Description

Pre-pressing conveying module and energy-gathering cutting cable processing device thereof

Technical Field

The invention relates to a fire technology, in particular to an energy-gathered cutting rope, and specifically relates to an energy-gathered cutting rope processing device.

Background

The energy-gathered cutting rope utilizes the energy gathering effect (generally called as a 'door-lock effect'), namely after the explosive is exploded, the metal material is cut by the explosion products under high temperature and high pressure, and the explosion fragments are basically scattered outwards along the normal direction of the surface of the explosive. After copper tube explosive charge with grooves (energy-gathering angles) is detonated, a converged explosive product flow with high speed and pressure intensity can appear on the axis of the grooves, and chemical energy released by explosive explosion is concentrated within a certain range.

It is mentioned in prior document 1 that the cross-sectional shape of the cutting cord plays a critical role in the performance of the cutting cord. Referring to fig. 1, the cross-sectional shape of the cutting cord is the most ideal state of 6, and the energy-collecting angle alpha can release the energy of explosion more linearly and intensively. However, it is not possible to process the workpiece to state 6, but only to state 5 (see prior art document 2). The reason is that as long as the pipe is machined and the explosive is required to be completely compressed in the pipe before the cutting cable is machined, the outer diameter of the pipe is generally 5-10 mm, and the wall thickness of the pipe is generally about 0.2-0.5 mm; then the pipe is gradually processed to be in a No. 6 state or a state close to the No. 6 state, the cold drawing technology is mainly adopted at present, the cutting rope is required to be kept to be processed at the temperature below 70 ℃, the heat generation amount in the cold drawing process is large, the pipe is easy to deviate (the cross section is inclined), the pipe is clamped, when the pipe is clamped, a die is required to be disassembled to take out waste products, new processing can be continued, the yield is extremely low, the efficiency is very low, and at present, only about 6 pipes can be processed by one device in one day.
