[0033] The rear top of the base 1 is provided with a pushing mechanism 9 for pushing the angle steel, the pushing mechanism 9 comprises a multi-stage electric telescopic rod 902 fixedly installed at the rear of the base 1, wherein the rear of the base 1 is fixedly connected with a supporting rod, the top end of the supporting rod is fixedly connected with the bottom of the multi-stage electric telescopic rod 902, the supporting rod is used for supporting the multi-stage electric telescopic rod 902, the rear top of the base 1 movably contacts a push plate 901, the top of the push plate 901 is fixedly connected with the front end of the output shaft of the multi-stage electric telescopic rod 902, the bottom of the push plate 901 is fixedly connected with a plurality of T-shaped push blocks 903, the T-shaped push blocks 903 are located in the corresponding angle steel placing grooves 101, the multi-stage electric telescopic rod 902 can drive the plurality of T-shaped push blocks 903 to move through the push plate 901 to push the angle steel, the right side of the right supporting plate 2 is fixedly connected with two control switches, the upper control switch is electrically connected with the first electric telescopic rod 401, and the lower control switch is electrically connected with the multi-stage electric telescopic rod 902, so that the first electric telescopic rod 401 and the multi-stage electric telescopic rod 902 can be conveniently controlled to be turned on.

[0034] Working principle: in use, first, the plurality of angle steels to be cut are placed in the corresponding angle steel placing grooves 101, and the rear side of the angle steel is in movable contact with the front side of the corresponding T-shaped push block 903. When cutting, the upper control switch is controlled to open the first electric telescopic rod 401 in the forward direction. The output shaft of the first electric telescopic rod 401 drives the mounting plate to move downward. The mounting plate drives the plurality of angle steel cutting blades 402 to move downward. At the same time, the mounting plate drives the transparent protective cover 501 to move downward in turn through the two L-shaped guide rods 503 and the two springs 504. The transparent protective cover 501 drives the back-shaped rubber pad 502 and the plurality of triangular rubber pressing blocks 505 to move downward. The plurality of triangular rubber pressing blocks 505 move downward and are respectively moved into the corresponding angle steel placing grooves 101 and come into contact with the angle steels. When the back-shaped rubber pad 502 and the triangular rubber pressing blocks 505 come into contact with the top of the base 1 and the corresponding angle steels respectively, the movement of the transparent protective cover 501 is limited. At this time, the L-shaped guide rod 503 that continues to move moves downward and compresses the corresponding spring 504. The spring 504 generates a downward extrusion force on the transparent protective cover 501. The transparent protective cover 501 drives the plurality of triangular rubber pressing blocks 505 to press and fix the corresponding angle steels respectively. After the angle steels are fixed, the mounting plate that continues to move drives the plurality of angle steel cutting blades 402 to cut the corresponding angle steels respectively. In the cutting process, the displacement of the angle steels during cutting is effectively reduced by the triangular rubber pressing blocks 505, and the cutting stability is improved. In addition, in the cutting process, the cutting area is protected by the transparent protective cover 501, which can effectively reduce the splashing of cutting slag outward.

[0035] The cutting slag is dropped into the mounting hole 102 through the corresponding slag dropping hole 103. The transparent protective cover 501 also drives the pressure block 7 to move downward and extrude the pressure sensor 8 when it moves downward. When the pressure sensor 8 detects the extrusion force, it transmits a signal to the PLC controller 10. When the PLC controller 10 receives the pressure, it controls the air pump 601 to open. The air pump 601 sucks the inside of the mounting hole 102 through the conical cover 604. Under the suction force, the inside of the plurality of angle steel placing grooves 101 can be sucked through the plurality of slag dropping holes 103. Thus, the residual cutting slag in the angle steel placing grooves 101 can be sucked into the mounting hole 102. The mounting hole 102 collects the cutting slag together with the L-shaped filter screen 602. Thus, the purpose of sucking and collecting the cutting slag during cutting is achieved. By blocking the cutting area and sucking and collecting the cutting slag, the risk of cutting slag splashing onto the body of the personnel is effectively reduced, and the cutting slag is collected together for subsequent cleaning by the personnel.

[0036] After the first cutting of the angle steel, the first electric telescopic rod 401 is started reversely, and the movement process is contrary to that of the first electric telescopic rod 401 started forwardly, so that the mounting plate drives the plurality of angle steel cutting blades 402 to separate upward from the plurality of angle steels, and the mounting plate also drives the two L-shaped guide rods 503 to relax the compression force of the spring 504; when the spring 504 is completely reset, the transparent protective cover 501 is driven to move upward, the transparent protective cover 501 drives the back-shaped rubber pad 502 and the triangular rubber pressing block 505 to move upward to release the compression of the angle steel, and then the control switch below is started forwardly to open the multi-stage electric telescopic rod 902, the output shaft of the multi-stage electric telescopic rod 902 drives the plurality of T-shaped push blocks 903 to move forward through the push plate 901 to push the plurality of angle steels forward, when the angle steels move forward to the appropriate position, the multi-stage electric telescopic rod 902 can be closed, and then the first electric telescopic rod 401 can be started forwardly again to perform the next shearing operation, and the plurality of angle steel position movements are synchronously driven by the electric driving mode, which is convenient for personnel operation and improves the work efficiency.

[0037] In the later cleaning, the U-shaped handle can be directly pulled to the left to drive the L-shaped filter screen 602 to move out of the mounting hole 102 through the baffle 603, the L-shaped filter screen 602 drives the internal cinder to move out of the mounting hole 102, and the cinder can be cleaned.

[0038] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited to this, any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
