Magnetic pulse seal riveting method of cast aluminum material shell

The invention provides a magnetic pulse seal riveting method of a cast aluminum material shell. The method comprises the steps of: (1) lineation, (2) guide hole drilling, (3) hinge hole drilling, (4)double-angle socket manufacturing, (5) nail feeding, (6) electromagnetic pulse riveting, and (7) inspection after riveting. The magnetic pulse seal riveting method of the cast aluminum material shellis high in reliability; the riveted shell can bear the shaft outer pressure of 0.35 MPa; the pressure is reduced by +-0.05 MPa after maintenance by 0.5 h; and sealing requirements are met. Compared with a traditional pneumatic hammer riveting mode, riveted heads molded by the method are better in consistency; and the riveting efficiency is improved by above 50%. 本发明提供种铸铝材料壳体的磁脉冲密封铆接方法，其包括如下步骤：步骤：划线；步骤二：钻导孔；步骤三：钻铰孔；步骤四：制双角度窝；步骤五：送钉；步骤六：采用电磁脉冲铆接；步骤七：铆接后的检验。本发明提供种高可靠性的针对铸铝材料(例如ZL114)壳体的磁脉冲密封铆接方法，铆接后壳体可承受0.35MPa轴外压，保压0.5小时后，压降±0.05MPa，满足密封要求。相比传统的气动锤铆方式，使用该方法成型后铆成头的致性更好，铆接效率提高50％以上。
