Description
Technical field
The invention belongs to energetic material and metal composite field, relate generally to preparation and the texture interface blast pressure of " skin " explosive
The key technology closed.
Background technology
Along with the development of modern industry, the performance of single constituent element metal material has been difficult to meet requirement, compared with single metal,
Layered composite metal plate combines the respective advantage of metal constituent element, can obtain the process based prediction model that single metal does not has.Layer
The main production process of shape clad metal sheet includes explosive welding, rolling, explosive welding+roll-bonding method.Roll-bonding method is raw
Constituent element composition and the width of the composite plate produced are limited by mill milling ability, and current widely used explosive welding process produces stratiform
Composite metal plate.Composite metal plate can improve the intensity of bulk material, fracture toughness, impact flexibility, corrosion resistance, high temperature resistant
The performances such as property, wearability, with meet the industries such as chemical industry, space flight, naval vessel, electric power to the different physics of metal material, mechanics and
The requirement of chemical property, decreases the consumption of metal mine resource and the energy simultaneously.
Explosive welding is with explosive as the energy, and after explosive charge, the detonation wave of high-speed motion and the part energy of explosion product are transmitted
To coating and be absorbed, after coating and basic unit mutually clash into, it is converted into intermetallic combination energy, so that they are welded on
Together.The powdery ammonium salt of explosive welding many employings low blasting speed or ammonium nitrate-fuel oil mixture, but it is easily formed the agglomerate differed in size, charge depth
Uneven, thus affect repeatability and the stability of explosion weld process.The explosive charge of explosive welding unit are is big, energy profit
Low by rate, single bonding area only has ten a few to tens of squares, and creates serious atmospheric pollution, sound pollution, blast
Vibration and superpressure.Needed for explosive welding, condition is harsh, it is necessary to can be only achieved preferable composite effect in narrow " blast window ",
When basic unit and the physical property such as the density of coating and fusing point differ bigger, it is difficult to form obvious sinusoidal wave form, easily produce tight
The superfusion phenomenon of weight and brittle intermetallic thing, cause bond strength inadequate, and welding quality is defective.
In the document delivered disclosed, patent, data, not yet find the preparation about " skin " explosive and texture interface is quick-fried
The report of fried compression method.

The preparation of explosive.
The technical scheme of texture interface blast pressing can be summarized as follows:
The key technology of texture interface blast pressing is: cladding plate or substrate surface have certain " texture " structure, (quick-fried at explosive
Fried fiber, " skin " explosive) explosion energy effect under, cladding plate high-speed impact substrate, evagination or smooth cladding plate press-in substrate
Female, the projection of baseplate material " falls into " and enters female on cladding plate, and substrate and cladding plate are by this dislocation each other
And relative motion, realize combining closely under physical deformation and metallurgical binding act on jointly.Technique scheme is to base, cladding plate
Material and size no requirement (NR), explosive kind also not specially provided for, can choose at random according to actual needs, all can realize pressing of exploding.
" texture " described in technique scheme refers to have effigurate rough pattern, as floating-point, groove, ripple,
Impression, burr etc..
Compared with existing explosion welding technique, superiority and distinguishing feature that the present invention is possessed are:
(1) unit are explosive charge of the present invention is little, and capacity usage ratio is high.Explosive welding explosive mostly is low explosive, unit
Area explosive charge is big, and capacity usage ratio is low.The metal shell of blast fiber or the non-metal shell such as plastics, resin are to RDX
Play the effect adding strong constraint, reduce the cut off diameter of explosive, reduce unit are explosive charge, improve energy utilization efficiency；" skin
Skin " explosive then by increase explosive density, reduce unit are explosive charge, improve energy utilization efficiency.

Storage is got up, and compound tense measures required size as required, decreases the time of cloth medicine, it is simple to layered composite metal plate continuous
Metaplasia is produced.
(5) blast pressing texture Interface composites plate does not change physics and the chemical property of combination interface both sides sheet material.Fusing point and
The metallic explosive weld interface that the physical propertys such as density differ greatly often produces superfusion phenomenon and brittle intermetallic thing, works as metal
When plate area is bigger, cause welding quality defective because combination interface melting zone is excessive.Cladding plate and the substrate of blast pressing pass through smelting
Gold combines and the mode that combines of physical deformation forms close adhesion, and unit are explosive charge is little, composite plate combination interface without
Superfusion phenomenon occurs, the substrate of combination interface both sides and the physics of cladding plate and chemical property keep constant.
The detail that technical scheme is implemented:
(1) substrate and cladding plate surface process.Substrate and cladding plate surface first use sand papering, re-use emery cloth and alcohol washes
Cladding plate to be welded and substrate surface, keep to be combined smooth and clean, accomplishes light, flat, sliding.
(2) gap post is laid.Large area explosive welding typically uses parallel Method for Installation, substrate corner respectively to place an inverted " V "
Type gap post supports cladding plate, and gap post height is identical, time as bigger in cladding plate thickness or area, and can be at a certain distance at base
Edges of boards portion increases a little gaps post.
(3) detonation mode.Bottom the alignment detonator of blast fiber powder charge cross section, end is used to detonate；Cemented explosive uses center
Detonating in position, takes strengthen explosive charge and add the measure of strong constraint, shorten the time of non-steady detonation, make explosive fast near detonator
Speed reaches steady detonation, it is to avoid appearance half is quick-fried or puts out quick-fried phenomenon.
(4) propagation of explosion medium.Experiment uses water as the Transfer Medium of explosive charge energy, and aqueous medium can make welding energy pass
Pass uniform, stable, add strong constraint, reduce the loss of explosive charge energy, avoid the detonation product erosion to cladding plate simultaneously.
(5) blast pressing basis.Based on explosive welding selects the materials such as clay, sand, sandstone or sand grains, permissible
Absorbing and eliminate the dump energy after metallic explosive welds, reducing microcosmic and the macroscopic deformation of composite metal plate, experiment is selected and is dried
Sand based on.
