Abstract

The invention relates to a variable-speed liquid filling-ultrasonic-laser composite forming method and system for a thin-wall component, which is used for forming a metal or composite material ultra-deep cavity complex feature component, forming an ultra-deep cavity feature by utilizing an ultrasonic vibration coupling passive liquid filling forming technology, and forming a complex small feature by utilizing a laser coupling high-speed liquid filling forming technology. According to the method, the forming limit, the forming quality and the complexity of the thin-wall component can be effectively improved, and the defects of cracking, wrinkling and the like in the forming process are reduced. The method has wide application prospects in the high-speed carrying fields of aerospace, automobiles and the like, especially in the aspect of integrated forming of ultra-deep-cavity thin-wall components with multiple complex characteristics, the forming performance of the plate is greatly improved, the blank in the forming field of the ultra-deep-cavity components is filled, the complexity of the formed components is widened, and the forming quality is improved.

Description

technical field [0001] The invention belongs to the technical field of sheet metal or composite material forming, and in particular relates to a variable-speed liquid-filling-ultrasonic-laser composite forming method and system for an ultra-deep cavity complex thin-walled component. Background technique [0002] With the development of society and technology, especially the development of high-speed transportation fields such as aerospace and automobiles in recent years, the demand for complex thin-walled components with ultra-deep cavities is becoming more and more urgent. Typical components with small features coupled with ultra-deep cavity features are difficult to form, and the existing technology is difficult to reach the required forming limit, and the forming quality is not up to standard. [0003] There are two main problems in the precise forming of metal or composite ultra-deep cavity complex thin-walled components: one is that problems such as cracking and wrinkli...
