In this embodiment, as shown in FIGS. 13 and 14, when the aluminum alloy rim 3 having the rib 30 and the wheel 34 are locked, the two aluminum alloy rims 3 can be convex. Between the ribs 30 facing each other, a rubber ring 32 is placed, and when the mixed alloy rim 3 and the wheel 34 are firmly locked together, the rubber ring 32 is used in the alloy ring 3 After the shock into a tire, the air in the tire can be prevented from leaking from the gap between the faces of the ribs 3〇 facing each other. In summary, the effect and purpose of the method for manufacturing the alloy rim of the invention are as follows: 1. Because the method of the invention does not need to use a rim mold, it is easy to use a large number of roller presses. Eliminating the production costs required to set up an expensive machine, it can also greatly vacate the room. In the eighth aspect of the invention, the invention is made by continuously bending to make the aluminum alloy rim 3, without the need for the knife slave to suppress the pressure, and eliminating the troublesome and time-consuming hook, resulting in the production of the legendary circle 3 Yusheng 7 Go, because the unevenness of the rolling pressure is low. . Gold ring 3 occurs "distribution unevenness or 13! 277466, 3. The size of the gold ring 3 of this age can be changed at any time, and the larger size _ alloy rim 3 can be produced, which is elastic on the top. 4. When the aluminum alloy rim 3 of different sizes is to be manufactured, it is not necessary to replace any implement or process, and the object of the rim of the rim is substantially changed as described above, and is only one of the best embodiments of the present invention.
