Abstract
The present invention relates to a back-up roll implementing control of plate shape for plate-strip rolling mill. It is mainly composed of cylindrical spindle, roll sleeve, central bearing component installed between spindle and roll sleeve and positioned in the middle of spindle roll body, special-made bearings which are installed between spindle and roll sleeve, left and right symmetrically arranged and respectively equipped with inner ring whose width is continuously changeable and roll holder and spindle phase-angle regulating mechanism. When it is necessary to regulate plate shape, the spindle phase-angle regulating mechanism is used to change the phase-angle of the spindle so as to relatively change supporting width of the back-up roll to attain the goal of regulating plate shape.
Description
The present invention relates to a kind of strip-mill strip that is used for, carry out the back up roll of plate shape control.
In plate sheet and strip was produced, the plate shape of product was a very important quality index.In order to obtain good plate shape, various novel rolling mills and roll occur in succession and have obtained application aborning.
At present, the backing roll with plate shape control ability that adopts on the strip-mill strip adopts hydraulic bending roll or bloated roller mode to change roll crown or roll bearing width more both at home and abroad, the breaker roll accuracy of manufacture and HYDRAULIC CONTROL SYSTEM required precision are higher, and structure is complicated, and cost is also higher.Though the report of the variable roll of mechanical type roll crown was also arranged, yet did not have the report of discovery about the mechanical type continuously variable supporting width backing roll aspect identical with the present invention.
The objective of the invention is to design a kind of backing roll, this backing roll should have following characteristics: simple in structure, cheap, supporting width should be adjustable continuously, bearing capacity is strong, does not need hydraulic system also can realize plate shape On-line Control, and plate shape adjustable range is big, can be conveniently used in the normal four-roller milling train, adopt this backing roll should be able to realize depressing greatly rolling and free regulation rolling.
The said continuously variable supporting width backing roll of the present invention is characterized in: it by cylindrical mandrel (1), roller shell (4), be loaded between mandrel (1) and the roller shell (4) and be positioned at mandrel body of roll middle part axis of centres bearing assembly (3), be loaded between mandrel (1) and the roller shell (4) and inner ring width continuous variable and put up the handtailor bearing (2), the mandrel phase angle governor motion (8) that are symmetrically arranged with the roller maintenance and form; Said handtailor bearing (2) by ring (10) in the outer shroud (5), width continuous variable, be loaded on the retainer (7) between outer shroud (5) and the interior ring (10), roller (6), the end cap (9) that is loaded on the retainer (7) formed; In the width of ring (10) can LINEAR CONTINUOUS variable, also can non-linear continuous variable; Said retainer (7) is extended with the arc supporting spring outside the place, inboard near bearing inner ring, the supporting spring wrap angle can make roller (6) also not break away from outer shroud in the ring place in having between 45 °～55 °; The axis of handtailor bearing (2) and axis of centres bearing assembly (3) does not produce inclination with respect to the axis of mandrel (1); Mandrel during operate as normal (1) does not rotate, and roller shell (4) rotates with working roll; When needs carry out the adjusting of plate shape, adopt mandrel phase angle governor motion (8) to change the mandrel phase angle, thereby correspondingly changed the supporting width of backing roll, reach plate shape and regulate purpose.
Same supporting width (except that maximum or minimum supporting width) is can be by mandrel (1) counterclockwise respectively or clockwise rotate and obtain.Behind the component wear of a half side-view, can make mandrel phase angle backward rotation like this, thereby prolong the service life of each parts.The interior ring of the non-linear continuous variable of employing width can increase the adjustable range of supporting width.The backing roll of Gou Chenging thus, supporting width is adjustable continuously, and bearing capacity is strong, does not need hydraulic system also can realize plate shape On-line Control, and plate shape adjustable range is bigger; By the deformation-compensated plate shape stability that improved, can realize depressing greatly rolling and free regulation rolling, can increase the roller control range having on the milling train of roll-bending device; Simple in structure, cheap, can be conveniently used in the normal four-roller milling train, make it have plate shape control ability.In addition, mandrel can utilize the useless backing roll processing of mill, and can use for a long time.
Drawings and Examples:
Fig. 1 is the continuous adjustable support roll structure of a supporting width schematic diagram
Fig. 2 is a handtailor bearing retainer structural representation
In accompanying drawing 1: (1) is mandrel, and (2) are handtailor bearing, and (3) are axis of centres bearing assembly, (4) be roller shell, (5) are outer shroud, and (6) are roller, (7) be retainer, (8) be mandrel phase angle governor motion, (9) are end cap, and (10) are interior ring, (11) be cooler, (12) be heater, (13) are oil pump, and (14) are fuel tank.
Shown in the accompanying drawing 1 is one embodiment of the present of invention: axis of centres bearing assembly (3) is housed between cylindrical mandrel (1) and roller shell (4) and is the handtailor bearing (2) that is symmetrically arranged, an end of mandrel (1) connects mutually with its phase angle governor motion (5).Axis of centres bearing assembly (3) promptly can bear radial load, also can bear left and right sides axial load.Handtailor bearing by the interior ring (10) of outer shroud (5), width linearity continuous variable, be loaded on the retainer (7) between outer shroud (5) and the interior ring (10), the roller (6) that is loaded on the retainer (7) is formed.Retainer (7) is extended with the arc supporting spring outside the place, inboard near bearing inner ring, the supporting spring wrap angle is 50 °, can make roller (9) also not break away from outer shroud in the ring place in having.The axis of handtailor bearing (2) and axis of centres bearing assembly (3) all keeps level, does not produce inclination with respect to the axis of mandrel (1).Mandrel during operate as normal (1) does not rotate, and roller shell (4) rotates with working roll.Heater (12) and cooler (11) can make the lubricating oil of fuel tank (14) lining keep constant temperature, have oil suction chamber and oil back chamber in the mandrel, and the oil pocket that oil pump (13) is squeezed into lubricating oil in the mandrel is lubricated central bearing assembly (3) and handtailor bearing (2).
When needs carry out the adjusting of plate shape, adopt mandrel phase angle governor motion (8) to change the mandrel phase angle, thereby correspondingly changed the supporting width of backing roll, reach plate shape and regulate purpose.Same supporting width (except that minimum and maximum supporting width) can be by mandrel respectively counterclockwise or clockwise rotate and obtain.Behind the component wear of a half side-view, can make mandrel phase angle backward rotation like this, thereby prolong the service life of each parts.
