Abstract
A middle roll of leveling machine relates to an improvement of a middle roll structure of a sixfold type leveling machine. The middle roll is supported by neighboring supporting rolls on the levelingmachine, two end sockets respectively correspond to locating plates on support stands on two sides of the leveling machine, two end sockets of the middle roll are respectively provided with movable ball head mechanisms, the movable ball head mechanism comprises a spindle nose with a spherical cap shaped end surface and a bearing, and the bearing movably connects the spindle nose and the end socketof the middle roll. The middle roll of leveling machine changes the existing structure mode of a fixed ball head on the end socket of the middle roll into a movable ball-shaped spindle nose structure, when the middle roll bears the axial force, the ball-shaped spindle nose realizes transverse locating of the middle roll, is not rubbed and contacted with the locating plates simultaneously, and canensure free rotation of the middle roll. The middle roll of leveling machine prolongs the service life of machine components, has high reliability, and improves the device efficiency.
Description
Technical field
The utility model relates to the improvement of sixfold formula levelling machine intermediate calender rolls structure.
Background technology
The straightener roll 1 of sixfold formula levelling machine (as Fig. 1,3) is movably connected on the bearing 6 of fuselage both sides, because axial length is longer, sheet thickness, the out-of-shape of being smoothed need be to straightener roll 1 segmentation adjustment, so adopted many groups backing roll 5 to realize the segmentation adjustment.But organize backing roll 5 as directly acting on the straightener roll 1 more, can produce damage to the surface of straightener roll 1 again, therefore, between straightener roll 1 and backing roll 5, float and be provided with intermediate calender rolls 4, the variation of backing roll 5 height and positions realizes by the strain of intermediate calender rolls 4, remake use with straightener roll 1 on, the plate with shape, thickness error is smoothed realizing.Intermediate calender rolls 4 is stated in the course of action in realization axial moving can occur, and for limiting the distance that it moves, is provided with location-plate 2 respectively on side supports, and the roller head 7 of intermediate calender rolls 4 is arranged to bulb-type, to adapt to the requirement of intermediate calender rolls 4 irregular movements.But find in the practical application that the unidirectional axial thrust load of intermediate calender rolls 4 carrying sometimes is very big, when intermediate calender rolls 4 rotated, frictional force was very big between the spherical surface of roller head 7 and the location-plate 2, causes wear extent bigger, and needs are more roll change 7 frequently.
The utility model content
The utility model provides a kind of wear extent that reduces between intermediate calender rolls roller head and the location-plate at above problem, thus the intermediate calender rolls of the levelling machine that increases the service life.
The technical solution of the utility model is: it is supported by backing roll adjacent on the levelling machine, two ends is corresponding with location-plate on the levelling machine side supports respectively, two ends at intermediate calender rolls is respectively equipped with the movable balls head mechanism, described movable balls head mechanism comprises spindle nose and the bearing with a spherical end face, and bearing flexibly connects spindle nose and intermediate calender rolls termination.
It also comprises gland and sealing ring, and gland is fixedlyed connected with the spindle nose bottom surface, and sealing ring is arranged between gland and the intermediate calender rolls termination.
The utility model has changed the tactic pattern of the fixed bulb in intermediate calender rolls termination in the past, changes movable spherical spindle nose structure into.When intermediate calender rolls carrying axial force, spherical spindle nose and does not have CONTACT WITH FRICTION between the location-plate when realizing the intermediate calender rolls located lateral, can also guarantee that intermediate calender rolls freely rotates.The utility model has prolonged the service life of parts, and the reliability height has improved equipment effectiveness.
