Problems solved by technology

The single forming amount of this method is obviously greater than that of the press bending and shot blasting composite forming methods, but the overall strength of the formed parts may be reduced due to long-term high-temperature aging

Embodiment Construction

[0028] The present invention is specifically described below in conjunction with accompanying drawing and embodiment:

[0029] When the wall panel is bent and formed, the hard-to-deform area often corresponds to the local area where the elastic potential energy is relatively concentrated, and a moving point heat source with a certain intensity is introduced into this area in a certain way and path in a timely manner, and the deformation resistance of the material is reduced by building a local temperature field. And enhance its plastic deformation ability, promote the conversion of elastic potential energy into plastic deformation work, thereby improving the forming ability and forming accuracy of parts. The method can be divided into two working schemes: shaping and fine-tuning. The so-called forming scheme is to input a point heat source energy to the difficult-to-deform part of the part while forming by pressing or rolling. When this method is used for forming, the thermal...

Abstract

The invention discloses an integral wall plate digitization forming technique based on a bending and moving point heat source composite technique; processed parameters are solved and optimized after the emulation processing course implemented in computer platform and specialist system; an integral wall plate is fixed on the surface of a caul or a block plate by a block device with a force sensor and is implemented heat process by point heat source; when the display value of the force sensor lowers to a certain extent; the loading of the point heat source is stopped; according to the processing requirement, the processing course can have one or a plurality of increment forming. The invention has the advantages of huge process accuracy, non-loss, simple and easy operation.

Description

technical field [0001] The invention relates to the forming process of the integral wall panel. The integral wall panel is a sheet metal structural part integrating the supporting ribs and the skin. The invention especially relates to the difficult-to-form integral wall panel with large size, high ribs, and complex shape and structure. Digital forming manufacturing technology based on composite process of bending and moving point heat source. Background technique [0002] There is such a kind of sheet metal parts in engineering, such as the overall wall panel parts of the aircraft, which are the integrated components of the skin and the supporting ribs, which need to be bent (including roll bending: another form of bending, the formed parts can be While being bent, it is formed by rotating with the support roller). In order to ensure the safety of forming and meet the requirements of forming quantity and shape accuracy, such parts often need to be formed by a small amount o...
