Railway wagon end wall flexible welding production line

The invention discloses a flexible welding production line for an end wall of a railway wagon, and relates to the technical field of railway vehicle production equipment.The flexible welding production line is characterized in that grouping and spot welding of end wall parts are completed through a feeding assembly pressing spot welding station, and then welding of front face flat welding seams, front face vertical welding seams and back face flat welding seams of the end wall parts is completed through different welding stations in sequence; and finally, stacking after manual repair welding. The stations are transported through the chain conveying device and the transfer trolley, so that unmanned circulation of key materials is achieved, the problems that the end walls are welded in a floor-spreading mode, the occupied area is large, the labor intensity is high, continuous production cannot be achieved, the production efficiency is low, and the environment is poor are solved in cooperation with the arrangeme
