Abstract
The utility model discloses an imporous optical cable production device, which comprises a die sleeve and a die core, wherein a die sleeve cavity is arranged in the die sleeve; the die core is in the die sleeve cavity; a die core cavity is arranged in the die core; an extrusion ring is also arranged at one side of the die sleeve cavity; and the diameter of the die core cavity is not less than that of the extrusion ring. According to the utility model, the extrusion ring is arranged at one side of the die sleeve; the die core cavity corresponding to the extrusion ring is arranged in the die core; therefore, same shapes of jackets can be obtained in the extrusion process; and the phenomenon that small holes exist in the optical cable machining process can be avoided.
Description
Technical field
The utility model relates to the optical cable processing technique field, particularly a kind of atresia optical cable process units.
Background technology
At present; optical cable manufacturer produces optical cable; (it is by the sleeve pipe of Φ 2.8mm such as GYXTW; 2 Φ 1.2mm steel wires and waterstop form) invar silk lap-joint and PE overlap the stress reason between the materials in the tube; in process of production; diameter often can appear on the pipe box less than the aperture of 1mm; and the discontinuous existence of aperture; it can keep a segment distance (3m) not seep water in 24 hours when in use; although it can satisfy general request for utilization; but along with the requirement of industry interior focusing cable is more and more higher, having or not of this kind aperture also becomes one of acceptance criteria accordingly.By analyzing as can be known, the factor that affects the existence of optical cable aperture mainly contains following two aspects, the one, the Design of Dies of sheath is undesirable, it two is that the technique of optical cable in process is perfect not, and processing technology is subject to manual control fully, therefore on the good basis of technology controlling and process, the Design of Dies of sheath becomes and improves the important reforming direction that aperture has or not on the optical cable.
Therefore how designing novel atresia optical cable process units removes the aperture in the optical cable and becomes one of problem that fiber optic cable production enterprise need to solve.
The utility model content
The purpose of this utility model is to provide a kind of atresia optical cable process units that does not produce the die sleeve aperture in the optical cable process.
In order to solve problem set forth above, the utility model adopts following technical scheme: a kind of atresia optical cable process units, comprise die sleeve and core rod, described die sleeve is provided with the die sleeve chamber, described core rod is positioned at described die sleeve chamber, described core rod is provided with mold core cavities, and described die sleeve chamber one side also is provided with extrudes ring, and the diameter of described mold core cavities is not less than the described diameter of extruding ring.
Atresia optical cable process units of the present utility model, preferred, the cross sectional shape in described die sleeve chamber is trapezoidal, near the diameter of extruding ring one side less than away from the diameter of extruding ring one side.
Atresia optical cable process units of the present utility model, preferably, described mold core cavities comprises mold core cavities leading portion and mold core cavities back segment, described mold core cavities back segment is that diameter is not less than described the cylindrical of ring diameter of extruding, the cross sectional shape of described mold core cavities leading portion is trapezoidal, and the diameter of close mold core cavities back segment one side is less than the diameter away from mold core cavities back segment one side.
Atresia optical cable process units of the present utility model, preferred, described die sleeve 1 one ends comprise the die sleeve flange, and described core rod one end comprises the core rod flange corresponding with described die sleeve flange, and described die sleeve flange is connected with the core rod flange bolt.
Compared with prior art, the beneficial effects of the utility model are: be provided with in a side of die sleeve and extrude ring and be provided with the mold core cavities corresponding with extruding ring in core rod, so that sheath can access consistent shape in extrusion, therefore can avoid in the optical cable process, occurring the phenomenon of aperture.

Embodiment
Below in conjunction with embodiment and accompanying drawing the utility model is described in further detail, but embodiment of the present utility model is not limited to this.
Shown in Fig. 1-5, the utility model provides a kind of atresia optical cable process units, comprise die sleeve 1 and core rod 2, described die sleeve 1 comprises die sleeve chamber 8, described core rod 2 is positioned at described die sleeve chamber 8, described core rod 2 comprises mold core cavities 9, and described die sleeve chamber 8 one sides also are provided with extrudes ring 3, and the diameter of described mold core cavities 9 is not less than the described diameter of extruding ring 3.
In the utility model, the cross sectional shape in described die sleeve chamber 8 is trapezoidal, near extrude the ring 3 one sides diameter less than away from extrude the ring 3 one sides diameter.
In addition, described mold core cavities 9 comprises mold core cavities leading portion 6 and mold core cavities back segment 7, described mold core cavities back segment 7 is described the cylindrical of ring 3 diameters of extruding for diameter is not less than, the cross sectional shape of described mold core cavities leading portion 6 is trapezoidal, and the diameter of close mold core cavities back segment 7 one sides is less than the diameter away from mold core cavities back segment 7 one sides.
Installation and the course of work of atresia optical cable process units of the present utility model are: core rod 2 is installed on the sheath extruding machine of optical cable, then die sleeve 1 is installed on the core rod 2, and die sleeve 1 one ends are provided with die sleeve flange 4, be provided with the core rod flange 5 corresponding with described die sleeve flange 4 at core rod 2 one ends, wherein die sleeve flange 4 is connected with core rod flange 5 bolts, and in the installation process of die sleeve 1, with mold core cavities back segment 7 with extrude the ring 3 corresponding; When at extrusion molding, the sheath cable is successively by mold core cavities leading portion 6 and mold core cavities back segment 7, encircle 3 extrusion moldings by extruding at last, and in the utility model, because die sleeve 1 is fixed with core rod 2, namely do not need to do any adjustment, can directly produce processing in batches, by adopting sheath that this method processes in the process of optical cable, have preferably usability, it is difficult for producing the optical cable aperture, has improved the overall quality of optical cable.
