Abstract
The invention relates to a method for producing the insulating wire core of a cable, comprising the following steps: directly placing banded wires in front of a wire inlet of a mould for an extruding and molding machine by using a wire placing frame equipment, pulling out a plurality of single wires meeting the requirements of structures of conductors at the same time, placing the single wires in the mould, and meanwhile, directly forming the plurality of single wires into a single insulating wire core of the cable without adopting pitch stranding by using the original traction of the extruding and molding machine as both the insulating extruding and molding traction and the conductor placing traction. Due to the adoption of the method for producing the insulating wire core of the cable, on the one hand, the flexible properties of the insulating wire core is ensured through a plurality of single wires, and on the other hand, the unit length of the single conductor is shortened because the pitch stranding is not used, the resistance of the conductors is reduced, the current-carrying capacity is enhanced, the work efficiency is improved and the production cost is lowered.
Description
Technical field
The present invention relates to a kind of production method of insulated wire cores, relate in particular to a kind of insulated wire cores production method of cable.
Background technology
Cable is used for electric energy transmitting or control signal.Cable is the abbreviation of the electric wire of broad sense.Cable is normally by the cable of several or the stranded similar rope that forms of several groups of leads (at least two every group), mutually insulated between every group of lead, and often be twisted into round a center, whole outside is surrounded by the cover layer of high-insulation.Cable has power cable, control cable, compensating cable, shielded type cable, high-temperature cable, computer cable, signal cable, coaxial cable, fire-resisting cable, shipboard cable or the like.They all are made up of stranded conductor, are used for connecting circuit, electrical equipment etc.
Though wires and cables industry is a supporting industry just, in occupation of the output value of Chinese electrician trade 1/4.Its product category is numerous, and range of application very extensively relates to industries such as electric power, building, communication, manufacturing, and is all closely related with each department of national economy.Electric wire also is called as national economy " artery " and " nerve "; Be transmission of electric energy, transmission information and make various motors, instrument, instrument; Realizing the indispensable basic equipment of electromagnetic energy conversion, is necessary base product in following electrification, the informationized society.
And core is an important component part of cable, and it is related to the electric conductivity that makes cable.Insulated wire is a kind of High Performance Insulation lead, and this lead has insulating barrier, and the centre is a heart yearn; Ground floor is to be flavous polyamine film, and its thickness is several microns, but can bear the high voltage pulse of 3kv; The second layer is the varnished of high-insulativity, and the 3rd layer is transparent glass layer, and the gross thickness of insulating barrier is merely 20-100 μ m; Its advantage is that dielectric strength is high, all can bear the safe voltage that exchanges 3000V between two-layer arbitrarily, and current density is big.For transmission current, wire stylet should be processed with the good copper of electric conductivity, aluminium.At the outer bread one deck rubber or the plastics of general lead, be because rubber, plastics are insulator, their protections are arranged, safer during use.Conductor wire core extrude or the lapped insulation layer after, become insulated wire cores.The cable of different electric pressures and specification, insulation thickness is different.
Usually move with the flexible cable insulated wire cores and be divided into two operations formation: at first conductor is restrainted strand, and then the extrusion molding that insulate.Such production process has increased the link of operation circulation, makes production cost high, inefficiency.
Thereby moving the occasion electrical equipment in addition all adopts the multiply bundle structure that tangles to guarantee its flexibility with cable.But this structure is the quality that guarantees not to extrude because of the loose influence insulation of conductor and the soft degree of cable in conductor strand system process with in the operation circulation; Taked to reduce the method for conductor pitch; Though this method is playing certain function aspect the total quality of flexibility that guarantees cable and cable, the while reduces because of pitch, causes the actual effective length of every monofilament on the unit length to increase; The resistance value of conductor is increased, and temperature rises during cable work.
Summary of the invention
To the deficiency of prior art, one of the object of the invention is to provide a kind of insulated wire cores production method of cable, thereby reduces process flow, enhances productivity, and reduces production costs.
The production method of insulated wire cores provided by the present invention comprises the steps: synnema is placed directly in extruder die incoming line front with pay off rack equipment; The multifilament that will meet the conductor structure requirement involves simultaneously and gets in the extruder die; Simultaneously with the original traction of plastic extruding machine not only as the insulation extrusion molding but also as the traction of conductor unwrapping wire, directly become the insulation single-core line by multifilament.
Pay off rack has a variety of.Can be divided into according to power transmission: active actinobacillus frame and passive pay off rack; Can be divided into according to the pattern mode: vertical pay off rack and horizontal pay off rack; Can be divided into according to the axle center mode: shaft type pay off rack and shaftless pay off rack are arranged.Pay off rack among the present invention can use any type of pay off rack for reaching the object of the invention; And vertical pay off rack is owing to have better matching property with extruder die; So the preferred vertical pay off rack of pay off rack among the present invention, can produce the insulated wire cores of function admirable.
As optimal technical scheme, insulated wire cores production method of the present invention without pitch bundle strand, directly becomes the insulation single-core line by multifilament.
Monofilament quantity described in the manufacturing approach of cable use insulated wire cores provided by the present invention is 5～9, preferred 7.In order to reduce production costs, in order to make the flexibility of the insulated wire cores that makes, the present invention has selected the monofilament of suitable radical on the other hand, comes to ensure better the insulated wire cores of utilizing the present invention to make on the one hand.
The production method of insulated wire cores provided by the present invention; Both guaranteed on the one hand the softness of insulated wire cores, and do not had unit length that pitch form shortened single conductor on the other hand, reduced conductor resistance, improved current capacity, improved operating efficiency, reduced production cost through many root architectures.Fig. 1 is that insulated wire cores provided by the present invention is produced sketch map.
