The world's automotive industry is developing in the direction of light weight, high speed, safety, energy saving, comfort and light environmental pollution, and the consumption of automotive aluminum alloy parts is increasing day by day.
As one of the important components of the automobile drive system, the wheel is also a kind of component with high safety requirements. It not only carries the weight of the automobile, but also reflects the appearance of the automobile. In the past 10 years, the average annual growth rate of global aluminum alloy wheel production has been 7.6%.
With the increasing demand for lightweight automobiles, aluminum alloy wheels are gradually replacing traditional steel wheels and are widely promoted and used in the modern automobile manufacturing industry. It is usually produced by casting or die-casting. Traditional casting methods include differential pressure casting, low pressure casting and gravity casting. Due to the pressure-filled high-speed turbulent movement of the alloy liquid, the gas cannot be discharged in the cavity, resulting in the product blank organization structure is not dense.
Compared with the traditional round rod cutting process, the method of upsetting the prefabricated billet can reduce the process of upsetting the round rod and the prefabricated billet in the conventional forging of aluminum alloy wheels, reduce the production process, reduce energy consumption, and improve production efficiency.
