Abstract
The invention discloses an aluminium tape longitudinal wrapping forming die for production of optical cables. The aluminium tape longitudinal wrapping forming die comprises a frame (13), and a longitudinal wrapping die (1) and a sizing die (2) that are disposed on the frame (13). The longitudinal wrapping die (1) includes a die body (3) with an arc cross section, one end of the die body (3) is bent to be round, and the round end of the die body (3) is hooped by a circular ring (4). The sizing die (2) includes a circular ring die holder (7) and a sizing mold (8) arranged thereinside, and a tapered hole (9) is disposed in the sizing mold (8). The beneficial effects of the forming die are that the die body of the longitudinal wrapping die is designed to be arc-shaped, so that a contact area between the die and an aluminium tape is reduced; small holes are disposed at one end of a longitudinal wrap, so that a contact area between the longitudinal wrap and the aluminium tape is reduced; and the hole is also arranged in the sizing mold, so that frictional force between the aluminium tape and the die is greatly reduced, the aluminium tape is protected from being pulled apart and the production efficiency is improved.
Description
Technical field
The present invention relates to mould for aluminum band longitudinal wrapping in a kind of optical cable production.
Background technology
Fibre Optical Communication Technology (optical fiber communications) is shown one's talent from optical communication, has become one of main pillar of modern communications, plays a part very important in Modern Telecommunication net.Optical fiber communication is as an emerging technology, fast, the application surface of its development in recent years speed be extensively that communication is rarely seen in history, be also the main means of transportation of various information in the important symbol of new worldwide technological revolution and Future Information society.
Optical fiber is fibre-optic abbreviation.Optical fiber communication is to using light wave as information carrier, usings a kind of communication mode of optical fiber as transmission medium.
During optical cable is produced, generally can on cable core, wrap up one deck aluminium strip, enhancement Layer for optical cable, the resistance to compression and the water repelling property that improve optical cable, aluminium strip layer is generally made by mould in optical cable process, has comprised longitudinal covering model tool and sizing die, and longitudinal covering model tool and sizing die are all to twist and squeezing action makes the aluminium strip moulding that twists by machinery, existing mould because and aluminium strip between friction too large, aluminium strip is often pulled off, greatly affected speed of production.
Summary of the invention
Object of the present invention is to overcome the deficiency of present technology, provide a kind of optical cable produce in mould for aluminum band longitudinal wrapping, solving existing bundling machine, to change yarn group frequency high, the drawback that impact is produced.
The present invention is achieved through the following technical solutions: mould for aluminum band longitudinal wrapping in optical cable production, comprises frame and rack-mounted longitudinal covering model tool and sizing die;
Described longitudinal covering model tool comprises die body, and described die body is arc, and die body to have one end to twist circular, the round nose of die body is fixed by annulus hoop, is provided with at least two straight plates in the deep-slotted chip breaker of die body, on straight plate, is provided with cable core conduit;
Described sizing die is arranged on longitudinal covering model Ju rear along cable core transmission direction, comprise annulus die holder and be arranged on the plug die in annulus die holder, in described plug die, be provided with a bellmouth, the center of bellmouth is over against the center with die body round nose, and the tapering of bellmouth is 3 °～15 °.
Described die body is arranged in frame by installing plate.
The round nose of described die body is distributed with anti-attrition hole.
Described cable core conduit is welded and fixed by welding bar.
On described plug die, distribute porose.
The invention has the beneficial effects as follows: the die body of longitudinal covering model tool is designed to arc; reduced the surface of contact with aluminium strip; Zong Bao one end is design arrangement aperture also; also reduced the surface of contact with aluminium strip; and on plug die, be also furnished with aperture; so greatly reduced the friction force between aluminium strip and mould, protection aluminium strip is not pulled off, and has improved production efficiency.

Embodiment
Below in conjunction with embodiment, the present invention is described in further detail, but structure of the present invention is not limited only to following examples:
[embodiment]
As shown in Figures 1 to 3, mould for aluminum band longitudinal wrapping in optical cable production, comprises frame 3 and is arranged on longitudinal covering model tool 1 and the sizing die 2 in frame 13;
Described longitudinal covering model tool 1 comprises die body 3, and described die body 3 is arc, and die body 3 to have one end to twist circular, the round nose of die body 3 is fixed by annulus 4 hoops, is provided with at least two straight plates 5 in the deep-slotted chip breaker of die body 3, on straight plate 5, is provided with cable core conduit 6;
Described sizing die 2 is arranged on the rear of longitudinal covering model tool 1 along cable core transmission direction, comprise annulus die holder 7 and be arranged on the plug die 8 in annulus die holder 7, in described plug die 8, be provided with a bellmouth 9, the center of bellmouth 9 is over against the center with die body 3 round noses, and the tapering of bellmouth 9 is 3 °～15 °.
Described die body 3 is arranged in frame 13 by installing plate 11.
The round nose of described die body 3 is distributed with anti-attrition hole 10, distributes porose 14 on plug die 8, for decreasing in the surface of contact of aluminium strip, thereby reduces friction, protection aluminium strip.
Described cable core conduit 6 is welded and fixed by welding bar 12.
Principle of work of the present invention: during production, cable core penetrates cable core conduit 6, enter the round nose of die body 3, aluminium strip, from passing and also enter round nose between straight plate 5 and die body 3, is twisted during by round nose circular, and in the middle of cable core is wrapped in, so just completed basic vertical packet procedures, can be admitted to afterwards in sizing die 2, by the bellmouth 9 of plug die 8, aluminium strip is further slaped tightly, made aluminium strip can wrap up cable core completely.
