Description

Technical Field

[0001] The utility model relates to the field of extruders, in particular to a copper and aluminum profile extruder. Background Art

[0002] Metal extruders are the primary equipment for metal extrusion processing. Metal extrusion is a crucial method for forming metals using plastic pressure. Its key feature is that it can instantly process metal ingots into tubes, rods, and profiles, a feat that few other methods can rival. Common extruders include copper and aluminum profile extruders.

[0003] However, the middle section of a general extruder is an open space and is not sealed. One side of the middle section of the extruder is often a feeding table and a heating furnace. Feeding in an open space often has a certain heat dissipation and cooling effect on the heated material, causing the heated material to cool down quickly and achieving a good extrusion effect. Sometimes it even needs to be heated even hotter when passing through the heating furnace, which also increases energy consumption.

[0004] Therefore, the utility model provides a copper and aluminum profile extruder, in which a heat-insulating protective metal plate is installed in the middle section of the extruder, so that both ends of the copper and aluminum rod feeding platform can be closed, ensuring that the heated metal material during feeding from the copper and aluminum rod feeding platform will not cool down, allowing extrusion to proceed smoothly, and a through hole is opened in the center of the closed metal plate, and the extrusion rod passes through the through hole and then is squeezed into the extrusion cylinder to protect the extrusion rod. Utility Model Content

[0007] In a preferred embodiment of the present invention, the bottom of the step-type fixed base is fixedly mounted on the extruder body, and the closed metal plate and the step-type fixed base are an integral structure.

[0008] In a preferred embodiment of the present invention, both ends of the copper and aluminum rod feeding platform are separated by the heat-insulating protective metal plate, and the copper and aluminum rod feeding platform is located in the space separated by the heat-insulating protective metal plate.

The first thermal insulation and protective metal plate is arranged at the front end of the second thermal insulation and protective metal plate, and the through holes opened on the second thermal insulation and protective metal plate are larger than the through holes opened on the first thermal insulation and protective metal plate.

[0010] In a preferred embodiment of the present invention, the extrusion cylinder propulsion device is connected to an extrusion cylinder speed control mechanism, and the extrusion cylinder speed control mechanism controls the extrusion cylinder propulsion device to drive the extrusion rod to advance.
