Abstract

The invention and relates to a self-generating chilling method, in particular to a self-generating chilling method for controlling deformation of large complex aluminum copper alloy, and belongs to the field of machinery. Through the self-generating chilling method, the problem that according to an existing large complex aluminum copper alloy component, a casting is deformed during casting forming is solved. The self-generating chilling method has the specific steps that 1, part of a large complex aluminum copper alloy casting is divided into an A area and a B area, and whether self-generating chill blocks are suitable for being used in the A area and the B area is judged; 2, the number of the needed self-generating chill blocks is calculated; 3, the self-generating chill blocks are arranged in the corresponding areas; and 4, cavity positions of the self-generating chill blocks are formed.

Description

technical field [0001] The invention relates to a self-generated chilling method, in particular to a self-generated chilling method for controlling the deformation of a large complex aluminum-copper alloy, and belongs to the field of machinery. Background technique [0002] Large and complex aluminum-copper alloy components are widely used in aviation and aerospace military industries. Its processing and manufacturing process involves casting, heat treatment and other thermal processing processes, among which casting is the key link of forming components. For large and complex aluminum-copper alloy components, due to the complexity of its shape and structure, such as uneven wall thickness, a large number of auxiliary walls, reinforcing ribs, etc., deformation is very easy to occur during the casting process, and deformation out of tolerance will lead to scrapping of parts. Although a lot of research has been done on the casting deformation of large complex aluminum-copper a...
