Abstract:

We investigated the effects of primary system parameters on the magnetic pulse sizing of aluminum tubes. Furthermore, we present the applicable design method of the sizing coils required for tube sizing. For the AA5056-O tube, we utilized the method of three-section sizing, with one coil for the corresponding position and three times discharge. The research results indicate that the length of the solenoid coil is inversely proportional to the nominal peak value of magnetic pressure; the appropriate combination of the discharge voltage and the gap between the tube and die dictates the sizing; the sizing precision can be improved greatly by iterative sizing, and three times is optimal. The experimental results of magnetic pulse tube sizing meet the technical requirements.
