Description

TECHNICAL FIELD

[0001] The utility model relates to the field of powder industrial explosive detonation velocity test technology, especially to a kind of powder explosive natural accumulation detonation velocity testing device. BACKGROUND

[0002] At present, in the field of metal explosive welding, powder explosives are naturally laid flat on the surface of the metal to be welded, and different metal materials are welded together by high temperature and high pressure generated by explosive explosion. This method has strict requirements on the natural accumulation detonation velocity of explosives. Therefore, the detonation velocity of explosives under natural accumulation should be tested before explosive welding. At present, each manufacturer has its own testing method, and there is no unified testing standard. In particular, there is no unified standard for the natural accumulation detonation velocity testing method of explosives. Most of the time, powder explosives are scattered into paper tubes (circular), paper boxes or wooden boxes, and the sizes are not uniform, which will cause the detonation velocity of powder explosives to be different, which is more unfavorable for establishing a unified standard for powder explosive natural accumulation detonation velocity testing device.

[0003] The Chinese utility model with application number 202021119824.8 discloses a powder explosive detonation velocity testing box for explosive welding, which includes a testing box, a detonator mounting hole, a detonation velocity probe mounting hole, a detonation velocity probe, a supporting rod, a sliding rail, a feeding barrel, a feeding pipe, a plate chain and a plate chain rack. The utility model does not solve the above-mentioned technical defects. UTILITY MODEL CONTENT

[0004] The present application solves the problem that most users do not have a unified standard when implementing powder explosive natural accumulation detonation velocity testing device in detonation velocity testing. Most of the time, they use wooden boxes or paper boxes of random size for detonation velocity testing, which causes the explosive charge diameter to be inconsistent, making the detonation velocity test results incomparable.

[0005] Therefore, the present application provides a powder explosive natural accumulation detonation velocity testing device, which includes a bottom plate, characterized in that: the front, rear, left and right of the bottom plate are respectively provided with front, rear, left and right partitions to form a rectangular groove structure with an open top; the front and rear partitions are provided with detonation velocity probe mounting holes, and the detonation velocity probe mounting holes penetrate through the front and rear partitions; and the right partition is further provided with a detonator mounting hole.

[0006] The effect of the rectangular groove structure powder explosive natural accumulation detonation velocity testing device is that it can first accommodate powder explosives, and the upper surface is not closed to make it easier to place powder explosives in the explosive filling container. The detonation velocity probe mounting holes on the front and rear partitions facilitate the installation and use of the detonation velocity probe.

[0007] The detonator mounting hole arranged on the right partition plate is used for facilitating the contact between the detonator and the powder explosive in the explosive filling container.

[0008] Further improvement lies in that the inner wall of the rectangular groove is 276±20mm long, 40±20mm wide and 30±20mm high.

[0009] Effect lies in that the scientific numerical mode is beneficial to the performance improvement of the whole utility model.

[0010] Further improvement lies in that the front partition plate comprises a first detonation velocity probe mounting hole, the first detonation velocity probe mounting hole is arranged at a position 15±5mm below the plane of the front partition plate and 92±5mm right to the left side of the front partition plate, and the front partition plate further comprises a second detonation velocity probe mounting hole, the second detonation velocity probe mounting hole is arranged at a position 50±5mm left to the first detonation velocity probe mounting hole.

[0011] Effect lies in that the detonation velocity probe mounting holes arranged at specific positions can make the production of the utility model more standard, use more convenient, further improve the performance of the whole utility model and the use experience of users.

[0012] Further improvement lies in that the rear partition plate further comprises a third detonation velocity probe mounting hole and a fourth detonation velocity probe mounting hole, and the third detonation velocity probe mounting hole and the fourth detonation velocity probe mounting hole are symmetrically arranged with the first detonation velocity probe mounting hole and the second detonation velocity probe mounting hole on the front partition plate.

[0013] Effect lies in that the detonation velocity probe mounting holes arranged at specific positions can make the production of the utility model more standard, use more convenient, further improve the performance of the whole utility model and the use experience of users.

[0014] Further improvement lies in that the diameter of the detonation velocity probe mounting hole is Φ1±0.2mm.

[0015] Effect lies in that the scientific numerical mode is beneficial to the performance improvement of the whole utility model.

[0016] Further improvement lies in that the detonator mounting hole is arranged at a position 15±5mm from the upper plane of the right partition plate and 30±5mm from the front side of the front partition plate to the rear partition plate.

[0017] Effect lies in that the detonator mounting hole arranged at specific positions can make the production of the utility model more standard, use more convenient, further improve the performance of the whole utility model and the use experience of users.

[0018] Further improvement lies in that the diameter of the detonator mounting hole is Φ7±0.5mm.

[0019] The effect is that the scientific setting of the numerical mode is beneficial to the performance improvement of the whole utility model. Advantages

[0020] The testing device for the natural accumulation detonation velocity of powdery explosive provided by the utility model solves the problem that the natural accumulation filling container of the powdery explosive selected by most users in the detonation velocity test does not have a unified standard shape and specification, thereby causing uneven diameter density of the explosive, and affecting the scientific nature and rigor of the detonation velocity test result.
