Spinning forming method for complex thin-wall variable-cross-section component of aluminum alloy splice plate

Abstract

According to a spinning forming method for a complex thin-wall variable-cross-section component of an aluminum alloy splice plate, the aluminum alloy splice plate serves as a blank, the high-quality aluminum alloy thin-wall variable-cross-section component is manufactured in a spinning mode, and a feasible way is provided for breaking through limitation of ultra-wide plates and meeting the forming and manufacturing requirements of large or ultra-large thin-wall variable-cross-section components. Through eight-pass spinning machining, repeated material rolling and incremental forming, springback of the splice plate in the forming process is effectively reduced, the defects of poor surface quality caused by uneven materials, poor molded surface precision caused by large non-mold-attaching degree and the like can be effectively overcome, and the surface quality and molded surface precision of the component are greatly improved. The method is beneficial to recovering and remanufacturing of factory leftover materials, the production cost, resource waste and environmental pollution are reduced, and the method is convenient to popularize and apply.

Description

technical field [0001] The invention relates to the technical field of spinning forming, in particular to a spinning forming method of complex thin-wall variable-section components of aluminum alloy splicing plates. Background technique [0002] Spinning is an advanced plastic forming manufacturing technology, which realizes the forming and manufacturing of thin-walled rotary components by means of approximate local point loading of the blank by the spinning wheel. Because of the advantages of no metal cutting in the spinning forming process, high material utilization rate and almost no reprocessing of the final formed component, low equipment requirements, high production efficiency, good process flexibility and low forming load, it is widely used in aviation, aerospace, navigation, Widely used in weapons, automobiles, construction machinery and other industries. The spinning forming of the spliced ​​plate, because it adopts the welding process to obtain the forming blank,...
