Description
Technical field
The present invention relates to roller surface laser roughening processing treatment technology, refer to a kind of roll disordered texturing processing method based on optical fiber laser particularly.
Background technology
The surface topography of cold rolled sheet steel has material impact to template, deep drawing quality, percentage elongation and coating performance, and the surface topography of cold rolled sheet steel depends on the surface topography of working roll and leveling roll in cold-rolling process to a great extent.Therefore, in flat cold-rolled sheet production technology, require to carry out frosting treatment to the roll surface of cold roll, leveling roll, then roll out the cold rolling textured steel sheet meeting the requirement of user's special process.
Up to the present, the development experience three phases of roller texturing technology and equipment: shot-peening texturing, electric spark texturing and the nineties in 20th century to start the laser roughening researched and developed.Shot Blasting noise is high, dust is large, power consumption is high, processing cost is high, and roller surface zone hardness, shot-peening size and impact speed and the angle of shock have randomness, inhomogeneities, are difficult to control and the shortcoming such as repeatability is bad.OnElectrical Discharge Texturing pattern uniformity, retentivity are better than shot-peening texturing, but have that roll working life is short, maintenance of equipment rate is high, the problem such as power consumption is large, maintenance is inconvenient and oil pollution is serious.Laser roughening technology obviously can improve texturing plate deep drawability and coating performance, and noiseless in texturing process, pollution-free.Along with the maturation in laser roughening market, increasing enterprise adopts this new technology of laser roughening.
Traditional laser roughening generally adopts CO
2and YAG laser, there is all deficiencies.The conversion efficiency of YAG laser texturing equipment pump light is low, crystal thermal effect serious, flash lamp needs often to change; Stabilization of equipment performance is poor, can not adapt to the requirement of large-scale production.CO
2laser texturing equipment is bulky, and automatic station-keeping system is complicated, and price is also very expensive, higher to the required precision of lathe; Gas consumption is large, and the chopper disk of texturing equipment needs often to change.Compare CO
2and YAG laser, optical fiber laser has the advantages such as photoelectric transformation efficiency high, better guarantee little micro-hole diameter and high texturing speed, maintenance cost be low.Optical-fiber laser, as the representative of third generation laser technology, has the unrivaled technological merit of other laser technologies and wide application development space, progressively may replace global most of high power CO
2laser instrument and most YAG laser.
The processing features of current most of laser texturing equipment is, in process, the laterally at the uniform velocity mobile uniform speed rotation coordinating roll of laser Machining head (or bull), the helical scanning line lattice texturing hole distribution (pitch is less, and the distribution of texturing point can regard the parallel circumference texturing point distribution of a lot of bar as) of uniform pitch isoclinic angle is formed at roller surface.The roll that such texturing goes out is orderly in a circumferential direction, and the size of its texturing point, pattern, arrangement are basically identical, as shown in Figure 1.When roll rolling strip, by transfer printing, there is equally distributed straight line in plate face along its length.Therefore, plate, under the irradiation of light, has several angle reflection strong, finally causes there is different reflecting effects in different angle views plate faces, have impact on the outward appearance of surface of steel plate.In addition, cold-rolled steel sheet is easily formed at length direction and pulls, and is because roll fits tightly at the position of these straight lines and steel plate, and the iron filings of generation can not be absorbed by the texturing of roller surface hole, all the time be present between steel plate and roll, mark visible streak continuously.
In order to solve the orderly texturing problem of laser texturing equipment, Chinese patent " a kind of laser texturing processing method on surface of roller " (publication number: CN101642778A) propose to accelerate laser roughening head along roll mandrel to movement rate, increase helix angle, form spirality uniform array as shown in Figure 2, although but this texturing hole distribution mode is all non-rectilinear rule in roll circumference direction and length direction, threadingly inclination direction is but orderly, when roll rolling strip, the reflecting effect of plate face in different angles also can be affected.Chinese patent " a kind of processing method of multiple head laser disordered texturing roller surface " (publication number CN102699524A) proposition random signal generator control impuls laser instrument, change frequency and the dutycycle of laser pulse bundle, make the pattern of texturing point and distribution density inconsistent to realize disordering, as shown in Figure 3, shortcoming causes obtaining the uniform cold-rolled steel sheet of roughness, also can impact steel plate deep drawability.In addition, described in Chinese patent " fiber laser texturing system " (publication number CN102380706A) laser head is rotated and deflection motion also can make texturing point pattern irregular, and control appliance is more complicated.
Therefore, under the condition not affecting steel plate roughness uniformity and deep drawability, the key realizing roll disordered texturing is to change traditional regular helix shape scan line distribution, and does not change pattern and the size of texturing point.
Summary of the invention
Object of the present invention is exactly to provide a kind of roll disordered texturing processing method based on optical fiber laser, and the roll adopting the method to deal can improve the appearance quality in plate face greatly, and can improve the wearability of roll, increases the service life.
For achieving the above object, the roll disordered texturing processing method based on optical fiber laser designed by the present invention, comprises the steps:
1) drive processed roll to rotate around its axial line, and make its rotary speed ω by the cycle t change at random of setting;
2) laser focusing head is aimed at processed roller surface, and it is traversing that its axis along processed roll is come and gone;

2=(π ω/60td)
2+ (vt)
2; Wherein, the unit of short distance helix δ and diameter d is mm, and the unit of transverse moving speed v is the unit of mm/s, rotary speed ω is rpm, and transformation period, the unit of t was s.According to short distance helix δ, transverse moving speed v, rotary speed ω, rotary speed ω transformation period t and processed roll diameter d between mathematical relationship accurately can calculate the length of short distance helix δ.
Preferably, in described step 1), the rotary speed ω=10 ~ 30rpm of processed roll, transformation period t=5 ~ 10s.Like this, can produce at processed roller surface the texturing dot matrix meeting template, deep drawing quality, percentage elongation, coating performance requirement.
Preferably, described step 2) in, the transverse moving speed v=10 ~ 100mm/s of laser focusing head.Like this, pattern and unified, the evenly unordered texturing dot matrix of size can be produced at processed roller surface.
Preferably, in described step 4), the wavelength of optical fiber laser institute emission pulse laser bundle is 1.46 ~ 1.61 μm, and tranmitting frequency is 2000 ~ 3000Hz.Pulse laser beam within the scope of this can make frosting treatment efficiency higher.
Preferably, described step 2) in, laser focusing head is after sliding into end along the axis of processed roll from head end, and the mobile pitch of dislocation immediately, is oppositely back to head end; Misplace again at head end and move a pitch, continue to slide into end, until laser focusing head scans whole processed roller surface.In frosting treatment process, make the distance that texturing platform movement is small, make disordering texturing dot matrix be covered with whole processed roll.
Operation principle of the present invention is: the rotary speed of processed roll is changed at random, coupling simultaneously control laser head along processed roll mandrel to transverse moving speed, and timing forms texturing point to roller surface Emission Lasers bundle at processed roller surface; The texturing point formed is the staggered high density of short distance spirality even little micro-hole dot matrix at variable-pitch and variable inclination angle.The short distance helix that the inventive method processed in t in transformation period is formed by the arrangement of texturing point.In pulse laser frequency one timing of optical fiber laser, the density of texturing point on processed roll changes with the length variations of short distance helix, and short distance helix is longer, and the density of texturing point on processed roll is lower; Otherwise short distance helix is shorter, the density of texturing point on processed roll is then higher.Due to the rotary speed of processed roll and laser head along processed roll mandrel to transverse moving speed change, the pitch of short distance helix and inclination angle also can change thereupon, thus form short distance helix staggered little micro-hole dot matrix.The texturing point using the inventive method to process is uniformly distributed at processed roller surface, because the length of the short distance helix processed in t transformation period is certain, makes the spacing of texturing point on processed roll constant.Meanwhile, short distance helix is staggered and makes texturing hole be all the irregular distribution of nonlinear type in any direction of processed roll, can produce the processed roll really meeting even disordering and require.
The invention has the advantages that: adopt the processed roll of disordered texturing method process, its texturing point is the little micro-hole of regular circle shapes, and texturing dot density is evenly distributed, and processed roll each position roughness is consistent; Form the staggered short distance helix be made up of high density dot matrix after processed roll process, substantially increase wearability and the service life of processed roll; Pitch and the inclination angle of short distance helix are unequal, and therefore texturing is cheated on roll footage direction and is all circumferentially the irregular distribution of nonlinear type, avoids the cold-reduced sheet brought thus and pulls problem; When using the roll rolled plate after the inventive method process, plate face texture structure lack of alignment, improves appearance quality and the service life of steel plate.
