Abstract
The invention discloses a steel aluminum compound protection plate as well as a manufacturing method thereof. Steel plates and aluminum plates are compounded in a crossed and overlapped manner; an upper panel and a lower panel are both steel plates; uncompounded surfaces of the upper panel and the lower panel, which are parallel to the compound surfaces, are provided with hardening layers; the steel plates and the aluminum plates are compounded by adopting an explosion or/and rolling method. According to the steel aluminum compound protection plate as well as the manufacturing method thereof, different hardnesses of media are utilized, the metal jet directions are changed, and partial energy is absorbed, and the protection effect can reach the level being 1+1>2; not only is the application amount of steel materials lowered, but also the protection effect is intensified. Steel and aluminum are compounded by adopting the method of explosion, or rolling or the combination of explosion and rolling, and the compound intensity is improved. The surfaces of the steel plates of the upper panel and the lower panel are subjected to hardening treatment, so that the striking resistance capability is intensified; the surfaces of the steel plates and the aluminum plates are provided with matched convex-concave blocks, so taht the compound intensity is improved further.
Description
Technical field
The present invention relates to metallic composite and make the field, be specifically related to a kind of Steel-aluminium composite board and manufacture method thereof.
Background technology
Use homogeneous steel plate or aluminium alloy separately, reaching on the certain thickness basis, can both satisfy the requirement of shelter under the different condition.But along with the increase of thickness, cause certain difficulty in process of production, if demand is huge, general manufacturer can't satisfy the equipment of production requirement again.
The composite protective plate has multilayer, and intrusive body whenever penetrates one deck all will consume certain energy.Because layers of material hardness is different with toughness, can make intrusive body change direction.Therefore, the anti-penetration of composite plate energy force rate homogeneous plate is much higher.For some high-risk places, think to transform to strengthen protective capacities fast; Some need not to spend substantial contribution at ordinary times and build armor, and need under special circumstances the target of protection emphatically, equip the protection position of use in a large number at needs, and are detachable cheap but have certain effect composite protective plate to become first-selection.
Summary of the invention
The object of the present invention is to provide a kind of steel aluminium composite protective plate and manufacture method thereof, average out a little at cost and production capacity.
The present invention is by the following technical solutions:
A kind of steel aluminium composite protective plate, steel plate and the stack of aluminium sheet intersection are compound, and top panel and lower panel are steel plate, and top panel is that the top layer is provided with hardened layer up and down with the lower panel not compound surface parallel with composite surface, wherein, adopt blast or/and milling method is compound between steel plate and the aluminium sheet.
Further, the steel plate composite surface is provided with groove or projection, and the aluminium sheet composite surface is provided with projection or the groove with steel plate composite surface coupling.
Further, the steel plate composite surface is provided with groove or projection and aluminium sheet composite surface, and to be provided with the projection of steel plate composite surface coupling or groove all are method preparations by the mold pressing compacting, and groove width is 2-10cm.
The manufacture method of above-mentioned steel aluminium composite protective plate comprises the steps:
Step 1, will treat that the polishing of compound steel plate and aluminium sheet interface is level and smooth;
Step 2, by blast or/and rolling mill practice carries out compoundly, make steel-aluminium-steel composite bed;
After step 3, compound the finishing, carry out low temperature stress-removal annealing, before or after annealing, carry out ultrasonic examination, guarantee faying face in conjunction with Shuai ≧ 95%;
The technology of step 4, repeating step 1-3 0-5 time, the stack of manufacturing steel aluminium intersection is compound, and top panel and lower panel are the composite protective plate of steel plate.
Cure process is carried out on step 5, top panel and the lower panel not compound surface parallel with composite surface, forms hardened layer, strengthens case hardness.
Beneficial effect of the present invention:
1, steel aluminium of the present invention is composited according to certain level ratio, rely at all levels between the difference of physical property disturb to attack penetrating of bullet (jet), consume its energy, and finally reach and stop bullet (jet) to penetrate.Invar hardness is higher, and tension and extension property are also high, and aluminium hardness is on the low side, but density is very light, and manufactured goods quality under the condition of equivalent thickness situation can descend, and is equal to even higher effect but also can produce.Utilize different hardness between medium, make metal jet change direction, the absorption portion energy can reach 1+1〉2 protection effect, both reduced the use amount of steel, strengthened protection effect again.
2, to adopt blast or the method for rolling or both combinations to carry out steel aluminium compound in the present invention, improves combined strength bination.Steel plate and surface of aluminum plate arrange the shaggy block of coupling, and combined strength bination is further improved.
3, the surface of steel plate of top panel and lower panel carries out cure process, strengthens anti-strike capability.

The specific embodiment
Below in conjunction with accompanying drawing the present invention is done further explanation.
A kind of steel aluminium composite protective plate, steel plate and the stack of aluminium sheet intersection are compound, and top panel and lower panel are steel plate, and top panel has hardened layer with the lower panel not compound surface parallel with composite surface, wherein, adopt blast or/and milling method is compound between steel plate and the aluminium sheet.Utilize different hardness between medium, make metal jet change direction, the absorption portion energy can reach 1+1〉2 protection effect, both reduced the use amount of steel, strengthened protection effect again.The upper surface hardened layer impels the body explosion to fragmentate and consumes certain kinetic energy.The lower surface hardened layer can further significantly slacken the kinetic energy of body.
Preferably, the steel plate composite surface is provided with groove or projection, and the aluminium sheet composite surface is provided with projection or the groove with steel plate composite surface coupling, and combined strength bination is further improved.The steel plate composite surface is provided with groove or projection and aluminium sheet composite surface, and to be provided with the projection of steel plate composite surface coupling or groove all are method preparations by the mold pressing compacting, and groove width is 2-10cm.It is wideer that the groove width of slab is wanted.
The selection of steel, aluminium material and thickness does not limit, and can select the raw material of unlike material and thickness to produce according to experimental verification material and ideal thickness ratio;
The manufacture method of above-mentioned steel aluminium composite protective plate comprises the steps:
