[0002] Aluminum alloy forgings are common structural parts, and the manufacturing process of the existing aluminum alloy forgings is as follows: the aluminum alloy blank and the die are heated to a certain temperature and then are kept warm; after the aluminum alloy blank and the die reach the required temperature, the forging is further formed by using a press to form the corresponding forging. The aluminum alloy blank and the die are generally heated by a gas or electric furnace, and after the heating is completed, the blank is sent to the forging platform for forging production. However, as the use time increases, the temperature of the die gradually decreases, and when the temperature decreases to a certain temperature, the die must be reheated, thereby affecting the quality and production efficiency of the forgings. In addition, after the aluminum alloy blank is heated, it is usually sent to the die of the forging platform, and during the transfer process, the outer surface of the blank cools down a lot, resulting in poor stability of the forging quality.
