Detailed Description

The open end of the liner 2-1 is attached to the end of the connecting cap 1 near the outer sleeve 5, so that the open end of the liner 2-1 is located between the connecting cap 1 and the outer sleeve 5. One end of the cylinder part, which is far away from the liner 2-1, penetrates through the input electrode 6; the insulating pieces are laid along the contact surfaces of the connecting cover 1 and the outer sleeve 5, the outer sleeve 5 and the liner 2-1, the outer sleeve 5 and the input electrode 6, and the input electrode 6 and the output electrode 7 to form an insulating structure.
When the formed shot is formed, after the current output by the current generating device is input through the input electrode 6, the current flows into the liner 2-1 from the second cylinder 2-3 of the liner assembly 2, flows through the connecting cover 1 and the outer sleeve 5 from the opening part of the liner 2-1 and then flows into the output electrode 7, a circumferential magnetic field is generated in the process that the current flows through the liner 2-1, the interaction between the magnetic field and the current generates Lorentz force to be loaded on the surface of the liner 2-1 (the force which is upwards along the central axis of the liner 2-1 is applied to the outer surface of the liner 2-1), and the Lorentz force crushes the liner 2-1 towards the axis to form the formed shot to penetrate the target. The length-diameter ratio, the speed and the form of the formed shot can be effectively controlled by changing parameters such as the taper angle, the wall thickness and the structure of the liner 2-1 and adopting currents with different waveforms and peak values, so that the capability of the formed shot can be effectively controlled to be centralized, the forming process can be effectively controlled, and the detonation products in the forming process can be prevented from flying apart.
