Abstract

The invention discloses a portable fast-cutting device and belongs to the technical field of machining. The portable fast-cutting device comprises a shell body, a shaped charge liner, and a detonating device; the shell body is provided with a cavity and a water filling nozzle, the shaped charge liner is fixed inside the cavity and divides the cavity into a first cavity body and a second cavity body, the first cavity body and the second cavity body do not communicate with each other, the protruded end of the shaped charge liner extends to the first cavity body, the first cavity body is used for being filled with explosive substances, the second cavity body is used for being filled with cutting liquid, and the water filling nozzle penetrates through the shell body and communicates with the second cavity body; and the detonating device is arranged on the shell body and is connected with the explosive substances inside the first cavity body. The portable fast-cutting device is simple in structure, low in mass, easy to carry, and safe and reliable since the explosives and the detonating device are separated before use.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a portable quick cutting device. Background technique [0002] For large-volume and difficult-to-move target plates, direct casting is used to form the corresponding shape during early casting, and it is difficult to perform secondary processing and cutting. Usually the original casting can only be discarded and the mold opened again. However, the use of fast cutting linear water jet devices can facilitate secondary processing of large-volume, high-quality castings, which can save a lot of time and money. [0003] For the cutting of composite materials, the current international method is waterjet cutting, but for the composite materials that have been equipped on ships or aircrafts, there is currently no effective way to cut them, and the use of linear water jet cutting devices will not be affected by the environment. influence, which is easier to process.
