Aluminum extrusion composite member, manufacturing method and manufacturing apparatus thereof

Abstract

An aluminum extrusion composite member manufacturing method includes the steps of providing an extrusion mold; introducing at least one metal wire into the extrusion mold; and placing an aluminum material in a container and extruding the aluminum material into the extrusion mold to advance the at least one metal wire to form an aluminum extruded composite member containing the at least one metal wire therein.

What is claimed is: 
     
         1 . An aluminum extrusion composite member comprising:
 a hollow aluminum alloy body having a cross-section of substantially the same shape over an entire length thereof, wherein the cross-section is substantially perpendicular to a longitudinal axis of the aluminum alloy body; and   at least one metal wire disposed within the aluminum alloy body and along the longitudinal axis of the aluminum alloy body.   
     
     
         2 . The aluminum extrusion composite member of  claim 1 , wherein the at least one metal wire is made of a material of a melting point and mechanical strength greater than aluminum is. 
     
     
         3 . The aluminum extrusion composite member of  claim 1 , wherein the at least one metal wire is located at a corner of the cross-section of the aluminum alloy body. 
     
     
         4 . An aluminum extrusion composite member manufacturing method comprising:
 providing an extrusion mold;   introducing at least one metal wire into the extrusion mold; and   placing an aluminum material in a container and extruding the aluminum material into the extrusion mold to advance the at least one metal wire to form an aluminum extruded composite member containing the at least one metal wire therein.   
     
     
         5 . The aluminum extrusion composite member manufacturing method of  claim 4 , wherein the aluminum material is extruded to be split and then merged within the extrusion mold, and the at least one metal wire is brought into the aluminum material when the aluminum material is merged within the extrusion mold. 
     
     
         6 . The aluminum extrusion composite member manufacturing method of  claim 4  further comprising:
 positioning at least one guide pin within the extrusion mold where the aluminum material is merged to introduce the at least one metal wire into the aluminum material. 
 
     
     
         7 . An aluminum extrusion composite member manufacturing apparatus comprising:
 a container for accommodating an aluminum material;   an extrusion mold connected to the container for shaping the aluminum material, the extrusion mold having an extrusion channel through which the aluminum material is extruded and shaped into a desired cross-section; and   a wire-feeding device located at a side of the extrusion mold for supplying a metal wire to be guided into the extrusion channel.   
     
     
         8 . The aluminum extrusion composite member manufacturing apparatus of  claim 7 , wherein the extrusion channel comprises multiple branching passages followed by a merging passage, the multiple branching passages serve as a feed end of the aluminum material and the merging passage serves as an output end of the aluminum material. 
     
     
         9 . The aluminum extrusion composite member manufacturing apparatus of  claim 8  further comprising a guide pin within the merging passage, and the guide pin is aligned with one of the multiple branching passages. 
     
     
         10 . The aluminum extrusion composite member manufacturing apparatus of  claim 9  further comprising a reel around which the metal wire is pre-wound, and the reel supplies the metal wire to the guide pin.
