An Aluminium Extrusion Die Inlayed with Cemented Carbide at Room Temperature
The properties and characteristics of aluminium extrusion die materials were introduced.A method of inlaying cemented carbide on extrusion die at room temperature was presented.The principle of this inlay method was described,which adopted a slant-ed matching and compensational inlay structure,utilizing the characteristics of automatic compensation and self-locking of the slanted structure.The design parameters for implementing cemented carbide inlay structures were described,and the results of using traditional die and cemented carbide die were compared.The results show that this new type of die inlayed with cemented carbide is worth repli-cating and promoting,and can be used as a reference for peers.
