[0002] With the rapid development of the times, advanced manufacturing industries such as machinery, vehicles, and aerospace have put forward more stringent requirements on product quality and performance. Under the premise of ensuring performance, optimizing product structure and adopting lightweight materials are of great significance to reducing costs and saving energy. Among them, precision and complex components are widely used as key connecting parts in the fields of aerospace, intelligent robots, etc., with extremely high requirements for performance and size. However, the existing traditional processing methods are difficult to meet their production needs. The development of multi-directional extrusion forming technology provides new research directions and ideas for processing such components.

[0003] Multi-directional extrusion one-step forming is a metal processing technology.
