Working principle: in this embodiment, the application also provides a method for using the intelligent steel strip rolling device for preventing stress deformation, which comprises the following steps:
firstly, an unreeling machine 2, a reeling machine 3, a servo motor, a driving motor, an oil pump 17 and a speed reducing motor 18 are respectively and electrically connected with external control equipment through wires, then oil is poured into an oil storage cavity of a lifting plate 12 through an oil injection valve pipe, the lifting plate 12 at the moment does not drive a tensioning roller 14 arranged on a mounting frame 13 to descend, then an adjusting assembly is started to adjust the height of an upper roller 5 in a lifting manner so as to adjust the rolling interval between the upper roller 5 and a lower roller 4, and then the driving motor at the rear end of the fixing frame is started to drive the lower roller 4 to rotate;
secondly, one end of the steel strip installed on the unreeling machine 2 passes through between the two groups of lower rollers 4 and the upper rollers 5, the steel strip to be rolled passes through the bottoms of the tensioning rollers 14, meanwhile, the primarily rolled steel strip is fixed on the reeling machine 3 for reeling, in the process of rolling the steel strip, in order to prevent the deformation of the steel strip due to stress, the lifting plate 12 is regulated in a descending manner by starting the driving assembly, the tensioning rollers 14 on the mounting frame 13 can be driven to tension the steel strip between the two groups of lower rollers 4 and the upper rollers 5 through the descending of the lifting plate 12, the condition that the steel strip is loosened after being rolled by one group of lower rollers 4 and the upper rollers 5 is avoided, and the deformation of the steel strip due to the stress generated in the primary rolling process can be avoided; the stress state of the stand can be changed, and the structural stability of the stand when the steel strip is rolled is improved;
step three, when rolling the steel strip, the spraying mechanism is started, so that double-sided oiling coating operation is conveniently carried out on the steel strip to be rolled before rolling; the rolling pressure can be reduced by about 10% -20% conveniently after the steel strip is coated with oil, and the section shape and the surface quality of the rolled steel strip are improved; the wear consumption of the roller can be greatly reduced, the service life of the roller is prolonged, and the wear consumption of the roller and the time for changing the roller are reduced;
step four, when the tensioning roller 14 descends, the screw 19 gradually withdraws to the outside of the threaded hole, at this time, the screw 19 does not press the abutting plate 23, so that under the resilience force of the spring 24, the buoyancy sealing plate 20 is initially lifted, when the buoyancy sealing plate 20 ascends, lubricating oil in the oil storage cavity above the buoyancy sealing plate 20 can be pushed into the diversion hole, then the oil body flows back to the oil storage cavity below the buoyancy sealing plate 20 through the diversion hole, after the oil body enters below the buoyancy sealing plate 20, the blocking plug 21 and the buoyancy rod 22 can be pushed to ascend by the oil body, and even when the subsequent resilience force of the spring 24 is reduced, the buoyancy sealing plate 20 can be continuously lifted;
step five, the oil body entering the lower part of the oil storage cavity enters the clamping groove through the shunt pipe, wets the oil permeable layer 27 in the groove, and the oil body flowing out under the action of the oil guide hole can perform oil immersion operation on the oil guide cotton wiper 26, so that the oil guide cotton wiper 26 is saturated in oil absorption, and after the oil body adsorbed in the oil guide cotton wiper 26 is saturated, the oil body in the oil storage cavity can not continuously seep outwards; the oil body can be externally permeated only after the oil body in the oil guide cotton wiper 26 is lack;
step six, because the tensioning roller 14 is in a butt tensioning state on the steel belt, the tensioning roller 14 can be driven to rotate when the steel belt is wound, the oil body absorbed by the oil guide cotton wiper 26 is extruded under the action of the pressurizing convex strips 28 through the rotation of the tensioning roller 14, so that the oil body is coated on the outer wall of the tensioning roller 14, and the single-sided oiling lubrication effect can be achieved before secondary rolling while the steel belt is tensioned; further reducing the friction resistance of the roller when rolling the steel strip;
step seven, after unreeling machine 2 unreels the steel strip and receives, make unreeling machine 2 roll, the rolling machine 3 unreels the steel strip just after rolling, then start driving motor to drive the lower roll 4 to overturn, and then carry out the reverse transport rolling operation of secondary to the steel strip after rolling, and the operation is only to the steel strip of reverse transport through oil feeding mechanism this moment, after rolling through a set of lower roll 4 and upper roll 5, again carry out the oiling lubrication operation of single face, can save the consumption of lubricating oil, simultaneously can carry out make full use of to last lubricating oil that remains on the steel strip, and can carry out the rolling operation repeatedly to and fro to the steel strip, can further avoid the steel strip to lead to the fact the condition emergence of steel strip deformation because of the stress that unidirectional rolling produced when rolling operation.
The foregoing is only a preferred embodiment of the present application, but the scope of the present application is not limited thereto, and any person skilled in the art, who is within the scope of the present application, should make equivalent substitutions or modifications according to the technical scheme of the present application and the inventive concept thereof, and should be covered by the scope of the present application.
