Definitions

  • the invention relates to a roll stand with vertically displaceable in the windows of its stands, the bearing of rollers having chocks.
  • Such chocks are usually guided between wear-lining liners or between wear plates of cylinder blocks projecting into the windows.
  • Such linear guides not only require a relatively high production effort, which is further increased by the relatively narrow tolerances within which the specified fits can be achieved;
  • Such linear guides require also influenced by the high contact forces, if appropriate, to the wear plates of the F üh- stanchions, undesirably high friction forces which interfere appear in changing directions of movement at the establishments and regulations as hysteresis forces with changing directions.
  • rollers are to be positioned normally to the vertical center plane of the stands, it is necessary to assign additional adjusting devices to the respective opposing wear plates, which are able to shift the opposing wear plates in the same direction by the same amounts, in the interest of maintaining the specified play as well as avoiding canting, particularly high requirements must be met.
  • the invention is therefore based on the object of specifying a guidance of the chocks of Naiz scaffolding within the upright window, which requires only little construction effort, and in which the friction forces which occur are low, and which furthermore allows simple means, even normal vertical center plane of the stand directed adjusting movement.
  • eccentric bolts are used both for bolts equipped with an eccentric and for eccentric bushings equipped with an eccentric that can be pivoted or rotated about a pin.
  • the setting of the eccentrics is simplified if the adjusting drive devices are assigned to the eccentric bolts.
  • the eccentric bolts or eccentric bushings rotatable about pins can have worm wheels that can be driven by screws.
  • eccentric bolts or eccentric bushings which can be pivoted about pins can be adjustable by pressure medium cylinders via toothed rack-and-pinion pairs or via levers connected to them.
  • a relatively simple structure results and the number of actuating cylinders required is restricted if actuating cylinders with more than one toothed rack or actuating rod which is operatively connected by a number of eccentric bolts arranged one above the other are arranged downstream.
  • a common rack or a common actuating rod can attack actuating levers which are connected to the two links of a pair of links. It is also possible to actuate the handlebars together which guide the rollers of the same type, i.e. the work rollers or the intermediate rollers of a stand, and finally the eccentric bolts of all the handlebars on one side of the stand can be adjusted via a common rack or adjusting rod, and there is also a common one Control or mechanical coupling of screws causing a drive possible.
  • the handlebars can be designed as double-armed levers, on the free lever arms of which pressure medium cylinders act.
  • additional pressure medium cylinders it is possible to exert additional forces on the chocks which are able to act as bending forces on the roller journals and / or it allow to achieve a balance by taking over the weight of the upper roll internals.
  • the mutually facing surfaces of the chocks and the guide pieces step back with increasing distance from the horizontal plane of symmetry, so that the guide allows a certain freedom of movement and, if necessary, also compensating pivoting movements if mutually opposing guide pieces acting together on a chock take up different height settings, which during an actuating process could occur.
  • Fig. 1 the middle sections of the uprights 1 of a upright of a scaffold are shown broken off, which enclose a window 2 between them.
  • the chocks 3 and 4 of two work rolls are shown, which are held by means of links 7, 10 and 11 pivotable about pivot pins 5 and 6, two of which always attack one side of a chock and with the distances the swivel pin 5 of the chock and the swivel pin 6 of a stator bar 1 form a parallelelogram transmission which ensures a translational movement of the guided chock.
  • the links 7 and 11 are each equipped with a second lever arm 8, and the cylinder end and the piston rod head of a hydraulic cylinder 9 are articulated to the free ends of the free levers. This makes it possible to impart preloads to the chocks, which act in the sense of a balance, possibly also in the sense of a work roll bend.
  • the pivot pin 6 can be designed as an eccentric pin 14 which is mounted in a bushing 13 provided in a recess in a stator bar 12.
  • the eccentric bolt 14 has a worm wheel 15, in which a worm 16 provided on a drivable worm shaft engages, and the shaft of the eccentric bolt 14 continues, correspondingly offset laterally, as an eccentric 17, which in turn supports the stator end of the link 7.
  • the angle can be adjusted by which the eccentric bolt 14 is rotated, and with the rotation, the eccentric 17 is changed with its horizontal position component, which is transmitted via the handlebar to the chock 3, so that this is horizontally displaceable or adjustable by means of the eccentric bolt.
  • FIGS. 3 and 4 Modified versions are shown in FIGS. 3 and 4.
  • the stand beam 18 has a fixed pin on which an eccentric bushing 20 is mounted. This is also with a worm wheel 21 which is adjustable by means of a worm 22, so that the eccentric 23 also changes its position with the latter.
  • the pin 25 is arranged in the stator frame 24 according to FIG. 4, and an eccentric bushing 26 can be rotated about the pin 25, the eccentric 29 of which projects beyond the end face of the pin 25 in such a way that a strong eccentricity and thus without an undesirably large diameter of the eccentric a large area can be reached.
  • a drive of the eccentric bushing 26 is provided by means of a worm wheel 27 and a worm 28.
  • Alternative drives can, for example, as shown in FIGS. 5 and 6 is shown, are effected by pressure medium cylinders, which are either articulated to a lever connected to the eccentric bushing or the eccentric bolt, or, by means of a rack connected to their piston rod, engage in a corresponding gearwheel connected to the eccentric bushing or eccentric bolt .
  • handlebars attacking from the other side of a chock can contain a stone which is guided in a slot and has the eye instead of a round eye, so that the guidance within the horizontal is determined by the handlebars on only one side.
  • a corresponding control device has an upstream sensor which responds to the respective swivel angle of the handlebars, and one of the screws 16, 22 and 28 can be adjusted as an actuator, if necessary additionally.
  • control device can expediently also be used for setting and, if appropriate, also for adjusting the horizontal adjustment, either by specifying it directly or by specifying values which the adjustment has to follow. Both options are also available side by side: For example, a basic adjustment can be made to adjust two corresponding rollers, e.g. intermediate rollers or work rollers, horizontally in or against the direction of belt travel against the center plane of the stand, in order to find a suitable one especially for thin work rollers , stabilizing position without additional horizontal adjustment devices.
  • two corresponding rollers e.g. intermediate rollers or work rollers
  • a control and regulating device arranged upstream of the eccentrics can take on not only one of these tasks, but several at the same time, so that, for example, adjusting the eccentrics can effect both the horizontal adjustment of rollers and the guiding play of the chocks is adjustable, both the deflection of the uprights and thus the constriction of the uprights under the action of the rolling force can be compensated for in their effect on the guide play as well as the additional horizontal displacement of the articulation axes caused by handlebar deflections.
  • the work roll change is also simplified by increasing the play, and it is possible to enable a roll change even in the case of strip remaining in the street and thus in the stand.
  • FIGS. 5 and 6 Two further exemplary embodiments are shown in FIGS. 5 and 6 .
  • FIG. 5 shows a four-roll stand, in which 30 adjusting devices and chocks for supporting rolls 31 are shown in the window of the stand.
  • Work rolls 33 are mounted in chocks 32 which engage with lateral guide strips in corresponding grooves of guide pieces 34 and are thus axially displaceable against them.
  • the guide pieces in turn are carried by links 35 which are pivotable about eccentric bolts 37 mounted in blocks 36 provided on the outside of the stand 30.
  • the eccentric bolts 37 are rotatably connected to actuating levers 38, the ends of which are each articulated to common actuating rods 39, which in turn are connected to piston rods of actuating cylinders 40.
  • the B-e cylinder 40 By appropriately adjusting the B-e cylinder 40 can be set up so that the adjusting rods 39 and move the eccentric pins 37 rotate about the adjusting lever 38, so that the pivot axes of the links are displaced in accordance with the 35th This can be shifted in the same direction, in the exemplary embodiment to the right, the common vertical center planes 41 of the work rolls against the vertical center plane of the stand 30 by a distance e, so that a horizontal adjustment of the work rolls relative to the backup rolls is achieved.
  • a similar arrangement can be made for a six-roll stand, as shown in FIG.
  • adjustment devices and chocks for support rollers 43 are provided, which act on an intermediate roller 45 mounted on an adapter 44, which in turn are in contact with work roller 46, which are mounted in connectors 47.
  • the chocks 44 of the intermediate rollers 45 are guided, optionally axially displaceably, between guide pieces 48, which in turn can be adjusted with low friction axially by means of links 50 which, in blocks 54, support the eccentric bolts 52 stored in blocks 54 are pivotable.
  • the chocks 47 of the work rolls 46 are held between guide pieces 49, which are guided by links 51, the pivot axes being designed as eccentric bolts 53.
  • the eccentric bolts 52, 53 are mounted outside the stand in blocks 54 connected to the stand in order to advantageously achieve long handlebars and to simplify the processing of the stand.
  • the eccentric bolts are each connected to adjusting levers 55 and 56, the adjusting levers on one side of the stator each engaging a common adjusting rod 57 which can be adjusted by an adjusting cylinder 58.
  • the additional horizontal adjustment given when pivoting the handlebars can also be compensated for with such a control device under the action of a sensor that detects the respective pivoting angle of the handlebars.
  • additional forces can be introduced via the handlebars, which can be used to balance the upper roll internals as well as to perform the roll bending.
  • pressure medium cylinders provided for balancing and / or bending can act directly on the handlebars or, via a second, possibly angled lever arm, of two-arm links.
  • the frictional forces which may be undesirable as a hysteresis and have to be taken into account in vertical movements, are substantially reduced, the manufacturing outlay is reduced, a compact adjusting device for horizontal adjustments is created, and there is the possibility, in a simple manner, for example of Balancing forces, but also bending forces, to be brought about by external cylinders, so that the usual difficulties of the compact construction within a cylinder block are avoided and the spatial limits to be observed can be exceeded.
