Embodiment Construction

[0012] Such as figure 1 As shown, the double-focus linear energy-concentrating cutter is composed of a drug-shaped cover 1, an explosive 2, a waveform adjuster 3, and a housing 4. figure 2 It is a part diagram of drug-type cover 1, image 3 It is a part diagram of the waveform adjuster 3, Figure 4 It is the housing 4 parts diagram. The drug-shaped cover 1 is composed of two traditional wedge-shaped covers. The explosive 2 is placed in the two wedge-shaped covers. There is an angle between the centerlines of the two wedge-shaped covers. The wave adjuster 3 is located between the angles. To reduce the mutual influence between charges on both sides, a detonator hole is arranged at the midpoint of the two edges of the casing 4, and the detonation mode is initiated at the midpoint of the two edges of the casing. After the charge is detonated, two jets are respectively formed along the two wedge-shaped corners of the drug-shaped cover 1 . The two jets converge again on the...

Abstract

The invention belongs to the technical field of engineering blasting and relates to a double-focusing linear jet cutter. The double-focusing linear jet cutter consists of a liner, explosive, a waveform regulator and a shell. The liner with the structure can be viewed as two traditional wedge-shaped covers which are relatively combined. The way of initiation is to initiate from the central points of two edges of a charged top. After the explosive is charged and initiated, the two wedge-shaped covers respectively form two jet flows along respective axes. The two jet flows are converged again on the symmetrical surface of the two wedge-shaped covers to form one condensed jet to cut metal and other materials. Compared with the existing devices for cutting the metal and other materials, the double-focusing linear jet cutter has the beneficial effects that the jetting speed and the continuous jetting length of the linear cutter are effectively improved, the power of the linear cutter is improved and the application prospect is wide.

Description

technical field [0001] The invention belongs to the technical field of engineering blasting, and in particular relates to a double-focus linear energy-concentrating cutter. technical background [0002] At present, there are mainly two types of cutters for cutting metal and other materials. One type uses a wedge-shaped cover, which has the advantage that its pestle body also contributes to the effect of explosive cutting; the other uses a round cover, which has the advantage of higher speed. the jet. In reality, it is often found that the power effect is not enough to meet the requirements of cutting metal and other materials. Contents of the invention [0003] The technical solution to be solved by the present invention is to solve the problem of insufficient power and effect in the process of cutting metal and other materials. [0004] The technical solution adopted in the present invention is: a double-focus line-shaped energy-concentrating cutter, including explosi...
