Before the operation principle to the utility model embodiment illustrates, first to the condition of coming into operation, regulated quantity and tune
Section frequency illustrates.Wherein, the condition of coming into operation is：Milling train necessarily is under continuous rolling pattern；Mill speed is higher than 100mpm
(every point of rice).In order to prevent between rack both sides tensometer gathered data mistake, rolling force deviation of the setting in the rack be more than
30 ton hours, active side automatic adjustment, which tilts, not to be put into；When the rolling force deviation in rack is less than -30 ton hours, driving side is adjusted automatically
Section is tilted and is not put into.In the present embodiment, if the tension variation between rack is between 0.5 ton to -0.5 ton, it is believed that band between rack
Steel state is normal.If the tension variation between rack is more than 0.7 ton or less than -0.7 ton, strip has slight race between illustrating rack
Partially, it needs to be adjusted.Therefore, regulated quantity is limited to：When the tension variation between rack is more than 0.7 ton hour, adjusting active side
It tilts, tension variation, which is adjusted to 0.5 ton or less, to be stopped adjusting；When the tension variation between rack is less than -0.7 ton hour, adjusting driving
It rolls tiltedly, tension variation, which is adjusted to -0.5 ton or more, to be stopped adjusting.It should be noted that the adjusting frequency of tension variation should fit
Preferably, it adjusts unsuitable too fast or excessively slow.If adjusting is too fast, tension variation overshoot can be caused, shaken；If adjusting slow, meeting
Lead to tension variation automatic adjustment failure, is likely to result in broken belt.Therefore, by the utility model embodiment to tension variation into
Row adjust adjusting frequency be：0.2s, interval 0.2s are adjusted, then adjusts 0.2s, until tension variation returns normally.
The process that tension variation is adjusted by the utility model embodiment is as follows：
It first passes through the first tension monitoring component 2 and the second tension monitoring component 3 detects active side and drive between rack respectively
The tension of dynamic side, and the tension data detected is sent to controller, calculate the tension of active side and driving side between rack
Deviation.When the tension of the warp tension ratio driving side of active side between rack is big, illustrate strip to active side sideslip, it should adjust work
It rolls tiltedly, strip is made to be moved to driving side；Conversely, if the tension of the warp tension ratio active side of driving side is big, illustrate strip to driving
Side sideslip, it should adjust driving side inclination, strip is made to be moved to active side.Specifically, according to the scheduled condition that comes into operation, regulated quantity
With adjusting frequency, controller is output to the first power cylinder 4 and/or the second power cylinder 5 by trigger signal is adjusted.First power cylinder 4
And/or second power cylinder 5 act, drive breast roller 1 lift, to change the roll gap of active side and driving side so that work
The tension of the strip of side and driving side changes, and quickly tension variation is adjusted within setting range.In the present embodiment,
After tensioned deviation between rack, the inclination for adjusting previous rack is needed, such as：It is inclined that tensometer between 3-4# racks measures tension
Difference is excessive, needs to carry out tension variation adjusting to 3# racks.What needs to be explained here is that also passing through the first pressure measurement component 8 and
Two pressure measurement components 9 are respectively monitored the pressure of the power end of the first power cylinder 4 and the second power cylinder 5, and will monitor
Pressure data is sent to controller, and calculating is converted into roll-force, to be monitored to the roll-force of active side and driving side.This
Outside, the stretching for also overhang of the piston rod of power cylinder being monitored by magnetic scale and/or displacement sensor, and being monitored
Amount is sent to controller, to which the overhang of the piston rod to power cylinder is monitored.In the adjustment process of tension variation, machine
Have between the overhang of the piston rod of tension variation, rolling force deviation in frame between active side and driving side and power cylinder certain
Relationship, if the direction phase in the direction of tension variation regulated quantity and rolling force deviation or the overhang of the piston rod of power cylinder
Instead, just illustrate scene monitoring component is wrong or strip malposition, at this moment can send out alarm by warning device,
It adjusts after needing operative employee to confirm, is normally carried out with ensureing that the tension variation between rack adjusts operation again.
【Technique effect】
1, pass through the first tension monitoring component 2 and the active side to rolling mill roll 1 and the drive respectively of the second tension monitoring component 3
The tension of dynamic side is monitored, and the tension obtained according to monitoring obtains tension variation.When tension variation is larger, control first is dynamic
Power cylinder 4 and/or the action of the second power cylinder 5, drive rolling mill roll 1 to lift, to change the roll gap of active side and driving side so that
The tension of the strip of active side and driving side changes, and tension variation is adjusted within setting range, existing to solve
In technology when the tension variation between rack between active side and driving side is excessive, operative employee is needed to adjust inclining for roll 1 manually
The technical issues of gradient, not only avoids the hair of milling train sideslip broken belt situation caused by due to operative employee adjusts manually not in time
It is raw, be conducive to being normally carried out for production.And the generation of human error is also avoided, it realizes and is opened between accurately adjusting rack
Power.In addition, the time for also eliminating tension variation of the operative employee between adjusting rack due to paying, to improve the work of operative employee
Make efficiency.
2, the utility model embodiment provides the mode that the overhang of two kinds of piston rods for power cylinder is monitored,
So as to be selectively monitored to the overhang of the piston rod of power cylinder, and then the working condition of power cylinder is carried out
Monitoring.
3, it by the use to the first pressure measurement component 8 and the second pressure measurement component 9, is realized respectively to 4 He of the first power cylinder
The monitoring of pressure, is furthermore achieved the monitoring to the working condition of power cylinder at the power intake of second power cylinder 5.
4, by the use to controller, the automatization level of the utility model embodiment is improved, to improve this
The working efficiency of utility model embodiment.
The utility model embodiment can quickly and efficiently automatically adjust tension variation, very big for preventing high speed broken belt from having
Help.The utility model embodiment has the characteristics that quick, accurate and convenient.
Although the preferred embodiment of the utility model has been described, once a person skilled in the art knows basic
Creative concept, then additional changes and modifications may be made to these embodiments.It is wrapped so the following claims are intended to be interpreted as
It includes preferred embodiment and falls into all change and modification of the scope of the utility model.
Obviously, those skilled in the art can carry out the utility model various modification and variations without departing from this practicality
Novel spirit and scope.If in this way, these modifications and variations of the present invention belong to the utility model claims and
