摘要:

 提出管件磁脉冲冲击弹性介质成形技术,研究了放电能量、成形温度、复合成形等对5A02铝合金管件成形的影响规律。室温下,管件的变形程度随着放电能量的增加而增加(放电能量为7 kJ时,膨胀率为24%,壁厚减薄率为22%),并且最大变形位置随着放电能量的增加逐渐向中心靠近(放电能量为7 kJ时,最大变形位置位于中心区域)。当放电能量一定时,调节成形温度(25~150 ℃),变形管件的最大直径无明显变化,表明在磁脉冲冲击高速率成形过程中,成形温度在25~150 ℃范围内对5A02铝合金管件的变形影响较弱。探究了室温磁脉冲冲击弹性介质预变形与准静态成形(成形温度为100和150 ℃)的复合成形对5A02铝合金管件成形的影响,结果表明,复合成形较单独的准静态成形和磁脉冲冲击弹性介质成形更易于使管件获得更大的变形程度以填充模具。

 Magnetic pulse impacting elastic medium forming technology of tube was proposed, and the influence laws of discharge energy, forming temperature and compound forming etc. on the tube deformation were investigated. Then, at room temperature, the deformation degree of tube increases with the increasing of discharge energy (When the discharge energy is 7 kJ, the expansion ratio is 24% and the thinning ratio is 22%), and the maximum deformation position is closed to the center with the increasing of discharge energy (When the discharge energy is 7 kJ, the maximum deformation position is located in the center area). Furthermore, when the discharge energy is constant and the forming temperature is adjusted to 25-150 ℃, the maximum diameter of deformed tube has no obvious change, indicating that during the high-rate forming process of magnetic pulse impacting, the forming temperature in the range of 25-150 ℃ has a weak influence on the deformation of 5A02 aluminum alloy tube. In addition, the influences of composite forming for magnetic pulse impacting elastic medium preforming at room temperature and quasi-static forming at the forming temperature of 100 and 150 ℃ on the forming of 5A02 aluminum alloy tube were explored. The results show that compared with quasi-static forming and magnetic pulse impacting elastic medium forming, the compound forming is easier for the tube to obtain a greater degree of deformation to fill the die
