Embodiment:
Referring to Fig. 1,2.The transition of copper-aluminium explosion composite electrical copper connects newspaper bar wire clamp, comprises two involutory binding clip main bodys 1, and described binding clip main body 1 is an aluminium material, and binding clip main body 1 surface explosion is welded with layer of copper 3; Described two binding clip body surfaces have or several arc line ball grooves 4 of mutual correspondence respectively, and described arcuate furrow 4 is arranged in parallel side by side; The arcuate furrow 4 sidepiece prepared screw-bolt holes of described binding clip main body 1 use bolt 2 that binding clip main body 1 is fixedly connected.
The thickness of copper 3 is between 0.1mm-8mm; Aluminium material thickness is 1mm-30mm.
The impact of performance that connects " newspaper bar wire clamp " as reaching electric power copper conductor described in the utility model, the technology problem that faces completely manifests, and promptly effectively solves obtaining and copper aluminum mother plate electric power copper conductor transition newspaper bar wire clamp later stage moulding problem of described blast complex copper aluminum mother plate.
At first, be the explosion weld process and the mother metal manufacture method of the compound mother metal of newspaper bar wire clamp copper aluminium;
In order to obtain the copper-aluminium transition composite performance of excellent copper cash folder self, the utility model has adopted the technology of explosive welding, and the copper-aluminium transition welding that solves copper cash folder self is compound;
Explosion weld process:
The essential condition that realizes the metallic explosive welding has following several respects: " assemblage gap of explosive kind, unit are dose, substrate and cladding plate and the dimensional parameters of stagger angle, substrate and cladding plate (thickness, the base that mainly contain sheet material cover ratio) and surface state " etc.
1, explosive kind
Explosive is the energy of explosive welding (EW), its kind and density decision detonation velocity.Explosion velocity is too high, and it is excessive with active force that projected angle of impact is diminished, and tears binding site easily; Explosion velocity is low excessively, can not keep enough blast angles, can not produce good combination.
Owing to be extensive use of 2 in the explosive welding engineering
#Rock explosive, in order to combine with actual production, explosive also adopts powdery ammonium salt explosive (2 in this project
#Rock explosive), its density p=0.53～0.6g/cm
3, explosion velocity 2200m/s～2600m/s.
2, unit are dose
The quantity of explosive is calculated with explosive quantity or the explosive thickness that lays on the cladding plate unit are, with Wg (g/cm
2) expression.
The calculating of dose is gear shaper without theoretical formula still at present, can adopt following empirical equation to calculate.
In the formula:
■---uniform gap value (mm)
■ W
g---unit are dose (g/cm
2)
■ ρ
1---cladding plate density (g/cm
3)
■ δ
1---cladding plate thickness (mm)
■ δ
0---cartridge bag thickness (mm)
■ K
g---metallic explosive welding empirical coefficient
3, assemblage gap and stagger angle
The energy delivery of explosive welding (EW), absorption, conversion and distribution are to collide by the high speed impact of cladding plate and substrate by the gap to finish and realize.Assemblage gap and stagger angle are one of the principal elements at influence blast angle, and be much no matter stroke speed has if the blast angle is too small in explosive welding (EW), also can not produce the jet phenomenon, causes the serious fusing of faying face on the contrary easily, and strength of joint is low.Adopt the uniform gap value during parallel method explosive welding (EW), represent, be generally 0.5～1.0 times of cladding plate thickness, generally calculate with following experience company with ho:
h
0＝0.2(δ
1+δ
0)
4, surface state
Realize intermetallic metallurgical binding, must effectively remove metal sheet surface is the cover layer of oxide, nitride and adsorbed gas film, reaches tight contact between the metallic plate for making, so that produces interatomic adhesion, establishes and realizes the basis.
Surface state has very important influence with to form the physics contact area relevant to welding quality, must carry out removing surface before the weldering and clean as much as possible with the maintenance metal surface and have certain surface roughness.Experimental result shows that coarse surface both had been difficult to form rippled interface, is easy to again melt and forms the intermediate layer of intermetallic compound.
Secondly, be the moulding process and the method for explosive welding complex copper newspaper bar wire clamp;
If the metallic composite motherboard that the metallic explosive welding manner is made becomes the suitable final required different shape and the material accessory of form of using, so! Carry out post-production necessary, that be fit to and the selection of manufacturing process just seems very important for metallic explosive soldering composite material motherboard.
Only " moulding of copper newspaper bar wire clamp " required later stage moulding process methods of the utility model indication are done an introduction at this;
In order to reach the post-production purpose of " surface quality is good, outer shape is unified, little, waste of material is few " to compound interface damage; " moulding of copper newspaper bar wire clamp " processing technology, the utility model of later stage processing and forming operation to the utility model indication selected the technology of " metal superplastic formation ", and well-known " metal superplastic formation " must satisfy three primary conditions:
1. fine-grain tissue
2. certain deformation temperature
3. low rate of straining
According to " metal superplastic formation " technological standards, the temperature rise of bonded composite motherboard needs situation, and motherboard is implemented " superplastic formation " preceding operation of heating, and heating, heat can be high-frequency induction heating, other effective means such as Frequency Induction Heating;
Moulding for the utility model " copper newspaper bar wire clamp ", motherboard is implemented " superplastic formation " preceding temperature the utility model of heating to be set in 220 ° of-260 ° of scopes and to carry out, after satisfying above condition, the explosive composite material motherboard after the temperature rise is placed, treat in the pressing mold tool, according to " rate of straining " of explosive composite material motherboard, adopt press device to give and press for mould;
So far, by for " the copper newspaper bar wire clamp " blank shape after the compression moulding, carry out the necessary later stage simply to intercept, hole, assemble and to have finished whole " moulding of copper newspaper bar wire clamp " and make.
