The world's automobile industry is developing in the direction of lightweight, high speed, safety, energy saving, comfort and light environmental pollution. The consumption of automotive aluminum alloy parts is increasing. Next, the editor will take you to understand aluminum alloy The forging forming method of the wheel hub. As one of the important parts of the car drive system, the wheel is also a part with high safety requirements. It not only bears the weight of the car, but also reflects the appearance of the car. In the past 10 years, the global aluminum alloy wheel production has grown on average every year The rate is 7.6%. With the increasing demand for lightweight automobiles, aluminum alloy wheels are gradually replacing traditional steel wheels and have been widely promoted and applied in modern automobile manufacturing. They are usually produced by casting or die-casting methods. Traditional casting methods There are differential pressure casting, low pressure casting and gravity casting. Due to the pressurized high-speed turbulent movement of the alloy liquid, the gas cannot be discharged in the cavity, resulting in a non-dense structure of the product blank.
Compared with the traditional round bar cutting process, the method of upsetting the preform can reduce the round bar upsetting and preform process in the conventional forging of aluminum alloy wheels, reduce the production process, reduce energy consumption, and improve production efficiency.
