The unsteady deviation correcting device of single roller link-type
The utility model relate to a kind of in tinuous production the deviation correcting device of band, specifically relate to a kind of stainless steel roll bending continuous annealing pickling lines and continuous band of being used for and handle single roller link-type on line deviation correcting device that floats.
Continuous annealing pickling unit is the stainless steel annealing pickling lines with international most advanced level; Level of automation is very high; The band steel is about more than 1600 meter (about 590 meters of pickling line length) in continuous annealing pickling unit, the unit process speed is up to 80m/min, if the band steel departs from the unit medullary ray; Just might cause damage, move particularly important in the unit central position so guarantee the band steel with steel or production unit.For fear of strip running deviation; Need rectify a deviation to the band steel; At present the method for correction has two kinds: a kind ofly be, through oil cylinder the correction roller moved up and down the purpose that reaches correction, this mode exists that the correction reaction is slow, time length, weak effect, cause defective such as tole distortion easily; Another kind is, through oil cylinder the correction roller carried out the purpose that move left and right reaches correction, and this mode also exists takes up an area of big, reaction and abrade surface of steel plate slowly, easily.
The utility model content
The unsteady deviation correcting device of single roller link-type that the utility model technical problem to be solved is to provide a kind of reacts fast, rectifying effect is good.
The utility model solves the technical scheme that its technical problem adopted: single roller link-type deviation correcting device that floats; Comprise the correction permanent seat; Above said correction permanent seat, be provided with the float frame, on said float frame, be provided with a pair of correction roller seat, the correction roller is installed on said correction roller seat; The left and right sides of float frame is connected with the correction permanent seat through hinge assemblies, and the place ahead of said float frame is connected with the correction permanent seat through the correction oil cylinder; On four angles of float frame, lower railway is installed, on said lower railway, roller is installed, at four angles of correction permanent seat the roller mount pressing plate is installed, said roller is arranged in the roller mount pressing plate.
As the improvement of technique scheme, on said correction permanent seat, be provided with journal stirrup, an end of said correction oil cylinder is connected on the journal stirrup.
As another improvement of technique scheme, on correction permanent seat and float frame, hinge seat is installed all, said hinge assemblies is installed on the hinge seat.
The beneficial effect of the utility model is: take up an area of for a short time, correction reaction is fast, can not abrade surface of steel plate in the correction process, can not cause the thin plate distortion.
Description of drawings
Fig. 1 be the utility model structural representation;
Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is the left view of Fig. 1.
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
With reference to Fig. 1, single roller link-type deviation correcting device that floats comprises correction permanent seat 1, above correction permanent seat 1, is provided with float frame 2, on float frame 2, is provided with a pair of correction roller seat 3, and correction roller 4 is installed on correction roller seat 3.The left and right sides of float frame 2 is equipped with hinge seat, in correction permanent seat 1 corresponding position hinge seat is installed also, between the hinge seat on hinge seat on the float frame 2 and the correction permanent seat 1, hinge assemblies 6 is installed.The place ahead of float frame 2 is connected with correction permanent seat 1 through correction oil cylinder 7, on correction permanent seat 1, is provided with journal stirrup 8, and correction oil cylinder 7 one ends are connected the place ahead of float frame 2, and the other end is connected on the journal stirrup 8.On four angles of float frame 2, lower railway 9 is installed, roller 10 is installed on lower railway 9, at four angles of correction permanent seat 1 roller mount pressing plate 11 is installed, roller 10 is arranged in the roller mount pressing plate 11, with limiting roller 10 scope of activity.
The principle of work of the utility model is: carry out Continuous Tracking by detecting head and measure band steel position; To be with the steel position error signal to be input to control unit; System is carried out signal processing; Output current signal is controlled servo-valve, through servo-valve control cylinder action, adjusts the position of band steel thereby the float frame is moved.
The utility model is realized the motion of float through the mechanism of approximate four connecting rods, thereby adjusts the position of band steel, and it reacts soon, takes up an area of little, can not cause that in the correction process tole is out of shape, and can not abrade surface of steel plate yet.
