Problems solved by technology

[0008] For the second process, if you want to get a fine sand effect, it is difficult to cover the defects of the aluminum material (such as friction lines, grinding marks) by sandblasting. If you want to cover them, you need to use larger grains of sand (such as 80 # of iron sand), but it is difficult to get a fine sandy surface

Embodiment 1

[0031] image 3 A schematic flow chart of an embodiment of the aluminum alloy processing method of the present invention is shown.

[0032] One embodiment of the present invention provides an aluminum alloy processing method, comprising:

[0033] In step S110, the first sandblasting treatment is performed on the aluminum alloy with multi-angular abrasives.

[0034] The first sandblasting treatment is performed on the aluminum alloy with multi-angular and strong abrasive abrasives. The multi-angular and strong abrasive can remove the defects on the surface of the aluminum alloy and achieve the effect of grinding, while avoiding the edge collapse caused by grinding. , deformation and other problems, improve the yield rate and reduce the cost.

[0035] Such as figure 2 As shown, by using multi-angular abrasive abrasives for sandblasting, there is no phenomenon such as edge sagging.

[0036] Sand blasting is the process of cleaning the surface of the substrate by the impact o...

Embodiment 2

[0055] Embodiment 2 provides a method for processing an aluminum alloy mobile phone casing.

[0056] First of all, the aluminum alloy mobile phone shell workpiece made of stamped aluminum or profile aluminum that does not need to be processed for the appearance surface is processed for related structures (no surface processing is involved), and the workpiece is stamped in turn (CNC is sometimes used to replace this step for profile aluminum), CNC Processing, pending surface treatment.

[0057] Secondly, carry out the sandblasting treatment for the first time to the aluminum alloy workpiece after CNC processing with multi-angular abrasive; utilize chemical method to remove described multi-angular abrasive on the surface of aluminum alloy workpiece; use zirconia to remove described multi-angular abrasive The surface of the aluminum alloy workpiece is subjected to the second sandblasting treatment. For the above process flow, reference may be made to the detailed description of ...

Abstract

An aluminum alloy machining method, an aluminum alloy shell and a mobile terminal are disclosed. The method includes subjecting an aluminum alloy to a first time of sand blasting by utilizing a multi-edge and multi-corner abrasive material; removing the abrasive material from the surface of the aluminum alloy by utilizing a chemical process; and subjecting the aluminum alloy from which the abrasive material is removed to a second time of sand blasting by utilizing zirconia. The aluminum alloy shell obtained by the method has finer sand sense, the yield is increased and the cost is reduced.

Description

technical field [0001] The invention relates to a metal processing technology, in particular to an aluminum alloy processing method, an aluminum alloy shell and a mobile terminal. Background technique [0002] Modern daily life has become more and more inseparable from electronic devices, such as tablet computers, smart phones, e-books, portable notebooks, etc. As people have higher and higher requirements for the appearance of electronic products, higher requirements are also put forward for the materials and processing technology of electronic product casings. [0003] Aluminum alloy is the most widely used non-ferrous metal structural material in industry, and has been widely used in aviation, aerospace, automobile, machinery manufacturing, shipbuilding and chemical industry. Due to the low density of aluminum alloy, but relatively high strength, which is close to or exceeds that of high-quality steel, it has good plasticity and can be processed into various profiles, so...
