Description
Technical field
What the present invention relates to is a kind ofly to utilize energy that explosive charge produces as the energy, makes two kinds of soldered sheet metals form a kind of double vertical explosion welding device of solid phase combination interfaces.Belong to metal material and welding technology field.
Background technology
At present explosion welding technique and explosive composite material be widely used in oil, chemical industry, shipbuilding, electric power, Aeronautics and Astronautics, salt manufacturing, system alkali, metallurgy, atomic energy, digging, transportation, and every field such as machine-building among.Existing explosion welding method, generally all adopt run-in index explosion welding apparatus shown in Fig. 1 (b), and its device of Fig. 1 (a) is with (b) basic identical, and slightly inconvenience of operation, therefore in production practices, generally need not, just adopting once in a while in theoretical and experimental study, when the mechanism of analyzing the method, process and defective, is example with Fig. 1 (b) only therefore.After detonator 5 is detonated, cause that explosive layer produces detonation, explosive detonation produce a hundreds of thousands atmospheric shock wave to around propagate, wherein the high-pressure shocking wave of propagating downwards just make compound plate produce flexural deformation and with substrate generation high velocity impact, thereby compound plate and substrate are welded together.Cushion is in order to protect valuable non-ferrous metal compound plate surface, and ground is general to be adopted evenly, the sandy soil of certain packing, is not subjected to inhomogeneous bump in the process that could make the composite plate of having welded move downward and damages.The defective that the parallel method explosive welding exists: capacity usage ratio is low, explosive detonation produces shock wave to propagating all around, wherein the energy of the high-pressure shocking wave of propagating is downwards absorbed by compound plate and forms plastic deformation and interface in conjunction with required energy, and the other energy that explosive detonation produced greater than 1/2 is dissipated by the top.So the method has at most only been utilized the energy of explosive 1/2, all the other all are wasted greater than 1/2 energy; Shock wave is abominable to surrounding environment influence, and in the parallel method explosive welding, the shock wave energy greater than 1/2 is not only absorbed by steel plate, and rapidly to propagating all around.Though shock wave can be decayed into sound wave soon, but tens explosive welding producers of China explosive welding production practices many times prove that the sound wave that these shock wave attenuations become has a strong impact on house owed by a citizen safety and common people's daily life still reaching 140db from 3 kilometers of fire points.There are many countries to set up explosion chamber at present, but, apply limited because the design of explosion chamber and manufacturing relate to safety problem and invest hugely; Parallel method explosion weld process difficult parameters is with stable and control, and the technological parameter that explosive welding relates to mainly divides four big classes: data of explosive filled, material parameter, foundation parameter, installation parameter.Because parallel method, all difficult accurately control of its data of explosive filled, foundation parameter and installation parameter, the operator is careless slightly, all can cause the variation of above-mentioned three class parameters and makes weld failure.
The utility model content
The purpose of this utility model is intended to make full use of the energy of explosive, and cuts down the adverse effect of shock wave to surrounding environment, has successfully invented a kind of double vertical explosion welding device by theory analysis and experimental study.
Technical solution of the present utility model: double vertical explosion welding device is characterized in that A compound plate, B compound plate vertical parallel are fixed on the ground.The A substrate is in the A compound plate outside, and the B substrate is not provided with explosive in the B compound plate outside in the two substrates outside, between A compound plate and B compound plate explosive is set.Being explosive and medicine box between A compound plate, B compound plate, is the A gap between A compound plate and A substrate; Between B compound plate and B substrate, be the B gap.
Double vertical explosion welding device, it is characterized in that correspondence fixes A compound plate, A substrate, B compound plate and B substrate on ground foundation, and leave spacing between A compound plate and B compound plate, then A compound plate and B compound plate have constituted the upper base of explosive box automatically and have gone to the bottom, and distance is the powder charge layer thickness between A compound plate and B compound plate; Twine A substrate and B substrate with adhesive tape again, sealing constitutes two sides of medicine box, and ground has then constituted the 3rd side of medicine box, and and the ground relative edge be that the 4th side of medicine box is open; Lay explosive by funnel downwards by the four side of medicine box top; Igniting blasting.
The shock wave that explosive detonation produces all bends the compound plate of the left and right sides and produces collision and welding with plastic deformation and with the both sides substrate.Composite plate after the welding that different with the run-in index explosive welding in addition is or not to move downward with ground to bump, but to two lateral movements.
Advantage of the present utility model:
1, saved 2/3 explosive payload.
The open explosive welding structure that double vertical explosion welding device becomes parallel method is closed Welding Structure, and the energy that dissipates in the air is also utilized fully towards periphery.Same explosive payload parallel method welds successfully composite plate, and two onesize composite plates are then successfully welded in two legislations.See that from this some double vertical explosion welding device is the explosive payload of parallel device 1/2.Because explosive explodes,, saved 1/3 explosive again between two rigid walls in addition between two compound plates by theory calculating and this superposition of evidence because the explosive detonation ripple is propagated and had the load superposition.Therefore the actual explosive payload of double vertical explosion welding device is 1/3 of a parallel method, thereby has saved 2/3 explosive payload, greatly reduces processing cost.
2, cut down the adverse effect of most of shock wave to surrounding environment.
Two upright devices are used for explosive welding with the energy that parallel method dissipates, so the energy of parallel method dissipation shock wave is absorbed by the composite plate combination interface, have therefore eliminated the adverse effect of shock wave to surrounding environment.So adopt two upright devices with regard to having satisfactorily resolved explosive welding blast place problem, also can cut down finished cost greatly.
3, be easy to form the technological process of standard.
Charge depth can directly be controlled by the distance between two compound plates, need not resemble will carry out thickness measuring to every the parallel device when the cloth medicine; In two upright explosion welding apparatus, weld successful composite plate and contact with ground hardly, therefore can design separately ground, not only improved the quality of composite plate, and ground can be repeatedly used.Or the like these all show: two upright devices have been eliminated in the explosive welding some and have been unmanageable parameter, and institute forms the work pattern of standard so that form a whole set of technological process.
In sum, two upright devices improved operating efficiency, reduced processing cost, eliminated substantially explosion wave to the adverse effect of surrounding environment, and can form the standard welding procedure.
