Magnesium alloy hub forging die

The invention discloses a manufacturing technology for an alloy wheel, and the alloy wheel. The manufacturing technology comprises the steps that a material is smelted and cast, and a cast blank of the wheel is formed; by utilizing the residual temperature of the cast blank, the cast blank is subjected to hot spinning, and a crude product of the wheel is obtained; and the crude product is subjected to subsequent machining, and the finished wheel product is obtained. By using the manufacturing technology, the residual temperature of the cast blank formed after the working procedures of smeltingand casting serves as the spinning temperature needed by the subsequent hot spinning procedure, a workpiece does not need to be additionally heated, and thus the technological complexity is lowered;and heat generated in the wheel manufacturing process can be reasonably utilized, and the heat loss in the wheel manufacturing process is reduced effectively.

The invention belongs to an H-shaped aluminum alloy wheel forging and forming process. The process procedure of the H-shaped aluminum alloy wheel forging and forming process includes the steps that firstly, a blank is heated, wherein the blank is a round rod, the heating temperature of the blank ranges from 400 DEG C to 500 DEG C, and the preheating temperature of a forging die ranges from 410 DEG C to 430 DEG C; secondly, hot die forging is performed, wherein after a spoke part is formed, an H-shaped rim with one side provided with a flare angle is pre-forged; and thirdly, two-way hot spinning is performed, wherein the H-shaped rim is formed in a two-way spinning manner. The forging and hot spinning forming process is adopted, the procedures of trimming, flaring, punching, pre-machining and the like which are performed after forging are not needed, the process flow is shortened, the blank is directly thermally treated after hot spinning, production cost is reduced, and production efficiency is improved.
