Abstract

See full text

The disclosure discloses a method for manufacturing special purpose vehicle wheels by using 7000 series aluminum alloys, comprising the following steps: step 1, smelting 7000 series aluminum alloys in a smelting furnace; step 2, making the solution obtained in step 1 into an aluminum alloy ingot blank through a spraying and forming process; step 3, extruding the aluminum alloy ingot blank of step 2 to obtain an extrusion bar; step 4, sawing the extrusion bar into blanks and heating them; step 5, rolling the blank into a cake; step 6, putting the cake into a press for forging and forming; step 7, spinning and forming the wheel rim. The wheel manufactured by the method for manufacturing special vehicle wheels with 7000 series aluminum alloys in the present disclosure has high and stable conductivity, qualified impact test and good bending and radial fatigue performance.
