Embodiment
The utility model is described in detail with reference to the accompanying drawings and detailed description.
A kind of titanium al stainless steel multilayer overlarge area explosive clad plate, planar structure is as shown in figure 1, by the base of Explosion composite
Plate is constituted with compound plate, and the substrate is the stainless steel plate that thickness is 10mm~40mm, and the thickness of the compound plate is 2mm~5mm, and
Its compound plate is made up of the aluminium sheet being sequentially arranged in the stainless steel plate upper surface with titanium plate, the thickness of the aluminium sheet for 2mm~
The section of composite surface between 4mm, each laminate is in wavy metallurgical binding.
Further illustrate, the plate width of the substrate and compound plate is 30m2~36m2.The explosive clad plate, substrate is quick-fried with compound plate
Plate width scope maximum after fried shaping can reach 36m2, its substrate and compound plate unflatness≤2mm/m.
The process principle of overlarge area composite plate and general composite plate is much the same, and the compound plate prepared is placed on into substrate
On, certain slanted gap is left between two-ply.Then one layer of explosive is laid on compound plate, is produced during using explosive charge
Instantaneous super-pressure and bypervelocity impact can realize metal interlevel metallurgical weld combine.Although Explosion composite board production technology is simple
Single, production is flexible, but technical requirements are high, it is difficult to which accurate control, mother metal performance (toughness, impact property etc.), explosive property are (quick-fried
Speed is stable, safety etc.), (impingement angle, compound plate are touched for initial parameter (unit area explosive charge, base compound plate spacing etc.) and dynamic parameter
Hit speed etc.) and selection and the system of fire point coordinate and have direct influence to the yield rate and quality of composite plate.For reality
Existing titanium and stainless steel overlarge area are compound, are that this adds one layer of δ 2~δ 4mm aluminium sheet to be answered again between titanium plate and immortal steel plate
Close, i.e., first carry out aluminium sheet and stainless steel plate Explosion composite, it is then compound with titanium plate again, utilize the good plasticity transition of metal aluminum sheet
The overlarge area for completing copper and stainless steel is combined, as shown in Figure 2.
The technological process of production compound overlarge area titanium TA2 and Stainless steel 316 L is as follows:
Material purchases --- the examination of materials --- ----blanking ----surface grinding process --- --- explosive forming aluminium sheet and not
Become rusty steel plate blast --- ----aluminium/stainless steel clad plate again with titanium plate explode --- annealing --- -- leveling --- --- finishing --- ---
Surface treatment --- -- scale --- --- packaging --- ----delivery.The explosive clad plate of typical process flow and other materials
Technique is consistent.The innovative point of this patent is in the process of explosive forming, and the technique of blasting charge is different and multilayer explosive forming.
Traditional composite plate process characteristic:
1st, charging means are divided into the powder charge region of two different explosives of A, B, and A areas explosion velocity is high, and B areas explosion velocity is low.And square point
Cut.This method serves the effect that explosion velocity is gradually reduced, still, and fire point ties it to the explosion velocity in each differentiation boundary line
Conjunction rate is reduced.

2nd, slant range 10mm between base material and multiple material, stainless steel support.
3rd, Pengization nitrolite charge depth 40mm.
4th, edge is detonated.
The process characteristic of the composite plate：
1st, charging means are divided into the different explosion velocity powder charge regions of A, B, C tri-, and three region explosion velocities are reduced district by district, and Cheng Yuan
Arcuation is split, and makes that the distance in fire point to each differentiation boundary line is equal, and explosion velocity is also equal, it is ensured that the impulsive force in each region it is uniform
Property, it is ensured that Percentage bound.As shown in Figure 2.
2nd, the explosion velocity of explosive uses 2300m/s-----2500m/s.
3rd, inclined height is apart from 10mm between base material and multiple material, and aluminium bar is supported.
4th, Pengization nitrolite charge depth 45mm.
5th, central part detonates.
Obtained titanium al stainless steel multilayer explosive cladding plate, by ultrasonic inspection, its Percentage bound is 99~100%；Send power
