The present disclosure discloses a method for forming a rim of a cast-spun aluminum alloy hub, that is, a special spinning composite machining method for forming a structure that the spokes and the inner wheel flange of the hub are cast and the middle of the rim is spun. The method can prevent the performance, strength and as-cast structure of the inner wheel flange from being destroyed, effectively improve the impact resistance of the cast-spun hub at the inner wheel flange, prevent the inner wheel flange of the cast-spun hub from cracking during radial impact and improve the performance of the spun structure of the rim, is beneficial to thinning the rim and realizes light weight of the rim.

A size-adjustable adaptive online wheel deburring device, including a synchronous clamping and rotating system for fixing and rotating a wheel, a left brush system, and a right brush system. The left brush system includes a first belt-type brush with a T-shaped synchronous belt at its inner side and bristles at its outer side, and a first automatically adjusting mechanism for changing a shape of the first brush by engaging the T-shaped synchronous belt so that the shape of the first brush is able to match different back cavity shapes of the wheel during burr removal. The right brush system includes a second belt-type brush and a second automatically adjusting mechanism for changing a shape of the second brush so that the second brush is constantly in three-point contact with a position of the wheel to be deburred during the burr removal.
