What are the tasks to be done in the production of aluminum alloy wheels

After the finished product of the aluminum alloy wheel is oxidized, a special cast rod is used. After forging and heat treatment, the tensile strength reaches 570MPa, the yield strength reaches 540MPa, and the elongation is 15%. Compared with the wheel of the same specification, The weight can be reduced to 17.2kg, which greatly reduces the weight. The product has been oxidized, which effectively solves the problem of easy oxidation of aluminum alloy wheels and can meet the requirements of existing wheels. Compared with traditional steel wheels, aluminum alloy wheels have the advantages of light weight, beautiful appearance, and good cooling performance. Under the existing common forging methods, their good mechanical properties can only reach a tensile strength of 350mpa and a yield strength of 320mpa. The rate is about 12%. Forging: The front surface of the cast rod is pre-forged with a press forging machine, forged into a bowl shape, and then the back of the cast rod is forged once to be forged into a cylinder, and the rod is rolled into a forging billet with a spinning machine, and the shape of the forging billet is the hub edge.

Heat treatment: solution treatment of forged blank, solution temperature 465-475 ℃, solution time 2-3 hours, quenching within 15 seconds after solution treatment, quenching temperature 40-60 ℃, time 85-95 seconds, aging treatment after quenching , aging temperature 115-125 ℃, aging time 22-24 hours.
