Zinc alloy wires are used in a large number in the fields of metal surface corrosion prevention and hardware products, and the wires are generally prepared by adopting an extrusion method. The conventional vertical extruder is adopted to extrude wires, the tonnage of the general extruder is not more than 450 tons, the weight of an extrusion ingot is not more than 4kg, an extrusion die barrel and an extrusion die are combined and fixed together, the extrusion process cannot be separated, lubricating oil added to the surface of the extrusion ingot in the extrusion process and air in the extrusion die barrel cannot be completely discharged, defects can be formed in the wires by extrusion, and the using effect is affected. Meanwhile, the conventional zinc alloy extrusion ingots are only suitable for a single ingot casting method, each extrusion ingot is provided with a casting nozzle, so that in order to avoid the defect of the casting nozzle of the extrusion ingot from being brought into extrusion wires, the casting nozzle of the extrusion ingot needs to be cut off in advance, and therefore part of alloy is lost. To improve extrusion efficiency and wire quality, large tonnage extruders are a good solution, but large tonnage extruders are typically arranged horizontally. The horizontally arranged large-tonnage extruder is commonly used for processing copper and aluminum wires, and the extrusion die barrel can be opened and closed in the extrusion process, so that the lubricant added on the surface of the extrusion ingot and the air in the extrusion die barrel can be smoothly discharged, and the quality of the wires is improved.

Since the extruded wire 6 is long, it cannot be withdrawn from the forming die 5 by way of retraction. The end 4 is usually removed from the wire 6 by cutting, and the wire 6 is welded again after cutting to reduce the diameter, so that the extruded ingot is fully used. The method has long process flow and low production efficiency, and cannot meet the requirements of the industry. There is therefore a need to propose a new solution to this problem. .
