The invention discloses an automobile aluminum alloy hub forging method. The automobile aluminum alloy hub forging method comprises the following steps that S10, a material blank is heated, and the material blank is heated to a preset forging temperature; S20, the heated material blank is placed on a first forging station of a lower die assembly, an upper die is aligned with a lower die of the first forging station and moves downwards, the upper die, a half die ring and the lower die are matched with one another, the first forging procedure of the material blank is achieved, and a first forged and formed hub is obtained; and S30, the lower die assembly moves a second forging station to the position below the upper die, the upper die and the half die ring move downwards and are matched with the lower die, a second forging procedure is carried out on the first forged and formed hub, and a second forged and formed hub is obtained.
Description
technical field [0001] The invention relates to the field of automobile molds, in particular to a method for forging an automobile aluminum alloy wheel hub. Background technique [0002] The wheel hub is the rotating part of the wheel core connected by the inner profile of the tire through the column, that is, the metal part that supports the center of the tire and is mounted on the shaft, also called the wheel rim, steel ring, wheel, tire bell, it is an indispensable part of the car . [0003] The traditional aluminum alloy wheel manufacturing process is to die-cast an aluminum alloy wheel blank by a die-casting machine, such as figure 1 Shown: Blank with spokes and part of rim, no rim. Flared after the blank (see figure 2 ), spinning (see image 3 ) to form a complete hub. The disadvantage of this process is that the process is complicated. It needs to melt the aluminum material to die-cast a blank, then use a press to expand the rim, and then use a spinning machine ...
