s3: moving a positioning circular die (7) to the position of a hole to be cut by moving a front limiting plate (1), enabling a compression screw (6) to compress a guide plate (3), fastening the positioning circular die (7) at the position of the hole to be cut, cutting holes in a web plate of profile steel (15) along a plurality of circular arc section positioning holes concentric with the center of a circle on the positioning circular die (7), placing a limiting circular die (8) into the cut holes, moving a rear limiting plate (2) to the position of the limiting circular die (8), fixing the rear limiting plate and the limiting circular die (8) through bolts, moving the front limiting plate (1), and measuring the position of the next hole to be cut by using a measuring scale (4);
s4: s3 is repeated until all the holes on the web of the section steel (15) are cut.
