Spin slot is 2~5 circles along the circumferential number of turns of shaping dies body, and optimal is 3 circles, not only has faster speed of production during 3 circle,
And during armor shaping, can be more constant for the power output that armor material is promoted.
Alloy in the method for the present invention, can use the alloy material of above-mentioned formula.
The present invention has the advantages that manufacture method is simple, easily grasp, it is not necessary to complicated armor former, saves
The input of equipment.
The present invention method in, armor bulk material have stronger hardness, armor bulk material from anti-back end with
The junction of shaping dies body is continuously conveyed along helicla flute to shaping extreme direction, due to the diameter of shaping dies body
The no more than diameter at anti-back end, and with shaping dies body junction, the diameter at anti-back end is minimum, toward connecting seat at diameter increase
Greatly, thus armor body will not slide to anti-back end, but inertially along helicla flute continuously to shaping under thrust
Extreme direction is conveyed；In helicla flute formed spring blank, due to the diameter of configured ends be not more than shaping dies body diameter, into
The configured ends diameter of shape end and armor body junction is maximum, from configured ends and shaping dies body junction toward configured ends
The diameter of other end configured ends is tapered into, therefore spring blank is advanced into configured ends and constantly drawn, and ultimately forms compared with external diameter
Stable finished product armor.
In the above method, when the speed of finished product armor traction is slightly less than the speed of armor bulk material propulsion, armouring
It is close between the adjacent turn of layer body, it is, of course, also possible to which simultaneously rapid curing viscose glue is sprayed at finished product armor makes armouring
The adjacent turn of layer body is firmly close to, and tight tube fiber is isolated moisture content, and armor is more attractive in appearance；When
So, the speed that can also draw finished product armor is slightly larger than the speed that armor bulk material is promoted, in this case, armouring
There are gap, referred to as turn-to-turn gap between the adjacent turn of layer body, the speed and armor body drawn by finished product armor
Regulation between the speed that material is promoted, makes turn-to-turn gap be less than the diameter of tight tube fiber and more than zero；In this case, spring armour
The structure for filling layer is relatively stablized and is relatively easy to construction, and tight tube fiber is easy to take out during construction.
In the present invention, after armor bulk material is blocked, end seals are carried out, you can realize armor body interior
The holding of liquid cooling medium；In general, one end is connected in the rack of tower top or cabinet to comprehensive cable in the present invention
, convenient power supply is not only realized, and can be radiated using the fan in rack or cabinet, the wind of fan can lead to
Enter in armor endoporus.
In the present invention, armor body forms spring sheathed structure, and tight tube fiber is located inside spring sheathed structure, no
Optical guide unit is there is extraordinary softness and because spring sheathed structure has preferable compressive property, therefore make
Obtaining spring sheathed structure also has excellent lateral pressure resistant performance；Further, since the armor endoporus of armor body has cooling
Medium, so that the heating of insulated conductor can be lowered, heat is pulled away, cooling medium can be cooling or freezing liquid, may be used also
With cooling gas, the gas even flowed etc.；The communication performance of optical fiber at a suitable temperature is not only ensure that, moreover, can
To reduce the temperature inside comprehensive cable, make the current-carrying capacity of conductor bigger；In the present invention, because the length of condensation cable in itself will not be too
Long, therefore, conductor can use copper, aluminium or alloy conductor, can cause during using aluminium or alloy conductor comprehensive cable weight it is lighter,
Cost is lower；Equally, it can cause that comprehensive cable weight lighter, cost is lower when the material of armor body is aluminium or alloy；When
So, there is armor endoporus cooling medium to be not limited to cooling medium, actually can also be heat medium, comprehensive cable can be made to exist
Normally used under colder environment.
Therefore, the present invention has following main advantageous effects：Weight lighter, more compact structure, electrical overload ability
Optic communication ability under stronger, high temperature is more stable.
The present invention is not limited to above-mentioned preferred forms, it will be appreciated that design of the invention can be by other a variety of shapes
Formula is implemented to use, and they are also fallen within protection scope of the present invention.
