nullBefore drawing metallic fiber material the unidirectional dead-beat of whole high-strength metal wire rod be drawn into silk device be immersed in cooling water in，Drawing power is provided by traction wheel，Drawing starts rear metal wire rod respectively through the minimum cone pulley in first cone pulley group top as end of incoming cables and line ball wire-crossing wheel，Embedded wire drawing axis hole subsequently into the embedded wire-drawing die being positioned at first Wire drawing die box topmost，Simultaneously two cooling baths in Wire drawing die box respectively through gully-hole and spray apertures to cooling cavity spraying cooling water，The cooling water in cooling cavity is made to produce disturbance，Heat exchange is produced with the water body of surrounding，Embedded wire-drawing die is cooled down with this，Take away the heat that metal wire rod deformation produces，Play the effect of quickly cooling，Avoid making metal wire rod temperature raise because cooling down deficiency，And cause that its mechanical property degradating trend is obvious owing to bad meeting of dispelling the heat makes metal wire rod strain-aging shorten，It is embodied in intensity to increase、Torsion value declines、It is easily generated the aspects such as torsional flaw，It is unfavorable for producing qualified finished product；Through this embedded wire drawing axis hole, metal wire rod enters the cone pulley at second the cone pulley group top matched with first cone pulley group subsequently, metal wire rod wound clockwise 1～3 encloses, subsequently into the next cone pulley in first cone pulley group, after this cone pulley is wound around, metal wire rod is through the embedded wire drawing axis hole of the embedded wire-drawing die of the next one of first Wire drawing die box, and enter the next cone pulley in second cone pulley group, metal wire rod is wound around 1～3 circle on this cone pulley, subsequently into the next cone pulley in first cone pulley group, repeat same action, until the drawing between cone pulley group is completed by this.nullMetal wire rod enter from the maximum cone pulley of the diameter bottom second cone pulley group again the cone pulley group of a pair cooperation，This pair cone pulley group size shape is equal to cone pulley group with previous，Simply placement direction is contrary to cone pulley group with previous，Namely the cone pulley cone pulley that diameter is maximum in bottom that diameter is minimum is at top，This is belonged to the minimum cone pulley of the 3rd cone pulley group base diameter of cone pulley group by previous cone pulley group metal wire rod out entered，Embedded wire drawing axis hole subsequently into the embedded wire-drawing die being positioned at second Wire drawing die box foot，Simultaneously two cooling baths in Wire drawing die box respectively through gully-hole and spray apertures to cooling cavity spraying cooling water，The cooling water in cooling cavity is made to produce disturbance，Embedded wire-drawing die is cooled down with this，Take away the heat that metal wire rod deformation produces，Play the effect of quickly cooling，Subsequently enter the cone pulley bottom the 4th the cone pulley group matched with the 3rd cone pulley group，Metal wire rod wrapped anti-clockwise 1～3 encloses，Subsequently into the next cone pulley in the 3rd cone pulley group，After this cone pulley is wound around, metal wire rod is through the embedded wire drawing axis hole of a upper embedded wire-drawing die of second Wire drawing die box，And enter the upper cone pulley in the 4th cone pulley group，Metal wire rod is wound around 1～3 circle on this cone pulley，Subsequently into the upper cone pulley in the 3rd cone pulley group，Repeat same action，Drawing enters the 3rd pair of cone pulley group by the cone pulley that the diameter at the 4th cone pulley group top is maximum after completing.And the arranged direction of the 3rd pair of cone pulley group is identical with first pair of cone pulley group, second pair of cone pulley group is contrary, namely the cone pulley cone pulley that diameter is minimum in bottom that diameter is maximum is at top, the top drum wheel of the 5th cone pulley group is as the input of metal wire rod, 3rd pair of cone pulley group and the 3rd Wire drawing die box being mated drawing metallic fiber material in the way of identical with first pair of cone pulley group and first Wire drawing die box, drawing complete after metal wire rod from the cone pulley bottom the 6th cone pulley group out, it is connected with traction wheel by three break-in wire-crossing wheels and a longitudinal wire-drawing die, and hence into next process.Wherein, the linear velocity that the cone pulley bottom the 6th cone pulley group and traction wheel maintain like.
In whole drawing process, owing to the cone pulley diameter on first pair and the 3rd pair of cone pulley group is gradually increased from top to bottom, so the linear velocity that the metal wire rod arranged from top to bottom rotates also is being gradually increased, and the cone pulley diameter in second pair of cone pulley group is gradually increased from top to bottom, so the linear velocity that metal wire rod from down to up rotates also is being gradually increased, comparatively speaking, the rotating speed of cone pulley group is higher than the rotating speed of above cone pulley group below, the gradient of cone pulley in cone pulley group is set by calculating accurately, the linear velocity of each cone pulley is agreed with mutually with the metal wire rod length of growth, not only accomplish drawing but also be not result in metal wire rod differential deformation and produce residual stress.Meanwhile, because metal wire rod is to draw thinner and thinner, after the aperture of embedded wire drawing axis hole of a step be less than the aperture of embedded wire drawing axis hole of back.Compared to traditional arrangement form, the each pair of positive and negative staggered arrangement of cone pulley group greatly reduces the layout being drawn in silk device wire-crossing wheel quantity, greatly reduce metal wire rod bending and the number of times reversed, cause that consequent bending stress and centrifugal stress are negligible, avoid bending and the torsion of little radius of curvature, reducing the flexural deformation probability of metal wire rod, metal wire rod mechanical property and surface quality are reliable and stable.Simultaneously, owing to the central axis of embedded wire drawing axis hole is in being horizontally disposed with, and all cone pulley groups arranges in array, it is straight cabling between cone pulley group and Wire drawing die box, between cone pulley group, achieve the straight drawing between same diameter cone pulley, namely pulling capacity exists only between the cone pulley of same diameter of same level height, and metal wire rod oblique movement is cabling when the cone pulley of differentiated levels and there is no drawing process.Cone pulley work surface is cylinder (without the conical surface), it is easy to processing, cone pulley design accuracy is made to be prone to ensure, in the present invention, cone pulley cylindricity controls within 0.015mm, and after assembling, cone pulley group cone pulley jitter values controls within 0.05mm, cone pulley surface adopts sprayed wc high abrasion resisting material, this material ensure that cone pulley case hardness is not less than 62HRC, and surface roughness, less than Ra0.4, makes the straight drawing between same diameter cone pulley be maintained at low sliding mode.
For the industrial solar energy cutting wire often used, solar energy cutting wire is senior TC steel wire (0.10mm～0.12mm), it integrate stability, uniformity, in high precision, the many merits such as high intensity.The production technology of solar energy cutting wire is that requirement is the most harsh in the production of metal wire rod, and production equipment and technology controlling and process are had high requirement.In numerous metal wire rods, the performance requirement of solar energy cutting wire is good straightness degree, flexibility is little, tolerance string diameter is little and uniform, warpage is little and diameter and ovality tolerance little.
By following detection means, the solar energy cutting wire of the solar energy cutting wire of existing apparatus drawing Yu drawing of the present invention is contrasted:
Means one, in being drawn into silk device, cone pulley gradient and machine coefficient are determined by least part compression ratio and low slide coefficient, in view of this, cone pulley work surface in the present invention is set to cylinder but not cone, the probability that solar energy cutting wire overturns on cone pulley work surface can be reduced, thus reducing the probability of solar energy cutting wire torsional deflection, the average mould consumption of the solar energy cutting wire that the solar energy cutting wire using the present invention to produce is produced by following table with the existing metal wire drawing device of use and wire broken rate are contrasted respectively:
The average mould of drawing solar energy cutting wire consumes and surveys wire broken rate situation synopsis by twisting method
| Hubbing method | Ton silk mould consumption (individual) | End breakage rate (secondary/km) |
| Existing metal wire drawing device | 37.6 | 1/92.1 |
| The present invention is drawn into silk device | 31.6 | 1/298.2 |
Consuming from mould, the mould loss-rate existing apparatus using the present invention is low；Relatively end breakage rate, use the solar energy cutting wire that existing apparatus produces to be about 90km and just have a broken end, use the solar energy cutting wire that the present invention produces to be about 300km and just have a broken end, this illustrates the plasticity and the toughness (showing in torsion and bending property) that use the present invention to be favorably improved solar energy cutting wire, improves the combination property of solar energy cutting wire.
Means two: the central axis of embedded wire drawing axis hole is horizontally disposed, realize with the straight drawing between diameter cone pulley, simultaneously without wire-crossing wheel line falling, further reduce the flexion torsion of solar energy cutting wire, the solar energy cutting wire not only ovality produced is respectively less than 0.002mm, and steady quality, quality poker is good.
In existing apparatus during drawing solar energy cutting wire, Wire drawing die box is installed might not have good perpendicularity (centering) with silk thread, it it is now oblique line drawing, solar energy cutting wire and Wire drawing die box are inclined to set, thus easily cause the solar energy cutting wire at embedded wire drawing axis hole two ends not on an axis, need radially to do minor adjustments along solar energy cutting wire, but because whole frame for movement has done accurate setting, restriction is a lot, therefore regulate and be difficult to put in place, when causing solar energy cutting wire to move in Wire drawing die box, stretcher strain is not carry out completely along solar energy cutting wire axis direction, so it is easily caused because of crackle fracture of wire.And the present invention adopts straight drawing, owing to cone pulley work surface is cylinder not rounded cone, and achieve the straight drawing between same diameter cone pulley, Wire drawing die box perpendicularity is easily guaranteed that, the torsion in steel wire drawing process is made to reduce, simultaneously because eliminate the line falling process of minor diameter wire-crossing wheel, decrease solar energy cutting wire angular number of bends in three dimensions, reduce solar energy cutting wire nonhomogeneous deformation and the factor of residual stress increase, reduce further the probability of the bending of solar energy cutting wire and torsional deflection.Each embedded wire-drawing die on Wire drawing die box by self-centering, it is easy to maintain good coaxial state, decrease the stress that solar energy cutting wire brings because of nonhomogeneous deformation to greatest extent, it is achieved that high-precision drawing process, decrease wire broken rate.
Means three: good cooling means, are also improve the requisite means of quality.
The bad directly harm brought of cooling condition is to cause lubrication failure, so that drawing stress sharply increases, cause solar energy cutting wire internal generation residual stress, and cause solar energy cutting wire surface to crack, or owing to the destruction of lubricating layer causes solar energy cutting wire surface to turn white and cut, make the degree aggravation that the change of solar energy cutting wire is uneven, it is easy to cause fracture of wire.Meanwhile, local temperature is too high is easily caused embedded wire drawing axis hole abrasion inequality, affects die life and solar energy cutting wire quality.
What following table was recorded is the mechanical performance of the solar energy cutting wire of several specifications adopting the present invention to produce, and foregoing three kinds of means have been summed up.
Detection table
| Diameter (mm) | Ovality (mm) | Fracture Force (N) | Tensile strength (MPa) | Lopping performance |
| 0.100 | <0.002 | >30 | 3800 | Good |
| 0.110 | <0.002 | >34 | 3550 | Good |
| 0.120 | <0.002 | >40 | 3500 | Good |
| 0.130 | <0.002 | >45 | 3450 | Good |
| 0.140 | <0.002 | >53 | 3400 | Good |
Above table diameter specifications is the solar energy cutting wire of 0.120mm is example, this specification solar energy cutting wire that this specification solar energy cutting wire that prior art produces is produced with the present invention is done one and compares, be specifically shown in following table:
The flexible number of times of drawing solar energy cutting wire and can number of torsions situation synopsis
| Hubbing method | Flexible number of times | Can number of torsions |
| Existing metal wire drawing device | 30 | 35 |
| The present invention is drawn into silk device | 34 | 37 |
As seen from the above table, adopt 34 just fractures of solar energy cutting wire bending that the present invention produces, and the solar energy cutting wire that existing apparatus produces bends 30 times and just breaks；Adopting the solar energy cutting wire that existing apparatus produces to reverse 35 times just to break, and the solar energy cutting wire that the present invention produces reverses 37 just fractures, mechanical performance is greatly improved.
As can be seen here, present configuration is simple, the type of cooling facilitates in time, embedded wire-drawing die uniform force, metal wire drawing process effectively overcomes the additional stress that metal wire rod discontinuity produces, effectively overcome the additional residual stress quality on finished metal wire rod to affect, and applied widely, the drawing operation that string diameter is 0.09mm metal wire rod also can be competent at.
In sum, it is an advantage of the current invention that: between cone pulley group, achieve the straight line traction drawing without directive wheel conversion, avoid bending and distortion that little radius of curvature causes, reducing metal wire rod bending and number of torsions, decrease the internal flaw of high-strength metal wire rod, after drawing, metal wire rod thickness of coating is uniform, can stably keep certain circle footpath, " 0 " line or " ingot " line seldom occur, metal wire rod good straightness degree, mechanical property is uniform.
