Abstract
The utility model discloses an 8-roller mill which is a mill for milling sheets and strips. Middle supporting rollers (3) (6) are respectively arranged between an upper and a lower pairs of backrest supporting rollers (1) (2) (7) (8) which are arranged in parallel along a horizontal direction and work rollers (4) (5); the two middle supporting rollers (3) (6) are driving rollers; both an end head at the drive side of one of the middle supporting rollers (3) (6) and an end head at the operating side of the other of the middle supporting rollers (3) (6) are provided with conical cylindrical sections which can move axially. The utility model has the advantages that the constrictive mark of the backrest supporting rollers is avoided to be reflected on the surfaces of strips, the shape regulating ability is strong, strips with good shapes can be rolled, simultaneously, the replacement of the work rollers is convenient, the time is saved, and the labor is saved.
Description
The utility model relates to a kind of 8 roller mills, is a kind of milling train that is used for the rolled sheet metal band.
At present, the thin plate strip-rolling adopts four-high mill to carry out mostly, but because the backing roll of four-high mill is the simply supported beam of two fulcrums, stressed back produces amount of deflection and causes the rolling extension inequality along the band cross section, and strip material glacing flatness is worsened.For addressing this problem, often on this milling train, set up various plate shape governor motions, as the HC milling train, and, increase the milling train lateral stiffness by increasing the backing roll diameter.But this has increased size, weight and the manufacturing cost of equipment undoubtedly.Sen Shi 6 roller mills of U.S. Sendzimir company are mainly by frame, four back support rollers, two working rolls with hydraulic pressure is depressed, pressuring upper device is formed.The upper and lower back support roller that respectively has a pair of along continuous straight runs to be provided with in the frame, every pair of backing roll intermediate support a working roll.The bearing-surface that back support roller support matches with frame is a cambered surface.The eccentric shaft that the rotating shaft of back support roller support departs from for the rotation with its backing roll itself.Constitute by being contained in hydraulic cylinder that sector gear on the eccentric shaft and piston rod both sides have the tooth bar that is meshed with sector gear that hydraulic pressure is depressed, pressuring upper device.The back support roller becomes the statically indeterminate beam of multi-point support to the simply supported beam of 2 supportings of four-high mill backing roll, and available less backing roll obtains very big lateral stiffness, and compact conformation, size is little, in light weight, cost is low.By the hydraulic cylinder piston rod lifting, the sector gear that is meshed with the piston rod upper rack drives the eccentric shaft rotation, makes the relative folding of a pair of back support roller, and that realizes working roll depresses or press adjusting, convenient and reliable.The existing weak point of this milling train is: because the back support roller is a segmental structure, form impression on working roll, be reacted to strip surface, influence strip quality, as live-roller, cause replacing working roll workload big with working roll, waste time and energy.
The purpose of this utility model provide a kind of can the good thin plate band of rolling ejecting plate shape, and be easy to change 8 roller mills of working roll.
The purpose of this utility model is to realize like this.
A kind of 8 roller mills, have frame, four back support rollers, two working rolls, and depress, press adjusting device by being installed in the hydraulic pressure that hydraulic cylinder that sector gear on the back support roller support eccentric shaft and piston rod both sides have the tooth bar that is meshed with sector gear constitutes, between back support roller that upper and lower two pairs of along continuous straight runs be arranged in parallel and working roll an intermediate support roller is installed respectively, two intermediate support rollers are live-roller.
Two intermediate support rollers, the termination of transmission side that one is individual and another fore side all have one section for the awl cylindricality, can move vertically.
The bearing-surface of back support roller support and the bearing-surface of frame corresponding with it are the plane.
The advantage that the utility model is compared with prior art had is: set up the intermediate support roller, avoid back support roll-in trace to be reacted to strip surface, improved strip quality; But the intermediate support roller is the shift roll that has tapering, has increased the plate shape regulating power of milling train, has further improved strip quality, can the good band of rolling ejecting plate shape.As live-roller, be convenient to the replacing of working roll with the intermediate support roller.Adopt plane contact between back support roller support and the frame, can or wedge compensation adjustment mechanism be set by shimming and adjust the milling train opening degree easily, and can in a big way, change work roll diameter.
Introduce embodiment of the present utility model below in conjunction with accompanying drawing.
Fig. 1 is the structural representation of a kind of 8 roller mills of the utility model.
Fig. 2 is that the roller system of Fig. 1 arranges side view.
As shown in Figure 1, the utility model mainly is made up of the hydraulic cylinder 9,12 that frame 10, four 1,2,7,8, two intermediate support rollers of back support roller 3,6, two working rolls 4,5, sector gear 13 and piston rod both sides have tooth bar.The back support roller 1,2 that upper and lower two pairs of along continuous straight runs be arranged in parallel and 7,8 is supporting working roll 4,5 by intermediate support roller 3,6.Two intermediate support rollers 3,6 are live-roller.The termination of the transmission side of the fore side of last intermediate support roller 3 and following intermediate support roller 6 all has one section to be the awl cylindricality, and can move axially.Whole roller is as shown in Figure 2, is installed in the frame 10.The bearing-surface of the support 11 of back support roller and the bearing-surface of frame corresponding with it 10 are the plane.The eccentric shaft that the rotating shaft 14 of support 11 departs from for the rotation with its back support roller 1,2,7,8.Sector gear 13 is installed on the eccentric shaft 14, is meshed with hydraulic cylinder for reduction system 9 and the tooth bar that presses hydraulic cylinder 12 piston rod both sides respectively.The cylinder body of hydraulic cylinder 9,12 is installed on the frame 10.
Install when adjusting, can be by the opening degree of increase and decrease pad preset milling train between the supporting plane of back support roller support 11 and frame 10.During work, drive two intermediate support rollers 3,6, working roll 4,5 passive rotations are rolled strip, because the horizontal component that moment of torsion transmits roll-force between the horizontal component that is produced lucky and working roll 4,5 and rolled piece between intermediate support roller 3,6 and the working roll 4,5 sternly weighs, and can reduce the roll lateral bending.Hydraulic cylinder for reduction system 9 piston liftings, the rack drives sector gear 13 of piston rod both sides drives eccentric shaft 14 rotations, makes a pair of back support roller 1,2 relative foldings, realizes the adjustment of depressing of top working roll 4.Be used for the roll line adjustment press adjustment process and above-mentioned to depress adjustment process just the same.When plate shape need be adjusted, can move axially intermediate support roller 3,6, plate shape is improved.Owing to adopt intermediate support roller 3,6 as live-roller, when needs are changed working roll 4,5, only need to extract old working roll out, insert new working roll, can finish, very convenient.
