Abstract
A roll bending-adjustable precision leveling machine relates to a leveling machine and solves the problem that a transversely-bent or buckled plate cannot be leveled by a general leveling machine. The roll bending-adjustable precision leveling machine comprises a machine base and a leveling unit which is mounted on the machine base and comprises a plurality of leveling rolls; and the leveling unit comprises a work roll, an intermediate roll and a support roll. The roll bending-adjustable precision leveling machine is characterized in that the support roll is fixed in a support roll seat; the bottom surface of the support roll seat is a cambered surface which is attached to an intermediate oblique block of which the upper part is provided with a cambered groove; a groove is arranged below the intermediate oblique block; a base oblique plate is arranged in the groove; two ends of the intermediate roll are fixed by a bearing and a shaft sleeve which can move along the axial direction; two ends of the work roll are fixed on a movable support seat; the movable support seat is fixed on a fixed support seat through a screw and a disk spring; and the contacted surface between the movable support seat and the fixed support seat is of an arc shape. According to the roll bending-adjustable precision leveling machine disclosed by the invention, the support roll seat of which the bottom surface is a cambered surface is additionally arranged below the support roll, the deformation of the plate can be increased by adjusting the bending degree of the leveling roll at the buckled plate and the effect of leveling the plate is achieved by eliminating the internal stress of the plate.
Description
Technical field
the present invention relates to a kind of levelling machine, specifically adjustable roll bending formula precision leveling machine.
Background technology
The flatness of
the smoothing precision of levelling machine and the rigidity of crossbeam and straightener roll system is closely related.Usually levelling machine roller system is nonadjustable; Levelling machine can only be smoothed the buckling of plate and slight transverse curvature distortion like this; Occur the problem that transverse curvature is big or wooden dipper is bent easily for the bad cold-reduced sheet of rolling quality, corrosion resistant plate and aluminium alloy plate, present levelling machine can not solve the smoothing of the big or wooden dipper bent plate material of transverse curvature.
Summary of the invention
the object of the present invention is to provide a kind of adjustable roll bending formula precision leveling machine, solve the problem that common levelling machine can not be smoothed the big or wooden dipper bent plate of transverse curvature.
The technical solution adopted for the present invention to solve the technical problems is: adjustable roll bending formula precision leveling machine comprises support, the smoothing unit that is installed on the support and is made up of several straightener rolls; The smoothing unit comprises working roll, intermediate calender rolls and backing roll; It is characterized in that described backing roll is fixed on and supports in the roller seat, support the roller seat bottom surface and be the middle skewback that cambered surface and top has arch groove and fit; Middle skewback below is provided with groove, is provided with end skewback in the groove; The two ends of intermediate calender rolls are fixed through bearing and axially displaceable axle sleeve, and the working roll two ends are fixed on the movable bearing support, and movable bearing support is fixed on the hold-down support through screw rod and disk spring, and the contact-making surface of movable bearing support and hold-down support is an arc;
Described backing roll is fixed on through self-aligning roller bearing and supports in the roller seat;
described intermediate calender rolls is the thin roller with toughness.
the invention has the beneficial effects as follows: through below backing roll, increasing the support roller seat that the bottom surface is a cambered surface; Can eliminate the effect that its internal stress reaches the smoothing plate at the camber increase of the wooden dipper bent plate material place adjustment straightener roll deflection of plate here.

Fig. 4 is the partial enlarged drawing of Fig. 1.
Among
figure: 1 working roll, 2 intermediate calender rolls, 3 backing rolls, 4 support roller seat, 5 middle skewbacks, 6 end skewbacks, 7 movable bearing supports, 8 hold-down supports, 9 screw rods, 10 disk springs, 11 motor reducers, 12 leading screws.
The specific embodiment
Like Fig. 1, Fig. 2, Fig. 3; Shown in Figure 4, adjustable roll bending formula precision leveling machine comprises support; The smoothing unit that is installed on the support and constitutes by several straightener rolls, the smoothing unit comprises working roll 1, intermediate calender rolls 2 and backing roll 3, described backing roll 3 is fixed on and supports in the roller seat 4; Support roller seat 4 bottom surfaces and be the middle skewback 5 that cambered surface and top has arch groove and fit, middle skewback 5 belows are provided with groove, are provided with end skewback 6 in the groove; End skewback 6 can not move by along continuous straight runs like this, but can move in the vertical direction; The two ends of intermediate calender rolls 2 are fixed through bearing and axially displaceable axle sleeve, and working roll 1 two ends are fixed on the movable bearing support 7, and movable bearing support 7 is fixed on the hold-down support 8 through screw rod 9 and disk spring 10, and movable bearing support 7 is an arc with the contact-making surface of hold-down support 8;
Described backing roll 3 is fixed on through self-aligning roller bearing and supports in the roller seat 4;
The thin roller of
described intermediate calender rolls 2 for having toughness.
can be adjusted a certain row's backing roll group separately when the adjustment roll bending; Motor reducer 11 is through skewback 6 at the bottom of leading screw 12 horizontal adjustment; The displacement that end skewback 6 produces horizontal direction promotes middle skewback 5, supports the displacement that roller seat 4 produces vertical direction, reaches the purpose of vertical adjustment backing roll 3; Backing roll 3 bending intermediate calender rolls 2 also are transmitted on the working roll 1; Make working roll 1 bending reach the purpose of smoothing plate local deformation, increase the deflection of plate here, eliminate the effect that its internal stress reaches the smoothing plate.Backing roll 3 will tilt along with the bending of intermediate calender rolls 2 when adjusting separately, and at this moment the cambered surface of 3 bottom surfaces of backing roll is just followed its inclination; Simultaneously, working roll 1 is crooked but its bearings at both ends can be crooked, therefore; The movable bearing support 7 at working roll 1 two ends is an arc with the contact-making surface of hold-down support 8; Make movable bearing support 7 follow working roll 1 adjustment, compression disk spring 10 makes working roll 1 bearings at both ends be unlikely to stressed excessive and damage
