Technical Field

The invention belongs to the technical field of blasting, and particularly relates to a modular charging structure of an explosive bolt.

Background

The explosion bolt can be used as an initiating explosive device, can quickly separate connected structural parts after being excited, and is widely applied to aerospace craft products and ground test equipment. The cavity of the explosive bolt body is generally filled with explosive, and the input end of the explosive bolt body is connected with an initiator. After the detonator works, the explosive in the explosive bolt is detonated, the shock wave and the gas pressure generated by explosive charging push the bolt rod to move, the connecting pin is cut off, and the bolt rod is separated from the bolt body, so that the two connected objects are unlocked.

In the traditional explosive bolt charging process, explosives or gunpowder needs to be charged into the bolt, then the explosive is charged and then assembled, the process operation is complex, the safety is poor, the volume and the weight of the assembled explosive bolt are relatively large, and the explosive bolt needs to be integrally stored and transported according to explosive substances, so that inconvenience is caused. To this end we propose a modular charge configuration for explosive bolts.
