| 目的 为了掌握磁阻型电磁铆接新技术，研究工艺参数对铆接驱动力的影响规律。方法 通过改变放电电压、线圈导线截面尺寸和弹丸尺寸等参数进行磁阻型电磁铆接试验研究，分析各参数对直径为8 mm的2A10铆钉镦头变形的影响，与感应式电磁铆接的成形铆钉进行对比。结果 随着放电电压的升高，铆钉镦头变形量增加;相同放电能量下，导线截面尺寸为2 mm×3 mm的线圈铆钉变形量小于3 mm×4 mm的线圈，弹丸直径为33 mm的铆钉变形量要大于弹丸直径为28 mm铆钉的变形量。相同放电能量下，外径70 mm螺线管线圈铆钉的变形量大于外径为120 mm平板线圈铆钉的变形量。结论 线圈和弹丸的相关参数是影响磁阻型电磁铆接吸引力的重要参数。与感应式电磁铆接相比，磁阻型电磁铆接能量利用率更高，其线圈外径更小，为电磁铆枪小型化提供了一种新方式。 |

| To master the new technology of reluctance electromagnetic riveting, the influence of process parameters on riveting driving force was studied.The effects of various parameters the deformation of 2A10 rivet upsetting head with diameter of 8 mm were analyzed by changing the discharge voltage, coil wire cross-section size and projectile size, and compared with the forming rivet of induction electromagnetic riveting. As the discharge voltage increased, the deformation of the rivet head increased. At the same discharge energy, the rivet deformation of the coil wire cross-section size 2 mm×3 mm was less than that of the coil wire cross-section size 3 mm×4 mm and the rivet deformation of projectile diameter 33 mm was greater than that of projectile diameter 28 mm. At the same discharge energy, the rivet deformation of solenoid coil with 70 mm outer diameter was larger than that of flat coil with 120 mm outer diameter. The relevant parameters of coil and projectile are important parameters affecting the attraction of magnetoresistive electromagnetic riveting. Compared with the inductive electromagnetic riveting, the energy utilization rate of reluctance electromagnetic riveting is higher, and the outer diameter of coil is smaller, which provides a new way for the miniaturization of electromagnetic riveter. |
