Description

Plane device for explosive compaction powder material

The utility model relates to a kind of shock wave commercial Application device, is a kind of explosive compaction dusty material plane device specifically.

Utilize explosive compaction dusty material plane device can become bulk to the dusty material explosive sintering, synthesize new material or the activation processing of exploding.Shock Wave for Industrial Appli-cation P353 introduces the explosive compaction dusty material plane device that a kind of Soviet Union uses, it comprises the charger of being made up of detonator, plane wave generator and explosive box, be located at the metal substrate of charger below, and be clipped in jacket between charger and the metal substrate, dusty material is housed in the jacket.Make the jacket high-speed motion behind the explosive initiation and the strike powder that tilts under the effect of detonation gas, make jacket and powder, form the HTHP layer between powder and the powder, powder is sintered, activates or synthesize new material under the strong shock wave effect.The low explosive of this device available rates is assembled the explosive compaction that simple charger carries out large-area dusty material, but the jacket of this device is the metal die of a sealing, when reclaiming the test specimen finished product, need to remove mould, cause jacket not reuse with machining process; The explosive box places above the cover plate of jacket, being detonated back shroud collapses under pressure and makes the accelerated motion compacted powder, but the initial launch speed of cover plate is little, the impulsive force that acts on the upper strata powder is also little, speed with back shroud increases gradually, the impulsive force that acts on lower floor increases gradually, successively strengthen later on, cause gained test specimen upper strata density little, past more lower density is big more, and is even along its thickness direction density unevenness, even the powder that is not compacted in addition at the test specimen top, need strengthen explosive payload, but this still has sufficiently high detonation pressure that jacket is done the idle work motion downwards together with test specimen when causing the explosive compaction process to finish again, causes waste for this reason.

The purpose of this utility model provide a kind of simple in structure, cheap, jacket can reuse, the uniform explosive compaction dusty material of test specimen compacting plane device.

The utility model is achieved in that a kind of explosive compaction dusty material plane device comprises charger and jacket, said charger is made up of with the detonator that is located at its center upper portion the hood-shaped explosive box of case that is located on the horizontal support face, said jacket is located in the hood-shaped explosive box of case, be positioned at the central authorities of horizontal support face, jacket is the container that is surrounded by nonmetal cover plate, metal side plate and metal base plate, the inwall of side plate and base plate is provided with nonmetal separation layer, and the lower surface of the top of cover plate, the hood-shaped explosive box of case is provided with metal and flies plate.

Detonator is located at explosive box center upper portion in the utility model, the shock wave that produces behind the ignition charge is outwards propagated in the sphere mode, under the effect of detonation gas, flying the plate middle part is bent downwardly, and flattening acts on the cover plate and powder of jacket gradually, the be hit area of ripple effect of powder still outwards enlarges gradually in the sphere mode, when expanding the jacket sidewall to, side plate is promptly pushed over, explosive compaction end back is taken out the test specimen that is compacted and is not needed to remove the jacket plate through machining, all be provided with nonmetal separation layer because of jacket side plate and plate inner wall again, can the adhesive powder powder material, so can reclaim use.Be located at the top of jacket cover plate because of flying plate again, between it and cover plate certain distance is arranged, fly plate behind the explosive initiation certain accelerator was arranged before acting on cover plate and powder, when it is accelerated to a certain appropriate speed, just act on compacted powder on the cover plate when having enough big impulsive force, therefore the gained test specimen is good along the thickness direction compacting, and density is even.

Now in conjunction with the accompanying drawings and embodiments the utility model is done specific descriptions:

Fig. 1 is the structural representation of explosive compaction dusty material plane device provided by the utility model.

As shown in Figure 1, a kind of plane device for explosive compaction powder material, comprise by being located at the hood-shaped explosive box 2 of case on the horizontal support face 9 and being inserted in the charger that the detonator 1 of explosive box 2 center upper portion forms, be located in the hood-shaped explosive box 2 of case, be positioned at the box-shaped jacket that horizontal support face 9 central authorities are surrounded by nonmetal cover plate 4, metal side plate 5 and metal base plate 6, the inwall of side plate 5 and base plate 6 is provided with nonmetal separation layer 8, and the lower surface of the top of cover plate 4, the hood-shaped explosive box 2 of case is provided with metal and flies plate 3.
