Claim 9:
10. A production method of H-shaped steel based on the production line of H-shaped steel of claim 1, which is used to fixedly weld stiffening plates at several specified positions on an H-shaped workpiece, wherein the method comprises:
S1: actuating a transfer device to move the H-shaped workpiece from a temporary storage zone to an assembly line of an assembly zone, and actuating an anti-falling device on the assembly line to fix the H-shaped workpiece;
S2: carrying a stiffening plate by a carrying robot to a specified station on the assembly line, attaching the stiffening plate to the H-shaped workpiece for a specified period of time, and performing spot welding and fixing of the stiffening plate and the H-shaped workpiece by a spot welding robot;
S3: executing step S2 until all required stiffening plates are assembled on the H-shaped workpiece on the assembly line;
S4: resetting the anti-falling device, actuating the transfer device to move the H-shaped workpiece assembled with the stiffening plate to a welding line, and then actuating an anti-falling device on the welding line to fix the H-shaped workpiece;
S5: welding the stiffening plate and the H-shaped workpiece by welding robots;
S6: executing S5 until all stiffening plates on the welding line are welded and the required H-shaped steel is obtained; and
S7: resetting the anti-falling device and actuating the transfer device to discharge the H-shaped steel from the welding line.
