The two ends of described straightening roller device have the seam of adjustable clearance, connect with top roll frame and lower roll frame.
Between the described straightening roller device of going up in roller arrangement and the following roller arrangement hydraulic die cushion is installed.
Be equipped with in the described down roller arrangement compress roller arrangement compress the roller oil cylinder.
Described every smoothing roll is equipped with many row's backing rolls, under the every back-up chock wedge is installed.
Described frame is transmission side and changing side frame, and entablature and sill constitute.
Described transmission side frame and changing side frame can be combination prefastening frame.
Described rotary bracket supporting universal-joint spindle and location, rotary bracket is equipped with hydraulic cylinder, and changing rig is equipped with motor, reductor, hydraulic cylinder.
Between described entrance side pinch roll and the outlet side pinch roll up-down rollers, be separately installed with hydraulic cylinder, the transmission side of down roller is separately installed with motor, reductor, the bottom is equipped with motor, reductor, screw mandrel jack.
Described straightener is equipped with at least one main motor and speed reducer, gear distribution box.
Advantage of the present utility model: owing to taked abovementioned technology, it is strong to make the present invention have the steel plate of rectification ability, correct promptly that the steel plate thickness range is wide, intensity is high, the utility model technology is installed a straightener and just can be satisfied present cut deal steel rolling mill and produce the wide requirement with high-strength steel sheet of steel plate thickness range.If permanent roll spacing straightener is changed into this kind roll gap adjustable flattening machine, the ability of straightening steel plate improves a lot.Fascinating and the steel plate of the rectifiable defective of roller function of smoothing roll at different parts; Wedge under the back-up chock can guarantee that backing roll contacts with smoothing roll well, and is stressed even, the service life of improving smoothing roll, back-up roll bearing; Last bottom pinch roll liftable is also set up stretcher leveling, and rotary bracket is convenient to the maintenance between smoothing roll and the universal-joint spindle; Changing rig realized changing fast advantages such as straightening roller device in about 30 minutes.

Fig. 1 is machine row figure of the present utility model.
Fig. 2 is that the A of Fig. 1 is to front view.
Fig. 3 is that the B of Fig. 2 is to front view.
The specific embodiment
With reference to Fig. 1-Fig. 3, the smoothing roll 15 of one or more main motor 1 in reductor 2 or gear distribution box 3, universal-joint spindle 4, transmission straightening machine body 5 rotates straightening steel plate forward or backwards.(B band arrow represents that entrance side, the other end then are outlet side to entrance side among the figure, as follows) and outlet side pinch roll 7 along roller-way 22 straightening steel plates, they respectively by the motor and speed reducer transmission, be used for transporting steel plate turnover straightening roller device 15, hydraulic cylinder is used in compressing of last bottom pinch roll 7, and in the straightening steel plate process, set up the stretcher leveling steel plate, pinch roll 7 liftings improve the straightening steel plate glacing flatness, realize a straightening steel plate with motor, reductor, the transmission of screw mandrel jack in the straightening steel plate process.(A band arrow represents that changing side, the other end then are transmission side among the figure for the entrance side of last roller arrangement 11 and following roller arrangement 12 and outlet side, transmission side and changing side, as follows) be separately installed with motor 16, worm and wormwheel reductor 17, screw mandrel 18, nut 19 is used for adjusting the distance between the smoothing roll, improves the ability of straightener straightening steel plate, be that the straightening steel plate thickness range is big, the intensity height.Up and down the transmission side of straightening roller device 15 and changing side be separately installed with available pad adjusting play seam, be used for smoothing roll and erect guide effect and locate at the process of transferring spacing and top roll frame and lower roll.Be equipped with between the straightening roller device 15 and prevent the hydraulic die cushion that tightens.Last roller arrangement 11 tops are equipped with four or a plurality of depress oil cylinder 10, can realize that roller arrangement 11 fascinates along entrance side or outlet side, transmission side or changing side direction, and there is the steel plate of different defectives in aligning.Depress oil cylinder 10 also can be realized the overload protection.The entrance side of following roller arrangement 12 and outlet side, transmission side and changing side be equipped with upwards compress roller arrangement 11 compress roller oil cylinder 21, roller arrangement 11 contacts with the tight of last walking beam 9 in the realization, and the bending straightening roller effect that realizes going up roller arrangement 11 and following roller arrangement 12, there is the steel plate of different defectives in aligning.Smoothing roll quantity is no less than seven, up and down interlaced arrangement.Every smoothing roll is equipped with many row's backing roll devices 20, in the bearing block bottom of this device 20 paired wedge is installed, be used for adjusting the contact position between backing roll and smoothing roll, guarantee that every backing roll contacts with smoothing roll, make smoothing roll, backing roll and shaft strength even, improve service life.Frame 8 is made up of monoblock type transmission side frame and changing side frame, entablature, sill, and it is in light weight, precision is high, good rigidly, easy to process.Transmission side frame and changing side frame also can be made into combination prefastening frame, make its convenient transportation.Smoothing roll in last roller arrangement 11 and the following roller arrangement 12 can be by one or more main motor 1, reductor 2 groupings or transmission separately.Steel plate can be set up stretcher leveling in the aligning process, between smoothing roll like this, and realizes that the sharing of load between every or every group of smoothing roll is even, the life-span of improving smoothing roll, backing roll, bearing, universal-joint spindle 4.Balancing cylinder 13 is realized going up walking beam 9 gravity overbalance and is moved up and down, also eliminates the gap of going up between walking beam 9 and the depress oil cylinder 10.Changing rig 6 is by motor, reductor transmission, and roller arrangement 11 and following roller arrangement 12 draw in or pull out frame 8 in the realization, and traversing outside frame, and hydraulic cylinder is used for traversing changing rig 6, the realization fast roll changing.Be installed in the rotary bracket 14 on the transmission side frame, when roll change,, be used for supporting and fixing universal-joint spindle 4 by hydraulic cylinder rotation and lifting.
