Movable lower side door frame shaping device and method

The invention relates to the technical field of shaping devices for wagons, in particular to a movable lower side door frame shaping device and method. A shaping jaw is controlled to slightly move toenter a to-be-shaped part of a lower side door frame, after shaping of the single side of the lower side door frame is completed, shaping work of the other side of the lower side door frame can be achieved through transverse moving of an adjusting platform, the problem of existing wagon lower side door manual work is solved, all the processes are in mechanical operation, the labor intensity is lowered, and the work efficiency is obviously improved. The movable lower side door frame shaping device comprises a frame shaping device and the adjusting platform, the adjusting platform is used for driving the frame shaping device to move horizontally; and the frame shaping device comprises a bearing frame and a guide rod, the end, stretching out of the bearing framework, of the guide rod is fixedly provided with a connec
