The utility model relates to an oxygen lance spray nozzle warm extrusion die. The oxygen lance spray nozzle warm extrusion die is characterized by comprising an upper die assembly, a lower die assembly, a guide sleeve and a guide column, wherein the upper die assembly is connected with the lower die assembly through the guide sleeve and the guide column. Compared with the prior art, the oxygen lance spray nozzle warm extrusion die has the advantage of being simple in structure, reasonable in design, high in utilization rate and small in processing difficulty. In addition, an oxygen lance spray nozzle crown blank can be formed in one time, spray nozzle crown metal fiber is continuous, grain size is small, oxygen content is low, and copper purity is high. Furthermore, the upper die assembly is connected with the lower die assembly through the guide sleeve and the guide column, the positioning accuracy of the upper die assembly and the lower die assembly is improved, the die can be repeatedly repaired and used for multiple times, and resource waste is reduced.
