Description
Technical field
The present invention relates to a kind of bar-shaped metallic composite, the metallic composite of the complex method that especially explodes belongs to metallic composite and makes the field.
Background technology
Composite metal plate is widely used in industries such as oil, chemical industry, pharmacy, boats and ships, electric power, metallurgy at present, continuous development along with material science and equipment manufacturing technology, titanium and copper composite bar has obtained very using widely in industry such as present electrolysis and chlor-alkali manufacturing, titanium copper-clad rod mainly is to utilize the corrosion resisting property of excellence of coating metal-titanium and the excellent conductive performance of core metal-copper, under than the deep-etching working condition, as a kind of conductor of bearing great current.Because the protection of coating metal pair copper metal has stoped the corrosion of copper conductor, has guaranteed the uniformity consistency of current density, has improved the credit rating of electrolytic production, conductor is exempted from cleaning simultaneously, has eliminated the pollution of the electrolyte that the corrosion because of copper conductor causes.Therefore the excellent specific property of titanium and copper composite bar must be brought the lifting of the quality of product, the raising of production work efficiency, the reduction of energy consumption and the minimizing of labour intensity etc.
But at present to explosive as the energy, the technology by blast composite methods production compound bar yet there are no open, the especially compound blast of titanium material and copper rod, the blast of this composite is extremely significant.
Summary of the invention
Technical problem solved by the invention is, as the energy, the compound bar of producing titanium material and copper rod by the blast composite methods is to satisfy the purposes and the needs of the etching apparatus of process units in the industries such as China's electrolysis and chlor-alkali manufacturing with explosive.
Technical scheme of the present invention is: at 1-3mm, the diameter of copper rod is at 25～500mm at 30～505mm, wall thickness for the explosion welding method of titanium-copper compound bar, the internal diameter of titanium pipe; But explosion time is selected the diameter 2～5mm of the internal diameter of titanium pipe greater than copper rod; Select smooth ground as the basis, horizontal positioned technology base plate, diameter 2～5mm titanium pipe and the copper rod of diameter greater than copper rod placed respectively in the technology groove of technology base plate, build and seal up adhesive tape with technology between titanium pipe suitable for reading and the copper rod, technology groove and technology lid equate the gap all around of titanium pipe and copper rod; The feature of technology groove and technology lid is several salient points or a circle tongue to be arranged being slightly larger than on the circumference of copper rod; Again at titanium pipe overcoat one macromolecular material pipe, the macromolecular material pipe is as the medicine frame, its lower end places in the base plate technology groove, suitable for readingly support with locating rack, arrange the lower explosive of explosion velocity along upper orifice, finally make the full explosive of stype in the medicine frame, the thickness of pencil is the 30-80% of titanium pipe and copper rod entire radius, detonator inserts technology lid center in the pipe, makes it to realize the large-area continuous welding of whole rod.
Improvement of the present invention is: along the medicine frame is that the pvc pipe mouth is arranged the lower explosive of explosion velocity, accounts for the 10-30% of whole rod height.The thickness of pencil is the 30-60% of titanium pipe and copper rod entire radius.The internal diameter of titanium pipe is greater than the diameter 2.5～3.5mm of copper rod.
The macromolecular material pipe (pvc pipe, stream mould the pipe or ebonite tube all can), the thickness of pencil is the especially 30-60% of titanium pipe and copper rod entire radius; Detonator inserts technology lid center (in the aperture) in the pipe, makes it to realize the large-area continuous welding of whole rod, by can making the applying rate reach 98% after the compound one-shot forming of exploding, and minimum shear strength τ
b〉=196Mpa.
The blast of titanium-copper compound bar is compound to be the basic unit of copper rod as load, and the titanium pipe is as other one deck of bearing load.Exploding compound is to be the energy with the explosive, in the moment of igniting, explosive potential chemical energy, promptly be converted into luminous energy, acoustic energy, heat energy and mechanical energy.Exploding compound is exactly heat energy and the mechanical energy of utilizing explosive to discharge, under the effect of high-voltage pulse load, make the titanium pipe under the effect of explosive energy successively to matrix accelerated motion, and form certain bending angle, could form interatomic combination between base, compound plate, and the control of the blast binary explosive amount of rod is most critical, and external charge understands excessive deformation, so static parameter must adopt little gap, little dose.
The invention has the beneficial effects as follows: by with explosive as the energy, by more accurate control, the compound bar of producing titanium material and copper rod with the method for blast is to satisfy the purposes and the needs of the etching apparatus of process units in the industries such as China's electrolysis and chlor-alkali manufacturing.The present invention can make the applying rate reach 98% after by the compound one-shot forming of exploding, minimum shear strength τ
b〉=196Mpa.
