Technical field
The utility model relates to the cold rolled strip steel production field, is specifically related to a kind of device of maintaining stable operation of strip steel for cold-rolled strip steel production unit.
Background technology
In cold rolled strip steel production unit band steel running, problems such as the design defect of local devices, structural damage or the system failure all can be brought out unit vibration in various degree.This unstability will make the band steel phenomenon of rocking and shaking occur; Some reason can make the band steel deviation phenomenon occur as low, the installation deviation of the accuracy of manufacture of rotation roller on belt plate shape and the equipment thereof.For guaranteeing the production efficiency and the product percent of pass of unit, need the stable operation of retainer belt steel.
In recent years, along with the fast development of China's energy construction, the high-effect transformer of energy savings had begun to use in power industry, and became development trend from now on.Orientation silicon steel mainly as the core material of transformer and other electrical equipment, requires its magnetic flux density height and iron loss low.At present, the technology that laser scored processing reduces iron loss being carried out on the orientation silicon steel surface reaches its maturity.On the laser scored unit of orientation silicon steel, the required precision of laser scanning spacing and width of nick is also very high, ends as the sound of laser scanning spacing that error requirements is controlled under the state ± 0.1mm, and the line of weakness degree of depth requires in 1～30 μ m.For this type of unit, shake and the sideslip of band steel in running all is unallowed.
Summary of the invention
Technical problem to be solved in the utility model is: provide a kind of device of maintaining stable operation of strip steel for cold-rolled strip steel production unit, so that solve the band steel that exists in the prior art rocking in running, shake and sideslip defective.
The technical scheme that its technical problem that solves the utility model adopts is: comprise uncoiler and coiling machine, they are contained in unit head, afterbody respectively, are provided with high-precision encoder on uncoiling, coiling machine.Set up idler roller in unit, this idler roller comprises contour left roller and right roller, and left roller absolute altitude is higher than the absolute altitude of entrance pinch roll, and right roller absolute altitude is higher than the absolute altitude that exports pinch roll, forms cornerite respectively at the entrance and exit of idler roller, makes the tensioning of band steel; The CPC device is installed at rear portion at uncoiler, and it is band steel automatic centering correction control device; Set up the EPC device before coiling machine, it is the automatic opposite side correction of band steel control device.
The utility model compared with prior art has following main advantage:
The stable operation of band steel when having guaranteed the work of cold-strip steel unit, the unit production efficiency that rock when eliminating because of the operation of band steel, shake and sideslip causes is not high, has improved unit productivity ratio, qualification rate.
In laser scored unit, the idler roller zone can be eliminated rocking of band steel fully and be shaken, and satisfies high stability, the high-precision requirement of laser scored unit to the band steel.

Among the figure: 1. uncoiler; 2.CPC device; 3. entrance guide plate; 4. entrance pinch roll; 5. idler roller; 6. outlet pinch roll; 7. centralising device; 8. cut and cut; 9. slewing rollers; 10. delivery guide; 11.EPC device; 12. coiling machine; 13. left roller; 14. right roller.
The specific embodiment
The device of the maintaining stable operation of strip steel for cold-rolled strip steel production unit that the utility model provides, its structure be as depicted in figs. 1 and 2: comprise uncoiler 1 and coiling machine 12, they are contained in unit head, afterbody respectively.On uncoiling, coiling machine, be provided with high-precision encoder; In unit, set up idler roller 5, this tension unit comprises contour left roller 13 and right roller 14, and left roller 13 absolute altitudes are higher than the absolute altitude of entrance pinch roll 4, and right roller 14 absolute altitudes are higher than the absolute altitude that exports pinch roll 6, entrance and exit at idler roller forms cornerite respectively, makes the tensioning of band steel.CPC device 2 is installed at rear portion at uncoiler 1, sets up EPC device 11 before the coiling machine, prevents strip running deviation.
Described CPC device 2 is that closed loop follows the tracks of regulating system, and this device can adopt German EMG company product.During production, CPC device 2 is measured the change in location at the strip center of advancing continuously, after detecting deviation, deviation signal is imported the strip controlled adjuster, and export to servo valve after handling, the hydraulic cylinder that servo valve drives uncoiler 1 moves uncoiler 1, gets back on the predetermined unit center line with the strip of adjusting sideslip, reaches the purpose of strip automatic centering.
Described EPC device 11 is that closed loop follows the tracks of regulating system, and this device can adopt the automatic opposite side correction of the band steel control device of German EMG company.During production, EPC device 11 is measured the change in location at the strip edge of advancing continuously, and with strip marginal position deviation signal input strip controlled adjuster, export to servo valve after the processing, servo valve drives the hydraulic cylinder that links to each other with coiling machine 12 and makes coiling machine 12 mobile tracking forward (FWD) positions, and strip is batched exactly.
Described high-precision encoder is for adopting the import encoder, and this encoder can adopt Ku Baile 5000 types.Utilize its feedback speed signal controlling uncoiler 1 and coiling machine 12 torques, and then unit is carried out tension force control.
The device of the maintaining stable operation of strip steel for cold-rolled strip steel production unit that the utility model provides, its course of work is:
Crossing process: the band steel by uncoiler 1 uncoiling, via entrance guide plate 3, to entrance pinch roll 4 (detection take the lead through after, top roll is depressed; The lower roll transmission), arrive idler roller 5 (detection take the lead through after), then through outlet pinch roll 6 (detection take the lead through after, top roll is depressed; The lower roll transmission), arrive centralising device 7, the mechanical centering of taking the lead (function left soon by the centralising device band); Be with at last that steel cuts 8 via cutting, slewing rollers 9, delivery guide 10 deliver to coiling machine 12, after coiling machine 12 clamps the band steel, and tension band steel (top roll that exports pinch roll 6 simultaneously lifts), wear band and finish.
Operate as normal: after wearing band and finishing, uncoiler 1 quickens, and the top roll of entrance pinch roll 4 lifts, and CPC device 2 and EPC device 11 are devoted oneself to work simultaneously, and unit begins raising speed to operating rate, and keeps constant speed (± 0.2/min) work.
The whipping stage: when oneself work of a winding steel moves to afterbody, the unit reduction of speed, the top roll of entrance pinch roll 4 is depressed, and the top roll of outlet pinch roll 6 is depressed.Unit moves (maintenance constant speed) with the whipping velocity-stabilization, finishes until coiling machine 12 and batches.
