Investigation on the Innovative Impact Hydroforming Technology
Hydroforming has a rapid development recently which has good forming quality and less cost.However,it still cannot meet the requirements of forming complex parts with small features just like convex tables,or bars which are widely employed in automotive and aircraft industries.The impact hydroforming technology means the most features are formed by hydroforming and the small features are rapidly reshaped by high intensity impact energy in a very short time after the traditional hydroforming.The impact pressure rises to the peak in 10ms which belongs to dynamic loading.In this paper,impact hydroforming process is proposed.The generation and transmission of impact hydroforming energy and impact shock wave were studied and simulated.The deformation process of the metal disks under the dynamic impact loading condition presented impact hydroforming is an effective technology to form complex parts with small features.
