Abstract

The invention provides a cutting-off device of an indium wire for sealing a low-temperature pressure accumulator. The cutting-off device is used for cutting the indium wire with specific length, and overcomes the problems that in the prior air, in regard to special material cutting, the length and the angle of the cut indium wire cannot meet the technical requirements of the drawing, and the section of the cut indium wire is not flat and is large in deformation. A transmission assembly can be controlled through an electrical system, so that a movable cutter rest assembly can carry out accuratepositioning according to the length of the indium wire needing to be cut off; and the section of the indium wire is flatly pressed and cut off according to the length and the angle required to be cutoff through a cutting-off mechanism with a pressing structure.

Description

technical field [0001] The invention relates to an indium wire cutting device used for sealing a cryogenic pressure accumulator, belonging to the field of special aerospace material processing. Background technique [0002] The pressure accumulator is installed at the end of the rocket fuel delivery pipe at each stage and connected to the engine inlet, and is mainly used to suppress the POGO vibration of the rocket. The pressure accumulator has the functions of frequency reduction, frequency stabilization and pressure reduction (amplitude reduction, voltage stabilization, and pulsation absorption). It can also reduce the water hammer pressure generated when the engine starts and shuts down, ensuring the flight safety of the rocket. The working environment of rocket cryogenic fuel determines that accumulator products must have good cryogenic sealing performance. Compared with the normal temperature system, the low-temperature sealing structure is very different. This is beca...
