By using above-mentioned technical proposal, aluminium strip is in a stepwise manner in continuous stamping die and progressively punch forming, greatly
Width improves production efficiency, in addition carries out the general profile that multi-drawing forms optical fiber crimping set in aluminium strip forming process first；
Then carry out taper shaping so that the junction surface of connection small end and big end is more smooth, meets size requirement, secondly quick
The epidermis of cladding is extended out along taper surface outside guiding optical cable, improves efficiency during assembling；Subsequent small end bottom leveling improves dress
The installation accuracy of timing；And then after the stretched step of big end, cladding area of the epidermis in optical fiber crimping set outer surface is expanded,
The fixing of connection can be improved after being fixed to optical cable；Last punching and blanking completes the process on continuous stamping die, after blanking
The small end slot tail carried out is processed so that forming annular groove on small end outer wall, and optical cable is penetrated to optical fiber crimping set from small end, in ring
A compression ring can be embedded on groove, is connected by pressing firmly to cover compression ring with optical fiber crimping, compression ring can be by optical cable
Epidermis is fixed, and improves the pulling capacity of optical cable, finally goes flash removed to improve surface anticorrosion by surface treatment so that it is final into
Product optical fiber crimping set no matter install convenient, connection fixing and service life on be respectively provided with preferable performance.
Composition preferably, further includes step A1 before step A, pre- punching, which is specially：
Aluminium strip is delivered at pre- punching cavity plate, and forms protrusion on the surface under the punching press effect of pre- punching punch-pin in aluminium strip
Pre-punching piece.
By using above-mentioned technical proposal, aluminium strip carries out pre- punching first before being stretched so that is formed on aluminium strip
One pre-punching piece, has drawn a circle to approve a stamped area, facilitates follow-up stretching, while can prevent aluminium strip from wrinkling in drawing process, carries
High Forming Quality.
Preferably, further included between step E and step F：
Step E1, small end inner chamfer：Stamping E is transported at small end inner chamfer cavity plate, and in the punching press of small end inner chamfer punch-pin
Terminal interior surface under effect in small end forms inner chamfer；
Step E2, big end pre-cut chamfering：Stamping E is transported at big end pre-cut chamfering die again after completing step E1, and big
Hold the terminal interior surface under the punching press effect of pre-cut chamfering punch-pin in big end to form inner chamfer, while cut in the outer surface of big end
Go out a cut channel.
By using above-mentioned technical proposal, inner chamfer is formed in the small end and big end inner surface of optical fiber crimping set, is played
Guiding role, facilitates the connection of follow-up optical cable while can avoid the fracture of optical fiber.
Preferably, step A aluminium strips are successively by the first stretching cavity plate, the second stretching cavity plate, the 3rd stretching cavity plate, the
Four stretching cavity plates, the 5th stretching cavity plate and the 6th stretching cavity plate, and drawn successively under corresponding stretching convex die punching press effect
It is stretched into type.
By using above-mentioned technical proposal, aluminium strip is stablized after six stretchings and slowly molds optical fiber crimping successively
The general profile of set, improves yield rate.
In conclusion the invention has the advantages that：
1st, utilize continuous stamping die by base material of aluminium strip, by by aluminium strip input to carry out in continuous stamping die continuously into
Type, coordinates following process to improve the production efficiency of product；
2nd, aluminium strip first passes through pre- punching and is easy to posterior drawing before the stretching, and after the stretch also by taper shaping and stretching big end
Step, expands the cladding area of optical cable epidermis and carries out grooving to small end after blanking, after raising epidermis is compacted ring compression
Fixed property, secondly the convenience also when small end and the inner surface of big end carry out chamfering easy to connection, greatly improved into
Type quality.
