An electro-hydraulic-electromagnetic composite forming system and forming method

Abstract

The invention discloses an electro-hydraulic-electromagnetic composite forming system, belonging to the field of metal forming manufacturing, comprising: a metal pipe fitting to be formed, which is placed in a mold with both ends closed, and a liquid medium is stored therein; a metal wire is immersed in the liquid medium Middle; the first power supply module is connected with the metal, and is used to discharge the metal wire to generate shock waves in the metal pipe; the two booster coils are respectively arranged at the top and bottom of the metal pipe; the second power supply module and the two booster coils Both are connected and used to discharge the two booster coils to generate a booster electromagnetic force in the metal pipe; the discharge control module is connected to the two second power supply modules to control the discharge timing of the two power supply modules, so that the shock wave and the Under the synergistic effect of boosting electromagnetic force, the plastic deformation processing of metal pipe fittings is realized. The invention can effectively solve the problems of workpiece thinning, cracking and the like caused by poor material fluidity in the existing electro-hydraulic forming technology, and improve the molding performance of the workpiece.

Description

technical field [0001] The invention belongs to the field of metal forming and manufacturing, and more specifically relates to an electro-hydraulic-electromagnetic composite forming system and a forming method. Background technique [0002] Lightweight aluminum alloy materials are widely used in automobile manufacturing, aerospace and other fields due to their superior mechanical properties. However, the effect of plastic processing of aluminum alloy by traditional processing technology is not ideal, which is mainly due to the poor plasticity and difficulty of forming aluminum alloy. [0003] Studies have shown that high-speed forming can significantly improve the formability of materials. Electro-hydraulic forming is a manufacturing technology that uses shock waves generated by metal wire explosions to process workpieces. It belongs to high-speed forming and can greatly improve the forming performance of materials. However, in the process of electro-hydraulic forming, due...
