The production of automobile wheel hub should pay attention to technology

Car hubs are in car tires, cylindrical metal parts used to support the axle as the center of the tire, that is, the axle is installed in the center of the wheel, they are important parts that connect brake drums or brake discs, wheels and axles, automobiles Wheels can be divided into steel wheels and alloy wheels according to their materials. Because steel wheels have ugly appearance, heavy weight, inertia resistance, and easy to rust, alloy wheels can make up for this problem, so automobile manufacturers are increasingly using alloy materials to manufacture automobile wheels. Cleaning and polishing: Clean the surface of the alloy blank after cutting with a tap water high-pressure spray gun, and perform mechanical polishing and carburizing treatment: the above steps clean and polish the alloy blank and put it into a carburizing furnace for carburizing treatment. The carburizing temperature is 880 ° C ~ 920 ° C ℃, carburizing time 90min~120min, tempering temperature 360℃~400℃, tempering time 50min~60min.

Due to the continuous increase in the use of automobiles and the extension of mileage, the hardness of automobiles is getting higher and higher, which improves the wear resistance and tensile strength of the wheels, and the alloy materials of the wheels cannot fully meet people's needs, resulting in easy damage to the wheels , Frequent replacement increases the maintenance cost of the car.
