Abstract
The utility model provides a sheath extrusion die for realizing a self-supporting cable applied with water ointment, which comprises an extrusion die, wherein the inlet end surface of the extrusion die is provided with a principal line die hole and a self-supporting line die hole, the inlet end of the self-supporting line die hole is provided with a counter hole which is internally provided with a thin metal conduit; and the thin metal conduit is connected with the self-supporting line die hole in a sealing way. The sheath extrusion die utilizes the metal conduit to isolate a self-supporting line and a core line applied with ointment completely, meets the one-time synchronous completion of processes of ointment applying, core line protection layer, self-supporting line sheath and the like in the process of ointment applying of a principal line, and realizes high-efficiency production of a self-supporting cable applied with water resistant ointment.
Description
Technical field
The utility model belongs to field of cables, relates in particular to a kind of jacket extrusion mould that is used to realize be coated with the self-supporting cable of water ointment.
Background technology
The heart yearn of the self-supporting cable of outdoor use is all less than applying the moistureproof ointment that blocks water at present, the heart yearn gas cut that very easily makes moist is gone into and is worsened the performance index of cable, and its main cause is that heart yearn applies ointment, heart yearn sheath, self-supporting steel wire sheath disposable to finish technology difficulty bigger in sheath operation high-speed synchronous.Because ointment is liquid condition, ointment can laterally flow into the nib of self-supporting line from main line nib inlet section part when the cable core of coating ointment and self-supporting steel wire entered extrusion die at the same time, make self-supporting steel wire bonding ointment cause main line to separate, cause scrapping of cable with self-supporting line articulamentum.
Summary of the invention
The utility model provides a kind of jacket extrusion mould that is used to realize be coated with the self-supporting cable of water ointment, has solved that self-supporting steel wire bonding ointment causes main line to separate the shortcoming that causes cable to scrap with self-supporting line articulamentum in the background technology.
The technical solution of the utility model is achieved in that a kind of jacket extrusion mould that is used to realize be coated with the self-supporting cable of water ointment, comprise extrusion die, the entrance face of extrusion die is established main line nib and self-supporting line nib, arrival end at self-supporting line nib is established counterbore, establishes thin metallic-pipe in the counterbore;
Thin metallic-pipe and self-supporting line nib are tightly connected.
The beneficial effects of the utility model are: the utility model isolates self-supporting line and the heart yearn that applies ointment by metal catheter fully, add in the process of ointment at main line, satisfy ointment coating, heart yearn sheath, self-supporting line sheath etc. technology is disposable and finished synchronously, realized applying the high efficiency production of the self-supporting cable of greasy for preventing water.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Part explanation: 1, self-supporting line nib, 2, the main line nib, 3, thin metallic-pipe, 4, counterbore, 5, extrusion die.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described: a kind of jacket extrusion mould that is used to realize be coated with the self-supporting cable of water ointment, comprise extrusion die 5, the entrance face of extrusion die 5 is established main line nib 2 and self-supporting line nib 1, arrival end at self-supporting line nib 1 is established counterbore 4, establish thin metallic-pipe 3 in the counterbore 4, thin metallic-pipe 3 is tightly connected with self-supporting line nib 1.The self-supporting steel wire enters extrusion die from thin metallic-pipe 3 during production, the heart yearn that has a greasy for preventing water is during by main line nib 2, unnecessary ointment is because the adding of thin metallic-pipe 3, the self-supporting line is effectively separated with the heart yearn of band ointment, thereby guarantee that the heart yearn ointment can not be bonded to the self-supporting steel wire, guarantees the ordinary production of this cable.
Claims (2)
1. jacket extrusion mould that is used to realize be coated with the self-supporting cable of water ointment, comprise extrusion die (5), the entrance face of extrusion die (5) is established main line nib (2) and self-supporting line nib (1), it is characterized in that establishing counterbore (4), establish thin metallic-pipe (3) in the counterbore (4) at the arrival end of self-supporting line nib (1).
