Cylindrical underground explosion shock wave compaction device

Abstract

The invention relates to a cylindrical underground explosion shock wave compaction device, which comprises a water containing pipe, wherein the upper end of the water containing pipe is provided with a groove, the lower end of the water containing pipe is provided with a lug boss, the middle of the water containing pipe is provided with a first through hole for filling water, an explosive containing pipe is clamped and connected in the groove, the middle of the explosive containing pipe is provided with a second through hole, explosive is placed in the second through hole, a cover plate is clamped and connected on the top of the explosive containing pipe, a small hole is formed in the middle of the cover plate, an electric detonator is arranged in the small hole, a water containing PVC (polyvinyl chloride) pipe is clamped and connected at the lug boss part of the water containing pipe, the middle of the water containing PVC pipe is provided with a third through hole for filling water, the bottom of the water containing PVC pipe is clamped and connected with a powder containing pipe, the middle of the powder containing pipe is provided with a sink hole, powder to be compacted is filled in the sink hole, and the second through hole, the first through hole, the third through hole and the sink hole have the same hole diameters and are positioned on the same center line. Therefore the density uniformity of obtained blanks is good, the explosive explosion speed and the explosive containing density do not need to be regulated, and the compaction effect is good.

Description

technical field [0001] The invention relates to the technical field of explosion compaction manufacturing, in particular to a cylindrical underwater explosion shock wave compaction device. Background technique [0002] The development of national defense and economic construction requires the provision of high-density, high-performance materials, while the potential of traditional technology for the development of new materials is already at its limit. In order to obtain high-performance new materials, new technology methods have to be sought, explosive powder Compaction emerged as a new material manufacturing technique. [0003] Explosive powder compaction is a new material processing or synthesis technology that uses the energy generated by explosive detonation to act on metal or non-metal powder in the form of shock waves to make it compact under transient, high temperature, and high pressure. The above is the application of the principle of high temperature compaction o...

AI Technical Summary

Problems solved by technology

[0006] (3) Compaction occurs without adding additives, so it is possible to greatly increase the working temperature of the compacted body

[0010] However, both the above-mentioned single-tube and double-tube explosive compaction devices need to adjust the detonation velocity and charge density of the explosive, and it is not easy to adjust the parameters of the explosive, resulting in an increase in cost

In addition, the shape of the billet obtained by the steel pipe explosive compaction device has irregular shapes at both ends, so the density of the billet is not uniform
