[0021] The main chemical element content (percentage by weight) of the 2024 aluminum-based composite material is: Mn content 0.56%, Si content 0.065%, Cr content 0.0026%, Ti content 4.14%, Cu content 4.00%, Fe content 0.019% %, B content is 1.94%, Mg content is 1.52%, Zr content is 0.014%, and the balance is Al.
[0022] The steps of this method are as follows:
[0023] Take a blank of 2024 aluminum-based composite material of a certain specification, put it into an electric furnace, heat it to 420°C, and keep it warm for 270 minutes;
[0024] Take out the billet after heat preservation, upsetting on the free forging hammer, and then elongate; control the left end of the billet to remain unchanged, divide and elongate the blank at a distance from the left end of the billet, and then flatten the billet as a whole, as shown in 1 ; Then the left end of the blank is drawn and shaped to make a middle blank, as shown in 2;
[0025] Return the intermediate billet to the furnace and...
