step 5-1, the steel plate is contacted with a supporting roller (4), the supporting roller (4) and a pressing roller (24) roll the steel plate, and the steel plate generates a certain curvature;
step 5-2, then the steel plate enters the guide curved surface (52) along a tangent plane of the support roller (4) overlapped with the guide curved surface (52), the steel plate is driven by the press roller (24) to continuously move, the guide curved surface (52) presses the steel plate to continuously move, and the steel plate is continuously bent to a curvature smaller than the curvature of the guide curved surface;
step 5-3, guiding out the steel plate along the other tangent plane of the supporting roller (4) which coincides with the guiding curved surface (52), and enabling the steel plate to enter the supporting roller (4) which is guided out from the guiding curved surface (52);
step 6, continuously rolling a certain curvature on the steel plate by the other derived supporting roller (4) and deriving;
step 7, repeating the steps 1-6 for 5-10 times until the head end and the tail end of the steel plate are close to each other for the first time;
step 8, repeatedly rolling the steel plate until the head end and the tail end of the steel plate are in contact with each other, and forming a roller by the steel plate;
step 9, the gear motor (21) is powered off, the reciprocating linear motor (32) is powered off, the hydraulic telescopic rod (25) stretches, and the hydraulic telescopic rod (25) drives the movable arm (23) to move to the highest point;
step 10, screwing off a locking bolt (243), taking down a pressing block (22), separating a press roller inner shaft (242) from a power shaft of a speed reducing motor (21), taking out a roller and a press roller (24) together, and taking down the roller from the press roller (24);
and 11, putting two ends of the press roller (24) on the movable arm (23) again, installing the press block (22), screwing the locking bolt (243), connecting the inner shaft (242) of the press roller with a power shaft of the speed reducing motor (21) again, and reinstalling the press roller (24).
