ABSTRACT:
The manufacturing method for an aluminum alloy wheel rim consists of the following steps: (1) cutting aluminum alloy material; (2) heating the aluminum alloy material to make a marked center and fillet preformed blank; (3) forging the marked center and fillet preformed blank into a preformed blank; (4) punching a central axis of the preformed blank; (5) forging the punched preformed blank into an enlarged rough forging blank; and (6) forging the enlarged rough forging blank to form an aluminum alloy wheel rim. With this presenting invention the structural strength of the wheel rim is enhanced. In addition, the aluminum alloy wheel rim can be manufactured rapidly, thereby enhancing efficient productivity and improving quality of fabrication of the wheel rim.
