Shock hydraulic composite forming process for small feature part of complex part

InactiveCN102873165AGuarantee the overall forming quality and precisionBroad application prospects
The invention discloses a shock hydraulic composite forming process for a small feature part of a complex part. The shock hydraulic composite forming process is a new forming process which intersects with a shock forming technology and a hydroforming technology and extends and develops from both of the two technologies, having advantages of both of hydro plastic forming and shock energy forming. The shock hydraulic composite forming process is defined as follows: performing the shock forming after the hydroforming is finished, utilizing momentarily released high energy of a shock source to compress high pressure liquid in a forming liquid room to obtain a surged pressure value which is transmitted to formed blanks in form of shock waves, so as to perform the new manufacturing process of elasticoplastic deformation of the part. Due to one-step installation, processing procedure is reduced, which helps to realize monolithic forming of a complex large curved surface part and guarantees positional accuracy of complex parts with various sizes. Meanwhile, the shock time is very short, which reduces requirements in terms of intensity and tightness of the device. The shock hydraulic composite forming process has a wide application prospect in fields such as aeronautics and astronautics, and automobile in aspects of forming, reforming and the like of large complex components with small feature sizes such as small convex hull, small pressing mark, and small holes.
