Problems solved by technology
Aluminum alloy wheels produced by casting process inevitably have casting defects, resulting in low mechanical properties
The overall forging process of 6061 aluminum alloy will waste a lot of raw materials, resulting in higher production costs
In addition, in the existing technology, the 6061 alloy wheel produced by forging and spinning process is limited by the mechanical properties of the material, and the finished product cannot reach a new level in light weight

Abstract
The invention discloses an aluminum alloy hub manufacturing method. The aluminum alloy hub manufacturing method comprises the following steps of material preparing, specifically, an aluminum alloy blank is supplied, and a 6066 aluminum alloy is taken as the aluminum alloy; forging, specifically, the aluminum alloy blank is heated to 410-440 DEG C, heat preservation is conducted for a period of time, the aluminum alloy blank is forged into the blank needed by spinning, and a forged blank is obtained; spinning, specifically, the forged blank is put into a preheated spinning mold, and a spun blank is obtained through spinning; and aftertreating, specifically, heat treating and machining are conducted on the spun blank, and an aluminum alloy hub is obtained. According to the aluminum alloy hubmanufacturing method, the aluminum alloy hub is manufactured by taking the 6066 aluminum alloy as a raw material, and compared with a hub manufactured by the 6061 aluminum alloy in the prior art, theproduct weight can be significantly decreased under the same load intensity; and in addition, the method for manufacturing the aluminum alloy hub by adopting the 6066 aluminum alloy is simple, and the manufacturing efficiency can be improved.
Description
Technical field [0001] The invention relates to a method for manufacturing an aluminum alloy wheel hub. Background technique [0002] At present, domestically, A356 aluminum alloy die-casting process or 6061 aluminum alloy swaging process is usually used to produce aluminum alloy wheel blanks. The aluminum alloy wheels produced by the casting process inevitably have casting defects, resulting in lower mechanical properties. The 6061 aluminum alloy overall forging process will waste a lot of raw materials, resulting in higher production costs. In addition, in the prior art, the 6061 alloy wheel hub produced by the forging and spinning process is limited by the mechanical properties of the material, and the finished product cannot be further improved in weight reduction. Summary of the invention [0003] In order to overcome the disadvantages of the prior art, the purpose of the present invention is to provide a method for manufacturing an aluminum alloy wheel hub. Compared with t...
