Abstract：

In order to study the influence of temperature on the round hole flanging process for the quenched 2219 aluminum alloy sheet, the hot tensile tests of the quenched 2219 aluminum alloy sheet were performed in the temperatures range of 25-300 ℃ to study the change of its mechanical properties at different temperatures, and the round hole flanging test under the heating state was carried out according to the result of the hot tensile test. The results show that heating can improve the plasticity of the quenched 2219 aluminum alloy sheet, and the elongation reaches more than 40% when heated to 150 ℃. As the temperature increases, the elongation continues to increase, but when it exceeds 200 °C, the elongation decreases slightly as the temperature increases. Compared with the round hole flanging at room temperature (25 ℃) , heating can significantly improve the round hole flanging formability of the quenched 2219 aluminum alloy sheet, when the temperature is 170-180 ℃, the flanging round hole can be formed at one time, and heating does not affect the final mechanical properties of the product.
