Embodiment 1
[0036] Such as figure 1 As shown, a deep drawing forming production process of the slat slide rail sleeve comprises the following steps:
[0037] S1: Raw material ratio
[0038] According to the mass percentage Mg: 5.6%, Mn: 0.4%, Cr: 0.09%, Ti: 0.15%, and the balance is Al for batching. Mg, Mn, Cr, Ti, and Al are all powders with a particle size of 20-30 μm. The configured raw materials are put into the mixer for mixing, and the alloy powder is obtained after mixing;
[0039] S2: Metal Smelting
[0040] Put the alloy powder into a crucible for smelting, add graphene after the powder forms a melt, the volume ratio of graphene to the melt is 1:12, degas and remove slag from the melt to obtain a mixed melt, and mix the melt cast the body to obtain an aluminum alloy ingot;
[0041] S3: Quenching
[0042] The obtained aluminum alloy ingot was kept at 490°C for 5 minutes, and then oil-cooled and quenched. After repeated 3 times, the aluminum alloy ingot was heated to 450°C for...
Embodiment 2
[0058] Such as figure 1 As shown, a deep drawing forming production process of the slat slide rail sleeve comprises the following steps:
[0059] S1: Raw material ratio
[0060] According to the mass percentage Mg: 6.0%, Mn: 0.8%, Cr: 0.1%, Ti: 0.18%, and the balance is Al for batching. Mg, Mn, Cr, Ti, and Al all use powders with a particle size of 30-40 μm. The configured raw materials are put into the mixer for mixing, and the alloy powder is obtained after mixing;
[0061] S2: Metal Smelting
[0062] Put the alloy powder into a crucible for smelting, add graphene after the powder forms a melt, the volume ratio of graphene to the melt is 1:12, degas and remove slag from the melt to obtain a mixed melt, and mix the melt cast the body to obtain an aluminum alloy ingot;
[0063] S3: Quenching
[0064] The obtained aluminum alloy ingot was kept at 495°C for 6 minutes, and then oil-cooled and quenched. After repeated 4 times, the aluminum alloy ingot was heated to 455°C and ...
Embodiment 3
[0080] Such as figure 1 As shown, a deep drawing forming production process of the slat slide rail sleeve comprises the following steps:

[0082] According to the mass percentage Mg: 6.3%, Mn: 1.0%, Cr: 0.13%, Ti: 0.2%, and the balance is Al for batching. Mg, Mn, Cr, Ti, and Al are all powders with a particle size of 40-45 μm. The configured raw materials are put into the mixer for mixing, and the alloy powder is obtained after mixing;
[0083] S2: Metal Smelting
[0084] Put the alloy powder into a crucible for smelting, add graphene after the powder forms a melt, the volume ratio of graphene to the melt is 1:12, degas and remove slag from the melt to obtain a mixed melt, and mix the melt cast the body to obtain an aluminum alloy ingot;
[0085] S3: Quenching
[0086] The obtained aluminum alloy ingot was kept at 500°C for 8 minutes, and then oil-cooled and quenched. After repeated 5 times, the aluminum alloy ingot was heated to 460°C and ...
