Problems solved by technology

[0003] The quality of the wheel hub will greatly affect the quality of the car, and in the prior art, the preparation method of the wheel hub is often made by extrusion molding, which often forms indentations on the surface, resulting in poor quality of the wheel hub. At the same time, conventional aluminum Alloy materials often also greatly reduce the stress effect of the wheel hub when preparing the aluminum alloy wheel hub

Embodiment Construction

[0019] The best embodiment of the present invention will be further described in detail below.

[0020] The casting method of the wheel hub includes aluminum, iron, manganese, magnesium, zinc, chromium, copper, nickel and tungsten; wherein, the mass percentages of various components are: iron is 10-50%, manganese is 1-10% , magnesium is 5-15%, zinc is 1-10%, chromium is 1-5%, copper is 1-5%, nickel is 1-5%, tungsten is 3-10%, and the rest is aluminum.

[0021] In further implementation, the mass percentages of the various components are: 30% iron, 5% manganese, 10% magnesium, 6% zinc, 3% chromium, 3% copper, 3% nickel, tungsten 7% and the rest is aluminum.

[0022] Include the following steps:

[0023] Step 1, mixing various materials in proportion and then smelting to obtain a smelting solution;

[0024] Step 2. Keep the above-mentioned smelting liquid at a constant temperature of -0.6-0.8pa for 8-12 minutes, then press it into the mold and cast it into shape; this process...

Abstract

The invention discloses a casting method of a hub. The hub comprises the following components by pass percent: 10 to 50% of iron, 1 to 10% of manganese, 5 to 15% of magnesium, 1 to 10% of zinc, 1 to 5% of chromium, 1 to 5% of copper, 1 to 5% of nickel and 3 to 10% of tungsten, and the balance being aluminium. According to the casting method, the hub is high in strength, good in toughness, good in quality, free of impressions, and not liable to deform, the impact resistance is high, and the popularization of a product is facilitated.

Description

technical field [0001] The invention belongs to the technical field of automobile supplies, and in particular relates to a casting method of a 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] The quality of the wheel hub will greatly affect the quality of the car, and in the prior art, the preparation method of the wheel hub is often made by extrusion molding, which often forms indentations on the surface, resulting in poor quality of the wheel hub. At the same time, conventional aluminum Alloy materials often also greatly reduce the stress effect of the wheel hub when preparing the aluminum alloy wheel hub. Contents of the invention [0004] The purpose of the present invention is to propose a casting method for a wheel hub, which overcomes the deficiencies of the prior art. The wheel hub has...
