Problems solved by technology

The shell prepared by die-casting can obtain more complex structural features, but its mechanical properties are relatively poor, especially the plasticity; and after die-casting, the internal structure of the material is seriously segregated, and the effect of subsequent anodic oxidation treatment is poor, which leads to the apparent effect Difference
The shell prepared by the stamping method has less internal structure segregation, and the effect of subsequent anodic oxidation is good, and a good appearance effect can be obtained, but the product shell is mainly formed by stretching, bending, etc., and the product cross-section The thickness is consistent, so products with complex structural features cannot be formed

preparation example Construction

[0013] The invention provides a method for preparing an aluminum alloy shell, which comprises the following steps:

[0014] S110, blanking: cutting the aluminum alloy billet into a preset size to obtain a blanking piece.

[0015] For example, a shearing machine is used to cut an aluminum alloy billet into a required size to obtain a blank. That is, under the action of the blade of the shearing machine, the aluminum alloy billet produces bending and tensile deformation, and when the stress exceeds the shear strength, it breaks to form a billet of a certain size, and the blank is obtained. For example, the aluminum alloy blank in the present invention is a 6-series aluminum alloy, such as aluminum alloys with models 6061, 6063, and 6463.

[0016] S120, solution treatment: performing solution treatment on the blanked parts to obtain solution treated parts.

[0017] The solution treatment (Solution treatment) refers to a heat treatment process in which the alloy is heated to a h...

Embodiment 1

[0036] Cutting: cutting the 6-series aluminum alloy billet into a preset size to obtain the blanking parts;

[0037] Solution treatment: place the blanking part at a temperature of 530° C. for 90 minutes, and then cool it with cold water to obtain a solution treatment part;

[0038] Lubrication treatment: performing lubrication treatment on the solid solution treatment piece;

[0039] Forging and forming: After the solution treated part is cold forged twice, trimming and / or cutting holes are performed, and then cold forging is performed to obtain a forging formed part;

[0040] Aging treatment: place the forged and pressed parts at 175°C for 8 hours;

[0041] Finishing: CNC is used to finish the aluminum alloy shell;

[0042] Anodizing treatment: Anodizing the finished workpiece.

Embodiment 2

[0044] Cutting: cutting the 6-series aluminum alloy billet into a preset size to obtain the blanking parts;

[0045] Solution treatment: the blanking parts were kept at a temperature of 535°C for 90 minutes, and then cooled with cold water to obtain solid solution treatment parts;

[0046] Lubrication treatment: performing lubrication treatment on the solid solution treatment piece;

[0047] Forging and forming: After the solution treated part is cold forged twice, trimming and / or hole cutting is performed, and then cold forging is performed twice to obtain a forging formed part;

[0048] Aging treatment: place the forged and pressed parts at 180°C for 8 hours;

[0049] Finishing: use CNC to finish the workpiece after aging treatment;

[0050] Anodic oxidation treatment: anodic oxidation treatment is performed on the finished workpiece.
