Complex double-curvature creep aging forming device

Abstract

The invention relates to a complex double-curvature creep aging forming device, wherein a thinking design of adjustable longitudinally-symmetrical multipoint bending deformation is adopted so that the complex single / double-curvature creep aging forming of a ribbed wallboard can be conveniently and easily realized. The complex double-curvature creep aging forming device provided by the invention mainly comprises an upper bracket 5, a lower bracket 12, a pressing plate 6, a guide plate 7, a compression bar 8, support bar 10, a double-head stud 1, four hexagon nuts 3, a flat washer 4, a hexagon bolt 2 and a lower connecting plate 11, wherein wallboards with different shapes and thicknesses are placed at a sample wallboard 9; the symmetrically-arranged hexagon nuts 3 are rotated to passes through the pressing plate 6 and the guide plate 7; load is applied to the wallboard 9 through the compression bar 8 arranged on the guide plate; and four adjustable symmetrically-arranged support bars 10 are arranged below the wallboard to ensure that the wallboard is deformed and various different initial curvature shapes of the wallboard 9 can be obtained through adjusting the positions of the compression bar 8 and the support bar 10 and the different fastening degrees of the hexagon nuts. According to the complex double-curvature creep aging forming device disclosed by the invention, the design of adjustable loading and supporting positions is adopted and suitable for the single / double-curvature bending deformation of a complex ribbed wallboard. Compared with a conventional device, the device provided by the invention has the advantages of simple and reliable structure and convenience for operation and is suitable for various heating devices.

Description

Technical field: [0001] The invention relates to an aging forming device, in particular to a forming device for complex single- and double-curvature wall plates with ribs, and belongs to the field of aviation manufacturing engineering. Background technique: [0002] Creep age-forming (CAF), generally referred to as time-effect stress relaxation forming in China, mainly utilizes some metal materials (such as high-strength aluminum alloys) to undergo creep / stress relaxation at high temperature and age-strengthened at a certain temperature. Features, the heat treatment and forming process are combined into one, so as to realize the integrated manufacturing of component forming. Firstly, an initial load is applied to the workpiece to cause elastic deformation of a certain shape, and then the deformation is maintained and placed in a constant temperature furnace for aging for a period of time (for high-strength aluminum alloys, generally 24-48 hours), so that it can creep and mak...
