The composite plate for crossing explosive welding production has been widely used for the numerous areas such as petrochemical industry, aerospace, ocean engineering.With
The increasingly increase of various equipment volumes reduces production difficulty to reduce composite board splicing welding joint, improves production efficiency, because
This every profession and trade requires the area of composite plate also increasing, even more than 40m2。
Existing explosive welding is exposed in air using the exposed powder charge of flush system, explosive, is carrying out large area
Metallic explosive compound tense, explosive payload is big, and can generate problems, strong impact wave, the seismic wave generated such as explosive charge
Vegetation around, daily life are had an impact with noise.Secondly explosive charge generate energy 50% above by light, heat,
The forms such as air-shock wave are dissipated in ambient enviroment, and explosive welding capacity usage ratio is low, pollute environment.Furthermore this method is difficult
To form mechanization production, the development of explosive welding industry is seriously hindered, therefore it provides a kind of enhancing welding explosive energy
Method is imperative.
Summary of the invention
For above situation, for the defect for overcoming the prior art, it is an object of the present invention to provide a kind of enhancing explosive welding
The method of explosive energy, can effectively solve existing explosive welding and charging amount is big, capacity usage ratio is low, waste of resource, environmental pollution,
The problem of being difficult to mechanization production.
The technical solution that the present invention solves is, a method of enhancing explosive welding explosive energy, comprising the following steps: a,
Metal blank to be welded is processed into surface roughness less than 12.5 μm, with acetone or alcohol wipe by the preparation of metal blank to be welded
Dirt in surface to be welded；B, metal substrate and metal compound plate are installed, metal substrate is filled on fort, is erected above metal substrate
If the directly identical support of dress stem structure, support upper horizontal fills metal compound plate, rim frame on metal compound plate periphery, on metal compound plate
Face fills latticed paper frame；C, blasting charge loads explosive (metallic explosive weldering special dynamite, commercially available production in the gap of paper frame
Product), the explosive and paper frame of filling are contour；D, cardboard is covered, covers cardboard in the upper surface of paper frame, cardboard upper surface is uniformly placed
Grain nitride layer, the top surface of the layer of particulate matter are lower than the top surface of frame；E, detonator is placed, detonator is installed on compound plate, detonator passes through
Cardboard and layer of particulate matter extend to above layer of particulate matter；F, ignite detonator, and detonator causes explosive charge, realizes explosive welding.
The method of the present invention is simple, use easy to install, at low cost, and using effect is good, improves explosive welding capacity usage ratio, section
About explosive consumption, safety and environmental protection is the innovation on explosion welding method, and economic and social benefit is significant.
Detailed description of the invention
Fig. 1 is the structure top view that the present invention installs；
Fig. 2 is the cross-section structure main view that the present invention installs.
Specific embodiment
Below in conjunction with attached drawing and particular condition in use, specific embodiments of the present invention will be described in detail.
As shown in Figure 1, 2, a kind of method for enhancing explosive welding explosive energy of the present invention, comprising the following steps: a, to be welded
Metal blank to be welded is processed into surface roughness less than 12.5 μm by the preparation of metal blank, to be welded with acetone or alcohol wipe
Dirt in junction；B, metal substrate and metal compound plate are installed, metal substrate 2 is filled on fort 1, metal substrate 2 is perpendicular above
If the directly identical support 3 of dress stem structure, 3 upper horizontals of support fill metal compound plate 4, rim frame 9 on 4 periphery of metal compound plate, metal
Compound plate 4 fills latticed paper frame 5 above；C, it is dedicated fried to load the weldering of explosive 6(metallic explosive in the gap of paper frame 5 for blasting charge
Medicine, commercial product), the explosive 6 and paper frame 5 of filling are contour；D, cardboard is covered, on the upper surface of paper frame 5 covering cardboard 7, cardboard 7
Layer of particulate matter 8 is uniformly placed on surface, and the top surface of the layer of particulate matter 8 is lower than the top surface of frame 9；E, detonator is placed, on compound plate 4
Detonator 10 is installed, detonator 10 passes through cardboard 7 and layer of particulate matter 8 extends to above layer of particulate matter；F, ignite detonator 10, and detonator 10 draws
Burster explosion, realizes explosive welding.
In order to guarantee using effect and easy to use,
The support 3 is copper sheet.
The paper sheet thickness of the paper frame 5 is 0.5-1.5mm.
The side length of element of the paper frame 5 is not more than 100mm.
The detonator 10 is placed in the center of compound plate 4.
The cardboard 7 is with a thickness of 2mm.
The weight of the layer of particulate matter 8 is not less than the weight of compound plate 4.

The layer of particulate matter 8 is made of mountain flour.
The method of the present invention is suitble to the welding for all Explosive Welding Composite Plates being currently known, such as aluminum steel, copper steel, nickel steel, titanium
When explosive welding, detonator is ignited for steel, silver-colored steel etc., explosive charge, support melting, and compound plate moves downward, and (is guaranteeing that compound plate fills
Under conditions of point accelerating, the gap between substrate, compound plate is minimized), compound plate, substrate contact, with being welded on substrate, compound plate
Together.
The specific following advantageous effects of the present invention:
(1) due to the support of paper frame and cardboard (or plank), charge depth is not influenced when covering layer of particulate matter, so that explosive propagation of explosion
Stablize, realizes good explosive welding effect.
(2) at low cost, it is easy to operate, it is easy to implement automation.
(3) explosive loading amount reduces 1/3 to 1/2, reduces explosive cost.
