AI Technical Summary

Problems solved by technology

Since the spinning blank is produced by different die-casting molds, the positioning inner diameter of the spinning blank will be inconsistent, resulting in inaccurate positioning; and with the wear of the die-casting mold during the production process, the positioning inner diameter of the spinning blank will also change

Description

technical field [0001] The invention relates to a mold for spinning and forming an aluminum alloy wheel rim, which belongs to the field of aluminum and aluminum alloy wheel processing and manufacturing. Background technique [0002] With the rapid development of the automobile industry, the major automobile factories in the international market have higher and higher requirements for automobiles: safety, comfort, energy saving, aesthetics, low noise, and low pollutant emissions have become the development trend of the automobile industry in the future. As an important part of the car, the wheel is an important part to achieve the requirements of vehicle safety, comfort, energy saving, aesthetics, and low noise. Aluminum alloy wheels are more and more used in automobiles due to their superior material properties, light weight, good heat dissipation, and rich and beautiful appearance. At present, aluminum alloy wheels are developing in the direction of large diameter, light w...
