Abstract
The utility model discloses a steel plastic bonding integrated sheath cable sizing mould set, which comprises more than two sizing moulds, a sizing hole is arranged in each sizing mould in the axial direction, the sizing hole is formed by a tapering conical inlet and a cylindrical line-bearing hole, wherein the tapering conical inlet and the cylindrical line-bearing hole are communicated. The diameter and length of the line-bearing hole in each sizing mould taper in the passing direction of a cable core. The sizing mould set is utilized to implement a novel longitudinal covering method, and a longitudinal covering steel band utilizes more than two sizing moulds to undergo slight deformation step by step when passing the sizing mould set so that the deformation stress of the steel band is small when the steel band passes each sizing mould. Accordingly, the fact that lotus-leaf-shaped cracks exist on the edge of the longitudinal covering steel band in a steel band longitudinal covering process is eliminated, steel band longitudinal covering quality is ensured, and the passing rate of products is increased.
Description
Technical field
The utility model belongs to the cables manufacturing field, and definite a kind of steel that is used for of saying so is moulded the sizing set of molds that the vertical bag of stainless steel band is carried out in bonding composite-sheathed cable production.
Background technology
For increasing the intensity of local cable, prevent the destructions of pecking at such as woodpecker, need outside cable core, indulge bag one deck stainless steel band and process the anti-woodpecker cable; Vertical bag stainless steel band is mainly realized through plug die in the prior art; But existing plug die is mainly used in flexible big materials such as aluminium-plastic tape, and it is in vertical Baogang band engineering, because the hardness of steel band is big, deformability is poor; The edge of steel band as easy as rolling off a log wrinkling appearing " lotus leaf line " phenomenon; Thereby invar band sheath coats and closely causes a large amount of cable waste products, and rate of finished products is low, and it is higher to cause this steel to mould the production cost of bonding composite-sheathed cable.
The utility model content
The purpose of the utility model is: provide a kind of steel to mould bonding composite-sheathed cable sizing set of molds, mould the low problem of bonding composite-sheathed cable vertical bag stainless steel band rate of finished products to solve existing steel.
The technical scheme that the utility model steel is moulded bonding composite-sheathed cable sizing set of molds is: a kind of steel is moulded bonding composite-sheathed cable sizing set of molds; It is made up of plural plug die; The axial respectively metering hole that offers in each plug die; Described metering hole holds the line hole by diminishing conical inlet and columniform and is interconnected and forms, and aperture of holding the line hole and hole length in said each plug die are dwindled along the cable core direction of passage successively.
The aperture of holding the line hole of one plug die in back is held at preceding one plug die on the basis in aperture, line hole and is reduced by 0.15 ~ 0.3mm in said each plug die, and its hole length shortens 15 ~ 25mm preceding holding together on the long basis, hole, line hole.
The aperture of holding the line hole of one plug die in back is held at preceding one plug die on the basis in aperture, line hole and is reduced 0.2mm in said each plug die, and its hole length shortens 20mm preceding holding together on the long basis, hole, line hole.
The aperture of holding the line hole that is positioned at the plug die in first road in described each plug die is the surplus of on the basis of conductor assembly outer diameter, adding 1.5 ~ 2.0mm.
The length of holding the line hole that is positioned at the plug die in first road in described each plug die is 150mm.
The end diameter of the taper shape inlet of said each plug die equates that with the aperture of holding the line hole of corresponding connection its outside diameter is added 20mm for the corresponding aperture, line hole of holding.
After the utility model was implemented new vertical bag method through the sizing set of molds, vertical Baogang band utilized plural plug die to make steel band divide the distortion of order small-amount through the sizing set of molds time; Make that the distortional stress of steel band through each plug die the time is all very little; Thereby eliminated the phenomenon that the lotus leaf line appears in its edge in the vertical packet procedures of steel band, guaranteed the quality of the vertical bag of steel band, improved product percent of pass; And adopt two above plug dies reduced steel band through the time frictional force; It has reduced in the production process pulling force to cable, thereby has reduced the power consumption of equipment, has improved production efficiency accordingly and has reduced production cost.

Fig. 2 is the structural representation of the first road plug die among Fig. 1.
Embodiment
The steel that is used for of the utility model is moulded vertical sizing set of molds such as the Fig. 1, shown in Figure 2 that wraps usefulness of bonding composite-sheathed cable; This sizing set of molds is formed along the coaxial plug die that sets gradually 3 ~ 7 of cable core 1 direction of advance by five; With the first road plug die 3 is example; Be respectively equipped with in each plug die 3 ~ 7 by being communicated with the metering hole that constitutes along diminishing conical inlet 30 of cable core direction of advance and the columniform line hole 31 of holding; Aperture d that holds the line hole and the long L in hole in each plug die 3 ~ 7 successively decrease along the direction of advance of cable core gradually; Wherein, the aperture d that holds line hole 31 in the first road plug die 3 is the surplus that on the basis of cable core 1 external diameter, adds 1.5 ~ 2.0mm, the 0.15 ~ 0.3mm that on the basis in the aperture of holding line hole 31 of the first road plug die 3, successively decreases successively of the aperture d that holds the line hole in follow-up each plug die 4 ~ 7; Simultaneously, the hole length of holding the line hole in follow-up each plug die 4 ~ 7 is held the 15 ~ 25mm that successively decreases successively on the basis in line hole 31 at the first road plug die 3.In the present embodiment; The aperture d that holds the line hole in the first road plug die 3 is 8.5mm, Kong Changwei 150mm; The aperture of holding the line hole in follow-up each plug die 4 ~ 7 0.2mm that successively decreases successively, the aperture of holding the line hole in its follow-up each plug die 4 ~ 7 respectively is and is 8.3mm, 8.1mm, 7.9mm, 7.7mm; Hold the long 20mm that successively decreases successively in hole in line hole in follow-up each plug die 4 ~ 7, the hole length of holding the line hole in follow-up each plug die 4 ~ 7 respectively is 130mm, 110mm, 90mm, 70mm.
The steel of the utility model is moulded the vertical bag method of bonding composite-sheathed cable for cable core 1 outer vertical Baogang is passed through the plug die more than the twice successively after 2, and aperture of holding the line hole and hole length in the plug die are dwindled along the cable core direction of passage successively.In the present embodiment, adopt five road plug dies 3 ~ 7, each plug die 3 ~ 7 aperture d concrete structure is existing in the above-described embodiments to be described in detail, repeats no more here.The utility model makes to form the distortion that divides the order small-amount when steel band passes through the per pass plug die owing to adopt the multiple tracks plug die, makes that the distortional stress of steel band through each plug die the time is all very little; Distortional stress discharges easily, has guaranteed lotus leaf line limit not occur behind the strip deformation, and the outward appearance rounding of steel band sheath is bright and clean; Guaranteed the quality of the vertical bag of steel band; Improved product percent of pass, and adopt two above plug dies reduced steel band through the time frictional force, it has reduced in the production process pulling force to cable; Thereby reduced the power consumption of equipment, improved production efficiency accordingly and reduced production cost.
