Definitions
- the invention relates to a rolling stand, in particular Duo or Quarto roll stand, comprising bending and balancing devices for axially displaceable rollers, wherein on both sides in the window of each roller stand each a stationary guide block is fixed in the height range of the roll chocks and the force of Bending cylinders on the guided in the axial direction and vertically displaceable Roll chocks is transferred.
- Such a bending device with shift system for work rolls is for example, EP 0 256 408 A2 has become known.
- the the bearings for the Work rolls receiving chocks are there via one each in the middle Height range arranged sliding surface on a guide paragraph of pairs arranged pressure transmitting bodies arranged, each about two between them arranged bending cylinder in the vertical direction let it push apart.
- the lower one Pressure transfer bodies are also used to increase the guide length a central guide leg provided in the area of the respective protruding upper pressure transmitting body and into a guide groove of the Guide block engages between the two guide webs.
- the upper ones Pressure transmitting body which has a receiving recess for the Forming guide legs of the associated, lower pressure transmitting body, have for further guidance against the lower pressure transmitting body protruding, in a guide bush of the lower pressure transmitting body projecting guide pin on.
- the bending cylinder of this known device are symmetrical to the Guide pin arranged so that the upper pressure transmitting body the Form cylinder, while the piston rods in receiving recesses of are supported lower pressure transmitting body. Since the bending cylinder here are provided between the mutually associated pressure transmission bodies and not supported on the stator guide block, one can through the Bending of the work rolls conditional bending stress of Guide blocks and thus the roll stand can be avoided.
- the guide blocks are thus on the roller side to Vertical guide of a lower lifting housing and an upper lifting housing in profiled in the shape of a U with angled legs.
- the lifting housing embrace the angled thighs claw-like, with around the thighs around the sliding guides are provided.
- the bending cylinders are, however, outside arranged the sliding surfaces, resulting in axial displacements at high moments and thus leads to increased friction on the sliding surfaces. Besides, this is Bending and displacement system limits the adjustment of the axial displacement and is on the order of +/- 50 to 100 mm. The risen higher demands on the tolerance of the belt and the rolling of Special materials, however, require a larger axial adjustment range. A Enlargement of the axial displacement would be in this known Construction but still increase the moments.
- the invention is therefore based on the object, a bending and Balancing device with axial displacement of the rollers to create without additional friction on the sliding surfaces and without increasing the applied Moments allows a larger axial adjustment range or displacement.
- the bending cylinder on upper and lower piston end each formed with a greater length than width and with its longer axis in the direction of the axial displacement of the rollers are arranged running. Due to this different length / width ratio, where elliptical or oval formation is preferred, can be a larger, depending on the design of the longer axis Reach setting range, e.g. +/- 100 to 200 mm, if the longer axis is 100 mm is larger than the small axis, without being applied to the Increase moments significantly, because of the bending piston or the bending cylinder even with the longer displacement always a sufficiently large Support surface is available. Due to the inventive design the bending cylinder of the rolls of a Duogerüstes or the work rolls of a Quarto scaffolding, the bending forces are also within the slip planes applied, whereby an additional friction on the sliding surfaces is avoided.
- the bending cylinders consist of two telescoping sleeves, of which a sleeve a Moving piston receives, which has a pendulum support with the other Piston sleeve is connected.
- a floating arrangement at the piston sleeve with the impingement of the other sleeve, this poses in the installation position is usually the upper end of the bending cylinder, im Guide block moves up or down.
- a preferred embodiment of the invention provides that the displacement piston receiving sleeve and the piston sleeve in its intermeshing central portion are formed cylindrical and end each elliptical or oval.
- the Slipping of the sleeves thus takes place in the cylindrical middle section, while the end elliptical or oval sleeve training for the increased axial adjustment range provides increased contact surface.
- the elliptical or oval shape can be easily produced and good against manufacturing technology Impurities, e.g. Tinder, caulk.
- Duo or Quarto are in 1 in a window 1 of a roll stand 2 with its chocks. 3 stored work rolls 4 and 5 shown.
- the end in the Rollers 4, 5 mounted opposite roller stands can be adjusted vertically in the window 1 of the two opposing roll stands 2, of which is shown in Fig. 1, adjust to this vertical adjustment to influence the bending curve of the rollers 4, 5, in particular in Connection with a conventional axial displacement of the rollers 4, 5.
- each roller stand 2 stationary guide blocks 6 in the height range of Roll chocks 3 provided.
- These are with bending devices 7 of which there are two and thus four in total in each window are.
- Each bending device 7 has a bending cylinder 8. This consists of an upper, above a bolted cover 9 above closed sleeve 10 and one in the installation position shown lower, up and down movable Piston sleeve 11.
- a displacement piston 12 is arranged, which has a Pendulum support 13 is connected to the lower piston sleeve 11.
- the pendulum support 13 is crowned at the ends and acts with complementary, on the one hand in the Displacement piston 12 and on the other hand provided in the piston sleeve 11 Pressure pieces 14 and 15 together.
- Pressure fluid holes 16 Lead from the side of the lid 9 Pressure fluid holes 16 to a formed in the lid 9 start-up pressure chamber 17, which - with the adjustment of the displacement piston 12, as shown in Fig. 1 - in a pressure chamber 18 of the upper sleeve or displacement piston receiving sleeve 10th passes.
- the chocks 3 of the work rolls 4 and 5 are supported by support lugs 20th and intermediate sliding plates 21, which in the axial displacement of the rollers 4, 5 by means of the axial adjustment, not shown, the shifting of the chocks 3 with respect to the bending devices 7 and bending cylinders 8 facilitate on the one hand the covers 9 and on the other hand, the end-side faces of the Bottom of the piston sleeves 11 from.
- the bending cylinder 8 As closer to a bending device 7 in detail facing Fig. 2 to 5 to is removed, the bending cylinder 8 to increase the adjustment for the axial roll displacement at each of its upper and lower piston ends, i.e. in the area on both sides of the centrally intermeshing center sections or the cylindrical sleeve portions 10a and 11a oval or elliptical (see FIGS. 4 and 5).
- the bending cylinder 8 or its elliptical, oval or like curved end portions of the sliding piston receiving sleeve 10 and the piston sleeve 11 are in the bending device 7 so arranged that the longer axis 22 (see Fig.
