Description
Technical field
The present invention relates to roller surface laser roughening processing treatment technology, refer to particularly a kind of roll disordered texturing processing method based on optical fiber laser.
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 the roll surface of cold roll, leveling roll to carry out texturing processing, then roll out the cold rolling textured steel sheet that meets the requirement of user's special process.
Up to the present, the development experience of roller texturing technology and equipment three phases: start shot-peening texturing, electric spark texturing and the nineties in 20th century research and development laser roughening.Shot Blasting noise is high, dust is large, power consumption is high, processing cost is high, and roller surface region 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, power consumption large, maintenance inconvenience and the problem such as oil pollution is serious.Laser roughening technology can obviously be improved texturing plate deep drawability and coating performance, and noiseless, pollution-free in texturing process.Along with the maturation in laser roughening market, increasing enterprise adopts this new technology of laser roughening.
Traditional laser roughening generally adopts CO
2with YAG laser instrument, 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
2with YAG laser instrument, optical fiber laser have photoelectric transformation efficiency high, better guarantee the advantages such as 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, may progressively replace global most of high power CO
2laser instrument and most YAG laser instrument.
The processing features of current most of laser texturing equipment is, in process, the laterally at the uniform velocity mobile uniform speed rotation who coordinates roll of laser Machining head (or bull), at roller surface, form the helical scanning line lattice texturing hole distribution (pitch is less, and texturing point distributes and can regard the parallel circumference texturing point distribution of a lot of bars as) at the inclination angles such as uniform pitch.The roll that texturing goes out is like this 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 reflections strong, finally causes there is different reflecting effects at different angle access panel faces, has affected the outward appearance of surface of steel plate.In addition, cold-rolled steel sheet easily forms and pulls at length direction, is because roll fits tightly at position and the steel plate of these straight lines, and the iron filings that produce can not be absorbed by the texturing of roller surface hole, all the time be present between steel plate and roll, mark continuously visible streak.
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 the even dot matrix of spirality as shown in Figure 2, although but this texturing hole distribution mode is all non-rectilinear rule in roll circumference direction and length direction, along screw thread inclination direction, be but orderly, when roll rolling strip, also can affect plate face at the reflecting effect of different angles.Chinese patent " a kind of processing method of multiple head laser disordered texturing roller surface " (publication number CN102699524A) proposes with random signal generator control impuls laser instrument, change frequency and the dutycycle of laser pulse bundle, make pattern and the distribution density of texturing point inconsistent to realize disordering, as shown in Figure 3, shortcoming is to cause obtaining the uniform cold-rolled steel sheet of roughness, also can impact steel plate deep drawability.In addition, Chinese patent " fiber laser texturing system " (publication number CN102380706A) is described rotates laser head and deflection motion also can make texturing point pattern irregular, and control appliance is more complicated.
Therefore, do not affecting under the condition of steel plate roughness uniformity and deep drawability, the key that realizes 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

Preferably, in described step 1), the rotary speed ω=10～30rpm of processed roll, transformation period t=5～10s.Like this, can produce the texturing dot matrix that meets template, deep drawing quality, percentage elongation, coating performance requirement at processed roller surface.
Preferably, described step 2) in, the transverse moving speed v=10～100mm/s of laser focusing head.Like this, can produce pattern and unified, the even unordered texturing dot matrix of size 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 μ m, and tranmitting frequency is 2000～3000Hz.Pulse laser beam within the scope of this can make texturing treatment effeciency higher.
Preferably, described step 2) in, laser focusing head is at the axis along processed roll from head end slides into end, and the mobile pitch of dislocation immediately, is oppositely back to head end; At head end, misplace again and move a pitch, continue to slide into end, until laser focusing head scans whole processed roller surface.In texturing processing procedure, 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: make the rotary speed randomly changing of processed roll, coupling simultaneously control laser head along processed roll mandrel to transverse moving speed, and regularly to roller surface Emission Lasers bundle, at processed roller surface, form texturing point; The staggered high density of short distance spirality that formed texturing point is variable-pitch and variable inclination angle is little micro-hole dot matrix evenly.The short distance helix that the inventive method processed in t in transformation period is arranged and is formed by 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 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, thereby form the staggered little micro-hole of short distance helix dot matrix.Use the texturing point that the inventive method processes to be uniformly distributed at processed roller surface, because the length of the short distance helix that processes in t transformation period is certain, make the spacing of texturing point on processed roll constant.Meanwhile, short distance helix is staggered and makes texturing hole all be the irregular distribution of nonlinear type in any direction of processed roll, can produce and really meet the processed roll that even disordering requires.
