The steel cutting method of the present invention is used for the steel cutting device described in the above embodiment, and includes the steps of:
starting a second electric push rod 64 according to the cutting length requirement of the steel pipe, so that the second electric push rod 64 drives the positioning plate 63 to move to a proper position;
installing steel pipes between the clamping arms 6 of each clamping group, and controlling the first electric push rod 52 to extend so that the clamping arms 6 clamp the steel pipes;
starting a driving motor 2, driving a cutter 21 to move downwards to cut a steel pipe through an operation handle 22, wherein in the cutting process, the cutter 21 extrudes the steel pipe to drive a clamping arm 6 and a mounting block 5 to move downwards, the mounting block 5 drives a supporting plate 4 to extrude a first spring 43 downwards through a gear 51 and a stud 44, meanwhile, the gear 51 on the mounting block 5 rotates along a rack 33 to drive the mounting block 5 to move along the stud 44 towards a direction close to the clamping arm 6, a mounting plate 53 on the mounting block 5 moves towards a connecting groove and extrudes a third spring 8, and when a limiting block 7 is aligned with a limiting groove 62, a second spring 71 extrudes the limiting block 7 to move towards the limiting groove 62, so that the part of the limiting block 7 provided with a first inclined wedge surface 72 enters a reset groove 92 in the limiting groove 62;
