A kind of manufacturing method of air-blowing pipeline

The application is entitled：A kind of manufacture cable is with the system of air-blowing pipeline and manufacturing method, the applying date：2014 May 26, application No. is：The divisional application of 2014102244405 patent of invention.

Technical field

The invention belongs to pipe technology field, system and manufacturer more particularly, to a kind of manufacture cable with air-blowing pipeline Method.

Background technology

With the rapid development of the industries such as electric power, communication, the laying amount of cable is more and more, on the one hand, due to big in the past For the cable of amount using aerial laying, therefore, aerial cable is very in disorder, affects city appearance, meanwhile, it brings greatly Security risk；For this purpose, country has promulgated corresponding law, regulation and instruction, need to carry out cable by the way of entering ground Laying.Cable mainly has poling and direct-buried mode in underground laying, and direct-buried mode needs to dig ground, and multiple tracks is needed to examine Formality, it is therefore, cumbersome；For this purpose, pipeline laying mode will be the principal mode of later underground laying.

In the larger caliber pipeline laid for underground, smaller for diameter and smooth in appearance cable, in pipeline In have and can directly carry out drawing laying when sufficient space, still, drawing cable laying operation progress is relatively slow and is easy to influence cable Cable is taken out once the quality of cable is damaged in construction or the cost of restorability is just very huge by quality, especially optical cable Greatly.

For larger city, existing cable pipeline resource pretty nervous usually rents 1KM about 18mm diameters Pipeline, annual price is at 200,000 yuan or so, therefore, fairly expensive；Nonetheless, the operator in also many areas and non-fortune Battalion quotient influences the progress of engineering because renting less than pipeline resource, or even what is had can only abandon original engineering.

For this purpose, expecting that there is preferable solution in industry, there can be the pipeline of excess room in underground.But it is domestic Therefore the outer file effectively reported without producing the system of air-blowing pipeline relatively expects the appearance of related system in industry.

Temperature control system is used to control the extrusion temperature of extruding machine, meanwhile, which can also have receipts, comb system System, printing system etc., due in temperature control system, trailer system, receipts/pipe system, printing system and existing cable technique Sheathed cable extruder it is identical, therefore be not described in detail.

Embodiment 2

See Fig. 8 to Fig. 9, and referring to figs. 1 to Fig. 7, a kind of system of manufacture cable air-blowing pipeline, with embodiment 1. The difference is that the manufacturing method of air-blowing pipeline, the first step, by the air-blowing tube body of straightened condition to air-blowing pipe convex Body and air-blowing pipe diversion trench to slightly doubling, then air-blowing tube body penetrates closing in channel, is then passed through the hole inside calibration tube, connects It across mold core hole and draws air-blowing tube body, and plunger is made to be located inside air-blowing tube body, make sizing end air-blowing tube body Both sides joint is located at fixed slot, carries out Hot-blast Heating using heat gun at fixed slot, makes to be bonded together shape at docking At the fin 6 for protruding from air-blowing tube body lower surface；Second step, opens extruding machine, and plastics enter mold core and mould in extrusion head In the gap of set, upper exterior tube body 7 is extruded outside air-blowing tube body 5；Trailer system traction outer tube body enters cooling system progress It is cooled into air-blowing pipeline.

Due to the presence of fin so that when extruding upper exterior tube body 7 outside air-blowing tube body, fin 6 is located in outer tube body 7 Therefore portion even if being sticked to outside air-blowing tube body without using viscose glue, can also make the air-blowing tube body be with outer tube body firm connection One has excellent anti-torsion, bending resistance.

Air-blowing tube body and outer tube body all use high-density polyethylene material, form air-blowing pipeline, repeatedly around putting 238 times, The segregation phenomenon of the gentle blowpipe ontology of air-blowing pipe outer tube body is there are no, and could be used without the air-blowing tube body of fin and outer tube is made Air-blowing pipeline, laying 3 times repeatedly, there have been the air-blowing tube bodies of many places and outer tube body lamination；It is not convex when production The air-blowing pipeline of rib is equally carried out laying experiment, be also only subjected to after carrying out air-blowing tube body with outer tube body bonding using viscose glue 12 experiments are lived, there have been layerings at the 13rd time；It is coated simultaneously outside the air-blowing tube body in this embodiment viscous The air-blowing pipeline formed after glue there are no the segregation phenomenon of the gentle blowpipe ontology of air-blowing pipe outer tube body repeatedly around putting 325 times；Cause This, the air-blowing pipeline manufactured using the system and method for this embodiment has more excellent resistance to torsion, folding quality.

Embodiment 3

See Figure 10, and referring to figs. 1 to Fig. 9, a kind of system of manufacture cable air-blowing pipeline, with embodiment 1.It is different One of place is system：Knot installation is installed between sizing end 101 and extrusion head 131, since knot installation is existing In cable processing technology, especially SZ twisted synthesizing cables therefore the common technology of bundling machine class is not drawn on the diagram.

According in above system difference, therefore the two of the difference manufacturing methods for being air-blowing pipeline：Air-blowing tube body into Before the mold core hole 132 for entering extrusion head, is wrapped up outside air-blowing tube body and tie up element 9.

Tie up element and can be effectively prevented air-blowing tube body and scatter, meanwhile, air-blowing tube body is micro- melt state under, tie up member Part, which is absorbed in, to be tied up in air-blowing tube body, on the other hand, can coat viscose glue on air-blowing tube body surface, the air-blowing pipe being extruded into this way Road also has excellent resistance to twisting energy, also has been subjected to 250 torsion tests, after torsion and has no air-blowing pipeline cracking and divides Layer.

Certainly, in system of the invention, extrusion head can not be supported completely by third support column namely third support Column can be omitted completely, as long as extrusion head is combined with extrusion molding fuselage enough to secured.

The present invention is not limited to above-mentioned preferred forms, it should be understood that design of the invention can be by other various shapes Formula is implemented to use, they also fall in protection scope of the present invention.
