Embodiment Construction

[0027] A creep aging forming tool for large complex curvature components, such as figure 1 As shown, it mainly includes mold surface 4, positioning structure 6, reinforcement structure 5, clamping plate 1 and auxiliary structure. The mold surface consists of a complex curvature forming surface in the middle and platforms at both ends. The complex curvature forming surface is 15-20mm thick, which is the forming surface for the final bending and bonding of components, and the two ends of the platform are used to stick vacuum bags. The positioning structure includes a positioning column and a fixing block, and preferably also includes a positioning line drawn on the surface of the mold, so that the component is bent downward and finally fits the mold and is located in the target area. The reinforcement structure 5 is welded by two longitudinal U-shaped steels, and its main function is to increase the strength and rigidity of the mold during lifting and transportation. Clamp 1 is...

Abstract

The invention provides a vacuum creep age forming device for a complex-curvature aluminum alloy component. The vacuum creep age forming device for the complex-curvature aluminum alloy component comprises a complex curvature containing die profile and a positioning structure arranged on the die profile. The die profile is provided with through holes. The positioning structure comprises fixing blocks which are correspondingly welded to the through holes and cylindrical positioning columns arranged in the fixing blocks. The fixing blocks are provided with cylindrical blind holes for the positioning columns to be inserted. The material strength of the positioning structure is larger than that of the die profile, and the perimeter zone for forming a raw material aluminum alloy plate is providedwith two kidney-shaped through holes for the two positioning columns to be inserted. By means of the device, an aluminum alloy component can be completely attached to a forming target zone on the dieprofile, and precise manufacturing of the component is achieved.

Description

technical field [0001] The invention relates to the technical field of precise forming and manufacturing of large complex curvature thin-walled aluminum alloy components, in particular to a device for vacuum creep aging forming of large thin-walled components with complex large curvature and high forming stress characteristics for aerospace. Background technique [0002] Creep aging forming is a new type of sheet metal forming method developed to realize the precise forming and high-performance collaborative manufacturing of large-scale overall high-strength aluminum alloy components for aerospace. It has the advantages of high forming accuracy, low cost, high repetition rate, and residual Low stress and other advantages. At present, this technology is mainly used in the forming and manufacturing of components with small curvature and low forming stress characteristics, such as the upper skin of aircraft wings. Due to the large radius of curvature of this type of component,...
