Abstract
Description
Technical field:
[0001] The invention relates to a solid state hot extrusion forming device for a magnesium alloy wheel hub and a forming method thereof. Background technique:
[0002] Due to the increasingly serious energy crisis and the worsening air pollution, countries all over the world have higher and higher requirements for energy conservation and environmental protection. Engine exhaust from vehicles and other vehicles has become the number one killer of air pollution. According to statistics, for every 100kg reduction in vehicle weight, the fuel consumption per 100 kilometers is reduced by 0.7 liters, and every 10% reduction in vehicle weight, fuel efficiency can also be increased by 5.5%. Therefore, reducing the weight of vehicles is an effective way to reduce energy consumption and purify the air. Even for vehicles such as electric vehicles that do not emit exhaust gas, reducing weight is an effective way to save energy consumption. Compared with steel, aluminum alloy ...
