  • Patent number: 11904412
    Abstract: The present disclosure relates to the technical field of production of H-shaped steel and discloses a production line of H-shaped steel and a production method. By arrangement of the assembly zone in which a welding line is arranged and the welding zone in which a welding line is arranged, a process layout of assembly and welding flow type machining production line can be formed. Assembly and welding of a stiffening plate are operated independently, and a carrying robot, a spot welding robot and a welding robot are movable between stations. A transfer device transfers an H-shaped workpiece in the process of feeding, machining and discharging, thereby implementing flow type machining, which can effectively improve machining efficiency. Through the production method, the assembly and welding flow type machining of the stiffening plate can be implemented, thereby effectively improving machining efficiency.
