 4 can be closed under the elastic action of the return spring 63 and the connecting spring 66; Step 2: The reciprocating ram 9 drives the supporting block 70 to move by connecting the bent rod 13, and the bristles 74 push the residues produced by cutting on the surface of the steel section, and the residues are pushed into the slag collecting box 12 for easy collection; Step three: When the supporting connecting block 70 moves to the bottom of the first fixed plate 77, the bristles 74 can be shaken up and down with the cooperation of the smooth protrusion 75 and the matching protrusion 78. At the same time, the gas in the fixed cavity block 79 can enter the connecting flat tube 71 through the elastic connecting tube 716, and then be sprayed out through the jet flat tube 72. The bristles 74 are cleaned by shaking and jetting, thereby achieving self-cleaning of the bristles 74.

[0037] In actual use, before processing, such as Figure 6As shown, the side baffle 4 is in an open state, which is convenient for placing the steel section, the return spring 63 is in a compressed state, and the connecting spring 66 is in a stretched state, so that the steel section is placed on the support frame 53, and by turning the knob 56, the threaded rod 55 is driven to rotate, driving the movable plate 54 to clamp and fix the steel section block on the support frame 53, and the movable plate 54 is disengaged from the pushing block 61 during the movement, and under the elastic action of the return spring 63 and the connecting spring 66, the pushing block 61 is driven to move, and the pushing block 61 drives the sliding plate 62 to slide on the partition panel 3, and the sliding plate 62 drives the connecting long plate 64 to approach the partition panel 3, drives the sliding connecting plate 65 to slide on the fixed block 610, and the sliding connecting plate 65 drives the first tooth plate 67 to slide, and the first tooth plate 67 drives the first gear 68 to rotate, thereby realizing that the side baffle 4 is close to the partition panel 3, and the side baffle 4 is closed, as shown in FIG. Figure 4 As shown, the steel section is surrounded by the baffle plate 3 and the side baffle plate 4 to prevent residue from splashing during processing. When the processing is completed, the movable plate 54 is reset, and the movable plate 54 can drive the pushing block 61 and the sliding plate 62 to move, so as to realize the opening of the side baffle plate 4, and the convenience is improved. The reciprocating slide 9 drives the supporting connecting block 70 to move through the connecting bent rod 13, and pushes the residue generated on the surface of the steel section due to cutting through the bristles 74, and the residue is pushed into the slag collecting box 12 for easy collection.

When the smooth protrusion 75 is in contact with the matching protrusion 78, the smooth protrusion 75 is pressed downward. When the engagement protrusion 78 is disengaged, under the elastic action of the first spring 76, the connecting flat tube 71, the jet flat tube 72, the movable support plate 73 and the bristles 74 can move downward, thereby realizing the up and down shaking of the bristles 74. At the same time, the first baffle 717 limits the movement of the connecting baffle 710, and the sliding column 711 drives the piston plate 713 to squeeze the gas inside the fixed cavity block 79 through the air outlet connecting pipe 715. The gas then enters the connecting flat tube 71 through the elastic connecting pipe 716, and is then ejected through the jet flat tube 72. The bristles 74 are cleaned by shaking and jetting, thereby realizing self-cleaning of the bristles 74. When the connecting baffle 710 is disengaged from the first baffle 717, under the elastic action of the second spring 712, the piston plate 713 is driven to reset, thereby realizing the external gas entering the fixed cavity block 79 through the air inlet connecting pipe 714.
