Move horizontally, it will be able to the both ends for enabling aluminum alloy to harness 11 are inserted into respectively in the side opening of attachment device 10 at both ends, simple side
Just.
In practical applications, the aluminium alloy harness placed in the second arc groove 6 can be made for the setting of punck-down block 9
11 both ends are located just at the wire stripping position of punck-down block 9, and punck-down block 9 can fix on the ground at this time.It is of course also possible to
Be equipped with mobile device in the bottom of each punck-down block 9 keeps wire stripping position more accurate to drive the movement of punck-down block 9.Tool
Body design is decided according to the actual requirements.
The inside of above-mentioned each attachment device 10 is equipped with the top electrode 101 being oppositely arranged and lower electrode 102, top electrode
Electromagnetic pulse generation area is formed between 101 and lower electrode 102.Electromagnetic pulse hair is equipped in the outside of each attachment device 10
Generating apparatus, and connect simultaneously with top electrode 101 and lower electrode 102.
Further, the both ends of top electrode 101 and lower electrode 102 are provided with cone structure, with facilitate copper tip 12 with
And the insertion of aluminium alloy harness 11.
Further, it is additionally provided with elevation and subsidence regulating device (not shown in FIG.) in the inside of attachment device 10, for adjusting
The height of electromagnetic pulse generation area, and then it is suitable for the insertion of various sizes of copper tip 12 and aluminium alloy harness 11.
In practical applications, above-mentioned connection streamline further includes the collection device for being located at the lower section of third arc groove 8,
The aluminium alloy harness 11 of copper tip 12 is connected for collecting both ends.
The whole work process of above-mentioned connection streamline is specific as follows:
By flattening the rotation of nip rolls 22, pass through with the aluminium alloy harness 11 on the aluminium alloy harness 11 on moving-wire roller 21 whole
Flat nip rolls 22 skids off, and then aluminium alloy harness 11 is skidded off by measuring box 23 again, measuring box 23 can to aluminium alloy harness 11 into
Row coding and measured length, and by one end of aluminium alloy harness 11 pass through cutting device 3 when start in terms of length.
Aluminium alloy harness 11 pass through cutting device 3 after, into the first arc groove 4 in and constantly extend, displacement sensor
When the length detected reaches preset value, aluminium alloy harness 11 will be truncated in cutting device 3, so that the first arc groove 4
Interior aluminium alloy harness 11 is the harness of designated length.
Aluminium alloy harness 11 is passed through first by the overturning that the first arc groove 4 is then driven by the first turnover mechanism
Hang plate 5 and be transported in the second arc groove 6.Due to the second arc groove 6 length less than the first arc groove 4 length
Degree, the both ends of aluminium alloy harness 11 have the both ends that the second arc groove 6 is exposed in part at this time, pass through punck-down block 9 at this time
Work can be achieved with peeling the plastic insulating layer at the both ends of aluminium alloy harness 11 off, so that the metal at 11 both ends of aluminium alloy harness is led
Body exposes.
Next, by the second turnover mechanism drive the overturning of the second arc groove 6 with by aluminium alloy harness 11 by the
Two hang plates 7 are transported in third arc groove 8, due to third arc groove 8 length less than the second arc groove 6 length
Degree, the both ends of aluminium alloy harness 11 have metallic conductor at this time and partly plastic insulating layer exposes the both ends of third arc groove 8.
Mobile device is recycled to make a relative move two attachment devices 10, so that the both ends of aluminium alloy harness 11 are distinguished
It is inserted into the side opening of two attachment devices 10.Simultaneously at this time by the work of two manipulators so that two copper tips 12 are inserted respectively
In another side opening for entering two attachment devices 10, at this moment the both ends of aluminium zygonema beam and two copper tips 12 are located in electromagnetic pulse
Generation area.
Start electromagnetic pulse occurrence of equipment, aluminium alloy harness 11 and copper tip 12 will be in the poles that strong pulse magnetic field generates
Under the action of high instantaneous pressure wave, the original metallic atom structure of two kinds of materials is destroyed, and two kinds of metallic atoms is made to interpenetrate
Into the atomic structure of other side, stable metallurgical structure is formed on surface.
Stable metallurgical structure is formed in the contact site of aluminium alloy harness 11 and copper tip 12 in this way, makes 12 He of copper tip
11 circular contact face atomic structure of aluminium alloy harness interpenetrates, and forms a kind of new metallurgical structure and combines together.
The connection of aluminium alloy harness 11 and copper tip 12 is carried out using electromagnetic pulse, on the one hand enough eliminates circular contact face
Micropore and completely cut off air or other electrolyte enter faying face, so as to effectively prevent the electrochemistry between copper, aluminium
Etching problem；On the other hand the structure for changing two kinds of copper, aluminium metals, makes its similar thermal expansion coefficient, so as to have
Effect solves two kinds of copper, aluminium metals causes the two connecting portion under thermal shock conditions repeatedly because thermal expansion coefficient difference is larger
The problem of relaxation falls off.In addition, the oxidation film on 12 surface of aluminium alloy harness 11 and copper tip is generated in welding moment high velocity impact
Metal jet effect under be completely removed, simultaneously in the metallic atom structural rearrangement of two kinds of welding position, form one kind
New metallurgical structure and combine together, completely eliminate the hole between cable and terminal, secondary oxidation can be effectively prevented
Occur, to thoroughly solve the problem of oxidation of aluminium alloy harness 11 and 12 connecting portion of copper tip.
After completing connection, two attachment devices 10 are removed under the driving of mobile device in the opposite direction again, so that complete
It is rested in third arc groove 8 at the aluminium alloy harness 11 and copper tip 12 of connection.Then it is driven using third turnover mechanism
The overturning of third arc groove 8, and then the collection that the aluminium alloy harness 11 for completing connection and copper tip 12 are transported to lower section is filled
It sets, completes entire production process.
In practical applications, above-mentioned operation can be controlled all using controller and be realized, with full-automatic operation, be improved
Production efficiency.
More than, it is only presently preferred embodiments of the present invention, is not the limitation for doing other forms to invention, it is any to be familiar with
Professional and technical personnel is changed or is modified as the equivalence enforcement of equivalent variations possibly also with the technology contents of the disclosure above
Example.But without departing from the technical solutions of the present invention, according to the technical essence of the invention to the above embodiments
