The invention discloses aluminum alloy wheel shape-correcting equipment which comprises rack, an output end of positioning air cylinder is arranged at the bottom of the rack corresponding to the center of the upper rotating disc and is vertically and upwards connected with positioning cone.

Some embodiments of the present disclosure provide manufacturing methods for a wheel rim, a spoke and a steel wheel and a steel wheel formed by the methods. The methods includes that: a wheel rim/a spoke blank is heated in a heating furnace, and the heated wheel rim/the heated spoke blank is transferred onto a hot press. A temperature of the wheel rim/the spoke blank being required to be kept above a required temperature in a process of transferring the heated wheel rim/the heated spoke blank to the hot press. Then the wheel rim/the spoke blank is formed in the hot press. A formed wheel rim and a formed spoke are connected to product a steel wheel.

A spinning apparatus for decreasing by spinning a thickness of a portion of a tube material having a uniform thickness except at a first axial end portion is disclosed. The spinning apparatus includes a spindle-side chuck having a conical concavity and a mandrel. The mandrel has a mandrel-side chuck formed in a form of a conical convexity corresponding in configuration to the conical concavity of the spindle-side chuck and a cylindrical portion for supporting the tube material. The spinning apparatus further includes a spinning roll for decreasing the thickness of the tube material by pressing the spinning roll against the tube material when the tube material is supported by the cylindrical portion of the mandrel.
