Autoclave-based creep age forming flexible frock

Abstract

The invention discloses an autoclave-based creep age forming flexible frock, which comprises a vacuum bag, a bottom plate, a high frame, a low frame, nail battens, four gaskets, an adjusting stud, a fixed plate and an air exhaust hose, wherein the bottom plate is provided with a pin hole and a threaded hole; the high frame has a frame body consisting of two short high frames and two long high frames, and the vacuum bag is covered on the high frame and a piece to be formed; the low frame has a frame body consisting of two short low frames and two long low frames, the high frame is fixed at the periphery of the low frame, and both the high frame and the low frame are fixed on the bottom plate; the nail battens are arranged on the bottom plate in parallel and fixed in the frame body of the low frame through side bolts; the four gaskets are arranged between the inner wall of the low frame and the nail battens; the lower part of the adjusting stud taps the screw thread which is used for forming the fixed plate with a screw thread pair; the central position of the fixed plate taps the screw thread hole which is used for forming the screw thread pair with the adjusting stud, the adjusting stud is fixed on the fixed plate, and then the fixed plate and the adjusting stud are fixed on the nail battens; and the air exhaust hose is connected to an air exhaust tube nozzle which penetrates and is fixed on the corresponding hole of the bottom plate and is hermetically connected through a silicon rubber gasket.

Description

(1) Technical field [0001] The invention relates to a flexible tooling for creep aging forming based on an autoclave, which is used for solidification molding of composite materials or creep aging forming of aluminum alloy wall panels and skin parts based on an autoclave, and belongs to the field of aviation manufacturing engineering. (2) Background technology [0002] Creep aging forming is a new technology developed in the early 1950s for forming composite materials, aluminum alloy integral wall panels, and skin parts. [0003] Early creep aging forming tooling often used welded clamping tools. In 2003, Airbus developed an adjustable clamping tool based on the original clamping tooling. [0004] When using this kind of clamp-type tooling for creep aging forming, a set of tooling is only suitable for forming one or a few parts. Due to the thousands of external panels and skin parts of various types of aircraft, the number of tooling is huge, and the processing cost It is h...

Problems solved by technology

[0005] The purpose of the present invention is to provide a flexible tooling for creep aging forming based on autoclave, so as to solve the defects existing in the existing pallet type tooling

Its forming force comes from the pressure difference inside and outside the vacuum bag
