Problems solved by technology
However, for some metal shells with complex structures, they cannot be produced by traditional one-time die-casting methods.
This kind of metal shell is generally made by joining two or more workpieces together by friction stir welding, but the metal shell formed by friction stir welding often has welding defects such as excessive material deformation at the weld. , which seriously affects the overall appearance of the metal shell

Abstract
The invention discloses a method for manufacturing a metal shell. The method comprises the following steps of: providing a first workpiece and a second workpiece which are made of metal, wherein the first workpiece comprises a supporting surface, the second workpiece comprises a joint surface, and outer surface layers of joints of the first workpiece and the second workpiece are respectively made of an aluminum alloy material; attaching the joint surface of the second workpiece to the supporting surface of the first workpiece; welding the first workpiece and the second workpiece to form a metal shell by a friction stir welding method, wherein the diameter of a shaft shoulder of a stirring head used in the friction stir welding method is 8 to 15mm; and performing anodic oxidation treatment on the metal shell. By performing anodic oxidation treatment, the whole metal shell has relatively attractive appearance; the diameter of the shaft shoulder is 8 to 15mm, so that color of a welding region subjected to anodic oxidation treatment and the color of the surrounding materials are substantially consistent, and the overall appearance quality of the metal shell is further improved.
Description
technical field [0001] The invention relates to a method for manufacturing a metal shell. Background technique [0002] As consumers' requirements for electronic products continue to increase, some electronic devices begin to use metal casings. For some metal shells with relatively simple structures, they are usually made by die-casting. However, for some metal shells with relatively complex structures, they cannot be produced by traditional one-time die-casting methods. This kind of metal shell is generally made by joining two or more workpieces together by friction stir welding, but the metal shell formed by friction stir welding often has welding defects such as excessive material deformation at the weld. , and then seriously affect the overall appearance of the metal shell. Contents of the invention [0003] In view of the above situation, it is necessary to provide a method for manufacturing a metal shell that can improve the appearance quality of the product. [...
