Abstract
The invention discloses an intermediate roll of a leveling machine, and relates to structural improvement of the intermediate roll of a sextuple leveling machine. The intermediate roll is supported by adjacent supporting rolls on the leveling machine, wherein the two end heads of the intermediate roll correspond to positioning plates on support saddles on the two sides of the leveling machine and provided with movable bulb mechanisms respectively; each movable bulb mechanism comprises a shaft head with a spherical crown-shaped end face and a bearing; and the shaft head is movably connected with the end head of the intermediate roll by the bearing. The intermediate roll changes the structural mode of a fixed bulb at the end head of the intermediate roll into a movable spherical shaft end structure. When the intermediate roll bears the axial force, the spherical shaft head contacts the positioning plates without friction while realizing horizontal positioning of the intermediate roll and can also ensure free rotation of the intermediate roll. The intermediate roll has the advantages of prolonging the service life of machine elements and improving the efficacy of the equipment, along with high reliability.
Description
Technical field
The present invention 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.
Summary of the invention
The present invention is directed to above problem, a kind of wear extent that reduces between intermediate calender rolls roller head and the location-plate is provided, thus the intermediate calender rolls of the levelling machine that increases the service life.
Technical scheme of the present invention 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 present invention 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 present invention has prolonged the service life of parts, and the reliability height has improved equipment effectiveness.
