5 axis CNC Impeller FAQs
Using forged wheel rims can effectively reduce vehicle wear and achieve advantages such as faster acceleration and better handling. Due to the higher strength and lighter weight of forged wheel rims, vehicles can accelerate quickly during starts and maintain better handling during everyday driving. This not only helps reduce fuel consumption and engine power usage, leading to fuel savings, but also improves overall energy efficiency with significant emission reduction effects. Furthermore, the superior performance of forged wheel rims contributes to extending the engine’s lifespan, providing reliable performance for vehicles.
We typically use 6061-T651 aluminum alloy to manufacture the wheel rim. This aluminum alloy is produced through a heat treatment and pre-stretching process, providing advantages such as lightweight, excellent corrosion resistance, high toughness, and minimal deformation after processing. 6061-T651 aluminum alloy is widely utilized in various fields, including transportation, electronics, aerospace, and defense, making it an ideal choice for the manufacturing of wheel rim due to its superior performance.
Steel wheel rim: Steel wheel rims are commonly made of steel, representing a cost-effective and widely used material. However, they have poor heat dissipation capabilities and are prone to rusting, especially in rainy and humid conditions.
Aluminum Alloy wheel rim: Aluminum alloy wheel rims are primarily composed of aluminum with the addition of metals like manganese and magnesium. Compared to steel wheel rims, they are lighter, contributing to fuel efficiency in vehicles equipped with aluminum alloy wheels.
Magnesium Alloy wheel rim: Magnesium alloy wheel rims are primarily made of magnesium with the addition of other metal materials. This material is the lightest among the options, gaining popularity among car owners. Magnesium alloy wheel rims offer good shock absorption performance, efficient heat dissipation, and corrosion resistance.
Carbon Fiber Composite Material wheel rim: Carbon fiber composite material wheel rims are made from composite materials, making them relatively expensive. However, they offer excellent noise resistance and are easily repairable even if damaged.
Automotive Parts Forging Process: This forging process may include gravity casting and low-pressure casting. Gravity forging involves a simple process where the liquid alloy is poured into the mold, naturally forming under gravity, resulting in relatively low costs. Low-pressure casting relies on low-pressure pressing of the liquid alloy into the mold. wheel rims produced using this method have relatively higher metal density, strength, and more complex shapes, ensuring a higher safety factor. It is currently a key mode for manufacturing aluminum alloy wheels with relatively high product yield and automation.
Automotive Parts Casting Process: With the assistance of high pressure, the heated alloy is pressed into the rough rim. After secondary production processing on the production line, the shapes are generally simple, and the surface of the wheel rim mostly features simple and rough lines.
Automotive Parts Spinning Process: This process has specific requirements for pressure and temperature. With the help of rotational motion and extrusion, the structure of the local positions of the wheel rim and rim is extended.
Material Selection: Choosing the right material is crucial, typically using aluminum alloy or steel. The material should possess sufficient strength, hardness, and corrosion resistance.
Process Specifications: Adhering to automotive manufacturing and safety standards to ensure the rim complies with the required performance and safety requirements.
Design and Dimensions: The design and dimensions of the rim should meet the requirements of the automobile manufacturer. Ensure the geometric shape, hole positions, bolt patterns, etc., are correct.
Surface Quality: The rim’s surface should be smooth, free from cracks or defects. Surface treatments such as polishing, sandblasting, or coating should meet appearance and performance requirements.
rim Holes: Ensure the rim holes (used for mounting tire bolts) are accurate, uniform, and have the correct diameter and thread.
Dynamic Balancing: rims must undergo dynamic balancing during the manufacturing process to ensure even weight distribution, preventing vibration and instability during rotation.
Heat Treatment: Some rims may require heat treatment to enhance strength and durability. Ensure the heat treatment process complies with standards.
Inspection and Quality Control: Conduct rigorous inspections and quality control, including dimension measurements, material testing, and surface quality checks.
Threads and Nuts: If there are threads on the rim, ensure they match with the nuts and have the correct torque specifications.
Regular Maintenance: Perform regular maintenance and inspections on the rims to ensure their safety and performance during use.
CNC machining of automotive rims requires high precision and quality control to ensure their reliability and safety on vehicles. Adhering to relevant standards and best practices is crucial in this process.
The forging and forming process of wheel rim mainly includes the following steps: winding, welding, flaring, rolling, expanding finishing, other processing, and pressing welding. In the winding stage, the steel plate is rolled into a cylinder by an automatic reclaiming machine and a winding machine. In the welding stage, the opening position is welded by flash butt welding technology, and the closed cylindrical object is obtained by flattening process and welding treatment. In the flaring stage, both ends of the rim are expanded into a flared shape by the flaring machine to ensure the reliability of workpiece positioning in rolling forming. In the rolling stage, the rim is rolled 3 times through the rolling mold to ensure that the coaxiality, cylindricity and size meet the requirements. Expansion finishing process through cold rolling deburring and circular correction, the rim diameter meets the design requirements. Finally, the press fit welding presses the spoke into the rim, and then the rim and spoke welding machine is used to weld the two parts into a single structure. The whole forging and forming process has the characteristics of high efficiency, energy saving and good quality. English translation.
