The unidirectional dead-beat of whole high-strength metal wire rod is drawn into silk device and has been immersed in cooling water before drawing metallic fiber material, by traction wheel, provide drawing power, drawing starts rear metal wire rod and passes through respectively cone pulley and the line ball wire-crossing wheel as first cone pulley group top minimum of end of incoming cables, then enter the embedded wire drawing axis hole of the embedded wire-drawing die that is positioned at first Wire drawing die box topmost, simultaneously two cooling baths in Wire drawing die box respectively by gully-hole and spray apertures to cooling cavity spraying cooling water, make the cooling water in cooling cavity produce disturbance, produce heat exchange with water body around, with this, carry out cooling embedded wire-drawing die, take away the heat that metal wire rod distortion produces, play cooling effect fast, avoid raising because cooling deficiency makes metal wire rod temperature, and cause its mechanical property degradating trend obvious because the bad meeting of heat radiation shortens metal wire rod strain-aging, be embodied in strength increase, torsion value declines, easily produce the aspects such as torsional flaw, be unfavorable for producing qualified finished product, through this embedded wire drawing axis hole, metal wire rod enters the cone pulley at second cone pulley group top of matching with first cone pulley group subsequently, metal wire rod is wound around 1～3 circle clockwise, then enter 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, then enter the next cone pulley in first cone pulley group, repeat same action, until this completes the drawing between cone pulley group.Metal wire rod enters the cone pulley group of a pair of cooperation again from the cone pulley of the diameter maximum of second cone pulley group bottom, this a pair of cone pulley group size shape equates cone pulley group with last, just placement direction is with last contrary to cone pulley group, be the cone pulley of diameter minimum in bottom and the cone pulley of diameter maximum at top, by last, cone pulley group metal wire rod is out entered and belongs to this cone pulley to the 3rd of cone pulley group the cone pulley group base diameter minimum, then enter the embedded wire drawing axis hole of the embedded wire-drawing die that is positioned at second Wire drawing die box foot, simultaneously two cooling baths in Wire drawing die box respectively by gully-hole and spray apertures to cooling cavity spraying cooling water, make the cooling water in cooling cavity produce disturbance, with this, carry out cooling embedded wire-drawing die, take away the heat that metal wire rod distortion produces, play cooling effect fast, enter subsequently the cone pulley of the 4th the cone pulley group bottom of matching with the 3rd cone pulley group, metal wire rod is wound around 1～3 circle counterclockwise, then enter the 3rd the next cone pulley in 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, then enter the upper cone pulley in the 3rd cone pulley group, repeat same action, the cone pulley of the diameter maximum by the 4th cone pulley group top after drawing completes enters the 3rd pair of cone pulley group.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, be the cone pulley of diameter maximum in bottom and the cone pulley of diameter minimum at top, the top drum wheel of the 5th cone pulley group is as the input of metal wire rod, the 3rd pair of cone pulley group and the 3rd Wire drawing die box being mated with first pair of mode drawing metallic fiber material that cone pulley group is identical with first Wire drawing die box, after drawing completes, metal wire rod from the cone pulley of the 6th cone pulley group bottom out, by three break-in wire-crossing wheels, be connected with traction wheel with a longitudinal wire-drawing die, and enter thus next process.Wherein, the cone pulley of the 6th cone pulley group bottom and traction wheel keep same linear velocity.
In whole drawing process, because the cone pulley diameter in first pair and the 3rd pair of cone pulley group increases from top to bottom gradually, so the linear velocity of the metal wire rod of arranging from top to bottom rotation is also increasing gradually, and cone pulley diameter in second pair of cone pulley group increases from top to bottom gradually, so the linear velocity of metal wire rod rotation from down to up is also increasing gradually, comparatively speaking, the rotating speed of cone pulley group will be higher than the rotating speed of cone pulley group above below, by accurate calculating, set the gradient of cone pulley in cone pulley group, the linear velocity of each cone pulley and the metal wire rod length of growth are agreed with mutually, not only accomplish drawing but also can not cause 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 the embedded wire drawing axis hole of back.Compared to traditional arrangement form, each has greatly reduced to the positive and negative staggered arrangement of cone pulley group the layout that is drawn into wire-crossing wheel quantity in silk device, greatly reduced the number of times of metal wire rod bending and torsion, cause consequent bending stress and centrifugal stress negligible, avoided the bending and torsion of small curvature radius, the flexural deformation possibility that has reduced metal wire rod, metal wire rod mechanical property and surface quality are reliable and stable.Simultaneously, because being, the central axis of embedded wire drawing axis hole is horizontally disposed with, and all cone pulley groups are in upright arrangement and arrange, between cone pulley group and Wire drawing die box, between cone pulley group for directly entering cabling, realized with directly entering drawing between diameter cone pulley, be between the cone pulley of the pulling capacity same diameter that is only present in same level height, metal wire rod oblique movement is cabling and there is no drawing process when the cone pulley of differentiated levels.Cone pulley working face is cylinder (without the conical surface), be convenient to processing, make cone pulley design accuracy be easy to ensure, in the present invention, cone pulley cylindricity is controlled in 0.015mm, and after assembling, cone pulley group cone pulley jitter values is controlled in 0.05mm, cone pulley surface adopts sprayed wc high abrasion resisting material, this material can guarantee that cone pulley case hardness is not less than 62HRC, and surface roughness is less than Ra0.4, makes the drawing of directly entering between same diameter cone pulley remain on low sliding mode.
The industrial solar energy cutting wire of often using of take is example, and solar energy cutting wire is senior TC steel wire (0.10mm～0.12mm), and it integrates the many merits such as stability, uniformity, high accuracy, high strength.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 to high requirement.In numerous metal wire rods, the performance requirement of solar energy cutting wire be that good straightness degree, flexibility are little, tolerance string diameter is little and even, 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 and 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 working face in the present invention is made as cylinder but not cone, can reduce the possibility that solar energy cutting wire overturns on cone pulley working face, thereby reduced the possibility of solar energy cutting wire torsional deflection, following table is contrasted the solar energy cutting wire that uses the present invention to produce and average mould consumption and the wire broken rate of the solar energy cutting wire that uses existing metal wire drawing device to produce respectively:
The average mould of drawing solar energy cutting wire consumes and surveys the wire broken rate situation table of comparisons by twisting method
| Hubbing method | Ton silk mould consumption (individual) | End breakage rate (inferior/km) |
| Existing metal wire drawing device | 37.6 | 1/92.1 |
| The present invention is drawn into silk device | 31.6 | 1/298.2 |
From mould consumption, use mould loss-rate existing apparatus of the present invention low; Compare end breakage rate, the about 90km of solar energy cutting wire that uses existing apparatus to produce just has a broken end, the about 300km of solar energy cutting wire that uses the present invention to produce just has a broken end, this explanation use the present invention contributes to improve plasticity and the toughness (showing in torsion and bending property) of solar energy cutting wire, has improved the combination property of solar energy cutting wire.
Means two: the central axis of embedded wire drawing axis hole is horizontally disposed, realization is with directly entering drawing between diameter cone pulley, simultaneously without wire-crossing wheel line falling, further reduced the flexion torsion of solar energy cutting wire, the solar energy cutting wire of producing not only ovality is all 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 is now oblique line drawing, solar energy cutting wire and Wire drawing die box are inclined to set, so just easily cause the solar energy cutting wire at embedded wire drawing axis hole two ends not on an axis, need to radially do minor adjustments along solar energy cutting wire, but because whole frame for movement has been done accurate setting, restriction is a lot, therefore regulate, be difficult to put in place, while causing solar energy cutting wire to move in Wire drawing die box, stretcher strain is not along solar energy cutting wire axis direction, to carry out completely, easy like this causing because of crackle fracture of wire.And the present invention adopts and directly enters drawing, because cone pulley working face is the non-cone of cylinder, and realized with directly entering drawing between diameter cone pulley, Wire drawing die box perpendicularity easily guarantees, torsion in steel wire drawing process is reduced, simultaneously owing to having cancelled the line falling process of minor diameter wire-crossing wheel, reduced the angle number of bends of solar energy cutting wire in three dimensions, reduce the factor that solar energy cutting wire nonhomogeneous deformation and residual stress increase, further reduced the bending of solar energy cutting wire and the probability of torsional deflection.Each embedded wire-drawing die by self-centering, easily maintains good coaxial state on Wire drawing die box, has reduced to greatest extent solar energy cutting wire because of the stress that nonhomogeneous deformation brings, and has realized high-precision drawing process, has reduced wire broken rate.
Means three: good cooling means is also to improve the requisite means of quality.
The bad direct harm bringing of cooling condition is to cause lubrication failure, thereby drawing stress is sharply increased, cause the inner residual stress that produces of solar energy cutting wire, and cause that solar energy cutting wire surface cracks, or because causing solar energy cutting wire surface, the destruction of lubricating layer turns white and cut, make solar energy cutting wire change inhomogeneous degree aggravation, easily cause fracture of wire.Meanwhile, local temperature is too high easily causes embedded wire drawing axis hole wearing and tearing uneven, affects die life and solar energy cutting wire quality.
Following table is recorded is the mechanical performance that adopts the solar energy cutting wire of several specifications that the present invention produces, and foregoing three kinds of means are summed up.
Detect 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 |
The solar energy cutting wire of more than showing diameter specifications and be 0.120mm is example, and this specification solar energy cutting wire that prior art is produced is done a comparison with this specification solar energy cutting wire that the present invention produces, and specifically sees the following form:
The flexible number of times of drawing solar energy cutting wire and can the number of torsions situation table of comparisons
| 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, 34 the just fractures of solar energy cutting wire bending that adopt the present invention to produce, and the solar energy cutting wire that existing apparatus is produced has just broken for crooked 30 times; Adopt the solar energy cutting wire torsion of existing apparatus production just to break for 35 times, and the solar energy cutting wire that the present invention produces torsion is just ruptured for 37 times, mechanical performance improves greatly.
As can be seen here, the present invention is simple in structure, the type of cooling is convenient in time, embedded wire-drawing die is stressed evenly, metal wire drawing process has overcome the additional stress that metal wire rod discontinuity produces effectively, effectively overcome the quality influence of additional residual stress to finished product metal wire rod, and applied widely, string diameter is that the drawing operation of 0.09mm metal wire rod also can be competent at.
In sum, the invention has the advantages that: between cone pulley group, realized the straight line traction drawing without directive wheel conversion, bending and the distortion of having avoided small curvature radius to cause, reduced metal wire rod bending and torsion number of times, reduced the internal flaw of high-strength metal wire rod, after drawing, metal wire rod thickness of coating is even, can stably keep certain circle footpath, seldom there is " 0 " line or " ingot " line, metal wire rod good straightness degree, mechanical property is even.
