Abstract
The invention relates to a cable manufacturing method for ensuring roundness of a marine cable and easy peeling of a sheath. The cable manufacturing method sequentially comprises the following steps of: filling gaps among a plurality of insulating wire cores with loose fibers and then stranding into an insulating core wire bundle; winding and wrapping in a lapped manner by employing nonhygroscopic wrapping belts and then forming a cable; extruding and wrapping the sheath at the periphery of the cable by using a semi-extruding semi-tube-extruding mould; heating a cable material until being completely molten and wrapping the molten cable material around the cable; blowing air in the cable at the cable inlet end of a sheath extruding mould by employing a blast blower, wherein the size of wind power just allows the loose fibers filled in the cable to be completely swelled and tightly attached to the nonhygroscopic wrapping belts, so that the entire cable is round; extruding and wrapping the molten cable material at the periphery of the round cable swelled by the air along with the advancing of the cable; arranging a water cooling slot at the position spaced from the outlet end of the sheath extruding mould in a distance of 20-30 cm; after the cable is towed out of the sheath extruding mould, putting the cable in a cooling slot for cooling; and keeping the round state of the cable when the sheath is extruded.
Description
Technical field
The present invention relates to a kind of cable making method, particularly a kind of cable making method of guaranteeing that shipboard cable rounding and sheath are prone to peel off.
Background technology
Shipboard cable comprises many insulated core, is twisted into the insulating core wire harness after the slit between many insulated core is filled, and adopts the wrapped back of non-hygroscopic band eclipsed form to form cable in insulating core wire harness periphery, outside cable, extrudes oversheath.Extrude that three kinds of moulds are arranged on the oversheath market is plsitive mold, tubular molding tool and partly push half tubular molding tool; It is inhomogeneous that wherein jacket thickness appears extruding in plsitive mold easily; The loose drawback of owing compactness of sheath appears extruding in tubular molding tool easily; Can overcome above drawback and partly push half tubular molding tool, make the jacket thickness that extrudes evenly compact.
Receive the boats and ships limited space, require shipboard cable necessary soft.From the cable seal angle, the necessary rounding of cable, the cable of rounding is peeled off sheath easily.Though cable is filled when stranding at present, or can't realize the cable rounding fully, or rely on super large pressure to realize rounding.Rely on super large pressure to realize that the cable of rounding is difficult to cable cover(ing) is peeled off, the inconvenience construction is laid.
Summary of the invention
The objective of the invention is to, overcome the problem that exists in the prior art, a kind of cable making method of guaranteeing that shipboard cable rounding and sheath are prone to peel off is provided.
For solving above technical problem; A kind of cable making method of guaranteeing that shipboard cable rounding and sheath are prone to peel off provided by the present invention may further comprise the steps successively: (1) is twisted into the insulating core wire harness with the slit between many insulated core after with loose shape fiber filled; (2) adopt the wrapped back of non-hygroscopic band eclipsed form to form cable in said insulating core wire harness periphery; (3) extrude sheath in said cable periphery; At first said cable is passed jacket extrusion mould through draw-gear when extruding sheath; Then CABLE MATERIALS is heated until complete molten; And the CABLE MATERIALS that makes fusion is wrapped in around the said cable, and said jacket extrusion mould is half extruding, half tubular molding tool; (4) at the cable arrival end of said jacket extrusion mould, adopt the air blast of transferring the files that wind is blown in the said cable, the wind-force size be able to make the complete rising of loose shape fiber of filling in the said cable be close to said non-hygroscopic band to make cable integral body be the rounding shape; Along with advancing of said cable, the CABLE MATERIALS of fusion is extruded in the cable periphery of being heaved rounding by wind; (5) place water-cooling groove at the port of export 20～30cm place, after said cable is pulled out said jacket extrusion mould, gets into said cooling bath and cool off, the rounding state when keeping cable cover(ing) to extrude from said jacket extrusion mould.
With respect to prior art; The present invention has obtained following beneficial effect: adopt loose shape fiber filled between insulated wire cores; The slit of loose shape fibrous inside is beneficial to wind and gets into cable inside; The shape fiber that under wind, loosens is easy to fluffy, is close to the non-hygroscopic band behind the loose shape fiber fluffy and makes cable integral body be the rounding shape; When the CABLE MATERIALS of fusion was extruded in the cable periphery, wind-force also played the supplemental support effect, prevented that the non-hygroscopic band receives the gravity effect of self and CABLE MATERIALS and is out of shape; It is inhomogeneous that jacket thickness appears extruding in plsitive mold easily, and the loose drawback of owing compactness of sheath appears extruding in tubular molding tool easily, can overcome above drawback and partly push half tubular molding tool, makes the jacket thickness that extrudes evenly compact.After the CABLE MATERIALS of molten is extruded in the cable periphery; Under the influence of gravity, can slowly flow downward, make the wall thickness reduction on top, the wall thickness of bottom increases; The present invention places water-cooling groove at the port of export 20～30cm place from jacket extrusion mould; After cable is pulled out jacket extrusion mould, in time get into cooling bath cool off and obtain the typing, the rounding state in the time of can keeping cable cover(ing) to extrude.
As preferred version of the present invention, said loose shape fiber is netted polypropylene split fibre.
As preferred version of the present invention, said loose shape fiber is the netted polypropylene fibre of flame-retardant expanded type.
Embodiment
The present invention guarantees the cable making method that shipboard cable rounding and sheath are prone to peel off; May further comprise the steps successively: (1) is twisted into the insulating core wire harness with the slit between many insulated core after with loose shape fiber filled, and loose shape fiber is preferably netted polypropylene split fibre or the netted polypropylene fibre of flame-retardant expanded type; (2) adopt the wrapped back of non-hygroscopic band eclipsed form to form cable in said insulating core wire harness periphery; (3) extrude sheath in said cable periphery; At first said cable is passed jacket extrusion mould through draw-gear when extruding sheath; Then CABLE MATERIALS is heated until complete molten; And the CABLE MATERIALS that makes fusion is wrapped in around the said cable, and said jacket extrusion mould is half extruding, half tubular molding tool; (4) at the cable arrival end of said jacket extrusion mould, adopt the air blast of transferring the files that wind is blown in the said cable, the wind-force size be able to make the complete rising of loose shape fiber of filling in the said cable be close to said non-hygroscopic band to make cable integral body be the rounding shape; Along with advancing of said cable, the CABLE MATERIALS of fusion is extruded in the cable periphery of being heaved rounding by wind; (5) place water-cooling groove at the port of export 20～30cm place, after said cable is pulled out said jacket extrusion mould, gets into said cooling bath and cool off, the rounding state when keeping cable cover(ing) to extrude from said jacket extrusion mould.
Except that the foregoing description, the present invention can also have other execution modes.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop in the protection range of requirement of the present invention.
