METHOD AND DEVICE FOR ALUMINIUM DUPLEX HOLLOW STRUCTURAL FRAME AND ALUMINIUM DUPLEX HOLLOW STRUCTURAL FRAME

摘要

A production of hollow structure ash with a superior intensity the core of the aluminum hot extrudsion mold is made independently of the extruding mold with the thermal process one separable and possible for the core replace the manufacturing method of the aluminum duplex hollow structure ash for being possible and manufacturing device and aluminum duplex hollow structure is provided. An aluminum duplex hollow structure(A) comprises a nitrogen cooling heartburnings core rod(2) after precooling it vacuously thermallies process in the vacuum heat treating furnace; a main body(4) in which the molding globe(18) is protruded to one side; a head unit(22) combined in the sieve in which the shaping hole is formed so that the molding outlet of the main body be inserted. The Aluminum Billet(6) which becomes heated is injected in the organized extrusion molded part(B) in the extrusion process furnace by the fixed temperature and it characterizes to be formed with extrusion manufacturing.
