The present invention is owing to take above technical scheme, and it has the following advantages:
1. working stand rigidity is high.
2. roll bearing is stressed little, and the life-span is long.
3. the roll barrel lateral stiffness is high, and sag curve is adjustable.
4. can control to multiple bad plate shape, be convenient to regulate.

The specific embodiment
Below in conjunction with accompanying drawing the present invention is carried out detailed description.
Like Fig. 1, shown in Figure 2, a kind of variable amount of deflection four-high mill comprises working stand 1, rolling line adjusting device 2, following supporting roller bearing seat 3, following backing roll 4; Bottom working roll bearing block 5, bottom working roll 6, top working roll bearing block 7, top working roll 8, last supporting roller bearing seat 9, last backing roll 10, oil film contact block 11, depress oil cylinder 12 and roller system 13, working stand 1 is the monoblock cast formula, fuselage is four uiform section columns; Each connects as one with crossbeam up and down, in the inner symmetry of entablature five depress oil cylinders 12 has been installed, and the piston rod end of depress oil cylinder 12 is a sphere shape; And be connected with oil film contact block 11, the arcwall face of oil film contact block 11 directly acts on backing roll 10 body of roll upper faces, the machined unthreaded hole of oil film contact block 11; And with the arcwall face of oil film contact block 11 on the oil groove processed be communicated with, connect hydraulic oil during work, to form the static pressure oil film; Last backing roll 10 is installed in the supporting roller bearing seat 9; Top working roll 8 is installed in the top working roll bearing block 7, and bottom working roll 6 is installed in the bottom working roll bearing block 5, and following backing roll 4 is installed in the lower supporting bearing seat 3; Top working roll bearing block 7 is all processed bossed fin with bottom working roll bearing block 5 both sides; Roll-bending device 13 effect is on it, the adjustment belt plate shape in real time that matches with depress oil cylinder 12 in the operation of rolling, bottom working roll 6 and top working roll 8 equal diameter equal lengths; Can mutual alternative; Following backing roll 4 barrel diameters are greater than last backing roll 10 barrel diameters, and lower supporting bearing seat 3 belows are pressed against on the rolling line adjusting device 2, and rolling line adjusting device 2 is installed in the window bottom of working stand 1.
Operation principle of the present invention is:
When rolling, the present invention regulates the depress oil cylinder 12 of diverse location and implements different drafts according to the different plate shape of band situation, makes backing roll 10 bodies of roll form different sag curves, and then to there being the roll gap of carrying to control, produces the good cold-strip steel of ejecting plate shape.Depress oil cylinder 12 initialization positions are as shown in Figure 3, and the drafts of five oil cylinders is identical, and last backing roll 10 bodies of roll are straight.When monolateral wave appearred in the band steel, adjustment depress oil cylinder 12 was as shown in Figure 4, and a side cylinder drafts that monolateral wave occurs reduces, and all the other oil cylinder drafts increase successively.When bilateral wave appearred in the band steel, adjustment depress oil cylinder 12 was as shown in Figure 5, and middle oil cylinder increases drafts, and all the other oil cylinder drafts center symmetries reduce successively.During wave, adjustment depress oil cylinder 12 is as shown in Figure 6 in the band steel occurs, and middle oil cylinder reduces drafts, and all the other oil cylinder drafts center symmetries increase successively.When 1/4th waves appearred in the band steel, depress oil cylinder 12 was as shown in Figure 7, and centre and both sides oil cylinder increase drafts, and all the other two oil cylinder drafts reduce.
The present invention relies on a plurality of depress oil cylinders of adjusting to adjust belt plate shape, and control mode is simply direct, and mill stiffness is high, is easy to produce high-precision band.
