Example Embodiment

[0020] The best embodiment of the present invention will be described in further detail below.

[0021] In the manufacturing method of the aluminum wheel hub, each composition and mass percentage are: Cu2.2-4.9%; Mg0.2-1.8%; Mn0.3-0.9%; Si0.1-0.2%; Zn2-5%; Cr0.3-0.52%; Pr0.0001-0.002%; the rest is Al.

[0022] In further implementation, each composition and mass percentage are: Cu3%; Mg1%; Mn0.6%; S0.2%; Zn3%; Cr0.4%; Pr0.001%; ​​the rest is Al.

[0023] It includes the following steps:

[0024] (1) Prepare an integrated wheel hub mold;

[0025] (2) Lay a high temperature resistant template on the middle layer of the wheel hub mold;

[0026] (3) Lay the duralumin alloy metal powder layer by layer with the high temperature template as the support in the wheel mold. After laying a layer of 3mm thick duralumin alloy metal powder, use the laser beam to melt the duralumin alloy metal powder, and then lay the next layer of 3mm. Thick hard aluminum alloy metal powder and melt it with a laser ...

Abstract

The invention discloses a manufacturing method of an aluminum hub. The aluminum hub comprises, by mass, 2.2%-4.9% of Cu, 0.2%-1.8% of Mg, 0.3%-0.9% of Mn, 0.1%-0.2% of Si, 2%-5% of Zn, 0.3%-0.52% of Cr, 0.0001%-0.002% of Pr and the balance Al. The aluminum hub is high in strength, good in tenacity and quality, high in machining precision, not prone to deformation, high in impact resistance and beneficial for product popularization.

Description

technical field [0001] The invention belongs to the technical field of automobile supplies, and in particular relates to a manufacturing method of an aluminum wheel hub. Background technique [0002] With the development of the motor vehicle industry, the output and stock of motor vehicles have increased, driving economic development and bringing convenience to people's travel. [0003] As the most intimate part of the road surface, the wheel hub is undoubtedly a vulnerable part on the car body, and the wheel hub is the most valuable part of the wheel. However, it will also deform when encountering a strong external impact. Usually, the damage to the wheel hub of a car is caused by external forces, such as wear, fracture, notch, corrosion, dent, distortion, deformation, etc. Such problems will seriously affect the driving safety of the vehicle. However, the most common damage to the wheel hub is the damage to the edge of the wheel hub. The main manifestations are: first, t...
