Flexible processing method of ribbed thin-wall large-sized aluminum alloy cylinder

Abstract

The invention provides a flexible processing method of a ribbed thin-wall large-sized aluminum alloy cylinder. According to the method and through the technical processes of punching cylindrical aluminum alloy billets, performing ring rolling, performing axial extrusion, dividing a unit body, performing welding integration and the like, flexible batched production of a series of ribbed thin-wall large-sized aluminum alloy cylinder structural pieces with different diameter can be realized. According to the method, the process, with large rib part machining quanity and long processing cycle, of the thin-wall large-sized aluminum alloy cylinder structural piece in the past is changed, the production efficiency and the stability of the cylindrical pieces are greatly improved, and the manufacturing cost and the development cycle are reduced.

Description

technical field [0001] The invention belongs to the technical field of processing a large thin-walled aluminum alloy cylinder with ribs, and in particular relates to a flexible processing method for a large thin-walled aluminum alloy cylinder with ribs. Background technique [0002] Thin-walled large aluminum alloy cylinders with ribs are widely used in the structures of various types of space vehicles. At the same time, space vehicles have different thrusts and different design requirements, so the structure with ribs and the spacing between the ribs are also different. There are a large number of thin-walled tube structures with ribs of different specifications and sizes in the large-scale structure of the tool. The size of these ribbed thin-walled tube structures is close to the limit size, for example, the wall thickness is about 2 mm, and the rib height is about 50 mm, which has become a difficult problem in the design and manufacture of vehicles, and often becomes a ke...

AI Technical Summary

Problems solved by technology

The design process at this stage is generally to design different rib structures according to the use requirements, then manufacture thick-walled plates, and then remove the remaining material through a large number of machining, and finally form thin-walled tubes with ribs. The machining during this period is time-consuming. At the same time, it will cause problems such as deformation of the overall structure, so it is necessary to invest a lot of manpower and financial resources to ensure the structural quality of the thin-walled tube with ribs
