The specific embodiment
As shown in Figure 1, the present embodiment slitting line afterbody galvanized steel plain sheet tensioning apparatus comprises lifting pressure roller 1, stationary roll 2 and movable roll 3, also comprises for the hydraulic locking apparatus that described movable roll 3 is locked in the operating position; The diameter of described lifting pressure roller 1 is 200 millimeters, and the diameter of described stationary roll 2 and described movable roll 3 is 500 millimeters.Described stationary roll 2 is between described lifting pressure roller 1 and described movable roll 3; Galvanized steel plain sheet 4 and enters coiling machine 5 between described stationary roll 2 and the described movable roll 3 successively between described lifting pressure roller 1 and described stationary roll 2; Be provided with flexible material (adopt polyurethane in the present embodiment, described lifting pressure roller 1, described stationary roll 2 and described movable roll 3 are polyurethane roller) on described lifting pressure roller 1, described stationary roll 2 and described movable roll 3 and the working face that described galvanized steel plain sheet 4 contacts.
The axis of the axis of the axis of described lifting pressure roller 1, described stationary roll 2 and described movable roll 3 is all on same numerical value plane and be parallel to each other; Described lifting pressure roller 1 is positioned at the top of described stationary roll 2, and described lifting pressure roller 1 can rise or descend by relatively described stationary roll 2 by Driven by Hydraulic Cylinder; Described movable roll 3 is by Driven by Hydraulic Cylinder, and axis that can described stationary roll 2 is the axle rotation.
The transmission side of the transmission side of described movable roll 3 and described stationary roll 2 is respectively arranged with magnetic powder brake, in order to described movable roll 3 and described stationary roll 2 are braked.
Utilize the galvanized steel plain sheet tensioning method for coiling of above-mentioned slitting line afterbody galvanized steel plain sheet tensioning apparatus, comprise the steps:
(a) regulate the threading gap: lifting pressure roller 1 away from stationary roll 2 so that form the gap of passing for galvanized steel plain sheet 4 between the two; Movable roll 3 is the rotary moveable roller, and the rotary moveable roller moves to the galvanized steel plain sheet 4 outlet tops between described lifting pressure roller 1 and the described stationary roll 2, so that form the gap of passing for galvanized steel plain sheet 4 between described rotary moveable roller and the described stationary roll 2;
(b) threading: described galvanized steel plain sheet 4 at first passes between described lifting pressure roller 1 and described stationary roll 2 from the right side, to the left side of described lifting pressure roller 1 and described stationary roll 2; Then enter between described stationary roll 2 and the described movable roll 3 around described stationary roll 2 in described stationary roll 2 left sides, to the right side of described stationary roll 2 and described movable roll 3; At last enter into the coiling machine 5 that is positioned at described movable roll 3 left sides on the right side of described movable roll 3 around described movable roll 3;
(c) tensioning: described galvanized steel plain sheet 4 is nipped behind the described coiling machine 5, and described lifting pressure roller 1 is near described stationary roll 2, so that described galvanized steel plain sheet 4 is pressed between described lifting pressure roller 1 and the described stationary roll 2; Described rotary moveable roller moves to described stationary roll 2 belows, so that described galvanized steel plain sheet 4 is from forming S type parcel district between the described rotary moveable roller below between described lifting pressure roller 1 and the described stationary roll 2.In the galvanized steel plain sheet tensioning method for coiling of the present embodiment, for the ease of threading and realize quick threading, described movable roll 3 take the axis of described stationary roll 2 as axle, is spent to described lifting pressure roller 1 rotation (counterclockwise) 155 in the left side of described stationary roll 2; Described galvanized steel plain sheet 4 is positioned at after pass between described lifting pressure roller 1 and the described stationary roll 2 below the described movable roll 3 when threading like this, then described galvanized steel plain sheet 4 directly enters described coiling machine 5 and the described coiling machine 5 of being nipped, then drop to by the described lifting pressure roller 1 of Driven by Hydraulic Cylinder described galvanized steel plain sheet 4 is pressed between described lifting pressure roller 1 and the described stationary roll 2, and by 3 reverse rotations of the described movable roll of Driven by Hydraulic Cylinder under described stationary roll 2 and by hydraulic locking apparatus with described movable roll 3 lockings, prevent that described coiling machine 5 from batching movable roll 3 described in the process of described galvanized steel plain sheet 4 and being moved or rocking.Described hydraulic locking apparatus can adopt structure well known in the prior art, for example: can utilize the hook on the hydraulic cylinder piston rod to hook the axle of described movable roll 3; Certainly, can take also that other can be locked in described movable roll 3 device of this position in the prior art.
Because described lifting pressure roller 1, described stationary roll 2 and described movable roll 3 are polyurethane roller and described lifting pressure roller 1, described stationary roll 2 and described movable roll 3 all relative sliding can not occur with described galvanized steel plain sheet 4, therefore be conducive to described galvanized steel plain sheet 4 surperficial zinc flower and the plate face fineness of complete reservation, be conducive to realize the threading automation and reduced labor strength, raise labour productivity and product quality.Can not produce impurity on described galvanized steel plain sheet 4 surfaces, thereby not need manually described galvanized steel plain sheet 4 surfaces to be cleared up.
Above-described embodiment only is for the invention example clearly is described, and is not the restriction to the invention specific embodiment.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here need not also can't give all embodiments exhaustive.And the apparent variation of being amplified out thus or change still are among the protection domain of the invention claim.
