Method for manufacturing aluminum alloy integral pan head

The manufacturing method of the aluminum alloy integral pan head is characterized by being realized through the following steps:

1. (1) Disc processing: heat the aluminum alloy material to 700-720°C for smelting, and pour the aluminum alloy melt into aluminum alloy round ingots for homogenization treatment: heat to 455-470°C and keep it warm for 24 hours ; After sawing, heat it to 410～430℃ and keep it for 2～4 hours, then carry out free forging and die forging treatment, and then carry out quenching. The quenching temperature is 469～475℃, the holding time is 120～150 minutes, and then artificial aging is carried out. Treatment, the artificial aging temperature is 138～145℃, the holding time is 18～22 hours, and the final processing is completed by a metal cutting machine;

(2) Coil processing: heat the aluminum alloy material to 700-720°C for smelting, pour the aluminum alloy melt into aluminum alloy ingots, and process the aluminum alloy ingots into coils by extrusion; In the argon arc welding method, two discs are welded to the two ends of the coil; third, the welded parts are subjected to surface oxidation treatment to obtain the pan head.
