Description

A kind of metallic conductor shaped device

Technical field

Metallic conductor forming field is the utility model is related to, more specifically, is related to a kind of metallic conductor shaped device.

Background technology

Process is the important procedure during cable is manufactured, can be with shape by the way that the concentric process of the single line of minor diameter is combined The stranded conductor small into soft, surface area, the deficiency that solid conductor rigidity is big, surface-discharge amount is big is improved well.

Generally use routine process in production, i.e., stranded conductor is stranding into using circular single line with one heart.Due to circular single line Between gap be present, the fill factor of the conductor that conventional process forms for 0.75 (in stranded conductor the sectional area summation of single line with The ratio of the external area of a circle of stranded conductor), also just say there is 25% void area in stranded conductor.In order to reduce stranded conductor External diameter, to reduce the dosage of conductor external cladding material, generally use press mode strand conductor synchronously carry out when twisted it is outer Compress in footpath.

All it is in special twisted wire using several or even tens of round wires when existing metallic conductor process presses shaping Carried out on machine.While round wire rotates with wire twisting machine, it is twisted under traction wheel effect by one or two aperture ratios The small fixation drawing mould of external diameter, its external diameter taper into defined size, length increase, produce plastic deformation.

In production, due to being sliding friction when metallic conductor monofilament passes through mould, coefficient of friction is big, caused by process Resistance of deformation is big, and production efficiency is very low, and energy resource consumption is high.Meanwhile the temperature in process mold work area when pressing is very high, particularly When process presses aluminium conductor or aluminium alloy conductor, aluminium powder caused by friction can be deposited in workspace, compressing mold at work because Conductor outside surfaces need to clean and can not add lubricant, form very hard alumina block at high temperature, destroy stranded conductor table Face quality, reduce die life, high material consumption.And in actual production, it is necessary to using a diameter than stranded conductor and The small metallic cable in drawing mould aperture is as guide line so that stranded conductor passes through mould.Due at the beginning of guide line and stranded conductor Beginning connection is only capable of being twisted several monofilament by hand, and guiding thread breakage often occurs when stranded conductor enters drawing mould, it is necessary to weight Again repeatedly could be by the way that production efficiency is low.

How to improve the surface quality for pressing metallic conductor in process process, while reduce because mould loss and failure are brought Cost, improve and press the productivity ratio of process, be the major issue for needing to solve instantly.
