Abstract
The invention relates to a method for producing a number ring and fastening and sleeving the number ring on an optical cable. The method comprises the steps of: 1, placing polytetrafluoroethylene plastic particles in a heating furnace to be heated to form a molten state and entering in a pipeline mould, forming a thermoplastic state pipeline through pulling, carrying out number jet printing on a pipe to be pulled; 2, carrying out two sections of water cooling on the pipeline to ensure that the pipeline becomes an elastic pipeline, wherein water temperatures of the two sections of water cooling are respectively kept between 60 DEG C and 70 DEG C and between 40 DEG C and 50 DEG C; 3, cutting the elastic pipeline according to a certain length to manufacture a number ring; and 4, at an environment temperature of 20-25 DEG C, sleeving the number ring with the temperature kept between 40 DEG C and 50 DEG C on an optical cable, and when the number ring is cooled to the environment temperature, tightly sleeving the number ring on the optical cable. The invention has the benefial effects that the mold shrinkage is technically controlled by using the characteristics of materials made into the number ring, and the purposes of tight matching with the cable and wiring identification can be achieved, and no sliding and rotating phenomena exist between the number ring and the cable.
Description
Technical field
The present invention relates to a kind of figure ring production and the method being tightly placed on optical cable, are applied to fiber optic cable manufacture technical field
In.
Background technology
At present common practice in the industry is the figure ring using short cylindrical hollow form made by plastics, is set on during distribution little
On the tight sleeve optic cable of size, but this scheme can cause figure ring to slide and rotate on optical cable, coding occur and show the feelings such as entanglement
Condition, to assembling and later maintenance certain difficulty is brought.Solution is provided in many published patents such as：Application No.
The patent of the U of CN 201707839 describes a kind of structure improved figure ring, and it is the fixture block in inverted U, in the opening of fixture block
The both sides at end, towards the anti-skidding sharp bar of twice that the internal face of blind end is formed with the distribution that is at right angles, make fixture block not tend to have and turn over
Turn situation；The patent of Application No. 200920005508.5 describes a kind of figure ring, and its section is trapezoidal, and four are adopted in inner chamber
Bar is symmetrical and elastic rib is fixing, and it is mounted on cable can effectively anti-sliding stop and rotation.This two patents
Described figure ring is set on 0.9mm tight sleeve optic cables can cause cable jacket stress to deform upon, so as to cause optical cable
Inner fiber is squeezed, and transmission performance is deteriorated, and serious situation can cause that optical fiber is impaired to rupture.
The content of the invention
The present invention is overcoming the deficiencies in the prior art, there is provided a kind of figure ring production and the method being tightly placed on optical cable, its
Concrete technical scheme is as follows：
A kind of figure ring production and the method being tightly placed on optical cable, comprise the steps：1）By polytetrafluoroethylplastic plastic
Grain is put in correspondence heating furnace and is heated to 330～380 DEG C, and in molten pipeline mould is entered, and is formed in the mould extrusion
The pipeline of thermoplastic character, draws to the pipeline, and carries out number spray printing to the pipeline outer surface； 2）It is printed on above-mentioned
The pipeline of the thermoplastic character of number carries out two sections of water-cooleds, and it is 1.48-1.52mm to make pipe external diameter, and pipe thickness is 0.255-
The bullet state pipeline of 0.265mm, the water temperature of first paragraph water-cooled is maintained at 60～70 DEG C, and the water temperature of second segment water-cooled is maintained at 40～50
℃；3）The bullet state pipeline is carried out into cutting by certain length, the number that outer surface contains number described at least one is made
Ring；4）In the case where ambient temperature is for 20-25C °, the figure ring for keeping the temperature at 40-50C ° is set on mark required for optical cable
Position, when figure ring is cooled to the ambient temperature, figure ring radial shrinkage ratio makes number up to 5%～8% using the shrinkage factor
Ring is tightly placed on optical cable.
The production and the further design of the method for assembling tight sleeve optic cable figure ring are, under the hot plastic state
The hauling speed of pipeline is 5～20m/min.
The control that the inventive method passes through the associated process conditions in ring processing technology of checking numbers, makes up to required receipts
Shrinkage, thus makes figure ring be tightly placed on corresponding optical cable；Because force in radial is uniform in contraction process, and lifting surface area
Greatly, so extrusion damage will not be caused to optical cable；The figure ring being tightly placed on optical cable simultaneously will not slide or relative on optical cable
Optical cable is rotated, so figure ring position on optical cable keeps stable.
