High-deformation press forging forming process for A 5052-H32 aluminum alloy mobile phone shell with convex post

Abstract

The invention belongs to the field of stamping processes, and in particular relates to a high-deformation press forging forming process for a complex structural aluminum alloy mobile phone shell with a convex post and the like. A metal flowing law of a side wall with process defects and the convex post is obtained by three-dimensional simulation of the press forging process of a complex structural aluminum alloy piece based on a rigid plastic finite element method, and a metal flowing law of a side wall without process defects and the convex post is obtained by improving the structure of a die and by means of a velocity vector diagram in analog simulation, so that the technical problems of the complex structural aluminum alloy piece in press forging forming are solved, certain test links are avoided, the design and manufacturing period of a product is shortened, the production efficiency of the complex structural aluminum alloy piece is greatly improved, and the production cost is reduced.

Description

【Technical field】 [0001] The invention belongs to the field of stamping technology, and more specifically relates to a large-deformation cold stamping and forging forming process of an A5052-H32 aluminum alloy mobile phone shell with a convex column. 【Background technique】 [0002] In recent years, the housing of 3C electronic products has been influenced by the trend of lightweight, strong and beautiful design. Aluminum alloy has the advantages of light weight, high strength, high rigidity, diverse surface treatment methods and good thermal conductivity, so it is better than plastic and Magnesium alloy is more suitable for the housing of 3C products. [0003] At present, the manufacture of aluminum alloy mobile phone casings with convex column structure mainly includes the following processes: [0004] (1) Die-casting. This process can form mobile phone casings with complex structures and shapes such as convex posts and ribs, but the products have low production efficienc...

Problems solved by technology

In early studies, people made a lot of simplifications and assumptions when analyzing plastic processing problems for the convenience of solving, and these methods are only applicable to some simple forming processes; but for complex forming processes, there is a lack of a systematic and accurate Theoretical analysis methods affect the accuracy and reliability of the solution
