Description
Technical field
The invention belongs to explosion welding technique field, and in particular to a kind of explosive welding dress from constraint high-energy utilization rate
Put.
Background technology
Explosion composite is the strong impact ripple produced using explosive charge, makes plied timber and parent metal high speed angular impact
Jet is produced, junction to be welded is cleared up, so that base cladding realizes a kind of technology of metallurgical binding.Explosive composite material combines two
The advantage of kind or various metals material, so its excellent performance.And for other composites, explosion cladding process
Simply, it is not necessary to expensive experimental facilities and fine artificial operation, so explosive composite material is with low cost.By decades
The development for coming, can almost realize all intermetallic Explosion composites at present, and its product is widely used in industrial production, and
The fields such as Aero-Space, oil, chemical industry, military affairs play the role of irreplaceable.Even so, Explosion composite technology is still present
Many weak points, in traditional Explosion composite technology, directly explosive is laid on plied timber, the upper end of explosive is exposed
In atmosphere, i.e., the energy of the explosive one end for only utilizing, so explosive energy utilization rate is very low, and the incoming air of a large amount of shock waves
It is middle to cause very big noise pollution.A kind of double vertical blast is disclosed for this problem Chinese patent CN200610096800.3
Welder；Chinese patent CN201310282589.4 discloses a kind of two-sided blast weldering of horizontal based on honeycomb explosive
Connection technology, although above-mentioned two inventions can greatly improve the capacity usage ratio of explosive in theory, but in actual production
It is faced with the problem that composite plate is dispersed.During Explosion composite, plied timber is generally with hundreds of meters to thousands of meters of speed
Clash into parent metal, the speed of the composite plate of formation generally also up to hundreds of meters.For two-sided explosive welding, composite plate is without about
The long-distance flight of even hundreds of meters of tens of rice will be produced under conditions of beam or weak constraint, composite plate will gently then be damaged, it is heavy then injure
Periphery personnel, such case is not allow appearance in actual production, and the motion for how constraining composite plate then turns into
Realize the industrial key issue of two-sided Explosion composite.
The content of the invention
Explosive energy utilization rate is low during the purpose of the present invention is directed to traditional Explosion composite, and exists in two-sided Explosion composite
The problems such as the potential safety hazard that composite plate is dispersed, devises a kind of from the explosion welding apparatus for constraining high-energy utilization rate.
The purpose of the present invention is realized by following technical scheme：
A kind of explosion welding apparatus from constraint high-energy utilization rate, the explosion welding apparatus are main by one or more groups of double
Face explosive welding combination and one group of single-sided welding combination are constituted, and one or more groups of two-sided explosive weldings are combined from bottom to up successively
Stack, then overlay in the two-sided welding combination of the superiors single-sided welding combination.
Wherein, described two-sided explosive welding combination includes substrate A, support column A, compound plate A, the first knot successively from top to bottom
Structure explosive, compound plate B, support column B, substrate B, wherein, described substrate A is lain in a horizontal plane on platform, and surface is uniform thereon
Arrangement support column A.
Wherein, the support column in the combination of two-sided explosive welding should have stronger bearing capacity, preferably by aluminium or its
The cylindrical shell that his metal is rolled, it is highly the height of burst, and thickness is determined by bearing strength.
Wherein, described compound plate A levels are placed on support column A.
Wherein, described structure explosive is that its is preferred with the two-sided explosive welding application specific architecture explosive of certain bearing capacity
Be honeycomb constructed of aluminium explosive, i.e., structure explosive is constituted in honeycomb constructed of aluminium by the way that traditional explosive welding explosive is arranged in, from
And structure explosive is possessed very strong bearing capacity, two ends up and down of structure explosive are brought into close contact with compound plate A and compound plate B respectively.
Wherein, described support column B is uniformly arranged on compound plate B；Described substrate B levels are placed on support column B
On, described substrate B, compound plate B and substrate A, compound plate A are in full symmetric structure on explosive.
Wherein, described single-sided welding combination is consistent with traditional explosion welding apparatus, includes substrate C successively from top to bottom,
Support column C, compound plate C, the second structure explosive, described substrate C, compound plate C is consistent with the substrate in two-sided welding, compound plate；It is described
The second structure explosive also with two-sided welding combination in first structure explosive it is consistent.
Wherein, detonating capsule is arranged in each layer of same position of explosive, and is detonated simultaneously.
Operation principle of the invention is：It is double under the driving of explosive for the in the case of of combining containing one group of two-sided explosive welding
Composite plate in the combination of face explosive welding on the downside of explosive is moved downward, and its kinetic energy is absorbed by ground, the composite plate on the upside of explosive to
Upper motion, while the composite plate formed in single-sided welding combination is then moved downward, due to the symmetry of structure, in two pieces of composite plates
Shock strength in theory should be equal, so can be cancelled each other when the shock wave in two pieces of composite plates passes to interface, makes
Shock strength is reduced to zero, so as to constrain the motion of composite plate.When multigroup two-sided explosive welding combination, in being in
Between two-sided explosive welding composite explosive downside composite plate in shock wave combined with lower floor on the upside of shock wave in composite plate support
Disappear, the shock wave in the downside composite plate that the shock wave in composite plate on the upside of explosive is combined with upper strata is cancelled out each other.So, it is whole
Individual system is in the state from constraint.
Present invention advantage compared with prior art is：
1st, compared to traditional explosive welding, the explosion welding apparatus designed by the present invention can significantly improve the energy of explosive
Utilization rate, reduces the usage amount of explosive.Combined present invention employs one or more groups of two-sided blasts, make use of the energy at the end of explosive two
Amount, capacity usage ratio improves two times, and only with one group of single-sided welding combination.So, for there is the two-sided explosive welding of n groups
The device of combination will save explosive n/ (2n+1).
2nd, compared to two-sided explosive welding, although the device designed by the present invention sacrifices explosive one in top layer welding combination
The energy of side, but composite plate is dispersed at the middle and upper levels to solve the problems, such as two-sided explosive welding, improves solder yield and welding is made
The security of industry.
3rd, the explosion welding apparatus designed by the present invention can once weld at least 3 pieces composite plates on plot base, therefore
Operating efficiency can be significantly improved, blast place is saved.
4th, the explosion welding apparatus whole system designed by the present invention is in from restrained condition, and explosive energy utilization rate is closed
Reason, reduces the energy in the incoming air of shock wave, reduces noise pollution.
