Electromagnetic forming device and forming method for aluminum alloy rib plate

Abstract

The invention discloses an electromagnetic forming device and a forming method for an aluminum alloy rib plate. The electromagnetic forming device is characterized in that a forming coil comprises two web coils and a rib coil, the web coils are used for forming webs of the rib plate, and the rib coil is used for forming ribs of the rib plate. The rib coil is fixedly sealed in a rib coil shell and then is serially connected into a rib coil discharge circuit. The two web coils are respectively used for forming the corresponding webs on two sides of each rib; the web coils and web coil shells are respectively fixedly and integrally sealed with one another, and the two web coils are connected into web coil discharge circuits in parallel. The forming coil is positioned above the rib plate. The forming method includes that interactive magnetic field force is generated among the coils in the pulse discharge circuits and the rib plate to be machined; the web coils continuously move in horizontal planes along certain tracks, and the rib plate can be incrementally machined by the aid of the magnetic field force generated by the two types of coils, finally is laminated on a mold and is formed accumulatively. The electromagnetic forming device and the forming method have the advantages of high forming speed, good mold lamination property of the rib plate and surface quality of a formed part, low forming rebounding and the like, and are applicable to machining large rib plates.

Description

technical field [0001] The invention relates to the field of ribbed material processing, in particular to a device and method for forming aluminum alloy ribbed components by using electromagnetic forming. It is mainly used for the precise forming of aluminum alloy ribs to solve the problems of difficult forming, poor forming quality or low forming efficiency of conventional forming techniques for ribs. Background technique [0002] Rib structural parts are aerospace and navigation fields, especially one of the most complex, difficult and critical parts in the manufacture of aircraft overall panels. An important sign of advanced level. For more than 30 years, aircraft manufacturing companies such as Boeing and Airbus have conducted a lot of research on the forming of ribs. Such components are generally made of materials with excellent performance but difficult to process, such as aluminum alloys, titanium alloys, etc., and have complex shape curves (single curvature or doub...
