Abstract
The utility model discloses an aluminum conductor pressing device for insulated cable manufacturing. The device comprises a wire doubling mold, a horizontal pressure roller, a vertical pressure roller, a press drawing die and a silicone oil dropping device, wherein the wire doubling mold, the horizontal pressure roller, the vertical pressure roller and the press drawing die are arranged on the outer surface of an outer aluminum monofilament sequentially from left to right, the silicone oil dropping device is arranged above the press drawing die, and the silicone oil dropping device is provided with an infusion tube. The device breaks the traditional method of using a single pressure roller device or a single press drawing die device to press a wire core into a round shape and effectively integrates the pressure roller device and the press drawing die device. Silicone oil is tasteless and non-toxic and has certain lubricating and cooling effects on press drawing, the production of aluminum scraps is greatly reduced, extrusion molding is not influenced, produced conductor wire cores are round and contains only a small amount of aluminum scraps, the electrical properties of cables are not affected, and the insulation performance of cables is improved. The aluminum conductor pressing device for insulated cable manufacturing is applicable to products such as low-voltage cable, 10kV cross-linked cables, overhead insulated conductors, low-voltage flame-retardant cables, 10kV flame-retardant cross-linked cable or the like.
Description
Technical field
The utility model relates to the electric wire and cable conductor manufacture field, relates in particular to a kind of insulated cable manufacturing aluminium conductor compacting device.
Background technology
The circular compacting device of the stranded aluminium conductor of electric wire has two kinds at present, and a kind of is press-roller device, is all generally to adopt two secondary pressure roller shuntings to carry out.First is horizontal pressure, and second is pressed for vertical, and the 3rd road is horizontal pressure, and the 4th road is vertical the pressure (heavy in section just need the 3rd road and more than).The shortcoming of this kind device is that the core of compacting has ovality, sometimes has corner angle, and surperficial roundness is poor, affects the electrical property of cable, has increased the possibility of cable breakdown.Another kind is the Compact Conical Die device, compare with the core that pressure roller is produced, the advantage of this kind method is that the core roundness of producing is good, do not require that the operator adjusts mould, it is not very high requiring for operator's technical ability, and most producer uses this kind device, but that shortcoming is the core aluminium bits produced is many, the aluminium bits gather and cause the bag that insulated, puncture when extrusion molding, affect the electrical property of cable.
The utility model content
The purpose of this utility model is to provide a kind of insulated cable manufacturing aluminium conductor compacting device, this compacting device has broken that traditional single press-roller device presses or single Compact Conical Die device presses circle, greatly reduced the generation of aluminium bits, the conductor thread core of producing is rounding but also only have a small amount of aluminium bits not only, does not affect the electrical property of cable.
To achieve these goals, the technical solution of the utility model is: a kind of insulated cable manufacturing aluminium conductor compacting device is provided, comprise wire parallel module, horizontal pressure roller, vertical pressure roller, Compact Conical Die and drip the silicone oil device, wire parallel module, horizontal pressure roller, vertical pressure roller and Compact Conical Die from left to right are located at outer aluminium monofilament outer surface successively, drip the silicone oil device and be located at above Compact Conical Die, drip a silicone oil device and be provided with woven hose.
Described Compact Conical Die is the nanocrystalline diamond composite coating drawing-die.
The utility model first adopts the twice pressure roller continuously on same twisted layer, adopt one afterwards Compact Conical Die, at the continuous drop silicone oil in Compact Conical Die die orifice place again.This device has broken that traditional single press-roller device presses or single Compact Conical Die device presses circle, and press-roller device and Compact Conical Die device are used in conjunction with effectively.First tentatively press through the twice pressure rollers, at this moment the core surface is not rounding very, then satisfies instructions for use through one Compact Conical Die drawing core rounding that just becomes.Because tentatively press through pressure roller, thus less through Compact Conical Die drawing deformation amount again, just do not have too many aluminium bits and produce.In order to reduce the aluminium bits as far as possible, at the continuous drop silicone oil in stranded conductor Compact Conical Die die orifice place, because silicone oil is tasteless nontoxic, can play certain lubrication and cooling effect to pressing drawing, greatly reduced the generation of aluminium bits, even there are a small amount of aluminium bits also can not affect extrusion molding, the conductor thread core of producing like this is rounding but also only have a small amount of aluminium bits not only, does not affect the electrical property of cable.Simultaneously silicone oil is stayed conductive surface and can be prevented the conductor oxidation and can prevent effectively that cable from axially intaking.Again due to silicone oil insulation, thereby improved insulating performance of cable.

In figure: 1. wire parallel module (wooden model), the 2. horizontal pressure roller of first, 3. vertical pressure roller, 4. Compact Conical Die, 5. unlined aluminium core, 6. outer aluminium monofilament, 7. droplet silicone oil device, 8. traction wheel of second.
Embodiment
In order to describe the manufacturing of the utility model insulated cable in detail with the technology contents of aluminium conductor compacting device, structural feature, below in conjunction with execution mode and coordinate accompanying drawing to be described further.
As shown in Figure 1, 2, 3, the utility model is at wire parallel module (wooden model) the 1 horizontal pressure roller 2 of rear continuous installation first and the vertical pressure roller 3 of second, it is the nanocrystalline diamond composite coating drawing-die that this mould of Compact Conical Die 4(is installed afterwards again), a silicone oil device 7 is installed at 4 places at Compact Conical Die.Under the traction of traction wheel 8, outer aluminium monofilament 6 is stranded on unlined aluminium core 5 after by wire parallel module (wooden model) 1, this stranded core becomes the large ellipse in little left and right, up and down after the horizontal pressure roller 2 of first presses, after pressing, the vertical pressure roller 3 of second becomes again circle (this moment be not very rounding), then through the Compact Conical Die 4 drawing conductors rounding that just becomes.Press main distortion and be placed on the horizontal pressure roller 2 of first and the vertical pressure roller 3 of second, strictly control the deflection of Compact Conical Die 4, if the deflection of Compact Conical Die 4 is too large, the aluminium bits can be many; If the deflection of Compact Conical Die 4 is too little, the roundness of conductor does not have due effect with regard to controlling bad.The silicone oil of packing in dripping silicone oil device 7, silicone oil drips to the Compact Conical Die porch continuously by woven hose, and it is lubricated with cooling.This device is applicable to the products such as low-voltage cable, 10kV crosslinked cable, suspended insulated guide wire, low pressure flame retardant cable or 10kV flame-proof cross-linking cable.
Above disclosed is only preferred embodiment of the present utility model, certainly can not limit with this interest field of the utility model, and the equivalent variations of therefore doing according to the utility model claim still belongs to the scope that the utility model is contained.
