Description
Technical field
The present invention relates to a kind of processing technology of electric wire, belong to controller switching equipment technical field.
Background technology
Electric wire refers to the conducting wire for transmitting electric energy.Divide bare wire, electromagnetic wire and insulated wire.Bare wire does not have insulating layer, including copper, aluminium
Horizontal line, overhead stranded conductor and various section bars (such as molded line, busbar, copper bar, aluminium row).It is mainly used for outdoor aerial and interior
Bus-bar and switch-box.Electromagnetic wire produces magnetic field or the insulated conductor for producing electric current is sensed in magnetic field after being switched on.It is main
For motor and transformer pitch of the laps and other in relation to electromagnetic equipment.Its conductor is mainly copper wire, should have thin insulating layer and
Good electricapparatus performance, and the performance such as heat-resisting, moisture-proof, solvent resistant.Different insulating materials is selected to obtain different
Characteristic.
In the prior art, the core of conductor wire makes usually using metal monofilament drawing, by filament through Drawing-anneal
Gather bunchy after being drawn to microfilament, formed through twisting sth. made by twisting；Metal monofilament drawing is typically only capable to be drawn to 0 .03mm string diameters, and continues
Drawing attenuates complex process, and production efficiency and yield rate are all very low, and cost increase.
Existing multiple core cord is formed due to twisting sth. made by twisting through more plying, and since string diameter is thicker, its ability resistant to bending is poor, small
When curvature such as radius of curvature bends for 1mm, multiple core cord can form plastic deformation and cannot spring back, therefore not folding is easily broken；It is existing
If multiple core cord monofilament, which fractures, may puncture insulating layer and leak electricity.
Domestic and international market is the most universal as the various high temperature electric wire cables of insulation using fluoroplastics, is exhausted especially using XETFE
The electric wire product of edge, sheath material, be widely used in aerospace field, but due to by XETFE materials in itself
Limitation, can only achieve 200 DEG C, it is impossible to meet work at higher temperature by insulation, the cable of sheath, its Long-term service temperature of the material
The requirement of environment.
The content of the invention

Belong to monofilament；
(iii) by metal monofilament degreasing degreasing；
(iv) by metal monofilament Cleaning and Passivation；
(v) it is metal monofilament is tin plating, i.e., the metal monofilament after Cleaning and Passivation is immediately placed in temperature in 25 DEG C~35 DEG C tin plating electrolytes
In, transmission speed control is controlled in 20~35a/dm in 6 ~ 8m/s, current density2；
(vi) process, is formed conducting wire by least two bursts of metal monofilament plying twistings, conducting wire is pressed using compacting machine；
(vii) obtained conducting wire is subjected to first time preheating, 80 DEG C is air-cooled to after being heated to 200 DEG C；
(viii) conducting wire is carried out second to preheat, is heated to 180 DEG C；
(ix) conducting wire is sent into extruder and carries out encapsulated, cladding insulating layer, obtained electric wire.
The improvement of above-mentioned technical proposal is：Step (i) in monofilament draw, under conditions of 58 DEG C, utilize wire drawing machine, warp
Overstretching mould, red copper bar is stretched, wire drawing it is a diameter of in 28um.
The improvement of above-mentioned technical proposal is：Step (ii) in 400 DEG C of annealing temperature, annealing time 15 minutes.
The improvement of above-mentioned technical proposal is：Step (v) in the metal monofilament after Cleaning and Passivation is immediately placed in temperature 25
In DEG C tin plating electrolyte, transmission speed control is controlled in 25a/dm in 7m/s, current density2。
