Abstract
The present invention is explosive welding apparatus and process for ultrathin composite metal material. The explosive welding process includes setting the upper sheet and the base sheet on one steel base in parallel and with some gap in between; setting the steel base on some sand base, painting the upper sheet with grease, adhering an box holding explosive on the upper sheet, and setting detonator onto the explosive. The present invention compounds lowest critical explosive loading thickness to realize the explosive welding for ultrathin composite metal material, and can obtain explosive welded ultrathin composite metal material without deformation and surface damage.
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 soldered metal surfaces form the explosive welding process of ultrathin coherer Composite panel of firm solid phase combination.Belong to the explosion welding technique field.
Background technology
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.
At present, the composite plate that adopts explosion welding method to produce, its compound plate thickness is generally more than 2 millimeters.At the composite board below 2 millimeters, cause the explosive welding of in the explosive welding process, understanding several situations below the generation and can't realizing the super thin metal composite board for compound plate thickness owing to compound plate is too thin.
1, explosive problem.Because compound plate is too thin, adopts existing explosive, promptly uses minimum critical charge depth, also can make composite plate big ripple occur owing to detonation pressure is too high even the compound plate fracture phenomena occur to cause weld failure.
2, composite plate problem on deformation.Because compound plate and substrate are all very thin, composite plate can produce bigger distortion and cause the postwelding smoothing with high costs after the explosive welding.
3, compound plate surface protection problem.Because compound plate is too thin and mostly be non-ferrous metal greatly, tends to make the compound plate surface breakdown in the super thin metal explosive welding process.
Owing to above several reasons, the therefore general blast+composite technique for rolling production super thin metal composite that adopts.And rollingly be divided into two kinds of cold rolling and hot rollings, in general, because its two kinds of strengths of materials are all not high, so adopt cold-rolling process as copper-aluminum composite plate; And adopt the hot rolling technology manufacturing to form as explosive clad plates such as copper-steel.Because rolling especially hot rolling cost height, and lumber recovery is low, the combination interface of explosive clad plate is had special requirement again, so the blast+rolling technique of super thin metal composite sheets such as copper-steel, stainless steel-steel does not form industrialization as yet yet.
With respect to the compound cut deal material of blast, above-mentioned composite sheet is industrial even wider in the range of application of daily life field, therefore the problem that exists at present explosive welding composite sheet, by theory and experimental study, invented explosive welding process of ultrathin coherer Composite panel, can produce the super thin metal composite by single explosion weld process, and cost is significantly less than blast+composite technique for rolling.
Summary of the invention
At three subject matters that occur in the super thin metal composite explosive welding process, the present invention successfully overcome above-mentioned three technical barriers by theoretical research and test of many times, thereby formed the explosion welding technique of the perfect super thin metal composite of a cover.
Technical solution of the present invention:
1, explosive formulation and charge depth design.Because compound plate is too thin, adopts existing 2# rock dynamite, promptly uses minimum critical charge depth, also can make composite plate big ripple occur owing to detonation pressure is too high even the compound plate fracture phenomena occur to cause weld failure.It is main material that the present invention adopts the 2# rock dynamite, and adds materials such as salt, perlite, saw powder by a certain percentage, guarantees that performances such as its explosion velocity of explosive of filling a prescription, quick-fried heat, brisance all are applicable to the explosive welding of super thin metal composite.
2, composite plate problem on deformation.Because compound plate and substrate are all very thin, composite plate can produce bigger distortion and cause postwelding to smooth after the explosive welding, because thin plate smoothing difficulty is big and with high costs.Therefore when the explosive welding thin plate, to make composite plate can not produce big and irregular deformation as far as possible.General earlier with dark about 1 meter sand as ground, and adopt certain thickness base steel assurance composite plate in blast process, can not produce buckling deformation, for length and the bigger composite plate of width, then base steel need carry out size design by sag.
3, compound plate surface protection problem.Because compound plate is too thin and mostly be non-ferrous metal greatly, the ultra-thin color metal tends to make the compound plate surface breakdown and causes weld failure in the explosive welding process.Earlier seal up one deck butter, and be attached to the compound plate surface as medicine box with certain thickness soft paper on the compound plate surface.Secondly, the gap also can make thin non-ferrous metal produce perforation, so the selection of the riding position in gap and clearance material is also very crucial.

The specific embodiment
Explosive welding process of ultrathin coherer Composite panel, it is characterized in that it is main material that explosive 2 adopts the 2# rock dynamite, and add materials such as salt, perlite, saw powder by a certain percentage, guarantee that performances such as its explosion velocity of explosive of filling a prescription, quick-fried heat, brisance all are applicable to the explosive welding of super thin metal composite.
Explosive welding basis general earlier with dark about 1 meter sand as ground, and adopt certain thickness base steel to guarantee that composite plate can not produce buckling deformation in blast process, for length and the bigger composite plate of width, then base steel need carry out size design by sag.
About the compound plate surface protection, seal up one deck butter on the compound plate surface earlier, and be attached to the compound plate surface as medicine box with certain thickness soft paper.Secondly, the gap also can make thin non-ferrous metal produce perforation, so the selection of the riding position in gap and clearance material is also very crucial.
By the igniting blasting explosive, can realize that the blast of super thin metal material is compound.
