A form-plate mechanically loaded creep aging forming device

Abstract

The invention discloses a forming plate type mechanical load creep age-forming device, which comprises a bottom plate, an upper plate, loading bolts, forming plates, supporting posts and lathings. The device has a compact structure and a reasonable conception; and during load, target parts are arranged on upper end faces of a plurality of forming plates, and a plurality of loading bolts are screwed, so that a piece to be formed is completely adhered to the upper end faces of the plurality of forming plates. The supporting pins are used for positioning vertical directions of the forming plate and adjusting the heights of the forming plates, so that the piece to be formed is roughly shaped due to resilience deformation. Due to guide grooves, the forming plates are convenient to mount and easy to replace, and forming requirements of various parts can be met. The forming device is suitable for parts with complex-curvature curved surfaces and conventional single-curvature parts, and has simple structure, low production cost and short production cycle.

Description

technical field [0001] The invention relates to a form-plate type mechanically loaded creep aging forming device, which 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, is mainly based on the characteristics that some metal materials will undergo stress relaxation at high temperature and can be age-strengthened at a certain temperature. The forming is combined into one to realize the integrated processing of the parts to be formed. In order to realize creep aging forming, it is first necessary to apply a certain initial load to the part to be formed to cause elastic deformation of a certain shape, and then maintain this deformation and place it at a constant temperature for a period of time to allow it to undergo creep aging, so that the part The elastic deformation is converted into plastic deformation, and the part to be formed is stre...
