Technical Field

The invention belongs to the technical field of aluminum alloy wheels, and particularly relates to a metal mesh composite casting aluminum alloy wheel.

Background

Wheels are generally considered the oldest and most important invention for humans, so that we often refer to it and the use of fire. In fact, the history of human domestication of fire has been over 150 ten thousand years, and the beginning use of wheels has only been a region of six thousand years carrying light and shade.

The existing wheels comprise steel wheels, aluminum alloy cast wheels and aluminum alloy forged wheels, the steel wheels have the advantage of high bearing capacity, but the weight of the steel wheels is 2-3 times that of the aluminum alloy wheels, so that the oil consumption and the weight of the whole vehicle are increased, and the aluminum alloy wheels gradually become standard fittings. The cost of the cast wheel is far lower than that of the forged wheel, the internal porosity problem caused by casting is optimized along with the maturity of the casting process, but the performance of the cast product is certainly lower than that of the forged wheel with the same quality, and in addition, the existing wheel hub does not have the waterproof function.

Disclosure of Invention

The invention aims to provide a metal mesh composite casting aluminum alloy wheel to solve the problems in the background technology.

In order to solve the technical problems, the invention provides the following technical scheme:

the invention provides a metal mesh composite casting aluminum alloy wheel which comprises a wheel hub blank, wherein a metal mesh is arranged inside the wheel hub blank, an upper film limiting block and a lower film limiting block are respectively arranged on the upper surface and the lower surface of the metal mesh, one side of the surface of the wheel hub blank is fixedly connected with an installation ring, and a waterproof panel is arranged on the outer surface of the installation ring.

As a preferred technical scheme of the invention: the waterproof panel is fixedly connected with the mounting ring through a plurality of mounting screws.

As a preferred technical scheme of the invention: the metal diameter of the metal net is 3mm-8 mm.

As a preferred technical scheme of the invention: and carrying out rust removal and oil removal treatment before forging the metal mesh.

The invention has the following beneficial effects: according to the invention, the wall thickness of the casting blank can be reduced by 2mm-3mm at the same ratio by arranging the metal mesh, so that the problem of internal looseness of a composite part is reduced, the production efficiency is synchronously improved, the product percent of pass is improved, and meanwhile, the waterproof panel is arranged on the surface of the mounting ring, so that the waterproof effect is achieved on the hub.
