The research object is an A356 aluminum alloy wheel hub of a domestic passenger car brand, with a wheel hub model size of 19 × 8J PCD -5 × 112, its appearance is shown in Figure 1. As a key component, the wheel hub determines the reliability of the...
Low pressure casting, as a mature casting process, has the characteristics of smooth filling, low cost, and good casting quality, and is widely used in the production of automotive components such as wheels. However, as the lightweight of auto parts is included in the development plan of “Made in...
1. Production of automobile aluminum alloy wheels In order to fully demonstrate the superior performance of wheel hub and apply it to automobile production, aluminum alloy has become the preferred material for automobile wheel manufacturing, and the output of aluminum alloy has increased year by year. Through the analysis...
1. Development origin of automobile aluminum alloy wheels The manufacturing of aluminum alloy wheel in foreign countries has experienced the development process from sand casting to aluminum alloy integral wheel, which was widely used in ordinary cars after World War II. The rapid development of automobile aluminum alloy wheel...
The wheel hub is the key to the car styling. The performance of the wheel hub itself is directly related to the overall performance of the vehicle and is an important guarantee for the personal safety of passengers. In recent years, aluminum alloy wheels have been widely used in...
It can be seen from the analysis that there is no liquid metal feeding at the center of the wheel due to the early solidification around the wheel, resulting in shrinkage porosity and shrinkage defects. In order to solve the problem that molten metal cannot be fed in time,...

1. Model establishment Figure 1 is a three-dimensional part drawing of the wheel of a mining flat car, with an outline dimension of 353 mm × 403 mm × 152 mm, the wall thickness of the outer ring of the wheel is 20 mm, and the wall thickness of...
Wheel is one of the important parts of mining flat car. It needs to bear large alternating stress and bending stress when working. This special working condition often leads to bending, cracks, wear and other problems. Therefore, higher requirements are put forward for the wheel casting process, and the...
1. Large hydraulic press Composite squeeze casting is a new squeeze casting method proposed in. At present, there is no special forming equipment, but the general four column hydraulic press can be modified to realize the functions required for the composite squeeze casting of large parts. As the formed...
