Autonomous firing line shearing device

Abstract

The invention discloses an autonomous firing line shearing device. According to the autonomous firing line shearing device, a firing line is automatically sheared through separation movement generated by the firing line, the situation that the connecting position of the firing line at a launching tube end is damaged is avoided, ammunition and the launching tube are effectively controlled to be separated, and use is safe and reliable. The shearing device comprises a connector mounting seat, a socket, a seat body, a rotating body, a handle, a side blade body and a wire baffle plate; the connector mounting seat and the seat body are fixed on a boss on the peripheral surface of the launching tube; the socket is fixed on the connector mounting seat; the rotating body is mounted on a cylindrical rod on the surface of the seat body in a sleeving mode and can rotate around the axis of the cylindrical rod on the seat body; the rotating body is of a rotary structure with different wall thicknesses in the circumferential direction, and therefore the gap between the side face of the rotating body and the side where a cutting edge of the side blade body is located can be changed through rotation of the rotating body; and the firing line is inserted into the socket through a firing line plug at the end part of the firing line after being wound on the rotating body by two or more circles. The cutting edge of the side blade body can cut the firing line by utilizing the change of the gap between the rotating body and the side blade body when the rotating body rotates.

Description

technical field [0001] The invention relates to a firing wire shearing device in the process of pneumatically projecting a carrier or gunpowder to launch ammunition, in particular to an autonomous firing wire cutting device, which belongs to the field of machinery. Background technique [0002] In the process of general pneumatic projectile carrier or gunpowder launching ammunition, the firing line connecting the carrier (ammunition) and the launch tube is directly pulled off after the carrier (ammunition) flies away from the launch tube, and no mechanical device is used to cut the firing line; some pneumatic projectiles In the process of launching ammunition from the carrier or gunpowder, the firing wire is separated by using a drop-off plug mechanism. [0003] Above-mentioned two kinds of methods all have defects: adopting the way of directly pulling off the firing wire will easily cause damage to the connection of the firing wire at the end of the launch tube; adopting a ...

AI Technical Summary

Problems solved by technology

[0003] Both of the above two methods have defects: the method of directly pulling off the firing wire may easily cause damage to the connection of the firing wire at the end of the launch tube; the use of a drop-off plug mechanism to separate the firing wire is complicated and the manufacturing cost is high
