Abstract

The invention discloses a manufacturing process of an aluminum alloy wheel, which comprises the following steps: step 1) forming a casting blank in a low-pressure casting mode; step 2) forming a positioning hole on a spoke blank of the casting blank; step 3) preheating the casting blank by a first heating device; step 4) cooling the spoke blank of the casting blank; step 5) mounting the casting blank to a spinning machine; step 6) spinning a wheel rim blank of the casting blank by the spinning machine, heating the wheel rim blank by a second heating device to sufficiently ensure that the spinning temperature is not reduced and simultaneously the wheel rim blank keeps certain plasticity to control the deformation and the deforming speed of the wheel rim blank in the hot spinning process soas to obtain a crude product with good appearance and mechanical properties; and step 7) to step 9) performing heat treatment, mechanical processing and arrangement on the crude product so as to obtain the aluminum alloy wheel with low cost, light weight and good mechanical properties.

Description

【Technical field】 [0001] The invention relates to a manufacturing process of an aluminum alloy wheel, in particular to a casting and spinning process of an aluminum alloy wheel. 【Background technique】 [0002] Wheels are one of the parts related to automobile safety, which can be divided into steel wheels and aluminum alloy wheels. Compared with steel wheels, aluminum alloy wheels have light weight, high strength, good braking balance performance, and high precision. High, good thermal conductivity, low fuel consumption and many other advantages, so aluminum alloy wheels have a wide range of application prospects. Common manufacturing methods of aluminum alloy wheels can be divided into six categories: forging, semi-solid casting (squeeze casting, liquid forging), low-pressure casting, gravity casting, differential pressure casting, and assembly. Among them, the most rigid and lightest It is a forging method. The so-called forging is to extrude a whole piece of aluminum in...
