Electronic product aluminum shell cold forging (cold heading) method and product thereof

Abstract

The invention discloses an electronic product aluminum shell cold forging (cold heading) method and a product thereof. The method comprises the following steps that (1), an aluminum board is prepared; (2), a cold forging mould carries out cold forging on the aluminum board and an aluminum shell blank in a needed shape is moulded; (3), the inner surface of the aluminum shell blank is machined; and (4), the outer surface of the aluminum shell blank is machined, and an electronic product aluminum shell product is obtained. The method is simple in process, the cold forging procedure replaces a pressure casting procedure and is easy to implement, the production period is greatly shortened, the production efficiency is high, and the cost is low. The structural density of the prepared product is large, the overall structural intensity is improved effectively, the heat conduction and heat dissipation properties are good, the comprehensive performance is good, and the application range is wide, for example, the electronic product aluminum shell cold forging (cold heading) method and the product thereof can be used for producing radiators, mechanical and electrical product end covers, communication cavities, USB flash disk cover bodies, fingerprint product cover bodies, cover bodies of other electronic products and the like.

Description

technical field [0001] The invention relates to the technical field of cold forging of aluminum shells, in particular to a method for cold forging (cold heading) of aluminum shells of electronic products and products thereof. Background technique [0002] With the continuous improvement of people's living standards, the styles of consumer products are becoming more and more diverse. They must not only have beautiful appearance and exquisite design, but also quickly meet market demand. At present, electronic products have generally adopted aluminum shell structure, because the aluminum shell has a good decorative effect. It is light in weight, and compared with plastic shells, its structural strength is better, and it is more and more favored by people. [0003] However, the existing electronic product aluminum shell production process is cumbersome, and mostly adopts the pressure casting process, that is, the aluminum part is to use the pressure casting mechanical die-castin...

AI Technical Summary

Problems solved by technology

[0003] However, the existing electronic product aluminum shell production process is cumbersome, and mostly adopts a pressure casting process, that is, the aluminum part is to use a pressure casting mechanical die-casting machine equipped with a casting mold, and the aluminum or aluminum alloy heated to a liquid state is poured into the die-casting machine. The material port is die-cast by a die-casting machine to cast aluminum parts or aluminum alloy parts of the shape and size limited by the mold, and then process the parts; due to the long working hours of the die-casting process, it has a long production cycle and low production efficiency , high production costs and other defects, which are not conducive to the development of enterprises
