Description
Technical field
The present invention relates to cold-strip steel tension adjustment technical fields more particularly to a kind of cold-strip steel intelligently to be opened with dancer roll
Power adjustment equipment.
Background technology
It is very strict to the tension force requirement of strip on large high-speed continuous belt steel processing line, especially require stove
The stability contorting of interior strip tension, because being run under hot conditions of the steel band in annealing furnace, the plasticity of steel band significantly increases, this
Steel band sectional area is caused to shrink, narrowed width.It puts into practice operating experience and shows that under fixed tension steel band becomes in stove
Narrow value is raised with furnace temperature and increased.To avoid sectional area contraction at high temperature excessive or broken belt accident occurring, should be heated in steel band
Suitably change the tension of steel band with the raising of temperature of steel strips in the process.Reach this purpose, depend the tension before and after stove alone
Roller is inadequate to control, and usually requires that and special mechanical equipment is set to control and compensate stove internal tension.Dancer roll is just
It is such a special equipment.
The content of the invention
In order to solve technical problem present in background technology, the present invention proposes a kind of cold-strip steel dancer roll intelligence
Tension adjustment equipment, simple in structure, easy to operate, solving strip tension when stove internal cause temperature is raised and lowered can not carry out
The problem of intelligent control and compensation, improve the quality of production and production efficiency.
A kind of cold-strip steel proposed by the present invention dancer roll intelligent tension adjustment equipment including support base, linking arm, is put down
Weight, dancer roll, swing arm, cylinder, cylinder control valve, the first controller, second controller, the first limit switch and second limit
Switch, linking arm is horizontally disposed, and balance weight, dancer roll are separately positioned on linking arm both ends, the centre position of linking arm
It is rotatably connected on the top of support base and by swing arm linking arm is driven to deflect, swing arm is equipped with the angle position of acquisition swing arm deflection
Displacement sensor, the end of swing arm are connected with cylinder, and cylinder is connected by cylinder control valve with source of the gas, dancer roll and entrance jockey pulley
Between cold-strip steel be equipped with detection strip tension tension sensor, the same cylinder control valve of the first controller, tension sensing
Device connects, and the first controller receives the data of tension sensor acquisition and drives swing rod that linking arm is driven to send out by cylinder control valve
Raw deflection；Entrance jockey pulley with the driving device of its strip delivery rate is controlled to connect, open by the first limit switch and second limit
Close and be symmetricly set on the upper and lower ends of dancer roll, the same angular displacement sensor of second controller, driving device, the first limit switch and
Second limit switch connects, and dancer roll is run to when offseting with the first limit switch or the second limit switch, second controller control
Driving device processed adjusts the delivery rate of entrance jockey pulley, by angular displacement sensor cylinder control valve is controlled to reach swing rod movement
It is located to balance weight and dancer roll in same horizontal line.
Preferably, dancer roll is connected by bearing block with linking arm.
Preferably, the length of linking arm is a, and the length of swing arm is b, b ＜ a/2.
Preferably, cylinder includes rod chamber and rodless cavity, and rod chamber and rodless cavity are connected by cylinder control valve and source of the gas
It connects.
Preferably, the line between the first limit switch and linking arm midpoint, the second limit switch and linking arm midpoint it

A kind of cold-strip steel provided by the invention dancer roll intelligent tension adjustment equipment, dancer roll are used to compensate cold-rolled strip
The tension of steel, the cold-strip steel between dancer roll and entrance jockey pulley are equipped with tension sensor, for detecting into stove
Strip tension, the variation of the cold-strip steel tension that the first controller is measured according to tension sensor adjust gas come cylinder control valve
The air pressure of cylinder rod chamber, rodless cavity, when the cold-strip steel tension that tension sensor measures becomes larger, the first controller passes through cylinder control
The piston rod of valve control cylinder processed is retracted, and dancer roll is lifted up, shortens entrance jockey pulley to stove strip running route, release
Release the shrinkage of strip in strip compensation stove；Vice versa, if strip is due to the factors elongation such as temperature rise, at this time tension
The cold-strip steel tension that sensor measures becomes smaller, and dancer roll is fallen downwards under the control of the first controller, increases entrance tension
Roller absorbs strip elongation in stove, keeps tension stability to the strip running route length of stove.It is symmetricly set on dancer roll
The first limit switch, the second limit switch of downside adjust stroke for limiting dancer roll, as dancer roll position is moved to upside
The first limit switch when, the first limit switch send signal and by second controller control entrance jockey pulley increase speed,
Ribbon amount is sent in increase, while swing arm is equipped with angular displacement sensor, and second controller is according to angular displacement sensor fed back values, control
Dancer roll, which is back to, to be located at balance weight in same horizontal line；When being moved to the second limit switch such as dancer roll position, the second pole
Limit switch sends signal, and second controller control entrance jockey pulley reduces speed, and ribbon amount is sent in reduction, at the same second controller according to
Angular displacement sensor fed back values, control dancer roll, which is back to, to be located at balance weight in same horizontal line.
