Abstract
The present invention relates to the drawing of metal wire rod and lubricate the particularly drawing die of aluminium clad steel wire and solid lubrication thereof.The present invention is directed to some defectives of prior art, a kind of drawing die and kollag pressure inlet with Rational structure, parameter proposed, and the reasonable coordinated scheme of pressure inlet internal diameter and die entrance place equal diameters, also having proposed a kind of pressed powder that adds 3～15% graphite powders or molybdenum bisuphide with dry calcium stearate simultaneously is lubricant, having reduced accidents such as the fusing in the drawing process, scaling loss and heap mould takes place, avoid the mould damage, improved yield rate and production efficiency.
Description
The stretching die and the solid lubrication thereof that the present invention relates to draw the stretching die of dialling metal wire rod and draw the lubricated field, particularly aluminium clad steel wire of dialling material.
At present, by the aluminium clad steel wire that methods such as continuous casting, extruding, stretching coating are produced, because dimensions is bigger, rough surface can't satisfy the use of departments such as electric power and communication, need reprocess, and promptly adopts the method that stretches that its diameter section is diminished.The stretching of aluminium Baogang core recombination line is different from ordinary lines and stretches, because clad material intensity is low, as drawing die unreasonable structure, the bad words of lubricating condition, in the drawing die deformed area, will produce very big frictional force, make the recombination line surface very easily produce fusing and scaling loss, also easily produce the heap mould in the mould, cause the recombination line yield rate to reduce, or at the drawing process interrupt line, and even destroy mould.Therefore, the process of dialling of drawing of aluminium clad steel wire not only needs the mould of Rational structure, also needs fabulous lubricating condition.Prior art all improves to some extent aspect two at this, except improving mould structure, also adopted the forced feed lubrication method, comprise liquid with two kinds of solid, as Japan's flat 1 open peace 1 openly, and the relative liquid of solid forced feed lubrication has clear superiorities such as investing little, simple, the easy operation of technology, so by social extensive the employing.However, existing these adopt aluminium clad steel wires of solid forced feed lubrications to stretch still, and mould structure, parameter reasonable inadequately for ubiquity, the kollag pressure inlet cooperates unreasonable with mould, defectives such as lubricant properties instability openly put down 1 as Japan Patent, cause at aluminium clad steel wire to draw fusing in the process of dialling, scaling loss and heap mould accident to take place again and again, the mould well damage, cause decrease in yield, production efficiency descends, and production cost rises.
Purpose of the present invention is intended to make improvements according to problems of the prior art, to obtain a kind of structure, Rational Parameters, be specially adapted to aluminium clad steel wire and draw the drawing die of dialling, a kind of kollag of better performances and pressure inlet thereof, and the reasonable coordinated scheme of pressure inlet and mould draw the generation of the accidents such as fusing, scaling loss and heap mould in the process of dialling with minimizing, avoid mold damage, improve yield rate, enhance productivity, reduce production costs.
For achieving the above object, the present invention proposes a kind of drawing die and kollag pressure inlet, reach their reasonable coordinated scheme, also proposed a kind of kollag of better performances simultaneously with Rational structure, parameter.
Figure 1 shows that drawing die structural representation of the present invention
Use schematic diagram after Figure 2 shows that mould assembling pressure inlet of the present invention
As shown in Figure 1, mould of the present invention comprises Drawing cone (2), calibrating strap (3) and goes out prostomum (4).Angle, garden, Drawing cone porch (1) radius of curvature R=0.5～2.0mm, the calibrating strap diameter D of long L=1～4 of Drawing cone (2) times, modular angle α=4～25 of Drawing cone (2) °, the long l=1.0～2.5mm of calibrating strap (3).
As shown in Figure 2, be arranged on drawing die (6) the inlet the place ahead and the long L '=50～60mm of the kollag pressure inlet (5) of coaxial connection with it, its inner diameter d=aluminium clad steel wire blank diameter+0.25～0.5mm that waits to stretch, and with the die entrance equal diameters.
The kollag that the present invention proposes is by weight percentage: graphite powder or molybdenum bisuphide 3～15%, all the other are dry carbon resin acid calcium.
The present invention has confirmed the structure of drawing die and pressure inlet by a large amount of tests, the reasonability of parameter, pressure inlet internal diameter and can significantly reduce the chance that the heap mould takes place cooperating of die entrance place equal diameters wherein, adopt calcium stearate interpolation suitable amount of graphite powder or molybdenum bisuphide to do the solid lubrication powder simultaneously, the lubricated optimum efficiency of aluminium clad steel wire can obtain to stretch, the generation of fusing, scaling loss and heap mould accident be can significantly reduce, yield rate and production efficiency improved.
With C content be wrap fine aluminium around 0.70% the φ 5.5mm steel core wire after, the external diameter of aluminium clad steel wire is φ 6.4mm.Adopt drawing die of the present invention and pressure inlet device, stretch with the pressed powder lubricant of calcium stearate+5% graphite powder or molybdenum bisuphide, be stretched to φ 3.0mm through 7 passages, aluminium coating is 0.12mm, and its mechanical performance is σ
b=1350N/cm
2, δ %=5%, turning round and twisting with the fingers number of times is that 25 secondary aluminiums and steel core are not stratified, the no any scar in recombination line surface draws the process of dialling not have the broken string accident.
Claims (3)
1, a kind of drawing die of aluminium clad steel wire and lubricated, comprise and be arranged on the drawing die inlet the place ahead and the kollag pressure inlet of coaxial connection with it, it is characterized in that: the long L=1.0～2.5mm of the calibrating strap of stretching die (3), modular angle α=the 4-25 of Drawing cone (2) °, calibrating strap (3) the diameter D of long L=1～4 of Drawing cone (2) times, angle, Drawing cone (2) garden, porch (1) radius of curvature R=0.5～2.0mm; Long L=50～the 60mm of pressure inlet (5), its inner diameter d=aluminum-clad steel wire blank diameter+0.25～0.5mm waits to stretch.
2, stretching die according to claim 1 and lubricated, it is characterized in that: the internal diameter of wherein said pressure inlet (5) equates with the drawing die inlet diameter.
3, a kind of drawing die of aluminium clad steel wire and lubricated, it is characterized in that: kollag is by weight percentage: graphite powder or molybdenum bisuphide 3～15%, all the other are dry calcium stearate.
