Technical Field

[0001] The utility model belongs to the technical field of mechanical processing, in particular to a guide device for hot-extruded tubes and rods of a large vertical extruder. Background Art

[0002] The extruder is used to extrude seamless pipes and is often used in the processing of aluminum alloy pipes. After the extruder extrude the pipe product, the pipe product is separated from the extruder and further transferred.

[0003] During the existing hot extrusion of large-diameter pipes and bars, the pipes and bars move vertically upward along the inner holes of the extrusion die seat backing ring, the extrusion die seat and the movable beam. Since the pipes and bars are now in a high-temperature state and the inner holes of the extrusion die seat lining, the extrusion die seat and the movable beam are relatively large, the pipes and bars tilt to one side, resulting in bending of the pipes and bars. The head of the pipes and bars can only be cut off by sawing to become waste. Such pipes and bars have low material utilization, increase manufacturing processes and construction period, resulting in high production costs, waste of energy and resources, etc.
