Abstract

Disclosed is a device for bending the rolls in a roll stand comprising several rolls. Said device is provided with bending blocks which are fastened between the built-in roll parts and the stand windows at the delivery end and the discharge end, the top and bottom bending blocks being connected by means of piston cylinders and/or a vertical positioning mechanism, preferably a spindle-type lifting gear unit. A bending force can be introduced into the bending blocks (5, 5a) which are connected on the same side via a piston cylinder (7) while the opposite bending blocks (5', 5a') can be positioned and locked via the spindle-type lifting gear unit.

Description

Low friction bending system in many roll-mill stands
Technical field
The present invention relates to a kind of in many roll-mill stands the device of crooked roll, this device has at feed side and exit side, is fixed between roll assembly parts and the framework window, can be by the crooked assembly of adjusting device loads.
Background technology
Such device is used to adjust the flatness of rolled products as the executing agency that makes working roller bending.In this executing agency the roll seam physical dimension at band seamed edge position is had a direct impact, wherein working roll is around the edge positive curve of its top roller, around the edge hogging bending of rolled piece.
Can know a kind of mill stand from Germany Patent document 22 50 953, it has working roll and backing roll and a roller bending system, in mill stand, be directed between the assembly of the assembly parts of working roll in being anchored on framework window, but and couple together with beidirectional piston-cylinder-system's adjustment working roll body of roll by the assembly outfit, a upward guide piece and a upward guide piece that can vertically be directed are movably wherein all arranged on each assembly, and one of them guiding piece holds cylinder, another guiding piece links to each other with piston, these guiding pieces and assembly parts by the horizontally-guided device in vertical direction form fit be connected, this horizontally-guided device is parallel to roll and extends between support, be used to change roll.Like this, for making the roll bending, two piston-cylinder-systems must be arranged in each side.
It is feasible that this device is proved to be in actual applications.But its shortcoming is must be in transmission side and active side, and all arranges cylinder at feed side and exit side.Because these of each side movably support and produced high frictional force inevitably, this frictional force has adverse effect to the adjustment of flatness in addition.
Summary of the invention
The objective of the invention is to reduce the frictional force in this type systematic.
For realizing this purpose, the invention provides a kind of device that is used at the crooked roll of many roll-mill stands, this device has feed side crooked assembly and exit side crooked assembly, these assemblies are fixed between roll assembly parts and the framework window, can be provided with by adjustment equipment, the crooked assembly of a roll stand has a piston-cylinder, but the crooked assembly of relative roll stand has the system of a perpendicular positioning, it is characterized in that, but the system of described perpendicular positioning is configured to the axle lifting actuator, the wedge that perhaps has the forced guidance device perhaps has the cylinder of chuck and position sensor, perhaps eccentric shaft.
By the device by perpendicular positioning, preferably axle lifting actuator location and locking crooked assembly have produced a pivot, and assembly parts can be around this pivot swing.For the bending force with transmission side and active side imports crooked assembly, also need respectively be equipped with a cylinder.
In mill stand, only use two cylinders that bending force is imported crooked assembly, obviously reduced frictional force thus.
Also compensated the abrading section of roll by this axle lifting actuator.
Also can be used for making central roll bending in the six-high cluster mill support according to device of the present invention.Can also imagine and be used for the reversible mill support.
Description of drawings
One embodiment of the present of invention have been shown in the accompanying drawing.
Fig. 1 shows the side cutaway view of the four-high mill support of seeing from transmission side.
Fig. 2 shows the vertical view on Fig. 1 mill stand working roll plane.
The specific embodiment
In mill stand 1, working roll 3,3a are by backing roll 2, and 2a supports.The assembly parts 4 of working roll, 4a passes through crooked assembly 5,5a, 5 ', 5a ' links to each other with roll stand 6,6 '.Be provided with an axle lifting actuator 10 between crooked assembly 5 ' and 5a ', this transmission device can be by drive unit 12 location and locking.
Crooked assembly 5 links to each other by piston-cylinder 7 with 5a, and the piston 9 of piston-cylinder is bearing in the crooked assembly 5a, and its connecting rod 8 is installed in the crooked assembly 5. Crooked assembly 5,5a, 5 ' and 5a ' on the one hand and working roll 3, the assembly parts 4 of 3a, 4a links to each other, on the other hand with roll stand 6,6 ' links to each other in known manner.
The rolling direction of the rolled piece that passes illustrates by double-head arrow 11.For adjusting flatness, with axle lifting actuator location and locking crooked assembly 5 ', 5a ', the piston-cylinder 7 that simultaneously crooked assembly 5 is linked to each other with 5a imports necessary bending force.
The present invention is not limited to and uses the axle lifting actuator, but can use the mechanism of any perpendicular positioning, for example has the wedge of forced guiding device, has the cylinder or the eccentric shaft of chuck and position sensor.

Claims (3)
