Description
Technical field
The present invention relates to a kind of method of utilizing wire-drawing frame drawing metal wire rod, more specifically relate to a kind of method of utilizing wire drawing machine to produce aluminum steel, aluminium alloy wire.
Background technology
Aluminium single line, aluminium alloy wire that the cable of China electric wire enterprise production is at present used generally adopt the multi-pass multiblock machine, and its equipment generally is made up of oil groove, drum, mould, take-up etc.Drawing process is consistent basically: with 9.5mm circle aluminium bar or aluminium alloy round bar as inlet wire, as requested go out the wire-drawing die that linear diameter prepares respective aperture, the quantity of mould also is to decide by going out linear diameter, requires the diameter of outlet more little, and the mould of outfit is many more.Wire rod is in the process of drawing, and under external force by force by tungsten carbide die, wire cross-section is long-pending to be compressed, and obtains desired shape and size.Wire rod tightly wraps in the end by means of take-up power and does not slide on a drum twining on the drum in the middle of each, drives aluminum steel or aluminium alloy wire drawing.There is recirculated water to cool off in the drum, circulating lubricating oil is housed in the oil groove mould and aluminum steel or aluminium alloy wire are lubricated cooling.
Above-mentioned drawing process is generally adopted, but comes with some shortcomings:
The first, a large amount of wire-drawing dies that adopt are tungsten carbide dies in the prior art, and tungsten carbide die exists temperature rise deformation big, and high temperature bed die aperture changes easily, can cause the aluminum steel or the aluminium alloy wire out-of-shape of pulling out; The high temperature bed die weares and teares easily, even cracking.Second, in the prior art, lubricating oil is by the oil pump supply that circulates from oil sump, this can produce two adverse factors: 1. one to two mould in drawing process front because aluminum steel or aluminium alloy wire temperature be low etc. reason can push down a lot of aluminium ends, lubrication oil circulation supply meeting is constantly taken these aluminium ends in other moulds, cause aluminum steel or aluminium alloy wire surface tear in the pulling process, though cut for the generation of medium drawing process, can be floating by next mould drawing, if but the aluminium end has been taken in last mould, will directly cause the blemish of finished product aluminum steel or aluminium alloy wire, aluminum steel or aluminium alloy wire that serious meeting causes drawing out are waste products, but frequent oil change more, the cost height, and must shut down and change, the meeting breaks in production; 2. circulate owing to lubricating oil, except lubricated, it also can have cooling effect to aluminum steel or aluminium alloy wire, the temperature of aluminum steel or aluminium alloy wire can not be raise, can not rely on the temperature on aluminum steel or aluminium alloy wire surface to evaporate by greasy dirt residual behind the mould, draw the aluminum steel or the aluminium alloy wire that come out and greasy dirt is arranged, surface blackening.Three, in the drawing process, the temperature of lubricating oil will be controlled at 70 ℃-72 ℃, and overheated and be out of shape to avoid tungsten carbide die, assurance can be played lubrication, and the adhesive force between aluminum steel or aluminium alloy wire and the lubricating oil is also little.The 4th, tungsten carbide die of the prior art exists temperature rise deformation big, can cause mould and wire rod frictional heat slow on the one hand, can not provide enough heats to heat up to lubricating oil, lubricating oil temperature rises to 70 ℃ by room temperature on the other hand needs 1 hour at least, in not meeting the requirements of during this period of time, temperature draws the aluminum steel or the aluminium alloy wire quality instability of coming out, percent defective is very high, aluminum steel or aluminium alloy wire can be squeezed out a lot of clouts and be deposited in the die hole surface simultaneously, not only scratch aluminum steel or aluminium alloy wire surface easily, and easy mold damage, pollution lubricating oil; Five, cause varying aperture for avoiding tungsten carbide die at high temperature to be out of shape, cause the aluminum steel or the aluminium alloy wire out-of-shape that draw, the drawing speed of aluminum steel or aluminium alloy wire drawing process is generally at 6 meter per seconds in the prior art, and production efficiency is low.For overcoming the deficiencies in the prior art, some manufacturing enterprises have also done some improvement on this basis, as publication number is that the Chinese patent application file of CN 101028633A discloses a kind of aluminum wiredrawing process, its technical scheme is: on above-mentioned technical matters basis, change last two to three wire-drawing dies into the glomerocryst mould, and reduce or close the circulation oil supply pipe of last two to three oil grooves, close or reduce cooling water in last two to three drums, by these steps, make circle aluminum steel or aluminium alloy wire surface generation high temperature when drawing, the greasy dirt that is bonded at round aluminum steel or aluminium alloy wire surface is fallen with high temperature evaporation.But still existing problems: what 1. the several moulds in front adopted is tungsten carbide die, lubricating oil in the oil groove is that circulation is supplied with, exist equally high temperature bed die varying aperture, aluminum steel or aluminium alloy wire extruding clout be deposited in the die hole surface, easily scratch aluminum steel or aluminium alloy wire surface, allow and speckle with problems such as greasy dirt even mold damage on aluminum steel or the aluminium alloy wire.2. close or reduce the circulation oil supply pipe of last two to three oil grooves, close or reduce cooling water in last two to three drums, last two to three wire-drawing dies change the glomerocryst mould into, because drawing speed reaches 12m/s, these steps make aluminum steel or aluminium alloy wire temperature too high, and do not have the measure of control corresponding temperature, and can produce oxide white at aluminum steel or aluminium alloy wire surface, reduce tensile strength, elongation rate of tensile failure and the conductance etc. of aluminum steel or aluminium alloy wire.
In common atmospheric environment, aluminium, aluminium alloy have good anti-corrosion, but when surperficial defectiveness, folding line, greasy dirt etc., strong corrosion center will be formed, particularly cable be when in use built on stilts on high in, stand throughout the year that rainwater charges and attacks and dew soaks, if aluminum steel or aluminium alloy wire surface defectiveness or be stained with greasy dirt, dust easily bonds, and moisture is difficult for evaporation, the oxidation that is corroded can occur, surface blackening, the broken string phenomenon appears in serious meeting, influences the service life of cable.
So, how to draw out the cleaning light, do not have the aluminum steel of cut or aluminium alloy wire to have crucial meaning.
Summary of the invention
